Abstract
A UE, for an HSPA WCDMA system, equipped with a first and a second transmit antenna, and arranged to use one or more sets of pre-coding weights for transmission. The UE is arranged to receive instructions from a NodeB on the set or sets of pre-coding weights to be used, and to transmit 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 uses for transmitting a first data stream, and to use different spreading codes for the first data stream and for the first pilot signal.
