Abstract
A method for measuring a carrier in a deactivated state. The method includes receiving a configuration mode that does not take effect immediately by a user terminal (UE). If a deactivation control signal for a carrier is received by the UE or if a carrier timer of the UE expires, then the method includes switching the carrier from an activated state to a deactivated state, and measuring the carrier in deactivated state by the UE. Alternatively, if an activation control signal for a carrier in the deactivated state that is being measured is received by the UE, the method includes terminating measurement of the carrier in the deactivated state by the UE. Through controllable deactivated carrier measurement, the UE reduces battery power consumption and improves system performance. Embodiments also include an apparatus for measuring a carrier in deactivated state, a base station, and computer-readable storage medium for performing the method.
