An operation method, associated with uplink, UL, transmission, by a terminal in a wireless communication system supporting dynamic resource sharing between eMBB and URLLC, the method comprising: receiving, from a base station, a UL grant for scheduling an uplink resource for the uplink transmission, the uplink transmission being eMBB; receiving, from the base station, downlink control information for cancellation of the uplink transmission on the scheduled uplink resource, wherein the downlink control information includes information on the scheduled uplink resource for which the uplink transmission is to be cancelled; and determining, whether the downlink control information for the cancellation of the uplink transmission on the scheduled uplink resource is valid, based on whether a value which is 1) a value of a time interval between i) a timing when the terminal receives the downlink control information for the cancellation of the uplink transmission on the scheduled uplink resource and ii) a starting timing of the scheduled uplink resource minus 2) a value of timing advance, TA, related with the terminal is less than a value based on processing capability of the terminal, wherein based on the downlink control information for the cancellation of the uplink transmission on the scheduled uplink resource being valid, the uplink transmission on the scheduled uplink resource is canceled, wherein based on the downlink control information for the cancellation of the uplink transmission on the scheduled uplink resource being invalid, the uplink transmission on the scheduled uplink resource is performed, wherein based on that the value which is 1) the value of the time interval between i) the timing when the terminal receives the downlink control information for the cancellation of the uplink transmission on the scheduled uplink resource and ii) the starting timing of the scheduled uplink resource minus 2) the value of the TA related with the terminal is less than the value based on the processing capability of the terminal, the downlink control information for the cancellation of the uplink transmission on the scheduled uplink resource is invalid, and wherein based on that the value which is 1) the value of the time interval between i) the timing when the terminal receives the downlink control information for the cancellation of the uplink transmission on the scheduled uplink resource and ii) the starting timing of the scheduled uplink resource minus 2) the value of the TA related with the terminal is equal or greater than the value based on the processing capability of the terminal, the downlink control information for the cancellation of the uplink transmission on the scheduled uplink resource is valid. receiving, from a base station, a UL grant for scheduling an uplink resource for the uplink transmission, the uplink transmission being eMBB;
