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.
