Methods of reverse link power control

摘要

Methods of reverse link power control are provided. A first example method includes first adjusting OFDMA transmission power based on first feedback signals during an OFDMA transmission and second adjusting OFDMA transmission power based on second feedback signals during periods between OFDMA transmissions. A second example method includes sending first power adjustment indicators based on measured OFDMA SINRs when receiving OFDMA transmissions from a mobile station and sending second power adjustment indicators based on estimated OFDMA SINRs when not receiving OFDMA transmissions from the mobile station. A third example method includes receiving a plurality of interference indicating signals from different base stations and determining whether to adjust a maximum transmit power threshold based on the plurality of interference indicating signals, the maximum transmit power threshold indicating the maximum permitted transmission power level below which transmissions are constrained.

1. A method of determining a maximum permitted transmission power level, comprising:
receiving at a mobile station a plurality of interference indicating signals from different base stations; and determining whether to adjust a maximum transmit power threshold of the mobile station based on the plurality of interference indicating signals, the maximum transmit power threshold indicating the maximum permitted transmission power level below which transmissions by the mobile station are constrained; and adjusting the maximum transmit power threshold of the mobile station by a first value based on a probability that an interference indicating signal of the plurality of interference indicating signals is greater than the maximum power transmit threshold, the first value being based on a quantity of the different base stations.
