1. A method performed by a wireless device adapted to operate in a wireless communication system, the method comprising:
receiving a radio resource control (RRC) release message from a network,
wherein the RRC release message includes a measurement configuration to be used by the wireless device while in an RRC idle state or an RRC inactive state, and
wherein the RRC release message includes validity criteria for cells;
entering the RRC idle state or the RRC inactive state based on the RRC release message;
while in the RRC idle state or the RRC inactive state:
(i) performing a measurement on the cells;
(ii) checking validity of the cells based on the validity criteria for the cells;
transmitting, to the network, a first message which transits the wireless device from the RRC idle state or the RRC inactive state to an RRC connected state;
receiving, from the network, a second message including a configuration of the cells;
identifying at least one invalid cell among the cells for which the configuration of the cells is not be able to apply based on the validity of the cells; and
transmitting, to the network, a third message including information on the at least one invalid cell.
