Overview

In BBU Interconnection, two BBUs are connected using a BBU interconnection signal cable. The BBU Interconnection feature applies to the following scenarios: l

Triple-mode base station deployment With BBU Interconnection, a base station can be deployed in the following modes: GU+L, GL+U, or G*U*L+G*U*L. Two interconnected BBUs belong to the same base station.

l

UMTS baseband capacity expansion A single BBU supports a maximum of 6 UMTS baseband boards. BBU Interconnection enables two BBUs to support a maximum of 11 UMTS baseband boards, enhancing the UMTS baseband capacity of a base station. SRAN9.0 supports UMTS baseband interconnection only. NOTE

Unless otherwise specified, the BBU in this document refers to both the BBU3900 and BBU3910.

BBU3900 +BBU3910; BBU3910 +BBU3910;

In the connected BBUs shown in Figure 2-2, BBU 0 and BBU 1 are the root BBU and leaf BBU, respectively. The root BBU and leaf BBU are determined in the site hardware planning. You can identify whether a BBU serves as the root BBU or leaf BBU by using the following methods: l

In the UCIU+UMPT interconnection, the BBU configured with a UCIU is the root BBU.

l

In the UMPT+UMPT interconnection, the BBU at the end with the Master color-coding on the BBU interconnection signal cable is the root BBU. Fiber optic cables cannot connect BBUs in this interconnection method.

A BBU interconnection signal cable is logically called CTRLLNK for an eGBTS, a NodeB or an eNodeB and is logically called BTSCTRLLNK for a GBTS. By default, leaf BBU is the local node and root BBU is the upper-level node of a CTRLLNK or BTSCTRLLNK. In UCIU+UMPT interconnection, SingleRAN10.0 supports a maximum of two CTRLLNKs for a NodeB or an eNodeB and two BTSCTRLLNKs for a GBTS. In UMPT+UMPT interconnection, SingleRAN10.0 supports only one CTRLLNK for an eGBTS, a NodeB or an eNodeB and one BTSCTRLLNK for a GBTS.

NOTE

l In a co-MPT base station where two BBUs are interconnected, the primary and secondary main control boards are configured in BBU 0 and BBU 1, respectively. The modes configured in BBU 1 must also be configured in BBU 0. l In triple-mode base stations, a board of a certain mode must be configured in the same BBU as the main control board of this mode. For details about the board configurations for each mode, see the BBU Hardware Description.

2.2.4 Restrictions When UCIU+UMPT interconnection is used in a triple-mode base station, the following restrictions apply: l

GSM boards must be installed in BBU 0.

l

Monitoring devices must be connected to BBU 0.

l

Boards in the same BBU must have the same cabinet and subrack numbers. Boards in different BBUs must have different cabinet numbers or both different cabinet and subrack numbers. Otherwise, common boards, such as the UCIU, cannot function.

l

A BBU3910 cannot be configured with a UCIU.

l

If two interconnected BBU subracks work in co-MPT multiple modes or in single mode, the primary BBU subrack must provide transmission ports.

When UMPT+UMPT interconnection is used in a triple-mode base station, the following restrictions apply in addition to the preceding restrictions: l

The distance between BBU 0 and BBU 1 must be less than or equal to 5 m.

l

BBU 1 must be configured with a UMPTb.

l

If BBU 0 is configured with the GTMU, WMPT, or LMPT, cascaded RRUs cannot be connected to BBU 1.

l

Only BBU interconnection signal cables provided by Huawei can be used. Fiber optic cables cannot be used.

l

Transmission cables must be connected to BBU 0. NOTE

In the UMPT+UMPT interconnection and only one UMPT connects to external transmission equipment scenario, if the transmission cable is removed from the original UMPT and reconnected to the other UMPT, you need to reset the later UMPT by pressing the reset button on the UMPT or removing and reinserting the UMPT.

2 Overview

2.2.5 Supported Features and Functions In a triple-mode base station, two BBUs are connected using a BBU interconnection signal cable. The BBUs exchange control data, transmission data, and clock signals. Therefore, the BBUs support common transmission (co-transmission), inter-BBU software-defined radio (SDR), and a common clock.

Supported Features l

Co-Transmission

When two BBUs are interconnected, the BBUs support co-transmission between two or more modes. For details, see Common Transmission Feature Parameter Description. l

Common Clock

When two BBUs are interconnected, the BBUs support a common clock between two or more modes. For details, see Common Clock Feature Parameter Description. l

Inter-BBU SDR

In inter-BBU SDR, a multimode RF module is connected to both BBUs. Figure 2-3 shows an example of inter-BBU SDR in which BBU 0 supports GSM and BBU 1 supports LTE. The RXU (GL) is connected to both BBU 0 and BBU 1. Figure 2-3 Inter-BBU SDR

NOTE

RXU refers to RRU and RFU.

