determining the to-be-monitored wake up signal in the plurality of wake up signals based on the first category and the mapping relationship between category information and a wake up signal. In this way, a wake up signal corresponding to the first category may be searched for based on the first category and the mapping relationship between category information and a wake up signal, so as to determine the to-be-monitored wake up signal, where the wake up signal corresponding to the first category is the to-be-monitored wake up signal that the terminal device needs to monitor.

In a possible implementation, the determining a to-be-monitored wake up signal in the plurality of wake up signals based on the first category may include:

determining the to-be-monitored wake up signal in the plurality of wake up signals based on the first category and a grouping factor. In this way, the to-be-monitored wake up signal may be determined based on both the first category and the grouping factor.

In a possible implementation, the determining the to-be-monitored wake up signal in the plurality of wake up signals based on the first category and a grouping factor may include:

determining a plurality of to-be-determined wake up signals in the plurality of wake up signals based on the first category; and

determining the to-be-monitored wake up signal in the plurality of to-be-determined wake up signals based on the grouping factor.

In a possible implementation, the determining the to-be-monitored wake up signal in the plurality of wake up signals based on the first category and a grouping factor may include:

determining a plurality of to-be-determined wake up signals in the plurality of wake up signals based on the grouping factor; and
