The base station 2 controls two or more transmit antenna ports 3a, 3b for supporting a multi-antenna transmission mode and for transmission of data on a channel for communication with a user equipment 4. The method 20 comprises receiving 21 a rank indicator from a user equipment 4, the rank indicator indicating the number of spatial multiplexing layers recommended by the user equipment 4, and determining 22 the transmission rank based on a channel imbalance factor CIF, wherein the channel imbalance factor CIF quantifies a difference in receive power of the two or more transmit antenna ports 3a, 3b. The invention also relates to a base station, methods in user equipment, user equipment, computer programs, and computer program products.

    摘要: The present invention discloses a network node (100) for multi-user scheduling involving retransmission. The network node comprises a receiver (110) adapted to receive channel quality indicator (CQI) report from a user equipment (UE), an adjuster (120) adapted to adjust signal to interference and noise ratio (SINR) derived from the CQI report to obtain SINR for retransmission, a combiner (130) adapted to combine SINR for initial transmission and SINR for one or a plurality of retransmission to obtain effective SINR, and a scheduler (140) adapted to perform multi-user scheduling on the basis of priority metric derived from the effective SINR. The present invention improves multi-user scheduling by taking HARQ combining gain into account. Instantaneous throughput as well as priority metric can be accurately measured, because SINR from not only channel quality (e.g. CQI) but also HARQ processing gain are both included.
