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: Methods, systems, and devices for wireless communication at a multi-link device are described. A first multi-link device (MLD) may communicate with a second MLD in accordance with the techniques depicted herein. For instance, the second MLD may transmit an indication of at least a portion of a beacon interval timeline for communications between the second MLD and one or more first MLDs on a first radio frequency link. In some examples, the beacon interval timeline may include at least one of a beacon transmit interval, and one or more service periods, channel access over a second radio frequency link being via the one or more service periods. A service period may be scheduled for communications on the second radio frequency link. The second MLD may then communicate in accordance with at least one of the beacon transmit interval and the one or more service periods.

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.

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 methods, components, devices and systems for providing information with respect to co-existence conditions. Some aspects more specifically relate to providing co-existence condition information via response messages. In some examples, co-existence condition information provided via a response message may indicate that a wireless communication device is experiencing a co-existence condition, may include information regarding the co-existence condition, or a combination thereof. Response messages utilized in carrying co-existence condition information may include messages made in response to a message from a peer wireless communication device via an existing or otherwise prior established messaging channel established for messaging of information other than co-existence condition information.

Abstract: This disclosure provides methods, devices and systems for protecting latency-sensitive communications, during restricted target wake time (r-TWT) service periods (SPs), from non-legacy STAs that do not support r-TWT operation. Some implementations more specifically relate to preventing STAs that are not members of an r-TWT SP from acquiring transmit opportunities (TXOPs) that would otherwise overlap with the start of the r-TWT SP. In some implementations, the AP may require all non-legacy STAs associated with its basic service set (BSS) to support r-TWT operation. In some other implementations, the AP may attempt to capture a wireless channel associated with the r-TWT SP within a fixed period preceding the r-TWT SP. In some other implementations, the AP may require all associated STAs to transmit a request-to-send (RTS) frame when attempting to acquire a TXOP. Still further, in some implementations, the AP may limit the duration of TXOPs acquired by non-member STAs.

Abstract: This disclosure provides methods and devices for managing the allocation of resources for uplink (UL) and downlink (DL) transmissions associated with a scheduled time period. In some implementations, a wireless station (STA) transmits, to an access point (AP), a request frame indicating a bandwidth or a quantity of spatial streams (or both) for the UL transmissions, and indicating a bandwidth or a quantity of spatial streams (or both) for the DL transmissions. In some instances, the request frame also may indicate the STA's intention to transmit UL data as duplicates carried on different communication links. The STA receives a trigger frame indicating that the STA is scheduled to transmit or receive data during the time period. The STA transmits data to, or receives data from, one or more other devices during the time period.

Abstract: This disclosure provides methods, components, devices and systems for wireless packet header protection. Some aspects more specifically relate to supporting header integrity checks to prevent processing of maliciously altered packet headers. In some examples, a wireless communication device may generate header integrity check information based on one or more fields of a header of a first data packet. The wireless communication device may generate, based on the header integrity check information, the first data packet or a second data packet. For example, the header of the first data packet may include the header integrity check information, or a value derived therefrom. Alternatively, the header integrity check information (or the derived value) may be included in a subsequently transmitted packet (e.g., the second data packet) A receiving device may use the received header integrity check information to perform a header integrity check before processing the header of the first data packet.
