Chapter 1 Introduction

1.1 Mobile Communications History in

Spain

Mobile communications sector is constantly improving, in Figure 1 can be

observed how this fact were carried on in Spain since the appearance of the first

mobile terminals in 1980.

Figure 1: Technology Evolution in Mobile Communications

5

As is shown in Figure 1, different generations were defined:

• 1G [1] refers to the first wireless analog terminals distributed in 1980,

they could only transmit voice without data. Receivers used to add noise

and the power consumption of the devices was very high. No standard

was universalized, the most important ones were NMT (Nordhic Mobile

Telephone), AMPS (Advanced Mobile Phone System) and TACS (Total

Access Communications System).

• The "2G generation" is not a specific standard, but rather marks the

transition from analog to digital telephone, which means, introduction

of series of protocols, improving call handling, more simultaneous links

in the same bandwidth and the integration of other additional services

to that of voice, among which stands out the Short Message Service or

SMS (Short Message Service). In this generation, we can talk about the

first universal standard, GSM [2] (Global System for Mobile). Currently,

is rare to find a country where there is no GSM system. Its main

characteristics are the following ones:

o The robustness (probability of not losing information from a

communication) is much higher than the first generation case. In

addition, it offers the possibility of transporting not only a voice

conversation, any type of digitized information is transported

too.

o It allows roaming, that is, all the GSM networks in the world

communicate between them in order to temporarily accept users

from other networks.

o It allows handover, which is to get all the BTS (Base Transmitter

Station) in a network to communicate with each other to transfer

6

calls without being cut off when the mobile phone is in

movement.

o It is a cellular network, which implies that to design it, the

territory is divided into cells or hexagonal cells, each with a

capacity to carry out calls. If the number of users of a cell grows,

it is possible to subdivide that cell into smaller ones simply by

installing more BTS within it.

o The power emitted by these antennas and mobile therminals

themselves within the cell are self-regulating, so that the signal

has the exact range and does not exceed the new smaller limits,

and thus does not interfere with calls from other cells. This allows

increasing the capacity of the network with very low costs.

o As a consequence of this power regulation that occurs in mobiles,

the battery lasts longer, since if the BTS is close, it emits less

energy to reach it.

o In Europe, it uses 2 frequencies 900 MHz (EGSM) and 1800 MHz

(DCS) using 2 chanels: uplink and downlink in FDMA/TDMA as

access mode, that is, each user is assigned a transmission

frequency slot or time slot within a bit frame; as well as frequency

diplexing (FDD). In this way, several users can share the same

frequency each in their time slot. This requires implementing

synchronization techniques on the network.

• Given the lack of performance of 2G systems for data transmission (2.5

G), this evolution was made as an improvement of the same. Packet

switching (PS) is implemented for the first time, compared to circuit

switching (CS) used until then for the main service offered (voice). The

big advantage is that it can be deployed over existing 2G infrastructures,

making it less expensive than a new, more data-specific network. The

most famous standard is GPRS [3].

• With the development of internet services and the creation of

multimedia content, together with the global massification of the

internet, it was necessary to improve the speed of voice and data

transmission as well as QoS, with which 3G and its most famous UMTS

900/2100 [4] standard emerged in the year 2000. UMTS uses WCDMA

(Wideband Code Division Multiple Access) this fact allows different

users who are transmitting a signal at the same time to use the same

frequency. The most relevant features of this generation over 2G are

outlined below.

o It allows asymmetric traffic support on uplink (UL - uplink) and

downlink (DL -downlink).

o Maximum transmission speed grows to 384 Kps.

o Robustness of the system, security increases.

o It can be done a handover between both technologies (EGSM and

UMTS), improving the load balancing and coverage footprint.

o BTS are named NodeB in 3G systems.

o It can be multiplexed different quality services (voice and video)

in the same connection.

o Carrier size increases to 5MHz.

Later on, HSDPA/HSUPA and HSPA+ [5] protocols were released with

the following objectives: to get better data rates and to improve QoS as

well as the spectral efficiency. HSPA+ introduces the possibility to make

an “all IP” architecture, it is the definitive step to the 4G.

