Abstract
The present disclosure provides procedures for early synchronization based on Idle mode measurements to enable fast connection establishment and resumption on transition to a Connected mode. When transitioning () to a Connected state, the UE selects one or more cells/frequencies for which in addition to the target cell configured/activated by the network to initiate early synchronization () prior to transition to the Connected state. When the UE receives () a message from the network requiring the UE to synchronize with a target cell in a target frequency, the UE determines () if the message from the network indicates that the UE shall configure or add a target cell, that is not the PCell, for which the UE has synchronized and, if so, uses the synchronization information to initiate () a random access procedure towards the target cell configured/activated by the network.
