Title:
無線通信システムにおける電力制御設定点を調整する方法およびシステム
Document Type and Number:
Japanese Patent JP4142448
Kind Code:
B2
Abstract:
Techniques to adjust the setpoint of a power control loop in a wireless communication system. The setpoint may be adjusted based on frame status indicative of erased/good decoded frames, one or more (typically soft) metrics indicative of the confidence in the decoded results, power surplus/deficit indicative of the difference between the received signal quality and the setpoint and a threshold Eb/Nt needed for the desired level of performance, or a combination thereof. The metrics include one of a re-encoded power metric and a modified Yamamoto metric. The setpoint may be adjusted in different manners and/or by different amounts depending on the above-noted factors. The techniques may be employed for forward and/or reverse links in CDMA systems.
