User equipment

Abstract

Techniques are disclosed for avoiding reduction in throughput due to redundant transmission of downlink packets when a split bearer is deleted. A user equipment includes a transmission and reception unit to communicate with a master base station and a secondary base station simultaneously in dual connectivity; an RLC (Radio Link Control) 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 PDCP (Packet Data Convergence Protocol) 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 the 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.
