Abstract:
Systems, methods, and devices for communicating packets having a plurality of types are described herein. In some aspects, the packets include a compressed MAC header. In some aspects the packets include an acknowledgment (ACK) frame. The fields included in a particular packet type may be based on the type of information to be communicated to the receiving device.
Abstract:
Certain aspects of the present disclosure relate to a technique for communicating Channel State Information (CSI) feedback. In some aspects, the CSI feedback is communicated in a very high throughput (VHT) wireless communications system.
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:
Systems, methods, and devices for communicating a compressed beacon are described herein. In some aspects, a method of communicating in a wireless network includes generating a compressed beacon. The compressed beacon includes a next full beacon time indication (NFBTI). The method further includes transmitting, at an access point, the compressed beacon.
Abstract:
Systems, methods, and devices for communicating a compressed beacon are described herein. In some aspects, a method of communicating in a wireless network includes creating a shortened network identifier having a first length from a full network identifier having a second length. The first length is shorter than the second length. The method further includes generating a compressed beacon including the shortened network identifier. The method further includes transmitting, at an access point, the compressed beacon.

Abstract:
Null data packet (NDP) frames for wireless communications are described herein. In one example, a method for wireless communication includes generating an NDP frame comprising a physical layer preamble having a legacy preamble portion and a nonlegacy portion. The method may also include transmitting the NDP frame.
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.
