Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus obtain a signal from a remote wireless node. The apparatus may switch between a first mode and a second mode in response to the signal. The apparatus may sense the shared transmission medium and sense if an absence of traffic is detected. The apparatus may delay data transmission for a fixed time interval from detecting the absence of traffic. The apparatus may initiate the data transmission at the end of the fixed time interval if operating in the first mode or initiate the data transmission at the end of a random time interval following the fixed time interval if operation in the second mode.

Abstract: Methods, systems, and devices are described for wireless communication at a station. The station identifies a first set of enhanced distributed channel access (EDCA) parameters for a first access category based at least in part on a first traffic type and a determination that a multiple user (MU) frame is to be transmitted, and contends to gain access for a transmission opportunity over a shared radio frequency spectrum band to communicate with a plurality of other stations in a MU mode. The contention is based at least in part on the first set of EDCA parameters.

Abstract: Aspects of the present disclosure relate to receiving, at a first node and from a second node configured for full-duplex wireless communications, a signal indicating an interference floor for receiving signals at the second node, wherein the interference floor is based on interference caused by a transmitter of the second node, determining, by the first node and based at least in part on the interference floor, a modulation and coding scheme (MCS) for transmitting one or more signals to the second node, and transmitting, by the first node and based on the MCS, the one or more signals to the second node.

Abstract: Methods and apparatus for allocating multi-user communication resources to one or more stations for uplink data transmissions are provided. In one aspect, a method for allocating multi-user communication resources to one or more stations for uplink data transmissions is provided. The method comprises generating a request frame requesting an uplink buffer report from each of the one or more stations, the request frame selectively requesting that the uplink buffer report indicate either an amount of data in an uplink buffer or a requested amount of time to transmit the data in the uplink buffer. The method comprises transmitting the request frame to each of the one or more stations. The method comprises receiving the uplink buffer report in a report frame from each of the one or more stations.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify an aggregation capability to communicate in parallel over a plurality of wireless links. The wireless device may in some cases broadcast this aggregation capability (e.g., periodically). Additionally or alternatively, the wireless device may transmit the aggregation capability in response to a request received from another wireless device. In some cases, the first wireless device may transmit a request to a second wireless device inquiring about aggregation capabilities of the second wireless device. The second wireless device may respond with its aggregation capabilities (e.g., or may broadcast its aggregation capabilities independently of receiving the response). The wireless devices may establish a multi-link session based at least in part on the indicated aggregation capabilities.

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: A method of wirelessly communicating a packet includes generating, at a first wireless device, a first packet including a first preamble decodable by a plurality of devices and a second preamble decodable by only a subset of the plurality of devices. The first preamble includes a first signal field. The second preamble includes a first training field. The method further includes transmitting the first packet concurrently with one or more second packets to be transmitted by wireless devices other than the first wireless device.

Abstract: Devices and methods for synchronized group messaging in a wireless communication system are described. Multicast transmissions, such as those in a dense network, can cause significant medium usage because same multicast packet is likely sent by multiple APs at different time. Medium usage in such implementations may be redundant. As such, the transmission medium is not used optimally. Devices and methods which coordinate and align group messages (e.g., multicast packets) amongst APs are described. Each AP may be configured to transmit identical packets at the same time. Therefore, medium usage can be reduced, while the range can be extended due to accumulated energy from APs.

Abstract: Methods and systems for sounding a wireless network are disclosed. In one aspect, a method includes receiving, by an access point a message including a beamforming report from a device. The device may be a station that is outside a basic service set of the access point. The method also includes transmitting a message to the device based on the beamforming report. For example, in some aspects, the access point may utilize the beamforming report to perform a coordinated beamforming, multi-access point transmission or a multi-access point MIMO transmission. In some aspects, the access point may transmit an interference nulling signal to the device based on the beamforming report. The nulling signal compensates for another simultaneous transmission by the access point that interferes with the device's reception of a message from an access point with which the device is associated.
