Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular to a method, device, and readable storage medium for monitoring a wake-up signal. Background Art

[0002] In wireless communication technology, for example, in the fifth generation mobile communication technology (5G), in order to save power consumption of user equipment (UE), a main transceiver of the user equipment can be put into a sleep state.

[0003] The network device can send a wake-up signal (WUS), which can indicate to one or more UEs whether to wake up for downlink monitoring. For example, WUS includes 16 bits, corresponding to 16 UEs, and each bit corresponds to one UE. When the bit corresponding to a UE is 1, it indicates wake-up, and the UE turns on the main transceiver to receive downlink signals; when the bit corresponding to the UE is 0, it indicates not to wake up, and the UE keeps the main transceiver in the sleep state.

[0004] However, if the wake-up signal does not have a grouping function, or the grouping granularity is not fine enough, a WUS signal will wake up a large number of UEs, most of which will be false alarms, wasting the energy consumption of the UEs that are falsely alarmed. Summary of the invention
