4.4 HBBI BoardThe NodeB HSDPA Supported Baseband Processing and Interface Units (HBBIs) are installedin slots 0 and 1 of the baseband subrack.

4.4.1 Functions of the HBBI BoardThe HBBI provides ports for connection between the RF subrack and the baseband subrack. TheHBBI processes uplink and downlink baseband signals.




Issue 08 (2010-07-31)

4.4.2 Operating Environment of the HBBI BoardThe HBBI receives downlink data from the NDTI (or NUTI) or the HDLP (or EDLP) and thensends it to the MTRU after processing. In addition, the HBBI receives uplink data from theMTRU and then sends it to the NDTI (or NUTI) or the HULP (or EULP, EULPd) afterprocessing.

4.4.3 Operating Principles of the HBBI BoardThe HBBI consists of the control module, interface module, uplink baseband resource processingmodule, and downlink baseband resource processing module.

4.4.4 LEDs and Ports on the HBBI BoardThere are three LEDs and two ports on the HBBI board. The LEDs indicate the running statusof the HBBI. The ports are used to connect to the six MTRUs.

4.4.1 Functions of the HBBI BoardThe HBBI provides ports for connection between the RF subrack and the baseband subrack. TheHBBI processes uplink and downlink baseband signals.

The HBBI performs the following functions:l It provides ports for connection between the RF subrack and the baseband subrack.

l It processes uplink and downlink baseband signals. One HBBI can process the signals ofa maximum of 128 CEs in the uplink and 256 CEs in the downlink.

l The HULP or EULP or EULPd and the uplink resources of the HBBI form an uplinkresource pool. The HDLP or EDLP and the downlink resources of the HBBI form adownlink resource pool. One HBBI can process the signals of three cells in both the uplinkand downlink.

l It supports HSDPA at the maximum rate of 43.2 Mbit/s per board.

The HBBIs are positioned in slots 0 and 1 of the baseband subrack. One HBBI can be connectedto a maximum of six MTRUs.

When two HBBIs are configured,l In a single cabinet, the two HBBIs work in backup mode.

l In combined cabinets, the two HBBIs work independently.

The minimum configuration of the HBBI is as follows:l If MTRUs are configured in the cabinet, a minimum of one HBBI is required.

l If RRUs rather than MTRUs are configured in the cabinet, the HBBI is not required.

NOTE

The HBBI, an enhancement of the NBBI, supports HSDPA and HSUPA Ph1. The HBBI and the NBBIcan be positioned in one baseband subrack.

4.4.2 Operating Environment of the HBBI BoardThe HBBI receives downlink data from the NDTI (or NUTI) or the HDLP (or EDLP) and thensends it to the MTRU after processing. In addition, the HBBI receives uplink data from theMTRU and then sends it to the NDTI (or NUTI) or the HULP (or EULP, EULPd) afterprocessing.

l Processing the digital intermediate frequency signals (on one or two carriers) from theADC, including the down conversion, the filtering extraction, the filtering matching, andDAGC.

l Sends the signals to the interface logic module for framing.

l Executes the RTWP measurement and the correction of the main signals after matchingthe filtering and diverging the signals.

l Reports the result to the CPU.

RF Transceiver

The RF transceiver consists of an RF transmitter and an RF receiver.

The RF transmitter consists of the AQM, the amplifier, the numerically controlled attenuator,the filter, and the digital transmitter.

The RF transmitter has the following functions:

l The digital transmitter outputs one-carrier or two-carrier signals. The signals combinedwith IQ signals are modulated into RF signals in the AQM. The precision of the AQMmodulation can be set to very high by the DPD correction.

l The modulated signals are sent to HPA after amplification, gain adjustment, and filtered.

The RF receiver has the following functions:

l Down converting the uplink signals from the MAFU through filtering to the intermediatefrequency. This intermediate frequency satisfies the ADC processing capabilities.

l The SAW filter filters the signals at this frequency twice to restrain out-of-bandinterference.



4-63

l Because the RX channel is the two-carrier channel, it provides AGC simulation to expendthe dynamic range of the receiver. Therefore, the receiver can reach its highest performanceregardless of the interference.

HPAThe HPA amplifies weak RF signals from the RF transmitter. The maximum output power is38 W or 50 W. It also provides forward coupling for the VSWR test, the DPD feedback and thestabilization of the downlink-gain loop.