• With the development of technology in user terminals and the

continuous access to mobile data networks and high-bandwidth

multimedia applications has led to the implementation of 4G systems.

As a result, LTE [6] standard (Long Term Evolution) was defined.

LTE does not meet all targets set for 4G in order to QoS and data rate, so

few years later the standard LTE-Advanced appears to achieve these

objectives. It is characterized by using a radio interface based on

OFDMA (Orthogonal Frequency Division Multiple Access), with

variable carrier bandwidths (1.4MHz-20MHz) in downlink and SC-

FDMA (Single Carrier FDMA) in uplink. This modulation allows the

implementation of the different antenna technologies, known as multi-

antenna techniques or MIMO (Multiple Input Multiple Output) in a

heterogeneous network where compatibility with UMTS / HSPA

networks will already be feasible, improving up to four times the data

transmission efficiency.

LTE network works over IP (All IP), this fact drives the simplification of

the system: The RNC (Radio Network Controller) that in 3G is in charge

of radio resource management (RRM) and part of the mobility

management (MM) of the NodeBs that connect to it, is eliminated in LTE

where these functions are integrated into the new eNodeB (evolved

11

NodeB) that can be interconnected with each other ,if they are in the

same area, through the new X2 Interface.

This generation gives a better performance than 3G in different features:

o Maximum peak transmission speed in DL grows to 1Gbps

(actually, with high mobility, a data rate between 100 and 300

Mbps is obtained).

o Bandwidth varies between 5MHz to 20 MHz. It depends on the

frequency band that is used, LTE has four of them in: 800 MHz,

1800 MHz, 2100 MHz and 2600MHz.

o MIMO (Multiple Input Multiple Output) antennas are used

increasing network’s capacity.

1.2 Objectives

The main objective in this Master Thesis is to expose the integration process of

a new LTE band in an existing NodeB. For this, a RAN Sharing work has been

selected. This work consists of sharing with another Operator 2 the radiant

system, as well as the node, giving service to the Operator 2 from the active

equipment of the Operator 1 maintaining the core of each operator's network

separately.

The project is divided into the following milestones, which will be explained in

detail in the main part of the report.

• Need for 4G coverage of the operators involved: Usually certain villages

in the target area of the operators do not have a good 4G coverage. To

deal with this problem, Operator 1 searches for its own existing nodes

(candidates) that are close to this area to cover it. If Operator 1 does not

find a good candidate, and if Operator 2 has nodes of its own that can

solve this problem, they will enter the project as crossed nodes

(management of nodes transferred by Operator 2 to Operator 1 working

as RAN Sharing).

• Design: First, Operator 1 gives a file that contents the hardware that

were approved by them, with this information, blueprints of the BTS

and using different Operator’s 1 tools to view antenna’s tilt as well as

13

extra hardware information. Knowing this, a guide is prepared with

which the technician who is going to visit the site must take into account.

Subsequently, with the information collected by the technician and the

objectives set, the hardware components with which the equipment

swap is to be performed and their parameters are selected, to perform a

simulation of coverage and interference as well as PIM (Passive Inter

Modulation). If the prepared report is approved by the operator, the

necessary material is requested and the location information is updated

by its managers.

• Integration: In this part, another company usually does the integration

work, remotely Arca operations team is in charge of loading the

necessary software resources for the correct operation of the node. The

design team generates a file with the parameters to be taken into account

at the time of integration by the operations team. After integration, the

KPIs will be monitored, corroborating the correct operation of the

station.

For confidentiality reasons, all BTS data, parameters, statistics, operators, etc.

that are explained in this Master Thesis, are generic.

Chapter 2 Design and Integration of

New LTE Band in an Existing Node

The presentation of the content of this section, follows the distribution of the

tasks described in the objectives section of this report: Study of current LTE

coverage in a target area and candidate choice, design phase and integration

phase.

