Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A technique for receiving a downlink control channel is provided that includes operations of determining whether a physical downlink shared channel (PDSCH) is received at a time-domain position n; determining, according to a result of the determining, a frequency-domain position of a bandwidth part (BWP) for receiving a physical downlink control channel (PDCCH) at a time-domain position n+1, and receiving the PDCCH at the BWP of the frequency-domain position. The technique determines the frequency-domain position of the BWP for receiving the PDCCH by determining whether it is necessary to receive the PDSCH at the time-domain position preceding the current time-domain position for receiving the PDCCH, greatly reducing or even eliminating the influence of the adjustment time interval for the user equipment (UE) to convert the BWP on the normal data reception of the UE, which ensures the receiving performance and the throughput level of the received data of the UE.

A method for semi-persistent scheduling (SPS) and an apparatus therefor are provided. The method includes monitoring downlink control information (DCI) in a first format group, and activating SPS according to an indication in the DCI in the first format group, and monitoring DCI in a second format group, and releasing SPS according to an indication in the DCI in the second format group, wherein, the payload size of the DCI format in the second format group is less than the payload size of the DCI format in the first format group.
