Abstract: Coordinated spatial reuse and frequency utilization techniques in overlapping basic service set environments for IEEE 802.11be and beyond. The techniques involve transmit power and frequency allocation methods designed for coordinated spatial reuse between multiple access points, considering interference from stations and access points, as well as occupied bandwidth. In one embodiment, an access point generates a trigger frame with punctured bandwidth or good subchannel information to coordinate spatial reuse, enabling a station to transmit an uplink data packet using specified parameters. In another embodiment, a station receives a trigger frame with punctured bandwidth information and transmits an uplink data packet excluding the puncture portion to avoid interference. The techniques allow transmissions in multiple basic service sets to coexist without harmful interference, improving throughput and frequency utilization in dense wireless networks. Although primarily described in the context of IEEE 802.11, the techniques can be applied to other wireless networks.

Abstract: A method by a wireless transmitting device for distinguishing between a quality of service (QoS) management frame and a non-QoS management frame is described. The method includes generating a frame that includes a frame header, wherein the frame header includes a frame control field, wherein the frame control field includes a partial traffic identifier or subtype (PTID/subtype) subfield, wherein the PTID/subtype subfield indicates whether the frame is a quality of service (QoS) management frame or a non-QoS management frame and transmitting the frame through a wireless medium.

Abstract: Dynamic Transmission Opportunity (TXOP) sharing between overlapping Basic Service Sets (BSSs) in wireless networks. A sharing Access Point (AP) initiates a process by generating and wirelessly transmitting a control frame to allocate its TXOP to a shared AP in an overlapping BSS. Subsequently, the sharing AP receives a return TXOP frame from the shared AP, indicating the return of any unused TXOP portion. The sharing AP then has the flexibility to either resume its own transmissions using the returned TXOP or reallocate it to an alternative AP. Using the techniques in dense wireless networking environments enables efficient spectrum utilization through dynamic TXOP allocation and reclamation. The techniques address challenges of resource management in multi-AP scenarios, improving overall network performance and reducing interference in overlapping coverage areas.

Abstract: Disclosed herein is a method performed by a station (STA) in a wireless network to access a non-primary channel. The method includes determining a maximum supportable bandwidth of a primary transmission opportunity (TXOP) established in a primary channel, responsive to a determination that the maximum supportable bandwidth of the primary TXOP is smaller than a maximum supportable bandwidth of the STA, establishing a secondary TXOP in the non-primary channel, and transmitting a data frame to a second STA during the secondary TXOP in the non-primary channel.
