Title:
TERMINAL DEVICE, BASE STATION DEVICE, COMMUNICATION SYSTEM, COMMUNICATION CONTROL METHOD, AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2015/115268
Kind Code:
A1
Abstract:
Provided are a terminal device, a base station device, a communication system, a communication control method, and an integrated circuit that achieve efficient control of communications where multiple cells are used. In communications that use a first radio link control (RLC) corresponding to a first cell group including at least a primary cell, a second radio link control (RLC) corresponding to a second cell group excluding the primary cell, and one packet data convergence protocol (PDCP) that belongs to the first cell group and processes data exchanged with the first RLC and the second RLC, a terminal device releases the second RLC on the basis of a list received from a base station device and containing an identifier of a data radio bearer associated with the second RLC.
