Abstract:
1. A wireless communication system, comprising: means for determining a first channel bandwidth, a second channel bandwidth, a plurality of first channel boundaries, and a plurality of second channel boundaries, the second channel boundaries a subset of the first channel boundaries, the subset selected such that each of the plurality of second channel boundaries is separated from the remainder of the plurality of second channel boundaries by at least the second channel bandwidth; means for establishing a channel of the second channel bandwidth at one of the second channel boundaries; a first plurality of modulation formats available for use in a channel of the first channel bandwidth; a second plurality of modulation formats available for use in a channel of the second channel bandwidth, wherein at least one modulation format in the second plurality of modulation formats is different than each of the modulation formats in the first plurality of formats; means for establishing a first channel of the second channel bandwidth, wherein the channel comprises a primary channel and one or more secondary channels; means for communicating between two or more stations on the first channel using one or more of the second plurality of modulation formats; and means for detecting interference on the first channel.
