Publication number: 20240097840Abstract: 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.Type: ApplicationFiled: September 16, 2022Publication date: March 21, 2024Inventors: Alfred ASTERJADHI, Abhishek Pramod PATIL, George CHERIAN, Yanjun SUN, Sai Yiu Duncan HO, Gaurang NAIK, Abdel Karim AJAMI

Publication number: 20240090010Abstract: 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.Type: ApplicationFiled: September 12, 2022Publication date: March 14, 2024Inventors: Abdel Karim Ajami, Sai Yiu Duncan Ho, Alfred Asterjadhi, George Cherian, Abhishek Pramod Patil, Yanjun Sun, Gaurang Naik, Naveen Gangadharan, Nathaniel David Houghton, Srinivas Katar, Xiaolong Huang

Patent number: 11926993Abstract: This disclosure provides methods, devices and systems for sharing resources of a wireless medium. Various implementations relate generally to coordinated transmit power control for sharing time and frequency resources of a wireless medium. Particular implementations relate more specifically to coordinated access point spatial-reuse-multiple-access techniques for sharing the time and frequency resources of a transmission opportunity. According to such techniques, an access point that wins contention and gains access to the wireless medium for the duration of a transmission opportunity may limit the transmit powers of the access points selected to share the time and frequency resources such that interference from the selected access points does not prevent stations associated with the winning access point from successfully decoding packets transmitted by it.Type: GrantFiled: September 13, 2022Date of Patent: March 12, 2024Assignee: QUALCOMM IncorporatedInventors: Lochan Verma, George Cherian, Maarten Menzo Wentink

Publication number: 20240080146Abstract: 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.Type: ApplicationFiled: November 13, 2023Publication date: March 7, 2024Inventors: George Cherian, Alfred Asterjadhi, Abhishek Pramod Patil, Bin Tian, Sameer Vermani

Publication number: 20240073739Abstract: 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.Type: ApplicationFiled: February 28, 2023Publication date: February 29, 2024Inventors: Srinivas KATAR, George CHERIAN, Abhishek Pramod PATIL, Sai Yiu Duncan HO, Alfred ASTERJADHI, Gaurang NAIK, Yanjun SUN, Abdel Karim AJAMI
