  • Publication number: 20230171654
    Abstract: The present disclosure provides a communication method and apparatus, the method includes: sending, by a first network device, a handover request to a second network device, where the handover request is used for handing over a target network device that serves a terminal device from the first network device to a second network device, and the handover request includes a TA of the terminal device with the second network device, or includes location information of the terminal device and a movement trajectory of the terminal device for determining the TA of the terminal device with the second network device. In this way, as the second network device after handover has determined the timing advance TA of the terminal device with the second network device, an uplink transmission time indicated by the network device can be prevented from being before a downlink reception time, ensuring usability of uplink resource configuration.

  • Publication number: 20230087088
    Abstract: A display may be formed by an array of light-emitting diodes mounted to the surface of a display substrate. The light-emitting diodes may be inorganic light-emitting diodes formed from separate crystalline semiconductor structures. An array of pixel control circuits may be used to control light emission from the light-emitting diodes. Each pixel control circuit may be configured to control one or more respective passive matrices. To control partial pixel cells in the display, a donor pixel control circuit in a partial pixel cell may control the pixels in a receptor partial pixel cell without a pixel control circuit. To mitigate the size of an inactive area of the display, fanout signal lines for the display may be formed in the light-emitting active area of the display. The fanout signal lines may be formed between a row of pixel control circuits and a bottom edge of the light-emitting active area.
