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 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: 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.
