Abstract

A terminal apparatus for communicating with one or more base station apparatuses, the terminal apparatus including: a receiver configured to receive an RRC connection reconfiguration message including a DRB configuration from the one or more base station apparatuses; and a processing unit configured to release a PDCP entity, in a case that information indicating that a full configuration is applied is included in the RRC connection reconfiguration message, and that a value of an EPS bearer identity included in the DRB configuration is part of a current configuration of the terminal apparatus, and that the PDCP entity is configured on a DRB corresponding to the EPS bearer identity.

Claims (12)

1. A terminal apparatus for communicating with one or more base station apparatuses, the terminal apparatus comprising:

a receiver configured to receive a Radio Resource Control (RRC) connection reconfiguration message including a Data Radio Bearer (DRB) configuration from the one or more base station apparatuses; and

a processor configured to release a Packet Data Convergence Protocol (PDCP) entity in a case that

information indicating that a full configuration is applied is included in the RRC connection reconfiguration message,

a value of an Evolved Packet System (EPS) bearer identity included in the DRB configuration is part of a current configuration of the terminal apparatus, and

the PDCP entity is configured on a DRB corresponding to the EPS bearer identity.

2. A method for a terminal apparatus for communicating with one or more base station apparatuses, the method comprising:

receiving a Radio Resource Control (RRC) connection reconfiguration message including a Data Radio Bearer (DRB) configuration from the one or more base station apparatuses; and

releasing a Packet Data Convergence Protocol (PDCP) entity in a case that

information indicating that a full configuration is applied is included in the RRC connection reconfiguration message,

a value of an Evolved Packet System (EPS) bearer identity included in the DRB configuration is part of a current configuration of the terminal apparatus, and

the PDCP entity is configured on a DRB corresponding to the EPS bearer identity.
