State switching method and apparatus and beacon signal sending method and apparatus

A terminal, comprising a processor, a memory, and instructions stored in the memory and capable of running on the processor, wherein instructions, when executed by the processor, implement:

• in a case of monitoring for a wake-up signal in a low-power state, detecting a beacon signal based on pre-configured configuration information;
• and
• switching to a normal idle state in a case that a detection result is at least one of the following:
• the terminal has detected no beacon signal;
• or
• signal quality of the beacon signal detected by the terminal is lower than a preset threshold;
• wherein the instructions, when executed by the processor, further implement following step before the detecting the beacon signal based on pre-configured configuration information:
• in the normal idle state or a connected state, obtaining the configuration information;
• wherein the configuration information comprises at least one of the following:
• frequency of the beacon signal, subcarrier of the beacon signal, slot of the beacon signal, sequence of the beacon signal, period of the beacon signal, or power of the beacon signal.

A state switching method, comprising:

• obtaining, by a terminal in a normal idle state or a connected state from a network side device, a configuration information;
• wherein the configuration information comprises at least one of the following:
• frequency of a beacon signal, subcarrier of the beacon signal, slot of the beacon signal, sequence of the beacon signal, period of the beacon signal, or power of the beacon signal;
• switching, by the terminal, from the normal idle state or the connected state to a low-power state for monitoring a wake-up signal sent by the network side device without monitoring synchronization information, paging information, and/or system information broadcast (SIB) sent by the network side device;
• when monitoring for the wake-up signal in the low-power state, detecting, by the terminal, the beacon signal sent by the network side device based on the configuration information;
• and
• switching, by the terminal, from the low-power state to the normal idle state in a case that a detection result is at least one of the following:
• the terminal has detected no beacon signal;
• or
• signal quality of the beacon signal detected by the terminal is lower than a preset threshold.
