Title:
METHOD FOR TRANSMITTING OR RECEIVING SIGNAL TO OR FROM USER EQUIPMENT BY BASE STATION SUPPORTING FULL DUPLEX IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/139423
Kind Code:
A1
Abstract:
An embodiment of the present invention provides a method for transmitting or receiving a full duplex signal to or from a user equipment (UE) by a base station supporting full duplex in a wireless communication system, the method comprising the steps of: transmitting, by the base station, a first RE set including two REs to the UE while applying different pre-coders to the two REs of the first RE set; and receiving a second RE set including two REs from a plurality of UEs including the UE while applying different post-coders to the two REs of the second RE set during the transmission of the first RE set, wherein a code division multiplexing (CDM) code is applied to each of the first RE set in which the base station performs downlink transmission to the UE and the second RE set in which the UE performs uplink transmission to the base station.
