Claim 0:
1. A method performed by a user equipment (UE) configured to operate in a wireless communication system, the method comprising:
receiving, from a network, a logged measurement configuration including an event type for triggering the UE to perform logging of available measurements;
while the UE is in RRC_IDLE and RRC_INACTIVE:
1) Based on the event type being set to a first event type: i) performing the logging at regular time intervals only when the UE is in “any cell selection” state and ii) performing the logging upon transition from the “any cell selection state” to “camped normally” state,
wherein the logging includes information indicating detection of no suitable cell or no acceptable cell found, based on the UE being in the “any cell selection” state; and
2) Based on the event type being set to a second event type, performing the logging at regular time intervals only when a condition in which a serving cell quality is worse than a serving cell quality threshold is met; and transmitting, to the network, results of the logging.
