Source and target node coordination for measurement configuration in pscell change

A method for a Primary Secondary Cell Group (SCG) Cell (PSCell) change procedure, the method comprising:

• sending, from a master node (MN) to a target secondary node (T-SN), a first message including configuration information based on which the T-SN determines whether to provide a full configuration or a delta configuration for measurement-related information for one or more candidate target PSCells acknowledged by the T-SN;
• receiving, at the MN from the T-SN in accordance with the configuration information, a second message including the full configuration or the delta configuration for measurement-related information for the one or more candidate target PSCells acknowledged by the T-SN.

A method for a Primary Secondary Cell Group (SCG) Cell (PSCell) change procedure, the method comprising:

• sending, from a master node (MN) to a target secondary node (T-SN), a first message including a request to provide configuration for one or more candidate target PSCells to be acknowledged by the T-SN, wherein the request determines for at least a first parameter of the configuration mandatory use of full configuration or optional use of delta configuration, and for at least a second parameter optional use of full or delta configuration;
• receiving, at the MN from the T-SN in accordance with the request, a second message including the full configuration or the delta configuration for parameters for the one or more candidate target PSCells acknowledged by the T-SN.
