Description	The safe and secure communication of multiple vehicles require dependable wireless communication link. Due to the vehicle mobility the radio propagation conditions is strongly varying leading to non- stationary propagation conditions. In this task a wireless measurement and geometry based real-time wireless-link modelling concept will be investigated and developed.
Main output	Due to the vehicle mobility the radio propagation conditions is strongly varying, leading to non-stationary propagation conditions. AIT will device a radio measurement system based on a software defined radio platform enabling the simultaneous measurement of the communication channels between multiple vehicles. Two spectrum and bandwidth definitions for IEEE 802.11p and 5G device-to-device (D2D) links will be used in our measurement campaign. The channel measurement data will be used to design appropriate geometry based channel models that enable the repeatable test of connected autonomous driving algorithms without the need for expensive drive experiments. AIT will use the obtained multi-vehicle channel models to design an abstracted real-time link-level emulation on packet level for IEEE 802.11p and for 5G D2D links. The packet-level emulation will be interfaced with the V2X verification and validation platform of AVL.
BB category	Methodology (for SW/HW development)
Baseline	Experience is coming from past measurement campaigns, a ray tracing software packages developed at AIT, a geometry based stochastic modelling technique developed at AIT, currently running projects on SDR prototyping (REALTIME) and single link emulation (ENABLE- S3).
