The first wireless device may obtain a second TXOP to transmit or receive, via a second primary channel, a second signaling indicating a second reservation of the second TXOP. The ending time of the second TXOP may occur prior to an ending time of the first reservation and prior to a transition delay associated with a communication event scheduled on the first subset of channels or a second subset of channels.

Abstract: This disclosure provides methods, components, devices and systems for techniques for end-to-end operations between a first wireless station (STA) and a second STA via a wireless access point (AP). Some aspects more specifically relate to indicating one or more quality of service (QOS) parameters to the AP, sharing transmission opportunities (TXOPs) between the first STA and the AP, or both.

Abstract: This disclosure provides methods, components, devices and systems for service period based coordinated spatial reuse. Some aspects relate to long term signaling to reduce the amount of signaling while achieving the gain associated with coordinated spatial reuse as compared to distributed spatial reuse. A first wireless device associated with a first basic service set (BSS) may transmit a beacon indicating a set of service periods designated for spatial reuse and an interference threshold. A second wireless device associated with a second BSS may receive the beacon and may communicate with one or more other wireless devices associated with the second BSS during the set of service periods designated for spatial reuse in accordance with the indicated interference threshold. Accordingly, the wireless devices in the second BSS may communicate at a power level that causes an acceptable level of interference at the first BSS.

Abstract: This disclosure provides methods, components, devices and systems for enabling coordinated multiple access on multiple primary channels. Some aspects more specifically relate to inter access point (AP) coordination to share a portion of a transmission opportunity (TXOP). A first AP may transmit a first signal on a secondary primary channel conveying an indication that a portion of the TXOP is available for sharing. The second AP may respond with a confirmation on the secondary primary channel that the second AP is tuned to the secondary primary channel. Accordingly, the second AP may transmit a second signal on the secondary primary channel to the first AP indicating that the portion of the TXOP is available for use. The second AP may use the portion of the TXOP to communicate with one or more station(s) on the secondary primary channel.

Abstract: This disclosure provides methods, components, devices and systems for negotiation for coordinated medium access between wireless devices. Some aspects more specifically relate to techniques for negotiation between wireless devices for medium access. In some examples, wireless devices may transmit requests and responses to negotiate for conflicting medium access periods between wireless devices, where the wireless devices may be in different basic service sets (BSSs). For example, wireless devices such as wireless access points (APs) may broadcast a reservation of medium access periods. In some examples, a first wireless device may transmit a request to negotiate medium access periods with a second wireless device, and the second wireless device may transmit a response to the request. For example, the request to negotiate may request that the wireless devices mutually honor or respect (for example, comply with) one or more of the medium access period reservations of each wireless device.

Abstract: This disclosure provides methods, components, devices and systems for multi-hop support for coordinated medium access. Some aspects more specifically relate to one or more mechanisms according to which an access point (AP) may indicate how many hops a medium access schedule is to be re-announced throughout a wireless network. In some examples, a first AP may select a medium access schedule and may transmit timing information indicative of communication periods associated with the medium access schedule and a value associated with a multi-hop propagation of the timing information. A second AP may receive the timing information and the value and may selectively transmit the timing information in accordance with the value. For example, if the value is indicative of greater than or equal to a threshold hop count value, the second AP may propagate the timing information associated with the communication periods of the first AP.
