Title:
METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM USING MULTIPLE ANTENNAS
Document Type and Number:
WIPO Patent Application WO/2017/086753
Kind Code:
A1
Abstract:
The present invention relates to a method and a device for efficiently transmitting and receiving a periodic channel state report in a wireless communication system supporting multiple antennas, and according to an embodiment of the present invention, a method by which a terminal transmits channel state information comprises the steps of: receiving, from a base station, first configuration information on at least one reference signal; receiving second configuration information for generating periodic channel state information according to the measurement of the at least one reference signal; receiving, from the base station, and measuring the at least one reference signal on the basis of the first configuration information; and generating the periodic channel state information including a first precoding matrix indicator (PMI) for a wideband so as to transmit the generated periodic channel state information to the base station, on the basis of the second configuration information including configuration information for a channel state report in a subband.
