Abstract

Device to device (D2D) communication can be performed with packet data convergence protocol (PDCP) based encapsulation without internet protocol (IP) addressing. The non-IP D2D PDCP-encapsulated communication can further include two forms of secure data transfer. A first non-IP D2D PDCP-encapsulated communication can be a negotiated non-IP D2D PDCP-encapsulated communication. A second non-IP D2D PDCP-encapsulated communication can be a non-negotiated non-IP D2D communication. The non-negotiated non-IP D2D PDCP-encapsulated communication can include a common key management server (KMS) version and a distributed KMS version. The encapsulated communication can be used with various protocols, including a PC5 protocol (such as the PC5 Signaling Protocol) and wireless access in vehicular environments (WAVE) protocols.

Claims20

Dependent claims

A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a processor of a user equipment (UE), cause the processor to:

decode a packet data convergence protocol (PDCP) protocol data unit (PDU) header comprising a PDCP service data unit (SDU) type field indicating a non-internet protocol (non-IP) SDU;
decode the PDCP PDU with the PDCP header to extract a PDCP SDU;
and
decode the PDCP SDU to extract a non-IP vehicle message, wherein to decode the PDCP SDU comprises to decode an indicator within the PDCP SDU that identifies a non-IP vehicle message type.
