It should be noted that in the first operation mode, the mobile terminal will try to monitor the wake-up message at the beginning of each time period, if the wake-up message is received, the mobile terminal will continue to monitor the PDCCH messages that may be sent after the time period, and if the wake-up message is not received (whether the base station does not send the wake-up message to cause no reception or does not receive due to poor link conditions), the mobile terminal will not monitor the information transmission after the time period, which has the advantage that the base station does not repeatedly send the wake-up message.

The common problem of the two modes is that the mobile terminal cannot know what the specific reason for not receiving the wake-up message or the sleep message is (because the base station does not transmit or because the terminal cannot correctly receive), because the mobile terminal does not know whether the base station will necessarily transmit a certain message at the beginning of each time period, and if the link condition is poor, the mobile terminal cannot know the link condition is poor for a long time.
