Abstract: Embodiments of the present application provide a cell access method, a device, and a storage medium. The method includes: a terminal device receives a first synchronization signal block SSB; the terminal device determines, according to a preset bandwidth and bandwidth information contained in the first SSB, a target cell that supports the access by the terminal device, and the terminal device accesses the target cell. If the cell corresponding to the first SSB is not the target cell, the terminal device does not need to blindly detect the PDCCH of the cell, which saves the time for accessing the network. Further, whether the cell corresponding to the first SSB is the target cell is determined only according to the bandwidth information contained in the first SSB and the preset bandwidth, without adding additional signaling overhead, which has little impact on the existing NR system, and the complexity is low.
