摘要： In order to better and more easily identify candidate APs and/or channels, an AP can transmit frames announcing its capabilities in a channel where it is not serving. For example, if an AP is operating in channel 1 and has created a Basic Service Set ID (BSSID) in that channel, it is permitted to transmit frames announcing its capabilities in another channel, for example channel 3, where another AP may or may not be operating.
摘要翻译：为了更好和更容易地识别候选AP和/或信道，AP可以在其不在服务的信道中传送宣布其能力的帧。例如，如果AP在信道1中操作并且在该信道中创建了基本业务集ID（BSSID），则允许在另一个信道（例如信道3）中传送其能力的帧，其中另一个AP可以或可以不运行

摘要： An apparatus and method is provided for measuring medium activity patterns in wireless networks and deriving information about the radio environment from the measured medium activity/patterns. This invention is three-fold. First, it defines what to measure, including medium idle/busy patterns based on power detection, medium idle/busy pattern based on preamble detection, and medium idle/busy pattern based on virtual sensing. Second, it provides a mechanism for communicating the measurement request and report, as illustration for the case of IEE 802.11. And last, it defines the information that can be derived given these measurements as discovery of: non-802 devices, 802.11e systems, 802.11e contention-based medium access priorities, 802.11e controlled medium access usage, 802.11b/g existence, and hidden stations.

摘要： A granted TxOP holder transmits the first frame of a QSTA-to-QSTA communication at a power level sufficient to ensure correct reception by the destination and at least detection by the HC, and then, with exceptions, transmits subsequent frames at a power level merely sufficient to ensure correct reception by the destination, regardless of reception or detection by the HC. Subsequent frames that must be received by the HC, such as those changing the TC queue size or requesting extension of the current TxOP, are transmitted at a power sufficient to ensure reception by the HC as well as the destination, as are the last frame(s). The HC is constrained from reclaiming the channel unconditionally merely because of failure to detect activity, and recovery is limited to the TxOP holder.

摘要： A wireless local area network (WLAN) includes at least one hybrid coordinator (HC) and at least one Quality of Service Station (QSTA). The HC transmits a schedule frame element (SEF). The WLAN also includes a clocking mechanism that sets a substantially absolute start time of a service interval. A method of synchronizing the HC and the QSTA includes transmitting a schedule element frame (SEF), and setting a substantially absolute start-time of a service interval, and a first transmitted frame element.
