  • Patent number: 11963155
    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.

  • Publication number: 20240097840
    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.

  • Publication number: 20240088958
    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.

  • Publication number: 20240090010
    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.

  • Publication number: 20240090046
    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.

  • Publication number: 20240089730
    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.

  • Publication number: 20240074475
    Abstract: A method of preparing a flavor composition containing D-allulose includes: (1) weighing D-allulose, mogroside, steviol glycoside and trichlorosucrose in parts by weight, and mixing them evenly to obtain a mixed powder; (2) degassing, compressing, and rolling the mixed powder, and extruding the raw materials into flakes; and (3) crushing and granulating the shaped flakes to obtain the flavor composition. D-allulose is used as the main raw material, and added high-intensity sweeteners as auxiliary raw materials. After the raw materials are mixed evenly, dry granulation is adopted, and the powder is degassed and pre-compressed by using the crystal water in the raw materials, and squeezed by a hydraulic roller to form a bonding force between the various sweetener molecules to form flakes, and the flakes are processed by processes such as crushing and granulating to obtain the flavor composition granules containing D-allulose with the various sweeteners integrated uniformly as a whole.

  • Patent number: 11924812
    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.

  • Publication number: 20240073739
    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.
