Abstract
A method and apparatus for secondary base station change in a mobile communication system are provided. Method for secondary node change includes receiving conditional reconfiguration information from the base station, transmitting to the base station a first response message with an transaction identifier, performing evaluation based on the configuration generated by a second base station and transmitting a second response message with an identifier indicating which conditional reconfiguration is executed.
Claims15
A method by a terminal, the method comprising:
- receiving, by the terminal from a base station, a specific Long Term Evolution (LTE) downlink (DL) message;
- determining, by the terminal and based on the specific LTE DL message, that execution condition is associated with a measurement configuration of Secondary Cell Group (SCG);
- performing, by the terminal and based on the execution condition, conditional reconfiguration evaluation for a specific cell based on the measurement configuration of SCG;
- performing, by the terminal and based on a specific second New Radio (NR) DL message, conditional reconfiguration execution for the specific cell in case that execution condition is fulfilled;
- and
- transmitting, by the terminal to the base station, a LTE uplink (UL) message,
- wherein:
- the specific LTE DL message comprises a nr-SecondaryCellGroupConfig;
- the nr-SecondaryCellGroupConfig comprises a first NR DL message;
- the first NR DL message comprises one or more second NR DL messages;
- and
- each of the one or more second NR DL messages is associated with one or two measurement identifiers and a conditional reconfiguration identifier.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver configured to transmit and receive a signal;
- and
- a controller configured to control the transceiver to:
- receive from a base station a specific Long Term Evolution (LTE) downlink (DL) message,
- determine, based on the specific LTE DL message, that execution condition is associated with a measurement configuration of Secondary Cell Group (SCG),
- perform, based on the execution condition, conditional reconfiguration evaluation for a specific cell based on the measurement configuration of SCG,
- perform, based on a specific second New Radio (NR) DL message, conditional reconfiguration execution for the specific cell in case that execution condition is fulfilled, and
- transmit to the base station a LTE uplink (UL) message,
- wherein:
- the specific LTE DL message comprises a nr-SecondaryCellGroupConfig;
- the nr-SecondaryCellGroupConfig comprises a first NR DL message;
- the first NR DL message comprises one or more second NR DL messages;
- and
- each of the one or more second NR DL messages is associated with one or two measurement identifiers and a conditional reconfiguration identifier.
