Method for adjusting the configuration of a reverse channel quality indicator channel (R-CQICH) based on quality metrics determined in a base station of a cellular communication network

摘要

In a 3G cellular network, a Reverse Link Channel Quality Indicator Channel (R-CQICH) may be transmitted on a reverse link (24) to support forward link high-speed data transmissions. Accordingly, the R-CQICH may be utilized to track the quality of the signal path (20) between the wireless unit (18) and the base station (12). The base station (12) may include a CQI component that utilizes a received Channel Quality Indicator (CQI) signal from the wireless unit (18) to generate CQI quality metrics based on the quality of the received signal. Also, the CQI quality metrics may be compared to different thresholds (149) to adjust various system configurations (151) said system configuration (151) may include settings for the R-CQICH. The base station (12) may also provide feedback to the wireless unit (18) with the updated system configurations (151). This technique allows CQI quality metrics to be utilized to adjust system configurations (151) dynamically and enhance the operation of a wireless system (10).
