1. 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.

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.
