TERMINAL DEVICE, BASE STATION DEVICE, METHOD, AND INTEGRATED CIRCUIT
A terminal apparatus includes a receiver configured to receive a first message and a controller configured to perform a measurement based on a measurement configuration included in the first message. The measurement configuration is associated with a secondary cell group. The controller releases the measurement configuration based on a release of Multi Radio access technology (RAT)-Dual Connectivity (MR-DC).
1 . A terminal apparatus comprising:
a receiver configured to receive a first message; and
a controller configured to perform a measurement based on a measurement configuration included in the first message, the measurement configuration being associated with a secondary cell group,
wherein the controller releases the measurement configuration based on a release of Multi Radio access technology (RAT)-Dual Connectivity (MR-DC).
2 . The terminal apparatus according to claim 1 , wherein
the controller releases the MR-DC in a case that the MR-DC is configured based on at least one of re-establishment of a radio resource control (RRC) connection and resumption of an RRC connection.
3 . A base station apparatus comprising:
a processing unit configured to notify a terminal apparatus, for which a secondary cell group of new radio (NR) is configured in Multi Radio access technology (RAT)-Dual Connectivity (MR-DC), of a release of the MR-DC,
wherein notification of the release of the MR-DC causes the terminal apparatus to release a measurement configuration associated with the secondary cell group.
4 . A method applied to a terminal apparatus, the method comprising:
receiving a first message;
performing a measurement based on a measurement configuration included in the first message, the measurement configuration being associated with a secondary cell group; and
releasing the measurement configuration based on a release of Multi Radio access technology (RAT)-Dual Connectivity (MR-DC).
5 . The method according to claim 4 , the method further comprising:
releasing MR-DC in a case that MR-DC is configured based on at least one of re-establishment of a radio resource control (RRC) connection and resumption of an RRC connection.
6 . A method applied to a base station apparatus, the method comprising:
notifying a terminal apparatus, for which a secondary cell group of new radio (NR) is configured in Multi Radio access technology (RAT)-Dual Connectivity (MR-DC), of a release of the MR-DC,
wherein notification of the release of the MR-DC causes the terminal apparatus to release a measurement configuration associated with the secondary cell group.
7 . An integrated circuit mounted on a terminal apparatus, the integrated circuit causing the terminal apparatus to:
receive a first message;
perform a measurement based on a measurement configuration included in the first message, the measurement configuration being associated with a secondary cell group; and
release the measurement configuration based on a release of Multi Radio access technology (RAT)-Dual Connectivity (MR-DC).
8 . The integrated circuit according to claim 7 , wherein the integrated circuit further causes the terminal apparatus to:
release the MR-DC in a case that the MR-DC is configured based on at least one of re-establishment of a radio resource control (RRC) connection and resumption of an RRC connection.
9 . An integrated circuit mounted on a base station apparatus, the integrated circuit causing the base station apparatus to:
notify a terminal apparatus, for which a secondary cell group of new radio (NR) is configured in Multi Radio access technology (RAT)-Dual Connectivity (MR-DC), of a release of the MR-DC,
wherein notification of the release of the MR-DC causes the terminal apparatus to release a measurement configuration associated with the secondary cell group.
