A user equipment, UE, (300), a radio base station, RBS, (400) and a respective method (100) and (200) therein for joint transmit and receive procedure are provided. The method (100) in the UE comprises receiving (110) at a time slot n, a first transmission from the RBS, the transmission comprising a first pre-coded symbol; and estimating (120) a real channel referring to a transfer function of the channel and an effective channel referring to the real channel adjusted by transmission weights for the received first transmission. The method further comprises determining (130) a combining vector based on the effective channel, and determining (140) a feedback vector based on the combining vector and the real channel. The method comprises transmitting (150) the feedback vector to the RBS, to be used by the RBS for determining an SLNR pre-coding vector for a second transmission to the UE in a subsequent time slot. |
