Claim 4:
5. A method performed by a terminal in a wireless communication system, the method comprising:
monitoring control information;
identifying a cyclic redundancy check (CRC) of the control information and a new data indicator (NDI) field in the control information, in case that an uplink (UL) grant type 2 is configured for a scheduling cell, wherein the control information includes a carrier indicator field corresponding to the scheduling cell;
identifying whether the UL grant type 2 is released for the scheduling cell based on special fields in the control information, in case that the CRC of the control information is scrambled with a configured scheduling-radio network temporary identifier (CS-RNTI) and the NDI field in the control information is set to 0; and
releasing the UL grant type 2 for the scheduling cell, based on the special fields being set to predetermined values,
wherein the control information is based on a downlink control information (DCI) format 0_1 or a DCI format 1_1.
