Abstract: A terminal device receives a reference signal from a first cell, where time domain resources occupied by the reference signal are fewer than total time domain resources occupied by a synchronization signal block (SSB) of the first cell and system information (SI) of the first cell. The terminal device sends a wake-up signal (WUS) to the first cell, where the wake-up signal is used to wake up the first cell to send the SSB and/or the SI. In this way, the terminal device can quickly access the cell, to reduce a delay of accessing the cell by the terminal device, and improve communication performance. The time domain resources occupied by the reference signal are fewer than the total time domain resources occupied by the SSB of the first cell and the SI of the first cell.
