Abstract: This disclosure provides methods, devices and systems for protecting latency-sensitive communications during restricted target wake time (r-TWT) service periods (SPs). Some implementations more specifically relate to coordinated scheduling of r-TWT SPs between OBSSs. In some aspects, a first AP may coordinate with a second AP in scheduling r-TWT SPs so that latency-sensitive traffic in a first BSS does not interfere or collide with latency-sensitive traffic in a second BSS overlapping the first BSS. In some implementations, the first and second APs may schedule their respective r-TWT SPs to be orthogonal in time. In some other implementations, the first and second APs may schedule their r-TWT SPs to overlap in time, while allocating coordinated resources to concurrent or overlapping latency-sensitive traffic in the first and second BSSs (such as in accordance with one or more multi-AP coordination techniques).

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) may transmit a packet, at the beginning of a restricted TWT SP, that signals all non-member wireless stations (STAs) to defer access to the wireless medium for at least a threshold duration. Upon receiving the packet, any non-member STAs that are associated with the AP may set their network allocation vectors (NAVs) according to the duration indicated by a duration field of the received packet. In some implementations, low-latency STAs that are members of the TWT SP may not set their NAVs according to the duration field of the received packet. Instead, the low-latency STAs may access the wireless medium before the NAVs associated with the non-member STAs expire.

Abstract: This disclosure provides methods, components, devices and systems for signaling mechanisms for multi-hop channel sounding for relay operation. Some aspects more specifically relate to frame addressing and transmission opportunity (TXOP) or service period (SP) sharing to facilitate a multi-hop channel sounding within a single TXOP or SP. An originating device may transmit a first frame indicating identifying information corresponding to multiple other wireless communication devices to initiate a multi-hop channel sounding involving the multiple other wireless communication devices. For example, the originating device may include, in the first frame, identifying information corresponding to a satellite access point (AP) and identifying information corresponding to an end device with which the originating device may communicate via the satellite AP. In accordance with the multi-hop channel sounding, the originating device may receive, collectively via one or more frames, channel information associated with each hop between the originating device and the end device.

Abstract: In some implementations, a first access point (AP) selects one or more other APs for participation with the first AP in a coordinated access point transmission session. The first AP obtains a transmission opportunity (TXOP), and transmits a frame indicating scheduling information for uplink (UL) or downlink (DL) transmissions to or from the selected APs, the scheduling information indicating a respective start time for the UL or DL transmissions to or from the selected APs, at least two of the start times being offset from one another by a time period associated with decoding a preamble of a wireless packet. The first AP transmits or receives wireless packets to or from one or more associated stations (STAs) at least partially concurrently with the transmission or reception of wireless packets by the selected APs to or from their respective associated STAs based on the scheduling information.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless communication device may determine a first set of parameters for communicating with a second wireless communication device within a first set of time intervals, the first set of parameters associated with a beamforming procedure. The first wireless communication device may predict, based on inputting the first set of parameters to a machine learning model, a second set of parameters corresponding to a second set of time intervals in the future after the first set of time intervals. The first wireless communication device may select a beamforming configuration for communications between the first wireless communication device and the second wireless communication device based on the second set of parameters, and may communicate with the second wireless communication device within the second set of time intervals in accordance with the beamforming configuration.

Abstract: This disclosure provides methods and devices for introducing a power save protocol (for example, a lower power mode) for a multi-link devices (MLDs). Some aspects more specifically relate to reducing power consumption in an access point (AP) MLD, and more particularly, to a power save protocol (or a lower power mode) for an AP MLD. In some aspects, an AP MLD may initiate a lower power mode to save power for as long as possible while still maintaining minimal receive (RX) and transmit (TX) functionality. When requested by an associated station (STA), the AP MLD may then transition from the lower power mode to a higher power mode with full RX and TX functionality with a minimal delay. The described techniques may also account for trade-offs and constraints which arise due to different use cases and scenarios as well as different device configurations.

Abstract: This disclosure provides methods, components, devices and systems for use of a reinforcement learning (RL) model to obtain one or more parameters associated with a channel access procedure. Some aspects more specifically relate to mechanisms according to which a wireless communication device may receive information associated with the RL model and transmit a protocol data unit (PDU) during a slot that is based on an output of the model. The wireless communication device may use the RL model to perform a distributed channel access procedure in accordance with the information and may further transmit the PDU, during the slot that is based on the output of the RL model, in accordance with the distributed channel access procedure. The information associated with the RL model may indicate or configure the RL model or may indicate whether the wireless communication is allowed to retrain the RL model.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for wireless communication, including coordinated time domain multiple access (C-TDMA) among access points (APs) with different channels. In one aspect, while using C-TDMA, a first AP may receive a control message with scheduling information for a transmission opportunity (TXOP) from a second AP, which is the TXOP owner. The second AP may operate in a certain bandwidth, and first AP may operate in an overlapping portion of the same bandwidth, and also a different portion of bandwidth. The scheduling information may indicate a portion of the TXOP for the first AP to use during the TXOP. During the portion of the TXOP for the first AP, the first AP may perform a clear channel assessment (CCA) for the overlapping and non-overlapping portions, and transmit on both the overlapping and different bandwidths during the TXOP.

Abstract: This disclosure provides systems, methods, and apparatus for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) receives a request frame from a wireless station (STA) associated with a client device via a peer-to-peer (P2P) link, the request frame indicating that the STA intends to exchange P2P communications with the client device during a r-TWT SP scheduled on a wireless medium. The AP obtains a transmission opportunity (TXOP) on the wireless medium during the r-TWT SP, the request frame identifying the client device. The AP transmits a trigger frame on the wireless medium responsive to obtaining the TXOP, the trigger frame allocating a portion of the obtained TXOP for P2P communications between the STA and the client device, wherein at least one of the response frame or the trigger frame indicates a Network Allocation Vector (NAV) exception for the client device.
