Abstract

A user equipment is disclosed that includes a transmission and reception unit configured to communicate with a master base station and a secondary base station simultaneously in dual connectivity. The user equipment includes a Radio Link Control (RLC) layer processing unit configured to have an RLC layer for the master base station and an RLC layer for the secondary base station and a Packet Data Convergence Protocol (PDCP) layer processing unit configured to have a PDCP layer transmitting and receiving data to/from the RLC layer for the master base station and the RLC layer for the secondary base station. When a split bearer configured for the secondary base station is deleted, the RLC layer processing unit performs re-establishment on the RLC layer for the secondary base station and releases the split bearer after execution of the re-establishment.
