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.
