摘要： Embodiments addressing MAC processing for efficient use of high throughput systems are disclosed. Data associated with at least one MAC ID can be aggregated into a single byte stream. The single byte stream can be formatted into MAC PDUs and then muxed. The muxed MAC PDUs can then be transmitted on a single MAC frame. Muxing of the MAC PDUs can be based on the priority of the MAC PDUs or other criteria. A MAC header can comprise information about the muxed PDUs, such as a pointer, that identifies the location of the MAC PDUs within the MAC frame. A MAC frame can contain partial MAC PDUs. The transmitted muxed MAC PDUs can be retransmitted, and an acknowledgment or feedback scheme may be used to help manage the transmission of the protocol data units.

摘要： Embodiments for bandwidth allocation methods, detecting interference with other systems, and/or redeploying in alternate bandwidth are described. Higher bandwidth channels may be deployed at channel boundaries (410), which are a subset of those for lower bandwidth channels (310), and may be restricted from overlapping. Interference may be detected (930) on primary, secondary, or a combination of channels, and may be detected in response to energy measurements (910) of the various channels. When interference is detected, a higher bandwidth Basic Service Set (BSS)(100) may be relocated to an alternate channel, or may have its bandwidth reduced to avoid interference. Interference may be detected based on energy measured on the primary or secondary channel, and/or a difference between the two. An FFT (1010) may be used in energy measurement in either or both of the primary and secondary channels. Stations may also monitor messages from alternate systems to make channel allocation decisions. Various other aspects are also presented.

摘要： Mesh Network Access Points (APs) points, including gateways and routers, are deployed over a geographic area. The APs monitor the communication channel for other carriers and transmit accordingly. The APs selectively co-transmit when other carriers are sensed, if the efficiency of the mesh network will improve. APs select a transmission rate based on observed carrier-to-interference ratios. APs use directional antennas to increase carrier-to-interference ratios and spectral efficiency. AP transmit schedules are adaptable and adjusted according to observed carrier-to-interference measurements.
