1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station (BS) via a higher layer signaling, configuration information on at least one configured grant (CG) to be deactivated among a plurality of CGs;
receiving, from the BS, downlink control information (DCI) including a hybrid automatic repeat and request (HARQ) process number field, wherein a value of the HARQ process number field corresponds to the at least one CG to be deactivated; and
transmitting, to the BS, a medium access control (MAC) control element (CE) for confirming the at least one CG,
wherein the MAC CE includes a bitmap comprising one or more a number of bits corresponding to the at least one CG,
wherein a subheader of the MAC CE includes a logical channel identifier (LCID) value indicating the MAC CE for confirming the at least one CG,
wherein all of a redundancy version field, a modulation and coding scheme field, and a frequency domain resource assignment field included in the DCI are used to validate the DCI, and
wherein the HARQ process number field in the DCI is not used to validate the DCI.
