Patent number: 11974342Abstract: This application discloses a multi-link establishment method and a related device. A multi-link association response frame carries radio bitmap information, to indicate an AP allowed to be associated with a radio of a STA MLD or a link allowed to be established by using a radio of a STA MLD, so that the radio subsequently switches between different APs or links. The multi-link association response frame carries link establishment status information, to indicate a link establishment status of each link that the STA MLD requests to establish, so that multi-link establishment is more flexible. The multi-link association response frame carries reassociation information, to indicate whether each parameter in association configuration information is reserved, so that a problem that signaling overheads are relatively large due to a reassociation operation is avoided. It can be learned that, in the multi-link establishment method, the foregoing information is carried to improve multi-link establishment flexibility.Type: GrantFiled: April 14, 2023Date of Patent: April 30, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Guogang Huang, Yunbo Li, Ming Gan, Yuchen Guo

Patent number: 11956842Abstract: Embodiments of this application relates to a multi-link communication setup method and a related apparatus. The method includes: a non-AP MLD sends an association request frame on a first link, to request multi-link setup. An AP MLD returns an association response frame on the first link, to notify whether multi-link setup succeeds. The AP MLD sets a second status code field of a multi-link element of the association response frame to a newly defined value, to indicate that a cause why a link is not accepted is that the first link is not accepted. This application is applied to a WLAN system that supports a next generation Wi-Fi protocol of 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and other 802.11 series protocols; and for another example, a next generation protocol of 802.11be: Wi-Fi 8.Type: GrantFiled: June 15, 2023Date of Patent: April 9, 2024Assignee: Huawei Technologies Co., Ltd.Inventors: Yuchen Guo, Guogang Huang, Yunbo Li, Ming Gan

Patent number: 9247463Abstract: Systems and methods are described for providing non-mobile data channel access to a mobile application on a mobile computing device. A request for data may be received, by a client component on the mobile computing device, from the mobile application. The client component may automatically detect that mobile data is unavailable, and may automatically select a non-mobile data channel for the mobile application to communicate to an application server. The automatic selecting may be based on availability of a non-mobile data channel and bandwidth of the available non-mobile data channel. The client component may translate the request for data into a format of the selected non-mobile data channel and transmit the translated request for data to a back-end server via the selected non-mobile data channel.Type: GrantFiled: June 3, 2015Date of Patent: January 26, 2016Assignee: LOTUSFLARE, INC.Inventors: Qing Guo, Guogang Li, Shao Yong Xia

Patent number: 8483323Abstract: Methods for channel estimation for OFDM schemes are provided to combat multipath fading. Scattered pilot symbols are adaptively tracked by applying a weighted summation function over the received symbols to get a “snapshot” of the pilot symbols. Channel impulse response and frequency response can then be applied to the snapshot for channel estimation. The channel estimation is then used for interpolating one or more data symbols. Furthermore, the path information of the channel impulse response can help to optimize the OFDM window position.Type: GrantFiled: September 11, 2009Date of Patent: July 9, 2013Assignee: Amlogic Co., Ltd.Inventors: Guogang Li, Xiangyang Gong, Cindy C.
