Patent ID: 7272359

Claim:
A method for communicating a signal, comprising: establishing one or more quality indicators at a first communication device, the first communication device comprising a plurality of antenna elements, the one or more quality indicators indicating a quality of one or more communication links between the first communication device and one or more second communication devices; determining a modification according to the one or more quality indicators, the modification describing, at least one adjustment of one or more modulation features of a plurality of modulation features for a frequency subband; modulating at least a subset of a plurality of signals in accordance with the modification, a signal of the plurality of signals associated with an antenna element of the plurality antenna elements, a signal of the plurality of signals having the frequency subband; and sending the plurality of signals from the plurality of antenna elements to yield a transmitted signal, wherein establishing the one or more quality indicators at the first communication device further comprises receiving one or more quality indication signals comprising a plurality of power control groups corresponding to the one or more quality indicators, and wherein determining the modification according to the one or more quality indicators further comprises: adjusting a first set of modulation features of the plurality of modulation features while maintaining a second set of modulation features of the plurality of modulation features, if a first bit value for a power-control bit at a first time period corresponds to a second bit value for a power-control bit at a second time period; and adjusting the second set while maintaining the first set, if the first bit value differs from the second bit value.
