A multicast transmission method, comprising: receiving, by a user equipment, multicast resource information sent by a base station of a first cell, wherein the multicast resource information is used to indicate a resource configuration used by at least one second cell to transmit multicast service data, wherein the multicast resource information comprises time domain offset information, and the time domain offset information is used to indicate a time offset between the first cell and each second cell, wherein the multicast resource information further comprises service type information of the multicast service data; and the user equipment, based on the service type information, whether to receive the multicast service data by using the resource configuration in the multicast resource information, wherein that the user equipment determines, based on the service type information, whether to receive the multicast service data by using the resource configuration in the multicast resource information comprises: determining, by the user equipment based on the service type information, whether a priority of the multicast service data is higher than a priority of unicast service data transmitted by the base station of the first cell to the user equipment; and if the priority of the multicast service data is higher than the priority of the unicast service data transmitted by the base station of the first cell to the user equipment, receiving, by the user equipment, the multicast service data based on the resource configuration, and when receiving the multicast service data, skipping responding to scheduling signaling of the unicast service data from the base station of the first cell. receiving, by a user equipment, multicast resource information sent by a base station of a first cell, wherein the multicast resource information is used to indicate a resource configuration used by at least one second cell to transmit multicast service data, wherein the multicast resource information comprises time domain offset information, and the time domain offset information is used to indicate a time offset between the first cell and each second cell, wherein the multicast resource information further comprises service type information of the multicast service data; and the user equipment, based on the service type information, whether to receive the multicast service data by using the resource configuration in the multicast resource information, wherein that the user equipment determines, based on the service type information, whether to receive the multicast service data by using the resource configuration in the multicast resource information comprises: determining, by the user equipment based on the service type information, whether a priority of the multicast service data is higher than a priority of unicast service data transmitted by the base station of the first cell to the user equipment; and if the priority of the multicast service data is higher than the priority of the unicast service data transmitted by the base station of the first cell to the user equipment, receiving, by the user equipment, the multicast service data based on the resource configuration, and when receiving the multicast service data, skipping responding to scheduling signaling of the unicast service data from the base station of the first cell. determining, by the user equipment based on the service type information, whether a priority of the multicast service data is higher than a priority of unicast service data transmitted by the base station of the first cell to the user equipment; and if the priority of the multicast service data is higher than the priority of the unicast service data transmitted by the base station of the first cell to the user equipment, receiving, by the user equipment, the multicast service data based on the resource configuration, and when receiving the multicast service data, skipping responding to scheduling signaling of the unicast service data from the base station of the first cell.
