Abstract
Disclosed herein is a method of detecting a physical downlink control channel (PDCCH) in a long-term evolution (LTE) system. In this method, one is selected from among possible PDCCH formats for received base station signals, and a signal corresponding to the length of the selected PDCCH format is retrieved. Thereafter, one is selected from among one or more of possible DCI formats that have not been selected yet. Thereafter, decoding is performed using the retrieved signal and the selected DCI format. Finally, a remainder is obtained by dividing the decoded signal by a cyclic redundancy check (CRC) pattern, and the remainder is stored as RNTI information, along with the selected DCI and the DCI format.
