CODEBOOK-BASED SIGNAL TRANSMISSION AND RECEPTION METHOD IN MULTI-ANTENNA WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR |
摘要 |
Disclosed are a codebook-based signal transmission and reception method in a multi-antenna wireless communication system and an apparatus therefor. Specifically, a method for transmitting or receiving a signal on the basis of a codebook by a terminal in a 2-dimensional multi-antenna wireless communication system comprises the steps of: receiving a channel state information reference signal (CSI-RS) through a multi-antenna port from a base station; and reporting channel state information to the base station, wherein the channel state information may include a precoding matrix indicator (PMI) for indicating a precoding matrix, the PMI may include a first PMI for selecting a set of precoding matrixes from the codebook and a second PMI for selecting one precoding matrix from the set of precoding matrixes. |
