A decoding method and apparatus for an uplink control channel are provided. The method includes steps as follows: an analyzing and separation step, analyzing received uplink control channel data by using a spread spectrum sequence, separating frequency domain data multiplexed by user equipments (UE) on each symbol of the same resource block (RB), and obtaining frequency domain data of each UE; a frequency offset estimation and compensation step, performing frequency offset estimation and frequency offset compensation on the frequency domain data of each UE when cyclic shifts of all UEs in the same RB are staggered with each other in the same time slot; and a decoding processing step, performing subsequent decoding processing on the data after frequency offset compensation. Through adding frequency offset estimation and compensation, the decoding accuracy of discontinuous transmission (DTX) is greatly enhanced in the case of big frequency offset. |
