Method and apparatus for transmitting and receiving signal by full-duplex base station in wireless communication system
First Claim
1. A method of transmitting and receiving signals by an IBFD (inband full duplex) base station in a wireless communication system, the method comprising:
- receiving uplink signals, which are repeated K times, in K time intervals, respectively; and
transmitting (K-N) downlink signals in (K-N) time intervals while receiving the uplink signals in the K time intervals,wherein among the K time intervals, the N time intervals are used for cancelling an interference, which one or more user equipments that transmit the uplink signals cause to one or more user equipments that receive the downlink signals, andwherein the cancelling of the interference is performed in such a manner that the one or more user equipments that receive the downlink signals eliminate signal components received in the N time intervals when decoding the (K-N) downlink signals.

Abstract
An embodiment of the present invention relates to a method for transmitting and receiving a signal by an inband full duplex (IBFD) base station in a wireless communication system, comprising the steps of: receiving respective uplink signals that repeat K times in K time intervals; and transmitting K-N downlink signals in K-N time intervals while the uplink signals are received in the K time intervals, wherein the N time intervals in the K time intervals are used for handling interference received by one or more terminals receiving the downlink signals from one or more terminals transmitting the uplink signals.
