摘要： A wireless communication network manages variable data rate communication channels using both short-term data rate adaptation and longer-term resource allocation adjustment. For example, an exemplary base station system may track the actual transmit power being used to transmit a given communication channel on a per frame basis, or faster, and use that tracked value to infer changing channel conditions, e.g., for a given current data rate, higher power indicates poorer channel conditions and lower power indicates better channel conditions. Additionally, or alternatively, channel quality information reported by a receiving mobile station can be used. Regardless, relatively fast data rate changes can be made responsive to monitoring the channel conditions, while retaining the communication resource allocation for the channel. Over the longer term, however, the allocation itself can be changed, e.g., increased or decreased, depending on whether the channel is being efficiently utilized.

摘要： A radio base station (RBS) provides dynamic rate adaptation for rate-adjustable communication channels used to transmit information to remote mobile stations based on monitoring transmit power information associated with those channels. For a given channel, the RBS tracks an average channel power on a per transmit frame basis and compares the average to first and second rate adjustment thresholds, which comparisons trigger downward or upward rate adjustments. Similar operation also may be based on averaging the power control commands returned by the mobile station, which indicate whether the channel's power as received by the mobile station is or is not sufficient with respect to a desired signal quality. This method thus provides a mechanism for rapid rate adaptation without requiring explicit rate control signaling from the mobile stations.
