Method and apparatus for transmitting and receiving channel related information

摘要

The present disclosure relates to a method and an apparatus for transmitting and receiving channel related information. A method of transmitting channel related information of a UE according to an embodiment of the present disclosure includes configuring a sub-channel corresponding to a part of a plurality of antennas of an eNB; acquiring a Channel Estimation Error (CEE) and a Precoding Matrix Indicator (PMI) corresponding to the sub-channel; and transmitting a Sub-channel Indicator (SI) indicating the sub-channel, according to the CEE and the PMI. In accordance with an embodiment of the present disclosure, the channel related information is efficiently transmitted and received in a system in which a plurality of antennas is used.

1. A method to transmit channel related information using a user equipment (UE), the method comprising:
receiving information related to a sub-channel configuration from an evolved Node B (eNB); receiving a reference signal from the eNB; configuring a sub-channel corresponding to a part of a plurality of antennas of the eNB based on the information; acquiring a channel estimation error (CEE) and a precoding matrix indicator (PMI) corresponding to the configured sub-channel using the reference signal by estimating a correlation between a channel state of the sub-channel and a codebook; and transmitting a sub-channel indicator (SI) indicating a sub-channel that is selected based on the CEE.
