Abstract: This disclosure provides methods, components, devices and systems for high-bandwidth communication on the 5 GHz band. Some aspects more specifically relate to greater than 160 MHz channel bandwidth communication between wireless communication devices. In one aspect, 240 MHz channel bandwidth communication from two contiguous channel bandwidths of 160 MHz with a punctured channel bandwidth of 80 MHz may be achieved. In some aspects, first devices operating on the 5 GHz band, such as stations (STAs) or access points (APs) may transmit an information element (IE) indicating an ability to operate at greater than 160 MHz and receive an acknowledgement from a second device, and the devices may begin communicating at greater than 160 MHz channel bandwidth. In some other aspects, the first IE may include additional information including channel segment information, puncture bitmap information, extremely high throughput (EHT) information, and modulation coding scheme (MCS) mapping information.

Abstract: A networking apparatus includes a communication circuitry configured to receive, via first control message data units (CMDUs), network information descriptive of links between network devices of a network. The networking apparatus also includes a processor configured to determine, based on the network information, an end-to-end routing path for unicast communications from the communication circuitry to a second network device of the network, where the end-to-end routing path traverses a first network device of the network. The processor is further configured to cause the communication circuitry to send, to the first network device via one or more second CMDUs, routing path information descriptive of at least a portion of the end-to-end routing path. The routing path information is configured to cause the first network device to forward, along the portion of the end-to-end routing path, unicast packets received from the communication circuitry and addressed to the second network device.