Feedback ChannelThe feedback channel converts down the forward TX signals that are coupled by the HPA, andsends to the DPD processing system through the ADC. The DPD compares feedback signalswith input signals in the digital domain to determine the pre-distortion parameter.

CPUThe CPU carries out the control and maintenance inside the MTRU board.

5.5 RF Cables of the BTS3812ERF cables of the BTS3812E consist of the RF jumpers and RF cables between the MTRU andthe MAFU.

5.5.1 RF Cables Between the MTRU and the MAFU of a Macro NodeBThe RF cables between the MTRU and the MAFU have two types: the RF RX signal cable andthe RF TX signal cable. The RF RX signal cable connects the RX port on the MAFU to the RXport on the MTRU and transmits uplink signals. The RF TX signal cable connects the TX porton the MAFU to the TX port on the MTRU and transmits downlink signals.

5.5.2 RF Jumper of the BTS3812ERF jumpers are used to connect the antenna system and the antenna port on the NodeB cabinet.RF jumpers are used for signal interchanges between the NodeB and the antenna system.

5.5.1 RF Cables Between the MTRU and the MAFU of a MacroNodeB

The RF cables between the MTRU and the MAFU have two types: the RF RX signal cable andthe RF TX signal cable. The RF RX signal cable connects the RX port on the MAFU to the RXport on the MTRU and transmits uplink signals. The RF TX signal cable connects the TX porton the MAFU to the TX port on the MTRU and transmits downlink signals.

AppearanceFigure 5-27 shows the RF cable between the MTRU and the MAFU.

l One end of the RF RX signal cable connects the RX port on the MTRU and the other endconnects to the RX port on the corresponding MAFU.

l The RF TX signal cable connects the TX port on the MTRU to the TX port on thecorresponding MAFU.

NOTE

The connection of the RF RX signal cable depends on the configuration of the NodeB. If the configurationis changed, the type of the connection must be changed accordingly.

The Connection of RF Cables Between the MTRU and the MAFU

l The connection of RF cables between the MTRU and the MAFU depends on the NodeBconfiguration. In each configuration, the number of MTRUs is the same as that of MAFUs.Huawei recommends that you connect an MAFU to the MTRU below that MAFU.

l The configuration of the connection of RF cables between the MTRU and the MAFU in 2-way RX and 3–4 carriersIn 2-way RX and 3–4 carrier configuration, two MTRUs and two MAFUs serve one sector.Each sector can be configured with three to four adjacent carriers. In this situation,connectors labeled ANT_TX/RXA at the top of MAFUs are connected to the antenna whileconnectors labeled ANT_RXB are not in use. TX diversity is not supported in thisconfiguration.

NOTE

The NodeB in 2-way RX and 3–4 carrier configuration is also applicable to the 2-way RX and 1–2carrier configuration . In this case, comparing with the 2-way RX and 1–2 carrier configuration, the2-way RX and 3–4 carrier configuration used for 1–2 carrier configuration has higher transmissionpower and supports TX diversity.

Figure 5-28 shows the wiring between RF ports for each sector. The sector operates in 2-way RX and 3–4 carrier configuration.

In 2-way RX and 1–2 carrier configuration, one MTRU and one MAFU serve one sector.Each sector can be configured with two adjacent carriers. In this situation, connectorslabeled ANT_TX/RXA and ANT_RXB at the top of the MAFU are connected to theantenna. TX diversity is not supported in this configuration.Figure 5-29 shows the wiring between RF ports for one sector. The sector operates in 2-way RX and 1–2 carrier configuration.

l The configuration of the connection of RF cables between the MTRU and the MAFU in 4-

way RX and 1–2 carriersIn 4-way RX and 1–2 carrier configuration, two MTRUs and two MAFUs serve one sector.Each sector can be configured with two adjacent carriers. In this situation, connectorslabeled ANT_TX/RXA and ANT_RXB at the top of the MAFU are connected to theantenna. TX diversity is supported in this configuration.Figure 5-30 shows the wiring between RF ports for one sector. The sector operates in 4-way RX and 1–2 carrier configuration.

NOTE

In the previous three configurations, matched loads must be installed on the ports or connectors that arenot in use on the MAFUs to prevent power leakage.

5.5.2 RF Jumper of the BTS3812ERF jumpers are used to connect the antenna system and the antenna port on the NodeB cabinet.RF jumpers are used for signal interchanges between the NodeB and the antenna system.

Structure

Each end of an RF jumper is a DIN male connector, as shown in Figure 5-31.