2.1 Study of Current LTE Coverage in

Target Area

First, the operator detects lack of LTE coverage in a certain area, either due to

customer complaints or previous studies that were carried out, once the lack of

coverage is detected, it begins to search for nearby nodes (Candidates) that

implementing in They new LTE bands or simply updating the radio equipment

(swap) to cover the demanded area. If the operator does not have nearby nodes,

and another operator has a node to help achieve the stated objective, he will

negotiate with him to request the sharing of the site or the Radiant System and

radio equipment (Ran Sharing). If the selected node is owned by Operator 2

and gives it up for Operator 1 to make Ran Sharing with their equipment, it is

15

called crossed node and, in turn, the area is called the sharing area, so coverage

will have to be evaluated of both operators in the design phase.

In the area shown in the image which is in a sharing zone, it has been observed

that population areas and roads are not covered with LTE. Observing the

operator stations near the coverage target, it is observed that there are two BTS

radiating 2G and 3G in coverage-oriented low bands. Therefore, two possible

candidates for integration are obtained. Operator 2 has enough coverage in this

area, but he wants to improve it, both operators make a deal to share the

selected candites to do Ran Sharing. Once both candidates have been selected,

the Operator 1 makes a feasibility study. When the candidates are approved,

the design phase begins.

Figure 2: Target Area and Candidates Inside it

16

2.2 Design

2.2.1Operator requirements

At the beginning of this phase, Operator 1 generates a file with the hardware

requirements that must be integrated in addition to the frequency bands to be

integrated and those that are already radiating. The file contains more

parameters to consider such as operator codes and information related to the

location.

Figure 3: Hardware Requirements of Node 1 and Node 2

The parameters in the figure correspond to the two nodes selected in the

previous section, it is observed that both nodes are radiating GSM 900 MHz

and UMTS 900 MHz. Candidate 1 has an associated operator Node 2, so it must

be done a swap to operator Node 1 taking into account the initial configuration

of the current node. In addition, the proposed radio equipment is specified:

• RU (Radio Unit): It is a remote radio transceiver that contains the base

station's RF circuitry plus analog-to-digital/digital-to-analog converters

and up/down converters.

17

Currently in the majority of nodes that have not been recently rethought,

they have individualized RUs for each frequency band, the current

objective is to swap these devices with other new multitechnology

equipment capable of emitting in several different bands. In this case,

the RRU 2479 B8 / B20 / 700 manufactured by Ericsson is proposed,

capable of generating carriers in three different bands: B8 (GU900), B20

(L800) and 700 MHz, which is expected to be one of the new bands for

5G that are used after the new digital dividend. Using this equipment,

costs are reduced and tower loading is improved as well as spectral

efficiency.

• BBU (Baseband Unit): It is a device that transports a baseband

frequency without modulation from a remote radio unit to which it may

be tied through optical fiber. These BBUs replace the old DU (Digital

Unit): DUG for GSM, DUW for UMTS and DUS for LTE. Their function

is the same, but with the new BBs, several technologies can be integrated

in the same team, they have more capacity and better throughput. The

Basebands that are currently being integrated are the BB5216 that

supports 2G 3G 4G and the BB6630 that supports the same technologies

in addition to 5G and has a greater capacity and number of available

ports, both manufactured by Ericsson.

• SSRR Target: It refers to the distribution of low and high frequency

arrays that the antennas of the site must have, each array is made up of

two physical connectors L means low bands and H high bands. A 2L2H

target is chosen to be able to use MIMO 2T4R (two mouths transmitting,

four mouths receiving) in the L800 band and 2T2R in the GU900, the two

high frequency matrices, are reserved for a possible later integration of

high bands capacity oriented to be integrated with MIMO 4T4R.

18

2.2.2Pre-Design and Visit to the node

Before the visit to the node site by the infrastructure team, it is necessary

to do a remotely access to the node using the manager enabled by the

operator and consult the blueprints of the node to verify the hardware

equipment of the node, as well as its main parameters: orientation

mechanic and electric inclination of the antennas, as well as the power

with which the RUs are currently transmitting the different frequency

bands. With this information and analyzing the operator's requirements

to define what is necessary to change at the node, a report called pre-

design is prepared, in which the technician in charge of the visit is

guided to make the appropriate measurements and verify the status of

the radio equipment.

