WiFi operation with channel aggregation

A first communication device configured for operating in a communication network, the first communication device comprising a network interface device configured to:

• generate a first bandwidth indication of a first bandwidth of a first channel segment of an operating channel of the communication network;
• generate a second bandwidth indication of a second bandwidth of a second channel segment of the operating channel of the communication network, the second bandwidth indication being separate from the first bandwidth indication, wherein
• i) the first channel segment and the second channel segment form the operating channel of the communication network and
• ii) the first channel segment does not overlap in frequency with the second channel segment;
• generate one or more media access control protocol (MAC) data units to include the first bandwidth indication and the second bandwidth indication;
• and
• transmit the one or more MAC data units to one or more second communication devices to indicate the first bandwidth of the first channel segment and the second bandwidth of the second channel segment of the operating channel of the communication network, to the one or more second communication devices;
• wherein the network interface device is configured to,
• generate the one or more MAC data units at least by generating a single MAC data unit to include both the first bandwidth indication of the first bandwidth of the first channel segment and the second bandwidth indication of the second bandwidth of the second channel segment, and
• transmit the one or more MAC data units at least by one of,
• i) transmitting the single MAC data unit in the first channel segment without transmitting the MAC data unit in the second channel segment, or
• ii) transmitting the single data in the second channel segment without transmitting the MAC data unit in the first channel segment.

• wherein the network interface device includes,
• i) a first radio frequency (RF) radio configured for operation in the first channel segment and not in the second channel segment and
• ii) a second RF radio configured for operation in the second channel segment and not the first channel segment;
• wherein the network interface device is configured to,
• generate the one or more MAC data units to include the first bandwidth indication and the second bandwidth indication at least by generating
• i) a first MAC data unit to include the first bandwidth indication and
• ii) a second MAC data unit to include the second bandwidth indication,
• transmit, via the first RF radio in the first channel segment, the first MAC data unit that includes the first bandwidth indication of the first bandwidth of the first channel segment, and
• transmit, via the second RF radio in the second channel segment, the second MAC data unit that includes the second bandwidth indication of the second bandwidth of the second channel segment.
