EV2X mobility support for mode 3.5/RSU scheduled mode

An apparatus comprising:

• a processor;
• and
• memory coupled with the processor, the processor configured to:
• transmit a request message to an access network node to indicate a first user equipment (UE) associated with the apparatus is switching from a first scheduling mode to a peer UE scheduling mode;
• receive a message from the access network node indicating a state change to allow the peer UE scheduling mode;
• and
• transmit a resume message to the access network node to indicate that the first UE is switching from the peer UE scheduling mode to the first scheduling mode based at least in part on the first UE being within an area identified by an area identifier.

A method for managing an operation mode of a first user equipment (UE) in device-to-device communication implemented by an access network node, comprising:

• receiving, by the access network node, a request message from the first UE to indicate the first UE is switching from a first scheduling mode to a peer UE scheduling mode;
• transmitting, by the access network node, a message to the first UE indicating a state change to allow the peer UE scheduling mode;
• and
• receiving, by the access network node, a resume message from the first UE to indicate that the first UE is switching from the peer UE scheduling mode to the first scheduling mode based at least in part on the first UE being within an area identified by an area identifier.