Inter-BBU SDR clock signals for the secondary BBU must be synchronized with those for the primary BBU. The clock signal synchronization mode is selected according to the following rules: l

If the primary BBU uses frequency synchronization, the secondary BBU must use frequency synchronization.

l

If the primary BBU uses time synchronization, the secondary BBU can use either time or frequency synchronization.

2.3 UMTS Baseband Capacity Expansion Issue Draft B (2014-07-30)

2 Overview

2.3.1 Cable Connections In a triple-mode base station using BBU Interconnection, the WBBPf boards or UBBPd boards in the BBUs can be interconnected to exchange baseband data. Figure 2-4 shows the inter-BBU cable connections for UMTS baseband capacity expansion. Figure 2-4 Inter-BBU cable connections for UMTS baseband capacity expansion

A UMTS baseband board and a UMTS main control board are installed in both BBU 0 and BBU 1, and the two UMTS baseband boards are interconnected using a BBU interconnection signal cable. Among UMTS baseband boards, WBBPf boards and UBBPd boards can provide HEI ports for UMTS baseband interconnection. A WBBPf board or UBBPd board can be installed only in slot 2 or slot 3 (preferred) in either BBU. A BBU interconnection signal cable between WBBPf boards transmits baseband data and expands baseband resources. A BBU interconnection signal cable between WBBPf boards cannot be used interchangeably with that for UCIU+UMPT or UMPT+UMPT interconnection. A BBU baseband interconnection signal cable is logically called BBPLNK. Either end of a BBPLNK can be configured as the link head. It is recommended that you configure the end on the BBU 0 side as the link head. SRAN10.0 supports only one BBPLNK.

5.3.2 Subracks and Hardware Configurations for the BBUs For the installation locations and hardware configurations of BBU 0 and BBU 1 in each cabinet when a new multimode base station is deployed, see 3900 Series Base Station Hardware Description. In UCIU+UMPT interconnection, the UCIU is controlled by only one single-mode main control board. Otherwise, ALM-26274 Inter-System Board Object Configuration Conflict is reported. UCIU-related alarms are reported only to the single-mode main control board controlling the UCIU. When deploying a new Multimode base station, you are advised to comply with the following rules to set the control mode for the UCIU: l

In UMTS baseband capacity expansion scenarios, UMTS is preferred to control the UCIU.

l

In other scenarios, the mode priority descends from GSM, to UMTS, and then to LTE.

l

In capacity expansion scenarios, it is recommended that the controlling mode of the UCIU remain unchanged. Alternatively, you can modify the controlling mode based on information provided in Table 5-2.

Table 5-2 lists the mode recommended for controlling the UCIU in each scenario. Table 5-2 Mode recommended for controlling the UCIU in each scenario Mode

During new Multimode base station deployment, the mode deployment order remains unchanged no matter whether the mode controlling the UCIU is first deployed. However, it is recommended that the mode controlling the UCIU be first deployed. By doing this, UCIU-related alarms can be reported in time.

5.3.3 Transmission Modes With BBU Interconnection, a base station supports the following: l

Independent transmission

l

Inter-BBU co-transmission



14



Independent Transmission In a triple-mode base station deployment scenario, each mode is connected to the transport network through its own port and is deployed in the same way as that in a single-mode base station. In UMTS baseband capacity expansion scenarios, both BBUs have a UMTS main control board, and either BBU can be connected to the RNC through the Iub interface. However, it is recommended that BBU 0 be connected to the RNC.

Inter-BBU Co-Transmission For engineering guidelines about co-transmission, see Common Transmission Feature Parameter Description. A multimode base station supports the following co-transmission modes to implement inter-BBU co-transmission: l

UMPT-based co-transmission through backplane interconnection All modes except the one controlling the UMPT send their data to the UMPT through BBU backplanes and BBU interconnection signal cables. The co-transmission port on the UMPT is connected to the transport network, and the link between the port and transport network carries data of all the modes in the multimode base station. When deploying a multimode base station, first deploy the mode controlling the UMPT. Otherwise, other modes cannot be deployed.

l

UTRPc-based co-transmission through backplane interconnection All modes send their data to the UTRPc through BBU backplanes and BBU interconnection signal cables. The co-transmission port on the UTRPc is connected to the transport network, and the link between the port and transport network carries data of all the modes in the multimode base station. When deploying a multimode base station, first deploy the mode controlling the UTRPc. Otherwise, other modes cannot be deployed.

In new multimode base station deployment scenarios, the UTRPc has the following configuration restrictions: l

The UTRPc can be controlled by only one mode whose main control board is installed in the same BBU as the UTRPc.

l

When deploying a new multimode base station, it is recommended that you deploy the control mode of a UTRPc following a priority descending from LTE, to UMTS, and then to GSM. By default, the UTRPc is controlled by UMTS before delivery.

