Method of measuring self-interference channel and user equipment thereto
First Claim
1. A method of supporting measurement of a self-interference channel in a user equipment in a full duplex radio, FDR, communication environment, the method comprising:
- receiving, from a base station, resource allocation information comprising at least one of information about a time interval and information about a frequency band;
transmitting a first reference signal for measurement of the self-interference channel over a wireless channel in accordance with the resource allocation information; and
receiving a second reference signal in accordance with the resource allocation information, the second reference signal being input to a receiver of the user equipment according to self-interference,wherein the time interval is a time interval in which the base station stops transmission of a signal for measurement of the self-interference channel in the user equipment, andwherein the second reference signal is a signal corresponding to the first reference signal transmitted over a wireless channel.

Abstract
A method of measuring a self-interference channel in user equipment in a full duplex radio (FDR) communication environment is disclosed. The method includes receiving, from a base station, resource allocation information including information about a time interval, the base station stopping transmission of a signal in the time interval for measurement of the self-interference channel in the user equipment, transmitting a first reference signal for measurement of the self-interference channel in the time interval specified by the resource allocation information, and receiving a second reference signal input to a receiver of the user equipment according to self-interference in the time interval, wherein the second reference signal is a signal corresponding to the first reference signal transmitted over a wireless channel.

8. A user equipment for supporting measurement of a self-interference channel in a full duplex radio (FDR) communication environment, comprising:
-
a transmitter; a receiver; and a processor connected to the transmitter and the receiver to measure the self-interference channel, wherein the processor is configured to; control the receiver to receive, from a base station, resource allocation information comprising at least one of information about a time interval and information about a frequency band, control the transmitter to transmit a first reference signal for measurement of the self-interference channel over a wireless channel in accordance with the resource allocation information, and control the receiver to receive a second reference signal in accordance with the resource allocation information, the second reference signal being input to a receiver of the user equipment according to self-interference, wherein the time interval is a time interval in which the base station stops transmission of a signal for measurement of the self-interference channel in the user equipment, and wherein the second reference signal is a signal corresponding to the first reference signal transmitted over a wireless channel. - View Dependent Claims (9, 10, 11, 12, 13)
