Publication number: 20240106584Abstract: Payload transmission of multiple stations on a single resource unit may be performed. New and/or updated signaling may be introduced to enable a transmitter, e.g., an access point (AP), to include information/signaling in the preamble or in other frames. A receiver (e.g., a wireless station) that receives this information/signaling may accordingly determine in which RU it should decode to receive its allocated data or payload, allowing multiple receivers or STAs to share a single resource unit (RU). The new/updated signaling may include modified hybrid downlink multiuser signaling in Ultra High Reliability Signal (UHR-SIG), a group association identifier (gAID), a predefined special AID corresponding to an RU with use of a Bloom filter, multiple predefined special AIDs each corresponding to a non-overlapping group of wireless stations, and/or signaling announcing time sharing of single RUs.Type: ApplicationFiled: September 22, 2023Publication date: March 28, 2024Inventors: Jinjing Jiang, Lochan Verma, Jarkko L. Kneckt, Yong Liu, Ahmad Reza Hedayat, Tianyu Wu, Zhou Lan

Publication number: 20240080660Abstract: An electronic device (such as an access point) that receives a modified response frame is described. During operation, an interface circuit in the electronic device may provide a trigger frame addressed to a second electronic device, where the trigger frame includes a trigger-frame variant that is compatible with an IEEE 802.11 standard (such as IEEE 802.11ax or a subsequent IEEE 802.11 standard). Then, the interface circuit may receive a modified response frame associated with the second electronic device, where the modified response frame is different from a response frame associated with the trigger frame specified by the IEEE 802.11 standard. When the second electronic device indicates support for the modified response frame during association with the electronic device, the interface circuit may define parameters associated with the modified response frame in an association response.Type: ApplicationFiled: August 10, 2023Publication date: March 7, 2024Inventors: Jarkko L.

Publication number: 20240073794Abstract: An electronic device (such as an access point) that receives a modified response frame is described. During operation, an interface circuit in the electronic device may provide a management frame addressed to a second electronic device. Then, the interface circuit may provide a trigger frame addressed to the second electronic device, where the trigger frame includes a trigger-frame variant that is compatible with an IEEE 802.11 standard.

Patent number: 11916710Abstract: The present invention discloses a data transmission method, apparatus, and system, and an access point. The method includes: transceiving data of a data portion in an uplink OFDMA PPDU scheduled by an access point AP on a corresponding allocated frequency resource unit RU, determining one or more fundamental channel units on which the allocated frequency resource unit RU is located, and transceiving at least some fields in a common signaling portion in the uplink OFDMA PPDU on the determined one or more fundamental channels. In this way, one or more fundamental channels for transceiving at least some fields in a common signaling portion in an uplink OFDMA PPDU are determinate, and another user can transceive data on another idle fundamental channel, thereby improving channel utilization. In addition, multiple users can simultaneously transceive data on multiple fundamental channels, thereby improving a service transmission rate.Type: GrantFiled: May 23, 2022Date of Patent: February 27, 2024Assignee: Huawei Technologies Co., Ltd.Inventors: Le Liu, Zhou Lan

Patent number: 11417021Abstract: A tissue analysis system and method for the spectral deconvolution of a RGB digital image obtained from a stained biological tissue sample, by estimating the stain component images that are obtained from a staining system configuration, where the reference stain vectors are assumed to be sampled from a known color distribution. The prior knowledge of stain variability of the staining system is adopted as initial reference stain vectors and statistical distribution of their variability. Based on the initial reference stain vectors distribution, the tissue analysis system determines both the reference stain vectors and stain component images of the input image. The image is then deconvoluted based on the reference stain vectors and stain component images.Type: GrantFiled: January 31, 2020Date of Patent: August 16, 2022Assignee: Ventana Medical Systems, Inc.Inventors: Srinivas Chukka, Zhou Lan

Publication number: 20220256455Abstract: When performing data transmission with a first station in a bandwidth power saving mode by using an operating channel of the first station, an access point performs data transmission with a second station by using an operating channel of the second station. Therefore, even if the operating channel of the first station includes a primary channel, the access point can still perform data transmission with the second station by using another channel. Further, for the access point, although the operating channel of the first station occupies only a part of available bandwidth resources of the access point, the access point can still perform data transmission with the second station by using a remaining channel.Type: ApplicationFiled: April 27, 2022Publication date: August 11, 2022Inventors: Yanchun LI, Zhou LAN, Yunbo LI
