Abstract
Methods and apparatuses are provided in a wireless communication system. A first message is transmitted, to a secondary base station, for querying a first secondary cell group (SCG) configuration associated with the secondary base station. A second message is received from the secondary base station after transmitting the first message. The first message includes information indicating that the master base station requests the first SCG configuration, and the second message includes information on the first SCG configuration.
Claims16
A method performed by a master base station in a wireless communication system, the method comprising:
- transmitting, to a secondary base station, a modification request message for querying a first secondary cell group (SCG) configuration associated with the secondary base station;
- and
- receiving, from the secondary base station, a modification response message, after transmitting the modification request message,
- wherein, in case that the modification request message includes information indicating that the master base station requests the first SCG configuration,
- the modification response message includes a container for a radio resource control (RRC) message including information on the first SCG configuration.
A method performed by a secondary base station in a wireless communication system, the method comprising:
- receiving, from a master base station, a modification request message for querying a secondary cell group (SCG) configuration associated with the secondary base station;
- and
- transmitting, to the master base station, a modification response message, after receiving the modification request message,
- wherein, in case that the modification request message includes information indicating that the master base station requests the SCG configuration,
- the modification response message includes a container for a radio resource control (RRC) message including information on the SCG configuration.
A master base station in a wireless communication system, the master base station comprising:
- a transceiver;
- and
- a controller coupled with the transceiver and configured to:
- transmit, to a secondary base station, a modification request message for querying a first secondary cell group (SCG) configuration associated with the secondary base station;
- and
- receive, from the secondary base station, a modification response message, after transmitting the modification request message,
- wherein, in case that, the modification request message includes information indicating that the master base station requests the first SCG configuration, and
- wherein the modification response message includes a container for a radio resource control (RRC) message including information on the first SCG configuration.
A secondary base station in a wireless communication system, the secondary base station comprising:
- a transceiver;
- and
- a controller coupled with the transceiver and configured to:
- receive, from a master base station, a modification request message for querying a secondary cell group (SCG) configuration associated with the secondary base station;
- and
- transmit, to the master base station, a modification response message, after receiving the modification request message,
- wherein, in case that the modification request message includes information indicating that the master base station requests the SCG configuration,
- the modification response message includes a radio resource control (RRC) message including information associated with the SCG configuration.
