Abstract: A method and a system is disclosed for providing quality of service (QoS)-driven channel access within a basic service set (BSS) in a wireless local area network (WLAN). A contention control (CC) frame is sent from a point coordinator (PC) of the BSS during a contention-free period (CFP) of a superframe that includes the contention-free period (CFP) and a contention period (CP). The CC frame contains information relating to at least one of a priority limit for a next centralized contention interval (CCI), a length of the next CCI, a permission probability associated with the next CCI and information relating to a reservation request (RR) frame successfully received by the PC in a previous CCI. A non-colliding RR frame is then received at the PC in the CCI following the CC frame. The received RR frame is sent from a non-PC station in the BSS when at least one centralized contention opportunity (CCO) is available during the CCI after the CC frame. The RR frame indicates that the non-PC station sending the RR frame has at least one buffered data frame for transmission.

Abstract: Each of a plurality of nodes in a wireless network is capable of generating, transmitting, and receiving beacons in a distribute fashion. Each beacon contains information regarding the order of which other nodes are to transmit beacons and wireless medium access information at to when various nodes are to access the network. Nodes that are in separate “extended neighborhoods” are permitted to transmit their beacons simultaneously without risking beacon collisions. The beacons contain information that is used to ensure this result. Using the distributed beacon mechanism, each nod can reserve access to the wireless medium. In the disclosed embodiments, a central coordinator is not needed.

Abstract translation: 无线网络中的多个节点中的每一个能够以分布的方式生成，发送和接收信标。 每个信标包含关于其他节点要传送信标的顺序的信息和当各种节点要访问网络时的无线介质访问信息。 在不同的“扩展邻域”中的节点被允许同时发送它们的信标而不会发生信标冲突的风险。 信标包含用于确保此结果的信息。 使用分布式信标机制，每个节点可以预留对无线介质的访问。 在所公开的实施例中，不需要中央协调器。

Abstract: A virtual stream (VS) in a basic service set (BSS) in a wireless local area network (WLAN) that exists solely within the medium access control (MAC) sublayer of the WLAN. The VS includes a unidirectional path in the wireless network between a station sourcing a quality of service (QoS) session and at least one station receiving the QoS session in the same BSS. The VS is defined by a VS identifier (VSID) that is unique within and local to the BSS, an address of the sourcing station, and an address of the at least one receiving station. The VS can be a virtual down-stream (VDS), a virtual upstream (VUS) or a virtual side-stream (VSS). The VS can be a unitcast or a multicast VS.

Abstract: A method and an apparatus provide for controlled access to a shared communication medium. Time slots on a forward channel include information regarding status useful for remote units to determine whether a reverse channel is available for seizure. Additionally, information along the forward channel provides guidance to the remote units to control attempts to seize the reverse channel. In one embodiment a remote unit divides a data package into a plurality of portions and attempts to seize the reverse channel using a single portion of the data package which corresponds to one time slot on the reverse channel. It then waits until it receives notification along the forward channel that the first data portion was successfully received before it attempts to send any of the remainder of its data in consecutive time slots on the reverse channel.

Abstract: A method of synchronizing timers in a wireless network is described. According to some embodiments, a master timer is sampled at the start time of a first beacon in a first data object and the sampled master timer value is broadcast in a second beacon of a second data object. A slave timer is sampled at the start of the second beacon in the second data object and a value representing the duration of the first data object is subtracted from the sampled slave timer value to determine an updated sampled slave timer value. According to some variations, a difference is determined between the sampled master timer value and the updated sampled slave timer value. The method then uses the difference to synchronize the slave timer to the master timer and to other slaver timers synchronized to the same master timer.
