Abstract: This application provides for a data transmission method, an apparatus, and a device. The method may be applied to a relay communication system. The method includes a first network device that receives a first data packet. The first data packet is a data packet of a first multimedia broadcast multicast service (MBMS), and the first data packet carries first information. When second information of the first network device matches the first information, the first network device sends the first data packet to a terminal device that accesses the first network device. The second information is preconfigured for the first network device. In this way, the MBMS is transmitted in the relay communication system.

Abstract: A communication method includes obtaining, by a terminal device or a chip in the terminal device, configuration information of a multicast service. The configuration information is useable by the terminal device to receive data of the multicast service. The method further includes receiving first indication information from an access network device. The first indication information is useable to indicate a manner of obtaining configuration update information of the multicast service by the terminal device. The manner of obtaining the configuration update information of the multicast service is a first manner or a second manner. The first manner is obtaining the configuration update information by receiving a common message. The second manner is obtaining the configuration update information by receiving a dedicated message.

Abstract: This application provides a paging message detection method and apparatus, and a communication device. A first access device determines a first resource when the first access device is to send a radio access network paging message to a first terminal device in an inactive state, where the first resource is to carry a first wake-up signal; and the first wake-up signal is to indicate the first terminal device to detect downlink control information for scheduling the paging message that is carried by a first paging occasion resource. The first access device sends the first wake-up signal to the first terminal device on the first resource. The first access device sends, on the first paging occasion resource, the downlink control information for scheduling the paging message. In this way, power consumption of the terminal device can be reduced, and electric energy can be saved.
