Method and apparatus for receiving or transmitting downlink control signal in wireless communication system
First Claim
1. A method for receiving a downlink signal by a user equipment (UE) in a wireless communication system, comprising:
- receiving a plurality of parameter sets for Semi Persistent Scheduling (SPS)-physical downlink shared channel (PDSCH) through higher layer signaling;
receiving a downlink control information (DCI) configuring the SPS-PDSCH;
determining a parameter set to be used for decoding the SPS-PDSCH among the received plurality of parameter sets based on whether an indicator indicating that the parameter set to be used for decoding the SPS-PDSCH is included in the DCI; and
decoding the SPS-PDSCH using the determined parameter set,wherein the parameter set to be used for decoding the SPS-PDSCH is determined as a predetermined one of the received plurality of parameter sets when the indicator is not included in the DCI.
