CE Resource Management 2 Overview



2-1

2 Overview

CE resources are a type of NodeB hard resource. The number of CEs supported by a NodeB indicates the channel demodulation capabilities of the NodeB. The more CEs a NodeB supports, the more powerful the channel demodulation and service processing capabilities.

Services at different rates require different numbers of CEs to ensure proper channel demodulation.

In a RAN, CE resources are managed by both the RNC and NodeB, as shown in Figure 2-1. The NodeB reports its CE capacity to the RNC. The RNC determines whether to admit a new service based on the number of CEs that need to be consumed and controls CE resources during CE congestion. This ensures the proper use of CE resources. The NodeB dynamically manages CE resources and rapidly adjusts the number of CEs that can be consumed based on the actual service rate. This increases CE resource usage.

Figure 2-1 CE resource management

A proper use of CE resources increases the number of UEs that can be admitted and improves the service quality of the admitted UEs.

CE Resource Management 3 Technical Description

3 Technical Description

3.1 Basic Concepts

3.1.1 CE

CE is a basic unit that measures the channel demodulation capabilities of a NodeB. CEs are classified into uplink (UL) CEs and downlink (DL) CEs.

One UL CE needs to be consumed by a UL 12.2 kbit/s voice service (SF = 64) plus 3.4 kbit/s signaling.

One DL CE needs to be consumed by a DL 12.2 kbit/s voice service (SF = 128) plus 3.4 kbit/s signaling.

If only 3.4 kbit/s signaling traffic is carried on a DCH or HSPA channel, one CE still needs to be consumed. The number of CEs that need to be consumed by services of other types can be calculated by analogy.

The number of UL and DL CEs supported by a NodeB is determined by the NodeB hardware capabilities and the licensed CE capacity. The number of UL and DL CEs supported by the NodeB hardware is called the physical CE capacity. The licensed CE capacity may differ from the physical CE capacity. The smaller determines the number of CEs that can be used by an operator.

CE is a concept of the NodeB side. On the RNC side, it is called NodeB credit. The RNC performs admission and congestion control based on the NodeB credit. In the UL, the number of Node credit resources is twice that of CEs. In the DL, the number of NodeB credit resources equals that of CEs.

3.1.2 CE Sharing in a Resource Group

To facilitate baseband resource management, NodeB baseband resources fall into UL and DL resource groups. The UL and DL resource groups are independent with each other. Figure 3-1 describes the UL and DL resource groups.

Figure 3-1 UL and DL resource groups

WCDMA RAN




3-2

UL Resource Group

A UL resource group is a UL resource pool shared on a per-channel basis. As shown in Figure 3-1, more than one cell can be setup in one UL resource group, One UL resource group can have multiple baseband boards, but one board can belong to only one UL resource group. CE resources in one UL resource group can be shared by baseband boards. This means that UEs in a cell in a UL resource group can set up services on any board in the group. The physical CE capacity of a UL resource group is the total CE capacity of baseband boards in the group.

DL Resource Group

Different from a UL resource group, a DL resource group is shared on a per-cell basis. As shown in Figure 3-1, resources in a DL resource group are allocated to each baseband board based on cells; one board can be configured to multiple DL resource groups. DL CE resources for UEs in the same cell can be provided by any baseband board in the DL resource group. CE resources in one DL resource group can be shared only within a baseband board.

3.1.3 NodeB CE Capacity Specifications

Different baseband boards of a NodeB have their own CE capacity specifications. For detailed CE capacity specifications supported by each type of baseband board, see the BBU3900 Hardware Description in the WCDMA NodeB Product Documentation.

CE capacity here refers to the number of CEs that can be consumed by UL and DL R99 services and HSUPA services. It does not include CE resources reserved by the NodeB for common and HSDPA channels.

3.2 Rules for Calculating CE Consumption

Introduction

The RNC determines the number of CEs required for a service based on the SF that matches the service rate.

When an RAB connection is set up or released for a service, CE resources must be allocated or taken back and the number of CEs must be deducted or added accordingly. Different rules for calculating CE resource consumption apply to channels or services of different types, as shown in Figure 3-2.

Figure 3-2 Rules for calculating CE resource consumption

CE resources reserved by the NodeB for common and HSDPA channels are shown in gray. CE resources that need to be consumed by R99 and HSUPA services are shown in orange.

WCDMA RAN




3-3

CE Consumption of Common Channels

CE resources required on the UL and DL common channels are reserved by the NodeB. Therefore, they do not occupy the licensed CE capacity. These CEs do not need to be considered in the calculation of CE consumption.

CE Consumption of HSDPA Channels

Similarly, the NodeB reserves CE resources for the high-speed downlink shared channel (HS-DSCH) and the related control channels if HSDPA is used. These CEs also do not need to be considered in the calculation of CE consumption.

