Abstract: A multicast transmission method is disclosed. A base station of a first cell obtains first multicast resource information of at least one second cell, where the base station of the first cell is different from a base station of each second cell; and the base station of the first cell sends second multicast resource information to user equipment, where the second multicast resource information is used to indicate a resource configuration used by each second cell to transmit multicast service data. The base station of the first cell actively sends obtained multicast resource information to the user equipment in a broadcast manner. In this way, the base station of the first cell does not need to configure, in a unicast manner for each user equipment, a resource location for sending/reading the multicast service data of each second cell, thereby reducing signaling overheads.

Abstract: Embodiments of the present invention provide a data transmission method and apparatus, and relate to the communications field. The method includes: obtaining configuration information; establishing at least one logical channel according to an identifier of each logical channel and the corresponding transmission mode indication; obtaining a transmission resource according to the transmission mode indication of a logical channel to which device-to-device (D2D) buffered data belongs; and sending the D2D buffered data by using the obtained transmission resource. A problem that a resource allocation mode used by a terminal during D2D communication is relatively single and is not flexible enough is resolved, and the terminal can use different resource allocation modes according to a logical channel granularity, so that not only consumption of signaling resources of a network device can be reduced, but also QoS requirements of some services that require relatively high QoS can be satisfied.

Abstract: A scheduling request triggering method, apparatus, and system are disclosed. The method includes: obtaining, by a terminal device, an uplink semi-persistent scheduling resource allocated by a base station, where the uplink semi-persistent scheduling resource is used to transmit to-be-transmitted data on a logical channel of the terminal device; receiving, by the terminal device, scheduling request masking set by the base station for a first logical channel; and after determining that a triggering condition is satisfied, triggering, by the terminal device, a scheduling request via the first logical channel. In this way, when a status of data of the terminal device changes, an appropriate scheduling resource can be obtained, so as to ensure timely data transmission.
