Abstract: A data transmission control method, apparatus and system are provided. A radio communication node receives a data packet sent by a base station, where the data packet is generated by using a Packet Data Convergence Protocol protocol data unit (PDCP PDU) of the base station. The radio communication node acquires the PDCP PDU, which is used as a Radio Link Control service data unit (RLC SDU), in the data packet. The radio communication node sends data generated by using the RLC SDU to a user equipment, where a user plane connection is established between the radio communication node and the user equipment, and a control plane connection is established between the base station and the user equipment.

Abstract: A method and a system for implementing time division duplex configuration of a secondary serving cell are provided. A primary base station receives time division duplex TDD configuration information of a secondary serving cell and an identity of the secondary serving cell from a secondary base station, where the TDD configuration information of the secondary serving cell is allocated by the secondary base station to the secondary serving cell. The primary base station sends the TDD configuration information of the secondary serving cell and the identity of the secondary serving cell to a terminal, so that the terminal determines an uplink-downlink subframe allocation of the secondary serving cell according to the TDD configuration information.
