US Patent 11363657 WiFi network operation with channel aggregation

A first communication device generates a first data unit, for transmission in a first channel segment of a communication channel, to include a first medium access control (MAC) address utilized by the first communication device for operation in the first channel segment of the communication channel. The first communication device generates a second data unit, for transmission in a second channel segment of the communication channel, to include a second MAC address, different from the first MAC address, utilized by the first communication device for operation in the second channel segment of the communication channel. The first channel segment and the second channel segment are non-overlapping frequency segments of the communication channel. The first communication device transmits the first data unit and the second data unit in, respectively, the first channel segment and the second channel segment, to one or more second communication devices.
