ABSTRACT:
A secondary station has a receiver capable of resolving signals received as a plurality of multipath signals from a plurality of base stations during a soft handover process. This capability may, for example, be provided by a Rake receiver. In order to decode and act upon the received signals in a very short period of time, signals (402g,402h) arriving after a predetermined time are not processed by the receiver which is able instead to process weaker signals (402d,402e) which arrived before the time (t1).Such a secondary station is particularly suitable for decoding and acting upon power control commands included in received signals in a UMTS system, for which a very limited period of time is provided by the UMTS specification. In this application the predetermined time (t1) is the time after which signals are received too late for use in determining the next power control change.
