  • Patent number: 8412259
    Abstract: Outer-loop power control methods and apparatus are disclosed. In an exemplary embodiment, a short-term block error rate is measured for a received signal, and a coarse adjustment to a target signal-to-interference ratio (SIR) is calculated as a function of the short-term block error rate, a target block error rate, and a first loop tuning parameter. In some embodiments, a fine adjustment to the target SIR is also calculated, as a function of a smoothed block error rate, the target block error rate, and a second loop tuning parameter. The coarse adjustment provides quick responsiveness to received block errors, while the fine adjustment moderates the coarse adjustments by accounting for a longer-term view of the received block error rate. The target SIR adjustments disclosed herein may be computed in each of several iterations of an outer-loop power control loop.
