Disclosed is a technology for avoiding a decrease in throughput due to duplicate transmission of downlink packets when a split bearer is deleted. One characteristic of the present invention pertains to user equipment having a transmission/reception unit that communicates simultaneously with a master base station and a secondary base station by means of dual connectivity, a radio link control (RLC) layer processing unit having a RLC layer for the master base station and a RLC layer for the secondary base station, and a packet data convergence protocol (PDCP) layer processing unit having a PDCP layer that transmits and receives data between the RLC layer for the master base station and the RLC layer for the secondary base station. When a split bearer that has been set for the secondary base station is deleted, the RLC layer processing unit executes a re-establishment process with respect to the RLC layer for the secondary base station, and releases the split bearer after the re-establishment process has been executed. |
