Title:
RADIO TERMINAL, MASTER NODE, AND METHODS PERFORMED BY THESE
Document Type and Number:
Japanese Patent JP2022132516
Kind Code:
A
Abstract:
To enable a secondary node (SN) to know a condition for performing a conditional primary cell change for a primary cell of a secondary cell group is met, where RRC signaling between the secondary node and a radio terminal is performed via a master node (MN).SOLUTION: A radio terminal (3) receives a third RRC message of an MN Radio Access Technology (RAT) from an MN (1). The third RRC message contains a first RRC message of an SN RAT from an SN (2) that includes a condition for performing a conditional primary cell (PSCell) change of a secondary cell group from a first cell to a second cell. In response that the condition for performing the change included in the first RRC message is met, the radio terminal (3) transmits a fourth RRC message of the MN RAT containing a second RRC message of the SN RAT to the MN (1).SELECTED DRAWING: Figure 2
