Patent ID: 7324605

Claim:
A method of communicating over a high-throughput communication channel comprising: transmitting a channelization field as part of a current data unit, the channelization field indicating a frequency and space configuration of subsequent portions of the current data unit; and transmitting a high-throughput training field in accordance with the frequency and space configuration indicated in the channelization field, the high-throughput training field to be used by a receiving station to estimate a channel matrix of the high-throughput communication channel, wherein the channelization field indicates whether the high-throughput communication channel is a wideband channel, the wideband channel comprising a concurrent use of two or more valid operating channels, and wherein when the channelization field indicates that the high-throughput communication channel is a wideband channel, the channelization field indicates which of the two or more valid operating channels comprise the wideband channel.
