DATA TRANSMISSION METHOD AND DEVICE

摘要

The embodiments of the present invention provide a method and device for sending data. A second network equipment receives user data sent by a first network equipment through a first interface. The second network equipment receives control signaling sent by the first network equipment through a second interface, wherein the second interface is an air interface. The second network equipment sends the user data to a user equipment according to the control signaling. In the embodiments of the present invention, the first network equipment can send the control signaling to the UE and the second network equipment through the air interface, and does not send the control signaling and data signaling to the second network equipment through the same X2 interface, so that the first interface with longer transmission delay is prevented from being used for sending the control signaling, and the transmission delay of the control signaling between the network equipments is shortened.