Figure 4: Current Radio Equipment and Configuration of Node 1

19

Having a look to the scheme of the radiating system of the selected node

and applying the operator's guidelines, the following actions are defined

in the pre-design:

• The orientation of the antennas is 140º and 270º. So there are two

sectors, since the work is of the equipment swap type, these

azimuths are maintained. The MT of the antennas is 0º and the ET

is 6º for sector 1 and 7º for sector 2.

• The K80010309 antennas must be changed, they only have one

low band array (1L), the number of arrays required is two low

band arrays and 2 high bands (2L2H). The proposed antenna

model is a larger CCCxxxR25 antenna, it is necessary to carry out

a study of loads during the visit.

• Different passives are observed in the SSRR: TMAs (Tower

Mounted Ampliffier), arresters and splitters. The SSRR should be

kept as clean as possible so they should be uninstalled if possible.

• If the remote node manager is accessed, the existing RU model

(RRUS01 B8) and its DU (DUW 20 01) are obtained. It is necessary

to change both as described in section 2.2.1 (swaping) for new

multi-technology equipment, respectively RRU 2479 B8 / B20 /

700 and BB 6630 to integrate the L800 band.

20

Figure 5: Current DU and RU in Node 1

• Finally, it must be verified if the antennas have RET (Remote

Electrical Tilt) control, that is, if their electrical inclination can be

remotely controlled by the remote operator's manager. If this is

the case, it must be verified that the tilt obtained matches the one

that appears in the SSRR, if not, what the remote manager

indicates prevails. The antennas of the node under study do not

have RET control.

In addition, during the visit it is necessary to verify the connection of the

electrical network and its energy equipment, it is also reviewed how

loaded the tower is, since it can lead to restrictions regarding the

situation of new equipment and the size of antennas. Finally, the length

of the new SSRR cabling is estimated.

2.2.3Design File

After visiting the site, Radio and Infrastructure teams jointly prepare the

design proposal presented to Operator 1. The restrictions seen at the

node are taken into account in case it is necessary to change the antenna

21

model for one of Smaller size, limitations in terms of available space in

the cabinet where the BBUs are located, and other power and ethernet

transmission equipment.

The design file has the following fields:

• TRX number (G900) or carriers

• Final technologies: technologies that will radiate upon

completion of integration.

• Number of connectors used for transmission and reception, that

is, the MIMO type.

• Radiation power.

Figure 6: Final Power/MIMO/Carriers Configuration of Node 1

• Summary of adjustments at hardware level and SSRR: what is

necessary to disassemble, replace and install. The work to be done

on the node is:

o Disassembly of RBS6601, DUs and old SIU in charge of

alarm management, in the outdoor cabinet. It is also

necessary to remove the RRU01 B8 and remove the RF

wiring corresponding to these uninstalls.

o Install two new BB6630 (one is reserved for future new

technologies), must be powered from circuit breakers in

DC-BOX as well as connect the new alarm management in

it.

22

o Replace Operator 1 and 2 antennas with two new

CCCxxxR25 antennas at the top of the tower, it is necessary

to make a Hot Swap, that is, make a cut in the service of

both operators at the time of integration, in turn the two

are installed new RRUs 2479 B8 / B20 / 700 with new power

cables to the DC-BOX, as well as wiring with new fiber

optics to BB6630 and with new coaxial cables to the

mouths of the antenna. The new antennas have internal

RET, their management is configured through the L800

band in the new RRUs.

• Finally, a table with the sectorization and its parameters is

attached.

Figure 9: Final Node 1 Sectorization

2.2.4Simulation of Radio Coverage and

Interference

Once the design file is closed, a radio coverage and interference

comparison is made between the current state of the designed nodes and

24

their state after applying the work described above. This simulation is

carried out using the Xirio Online tool approved by Operator 1 to define

ET and MT as well as orientations of the node sectors.

The tool has an inventory where previously the studies of the current

state of the network of Operator 1 have been saved, as well as the studies

corresponding to Operator 2 but with restrictions (only data related to

the location and directions of the sectors are provided, the others

parameters are generic). Using these coverages, a multi-coverage study

is created by technology of each operator, that is, all the coverages

(sectors of each node) grouped by bands and operator are taken to be

simulated together.

