Claim of US Patent No. 10,798,728

1. A method for transmitting an uplink signal by a user equipment in a wireless communication system, the method comprising:receiving, from a base station, downlink control information (DCI) scheduling the uplink signal, wherein the DCI comprises channel sensing operation type information and information related to an uplink signal transmission period, and
wherein the channel sensing operation type information indicates one of a plurality of predetermined channel sensing operation types;
based on that the channel sensing operation type information indicates a first type channel sensing operation:
performing the first type channel sensing operation; and
based on the first type channel sensing operation, transmitting, to the base station, the uplink signal in the uplink signal transmission period;
based on that the channel sensing operation type information indicates a second type channel sensing operation:
performing the second type channel sensing operation; and
based on the second type channel sensing operation, transmitting, to the base station, the uplink signal in the uplink signal transmission period,
wherein the channel sensing operation type information comprises at least one bit,
wherein one of the plurality of predetermined channel sensing operation types is indicated based on the at least one bit,
wherein the at least one bit with a first value is mapped to the first type channel sensing operation, and
wherein the at least one bit with a second value is mapped to the second type channel sensing operation.
