Abstract
The error detection method includes decoding a portion of each control channel that is simultaneously received by a user equipment (UE) in a wireless communication system. The UE is provided with techniques to determine if one or more of the control channels were successfully received during the decoding step. If more than one control channel was successfully received, the method selects only one of the successfully received control channels based on calculated path metric differences (PMD) that serve as a “tie-breaking” mechanism to select the correct control channel for a particular UE.
