    Abstract: Certain embodiments provide methods and apparatus for adjusting timing in an SDMA system. One method for adjusting the timing of packet transmissions in a wireless communications system, that may be performed by an access point, includes receiving ranging signals from a plurality of wireless network nodes, determining timing adjustment information for adjusting starting timing of packet transmissions from the wireless network nodes based on the ranging signals, and communicating the timing adjustment information to the wireless network nodes.

    IPC: H04L5/00

    Abstract: This disclosure provides methods, devices and systems for wireless communications over a 320 MHz bandwidth. Some implementations more specifically relate to signaling techniques for indicating the bandwidth of a physical layer convergence protocol (PLCP) protocol data unit (PPDU) transmitted in a secondary 160 MHz channel of the 320 MHz bandwidth. In some implementations, an access point (AP) may transmit an aggregated PPDU (A-PPDU) that includes a first sub-PPDU transmitted within a primary 160 MHz channel and a second sub-PPDU transmitted within a secondary 160 MHz channel. In such implementations, the first sub-PPDU may carry bandwidth information indicating the bandwidth of the first sub-PPDU within the primary 160 MHz channel and the second sub-PPDU may carry bandwidth information indicating the 320 MHz bandwidth.

    Abstract: This disclosure provides methods, devices and systems for generating enhanced trigger frames. Some implementations more specifically relate to trigger frame designs that support gains in data throughput achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an enhanced trigger frame may be used to solicit a non-legacy trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data unit (PPDU) from one or more wireless stations (STAs). In some implementations, the enhanced trigger frame may be configurable to support multiple versions of the IEEE 802.11 standard. For example, an enhanced trigger frame may be configured in accordance with a legacy trigger frame format or a non-legacy trigger frame format. Thus, when configured in accordance with the legacy trigger frame format, the enhanced trigger frame can also be used to a legacy TB PPDU from one or more STAs.

    Abstract: This disclosure provides methods, devices and systems for generating packet preambles. Some implementations more specifically relate to preamble designs that support gains in data throughput achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. Among other examples, the preamble designs of the present implementations may allow for more reliable packet detection, more accurate channel estimation, and more robust decoding of signal field (SIG) symbols. Additionally, or alternatively, the preamble designs of the present disclosure may be implemented with different lengths, modulation schemes, or transmit power compared to preamble designs that conform to existing versions of the IEEE 802.11 standard.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for group formation and sounding for distributed multi-user multiple input multiple output (MU-MIMO). Some implementations include a method of wireless communication. The method includes a sounding preparation phase that includes transmitting, to the plurality of access points, a first frame inviting the plurality of access points to perform a beamformed distributed transmission from the plurality of access points to a group of stations (805); receiving a second frame from at least one of the plurality of access points based on transmitting the first frame, the second frame including at least one identifier of at least one station in a different basic service set than a basic service set of the first access point (810); and identifying the group of stations based on the at least one identifier included in the second frame (815).
