    Abstract: Systems and methods for using a relay user equipment (UE) to transport data of interest received from a first remote UE to a second remote UE on a UE to UE relay within a wireless communication system are discussed herein. These methods may be performed at Layer 2 of a protocol stack of the wireless communication system. Data packets sent on the UE to UE relay may include an adaptation header including routing information (e.g., Layer 2 addresses, a bearer-specific index, etc.) for the UE to UE relay. An adaptation layer may accordingly be provided within Layer 2 to decode these adaptation headers. In some cases, a per-bearer approach may be used to map between individual direct bearers of a hop by hop path configuration of the UE to UE relay. Embodiments eschewing the adaptation header and instead using logical channel identifiers (LCIDs) to make routing indications are also described.

    Abstract: A communication method for exposing a user plane event includes allowing an NF entity to subscribe to the user plane event by sending a request to a UPF entity through an SMF entity. The SMF entity forwards requests and responses sent between the NF entity and the UPF entity. Because the SMF entity transparently transmits requests and response messages between the NF entity and the UPF entity, the impact on the performance of the SMF entity is minimized.
