1. A method performed by a user equipment in a wireless communication system, the method comprising:
receiving a physical downlink control channel (PDCCH) including downlink control information (DCI) format from a base station,
wherein the DCI format includes a frequency domain resource assignment (FDRA) field, a modulation and coding scheme (MCS) field, and a redundancy version (RV) field,
wherein, when multiple semi-persistent scheduling physical downlink shared channel (SPS PDSCH) configurations are provided, the use of the DCI format to release some or all of the multiple SPS PDSCH configurations is determined based on a value of the FDRA field according to a FDRA type; and
releasing the some or all of the multiple SPS PDSCH configurations based on the DCI format when the multiple SPS PDSCH configurations are provided and the DCI format is used to release the some or all of the multiple SPS PDSCH configurations;
wherein the use of the DCI format to release the some or all of the multiple SPS PDSCH configurations is determined depending on whether all bits of the FDRA field are set to ‘0’ when a dynamic switch is configured in which the FDRA type is determined according to a value of a most significant bit (MSB) of the FDRA field.
