METHOD OF TRANSCEIVING FEEDBACK INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

摘要

According to one embodiment of the present invention, a method of transmitting feedback information by a base station supporting multi-user multi-input multi-output (MU-MIMO) to a network entity includes obtaining a projection matrix based on channel information estimated for multiple channels between antennas of the base station and each of user equipments, projecting at least one of the channel information and uplink data received from the user equipments to a second space from a first space using the projection matrix and transmitting feedback information including at least one of the projected channel information and the projected uplink data to the network entity.
