摘要： A method for configuring communication in a wireless communication system includes obtaining, at a first network node, information indicating a plurality of candidate subframes for downlink transmissions to a wireless communication device in a first cell served by the first network node. Each candidate subframe satisfies a candidate condition that relates to transmissions in a second cell during that subframe. The method also includes determining, based on the obtained information, a number of copies of an uplink transmission a wireless communication device should transmit in consecutive uplink subframes so that a downlink transmission related to the uplink transmission will occur during one of the candidate subframes. Additionally, the method includes configuring the wireless communication device to transmit the determined number of copies of the uplink transmission in consecutive subframes.

摘要： According to the disclosure, there is provided a method for the UE to mitigate Cell-specific Reference Signal (CRS) interference (not only the other interference cells' CRS interference but also the serving cell's CRS interference) during ePDCCH/PDSCH demodulation. In one non-limiting embodiment, a CRS interference mitigation method may include steps of: determining CRS having been configured is not serving cell's CRS; and mitigating interference originating from the serving cell's CRS by referring to serving cell's CRS configuration. The present disclosure also relates to a UE for implementing the above CRS interference mitigation method.

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.
