Beyond-5G wireless Tbps Scenarios and Requirements

Abstract : The BRAVE project proposes to investigate innovative technologies allowing an efficient radio-communication usage of the 90GHz-200GHz spectrum. It will contribute to the emergence of ultra-high throughput and capacity beyond-5G (B5G) wireless communication systems. The wideband Single-Carrier (SC) waveform will be studied as an enabler for the migration of 5G networks towards Tbps systems. Achieving PHY-layer high spectrum efficiency under low energy consumption constraint is the main challenge. The BRAVE project, defines six major PHY-related objectives: (i) the partners will elaborate analog and digital processing solutions that; (ii) operate above 90 GHz, based on; (iii) new efficient and ultra-wideband SC waveforms; the specific channel properties, and (iv) RF impairments are modelled and considered in the waveform design; (v) the integration into a simulation link- and system-level platform permits the assessment of the proposed technology in realistic scenarios; (vi) and, the project identifies the spectrum regulation constraints and requirements. This document presents a description of some applicative scenarios and use cases in which ultra-high throughput (of order of Tbps) wireless communication systems are envisaged in bands above 90 GHz: kiosk download, wireless backhauling, Fixed Wireless Access (FWA), drones, server farm, hotspots with Augmented Reality (AR) or Virtual Reality (VR) multiple users, inter- or intra-chip communications. An insight on the spectrum availability to deploy such wireless communications is provided based on the French National Frequency Agency (ANFR) guidance and recommendations. Key performance indicators are also given to evaluate and compare the different achieved technical performances and solutions. A preliminary list of KPIs per scenario with system parameters and performance requirements is also provided in this technical deliverable. It is worth mentioning that depicted KPIs values constitute a preliminary and an early shaping of targeted parameters for future Tbps wireless communications, that still need to be validated and confirmed. The BRAVE project will contribute to this effort in further work packages (WP2 and WP3) mainly for scenarios as “kiosk”, FWA or mesh backhauling. This document gives a first version of BRAVE spectrum opportunities and scenarios. The spectrum regulation aspects will be completed mid-2019 in deliverable D1.1, while the scenarios will be updated and finalized at the end of the project in deliverable D1.2.
