Secondary cell group activation state configuration in multiple secondary cell group configurations

A user equipment (UE) for wireless communication, comprising:

• at least one processor;
• a transceiver communicatively coupled to the at least one processor;
• and
• a memory communicatively coupled to the at least one processor,
• wherein the at least one processor is configured to:
• operate in a multi-radio dual connectivity (MR-DC) mode with connections established to a source master node and a source secondary node;
• evaluate one or more link qualities between the UE and one or more target primary secondary cell group (SCG) cells (PSCells) respectively associated with one or more target secondary nodes;
• select a target PSCell from the one or more target PSCells based on the one or more link qualities and one or more execution conditions respectively associated with the one or more target PSCells of the one or more target secondary nodes;
• initiate a conditional execution procedure to connect to a target secondary node corresponding to the selected target PSCell;
• and
• responsive to a source SCG state corresponding to a source PSCell of the source secondary node being a deactivated state, perform either of:
• (a) changing an SCG state at the UE to an activated state and performing a random access channel (RACH) procedure on the selected target PSCell to perform the conditional execution procedure to connect to the selected target PSCell, or
• (b) maintaining the SCG state at the UE as the deactivated state without performing a RACH procedure on the selected target PSCell.

A method of wireless communication by a network node, comprising:

• operating in a multi-radio dual connectivity (MR-DC) mode with connections established with a user equipment (UE) and a source secondary node;
• changing a source secondary cell group (SCG) state associated with a source primary secondary cell group (SCG) cell (PSCell) of the source secondary node based on at least one of a request from the UE to change the source SCG state or a network condition;
• determining that the changing of the source SCG state has occurred during an evaluation process by the UE, wherein the evaluation process comprises evaluation of one or more link qualities between the UE and one or more target PSCells respectively associated with one or more target secondary nodes to select a target PSCell from the one or more target PSCells;
• and
• refraining from notifying the one or more target secondary nodes that the changing of the source SCG state has occurred during the evaluation process.
