Huawei Technologies Co., Ltd. All rights reserved. Page20 Basic Principles In the WCDMA system, all the cells use the same frequency, which is conducive to improve the WCDMA system capacity. However, for reason of co-frequency multiplexing, the system incurs interference between users. This multi- access interference restricts the capacity in turn. The radio system capacity is decided by uplink and downlink. When planning the capacity, we must analyze from both uplink and downlink perspectives.

Huawei Technologies Co., Ltd. All rights reserved. Page22 Interference Analysis Overview Why do we analyze interference in network dimensioning? No matter uplink or downlink dimensioning, the Eb/No requirement should be met: Eb/No = Ec/No × PG Eb/No and PG is pre-defined, so we should calculate expected Ec and No through interference analysis The interference increase which is load factor could be predicted The load factor of each service rate is different

In the static propagation conditions without multi- path, no mutual interference exists.
