| 摘要 |
The present invention provides a method of controlling a radio link control (RLC) layer in a network system supporting dual connectivity of a UE with respect to a master eNB and a secondary eNB. In the method, the master eNB transmits a first RLC PDU processed by an RLC layer of the master eNB to the UE, the secondary eNB transmits a second RLC PDU processed by an RLC layer of the secondary eNB to the UE, and at least one of first RLC sorting information, which indicates that the first RLC PDU is processed by the RLC layer of the master eNB, and second RLC sorting information, which indicates that the second RLC PDU is processed by the RLC layer of the secondary eNB, is further transmitted to the UE. |
