Abstract: A communications method includes: when a terminal device is in a non-connected state, a system information block is received from a network device, where the system information block includes first information; and configuration of a reference signal used for operations such as automatic gain control (AGC) adjustment and time and frequency synchronization can be known based on the first information. In this way, the terminal device can wake up at a location of a first reference signal to prevent terminal device from waking up too early at a location of a synchronization signal block and to effectively reduce power consumption of the terminal device.
