Abstract: This disclosure provides methods, devices and systems for synchronized channel access. Some implementations more specifically relate to facilitating coexistence among wireless communication devices that support synchronized channel access and those that do not. A group of access points may schedule periodically recurring, synchronized channel access periods by periodically transmitting quiet elements. The quiet elements establish recurring quiet periods during which legacy devices are not permitted to transmit. In some implementations, an access point may transmit one or more quiet override elements each associated with a respective quiet element and indicating to other access points supporting synchronized channel access that they are permitted to contend for access during the respective quiet period.

Abstract: This disclosure provides methods, devices and systems for sharing resources of a wireless medium. Particular implementations relate more specifically to coordinated AP (CAP) time-division-multiple-access (TDMA) and orthogonal-frequency-division-multiple access (OFDMA) techniques for sharing the time or frequency resources of a transmission opportunity (TXOP). According to such techniques, an AP that wins contention and gains access to the wireless medium for the duration of a TXOP may share its time or frequency resources with other selected APs. To share its resources, the winning AP may partition the TXOP into multiple time or frequency segments each including respective time or frequency resources representing a portion of the TXOP, and allocate each of the time or frequency segments to itself or to one of the selected APs.

Abstract: Aspects relate to multi-link communication. In some examples, a communication frame carries a multi-link information element (ML IE). The ML IE includes a bitmap and one or more information sub-elements. In some examples, the bitmap indicates the links of a set of radio links to which the information sub-elements apply. In some examples, a frame may carry multiple ML IEs. In some examples, different ML IEs in the same frame may include the same bitmap, where the different ML IEs may carry different information sub-elements for the radio links indicated by the bitmap. In some examples, an ML IE serves to indicate that information sub-elements that are located in the frame body of the frame at a location that precedes the ML IE in the frame body apply to different radio links than the radio links indicated by the bitmap of the ML IE.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device (e.g., station (STA), access point (AP)) may transmit to a second wireless device during a service period, an initiating frame using a transmit beam that is based on a first beam training procedure performed between the devices prior to the service period. The first wireless device may perform a second beam training procedure during the service period based on an absence of a response frame from the second wireless device, based on an indication within the response frame received from the second wireless device, or based on identification of a change in a wireless channel relative to a previous beam training interval or previous service period. The first wireless device may then communicate one or more messages with the second wireless device using one or more beams that are based on the second beam training procedure.

Abstract: This disclosure provides methods, devices and systems that facilitate mobility of wireless communication devices configured for multi-link operation (MLO). Particular aspects more specifically relate to facilitating fast basic service set (BSS) transitions by wireless communication devices that support MLO. For example, some aspects provide support for station (STA) multi-link device (MLD) roaming between access point (AP) MLDs, from an AP MLD to a non-MLO AP, or from a non-MLO AP to an AP MLD. In some aspects, a STA MLD may be configured to use a medium access control (MAC) service access point address (MAC-SAP address) of the AP MLD when re-associating or communicating with a legacy AP or with an AP MLD. In such aspects, the MAC-SAP address may be used by all STAs of the non-AP MLD for fast BSS transitions.

Abstract: Techniques related to wireless communication are disclosed. Some aspects of the disclosure relate to devices and methods for improving a quality of service (QoS) by reporting near-real-time feedback relating to a delay experienced by packets queued for transmission, and dynamically scheduling a wireless station to transmit and meet its QoS. A wireless station (STA) obtains one or more packets for transmission, the packets being associated with a delay condition. The STA outputs for transmission a delay status report that includes information relating to the delay condition associated with the one or more packets. In response, the STA obtains a resource allocation for transmission of the one or more packets according to the information relating to the delay condition. Other aspects, embodiments, and features are also claimed and described.

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.

In one aspect, a first wireless communication device may generate a first frame that includes at least a first aggregated media access control protocol data unit (A-MPDU). The first A-MPDU may include one or more media access control protocol data units (MPDUs). The first wireless communication device may set a first recipient address (RA) field to a first value in a first MPDU, and set a first field in the first MPDU to a second value that represents an identifier of a second wireless communication device. In one aspect, the first wireless communication device may set a second field in the first MPDU to a third value that represents an identifier of a third wireless communication device. The wireless communication device may output the first frame for transmission to at least the second and third wireless communication devices.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for preventing or reducing cross-network interference associated with a coordinated transmission on a wireless channel. A first access point (AP) of a first basic service set (BSS) and a second AP of a second BSS can concurrently use the wireless channel using a coordinated transmission during a portion of a transmission opportunity (TXOP). The TXOP owner (such as the first AP) may allocate a resource assignment to the second AP such that the resource assignment is conditionally available for use by the second AP in a coordinated transmission. The condition may prevent the resource assignment from being used by the second BSS when its use would cause interference to the first BSS. The condition may be based on a transmit power for downlink communication or uplink communication in the second BSS.

Abstract: This disclosure provides methods, devices and systems for generating enhanced trigger frames. Some implementations more specifically relate to trigger frame designs that support gains in data throughput achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an enhanced trigger frame may be used to solicit a non-legacy trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data unit (PPDU) from one or more wireless stations (STAs). In some implementations, the enhanced trigger frame may be configurable to support multiple versions of the IEEE 802.11 standard. For example, an enhanced trigger frame may be configured in accordance with a legacy trigger frame format or a non-legacy trigger frame format. Thus, when configured in accordance with the legacy trigger frame format, the enhanced trigger frame can also be used to a legacy TB PPDU from one or more STAs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may perform packet detection or energy detection on a primary channel using a first packet detector. The wireless device may perform packet detection or energy detection on a first non-primary channel using a second packet detector. The wireless device may transmit a packet on the first non-primary channel based on packet detection for the primary channel or packet detection for the first non-primary channel. Numerous other aspects are described.

Abstract: Aspects are provided for BTM-based load balancing. Various aspects relate generally to a method of load balancing where an AP multi-link device (MLD) recommends that a non-AP MLD move to an indicated set of links of the AP MLD and operate on the indicated set of links without purging context between the AP MLD and the non-AP MLD. In some examples, if the non-AP MLD does not comply, then the non-AP MLD may face disassociation from the AP MLD. Some aspects more specifically relate to recommending that the non-AP MLD move to an indicated set of links of a different AP MLD and operate on the indicated set of links of the different AP MLD after performing a multi-link setup with the different AP MLD. In some examples, the AP MLD may then disassociate from the non-AP MLD.
