Terminal
A terminal 200 includes a receiving unit 220 that receives a plurality of pieces of configuration information of transition destination cells from a gNB 100 A by a conditional cell transition in the gNB 100 A in which the terminal 200 resides, and a control unit 250 that performs a transition to a transition destination cell based on configuration information of the transition destination cell, without receiving a transition command. When the receiving unit 220 receives modification information indicating whether there is a modification to the configuration information of the transition destination cell, the control unit 250 modifies the configuration information of the transition destination cell based on the modification information.
1 . A terminal comprising:
a receiver that receives, from a transition source cell, configuration information including information on a transition destination cell and a transition condition to the transition destination cell; and
a processor that performs a transition to the transition destination cell based on the configuration information, without receiving a transition command,
wherein the receiver receives, from the transition source cell, modification information to the configuration information, and
when the modification information indicates that there is an update to the information on the transition destination cell among the information on the transition destination cell and the transition condition to the transition destination cell included in the configuration information, the processor updates the information on the transition destination cell among the information on the transition destination cell and the transition condition to the transition destination cell included in the configuration information without updating the transition condition to the transition destination cell among the information on the transition destination cell and the transition condition to the transition destination cell included in the configuration information, based on the modification information.
2 . A radio communication system comprising:
a terminal and a radio base station forming a transition source cell,
wherein the terminal includes:
a receiver that receives, from the radio base station, configuration information including information on a transition destination cell and a transition condition to the transition destination cell; and
a processor that performs a transition to the transition destination cell based on the configuration information, without receiving a transition command,
wherein the receiver receives, from the radio base station, modification information to the configuration information, and
when the modification information indicates that there is an update to the information on the transition destination cell among the information on the transition destination cell and the transition condition to the transition destination cell included in the configuration information, the processor updates the information on the transition destination cell among the information on the transition destination cell and the transition condition to the transition destination cell included in the configuration information without updating the transition condition to the transition destination cell among the information on the transition destination cell and the transition condition to the transition destination cell included in the configuration information, based on the modification information.
3 . A radio communication method applied to a terminal, comprising:
receiving, from a transition source cell, by the terminal, configuration information including information on a transition destination cell and a transition condition to the transition destination cell;
receiving, from the transition source cell, by the terminal, modification information to the configuration information;
updating, by the terminal, the information on the transition destination cell among the information on the transition destination cell and the transition condition to the transition destination cell included in the configuration information without updating the transition condition to the transition destination cell among the information on the transition destination cell and the transition condition to the transition destination cell included in the configuration information, based on the modification information, when the modification information indicates that there is an update to the information on the transition destination cell among the information on the transition destination cell and the transition condition to the transition destination cell included in the configuration information; and
performing, by the terminal, a transition to the transition destination cell based on the configuration information, without receiving a transition command.
