Publication number: 20240073927Abstract: This application provides a data transmission method. The method includes: receiving a first PDCCH, where the first PDCCH includes first DCI, the first DCI indicates a first resource, and the first resource is used to carry first uplink data; determining a first time period or a second time period, where the first time period includes a time period for monitoring a second PDCCH, and the second time period does not include the second PDCCH; and monitoring the second PDCCH based on the first time period or the second time period.Type: ApplicationFiled: November 9, 2023Publication date: February 29, 2024Inventors: Ying Chen, Ruonan Yang, Yinggang Du, Jun Wang, Yunfei Qiao

Publication number: 20240031012Abstract: A wireless communication includes determining, by a satellite, at least one first signal, sending the at least one first signal to a terminal based on at least one first beam, and receiving a random access request from the terminal. Each first signal of the at least one first signal corresponds to one first beam of the at least one first beam. Each first signal of the at least one first signal includes information about a first geographical location of a center point of the one first beam of the at least one first beam corresponding to each first signal of the at least one first signal. The information about the first geographical location is useable to determine a second beam from the at least one first beam. The random access request includes an identifier of the second beam.Type: ApplicationFiled: September 27, 2023Publication date: January 25, 2024Inventors: Ruonan YANG, Ying CHEN, Rong LI, Jun WANG, Yinggang DU, Yu WANG, Yunfei QIAO

Publication number: 20230258479Abstract: An electronic device is described. The electronic device may include a housing, a rotatable crown, and a self-mixing interferometry (SMI) sensor positioned within the housing. The rotatable crown may include an array of retroreflective surface features that reflect incident light back to a light source. Each retroreflective surface feature of the array of retroreflective surface features may be formed as a corner-cube with three perpendicular faces. The SMI sensor or associated processing electronics may compare originally emitted light with reflected light to identify a movement or distance of the rotatable crown with respect to the SMI sensor.Type: ApplicationFiled: May 1, 2023Publication date: August 17, 2023Inventors: Xin Li, Damon R. Lemmon, David D. Dashevsky, Dianbo Guo, Peng Zhao, Ruonan Yang

Patent number: 11487859Abstract: Configurations for display stacks of an electronic device and methods for mitigating crosstalk are disclosed. The display stack may include a transceiver module, which may be located under or behind the display. The transceiver module may include a transmitter module, which may provide polarized light from the transmitter that may suppress module crosstalk. The transceiver module also may include a receiver module, which may include polarization control elements and an analyzer for differentiating between a target signal and a crosstalk signal. The polarization control on both the transmitter module and receiver module sides may suppress the crosstalk signals, which may be due to the reflections between and within the elements of the display stack and resulting from positioning the transceiver module behind the display.Type: GrantFiled: July 31, 2020Date of Patent: November 1, 2022Assignee: Apple Inc.Inventors: Tong Chen, Mark T. Winkler, Ruonan Yang, Tsu-Hui Lin, Wenrui Cai, Xiao Xiang

Patent number: 11238598Abstract: A head mounted display comprises an eye tracking system configured to enable eye tracking using polarization. The eye tracking system includes one or more illumination sources and an optical detector comprising polarization sensitive pixels. The one or more illumination sources are configured to illuminate a user's eye and generate reflections directed towards the optical detector. The eye tracking system determines, for each polarization sensitive pixel in a subset of the polarization sensitive pixels, one or more estimation parameters. The eye tracking system determines, for the subset of the polarization sensitive pixels, depth information for one or more glints associated with one or more surfaces of the eye, based in part on the polarization of the reflections and the one or more estimation parameters. The determined depth information is used to update a model of the eye. The eye tracking system determines eye tracking information based on the updated model.Type: GrantFiled: May 12, 2020Date of Patent: February 1, 2022Assignee: Facebook Technologies, LLCInventors: Michael Hall, Ruonan Yang
