Apparatuses and methods for beamforming in a multiple input multiple output (MIMO) wireless communication system based on hybrid division duplex |
摘要 |
Beamforming in a Multiple Input Multiple Output (MIMO) wireless communication system is provided. An apparatus includes an estimator for estimating a channel matrix of at least one terminal compliant with a Time Division Duplex (TDD) scheme; a processor for confirming information indicative of a channel matrix fed back from at least one terminal compliant with a Frequency Division Duplex (FDD) scheme; and a controller for determining precoding vectors or terminals to be connected in a spatial multiple access manner, using the channel matrix of the at least one terminal compliant with the TDD scheme and a principal vector of the at least one terminal compliant with the FDD scheme.