Before simulating the current state of the project, it is verified that the

parameters of the individual coverage correspond to what was observed

in the visit to the node and in the manager's queries, as reflected in the

design file, updating parameters if it would be necessary. In the Figure

10 it can be seen an example of the input file of a 2G coverage studio.

Figure 10: Input File of a 2G Coverage Studio in Xirio

Main common parameters for the studios of all technologies:

Transmission Power, Antenna model, Antenna height, Azimuth,

ET/MT, MIMO type, Feeder losses and traffic loading.

There exists specific parameters for each technology too:

25

• In 2G, the DL frequency of the BCCH (Broadcast Control

Channel) channel is the essential parameter to take into account

for a correct simulation of interference in the area. Defines the

control channel within the GSM frame that contains the main

frequency of the cell, that is, none of the neighbors close to the cell

should use that same frequency or, if possible, the adjacent ones,

to avoid co-channel and channel interference adjacent. It takes

seventeen different values with 200 kHz of bandwidth.

• On the other hand, 3G and 4G have fixed frequency in the

downlink channel regarded to the frequency band that is used.

Furthermore, 4G uses the PCI [7] (Physical Cell Identifier) as the

identity of the LTE cell. As in 2G with the BCCH channel, cells

with the same PCI can cause interference, so it is important to

ensure that there are not three cells with the same PCI in a large

area (for 25 km2). The eNodeB can select the PCI from a list of

possible identity values. There are 504 single physical layer cell

identities, grouped into 168 groups of three identities in LTE. The

primary sync sequence (PSS [0-2]) and the secondary sync

sequence (SSS [0-167]) in a given cell are used to indicate the PCI

to the UE.

PCI=3*PSS+SSS

After loading all the coverage studies necessary to perform the multi-

coverage simulation, the calculation method that will be used to obtain

the results must be specified as well as the morphographic layer. Xirio

uses a series of basic or standard propagation models (see Annex 1),

generally promoted by international recommendations, to which is

added the possibility of configuring certain parameters for a more

26

precise adjustment due to specific planning circumstances specified by

the operator. In this project two calculation methods are differentiated:

urban and rural. In this case, the simulation was launched as a rural area,

obtaining the following coverage and interference footprint in the

current state of the L800 network.

Figure 11: Current Coverage Simulation

27

Figure 12: Current Interferce Simulation

Thresholds for LTE were specified by operator 1.

The next step is to create new multi-coverage studies from the current

state, modifying its coverage studies with the parameters specified in

the design file. When applying the changes to Node 1 and Node 2, the

simulator returns the coverage and interference traces seen in the

following images.

28

31

It can be seen that the coverage footprint improves while the interference

footprint remains practically unchanged in areas that already had LTE

coverage. At this moment, if the network deployment objectives are not

met, it is time to modify the tilts or orientations proposed in the design

in order to improve the results obtained.

Another option available to Xirio is the generation of coverage and

interference statistics by population and area with respect to the

thresholds previously defined in their respective radioelectric footprints

simulations. This allows a detailed analysis of the signal reaching the

areas of interest in the target area.

Figure 17: Coverage Statistics Export from Xirio

Figure 18: Interference Statistics Export from Xirio

Using this information and the radioelectric coverage footprints, a

report is generated for Operator 1 with all the technologies object of

simulation, attaching a summary table to observe the future state of the

area's network with respect to the current state. The same process must

be done for Operator 2 coverages.

32

Figure 19: Comparison Table of Currrent and Final State Statistics

2.2.5 PIM Simulation

Parallel to the Xirio simulation, the PIM [8](Passive Intermodulation)

simulation of the system is performed. PIM is a form of intermodulation

distortion that can occur when no active components are present. It

arises from the action of passive components or elements that have non-

linear responses to any signal. It can be generated by a variety of

components and objects: everything from coaxial connectors to cables,

even rusted bolts or any joint where dissimilar metals meet. Even some

normally "linear" components can generate PIMs.

PIM can create interference that will reduce the reception sensitivity of

a cell or even block calls. This interference can affect both the cell that

creates it, as well as other nearby receivers. It is critical to identify the

elements of the SSRR and nearby metallic elements that can carry PIM.

