| 摘要 |
The invention relates to a method of carrier aggregation-based separation of a control plane from a user plane, wherein base stations include a macro base station and a pico base station configured respectively to set up communication connections with a user equipment, and the method includes: configuring the macro base station and the pico base station respectively as a primary service cell and a secondary service cell; prioritizing controlling signaling over first MAC CE signaling to be transmitted over a scheduling grant on the macro base station; c. in the previous step, if the remaining scheduling grant on the macro base station after the control signaling is transmitted is available to the first MAC CE signaling, then the macro base station transmitting the first MAC CE signaling; otherwise, the macro base station transmitting the first MAC signaling to the pico base station; and prioritizing the first MAC CE control signaling over data part to be transmitted over a scheduling grant on the pico base station. The inventive method can optimize configuration of the scheduling grant on the macro base station while ensuring high mobility management. |
