Method of terminal, terminal, method of base station, and base station in wireless communication system are provided. Method of terminal in wireless communication system includes receiving, from base station, rate matching information for a physical downlink shared channel (PDSCH) by a radio resource control (RRC) signaling, wherein the rate matching information includes time resource information and frequency resource information; and monitoring a physical downlink control channel (PDCCH) candidate except for a PDCCH candidate overlapped with a resource indicated by the time resource information and the frequency resource information, wherein a search space is defined by a set of PDCCH candidate for an aggregation level, a PDCCH candidate is defined by a set of control channel element (CCE) corresponding to the aggregation level, a CCE is defined by 6 resource element groups (REGs), and a REG is defined by one resource block (RB) daring one orthogonal frequency division multiplexing (OFDM) symbol.
