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.
