1. A method of activating semi-persistent scheduling (SPS) in a wireless communication system, the method comprising:
monitoring, by a user equipment (UE), a physical downlink control channel (PDCCH);
obtaining, by the UE, downlink control information (DCI) relating to a Physical Downlink Shared Channel (PDSCH) from the PDCCH,
wherein the DCI includes a new data indicator (NDI) field, a hybrid automatic repeat request (HARQ) process number field and a redundancy version (RV) field; and
activating, by the UE, the SPS based on the HARQ process number field and RV field,
wherein the NDI field consists of 1 bit, the HARQ process number field consists of 4 bits, and the RV field consists of 2 bits,
wherein the activation of the SPS is determined based on whether the 4 bits of the HARQ process number field are set to all zeros and the 2 bits of the RV field are set to all zeros.
