The embodiment of the invention provides a cell switching method, a terminal, a base station, a device and a storage medium, and the method comprises the steps: carrying out the measurement of all cells based on a plurality of channel state information reference signal (CSI-RS) resource sets corresponding to a plurality of cells; and sending the measurement result of at least one cell in all the cells to the base station of the current cell, so that the base station of the current cell performs cell switching judgment based on the received measurement result of the at least one cell. According to the method, the terminal, the base station, the device and the storage medium provided by the embodiment of the invention, cell measurement can be carried out on the basis of the CSI-RS resource set only in a layer 1 without passing through a layer 3 or introducing an additional filter in the layer 3 for filtering operation, so that the time delay introduced by the additional filtering operation can be avoided, and the user experience is improved. And the complexity of the cell switching process is reduced, so that the data transmission quality of the terminal is improved, and the reliability of a data transmission link is ensured.
Description
technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a cell handover method, a terminal, a base station, a device, and a storage medium. Background technique [0002] In a mobile communication system, when a terminal in the communication state moves from one cell to another, or the link quality of the serving cell deteriorates, in order to ensure the continuity of communication, the network needs to handover the terminal to another cell. A cell continues to provide services for the terminal, that is, performs cell handover. [0003] At present, the cell handover of the NR (New RAT, new air interface) system has a large delay. For high-speed mobile terminals, the cell handover delay will reduce the quality of data transmission, resulting in the reliability of the link cannot be guaranteed. Contents of the invention [0004] Embodiments of the present application provide a cell switching method, a term...
