Abstract: Provided are a user equipment performing a blind decoding operation, and an operating method of the user equipment. An operating method of a user equipment includes receiving a physical downlink control channel (PDCCH) including a plurality of control channel elements (CCEs) corresponding to one control resource set (e.g. a CORESET), determining a division value corresponding to a number of CCEs to be included in at least a first group of N groups of CCEs based on PDCCH configuration-related information, dividing the plurality of CCEs into the N groups based on the division value, performing CCE to resource element (RE) demapping on the first group, and decoding the demapped first group.

Abstract: An electronic device and a method of operating the electronic device in a wireless communication system are provided. The method includes determining whether to perform a partial decoding or a normal decoding based on a channel quality; if partial decoding is performed, decoding partial data received by a transceiver from a second electronic device during a part one TTI; when the decoding of the partial data succeeds, performing at least one complementary decoding until a decoding success count reaches a decoding threshold; and when the decoding success count reaches the decoding threshold, outputting a decoding result for the at least one complementary decoding; and if normal decoding is performed, decoding all data of the one TTI and outputting a result. One of the at least one complementary decoding comprises decoding previous data, and additional data received by the transceiver during an additional part of the one TTI, after the previous data.

Abstract: A method of wireless communication is described. A user equipment performs data communication based on a polar code with a base station by obtaining a physical downlink control channel (PDCCH) candidate from at least one search area in a frequency band for the data communication, performing error detection on frozen bits of the PDCCH candidate, determining whether the PDCCH candidate is a valid PDCCH candidate based on a result of the error detection, and selectively performing polar decoding on the PDCCH candidate based on a determination result of the valid PDCCH candidate.
