摘要： Provided are a method and apparatus for user equipment (UE) selection in a mobile communication system. The method may include: selecting the n−1th UE in multiple cells (n: constant ≧2); and selecting a UE with the maximum weighted sum rate (WSR) as the nth UE from among UEs belonging to the remaining cells excluding those cells containing the 1st to n−1th UEs. Hence, the scheduling function enabling suitable user equipment selection may further increase overall system throughput by providing additional gains in addition to beamforming, i.e. further reducing inter-cell interference and increasing signal strength toward a desired user equipment.

摘要： One or more embodiments provide an apparatus and a method to estimate channel information even when channel information is not accurately known and design a relay filter based on the estimated information in a two-way relay system where a terminal having a single antenna and a relay exist. A relay apparatus of a two-way relay system includes a receiver, a controller, and a transmitter. The receiver receives a signal from at least one terminal. The controller estimates a channel between the terminals based on the received signal, and calculates a receiver matrix and a precoder. The transmitter transmits a signal precoded by the precoder.
