Apparatus and method for assessing decode reliability of radio transmissions

摘要

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.

主权项

1. A method for wireless communication, the method comprising:
receiving one or more radio frames or parts of a frame of a voice call on a downlink channel; demodulating the received one or more frames or parts of the frame; decoding the demodulated one or more frames or parts of the frame; computing one or more demodulator-based metrics; computing one or more decoder-based metrics; combining 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, parameters of the reliability function being adaptively adjusted during the voice call to tune the reliability function over time, the parameters of the reliability function being different from the one or more demodulator-based metrics and the one or more decoder-based metrics; and accepting or rejecting the decoded one or more frames or parts of the frame based on the assessment of the reliability of said frames or parts of the frame.
