Classification: CPC H | IPC H

Claim 8:
9. A wireless device adapted to operate in a wireless communication system, the wireless device comprising:
a memory;
a transceiver; and
a processor, operably coupled to the memory and the transceiver, and configured to perform operations comprising:
receiving a secondary cell group (SCG) configuration from a first network node,
wherein the SCG configuration includes information about cells related to a second network node;
receiving a radio resource control (RRC) release message from a first network node,
wherein the RRC release message includes a suspend configuration;
entering an RRC_INACTIVE state based on the suspend configuration included in the RRC release message;
storing the SCG configuration in the RRC_INACTIVE state;
identifying at least one valid cell from among the cells based on validity criteria,
wherein the RRC release message includes the validity criteria;
determining a primary secondary cell (PSCell) from among the at least one valid cell;
transmitting an RRC resume complete message including information about the at least one valid cell to the first network node; and
performing a PSCell addition with the PSCell based on the stored SCG configuration.
