摘要： An apparatus and method for reducing differential cross-talk in a pin arrangement of a socket are described. Socket pins within a differential pair use a modified shape to tighten the intra-pair pin coupling to reduce the crosstalk without changing the pin map. The middle vertical segment of one pin of a diagonally adjacent differential pin pair is modified to be closer to the other pin than other corresponding locations of the pins. The spring beam that extends from the middle vertical segment of the one pin is modified to accommodate the package landing pad that the spring beam contacts to maintain a uniform pitch.

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.
