Abstract
A method for performing outer loop power control in wireless communications includes initializing a time interval clock to count down a predetermined time interval; receiving and decoding a channel quality indicator (CQI) message; computing a decision metric value for each symbol in the decoded CQI message; determining whether the CQI message is erroneous; counting a number of erroneous CQI messages; and signaling a wireless/transmit receive unit to adjust an uplink transmission power on a condition that the time interval clock has expired and the number of erroneous CQI messages exceeds a threshold.
Claims20
A method comprising:
- receiving control channel transmissions;
- counting a number of erroneously received control channel transmissions during the time interval;
- counting a number of hissed control channel transmissions during the time interval;
- and
- reporting the number of erroneously received control channel transmission and the number of missed control channel transmissions.
An apparatus comprising:
- a receiver configured to receive control channel transmissions;
- a counter configured to count, during a first time interval, a number of erroneously received control channel transmissions and a number of missed control channel transmissions;
- and
- a reporting device configured to report the number of erroneously received control channel transmissions and the number of missed control channel transmissions counted during the first time interval.
An apparatus comprising:
- a receiver configured to receive control channel transmissions;
- a first counter configured to count a number of erroneously received control channel transmissions during a first time interval;
- a second counter configured to count a number of missed control channel transmissions during the first time interval;
- and
- a reporting device configured to report count values of the first counter and the second counter for the first time interval.
