    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: An apparatus for wireless communication includes data generation logic configured to generate (1002) data to be transmitted to an access point and to determine (1004) that a size of the data exceeds a size of a first transmit opportunity (TX OP). The apparatus includes data fragmentation logic configured to generate (1006) at least a first data fragment and a second data fragment based on the data, where a size of the first data fragment is selected based on the size of the first TX OP. The apparatus further includes a wireless interface configured to transmit (1008), during the first TX OP, a first data packet to the access point, the first data packet including the first data fragments.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an access point. The access point transmits, to one or more stations, a first message indicating resource allocation and a specific time for the one or more stations to transmit uplink data based on downlink transmission of a second message. The access point transmits, to the one or more stations, the second message in the downlink transmission. The access point receives the uplink data from the one or more stations at the specific time based on the downlink transmission of the second message in accordance with the resource allocation.

    Abstract: Methods and apparatus for multiple user uplink are provided. In one aspect, a method for wireless communication is provided. In an embodiment, a method includes transmitting a trigger frame to two or more stations, the trigger frame indicating an uplink transmission opportunity, the trigger frame message further comprising a request that the two or more stations concurrently transmit uplink data at a specific time, wherein the trigger frame comprises a duration field that indicates only a duration of a physical layer convergence protocol (PLCP) protocol data unit (PPDU) for a plurality of uplink data transmissions that the two or more stations are allowed to send. The method further includes receiving a plurality of uplink data from at least two stations at the specific time. Embodiments of the disclosure may provide an improved protocol for uplink transmissions from multiple terminals.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a configuration message that includes overlapping basic service set (OBSS) coordination parameters. The OBSS coordination parameters may be used to select an OBSS preamble detection (PD) threshold or a transmission (TX) power, or both. For example, an OBSS coordination parameter may include an indication of an OBSS PD threshold or the TX power or a range of OBSS PD thresholds or TX powers. In some cases, the coordination parameter may include selection criteria that may be used to select the indicated OBSS PD threshold or TX power. Additionally or alternatively, a range of selection criteria may be used to select from a range of OBSS PD thresholds and TX powers. The wireless device may use the selected OBSS PD threshold or TX power to communicate with an AP or other devices.
