  • Patent number: 12375955
    Abstract: A method for indicating to skip PDCCH monitoring and an apparatus are provided, to indicate, by using downlink control information, a terminal device to skip PDCCH monitoring. After a network device sends DCI that includes PDCCH skipping indication information to the terminal device, the terminal device determines, based on the PDCCH skipping indication information, not to monitor a PDCCH in a first time interval. In this way, the DCI is used to indicate the terminal device to skip PDCCH monitoring, and specific signaling used to indicate to skip PDCCH monitoring is clarified, thereby saving energy of the terminal device.

  • Patent number: 12200580
    Abstract: A message transmission method is provided. User equipment may receive a power saving message from a network device, where the power saving message carries indication information of a short message, and the short message includes at least one of the following: a public warning system notification or system information modification information. Then, the user equipment obtains the short message from the power saving message. In this way, when the user equipment is in a connected state, the user equipment may obtain the short message by using the power saving message, for example, a PoSS, instead of by monitoring a paging PDCCH; and when the UE is in a sleep state, the UE is not woken up to monitor the paging PDCCH. This reduces power consumption of the user equipment in the connected state.
