1. An operation method of a terminal in a communication system, the operation method comprising:
receiving a first downlink control information (DCI) including resource allocation information of a first physical downlink shared channel (PDSCH) from a base station;
when a resource region of the first PDSCH indicated by the first DCI overlaps with a resource region of a physical downlink control channel (PDCCH) candidate, and a number of overlapping resource elements between the resource region of the first PDSCH and the resource region of the PDCCH candidate is below a threshold, performing a blind decoding operation for obtaining a second DCI from the PDCCH candidate;
when the blind decoding operation succeeds, determining resources other than resources overlapped with the resource region of the PDCCH candidate in the resource region of the first PDSCH as first reception resources in which a reception operation of a downlink channel is performed, and performing the reception operation in the first reception resources; and
when the blind decoding operation fails, determining the resource region of the first PDSCH as second reception resources in which the reception operation of the downlink channel is performed, and performing the reception operation in the second reception resources,
wherein when the number of overlapping resource elements between the resource region of the first PDSCH and the resource region of the PDCCH candidate is not below the threshold, the blind decoding operation is not performed.
