Terminal operation method in accordance with uplink sps in wireless communication system and terminal using same

A user equipment (UE) configured to perform uplink semi-persistent scheduling (SPS) in a wireless communication system, the UE comprising:

• a transceiver;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
• receiving, via the transceiver and from a base station, downlink control information (DCI) that has a DCI format 0 and that instructs activation of the uplink SPS;
• determining whether the DCI is decodable using a first radio network temporary identifier (RNTI);
• based on a determination that the DCI is decodable using the first RNTI:
• determining that the DCI comprises an index of an uplink SPS configuration;
• and
• based on a determination that the DCI is not decodable using the first RNTI:
• determining that the DCI comprises a cyclic shift value for a demodulation-reference signal (DM-RS).
