INSIGHTS ACROSS THE 5G NEW RADIO (NR) ECOSYSTEM AND AN OVERVIEW OF ITS PHYSICAL LAYER

Shivam Thakur, Siddhi Sharma

Abstract: The most imminent technology that Telecom sector is striving to deploy is the next generation mobile phone system IMT 2020, which is currently being disseminated as “5G”. There have been significant development in the research on fifth generation networks. Apart from being an evolution to broadband services (like increase in throughput, latency reduction, ultra-reliability, more bandwidth availability to users, etc.), it acts as a proverbial gateway to a plethora of services like Narrowband IOT, Machine-to-machine communication, Vehicle to anything(V2X), etc. All the stakeholders such as regulatory bodies, standardization authorities, industrial fora , mobile operators and workers must work in unison to bring 5G to fruition. The recently launched 3GPP 38 series expounds the specifications of 5G RAN, here known as 5G NR. In this paper, we aggregate the 5G related information coming from various stakeholders in order to have a comprehensive overview of 5G and to provide a succinct survey of the envisioned 5G technologies as per the 3GPP specifications.

Keywords: 5G NR, LTE, IOT, RAN, BBU, OFDMA, Beamforming, NFV, FDD, TDD, PAPR.
