    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 method of transmitting a data frame is disclosed and may include transmitting a preamble, transmitting a physical layer convergence protocol (PLCP) header, and transmitting a plurality of MAC protocol data units (MPDUs). Each MPDU may be configured to reset a convolutional decoder state after each MPDU. The method may also include transmitting an MPDU aggregation header. The MPDU aggregation header may include a count of packed MPDUs, an array of offsets, an array of lengths, a frame check sequence (FCS) for the MPDU aggregation header, a group of tail bits, or a combination thereof. Further, an end of the MPDU aggregation header may be aligned to an interleaved symbol boundary.

    摘要: Techniques for dynamic task distribution and processing in a wireless communication system are described. In one embodiment, the wireless communication system includes a sensor configured to measure a characteristic and to transmit information indicative of the measured characteristic. The system includes a mobile device configured to receive and aggregate the information transmitted by the sensor, perform one or more tasks related to the aggregated information, determine whether a condition necessary for transferring a subset of the tasks is satisfied, and transfer the subset of the tasks for further performance. The system further includes a local gateway device configured to receive and aggregate the information indicative of the measured characteristic from the sensor and perform tasks related to the aggregated information, receive and perform the transferred subset of the tasks from the mobile device, and transfer the tasks for further performance.

    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: 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.

    摘要: A method of peer discovery in a communications network includes transmitting, by a first client station, a request to a second client station; receiving a response of the second client station, at least one of the request and the response including a local IP address of the corresponding client station; and establishing a tunneled direct link setup (TDLS)direct link between the first client station and the second client station based on the local IP address.
