  • Publication number: 20240381277
    Abstract: Provided in the embodiments of the present disclosure are a TA-based synchronization method, and a device, an apparatus and a storage medium, wherein the method is applied to a terminal device. The method includes determining a second TA between a terminal device and a cell where a target beam, which performs data transceiving with the terminal device, is located; and applying the second TA, wherein the second TA is configured for synchronization between the terminal device and the cell where the target beam is located. The present disclosure aims to solve the problem, in the relevant art, of a time delay caused by the acquisition of a TA between a UE and a target cell by means of random access after the UE switches the data transmission thereof to the target cell, to improve the switching efficiency of a terminal device.

  • Publication number: 20240306101
    Abstract: The present disclosure relates to the field of communications. Disclosed are a synchronization state processing method, and a device and a storage medium. The method comprises: during the process of a terminal in an idle state or an inactive state transmitting an SRS to a base station for uplink positioning, the terminal or the base station acquires channel state information of a transmission channel between the terminal and the base station, and detecting, on the basis of the channel state information, a synchronization state between the terminal, which is performing idle-state or inactive-state uplink positioning, and the base station; and when uplink out-of-synchronization is detected, the terminal or the base station uses a corresponding processing approach to continue to guarantee the subsequent idle/inactive positioning process flow.

  • Publication number: 20240080659
    Abstract: The present application relates to the technical field of wireless communications, and discloses a terminal location capability reporting method and device. The method comprises: an access and mobility management function (AMF) entity obtains and stores a terminal location capability of a terminal, and after a location service for a target terminal arrives, if the terminal location capability of the target terminal is stored in the AMF entity, the AMF entity transmits the terminal location capability of the target terminal to a location management function (LMF) entity, so that the LMF sets a location method for the target terminal according to the terminal location capability. In the process above, when the LMF entity needs to obtain the terminal location capability of the target terminal, the terminal location capability of the target terminal can be directly obtained from the AMF entity, and there is no need to interact with the terminal to obtain the terminal location capability.

  • Patent number: 10290663
    Abstract: The invention provides a manufacturing method of a thin film transistor and a manufacturing method of an array substrate. A photoresist is used to define a to-be-doped region of an amorphous silicon layer to thereby make a crystallization be occurred in a source contact region and a drain contact region. A crystallization direction is from the source contact region and the drain contact region towards a channel region, so that it can realize directional crystallization as far as possible, and therefore can improve crystallization efficiency and crystallization uniformity, reduce an influence of grain boundary applied to electron mobility and leakage current of the TFT and improve electrical characteristics of the TFT.
