Claim of US Patent No. 10,219,274

1. A method comprising:sensing a group of channels for a channel contention operation that acquires two or more channels of the group of channels and detects a busy channel of the group of channels;
based on the channel contention operation, determining a channel bonding indicator that signals which ones of the group of channels are component channels;
generating a preamble portion of a frame that includes the channel bonding indicator, wherein generating the preamble portion comprises duplicating a legacy preamble on each of the acquired channels within the preamble portion;
generating a data portion of the frame, wherein generating the data portion comprises (i) setting first subcarriers that correspond to the acquired channels to data values, and (ii) setting second subcarriers that correspond to the busy channel to null values for at least a portion of the data portion of the frame; and
transmitting the frame to one or more devices.
