Abstract: Aspects of the present disclosure provide techniques for interleaving in single user (SU) preamble puncturing in wireless local area networks (WLANs). In one implementation, an access point (AP) can identify an SU preamble puncture transmission, encode information for the SU preamble puncture transmission to produce encoded bits, parse the encoded bits into multiple segments, parse the encoded bits among multiple resource units (RUs) within each of the multiple segments, and perform a tone interleaving of the encoded bits within each of the multiple RUs.

Abstract: This disclosure provides systems, methods and apparatuses for detecting a presence of long training fields (LTFs) in packet extensions of high-efficiency (HE) packets. An apparatus requests a length of packet extensions to be used for a ranging operation. The apparatus receives an HE packet including a packet extension containing a selected number of LTFs based at least in part on the requested packet extension length. The apparatus performs the ranging operation based on a determination that the packet extension contains LTFs. In some aspects, the apparatus detects a presence of LTFs in the packet extension based on a bit provided in the HE packet. In some other aspects, the apparatus detects a presence of LTFs in the packet extension by extracting sequences from the packet extension.

Abstract: Methods, systems, and devices are described for supporting simultaneous (e.g., overlapping) data communications by a wireless communication device. More specifically, the described features generally relate to supporting SBS communications by providing mechanisms to help mitigate interference and/or coordinate medium access. One mechanism involves aligning the data communications to mitigate interference. Another mechanism involves using channel reservation signal (e.g., a clear-to-send-to-self (CTS2S) signal) to help maintain simultaneous medium access. Yet another mechanism involves setting a second backoff period for a second channel based at least in part on a first backoff period for a first channel in wireless devices.
Abstract translation: 描述了用于支持无线通信设备的同时（例如，重叠）数据通信的方法，系统和设备。 更具体地说，所描述的特征通常涉及通过提供帮助减轻干扰和/或协调媒体访问的机制来支持SBS通信。 一种机制涉及对齐数据通信以减轻干扰。 另一种机制涉及使用信道保留信号（例如，清除发送自己（CTS2S）信号）来帮助保持同时的媒体访问。 又一种机制涉及至少部分地基于无线设备中的第一信道的第一回退周期来设置第二信道的第二回退周期。

Abstract: A method and apparatus for concurrent wireless communications on multiple channels of the same frequency band. A wireless device receives a first data signal via a first transceiver chain while concurrently initiating a transmission of a second data signal via a second transceiver chain of the wireless device. The wireless device suspends updates to one or more tracking loops of the first transceiver chain in response to initiating the transmission of the second data signal. The updates to the one or more tracking loops may be suspended prior to transmitting the second set of data from the second transceiver chain. The wireless device may subsequently resume updates to the one or more tracking loops of the first transceiver chain after completing the transmission of the second data signal.

Abstract: This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to short training field (STF) designs and signaling that support distributed transmissions. A transmitting device that transmits data on a distributed resource unit (dRU) may transmit an STF sequence over a spreading bandwidth of the dRU according to an existing STF tone plan. Each STA allocated a dRU for transmission in a trigger-based (TB) physical layer convergence protocol (PLCP) protocol data unit (PPDU) maps its STF sequence to one or more spatial streams and may apply one or more global cyclic shift delays (CSDs) to the STF sequence mapped to the one or more spatial streams, respectively. As such, different global CSDs may be assigned to different STAs so that each STA transmits its STF sequence with different amounts of delay.

Abstract: This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to pilot tone designs that support distributed transmission. A transmitting device may modulate a physical layer convergence protocol (PLCP) protocol data unit (PPDU) on a number (M) of tones representing a logical RU associated with the legacy tone plan and may further map the M tones to M noncontiguous subcarrier indices associated with a wireless channel. The transmitting device may transmit the PPDU, over the wireless channel, with a number (N) of pilot tones each having a respective location relative to the M tones as mapped to the M noncontiguous subcarrier indices. In some implementations, the relative locations of the N pilot tones may be different than relative locations of a number (K) of pilot tones associated with the logical RU.

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.
