Abstract: This application provides a transmission method and device. The method includes: receiving, by a first device, a first RRC message sent by a second device, where the first RRC message includes first data and identification information, and then sending, by the first device, the first data and the identification information to a donor eNB of the first device by using a second RRC message. Because the first device and the second device send data by using an RRC message, network functions of the first device and the second device are simplified, and data transmission efficiency is increased after a plurality of relay nodes access an NB-IoT network.

Abstract: Embodiments can provide a transmission method and a wireless communications device. For achieving such, a multicast coverage level of a multicast service can be determined by a group communication application server. The multicast coverage level may be a coverage level used when a network device corresponding to the cell transmits the service in multicast mode. A multicast transmission indicator can be sent, by the group communication application server, to a network device of the multicast service through a BM-SC, an MME, and an MCE. The multicast coverage level indication information may correspond to the multicast coverage level. According to the method and the wireless communications device provided, a network element in a core network may determine a multicast coverage level based on a coverage level of a subscription terminal
