Abstract:
New wireless networks can perform enhanced beamforming training for a multiple access technique, such as orthogonal frequency division multiple-access (OFDMA). The configurations of the stations and the networks presented herein provide a multiple-station beam refinement protocol (MSBRP) that may be used to train the transmit end and/or the receive end for the stations in a dense wireless local area network (WLAN). The MSBRP can have at least two phases. The first phase concurrently trains the receive side of multiple responder stations from one set of training signals sent from an initiator station. Then, each responder station can send training signals to the initiator station in a set of ordered phases associated with each responder station. The MSBRP eliminates inefficiencies associated with conducting multiple BRPs that include only pairs of stations.
Abstract:
An exemplary aspect is directed toward methods, apparatus, and systems related to spatial reuse with overlapping basic service set. A device may determine an overlapping basic service set (OBSS) associated with one or more access points. The device may then reduce a transmit power by a first margin. The device may then increase a packet detection threshold associated with the OBSS by a second margin. The device then sends an uplink data frame to at least one of the one or more access points.
Abstract:
A Trigger may be carried in a DL MU PPDU to solicit an UL BA. Then, the AP sends out the following transmission in SIFS time based on the UL BA information. There are numerous situations however where the AP should process the information transmitted (in UL) by multiple STAs and respond to them within the SIFS time. Some AP implementations (in particular the ones that do not use massive hardware (VLSI) accelerators) may not be able to finish the process within the SIFS time due to a very long PHY (Physical Layer) transmission decoding time (e.g., 802.11ax is 16 uS symbols vs 4 uS in legacy IEEE 802.11) and long PHY and MAC information possessing.
