WiMAX ASNNetwork

ZXMBW R9100 belongs to RRU product of ZTE WiMAX BS product(BBU+RRU architecture). Figure 2 illustrates ZXMBW R9100 posi-tion in ASN network.

FIGURE 2 POSITION IN ASN NETWORK

Application The application of ZXMBW R9100 in the forward and reverse linkis described below.

Forward Link: The Connectivity Service Network (CSN) sendsforward signals to Baseband Unit (BBU) via ASN Access Gateway(AGW) for coding and modulation. The BBU sends the modulatedsignals to ZXMBW R9100 via an optical fiber for In-phase/Quadra-ture (IQ) modulation, up-conversion, and power amplification. Af-ter all these processes, ZXMBW R9100 sends the IQ modulatedsignal to Mobile Station (MS) via antenna.

Reverse Link: ZXMBW R9100 receives air-interface signals fromantenna for down-conversion and IQ demodulation. ZXMBWR9100 sends the IQ demodulated signals to BBU via optical fiberfor decoding and demodulation. After demodulation, the BBUsends the demodulated signals to CSN via AGW.

Product AppearanceZXMBW R9100 radio unit is made of cast aluminum metal. It isvery small and exquisite.

System ArchitectureZXMBW R9100 is a remote Radio Frequency (RF) unit that imple-ments conversion between RF signals and baseband signals. It isconnected to a baseband data interface and a baseband I/Q inter-face via fibers and to an antenna interface via a RF cable.

Figure 13 illustrates the ZXMBW R9100 system architecture.

FIGURE 13 SYSTEM ARCHITECTURE

Note:

The real line indicates the system supports 2T2R Multiple-InputMultiple Output (MIMO), and the dotted line indicates the systemsupports 2T4R MIMO that is optional.

In forward direction, WPTR performs digital intermediate fre-quency processing and up-coversion on the forward signalssent by BBU via an optical interface. After being amplified by



WDPA and filtered by WRFE, these signals are transmitted bythe antenna.

In reverse direction, WRFE receives reverse signals from theantenna and transmits them to WPTR for down-coversion anddigital intermediate frequency processing. Afterwards, thesesignals are transmitted to BBU via the optical interface.

Power DistributionAfter being led into ZXMBW R9100, external power is convertedby WRPM into +28VDC and +5VDC to supply for WDPA and WPTR.

Ventilation andHeat-dissipation PrinciplesThe ZXMBW R9100 cabinet is naturally cooled through air cooledfins design on the top and bottom enclosures. Due to the cabinetssmall volume, the heat dissipation facility is maximum.

The fiber interface circuit provides the interface with BBU andsupports fiber loopback and fiber cascade networking mode aswell as fiber framing and deframing.

In forward direction, the intermediate process circuit and theRF process circuit implement forward transmission includingforward baseband signal reception, up-conversion, amplifica-tion and transmission to the power amplifier, standing wave de-tection of antenna feeder interface, and forward automatic andmanual calibration. In reverse direction, they perform receiveband pass filtering, low noise amplification, RF mixing, digitaldown-conversion to baseband rate on received RF WiMAX sig-nals and then transmit them to BBU through the OBSAI pro-tocol after processing them through the optical interface. Inaddition, they implement reverse RSSI measurement and re-verse automatic gain control.

Note:1. A 1/2 feeder is used when the distance between the ZXMBW

R9100 cabinet and the antenna is equal to or shorter than 19m.

2. A 5/4 feeder is used when the distance between the ZXMBWR9100 cabinet and the antenna is longer than 19 m and shorterthan 25 m.

Antenna

The Antenna is an important radio equipment adopted to trans-mit and receive electromagnetic waves. An antenna is classifiedinto omni antenna and directional antenna according to radiationdirection; according to polarization mode, an antenna can be clas-sified into single-polarized antenna and bi-polarization antenna.Generally ZXMBW R9100 adopts the directional 65 bi-polarizationantenna, and the angle is approximately 45. The appearance isshown in Figure 24.

Feeder

The feeder is used to receive and transmit radio RF signals betweenthe antenna and the ZXMBW R9100.

When the distance between the ZXMBW R9100 cabinet andantenna is less, then the 1/2 inch feeder cable is used. In thiscase, the ZXMBW R9100 cabinet is directly connected to the1/2 inch feeder and 1/2 inch feeder cable is in turn connectedto the antenna.