The PIM is created by a high power transmitter, so the simulation must

be done with 100% load to deal with the worst case.

33

The simulation is processed in an excel macro supported by Operator 1,

to use it correctly it is necessary to analyze the consolidated state of the

SSRR of the station of interest. If the components that make up it are

new, there should be no PIM problem, but if some components are

reused, their deterioration could be critical in this regard. In the case of

Node 1, its entire radiant system gets new, with no passives in your

SSRR, just the antennas and cables. Both elements generate very low IM

products in tests of 2 carriers at 20 W each, -153 dBc and -170 dBc, so the

value of the antenna is taken as limiting for the simulation.

It is necessary to perform a simulation by mouth of the used antenna, in

Node 1 case, the idea is to radiate GU900 + L800 for both operators. The

distribution at the mouth of the antennas and RRUs will be:

Table 5: Input Parameters for PIM Simulation

Technology G900 U900 L800

Power (dBm) 40 46 43

Configuration 1T2R 1T2R 2T4R

Threshold

(dBm/RBW)

-104 -100 -114

RBW (MHz) 0.2 MHz 5MHz 0.2MHz

In addition, it is necessary to differentiate the frequencies used by each

operator in the frequency bands. The central frequencies of the downlink

channels for both operators in U900 and L800 and BCCH in G900 are

considered to perform the simulation.

34

The process followed to carry out the G900 simulation is detailed, in the

rest of the technologies the same process is followed, it is simply

necessary to establish a threshold and an adequate resolution

bandwidth to differentiate the carriers of each technology.

The input parameters of the PIM simulator are colored blue in the table,

it is observed that the power differs from that specified previously in

G900 and U900 of Operator 2, this is due to the fact that the operators

use different arrays to transmit these technologies, Therefore, it is

considered that one operator is the one that transmits while the other

interferes at the rate of the configured power minus the cross polar

isolation between arrays that the antenna has -26 dB in this case.

Figure 22: Table of PIM Simulation GSM 900 Operator 2

Figure 23: PIM Simulation Result GSM 900 Operator 2

In the result obtained we can see that the PIM received in all bands is of

a low value, we can see in the graphs of the simulation of both operators

how the power spectral density of PIM in the area of the spectrum in

which the Uplink bands of the technologies is relatively low compared

to the established threshold. It is only compared with the uplink channel

since the power spectral density of the downlink channel will always be

much higher than the PIM generated, so it will not generate problems in

that band.

2.2.6 Blueprint

The last task of the design part consists of updating the station blueprint

with the work to be carried out described in the design file, as well as

the correct location of the hardware components to be installed with the

wiring and their dimensions together with a table with the main

parameters of the sectorization of technologies. Operator 1 needs to

validate the files and simulations described above to be able to perform

this process. It should be noted that an operator demand is to place the

new RRUs close to the antennas, so if there is no adequate support to

locate them, it is necessary to add a mechanical tilt kit, whose second

function is to hold the RRU behind the antenna . In this way, losses due

to signal transmission in coaxial cable are avoided since the FO losses

are lower, as well as not requiring additional passive elements such as

TMAs or arresters.

2.3 Integration

Months after closing the design tasks, the operator gives an integration order

on the node, so a date is established to carry out the work. Before that day, it is

necessary to prepare a series of files that are described in the following sections.

2.3.1 Integration Files

Prior to the integration, a network export of the node should be carried

out, similar to the one carried out in the pre-design phase to check its

current status, especially the existing alarms, configured power and

antenna tilts.

Using this information, a report is prepared for the operations group

with everything they need to take into account to achieve a correct

integration. This report is made up of different sections, such as the work

to be performed to replace equipment, as well as the initial configuration

of node technologies and those that must be implemented after the

integration. Also, the contribution of the different passives is specified

in terms of losses and delay, TMAs usually add 0.3dB of losses and a

delay of 0.3 ns to the signal for example.

