Abstract: Wireless communications systems and methods related to performing adaptive autonomous uplink (UL) communications are provided. A first wireless communication device receives, from a second wireless communication device, an autonomous uplink transmission configuration. The first wireless communication device determines a transmission parameter in response to a link adaptation parameter based on the autonomous uplink transmission configuration. The first wireless communication device transmits, to the second wireless communication device, an autonomous uplink communication signal based on the determined transmission parameter.

Abstract: The present disclosure provides techniques for configuring the utilization of request-to-send/clear-to-send (RTS/CTS) protocol procedures based on varying conditions at the STA. For example, an AP may identify one or more conditions, when satisfied, may trigger the STA to either enable or disable uplink (UL) transmissions associated with a RTS/CTS protocol procedure. In some aspects, an AP may determine a transmit opportunity (TXOP) threshold for an STA and may determine whether to broadcast a message having the TXOP threshold to multiple STAs including the STA or unicast the message to the STA. An STA may receive a message from an AP having a TXOP threshold and may replace, based on an indication in the received message, a current TXOP threshold in the STA with the TXOP threshold in the received message. The STA may transmit an UL RTS frame in response to a determination that a planned TXOP duration satisfies the TXOP threshold.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for improving transmission opportunity (TxOP) truncation in wireless communication. In some implementations, a transmit opportunity (TxOP) period truncation or whether to update a network allocation vector (NAV) timing based on a message that includes transmitter and receiver information (such as a transmitter address (TA) and a receiver address (RA)) may be determined. For example, a station may receive a contention-free end (CF-End) frame and determine a TxOP period truncation based on comparing a TA and an RA included in the CF-End frame with a TA and an RA included in an earlier received message (e.g., an RTS). Such information may be compared to other TAs or RAs associated with NAV timing values and the NAV timing may be set, reset, updated, or canceled based on the comparison.

Abstract: Systems and methods for controlling a delay associated with paging a remote device. In one implementation, a paging device arranges page operations such that if one of two consecutive page scans performed by a remote device occurs during a response scan, the other page scan occurs during the transmission of a page. In another implementation, a device scanning for a page arranges page scans such that if one of two consecutive page scans occurs during a page response scan, the other page scan occurs during the transmission of a page. In another implementation, a device scanning for a page performs a series of sets of separate page scans, wherein the time interval between two of separate scans in a set is less than the time interval between adjacent sets. The page scans in a set are configured to ensure that one of them occurs during the transmission of a page.

Abstract: Certain aspects of the present disclosure relate to including deferral information in postambles and midambles. An apparatus for wireless communications may generally include a processing system configured to generate a first frame having at least one of a midamble or a postamble that provides an indication of a request for a device to defer transmitting for a duration and an interface configured to output the first frame for transmission. Another apparatus for wireless communications may generally include a processing system configured to generate a frame having at least one of a midamble or a postamble designed to allow a device, after exiting a low-power state, to perform synchronization to the frame and an interface for outputting the frame for transmission. Including midambles and postambles in a frame allow for more reliable responses and may reduce throughput losses and interference.

Abstract: A network configurator can dynamically configure a device to couple network data between other devices in a wireless network. The devices can include two independent wireless transceivers that can each operate within different frequency bands, such as the 2.4 GHz and 5.0 GHz frequency bands. The configuration of the independent wireless transceivers can be based, at least in part, on device capabilities of the wireless transceivers, channel conditions, and a quality of service associated with the other wireless stations in the wireless network.

Abstract: Various aspects of the disclosed approach described herein allows a reduction of preamble overhead by tailoring transmitted packet preambles based on an expected level of clock-related offset between a transmitter and a receiver for a pair of communicating nodes. An estimate may be maintained at the transmitter of maximum time and frequency offsets between the transmitter and the receiver. The estimate may then be utilized to create a customized preamble sequence for generating the packet preamble. The estimate may also be utilized to select a particular modulation technique for the packet preamble.
