Title: METHOD FOR TRANSMITTING AND RECEIVING DM-RS IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR
Abstract:
Disclosed in the present application is a method by which a terminal receives, from a base station, a downlink signal in a wireless communication system. Particularly, the method comprises the steps of: receiving a downlink control channel from a base station; and receiving a downlink data channel and a slot front-end allocation reference signal for demodulating the downlink data channel by using control information included in the downlink control channel, wherein resource elements of a symbol, in which the slot front-end allocation reference signal is received, are divided into two multiplexing groups or three multiplexing groups, and the downlink control channel includes information on the multiplexing group, to which the slot front-end allocation reference signal is allocated, among the multiplexing groups, and information on the number of the multiplexing groups, to which the data are not allocated, among the multiplexing groups.