In parallel, an integration template is developed that the operations

team will follow to make the necessary remote configurations on the

node. Consists:

• Band to integrate, name of the eNodeB and site

42

• Cabinet model

• DU Model

• RRU Model

• EnodeBId: code that identifies the LTE node, the first two digits

identify the province and the next four the node.

• RRU port: port where the FO will be located in the RRU for its

communication with the BBU.

• Transmission ports: number of ports of the RRU to be used as

transmitters.

• Configured power

• Mixed Mode: parameter that must be activated if the RRU is

going to be used in more technologies other than the new one.

43

• Eutrancell FDD Id: name of the cells to integrate.

• TAC: It is the unique code that each operator assigns to each of

their TAs (Tracking Area: a group of neighbor eNBs in a located

zone).

• Euarfcndl: it stands for E-UTRA Absolute Radio Frequency

Channel Number that is the carrier frequency in downlink.

• CellId: LTE cell identifier, it is different for each band.

• Physical Layer Cell Id group: PSS for PCI calculation.

• Physical Layer Sub Cell Id: SSS for PCI calculation.

• RACH Root sequence [9]: Random Access Channel is a LTE

uplink transport channel responsible for sending connection

request information. It is executed in the initial access of a UE to

the network, although it can also occur in an RRC (Connection re-

establishment) due to a failure in the radio access or in case of

handover for example. RootSequence, refers to the identifier of

the first root sequence of the RACH channel, it depends on the

radius of the cell to be considered, Ericsson considers a cell radius

44

of 15 km, using 10 root sequences per cell, although Operator 1

reserves 15 sequences per cell. The standard defines 838

sequences from 0 to 837.

• Channel Bandwidth

Figure 30: Integration Template

When radio equipment is changed and for integrating the new

frequency band, it is necessary to request a license from Ericsson to

activate a series of features in the node for its correct operation. The data

fields are described in Annex 2.

45

2.3.2 Integration Day

At the time of changing the equipment, the technicians perform the

work in Hot Swap, coordinating with the operations team to make the

remotely programmed configurations. Once the integration is complete,

the radio equipment is in charge of verifying that all the necessary

configurations have been carried out correctly, for this the Integration

Review Template is covered, which consists of verifying the segments

that can be seen in the Figure 31 and they are explained below.

Figure 31: Integration Review Template

To verify if the LTE frequencies have been defined correctly, it is

necessary to make sure that each cell of the node has a reselection to that

frequency, this allows the mobile terminals to detect the frequencies of

the area and in this way the device measures in said frequencies and If

it detects a better signal level and quality, it goes to another carrier, in

the Figure 32, the example for the L800 cells is shown.

46

Figure 32: LTE Reselection Frequencies in Node 1

The KPIs (Key Performance Indicator) of all the node's technologies are

analyzed. They are metrics that are used to quantify the results of a

certain action or strategy based on predetermined objectives; that is,

indicators that allow measuring the success of the actions taken in

integration. For an integration to be considered correct for the operator

and to be approve, it must be analyzed once it has been completed by

means of a series of KPIs previously agreed with the operator and these

must show values equal to or better than before the integration into

existing technologies. in addition to exceeding certain thresholds in the

new technology that has been integrated into the node. They will be

analyzed in detail in the following section.

The operator has a file called Baseline in which it establishes the

reference parameters that the node must have and the status of the

features that apply to the integration must be reviewed. In LTE 800 MHz

band, the license features observed in the Figure 33 should be reviewed.

47

Figure 33: License Features to be Reviewed

It is verified that the tac defined in the integration template has been

configured correctly. The same is done with the RET control and the

power configured in the RRU.

Figure 34: TAC, RET and Power Configuration set in Node 1

48

The neighbors relations must be verified, the 4G-4G relations of the node

itself are defined, all sectors are created among themselves, they cannot

be deleted as they are considered fundamental for the site. The rest of

the neighbors are created by the ANR (Automatic Neighbor Relation),

this program needs to have defined the frequencies of 4G, 3G and 2G of

the area (normally 4G L800 L1800 L2600 L2100, 3G U900 U2100 and 2G

G900) with this the program it measures what each sector sees by

creating the neighbors itself and deleting them if they are not necessary.

