HYBRID ZERO-FORCING BEAMFORMING METHOD AND APPARATUS |
摘要 |
Communication methods of a base station and a terminal are provided. The communication method of the base station includes receiving feedback information including ray gain information from a terminal, configuring a Radio Frequency (RF) precoder to minimize a Frobenius norm of a total transmit precoder of the base station, and configuring a baseband precoder based on Zero-Forcing (ZF). The communication method of the terminal includes receiving a pilot signal from a base station; estimating a channel of the terminal using the pilot signal; configuring ray gain information based on information of the estimated channel; and feeding back a codebook index corresponding to the ray gain information to the base station. |
