摘要： Techniques for resolving blinded-node problems are described herein. One aspect operates on the physical (PHY) layer only, which a second layer operates on the medium access control (MAC) layer. Both aspects involve having a node stop processing a data packet that is not destined for it so as to be able to reserve its resources to detect control and other packets. An apparatus for implementing the techniques are also disclosed.
摘要翻译：本文描述了用于解决盲节点问题的技术。一个方面仅在物理（PHY）层上操作，第二层在介质访问控制（MAC）层上操作。这两个方面涉及使节点停止处理不发往其的数据分组，以便能够保留其资源以检测控制和其他分组。还公开了一种用于实现该技术的装置。

摘要： A plurality of methods, computer program product, and apparatus that use a lower 32 bit field of a 64-bit 802.11 TSF timer, so as to encode the reference time instant without the ambiguity as to whether there the reference time is referring to a future time or a past time. According to an aspect of the present invention, the fact that the low order 32 bits of the TSF timer wraps over in about 71 minutes is exploited to remove any ambiguity in the reference times contained in the Schedule Element frame. One method employs an algorithm base on distance between two reference points to determine whether the timer has wrapped around a time period, and another method uses a delay interval or a timeout to determine whether or not the TSF timer is wrapped or unwrapped. Another method includes determining whether an absolute value of X-O is less than, or greater than or equal to maximum value M/2.
摘要翻译：使用64位802.11 TSF定时器的低32位字段的多种方法，计算机程序产品和装置，以便对参考时刻进行编码，而不存在关于参考时间是指未来的歧义时间或过去的时间。根据本发明的一个方面，利用了大约71分钟内TSF定时器的低阶32位包裹的事实来消除包含在时间表元素帧中的参考时间中的任何歧义。一种方法采用基于两个参考点之间的距离的算法来确定定时器是否已经缠绕了一段时间，另一种方法使用延迟间隔或超时来确定TSF定时器是否被包装或解包。另一方法包括确定X-O的绝对值是否小于或大于或等于最大值M / 2。

摘要： Techniques for controlling transmissions in wireless communication networks are described. In one aspect, transmission control for a mesh network may be achieved by ranking mesh points or stations in the mesh network. In one design, the rank of a first station in the mesh network may be determined. At least one station of lower rank than the first station in the mesh network may be identified. At least one transmission parameter for the at least one station of lower rank may be set by the first station. In another aspect, stations may be assigned different transmission parameter values to achieve the data requirements of each station. At least one transmission parameter value may be selected for each station based on the rank, QoS requirements, amount of traffic, and/or achievable data rate for that station and may be sent (e.g., via a probe response message) to the station.
