  • Idle/Inactive Measurement Handling During Radio Resource Control State Transitions
    Publication number: 20220217563
    Abstract: According to certain embodiments, a method performed by a wireless device (110) for measurement reporting includes transmitting, to a network node (160), a first message to initiate a transition from a dormant state to a connected state. The wireless device receives, from the network node, a second message including an indication of whether the wireless device is to release or keep at least one measurement configuration for performing measurements while in the dormant state. Based on the first message, the wireless device determines whether to release or keep the at least one measurement configuration for performing measurements while the wireless device is in the dormant state.
