    Abstract: CERTAIN ASPECTS OF THE PRESENT DISCLOSURE PROVIDE TECHNIQUES AND APPARATUS FOR SIGNALING THE BANDWIDTH TO BE USED FOR WIRELESS COMMUNICATIONS USING AN RTS/CTS (REQUEST TO SEND/CLEAR TO SEND) FRAME EXCHANGE, PROVIDING FOR BANDWIDTHS OF AT LEAST 20 MHZ, 40 MHZ, 80 MHZ, 160 MHZ, OR HIGHER. THIS EXCHANGE OF BANDWIDTH INFORMATION MAY BE PERFORMED IMPLICITLY-BY DETERMINING THE CHANNELS IN WHICH THE RTS/CTS FRAMES ARE ACTUALLY SENT-OR EXPLICITLY. IN ADDITION TO THIS BANDWIDTH INFORMATION EXCHANGE, ASPECTS OF THE PRESENT DISCLOSURE MAY ALSO ALLOW FOR NETWORK ALLOCATION VECTOR (NAV) PROTECTION IN MULTIPLE CHANNELS. IN THIS MANNER, THE WIRELESS MEDIUM MAY BE RESERVED, AND THE TRANSMISSION MAY BE PROTECTED FROM HIDDEN NODES. (FIGURE 6)

    Abstract: Providing fairness-based metrics for managing inter-sector interference of a mobile AN is described herein. By way of example, accumulation of resource utilization messages (RUMs) at a sector of the mobile AN can be based at least in part on a performance metric of that sector as compared with one or more neighboring sectors. In at least one aspect, performance metrics of multiple sectors of the mobile AN can be aggregated and a RUM accumulation rate of each sector is determined based on the aggregated metric. Accumulation rates can further be updated periodically as sector and/or aggregated metrics of the mobile AN change. Accordingly, accumulation and utilization of RUMs is based on inter-sector fairness to optimize overall wireless communication quality of service for the mobile AN.

    Abstract: Flows admitted to a mesh node may be controlled through contention access parameters. The admitting node may determine a desired transmission opportunity duration, and a transmission opportunity frequency. Furthermore, the node may achieve the flow rate and delay bound requirements of the admitted flow based at least in part upon the desired transmission opportunity duration, and the transmission opportunity frequency. The data rate and the access frequency of the admitted node may be monitored at the physical access level. The flow rate requirement may be accomplished based at least in part upon an adjustment to the transmission opportunity duration. The delay bound requirement may be accomplished at least in part upon manipulation of the contention access parameters. The transmission opportunity duration and the access parameters may be determined by the upstream admitting nodes, which may reduce congestion near mesh portals, and accomplish increased data transfer.

    Abstract: Techniques for scheduling flows and links for transmission are described. Each link is an oriented source-destination pair and carries one or more flows. Each flow may be associated with throughput, delay, feedback (e.g., acknowledgments (ACKs)) and/or other requirements. A serving interval is determined for each flow based on the requirements for the flow. A serving interval is determined for each link based on the serving intervals for all of the flows sent on the link. Each link is scheduled for transmission at least once in each serving interval, if system resources are available, to ensure that the requirements for all flows sent on the link are met. The links are also scheduled in a manner to facilitate closed loop rate control. The links are further scheduled such that ACKs for one or more layers in a protocol stack are sent at sufficiently fast rates.