When the distance between the ZXMBW R9100 cabinet andantenna is more, then the 5/4 inch feeder cable is used. Inthis case, the RF jumper is necessary for the conversion.

ASN Network ReferenceModelThe following describes the Access Service Network (ASN) networkreference model. The ASN network reference model developedby the WiMAX (Worldwide Inter-operability for Microwave Access)NWG (Net Work Group) is shown in Figure 25.



FIGURE 25 ASN NETWORK REFERENCE MODEL

The interface of Figure 25 are described in Table 9.

TABLE 9 INTERFACES DESCRIPTION

InterfaceName

Description

R1 Air interface between the terminal and the RRU.

R3 The interface between the AGW (ASN-GW, AccessService Network Gate Way) and the CN.

R4 Interface between ASNs, i.e. the interface betweenAGWs. It implements some switching-relatedsignaling and established data channel to maintaindata integrity during switching.

R6 The interface between the AGW and the BS.

R7 Internal interface of the AGW. It is selective. Itdivides the AGW into strategy judgment functionand implementing function.

R8 Interface between BSs.

R1 InterfaceThe R1 interface is the connection interface between the AccessService Network (ASN) and the mobile subscriber devices. The R1


Chapter 4 Protocol Interface Description

interface conforms to the IEEE 802.16e-2005 standards agree-ment.

The functions of R1 interface includes providing Media Access Con-trol (MAC) Layer, Physical Layer, and some related managementfunctions

Message Format Figure 26 illustrates management message format of the R1 inter-face of Media Access Control (MAC) Layer.

FIGURE 26 R1 MESSAGE FORMAT

The management messages of MAC Layer are presented in MACProtocol Data Unit (PDU) payload. All management messages ofMAC Layer are composed of an initial fieldManagement MessageType and Management Message Payload. The length of the"Management Message Type" is 8 bit; the type of the managementmessage depends on the requirements of an air interface protocolin IEEE 802.16.

The MAC management messages in basic connection, broadcastconnection, and initial distance-testing connection are not dividedinto chips or bound into packets. But the MAC management mes-sages in the primary management connection can be divided intochips or bound into packets.

Protocol Stack Figure 27 illustrates a schematic diagram of R1 Interface ProtocolStack.

FIGURE 27 R1 PROTOCOL STACK

The R1 interface protocol stack includes MAC Layer and PHY Layer.

Mac Layer

MAC layer of R1 protocol stack contains three sub-layers (fromtop to bottom); Service-Specific Convergence Sub-layer (CS),



MAC Common Part Sub-layer (MAC CPS) and Security Sub-layer.

Service-Specific Convergence Sub-layer (CS)

Different protocol interfaces provide different CS specifica-tions.

The function of Service-Specific Convergence Sub-layer(CS) is to convert/map the external data received by theConvergence Sub-layer Service Access Point (CS SAP) intoMAC Service Data Unit (MAC SDU) and send it to the MACCPS through the MAC Service Access Point (MAC SAP).The other function of this layer is to sort external SDUsassociated with suitable Service Flow Identifier (SFID),Connection Identifier (CID) and Payload Header Suppres-sion (PHS).

MAC Common Part Sub-layer (MAC CPS)

MAC CPS does not need to analyze the load information ofthe CS.

MAC CPS realizes the core function of the MAC layer includ-ing bandwidth distribution, connection establishment andconnection maintenance. It receives data of different CSlayers through MAC SAP and sort them based on differentMAC connection. Quality of Service (QoS) is applied in datatransmission and scheduling of physical layer.

Data, PHY control information and statistical informationbetween the MAC CPS and PHY is transmitted through PHYSAP.

Security Sub-layer

MAC contains an independent security sub-layer to provideauthentication, security key exchange and realize encryp-tion.

PHY Layer

The PHY layer of R1 protocol stack contains multiple regu-lations. Each regulation corresponds to a specific frequencyrange and application.

The PHY layer of R1 protocol stack is based on the modulatingmode of Orthogonal Frequency Division Multiplexing (OFDM).

Baseband-RF InterfaceBaseband-RF interface connects BBU and RRU with compliancewith OBSAI RP3 protocol. BBU and RRU accordingly designed caninterconnect with generality, reliability and flexibility.