Note that the signaling of an HSDPA UE that is not performing an R99 service occupies one DCH and needs to consume one DL CE. If the SRB over HSDPA function is enabled, the signaling of an HSDPA service does not consume additional CE resources. For an HSDPA UE that is performing an R99 service, its signaling and the R99 service occupy the same DCH. Therefore, only the CEs consumed on R99 traffic channels need to be calculated.

CE Consumption of an R99 Service

For an R99 service, the RNC determines the number of CEs and NodeB credit resources that need to be consumed based on the SF that matches the maximum bit rate (MBR) of the service.

CE Consumption of an HSUPA Service

For an HSUPA service, the RNC determines the number of CEs and NodeB credit resources that need to be consumed based on the SF that matches the service rate. The RNC determines the SF based on a certain rate in the following ways:

If the UL enhanced L2 function is disabled and the NodeB indicates in a private information element (IE) that dynamic CE resource management has been enabled in the cell, the RNC calculates the SF based on the larger of the bit rate of one RLC PDU and the guaranteed bit rate (GBR).

If the UL enhanced L2 function is disabled, the RLC PDU size is fixed. The bit rate of one RLC PDU is determined by the RLC PDU size and transmission time interval (TTI).

If the UL enhanced L2 function is enabled and the NodeB indicates in a private IE that dynamic CE resource management has been enabled in the cell, the RNC calculates the SF based on the larger of the bit rate of the smallest RLC PDU and the GBR.

If the UL enhanced L2 function is enabled, the RLC PDU size is flexible. The bit rate of the smallest RLC PDU is determined by the minimum RLC PDU size and the TTI. The minimum RLC PDU size can be specified by the RlcPduMaxSizeForUlL2Enhance parameter.

If the NodeB reports that dynamic CE resource management has been disabled, the RNC calculates the SF based on the MBR.

If the NodeB does not report whether dynamic CE resource management has been enabled, the RNC calculates the SF based on the value of the HsupaCeConsumeSelection parameter and whether the UL enhanced L2 function is enabled.

− If HsupaCeConsumeSelection is set to MBR, the RNC calculates the SF based on the MBR.

− If HsupaCeConsumeSelection is set to GBR:

a. If the UL enhanced L2 function is disabled, the RNC calculates the SF based on the larger of the bit rate of one RLC PDU and the GBR.

b. If the UL enhanced L2 function is enabled, the RNC calculates the SF based on the larger of the bit rate of the smallest RLC PDU and the GBR.

After determining the SF, the RNC searches the CE consumption mapping listed in Table 3-1 for the number of CEs that need to be consumed.

CE Consumption of 4-Way Receive Diversity

The use of 4-way receive diversity does not affect DL CE consumption but doubles UL CE consumption. The use of 4-way receive diversity can be configured by resource group. UL CE consumption of a resource group doubles if the resource group is configured with 4-way receive diversity. CE consumption of a common resource group remains unchanged.

Examples of CE Consumption

UE A, which performs a UL 64 kbit/s and DL 384 kbit/s service on the DCH, consumes three UL CEs and eight DL CEs.

UE B, which performs a UL 64 kbit/s and DL 1024 kbit/s service on the DCH and HS-DSCH respectively, consumes three UL CEs and one DL CE if the DL signaling radio bearer (SRB) is carried on the DCH.

UE C, which performs a UL 608 kbit/s and DL 1024 kbit/s service on the E-DCH and HS-DSCH respectively and at the same time performs an AMR speech service, consumes nine UL CEs and one DL CE.

3.3 Admission and Congestion Control Based on CE Resources

Because CE resources are limited, the RNC needs to perform admission and congestion control based on CE resources. UL and DL CE resources undergo separate admission and congestion control.

3.3.1 Admission Control

The RNC admits a service based on NodeB credit resources (called CE resources on the NodeB side). If the admission fails, preemption and queuing will be triggered.

Call Admission

CE resources to be consumed by common channels and HSDPA services are reserved in advance. Therefore, UEs requesting common or HSDPA channels do not need to be admitted based on CE resources.

Admission control based on NodeB credit is performed on the RNC side. It mainly applies to RRC connection requests, handover requests and non-HSDPA services.

WCDMA RAN




3-6

Admission based on NodeB credit is optional in resource admission control. This function is controlled by the switch parameters CacSwitch:NODEB_CREDIT_CAC_SWITCH and NBMCacAlgoSwitch:CRD_ADCTRL. It is recommended that these two switch parameters are turned on. If these two switch parameters are turned off, the correctness of the channel demodulation may not be guaranteed because of excessive user admission.

For the detailed description of admission control based on NodeB credit, see the Call Admission Control Feature Parameter Description.

Preemption and Queuing Following a Failed Admission

If an admission based on NodeB credit resources fails, preemption and queuing based on NodeB credit resources will be triggered.

Preemption based on NodeB credit resources is similar to preemption based on other resources. The RNC releases the NodeB credit resources occupied by one or more low-priority UEs until the total released NodeB credit resources meet the requirement for the new UE.

If the preemption fails, queuing is implemented to increase the access success rate of the new UE.

