Abstract: Methods, systems and apparatuses for enhanced coordinated channel access including access points (APs) and non-access points (non-APs). A first non-access point (non-AP) in a group of at least two non-APs can receive, from a second non-AP of the group of at least two non-APs, signaling including information corresponding to a transmission opportunity (TXOP). Additionally, the first non-AP can transmit, in accordance with the information corresponding to the TXOP and scheduling information of the group of at least two non-APs, first data to one or more devices, wherein the first data is transmitted to the one or more devices in at least a portion of the TXOP.

Abstract: A method performed by a wireless device operating in an uplink multi-user mode is described. The method includes determining that a condition exists to prompt the wireless device to transmit an unsolicited low latency presence frame to an access point to solicit transmission of a solicited control frame from the access point; transmitting the unsolicited low latency presence frame to the access point, the unsolicited low latency presence frame indicating a type of solicited control frame requested by the wireless device; receiving a solicited control frame from the access point, the solicited control frame comprising information relating to the unsolicited low latency presence frame; and performing an action based on the received solicited control frame.

Abstract: A method performed by a wireless device operating in an uplink multi-user mode includes: setting an exclusion bit in an operating mode control subfield of a transmit operating mode indicator frame, the exclusion bit indicating an exclusion of an AC or a TID from the uplink multi-user mode; sending, to the AP, a trigger-based physical layer protocol data unit (PPDU) comprising the transmit operating mode indicator frame; contending for channel access using an enhanced distributed channel access (EDCA) function to send the low latency data via an uplink; and transmitting the low latency data to the AP in a single user PPDU in accordance with EDCA-based channel contention.

Abstract: This disclosure relates to methods for transmitting and receiving multi-user request-to-send and clear-to-send frames in a wireless communication system. An access point wireless device may establish wireless connections with multiple wireless devices. The access point wireless device may transmit a multi-user request-to-send frame to the wireless devices. The multi-user request-to-send frame may indicate a transmit opportunity duration and allocate frequency resource units on which to transmit clear-to-send frames to the wireless devices. The wireless devices may transmit the clear-to-send frames on the allocated frequency resource units. The clear-to-send frames can include an indication of partial or full availability for the transmit opportunity.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including detecting a reception opportunity of a physical layer protocol data unit (PPDU) scheduled to be transmitted by a transmitter, where the PPDU includes a preamble and one or more media access control (MAC) PDUs (MPDUs); decoding the preamble of the PPDU; detecting that reception of the one or more MPDUs has failed; and in response to the detecting, preparing a Negative Acknowledgment (NACK) message for transmission to the transmitter.

Abstract: Methods, systems and apparatuses for managing coexistence interference by an access point (AP) and wireless device are described. The wireless device may perform communication with the AP and with another device. The wireless device may indicate characteristics of its communication patterns with the other device to the AP. The AP may determine times to communicate and/or avoid communication with the wireless device based on the characteristics.

Abstract: An interface circuit in a device, e.g., an access point, may perform link adaptation. During operation, the interface circuit may provide a wake-up frame, e.g., a LP-WUR packet, associated with a channel in a band of frequencies, where the wake-up frame is intended for a wake-up radio in a recipient device. Then, the interface circuit may receive, from the recipient device, feedback information associated with a second channel in a second band of frequencies, where the feedback information is associated with a main radio in the recipient device. Based at least in part on the feedback information, the interface circuit may estimate one or more communication metrics associated with the channel in the band of frequencies. Moreover, based at least in part on the one or more communication metrics, the interface circuit may determine a data rate for use in communication via the channel in the band of frequencies.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a first wireless device to select a channel to a second wireless device among a set of channels to the second wireless device shared by a set of wireless devices of the wireless network, and further transmit data to the second wireless device over the selected channel. The first wireless device can perform a measurement to determine a channel occupancy during a measurement period for a channel, wherein the measurement period includes a plurality of periodic transmission durations. The first wireless device can select a channel that is less occupied indicated by the channel occupancy of the channel. The first wireless device can further transmit data to the second wireless device over the selected channel in a transmission period after the measurement period.

Abstract: An interface circuit in an electronic device may contend for access to a shared communication channel on behalf of the electronic device and a recipient electronic device, where the access has a duration. Then, the electronic device may provide a schedule frame intended for the recipient electronic device that includes information that specifies one or more time slots during the duration that are associated with the recipient electronic device and one or more communication functions of the recipient electronic device in the one or more time slots. Moreover, the electronic device may provide a data frame with data intended for the recipient electronic device. In response, the electronic device may receive a response frame associated with the recipient electronic device, where the response frame is received during at least one of the one or more time slots.

Abstract: An access point transmits a trigger frame to a set of electronic devices in a wireless local area network (WLAN). The access point receives, from one or more electronic devices in a set of electronic devices, one or more requests to send data. In response, the access point transmits the trigger frame, which includes information specifying an ordered list of electronic devices in the set of electronic devices that are allowed to transmit. Subsequently, the access point sequentially receives one or more frames from the ordered list of electronic devices. After receiving a frame from the last electronic device in the ordered list of electronic devices or after an unused transmit opportunity of the last electronic device in the ordered list of electronic devices, the access point transmits a block acknowledgment to the ordered list of electronic devices.
