摘要： Systems and methods for reducing the number of silencing frames transmitted in a coexistence network are described. In some embodiments, a method may include abstaining from transmitting silencing frames until detection of a predetermined event. Predetermined events include, for example, detection of a retransmitted packet, detection of a transmission or packet rate drop, and/or detection that an expected packet has been missed. In some cases, two or more predetermined events may be logically combined in any suitable manner or order, and may occur in series or in parallel with respect to each other. Once the predetermined event(s) have been detected, a silencing frame may then be transmitted. In some cases, subsequent silencing frames may be transmitted to facilitate return to a maximum attainable transmission rate. An investigation or observation period during which silencing frames are transmitted despite the absence of a predetermined event may enable the collection of network statistics.
摘要翻译：描述了用于减少在共存网络中传送的消音帧数量的系统和方法。在一些实施例中，一种方法可以包括放弃传送消音帧直到检测到预定事件。预定事件包括例如重发分组的检测，传输的检测或分组速率下降，和/或已经错过预期分组的检测。在一些情况下，可以以任何合适的方式或顺序逻辑地组合两个或更多个预定事件，并且可以相对于彼此串联或并行地发生。一旦已经检测到预定的事件，则可以发送消音框。在一些情况下，可以发送后续的消音帧以便于返回到可达到的最大传输速率。尽管不存在预定事件，但在其间发送静音帧的调查或观察期可以使得能够收集网络统计信息。

摘要： A network includes an access point using a first protocol and a station using both the first protocol and a second protocol. The station uses the first protocol before a first threshold and a second protocol after the first threshold. A first duration between the second threshold and the first threshold is at least of sufficient length for the station to receive one data packet from the access point and send an acknowledgment. The station transmits to the access point a current clear-to-send packet at a current time during a current exchange based on success or failure of a previous exchange during which a previous clear-to-send packet was transmitted to the access point at a previous time.

摘要： A system and method for arbitrating channel access in a wireless device including co-located network transceivers are disclosed herein. A wireless device includes a first wireless transceiver and a second wireless transceiver. The first transceiver is configured for operation with a first wireless network. The second transceiver is configured for operation with a second wireless network. The wireless device further includes logic that determines which of the first and second transceivers is enabled to transmit at a given time. The logic causes the first transceiver to transmit a notification signal indicating a time period during which the second transceiver of the wireless device will perform a first wireless transaction, and during which, based on receiving the notification signal, a different wireless device performs a second wireless transaction via the second wireless network without transmitting a notification signal.

摘要： A system and method for reducing power consumption of a wireless device operating as a soft access point. In one embodiment, a wireless device includes a soft access point controller that configures the wireless device to operate as a group owner in a peer-to-peer wireless local area network. The soft access point controller includes a beacon controller. The beacon controller is configured to transmit beacon frames at a first periodic interval. The beacon controller is also configured to extend a discovery interval of a wireless station by transmitting acknowledgement packets at a second periodic interval. The second periodic interval is shorter than the first periodic interval and shorter than a minimum discovery scan timeout of the wireless station.
