1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving configuration information on a first search space (SS) set and a second SS set, wherein the first SS set with a first index includes a first physical downlink control channel (PDCCH) candidate having a control channel element (CCE) aggregation level (AL) 8 and a third PDCCH candidate having a CCE AL 16, and wherein the second SS set with a second index includes a second PDCCH candidate having a CCE AL 8 and a fourth PDCCH candidate having a CCE AL 16;
receiving a PDCCH based on the configuration information;
determining a physical uplink control channel (PUCCH) resource based on an index of a first CCE for the PDCCH, wherein the index of the first CCE is determined based on a PDCCH candidate having a CCE AL 16 associated with the second SS set with the second index, in case that the first index of the first SS set is larger than the second index of the second SS set; and
transmitting a PUCCH based on the determined PUCCH resource.
