    Abstract: 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.

    Abstract: Certain aspects of the present disclosure relate to a low-overhead method for communicating Channel State Information (CSI) feedback in Very High Throughput (VHT) wireless communications systems. The present disclosure also provides packet formats for Null Data Packet Announcement (NDPA), CSI Poll and CSI feedback. In some cases, the CSI feedback may be too large to be carried in a single Media Access Control (MAC) protocol data unit (MPDU) or a Physical Layer (PHY) protocol data unit (PPDU), and a proposed protocol for CSI feedback segmentation can be then utilized.

    Abstract: An apparatus for wireless communication includes data generation logic configured to generate data to be transmitted to an access point and to determine that a size of the data exceeds a size of a first transmit opportunity (TX_OP). The apparatus includes data fragmentation logic configured to generate at least a first data fragment and a second data fragment based on the data, where a size of the first data fragment is selected based on the size of the first TX_OP. The apparatus further includes a wireless interface configured to transmit, during the first TX_OP, a first data packet to the access point, the first data packet including the first data fragments.

    Abstract: In a WLAN according to IEEE 802.11, a large amount of channel time can be consumed by beacons and probe responses. This can be particularly true in dense networks. Several solutions are provided: 1. The channel time can be reduced by transmitting frames such as probe responses at a high rate. 2. The rate at which the probe responses are sent can be selected via a rate function described herein. 3. The channel time can be reduced by omitting neighbor information in frames such as beacons and probe responses unless requested by a station. 4. (Claimed invention) Channel time can be reduced by omitting at least some data shared between probe requests and association requests. The method of wireless communication includes receiving, at an access point, a probe request, decoding the probe request to determine shared wireless device state information, storing the shared wireless device state information for at least a timeout period, transmitting a probe response indicating the timeout period; and receiving an association request omitting the wireless device state information within the timeout period. 5. The channel time may be reduced by omitting at least some data shared between probe responses and association responses.
