Method for terminal for transmitting uplink data in FDR communication environment
First Claim
1. A method of transmitting uplink data by a UE in a full duplex radio (FDR) communication environment, comprising:
- determining an overlap region corresponding to a resource region of a downlink control channel received from a base station (BS) during FDR communication with the BS, from among resource regions for transmission of an uplink data channel;
mitigating an influence of self-interference caused by uplink communication on the overlap region; and
transmitting the uplink data channel through the overlap region in which the influence of self-interference has been mitigated and a region other than the overlap region, from among the resource regions for transmission of the uplink data channel,wherein the mitigating of self-interference comprises adjusting a modulation and coding scheme (MCS) level with respect to the overlap region in consideration of an effective signal-to-interference-and-noise ratio (SINR) determined on the basis of the following Equation,

Abstract
Disclosed are a method and a terminal for transmitting data, the method comprising the steps of: determining, during FDR communication with a base station, an overlap region from among a resource region for transmitting an uplink data channel, the overlap region being the resource region for a downlink control channel received from the base station; mitigating the effects of self-interference in the overlap region due to an uplink communication; and transmitting the uplink data channel by means of the overlap region for which the effects of self-interference have been mitigated and the region excluding the overlap region from among the resource region for transmitting the uplink data channel.

10. A UE for transmitting uplink data in a full duplex radio (FDR) communication environment, the UE comprising:
-
a transmitter; a receiver; and a processor connected to the transmitter and the receiver to transmit uplink data, wherein the processor; determines an overlap region corresponding to a resource region of a downlink control channel received from a base station (BS) during FDR communication with the BS, from among resource regions for transmission of an uplink data channel; mitigates an influence of self-interference caused by uplink communication on the overlap region; and controls the transmitter to transmit the uplink data channel through the overlap region in which the influence of self-interference has been mitigated and a region other than the overlap region, from among the resource regions for transmission of the uplink data channel, wherein the mitigation of self-interference comprises adjusting a modulation and coding scheme (MCS) level with respect to the overlap region in consideration of an effective signal-to-interference-and-noise ratio (SINR) determined on the basis of the following Equation,
