Product Description Part 2

RBS 210 6 and RBS 2206Radio Configurations

• The configurations have TRX c onnected to different antennas in the same

antenna system.

One possible application using SPB together with hybrid c ombiner is creating

overlaid and underlaid cells during cell planni ng, as described below:

1 One underlaid cell consists of the second TRX in the first dTRU and the

first TRX in the second dTRU. SPB is used in this cell.

2 One overlaid cell consists of the two other TRXs. SPB is not used in this

cell.

6.4 Transmitter Coher ent Comb ining (TCC) Configuratio ns with CDU-G

This section specifies which configurations support Transmitter Coherent

Combining (TCC). The section do es not include any additional site cell

configurations.

A minimum of two TRXs is required in order to support TCC.

TCC with CDU-G Configurations with Hybrid Combiner

TCC is supported in all of the SCCs with CDU-G, specified in Section 6 Site

Cell Configurations (SCC) on page 41, which fulfill the following condition s:

• The configurations use hybrid combiner.

• The configurations have two TRXs w ithin the same dTRU.

7 Co-Siting with RBS 200 or RBS 2000 M acro Cabi nets

This section shows expansions where RBSs, forming an original SCC, are

co-s ited and use TG-synchronisation to form one new resulting SCC. Anten nas

are not shared.
