  4. 4. ⓒ 2014. all rights reserved.ⓒ 2014. Samsung Electronics Co.,Ltd. all rights reserved. Open Interconnect Consortium (OIC) 5 / 10 • A single connectivity framework for IoT devices across multiple vertical markets using common interoperable approach • Secure and reliable device discovery • Intelligently manages the flow of information, regardless of form factor, operating system or service provider. • OIC develops standards and open source code spanning multiple OSs and platforms • Initial open source code available in Sept. 2014
  5. 5. ⓒ 2014. all rights reserved.ⓒ 2014. Samsung Electronics Co.,Ltd. all rights reserved. V2X Standards/Building blocks 6 / 10 • LTE is increasingly being used to provide V2I connectivity • DSRC provides connectivity on top of 802.11 PHY/MAC • WAVE protocol provides resource management and security • Provides an abstraction layer for vehicle applications, managing communication for multiple concurrent sessions spanning all modes (V2V, I2V, I2I), and all methods of transmission (LTE, radar, WiFi, etc.) • V2X gateway for routing heterogeneous links • Regulatory bodies endorse standards as component building blocks within the overall framework • Focus on safety applications and interoperability • Spectrum issues PHY/MAC Network/Application Layer ITS Framework
  6. 6. ⓒ 2014. all rights reserved.ⓒ 2014. Samsung Electronics Co.,Ltd. all rights reserved. V2X Technical Challenges 7 / 10 Traffic: Low-latency/high-data rate applications Access: Large node density variations / short link lifetimes Network: Optimal architecture
  7. 7. ⓒ 2014. all rights reserved.ⓒ 2014. Samsung Electronics Co.,Ltd. all rights reserved. 3GPP Standards Roadmap 8 / 10 • Massive-scale resource allocation with low overhead • Feedback mechanisms targeting vehicular speeds • Low latency and critical control message support Rel-14: V2X • Low-cost UE category with reduced RF/baseband functionality • Optimized PHY/MAC for periodic fixed-size data packets Rel-13: Machine Type Communication (MTC) • Network-assisted or ad-hoc D2D broadcast communication • Power-efficient, scalable device discovery Rel-12 D2D 2014 2015 2016
  8. 8. ⓒ 2014. all rights reserved.ⓒ 2014. Samsung Electronics Co.,Ltd. all rights reserved. V2X and 5G 9 / 10 New requirements/services for V2X: - Targeting 1 ms end-to-end latency (in the RAN) - Ubiquitous coverage (no cell-edge) - Flexible support for multiple V2X modes (V, P, I) - High-data rate software services for the vehicle (> 1 Gbps) Challenges: - Centralized vs. distributed control - Data management for V2X - RF/Antenna design - Infrastructure topology Samsung 5G “rainbow of requirements”
