Stakes

  • In addition to ensuring 5G-ALLSTAR project coordination, CEA-Leti is:

    • Investigating algorithms, which will be developed at the physical layer, for the terrestrial part of a 5G multi-access system. Their purpose is to mitigate the spectrum interference that occurs when several access systems share the same or adjacent bands. Interference may come from other terrestrial systems like 4G or WiFi or from satellite systems. The studies
      include not only time and frequency filtering as an option for decreasing out-of-band rejections, but also interference cancellation algorithms. The 5G NR physical layer (release 15), i.e. CP-OFDM (Cyclic Prefix Orthogonal Frequency Division Multiplexing), serves as a basis for the work

    • Contributing to the Proof of Concept. The aim of the project is to ensure technology demonstration
      of the feasibility of mmWave-based 5G access networks capable of providing broadband and low-latency 5G services. Demonstration requires CEA-Leti to produce a realtime FPGA (Field Programmable Gate Array)-based Layer 1 modem, operating in the millimeter wave band, featuring an embedded light MAC (Medium Access Control) hosted on the ARM processor of the digital board. High speed Analog to Digital and Digital to Analog Converters will be used to transmit and receive in Intermediate Frequency for the tests with a channel emulator. Off-the-shelf Radio Frequency front-end and off-the-shelf antennas will be used for airborne transmission. This approach allows the previously designed layers to be evaluated under real conditions.


OBJECTIVES

  • 5G Communication Networks are today mature enough for developing key enabling technologies that allow for extended Proof of Concepts (PoC). Although standardization of 5G is yet to be finalized, 5G players have already reached general agreement on key
    enabling technologies, architecture and deployment scenarios for 5G networks. The 5G community is now looking to translate 5G use cases, vertical industry requirements and 5G adoption ambitions into viable business cases. However, support of 5G new services and seamless connectivity across various vertical industries and highly diverse use cases still requires integration of multiple access technologies. 5G-ALLSTAR builds on the outcomes and the cooperation experience of the 5GCHAMPION project to design, develop, evaluate and trial multi-connectivity based on multiple access, combining cellular and satellite access technologies
    to support seamless reliable and ubiquitous broadband services. The project aims to validate system interoperability, to provide global connectivity and support mission critical applications of interest in European and Korean regions. To this end, 5G-ALLSTAR is developing selected technologies and targeting a set of PoCs to validate and demonstrate in a heterogeneous real setup, i) a 5G cellular mmWave access system for broadband and low-latency 5G services, ii) new radio-based feasibility of satellite access for broadband and reliable 5G services, iii) multi-connectivity support based on cellular and satellite access, iv) spectrum sharing between cellular and satellite access. The project is also actively contributing to, v) global 5G standardization including 3GPP and ETSI, focusing on multi-RAT interoperability and New Radio-based satellite access, vi) creation of cross-regional lasting synergy for 5G research, innovation and commercialization through value proposal assessment for vertical industries.


IMPACT

  • The 5G-ALLSTAR project positions Europe as a major player in 3GPP New Radio (5G) standardization via the inclusion of satellite connectivity in releases 16 and 17. Moreover, the project fosters close interaction between European and Asian ecosystems on 5G and beyond
