    Abstract: Methods and apparatus for using code-division multiple access (CDMA) to transmit information via orthogonal frequency-division multiplexing (OFDM) to convey information from user terminals to an access point (AP) in a wireless local area network (WLAN) are provided. By using CDMA to convey information, a propagation delay between an access point (AP) and a user terminal may be determined by the AP, and timing adjustment information based on the delay may be sent to the user terminal. In this manner, subsequent uplink (UL) transmissions from multiple user terminals may be received simultaneously by the AP, despite the multiple user terminals having potentially different propagation delays.

    Abstract translation: 提供了使用码分多址（CDMA）通过正交频分复用（OFDM）发送信息以将信息从用户终端传送到无线局域网（WLAN）中的接入点（AP）的方法和装置。 通过使用CDMA来传送信息，可以由AP确定接入点（AP）和用户终端之间的传播延迟，并且可以将基于延迟的定时调整信息发送到用户终端。 以这种方式，尽管多个用户终端具有潜在的不同传播延迟，但是可以由AP同时接收来自多个用户终端的后续上行链路（UL）传输。

    Abstract: This disclosure provides methods, devices and systems for interpreting reserved bits and values associated with different releases of a wireless communication protocol. In some implementations, a wireless communication device may determine whether to terminate or continue reception of a physical layer protocol convergence protocol (PLCP) protocol data unit (PPDU) if it detects a reserved bit in the physical layer preamble set to an unsupported value (such as a value different than what is defined by a version or release of the wireless communication protocol supported by the wireless communication device). In some other implementations, a wireless communication device may determine whether to terminate or continue reception of a PPDU if it detects a field in the physical layer preamble set to a reserved value (such as defined by a version or release of the wireless communication protocol supported by the wireless communication device).

    IPC: H04L27/26

    Abstract: This disclosure provides methods, devices and systems for wireless communication, and particularly, for generating or receiving a multi-generation physical layer protocol data unit (PPDU). The multi-generation PPDU may concurrently include a first generation-specific preamble based on a first generation of a wireless communication specification (such as that defined by the Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards) and a second generation-specific preamble based on a second generation of the wireless communication specification in a same transmission. The generation-specific preambles may be generated based on bandwidth portions of a wireless channel that each generation-specific preamble will occupy in the multi-generation PPDU. One or more of the generation-specific preambles may be modified based on an aggregate bandwidth of the multi-generation PPDU. This disclosure includes several options for modifying one or more generation-specific preambles or data fields to accommodate their use in a multi-generation PPDU.

    Abstract: This disclosure provides systems, methods, apparatus, and computer programs encoded on computer storage media, for relative timing drift correction for distributed multi-user transmissions. In one aspect, a first access point (AP) may receive a first signal from a second AP. The first signal may be associated with a channel sounding procedure to be performed substantially simultaneously by the second AP and the first AP. The first AP may then receive a second signal from the second AP, and prior to a substantially simultaneous transmission by the second AP and the first AP. The second signal may include timing information relative to the first signal. The first AP may determine a start time of the substantially simultaneous transmission at the first AP based on the timing information, and may initiate the substantially simultaneous transmission according to the determined start time.

    Abstract: Methods, systems, and devices for wireless communications are described for control signaling in next generation wireless local area network (WLAN) environments. A message transmitted by an access point may allocate resources to a plurality of stations. The access point may be configured to allocate up to 320 MHz of total bandwidth along with coarse punctures. The access point may also allocate up to eight space-time streams to each station in a multi-user multiple-input multiple output (MU-MIMO) transmission, and support simultaneous transmission to up to sixteen stations. To support 320 MHz bandwidth and up to sixteen stations, one or more signaling fields used in other environments may be repurposed to effectively signal the additional resources available in a next generation WLAN.

    IPC: H04W52/38

    Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for preventing or reducing cross-network interference associated with a coordinated transmission on a wireless channel. A first access point (AP) of a first basic service set (BSS) and a second AP of a second BSS can concurrently use the wireless channel using a coordinated transmission during a portion of a transmission opportunity (TXOP). The TXOP owner (such as the first AP) may allocate a resource assignment to the second AP such that the resource assignment is conditionally available for use by the second AP in a coordinated transmission. The condition may prevent the resource assignment from being used by the second BSS when its use would cause interference to the first BSS. The condition may be based on a transmit power for downlink communication or uplink communication in the second BSS.
