  • Patent number: 9408094
    Abstract: Disclosed are an apparatus and method for assessing decode reliability of voice, data and control channel transmissions. In an aspect, the apparatus and method are configured to receive one or more radio frames or parts of a frame on a downlink channel; demodulate the received one or more frames or parts of the frame; decode the demodulated one or more frames or parts of the frame; compute one or more demodulator-based metrics and one or more decoder-based metrics; combine the one or more demodulator-based metrics and the one or more decoder-based metrics using a reliability function that assesses reliability of the decoded one or more frames or parts of the frame; and accept or reject the decoded one or more frames or parts of the frame based on the assessment of the reliability of the decoded frames or parts of the frame.

  • Patent number: 8923171
    Abstract: Disclosed are methods and apparatus for reducing UE's power consumption by controlling early decoding boundary. In one aspect, a UE is configured to receive a data or voice frame from a base station. The UE selects one or more quality metrics for determining decoding boundary of the received frame and computes the selected one or more quality metrics. The UE then determines a decoding boundary for the frame based on one or more computed quality metrics. The UE then decodes the received frames at the determined decoding boundary and determines whether the decoding of the frame was successful. If the early decoding of the frame was successful, the UE may terminate reception of the frame. If the early decoding of the frame was unsuccessful, the UE may adjust the decoding boundary and decodes the frame at the adjusted boundary.
