• a processor configured to receive an indicator from a user equipment (UE) when the UE is in an RRC connected mode, wherein the indicator indicates an availability of the one or more logged measurements by the UE, to transmit an information request to request a report of the one or more logged measurements, and to receive the report of the one or more logged measurements.

A user equipment (UE) capable of reporting logged measurements in a wireless communication system, the UE comprising:

• a processor configured to receive a measurement configuration from a network when the UE is in an RRC connected mode, to log one or more measurements based on the measurement configuration after the UE transitions to an RRC idle mode, and to transmit an indicator to the network, wherein the indicator indicates an availability of the logged measurements.
