Secondary station and method of operating the station
First Claim
1. A secondary station for use in a radio communication system comprising a plurality of primary stations, the secondary station comprising a processor configured to:
- communicate simultaneously with at least two primary stations,resolve transmitted signals from the at least two primary stations received by a receiver of the secondary station as a plurality of multipath signals, anddetermine whether to allocate each multipath signal to the receiver based on whether its time of arrival occurs within a window of arrival.

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 arriving after a predetermined time are not processed by the receiver which is able instead to process weaker signals which arrived before the time. 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. The predetermined time may be the time after which signals are received too late for use in determining the next power control change.
