METHOD AND APPARATUS FOR CHANNEL INFORMATION FEEDBACK IN A WIRELESS COMMUNICATION SYSTEM

摘要

Provided are a method and apparatus for channel information feedback in a wireless communication system. A terminal may receive CSI-RS configuration information from a base station and generate channel information using a codebook determined in accordance with the number of CSI-RS patterns set by the CSI-RS configuration information. The base station may transmit CSI-RS patterns allocated to a plurality of nodes through a method for expanding a field within one control message.
