Description

(Cross-reference of related applications) This application claims priority to Chinese Patent Application No. 202110206796.6, filed in China on 22 February 2021, and all contents of that application are incorporated herein by reference. This application belongs to the field of communications technology, and specifically relates to a method and apparatus for switching states, and a method and apparatus for transmitting beacon signals. To meet the demand for power saving, terminals employ simplified circuits to receive wake-up signals at low power, resulting in a certain loss in wake-up signal detection sensitivity. For example, while the detection sensitivity for wake-up signals in the idle (IDLE) state is approximately -100 dBm, the sensitivity for detecting wake-up signals using the low-power method is -70 dBm to -90 dBm. However, during the process of detecting wake-up signals in the low-power state, movement or environmental changes can cause the terminal to move outside the coverage range of the low-power wake-up signal, making it impossible to receive the wake-up signal transmitted from the network side.
