Patent ID: 8719890

Claim:
A method for a selecting a channel from a plurality of channels for assignment to a remote device in a variable modulation unicast system, the method comprising: transmitting a plurality of first signals to a plurality of remote devices over a plurality of channel-paths to the plurality of remote devices, wherein each first signal utilizes a first modulation scheme; receiving a plurality of feedback signals from the plurality of remote devices in response to transmitting the first signals, wherein each feedback signal includes identification information for a corresponding remote device of the plurality of remote devices and a first metric value representative of the transmission characteristics of the channel-path to the corresponding remote device; assigning a first assigned-channel having an assigned-channel carrier frequency from the plurality of channels to the corresponding remote device in response to the received first metric signal from the corresponding remote device, wherein assigning the first assigned-channel to the corresponding remote device further includes: determining the availability of a subplurality of channels from the plurality of channels in response to the statistical information, wherein the availability of the channel is determined in response to the first metric values and identification information related to the corresponding remote devices previously assigned to the subplurality of channels; determining a modular scheme compatible with each of the subplurality of channels and the corresponding remote device; and selecting a channel from the subplurality of channels; and transmitting a second signal to the corresponding remote device, wherein the second signal includes information identifying the first assigned-channel determined in response to the received first metric signal.