Table 5-3 lists the mode recommended for controlling the UTRPc and the related mode deployment order when an Multimode base station works in different modes.

5.3.4 CPRI-based Topologies With Single-Mode RF Modules If single-mode RF modules are configured, chain, ring, and star topologies are supported. For UMTS baseband expansion, the ring topology is not supported between two BBUs, as shown in Figure 5-1.



17



Figure 5-1 Ring topology not supported between two BBUs

In UMPT+UMPT interconnection, only the star topology is supported for BBU 1 when the BBU 0 is configured with the GTMU, WMPT, or LMPT, as shown in Figure 5-2.



18



Figure 5-2 Ring topology not supported between two BBUs

With Multi-Mode RF Modules If multi-mode RF modules are configured, a dual-star topology must be used to achieve interBBU SDR. Figure 5-3 and Figure 5-4 show two dual-star topology examples with GU RFUs and GU RRUs, respectively.

NOTE

For details about the CPRI-based topologies and specifications of CRPI ports, see RF Unit and Topology Management Feature Parameter Description and CPRI MUX Feature Parameter Description.

5.3.5 Clocks With BBU Interconnection, a base station uses one of the following clocks: l

Independent reference clock

l

Common reference clock

Independent Reference Clock In triple-mode base station deployment scenarios, the reference clock for each mode is the same as that in a single-mode base station. WBBPfIn UMTS baseband capacity expansion scenarios, both BBU 0 and BBU 1 have a WBBPf. The reference clock can be configured in either BBU.

Common Reference Clock The common reference clock can be configured in either BBU 0 or BBU 1. The BBU configured with the common reference clock shares control data and clock signals with the other BBU through a BBU interconnection signal cable and the BBU backplane. For engineering guidelines about the common reference clock, see Common Reference Clock Parameter Description.

5.4 Feature Deployment 5.4.1 Deployment Requirements None.

5.4.2 Data Preparation Upgrade to Triple-Mode Base Stations Perform the following steps to plan the data: Step 1 Designate BBU0 and BBU1. Plan the cabinet number and subrack number for each BBU. If BBU0 and BBU1 are configured in the same cabinet, their subrack numbers must be different. If they are configured in different cabinets, their subrack numbers can be the same. Step 2 Plan the control links. ----End The control link is logically CTRLLNK for NodeB or eNodeB, and BTSCTRLLNK for GBTS. Physically, the control link is the BBU interconnection signal cable between the UCIU and UMPT. Issue Draft B (2014-07-30)


21



The two ends of each CTRLLNK/BTSCTRLLNK must be designated. By default, BBU1 is the local node and BBU0 is the upper-level node. The number of each CTRLLNK/BTSCTRLLNK for the base station must be unique. The link numbers of all the CTRLLNKs/BTSCTRLLNKs need to be planned. A CTRLLNK/BTSCTRLLNK needs to be added for each mode of the base station. Table 5-4 Parameters for CTRLLNK and BTSCTRLLNK Parameter Name

UMTS Baseband Capacity Expansion Perform the following steps to plan the data: Step 1 Designate BBU0 and BBU1. Plan the cabinet number and subrack number for each BBU. If BBU0 and BBU1 are configured in the same cabinet, their subrack numbers must be different. If they are configured in different cabinets, their subrack numbers can be the same. Step 2 Plan the control links. For details, see 2.2 Upgrade to Triple-Mode Base Stations. Step 3 Plan the baseband processing link. ----End The baseband processing link is logically BBPLNK. Physically, the baseband processing link is the BBU interconnection signal cable between WBBPf boards. The two ends of the BBPLNK must be designated. Either end of a BBPLNK can be configured as the link head. It is recommended that you configure the end on the BBU 0 side as the link head. The default port number of the link head or tail is 6. The number of the BBPLNK needs to be planned. Only one BBPLNK is supported in SingleRAN9.0.

Step 2 Check the status of the HEI indicator on the WBBPf to determine whether BBPLNK is operating correctly. If the HEI indicator is green, BBPLNK is operating correctly. ----End NOTE

Mx can be the M0, M1, M2, M3, or M4 port on the UCIU.

At the Remote End l

On the U2000 device panel, you can query the master/slave indication of the BBU interconnection cable to check whether the cable is correctly connected. The yellow end is the master port.

l

On the U2000 maintenance console or the LMT, you can run the LST CTRLLNK/ BTSCTRLLNK command to query the cabinet number, subrack number, slot number, and port number at both ends of the BBU interconnection signal cable.

l

Run the MML command DSP CTRLLNKSTAT/BTSCTRLLNKSTAT to check whether CTRLLNK/BTSCTRLLNK is operating correctly.

l

Run the MML command DSP BBPLNK command to check whether BBPLNK is configured as planned.
