    摘要: A system and method for wireless devices to efficiently receive communications by transmitting and receiving specialized beacon messages. Particularly, a wireless device may await reception of a synchronizing beacon message from a transmitting device. A relative position identifier within the synchronizing beacon message may then allow the wireless device to anticipate future beacon message transmissions and to synchronize its reception pattern with the transmitter. In this manner the wireless device need only receive and decode beacon messages germane to its operation.

    摘要: A transmission parameter for a link in a wireless network is adapted for a current simultaneous transmission based on a loss parameter. The loss parameter is useable to determine an allocation for a wireless node of a plurality of wireless nodes participating in the simultaneous transmission. In some examples, the selected transmission parameter and loss parameters for a previous transmission, along with the loss parameter for the current simultaneous transmission are used to determine the transmission parameter. In some embodiments, an access point (AP) determines and communicates a loss parameter to a plurality of access terminals (AT). Each AT determines a modulation and coding scheme (MCS) based at least in part on the loss parameter. Each AT simultaneously transmits at least one data stream to the AP in accordance with the determined MCS. In some other embodiments, the transmission rate for simultaneous downlink communications is similarly adapted.

    摘要: Methods and apparatus for network setup in wide channel WLANs are provided. Techniques for co-existence of 20 MHz and 40 MHz networks (e.g., as defined by IEEE 802.11n) may be extended to 80 MHz and 160 MHz networks. For example, a primary channel of an existing network may be designated as the primary channel of a new network. Further, a primary channel of the existing network may not be used as a secondary channel in the new network. Intolerance operation between networks may include a first network releasing one or more channels in response to an intolerance indication received from a second network. Furthermore, in response to the intolerance indication from the second network, the first network may utilize one or more channels for communicating in the first network using a first set of access parameters. The access parameters may depend on the intolerance indication.

    摘要: One aspect of the disclosure provides a method for wireless communication by a station or wireless device. The method includes waking from a sleep state. Further, the method includes determining an availability of a transmission medium. In addition, in response to determining that the transmission medium is not available, the method can include determining a sleep time period, entering a second sleep state based on the sleep time period, and freezing a backoff counter for the duration of the second sleep state.
