TERMINAL DEVICE, BASE STATION DEVICE, AND METHOD

Title:

TERMINAL DEVICE, BASE STATION DEVICE, AND METHOD

Document Type and Number:

WIPO Patent Application WO/2019/098143

Kind Code:

A1

Abstract:

Provided is a feature pertaining to a terminal device, a method, and an integrated circuit with which it is possible to reduce the complexity of a protocol process and perform communication efficiently. A terminal device for performing communication with one or a plurality of base station devices, the terminal device having: a reception unit for receiving an RRC connection resetting message that includes a DRB setting from the base station devices; and a processing unit that, when information indicating that full setting will be applied is included in the RRC connection resetting message received by the reception unit and a DRB identifier included in the DRB settings information is not a part of the current settings of the terminal device and when an LTE PDCP entity is established in an established DRB having the DRB identifier, associates the established DRB with an EPS bearer identifier included in the DRB settings information.
