| 摘要 |
Embodiments of the present invention provide a data transmission control method, apparatus and system, which relate to the communications field, can ensure inter-layer interaction between a Packet Data Convergence Protocol layer and a Radio Link Control layer of different apparatuses, and further satisfy data transmission requirements, so as to improve a throughput of a UE. The method includes: receiving, by a radio communication node, 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; acquiring, by the radio communication node, the PDCP PDU, which is used as a Radio Link Control service data unit RLC SDU, in the data packet; and sending, by the radio communication node, 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. The embodiments of the present invention are applied to data transmission between a base station and a user equipment. |