For the detailed description of preemption and queuing, see the Load Control Feature Parameter Description.

3.3.2 Basic Congestion Control

When the usage of NodeB credit resources in a cell exceeds the threshold for triggering basic congestion, the cell enters the basic congestion state. In this case, load reshuffling (LDR) is required to reduce the cell load and increase the access success rate. And the following LDR actions are likely to be taken:

BE rate reduction

QoS renegotiation for uncontrollable real-time services

Inter-RAT handover in the CS domain

Inter-RAT handover in the PS domain

The sequence of these LDR actions can be set by running the ADD UCELLLDR / ADD UNODEBLDR command.

For detailed information about LDR triggered by NodeB credit, see the Load Control Feature Parameter Description.

3.4 Admission-CE-based Dynamic TTI Adjustment

As defined in 3GPP specifications, the minimum SF corresponding to an HSUPA UE with 2 ms TTI is SF4. One HSUPA UE with 2 ms TTI therefore consumes a minimum of eight UL CEs. Because HSUPA UEs with 2 ms TTI outperform HSUPA UEs with 10 ms TTI, they need to consume more CEs than the HSUPA UEs with 10 ms TTI. If HSUPA UEs with 2 ms TTI dominate a cell, fewer UEs can be admitted to the cell.

To prevent this problem, Huawei introduced Admission-CE-based dynamic TTI adjustment. With this function, when the NodeB credit resources are insufficient, the 2 ms TTI is switched to the 10 ms TTI to allow more UEs to access the network. When the throughput of the 10 ms TTI HSUPA UE reaches a certain threshold, the 10 ms TTI needs to be switched to 2 ms TTI to achieve higher peak rates.

For the detailed description of this function, see the HSUPA TTI Selection Feature Parameter Description.

3.5 Dynamic CE Resource Management for HSUPA

Although HSUPA improves user experience and increases UL throughput, it greatly increases the consumption of CE resources due to the use of hybrid automatic repeat request (HARQ) and support for soft handovers. If CE resources are allocated fixedly based on the MBR when radio links are being set up, CE resources will not be taken back even if the actual service rate is much lower than the MBR. Fixed allocation of CE resources wastes CEs and easily causes a bottleneck in HSUPA performance. A more energy-saving and efficient allocation method is required.

Dynamic CE resource management for HSUPA services was therefore introduced. With the dynamic allocation, the NodeB performs initial CE allocation based on the GBR of a UE. Then the NodeB periodically adjusts CE resources allocated to UEs based on information such as the user priority and actual rate.

For the detailed description of dynamic CE resource management, see the HSUPA Feature Parameter Description.

3.6 License CE Capacity Alarm

When NodeB CE consumption exceeds a specified threshold of the license CE capacity for a specified period, the NodeB reports the alarm ALM-26812 System Dynamic Traffic Exceeding Licensed Limit).

This alarm is cleared when NodeB CE consumption stays below a specified threshold of the license CE capacity, for example, 90% for a specified period. To configure the CE consumption thresholds and the duration, run the NodeB command SET LICENSEALMTHD.

HSUPA_EDCH_RSEPS_MEAS: Control HSUPA Provided Received Scheduled EDCH Power Share measurement. EMC_UU_ADCTRL: Control power admission for emergency user. RTWP_RESIST_DISTURB: Control algorithm of resisting disturb when RTWP is abnormal. FACH_UU_ADCTRL: Admission control switch for the FACH on the Uu interface. This switch determines whether to admit a user in the RRC state on the CELL_FACH. 1. If this switch is enabled: if the current cell is congested due to overload, and the users are with RAB connection requests or RRC connection requests(except the cause of ""Detach"", ""Registration"", or ""Emergency Call""), the users will be rejected. Otherwise FACH user admission procedure is initiated. A user can access the cell after the procedure succeeds. 2. If this switch is disabled: FACH user admission procedure is initiated without the consideration of cell state. MIMOCELL_LEGACYHSDPA_ADCTRL: Legacy HSDPA admission control algorithm in MIMO cell. FAST_DORMANCY_ADCTRL: Whether to enable or disable state transition of users in the CELL-DCH state, who are enabled with fast dormancy, to ease FACH congestion in a cell. If this switch is turned off in a cell, state transition of such users is disabled. Note that when this switch is turned off in multiple cells under an RNC, signaling storm may occur. As a result, the CPU usage of the RNC, NodeB, and SGSN increases greatly, leading to service setup failure.Parameter withdrawal explanation:The current version supports synchronization and delivery of the setting of this parameter. The RNC, however, does not use this parameter any longer. Later versions will not support this parameter. Therefore, users should not use this parameter. After this parameter is withdrawn, the RNC always performs cell resource admission on Fast Dormancy users. If cell resources are insufficient, Fast Dormancy users cannot enter the CELL_FACH state. If switches above are selected, the corresponding algorithms will be enabled; otherwise, disabled.
