Realtime power control in OFDM systems

摘要

Systems and methods for efficiently transmitting power level information in a point to multipoint wireless system. Multiple subscriber units may transmit indications of their power level within a shared burst where one or more subchannels are allocated to each subscriber unit. The burst holding the power level information may be understood by the MAC layer to be a data burst. In this way, a wireline MAC protocol may be applied to wireless applications.
