Abstract
The present disclosure provides a time-and-frequency synchronization method, a network device, and a terminal. The time-and-frequency synchronization method for the terminal includes: subsequent to determining that the terminal in an idle state or a DRX state needs to be woken up to receive a downlink signal, receiving a physical signal for time-and-frequency synchronization from the network device; and performing time-and-frequency synchronization in accordance with the physical signal.
