Patent ID: 10700744

Abstract:
A method of receiving a downlink channel, which is received by a user equipment from an eNB in a wireless communication system, is disclosed in the present specification. Specifically, the method includes the steps of receiving a downlink control channel for receiving a DM-RS (demodulation reference signal) based downlink data channel from the eNB, and receiving the DM-RS based downlink data channel using DM-RS configuration information included in the downlink control channel. In this case, if single-codeword transmission via the DM-RS based downlink data channel is indicated by the downlink control channel, the DM-RS based downlink data channel is received using a transmission diversity scheme. If two-codewords transmission via the DM-RS based downlink data channel is indicated by the downlink control channel, the DM-RS based downlink data channel is received using a spatial multiplexing scheme.
