An operating method of a terminal, the operating method includes determining a decoding priority of a plurality of aggregation levels based on reference information, the plurality of aggregation levels corresponding to a downlink control channel, performing candidate filtering-based blind decoding on one or more control channel candidates corresponding to the plurality of aggregation levels according to the decoding priority to obtain a decoding result, and receiving downlink control information based on the decoding result.

UE performing blind decoding, communication system including the same, and operation method of the UE and the communication system

Systems and methods are described for a method of operating a wireless communication device includes receiving a physical downlink control channel (PDCCH) including a plurality of control channel elements (CCE), storing a plurality of LLRs generated by demodulating the PDCCH in a data buffer, storing at least one address of the LLRs, corresponding to a plurality of PDCCH candidates in accordance with an aggregation level for the CCEs, in a plurality of address buffers, and performing blind decoding on the PDCCH candidates by using the data buffer and the address buffers.
