DEVICE AND METHOD FOR HSPA WCDMA UPLINK PILOTS

摘要

A UE (115), for an HSPA WCDMA system (100), equipped with a first (111) and a second (112) transmit antenna, and arranged (15, 17) to use one or more sets of pre-coding weights for transmission. The UE (115) is arranged to receive (14) instructions from a NodeB (105) on the set or sets of pre- coding weights to be used, and to transmit (16) a first and a second pilot signal, and to use a first set of pre-coding weights for the first pilot signal and a second set of pre-coding weights for the second pilot signal, where the first set of pre-coding weights is the same as the UE (115) uses for transmitting a first data stream, and to use different spreading codes for the first data stream and for the first pilot signal.
