Abstract: A communication method, apparatus, and system are provided. The method may include: A terminal apparatus determines first indication information, where the first indication information indicates a status of a multicast/broadcast service, and the status of the multicast/broadcast service includes an inactive state; and the terminal apparatus stops, based on the first indication information, using a first radio network temporary identifier to monitor a physical downlink control channel corresponding to a multicast broadcast traffic channel. In the method, a network apparatus indicates the status of the multicast/broadcast service to the terminal apparatus. When determining that the status of the multicast/broadcast service is inactive, the terminal apparatus may not monitor the physical downlink control channel corresponding to the multicast broadcast traffic channel. This reduces power consumption of the terminal apparatus.

Abstract: A terminal device camps on a first cell in an idle state or an inactive state. The terminal device measures the first cell based on a first non-cell defining synchronization signal/physical broadcast channel block (NCD-SSB) frequency, and measures a second cell based on the first NCD-SSB frequency and/or a cell defining synchronization signal/physical broadcast channel block (CD-SSB) frequency. The terminal device performs cell reselection based on a measurement result of the first cell and a measurement result of the second cell.

Abstract: The method is used to page, by using a paging message, a terminal device that joins a multicast service, so that the terminal device attempts to enter an RRC connected state to receive data of the multicast service. In this application, the terminal device receives a first paging message, and initiates radio resource control RRC connection resume when a first condition is met. The first condition includes: The first paging message includes an identifier of a first multicast service and does not include an identifier of the terminal device; or the first paging message includes the identifier of the first multicast service and a first identifier of the terminal device, where the first identifier is associated with RAN paging.

Abstract: This application discloses a communication method and a communication apparatus. The method includes: A terminal device receives wake-up information from a network device, and switches from a first state to a second state in response to the wake-up information. The wake-up information includes one or more of the following information: a first cell bar indication, a second cell bar indication, a resource configuration change indication, a resource configuration, and cell identification information. The first cell bar indication indicates whether a terminal device is allowed to select or reselect a cell. This application provides a new energy saving method. Before receiving the wake-up information, the terminal device does not perform other communication, to reduce energy consumption. In addition, the wake-up information may include cell bar indication information, so that the terminal device can select a suitable cell after the terminal device is waken up, and therefore communication efficiency is improved.

Abstract: Data transmission methods and apparatuses, relate to the field of communications technologies are described. In an example method, a distributed unit (DU) receives a first packet data convergence protocol (PDCP) packet data unit (PDU) from a central unit (CU), where the first PDCP PDU carries data of a multicast broadcast service (MBS). The DU sends the first PDCP PDU to at least two terminal devices. The DU sends a status report to the CU, where the status report indicates results of sending the first PDCP PDU to the at least two terminal devices.
