TECHNICAL FIELD

The present disclosure relates to telecommunications technology.

BACKGROUND

Cellular vehicle-to-everything (C-V2X) allows methods for communications utilizing the ‘Uu’ interface, also referred to as the Uu reference point, and PC5 communications using the PC5 interface, also referred to as the PC5 reference point. For Long Term Evolution Uu (LTE-Uu) based communications, a vehicle-to-everything (V2X) enabled user equipment (V2X-UE) establishes a packet data network (PDN) connection with a core network and sends packets to the core network. The core network then broadcasts or unicast the packets to intended V2X-UEs. For PC5 based communications, a V2X-UE can broadcast packets directly to other V2X-UEs via the PC5 interface. However, there are challenges in facilitating ultra-reliability for certain PC5 communications.
