Modified PHY Layer for High Performance V2X Communication using 5G NR

People are increasingly relying on vehicular communities for a more safe and comfortable day-to-day car journey. So, expectation from vehicular technology is increasing more from time to time. As a result, vehicular technology is expected to support infotainment services to the traveler. Hence, the requirements for entertainment services need extra capacity along with safety services. One of the important pieces in the channel capacity is throughput. The existing IEEE 802.11p standard with the support of Dedicated Short Range Communication (DSRC) might not fulfill the required capacity in the coming days. To achieve that required throughput DSRC protocol needs to evolve. However, Multiple Input Multiple Output (MIMO) and 5G NR has the potential to improve throughput while maintaining the existing PHY layer specifications defined in the Wireless Access for Vehicular Environments (WAVE) standard. We propose a modified PHY layer of the DSRC protocol to integrate MIMO and 5G NR to enhance the existing data rate. Our experimental results show that the combination of MIMO and 5G NR can boost the throughput to 6.5 times better compared to MIMO enabled existing framework while keeping the BER (Bit Error Rate) as the same or in some cases below the combination of MIMO and DSRC.
