Abstract: A configuration device is disclosed for configuring a network device in a communication network. The configuration device initiates pairing operations with the network device via a short-range communication connection. The configuration device determines whether the network device is in a registered state or an unregistered state. If the configuration device determines that the network device is in the unregistered state, the configuration device establishes a secure short-range communication channel between the configuration device and the network device. The configuration device transmits a network key to the network device via the secure short-range communication channel for configuring the network device to communicatively connect to the communication network. If the configuration device determines that the network device is in the registered state, the configuration device determines whether to unregister the network device.

Abstract: A first access point (AP) of an AP multi-link device (MLD) is associated with a first communication link, and one or more secondary APs of the AP MLD are associated with one or more respective secondary communication links of the AP MLD. The first AP of the AP MLD generates a frame including a first change sequence field and one or more secondary change sequence fields. The first change sequence field indicates a presence or absence of a critical update associated with the first communication link, and each of the one or more secondary change sequence fields indicates a presence or absence of a critical update associated with a corresponding secondary communication link of the AP MLD. The first AP of the AP MLD transmits the frame over the first communication link of the AP MLD to a station (STA) of a STA MLD.

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.

Abstract: Aspects of the present disclosure generally relate to wireless communications and, more particularly, to techniques for managing multi-link communications. Some aspects of the present disclosure provide techniques for configuring data unit and control response transmissions on multiple links. The data unit and control responses may be configured such that a control response transmission does not overlap with a data unit reception at a station that is without simultaneous transmission and reception capability.

Abstract: Certain aspects of the present disclosure relate to wireless communications. According to certain aspects, a method that may be performed by an access point (AP) includes outputting, for transmission to an access point (AP), a request to associate with the AP, wherein the request is encrypted with a first set of one or more keys; obtaining, from the AP, a response to the request; decrypting the response, based on the first set of keys, to obtain a second set of one or more keys; and using the second set of keys for secure data exchange with the AP.

Abstract: This disclosure provides methods, components, devices and systems for extending target wake time (TWT) frame functionality. Some aspects more specifically relate to accommodating TWT wake intervals that do not satisfy threshold TWT wake intervals. In some examples, a first wireless communication device configures at least one of: one or more subfields of a field or one or more fields of an element that include TWT information in a TWT frame, where the subfield(s) or field(s) indicate a presence or absence of at least one optional field in the TWT frame, or an optional element in the TWT frame. The device then transmits the TWT frame to a second wireless communication device. After the second device receives this TWT frame, this device executes one or more operations associated with a TWT schedule or service period based at least in part on the configured subfield(s) or field(s) or the configured optional element.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for identifying frames or packets of data that were received in error (such as incorrectly decoded or not received at all) by a receiving device for purposes of retransmission. In one aspect, a wireless device may form a number of frames for wireless transmission. Each of the frames may include a frame header and may be associated with a unique sequence number. In some implementations, for each of the frames, the wireless device may embed at least a portion of the unique sequence number into a portion of a control field or a delimiter field of the frame header. In some other implementations, for each of the frames, the wireless device may signal at least a portion of the unique sequence number using bit locations unassociated with a sequence number field of the frame header.

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: Methods, systems, and devices for wireless communications are described. A first wireless device may communicate signaling with a second wireless device based on establishing a radio frequency link, the signaling indicating the first wireless device and the second wireless device are to skip performance of a beam training procedure, or indicating a selection between a first beam training procedure associated with the radio frequency link and a second beam training procedure associated with the radio frequency link. The first wireless device may then communicate one or more messages with the second wireless device via the radio frequency link using a beam, where the beam is based on whether the signaling indicates the first wireless device and the second wireless device are to skip performance of the beam training procedure, or indicates the selection between the first beam training procedure and the second beam training procedure.
