Title:
PRE-CODING METHOD FOR REMOVING INTERFERENCE IN FULL DUPLEX COMMUNICATION, AND BASE STATION AND USER TERMINAL FOR PERFORMING SAME
Document Type and Number:
WIPO Patent Application WO/2018/143716
Kind Code:
A1
Abstract:
Disclosed are a pre-coding method for removing interference in full duplex communication, and a base station performing same. The disclosed base station, which is a full duplex-type base station for removing signal interference between half duplex-type an uplink terminal and a downlink terminal, includes: a channel estimation unit which estimates channel coefficients between the base station, uplink terminal and downlink terminal; a reception precoding matrix generation unit which generates a reception precoding matrix on the basis of a first code and a channel with the uplink terminal; and a transmission precoding matrix generation unit which generates a transmission precoding matrix on the basis of a second code that is orthogonal to the first code, and a channel with the downlink terminal, wherein the base station is characterized in that the first code is used for generating a transmission signal of the uplink terminal, the second code is used for removing the transmission signal—including the first code—of the uplink terminal, which is received as an interference signal at the time the downlink terminal receives a signal from the base station. According to the disclosed base station, in a system including the full duplex-type base station and the half duplex-type user terminal, interference between an uplink terminal and a downlink terminal can be efficiently removed.
