Disclosed in embodiments of the present application are a communication processing method and apparatus in the tight coupling between long-term evolution and 5G. The method comprises: in the communication in the tight coupling between long-term evolution and 5G, after a base station side determines that a terminal is in the coverage of a 5G network, requesting measurement configurations of the 5G network from a node of the 5G network; after the measurement configurations sent by the node in the 5G network are received, forwarding the measurement configuration to the terminal; receiving, on the terminal side, the measurement configurations sent by the node of the 5G network and forwarded by the LTE base station side; performing signal processing according to the measurement configurations; receiving, on the node of the 5G network, the 5G network measurement configuration request sent by the LTE base station side; sending the measurement configurations to the LTE base station side; and performing signal processing according to the measurement configurations. By using the present application, the 5G measurement is executed more specifically, related signaling overheads can be reduced, and accordingly a solution in which the network side determines whether a 5G secondary base station and a carrier need to be added.
