1. A method for processing signals in user equipment (UE), comprising:
- receiving, by the UE, for each control channel of a plurality of control channels, a portion of an error detection-encoded message;
calculating, by the UE for each portion, a first quality metric based on an identity of the UE;
calculating, by the UE for each portion, a second quality metric based on the first quality metric; and
selecting, by the UE, one of the plurality of control channels based on the calculated first quality metric when the calculated second quality metric associated with the selected one of the plurality of control channels is higher than a specified threshold.

Abstract
Aspects of a method and system for processing control channel signals may include calculating at a receiver, for a portion of a sub-frame of each one of a plurality of control channels, first and second quality metrics. A control channel may be selected on the basis of the quality metrics. The calculating and selecting may be done for a first slot of a corresponding sub-frame. A validity of a selected control channel may be determined based on a CRC derived from decoding the selected control channel'"'"'s sub-frame.

1. A method for processing signals in user equipment (UE), comprising:
-
receiving, by the UE, for each control channel of a plurality of control channels, a portion of an error detection-encoded message; calculating, by the UE for each portion, a first quality metric based on an identity of the UE; calculating, by the UE for each portion, a second quality metric based on the first quality metric; and selecting, by the UE, one of the plurality of control channels based on the calculated first quality metric when the calculated second quality metric associated with the selected one of the plurality of control channels is higher than a specified threshold. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A receiver for processing signals in user equipment (UE), the receiver comprising:
-
a plurality of decoders configured to decode a corresponding plurality of control channels, each decoder from among the plurality decoders being configured to; receive a respective portion of an error detection-encoded message for a control channel of the plurality of control channels; calculate, for the respective portion, a first quality metric based on an identity of the UE; and calculate, for the respective portion, a second quality metric based on the first calculated quality metric; and a decision block, coupled to the plurality of decoders, configured to select one of the plurality of control channels based on the calculated first quality metric when the second calculated quality metric associated with the selected one of the plurality of control channels is higher than a specified threshold. - View Dependent Claims (9, 10, 11, 12, 13)

14. A receiver for processing signals in user equipment CUE), the receiver comprising:
-
a plurality of decoders configured to decode a corresponding control channel from among a plurality of control channels, each decoder from among the plurality of decoders being configured to; receive a respective portion of an error detection-encoded message for the corresponding control channel; and calculate, for the respective portion, a respective likelihood that the portion comprises desired data from among a plurality of likelihoods; and a decision block, coupled to the plurality of decoders, configured to select one of the plurality of control channels based on the plurality of likelihoods. - View Dependent Claims (15, 16, 17, 18)
