Ue-to-network relay initiation and configuration

An apparatus of a relay user equipment (UE) operable to decode a sidelink discovery configuration relay information element (IE) received from an eNodeB, the apparatus comprising:

• memory;
• and
• one or more processors configured to:
• decode, at the relay UE, a system information block (SIB) received via a broadcast from the eNodeB, wherein the SIB includes the sidelink discovery configuration relay IE that includes one or more sidelink discovery configuration relay parameters;
• and
• perform, at the relay UE, a relay related sidelink operation with a remote UE based in part on the one or more sidelink discovery configuration relay parameters.

An apparatus of a relay user equipment (UE) operable to act as a relay between a remote UE and an eNodeB, the apparatus comprising:

• memory;
• and
• one or more processors configured to:
• receive, from the eNodeB, a relay configuration message that includes one or more relay configuration parameters;
• identify relay UE information associated with one or more relay parameters of the relay UE;
• determine, at the relay UE, to act as the relay for the remote UE based on the one or more relay configuration parameters and the relay UE information;
• and
• transmit, from the relay UE, 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 connection between the relay UE and the remote UE.
