Abstract: This application provides a multicast service implementation method and apparatus. The method includes: receiving, by a first network device, a first unicast join message sent by a second network device, where the first unicast join message is used to request to join a multicast group, a source address of the first unicast join message is an address of the second network device, and a destination address of the first unicast join message is a multicast source address or a rendezvous point (RP) address; and establishing, by the first network device, a tunnel from the first network device to the second network device based on the first unicast join message. The multicast service implementation method and apparatus in embodiments of this application help improve availability of a multicast service.

Abstract: A data transmission method, device, and system are disclosed. A specific solution includes: sending, by a base station, an NPSS to UE by using a first subframe in a first radio frame and a first subframe in a second radio frame, where the first radio frame and the second radio frame are consecutive, and both the first radio frame and the second radio frame use a TDD uplink-downlink subframe configuration; sending, by the base station, an NPBCH to the UE by using a second subframe in the first radio frame and a second subframe in the second radio frame; sending, by the base station, an NSSS to the UE by using a third subframe in the first radio frame; and sending, by the base station, a SIB1-NB to the UE by using a third subframe in the second radio frame.

Abstract: Embodiments of the present invention provide a resource scheduling method. In the method, a terminal device receives a downlink control information (DCI) indication sent by a network device, wherein the DCI is used to indicate a first resource, and the first resource is a time-frequency resource for narrowband physical uplink shared channel (NPUSCH) format 2 transmission, wherein the NPUSCH format 2 is used to bear downlink hybrid automatic repeat request-acknowledgment (HARQ-ACK) feedback information, determines the first resource according to the DCI, and sends a scheduling request to the network device on the first resource

Abstract: Method and system for setting up a bearer are disclosed. The bearer setup method includes these steps: a packet data network gateway (PGW) obtains first quality of service (QoS) information and a first bearer identifier (ID), and sets up a bearer between the PGW and a radio access network (RAN) according to the first QoS information, where the bearer is associated with the first bearer ID; the RAN sets up a radio bearer (RB) with a user equipment (UE) according to second QoS information associated with the first QoS information, where the RB is associated with a second bearer ID associated with the first bearer ID.

Abstract: This application provides a resource configuration method. The method includes: generating, by a network device, a first signal; and sending, by the network device, the first signal to a terminal device at a target resource location. The target resource location includes at least one subframe, and the at least one subframe is an invalid subframe. This implements that the network device sends the first signal in the invalid subframe. Based on a mechanism of the invalid subframe, a terminal device that does not need to receive the first signal may postpone the invalid subframe, and a terminal device that needs to receive the first signal may receive the first signal in the invalid subframe.
