METHOD FOR RECEIVING DOWNLINK SIGNAL IN MULTI-ANTENNA WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR |
摘要 |
Disclosed in a method for a terminal to receive a downlink signal in a multi user MIMO (MU-MIMO) wireless communication system. More specifically, the method comprises the steps of: receiving downlink control information (DCI) from a base station; obtaining a parameter for a downlink demodulating-reference signal (DM-RS) included in the downlink control information; receiving the downlink DM-RS specified to the terminal on the basis of the parameter; and receiving a downlink data signal on the basis of the downlink DM-RS specified in the terminal, wherein the parameter includes information on a rank which is set in the terminal and a logical antenna port in which the downlink DM-RS is defined. |
