Reliability detection of channel quality indicator (CQI) and application to outer loop power control
First Claim
Patent Images
1. A method for testing communications with a base station, the method comprising:
- causing the base station to count a number of erroneously received control channel transmissions during a time interval;
causing the base station to count a number of missed control channel transmissions during the time interval;
causing the base station to report the number of erroneously received control channel transmissions and the number of missed control channel transmissions; and
determing, by analysis of the reported number of erroneously received control channel transmissions and the reported number of missed control channel transmissions, if the communications with the base station are within a predefined performance range.

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.

9. A base station having communications tested, the base station comprising:
-
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; wherein the number of counted erroneously received control channel transmissions and the number of counted missed control channel transmissions provide an indication if the communications with the base station are within a predefined performance range. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A base station having communications tested, the base station comprising:
-
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; wherein the number of counted erroneously received control channel transmissions and the number of counted missed control channel transmissions provide an indication if the communications with the base station are within a predefined performance range. - View Dependent Claims (18, 19, 20)
