Abstract: Technology for a relay user equipment (UE) operable to act as a relay between a remote UE and an eNodeB is disclosed. The relay UE can receive, from the eNodeB, a relay configuration message that includes one or more relay configuration parameters. The relay UE can identify relay UE information associated with one or more relay parameters of the relay UE. The relay UE can determine to act as the relay for the remote UE based on the one or more relay configuration parameters and the relay UE information. The relay UE can transmit a discovery message to the remote UE in order to establish a direct connection between the relay UE and the remote UE, wherein the relay UE is configured to relay data from the eNodeB to the remote UE via the direct convection between the relay UE and the remote UE.

Abstract: Techniques described herein may be used to enable User Equipment (UE) to switch between Radio Access Technologies (RATs) while transitioning from an inactive state to an active state. For example. a UE may connect to a base station via one type of RAT (e.g., Long-Term Evolution (LTE) RAT), enter an inactive state, and later, while transitioning from the inactive state to an active state, connect to another base station via another type of RAT (e.g., a New Radio (NR) or 5th Generation (5G) RAT). The UE may transition from one RAT to another RAT without increasing signaling between the UE and the network beyond minimal signaling involved in a transition of the UE from the inactive state to an active state. The network may further minimize signaling by determining and communicating minimized connection configuration information to the UE.
