Patent number: 11881890Abstract: An electrical layer subnetwork connection protection includes determining, by a network device including a processor, signal status information based on a power of an obtained optical signal. The signal status information is used to indicate a state of a subnetwork connection carrying the optical signal. The method also includes filtering, by the network device, the signal status information based on a preset first threshold. The first threshold indicates a minimum duration in which the optical signal is in a valid state. The method further includes determining, by the network device based on the filtered signal status information, whether to switch a currently used first clock to a second clock different from the clock. The first clock or the second clock is used to initialize connection monitoring information in response to the determination of whether to switch the currently used first clock to the second clock.Type: GrantFiled: June 27, 2022Date of Patent: January 23, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Jun Yan, Guang Xie

Patent number: 11690109Abstract: The technology relates to establishing wireless communication links, or connections, between a first audio accessory device, a second audio accessory device, and a client computing device. After receiving signals from the client computing device to initiate audio output, the first audio accessory device and the second audio accessory device may both perform a series of steps in parallel to establish connections with the client computing device and with each other. The series of steps may include relaying one or more acknowledgement (ACK) signals between the audio accessory devices in order to confirm proper receipt of the signals from the client computing device at both audio accessory devices. Alternatively, the series of steps may include transmitting a jamming signal from one of the audio accessory devices in order to prevent an ACK signal from the other audio accessory device from reaching the client computing device and initiating audio output.Type: GrantFiled: June 8, 2021Date of Patent: June 27, 2023Assignee: Google LLCInventors: Hongyang Deng, Shijing Xian, Guang Xie, Chi Kin Benjamin Leung

Patent number: 11272571Abstract: The present disclosure provides for role switch with perceptible continuity of audio streaming during the role switch. The role switch occurs in two stages, with a first stage including a host link role switch and a second stage including a relay link role switch. For example, the host link role switch concerns the relationship of each audio receiver device to the host device, where the master device receives audio directly from the host for relay to the slave. The relay link role switch concerns a relationship between the audio receiver devices. For example, the communication master controls timing, such as when to send packets between the master and slave devices. Each stage of the two stage procedure may take approximately 100 ms or less. Between each stage, the audio buffers of the master and slave devices have an opportunity to refill.Type: GrantFiled: February 28, 2020Date of Patent: March 8, 2022Assignee: Google LLCInventors: Shijing Xian, Guang Xie, Jeffrey Kuramoto

Patent number: 9531483Abstract: UEs are adapted to facilitate calculation of signal-to-interference ratio (SIR) estimates in closed-loop transmission diversity (CLTD) communications before downlink and uplink synchronization is achieved. A UE may receive a transmission sent using transmission diversity. According to one example, the UE may calculate a plurality of signal-to-interference ratio (SIR) estimates for the received transmission, where each signal-to-interference ratio estimate is calculated using a different weight factor. The UE may further select one of the calculated signal-to-interference ratio (SIR) estimates to be employed for the received transmission. According to another example, the UE may calculate a signal-to-interference ratio (SIR) estimate for the received transmission without employing any weight factor. Other aspects, embodiments, and features are also included.Type: GrantFiled: December 9, 2013Date of Patent: December 27, 2016Assignee: QUALCOMM IncorporatedInventors: Wei Zhang, Guang Xie, Nate Chizgi, Prashant Udupa Sripathi, Todd Nicholas Tsakiris
