Abstract:
1. A method of combining a channel quality estimate for a radio channel based on a direct measurement of carrier and interferer energies, and a channel quality estimate for the radio channel based on channel decoder metrics, to obtain a better overall estimate of the carrier-to-interference (C/I) ratio measure of the channel quality for the radio channel, said method comprising: obtaining a direct channel quality estimate based on carrier and interferer energies; obtaining a channel decoder metric based channel quality estimate; computing a confidence level, P(direct), for the direct channel quality estimate, and a confidence level, P(metric), for the decoder metric channel quality estimate wherein, multiplying P(direct) by the direct channel quality estimate and P(metric) by the decoder metric channel quality estimate; and adding the respective products to obtain a final channel quality estimate in terms of the carrier-to-interference (C/I) ratio for the radio channel.
