Abstract: This disclosure provides methods, components, devices, and systems that support information exchanges for coordinated access point (CAP) operations. Some aspects more specifically relate to transmitting and receiving CAP-specific parameters to facilitate transmit opportunity (TXOP) sharing between a first access point (AP) and one or more second APs. For example, the first AP (such as a sharing AP) may use CAP-specific parameters provided by the one or more second APs (such as shared APs) to determine a CAP sharing schedule for a TXOP. The CAP-specific parameters may include static capability parameters and dynamic parameters. The static capability parameters may include supported CAP modes, association identifiers (AIDs), and processing times, while the dynamic parameters may include medium access demands, traffic priority information, and service period information. The first AP may advertise the CAP sharing schedule to the one or more second APs via an announcement frame.

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: This disclosure provides methods, components, devices, and systems for enhanced downlink (DL) data delivery. Some aspects more specifically relate to reducing the latency and power consumption associated with delivering DL buffered units (BUs) to stations (STAs) in an enhanced delivery mode. In some implementations, an access point (AP) may transmit an indication of queue information associated with one or more pending DL BUs for a STA. The AP may identify a set of operational parameters to use for transmission of the one or more pending DL BUs in accordance with the queue information. Likewise, the STA may identify a set of operational parameters to use for reception of the one or more pending DL BUs in accordance with the queue information. The AP may transmit the one or more pending DL BUs to the STA in accordance with the queue information and the set of operational parameters.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for coordinated scheduling of service periods (SPs). In some aspects, an access point (AP) may receive timing information indicating an SP associated with an overlapping basic service set (OBSS) and may transmit, to its associated STAs, coordinated timing information indicating the timing of the SP in relation to its timing synchronization function (TSF) timer. In some aspects, the AP may adjust the timing information to account for an offset between its TSF timer and a TSF timer associated with the OBSS. In some other aspects, the AP may synchronize its TSF timer with the TSF timer associated with the OBSS. The AP may further communicate with the STAs based on the coordinated timing information. For example, the AP may schedule communications with the STAs to be orthogonal to communications in the OBSS during the SP.

In certain aspects, the disclosure provides methods for transmitting and receiving, between the AP and one or more STAs, an indication of an operating band switch. In some examples, the transmitting and receiving may use non-legacy elements configured to provide information about the operating band switch.

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.

Abstract: This disclosure provides methods, components, devices and systems for signaling mechanisms for low latency and low complexity relay designs. Some aspects more specifically relate to an end-to-end (E2E) relay framework according to which a satellite access point (AP) may relay one or more protocol data units (PDUs) and a block acknowledgment (BA) associated with the one or more PDUs between a client device and a root AP within a single transmission opportunity (TXOP). In some implementations, the satellite AP may refrain from performing operations associated with reordering and retransmitting as part of the relay. In some other implementations, the satellite AP may perform some amount of retransmissions in accordance with a time duration of the TXOP. The root AP, the satellite AP, and the client device may support an end-to-end encryption of both the set of PDUs and the BA associated with the set of PDUs.

Abstract: This disclosure provides methods, components, devices and systems for packet duplication for data frames in a wireless local area network (WLAN). Some aspects more specifically relate to decoding duplicate packets that include data frames. An access point (AP) may transmit two or more physical layer protocol data units (PPDUs) that are duplicates of each other while operating in a duplicate data packet mode. A station (STA) may include one or more decoders configured to decode the duplicate PPDUs cumulatively or separately based on a decoding mode. The AP and the STA may exchange frames to dynamically enable or disable the duplicate data packet mode. The duplicate PPDUs may include one or more bits configured to indicate that the PPDU is a duplicate. The STA may decode at least one of the duplicate PPDUs and transmit a feedback message responsive to at least a portion of one of the duplicate PPDUs.

The assistance information may include a first indication to assist the first wireless device with accessing a second channel for the purpose of communicating with a third wireless device. In some implementations, the first indication may provide the first wireless device with timing information, bandwidth-related information, STA service information, synchronization information, transmit opportunity (TXOP) sharing information, or a combination thereof.

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 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 systems and methods for requesting wireless resources for peer-to-peer (P2P) communications.

The wireless communication device receives a trigger frame allocating a portion of the TXOP for the P2P communications, and transmits or receives P2P data to or from the client device over the wireless medium during the allocated portion of the TXOP. In some instances, the MAC header of the frame includes a Quality-of-Service (QOS) Control field carrying the request. In some other instances, the MAC header of the frame includes an Aggregated-Control (A-Control) subfield carrying the request.

In some implementations, a wireless communication device may coordinate timing information with one or more other APs and may inform a set of stations (STAs) of the coordinated timing information, where a configured set of identifiers (IDs) may be used to differentiate which timing information pertains to which AP and inform how the set of STAs are expected to parse the coordinated timing information. Additionally, or alternatively, wireless communication devices may exchange one or more public action frames to facilitate AP-to-AP coordination, where such one or more public action frames may be specifically associated with providing information pertaining to coordinated medium access.