Figure 35: 2G, 3G and 4G Neighbors of Node1

To check if there are crossed sectors, the field technicians must carry out

a call test at the end of the integration and verify that at all times the

terminal connects to the cells defined correctly. Also they must verify

that the RSSI (Received Signal Strength Indicator) in each sector is below

- 114 dBm in LTE cells, which is the established threshold that is

considered as interference free.

49

Figure 36: Call Test Report

Finally, it is verified that the RRUs have the diversification configured

correctly, that is, the RRUs transmit and receive through the ports they

should. In the case of L800 with MIMO 2T4R, they must transmit

through two ports and receive through all of them.

Figure 37: RRU Configuration in Node 1

50

2.3.3 48 Hours KPIs

When it is determined that the parameterization of the integrated node

is correct with the verification of the ABKI, the next step is to verify that

the new technology meets the thresholds established for the KPIs of

interest, for this it is necessary to perform an average of its KPIs during

the 48 hours after integration, and check that they meet the thresholds

agreed with the operator. Each KPI is formed from the aggregation of

several counters specified by the operator that are obtained from

databases where the operator places the data of its nodes.

Figure 38: KPIs 48 Hours File

51

• DCR (Drop Call Rate): It is the fraction of the telephone calls which,

due to technical reasons, were cut off before the speaking parties had

finished their conversational speech and before one of them had

hung up.

• CSSR (Call Setup Success Rate): It refers to the fraction of the attempts

to make a call that result in a connection with other terminal.

• Iniciated Calls.

• DownlinkTrafficVolume: Amount of traffic handled in the DL

channel

• UplinkTrafficVolume: Amount of traffic handled in the UL channel

• RSSI.

• Availibility Hourly: Percentage of time the cell has been available

during a day.

• MIMO Rank 2 Usage: 2T2R MIMO Usage Percentage

• MIMO Rank 4 Usage: 4T4R or 2T4R MIMO Usage Percentage

• CSFB (Call Setup Fall Back) WCDMA: CSFB is made from 4G to

3G, when a terminal does not have the option to make the call

through IP, so it is redirected to 3G.

• Hodover Attemps over X2: Handover success rate carried out by X2

interface.

• Carrier Agregation: It is a method to increase the data rate per user,

where a group of frequency blocks are assigned to the same user. The

maximum possible data rate per user is increased the more frequency

blocks are assigned to a user. The sum data rate of a cell is increased

as well because of a better resource utilization. In addition, load

balancing is possible with carrier aggregation. Obviously, CA can

only be implemented when there are several LTE bands on the node.

52

When this file is delivered to Operator 1, seeing that all the KPIs meet

the thresholds previously established, the node goes to the Optimization

Department, where the node's optimization stage will be carried out in

order to meet more restrictive thresholds than those set have been

discussed and their parameterization will be reviewed in greater detail.

However, to finalize the integration phase, it is necessary to carry out a

daily monitoring of the node's KPIs until B2R (Build to Run) passes,

which is the stage that Operator 1 certifies that the node is free of errors

at the end of a week after carrying out the integration work.

Chapter 3 Conclusion and Future Lines

To finish this work, a general reflection is made on the project and the results

obtained with it, and the guidelines that are considered necessary in order to

improve them are explained below.

The objectives set by this project have been fully achieved, fully complying with

the KPIs values for the LTE 800 band demanded by the Operator, in addition

to performing an adequate parameterization of the node for the integration

phase, also in the design phase, an adequate internal PIM response as well as a

very satisfactory radioelectric coverage and interference footprint have been

obtained in simulation for both operators involved in the project.

As future lines, the treatment of the node in the Optimization Department

stands out, which will greatly improve the benefits defined in the design phase

by optimizing the node with even stricter KPI values. Also, if deemed

necessary, a project would be approved for the integration of new LTE bands

of higher capacity than LTE800, such as the LTE 1800 MHz band widely used

in rural environments, such as the one described in this Master Thesis. Even

looking further to the future, the installed radio equipment is compatible with

the low frequency band in which 5G is expected to be located after the second

digital dividend (700 MHz band), which implies that this node is already

prepared for a possible deployment. in that band.
