Patent number: 12289201Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for implementing multi-link aggregation and conditional inheritance in a first basic service set (BSS). In one aspect, an apparatus may establish a first communication link with a first station (STA) of the first BSS using a first frequency band. The apparatus may determine a first link profile for a second communication link by customizing one or more management elements of management information associated with the first communication link. The apparatus may configure a first non-inheritance element of the first link profile associated with the second communication link to indicate usage of at least one management element of the management information by the second communication link is disabled. The apparatus may generate a management frame that comprises at least the first link profile, and may output the management frame for transmission.Type: GrantFiled: May 2, 2022Date of Patent: April 29, 2025Assignee: QUALCOMM IncorporatedInventors: Yongchun Xiao, Abhishek Pramod Patil, Sandip HomChaudhuri, Ravi Gidvani, Alfred Asterjadhi, George Cherian

Patent number: 12250587Abstract: Methods, systems, and devices for wireless communications are described. A station (STA) may receive a first signal including an indication of a set of frequency channels for a set of target wake time (TWT) sessions that recur according to a service interval. In some examples, the first signal may indicate a respective frequency channel of the set of frequency channels for each TWT session of the set of target wake time sessions. Each TWT session of the set of TWT sessions may have an associated service period that the STA may be in an awake state. The STA may switch, for the first TWT session, from the first frequency channel to the second frequency channel. In some examples, based on the switching, the STA may communicate a signal during a service period associated with the first TWT session over the second frequency channel.Type: GrantFiled: July 10, 2023Date of Patent: March 11, 2025Assignee: QUALCOMM IncorporatedInventors: Srikant Kuppa, Sandip Homchaudhuri, Yongchun Xiao, Hao-Jen Cheng

Patent number: 12232059Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for analyzing management frames for multiple basic service sets (BSSs). In one aspect, a wireless node may obtain a first management frame from a wireless local area network (WLAN) apparatus, the WLAN apparatus operating multiple virtual access points (VAPs) respectively corresponding to multiple BSSs. The wireless node may determine whether the first management frame includes a BSS profile of a BSS associated with the wireless node based, at least in part, on an arrangement of a plurality of BSS profiles within one or more management frames. The wireless node may determine to further process the first management frame based, at least in part, on a determination that the first management frame includes the BSS profile of the BSS associated with the wireless node.Type: GrantFiled: November 13, 2023Date of Patent: February 18, 2025Assignee: QUALCOMM IncorporatedInventors: Abhishek Pramod Patil, Yongchun Xiao, Ravi Gidvani, Sandip HomChaudhuri, Pradeep Kumar Yenganti, Arul Davidson Emmanuel, James Simon Cho, Padmanabhan Venkataraman Karthic, George Cherian, Alfred Asterjadhi, Jouni Kalevi Malinen

Publication number: 20240163792Abstract: 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.Type: ApplicationFiled: November 8, 2023Publication date: May 16, 2024Inventors: Abdel Karim AJAMI, Abhishek Pramod Patil, Yongchun Xiao, Alfred Asterjadhi, George Cherian, Sai Yiu Duncan Ho, Yanjun Sun, Gaurang Naik
