摘要： There lies a challenge to develop a technique of effectively establishing a direct communication link between client devices in a communication network. In some implementations, an associated STA is a client device which is associated with a particular access point (AP). A non-associated STA is a client device which is not associated with the AP. A tunneled probe request may be transmitted by an associated STA through the AP to be broadcast to other associated STAs. In some implementations, an active scan may be combined with a tunneled probe request in order to establish a communication link between an associated STA and a non-associated STA.

摘要： A power conservation method and system are provided for conserving power in client terminals by using a partitioned proxy server. The client terminal, having low-power and high-power communication interfaces, may power down its high-power communication interface to conserve power. Prior to shutting off its high-power communication interface, the client terminal may assign a partitioned proxy server to act as its proxy. The partitioned proxy server may include remote and local paging proxies which communicate with each other over an IP network. The remote paging proxy receives paging requests from an access point or the communication network and forwards it to the local paging proxy. The local paging proxy then forwards the paging message to the client terminal via a low-power communication interface. Upon receipt of the paging message via its low-power communication interface, the client terminal may power up its high-power communication interface and directly respond to the paging message.

摘要： Systems and methods for reducing overhead in a communication system are disclosed. Different frame types are aggregated into an enhanced aggregated frame in response to a determination that the different frames are suitable for transmission within a single reservation period. In an embodiment, at least two frames of different types are identified, the suitability of an aggregated frame comprising at least a portion of each of the at least two frames for transmission during a first time duration is determined, and if suitable the aggregated frame is formatted for transmission by a transceiver. If unsuitable for transmission in the first time duration, a second time duration longer than the first time duration in which the aggregated frame is suitable for transmission is defined, and the aggregated frame is formatted for transmission by the transceiver.

摘要： Wireless video transmissions over a MAC layer employ various techniques to improve throughput which may negatively impact latency, such as Block-ACK and data aggregation. To improve latency while continuing to improve throughput, data packets are fenced according to application layer specifications and then transmitted. For video data, Block-ACK sequences and aggregation sequences are terminated at the end of video frames or video slices. For data aggregation, a physical layer data packet concludes at the end of a video frame or slice. The application layer can indicate to the MAC layer when such packet fencing is to occur. In use with 802.11n transmission a data flag may be used by the MAC layer to facilitate fencing.
