Optimization of Bandwidth for Ultra-reliable and Low Latency Communication using Compression

Abstract

4G and 5G are emerging technology that provides high data rates with reliability and optimized latency, as compared to the other (LTE, CDMA, HSPA) technologies. This technology provides three types of services: mMTC (Machine Type communication) which is already been developed as part of 3GPP release 13/14, eMBB(enhanced Mobile Broadband) which provides enhanced bandwidth with moderate latency, and uRLLC(Ultra-reliable and low latency communication) which is introduced in 3GPP-release 15/16 and is still under development. Ultrareliable and low-latency communication service requires strict latency and reliability. URLLC focuses on applications that expect precise real-time communication for autonomous vehicles, advanced power grids, device communication for accidents and emergencies, industrial communication (e.g. wireless operation of equipment), and health care (e.g. remote operations and monitoring). The proposed research focuses on the efficient utilization of bandwidth at Layer 2 of the protocol stack for ultra-reliable and low-latency applications in 5G/4G or any other RAT (Radio Access Technology) by using a novel header compression approach called “Robust Header Compression” and analysis its impact for network and upper layers header compression for the application of telesurgery. RoHC is implemented and data is simulated. Comparison is made on the bases of the original and compressed header. This compression approach compresses the IP,UDP and RTP header. Multiple compression scenarios have been analyzed and compression ratios are measured for URLLC telesurgery application.
