er needed (better capacity); Both RT (real time) and NRT (nonreal time) RABs are supported; Intrafrequency HO is divided in to soft handover (SHO), and softer handover (SfHO), which can be made simultaneously. Softer Handover (SfHO) A special case of soft handover is softer handover, where the UE is connected to two or more sectors from the same WBTS. There are different scrambling codes used for each DL radio link transmission. In the UL the RAKE receiver is used to combine signals from two sectors; thus additional RAKE receiver channels need to be allocated. The WBTS combines the signals and no extra transmission across lub (WBTS-RNC) is needed. However, in downlink two or more sectors are transmitting and the mobile needs to allocate resources for each radio link. The power control function has only one power control loop active in the case of softer handover. The same power control command is sent in all softer handover radio links. This is different from SHO where each DL radio link (DPCCH) transmits power control commands independently. The SfHO requires additional channelisation codes as well as additional DL transmission power. Softer handover occurs in 5-15% of the network area. As a planning tool it is easy to spot softer handover areas and there is clear-cut dominance in areas between sectors within the same Node B. If SHO areas are visualised the areas between the sectors are where SfHO occurs. Parameter Planning SHO Process The soft handover process controls triggering conditions. A triggering condition is the measured Ec/10. If it becomes lower than the defined threshold, the triggering conditions are true. There is also a mechanism called 'time to trigger', which is a time that triggering conditions need to be true before the UE sends a reporting event. A reporting event tells which cell has triggered an event. In the same measurement message the UE also sends measurement results from other measured cells to the RNC. When the RNC receives a reporting event, it allocates/removes an SHO connection if
