Patent number: 12047873Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for protecting latency-sensitive communications among multi-link devices (MLDs). An access point (AP) MLD may establish multiple communication links with a non-AP MLD and schedule a restricted target wake time (r-TWT) service period (SP) on one of the links (the “r-TWT link”). In some aspects, when a transmit opportunity (TXOP) acquired on a non-r-TWT link overlaps the r-TWT SP, the TXOP may be extended to support an exchange of latency-sensitive traffic on the non-r-TWT link. In some other aspects, any TXOPs occurring on non-r-TWT links may be terminated prior to the start of the r-TWT SP so that latency-sensitive traffic can be exchanged on the r-TWT link during the SP. An AP MLD also may schedule SPs on multiple communication links. In some aspects, the AP MLD may transfer a TWT agreement between the communication links.Type: GrantFiled: December 22, 2021Date of Patent: July 23, 2024Assignee: QUALCOMM IncorporatedInventors: Gaurang Naik, Abdel Karim Ajami, Alfred Asterjadhi, George Cherian, Abhishek Pramod Patil, Sai Yiu Duncan Ho, Yanjun Sun

Publication number: 20240237065Abstract: This disclosure provides methods, components, devices and systems for coordinated spatial reuse (C-SR) framework for ultra-high reliability (UHR). Some aspects more specifically relate to one or more mechanisms according to which access points (APs) may coordinate with each other in accordance with a C-SR framework. In some implementations, a first access point (AP) may conditionally share a transmission opportunity (TXOP) for the first AP with a second AP in accordance with an interference management procedure between the first AP (and any one or more client devices of the first AP) and the second AP (and any one or more client devices of the second AP). For example, the first AP and the second AP may support one or more frame exchanges associated with an interference measurement and the second AP may share the TXOP if the second AP satisfies a transmit power constraint associated with the interference measurement.Type: ApplicationFiled: October 24, 2022Publication date: July 11, 2024Inventors: Abdel Karim Ajami, Yanjun Sun, George Cherian, Alfred Asterjadhi, Abhishek Pramod Patil, Sai Yiu Duncan Ho, Gaurang Naik

Publication number: 20240236844Abstract: 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.Type: ApplicationFiled: October 19, 2022Publication date: July 11, 2024Inventors: Alfred Asterjadhi, George Cherian, Abhishek Pramod Patil, Abdel Karim Ajami, Gaurang Naik, Yanjun Sun, Sai Yiu Duncan Ho

Publication number: 20240224259Abstract: Methods, systems, and devices for wireless communications are described. An access point (AP) may support sharing a portion of a transmission opportunity (TXOP) with another AP using an AP-specific AID. For example, a first AP may obtain a TXOP associated with communication via a wireless channel. The first AP may determine to allocate a portion of the TXOP to a second AP. To allocate the portion of the TXOP to the second AP, the first AP may transmit a frame that indicates one or more resources of the TXOP that are allocated to an AP identified by the frame. To identify the second AP, the frame may include an AP-specific AID selected by or otherwise assigned to the second AP. The second AP may communicate one or more frames during the portion of the TXOP allocated to the second AP.Type: ApplicationFiled: January 3, 2023Publication date: July 4, 2024Inventors: Yanjun Sun, Abhishek Pramod Patil, Alfred Asterjadhi, Sai Yiu Duncan Ho, George Cherian, Abdel Karim Ajami, Gaurang Naik

Publication number: 20240224257Abstract: 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.Type: ApplicationFiled: March 12, 2024Publication date: July 4, 2024Inventors: Yanjun SUN, George CHERIAN, Alfred ASTERJADHI, Sai Yiu Duncan HO, Abhishek Pramod PATIL

Publication number: 20240214996Abstract: 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.Type: ApplicationFiled: January 31, 2024Publication date: June 27, 2024Inventors: Stephen Jay SHELLHAMMER, Sameer VERMANI, Jialing Li CHEN, Bin TIAN, Alfred ASTERJADHI, Yanjun SUN
