Abstract: An apparatus for wireless communication includes data defragmentation logic configured to receive, during a first transmit opportunity, a first data packet from a first device and a second data packet from a second device. The first data packet includes a first data fragment, and the second data packet includes a second data fragment. The apparatus also includes block acknowledgement generation logic configured to generate a block acknowledgement frame including a first block acknowledgement bitmap and a second block acknowledgement bitmap. The first block acknowledgement bitmap indicates at least the first data fragment received from the first device, and the second block acknowledgement bitmap indicates at least the second data fragment received from the second device. The apparatus further includes a wireless interface configured to transmit the block acknowledgement frame to the first device and to the second device.

Abstract: Methods, systems, and devices are described for wireless communication at a receiving device. A receiving device may receive a first physical layer header of a first wireless local area network (WLAN) protocol data unit over a shared radio frequency spectrum band. The first physical layer header may include at least a first basic service set (BSS) identifier and a first device association identifier (AID). The receiving device may perform, based at least in part on the first BSS identifier and the first device AID, an intra-frame operation including a power saving operation and/or a receive filtering operation.

Abstract: Systems, methods, and devices for transmitting data are described herein. In some aspects, a method comprises generating a first message. The first message may comprise an allocation of a first station to a first frequency channel and a second station to a second frequency channel. The method further comprises transmitting the first message over the first frequency channel and the second frequency channel. The method further comprises transmitting, after transmission of the first message, a second message to the first station using the first frequency channel. The method further comprises transmitting, after transmission of the first message, a third message to the second station using the second frequency channel.

Abstract: In some aspects, a method for configuring channel access parameters in a wireless communication system includes determining, at an access point, an enhanced distributed channel access (EDCA) parameter for a first subset of stations of a plurality of stations, the first subset of stations capable of transmitting multi-user uplink transmissions. The method further includes generating an information element including the EDCA parameter. The method further includes transmitting the information element such that the information element is decodable by the first subset of stations and not by a second subset of stations of the plurality of stations.

Abstract: Systems, methods, and devices for high-efficiency wireless frequency division multiplexing are provided. A method includes exchanging, at an access point, at least one frame reserving a wireless medium with at least one of a first and second wireless device. The method further includes receiving a first communication on a first set of wireless frequencies from the first wireless device. The method further includes receiving a second communication, at least partially concurrent with the first communication, on a second set of wireless frequencies from the second wireless device. The method further includes transmitting at least one acknowledgment of the first and second communication. The first set and the second set are mutually exclusive subsets of a set of wireless frequencies available for use by both the first and second wireless device.

Abstract: Methods and apparatus for multiple user uplink are provided. In one aspect, method for wireless communication includes receiving a message comprising a request for two or more stations to concurrently transmit an uplink transmission. The method further includes determining a status of a medium at a station based on a clear channel assessment (CCA) or a network allocation vector (NAV). The method further includes selectively transmitting the uplink transmission based on the indication of the status of the medium.

Abstract: Methods, devices, and computer program products for traffic information signaling in a wireless communications network are disclosed. In one aspect, a method of wireless communication network is disclosed. The method includes selecting, from a variable number of control fields, one or more control fields for inclusion in a frame. The method further includes generating the frame comprising the selected number of control fields, each control field comprising an end of control field, the end of control field storing an indicator indicative of an end of the selected number of control fields or a presence of another control field in the frame. The method further includes transmitting the frame.

Abstract: Techniques for reducing delay in scheduling traffic transmission in an overlapping basic service set (OBSS) environment by modifying backoff mechanisms are disclosed. In some examples, a device (e.g., station (STA), access point (AP)) decodes at least a portion of a preamble of a packet to determine whether the packet is sent by a member of an OBSS (e.g., STA, AP from a different BSS). Backoff operations are typically deferred as a result of the decoding. Aspects of the present disclosure provide a method, apparatus, and system in which the backoff operations are resumed prior to expiration of the period reserved for an OBSS packet by the network allocation vector (NAV). That is, the device may not honor the NAV of the OBSS packet, and instead perform spatial reuse by transmitting another packet (or signal) on the same frequency channel during the NAV of the OBSS packet.

Abstract: An acknowledgment (ACK) frame has two parts: a group ACK part and a scheduling information part. In the group ACK part, an ACK/NACK indicator is included for a previous uplink (UL) transmission per station (STA). In the scheduling information part, information included for the following UL transmission per selected STA may comprise, for example, one or more of: a number of selected STAs, a media access control (MAC) address of each selected STA, a data transmission duration per selected STA, a transmission rate per selected STA, a request transmission duration, a pilot transmission order, or a STA transmission order.
