  48. 48. Project Vision: “to provide technical solutions that enable future 5G networks to act as dependable communications backbone for the Factories of the Future” Valencia, 19.06.2019 2
  49. 49. Project Brief • Clear5G-Converged wireless access for reliable 5G MTC for factories of the future (FoF) Valencia, 19.06.2019 3 • Horizon2020 EU-TW collaboration • Sept. 2017 – Feb. 2020 • Focus on 5G radio network for FoF (PHY, MAC, NET) • Coordinator: University of Surrey • Coordinator TW: Institute for Information Industry • Technical Manager: TNO • Objectives: to design, develop, validate, and demonstrate an integrated convergent wireless network for Machine Type and Mission Critical Communication (MTC/MCC) services for Factories of the Future (FoF)
  50. 50. Clear5G network view • While parts of the underlying communications infrastructure will be public networks, within factories there will be private (physically or virtually) factory wide 5G networks tailored to the particular needs of the individual site • Continuous monitoring while products or parts are within the logistics section of the production chain • Spectrum regulation and management plays a significant role Valencia, 19.06.2019 4
  51. 51. Challenges and Clear5G KPI’s The Industrial environment is challenging for wireless connectivity, e.g. both large- and small- scale fading (predictable?) • Massive connectivity • Coverage, reliability and latency • Heterogeneity (private and public network, different radio technologies) Valencia, 19.06.2019 5 Clear 5G KPI Targeted value Latency (end-to-end) Down to 1 ms Reliability Up to 99.999% Connection density Up to 100 nodes per 1 m3 Security PHY framework Heterogeneity (convergent air interfaces) Coexistence of various radio interfaces, and various FoF use cases Energy efficiency (Device battery life) >15 year battery life

  54. 54. Example: Network slicing in a factory network • Slicing enables operators to support different network instances on the same infrastructure • FoF as one of the slices, or • Different FoF use cases (e.g. URLLC, non- URLLC) may be served by different slices • URLLC: local controller • Non-URLLC: controller in the cloud • FoF slices may be provided by a public network operator, or a physically private network.

  89. 89. TONIC Research Group Outline 2 • Introduction • III Contributions • NTU Contributions • Summary
  90. 90. TONIC Research Group Clear5G – WP3 3 • WP3 provides MAC-layer air interface enhancements for the MTC in the FoF use cases, including both the control plane and the user plane. • WP3 investigates cross-layer (PHY and MAC) IoT traffic management and the impact of heterogeneous radio networks. • Task 3.1: Random Access Enhancement • Task 3.2: Adaptive MAC Protocol for mMTC and uMTC • Task 3.3: Heterogeneous Radio Access • Task 3.4: Implementation
  91. 91. TONIC Research Group Clear5G – WP3 4
  92. 92. TONIC Research Group Clear5G – Task 3.2 5 • Task 3.2: Adaptive MAC protocol for mMTC and uMTC • Task 3.2 proposes an adaptive MAC protocol, which works in a contention-like manner in low-load traffic conditions to reduce the access latency. Moreover, the proposed MAC protocol will work in a scheduling-like manner in high-load traffic conditions to increase the system throughput and reliability.
  93. 93. TONIC Research Group Clear5G – Roles of III and NTU 6 • III (task leader) contributed to the design of MAC scheduler for massive connection, in addition to exploring designing flexible MAC concepts for reconfiguration of the amount of resources for RACH, system signaling, scheduling of low-latency users, etc. • NTU proposed designs of low latency random access for massive MTC, with the coexistence of multiple radio access technologies.
  94. 94. TONIC Research Group III Contributions (D3.2) 7 • III has designed a MAC-layer mechanism that performs resource allocation to users adaptively either in OMA or NOMA. • Code-domain NOMA (SCMA or LDS) and OMA (OFDMA or SC-FDMA) uplink multiple access schemes. • F candidate UEs to be allocated either in F resource blocks (OMA) or V>F resource blocks (NOMA) Omax: max modulation order NOMA BLER based on the worst SNR • Choose the MA with the best throughput (SOMA or SNOMA)
  95. 95. TONIC Research Group III Contributions (D3.2) 8 • Evaluation results with low and high SNRs • Low SNR: UE power = -20dBm • High SNR: UE power = -10dBm • Latency of the proposed mechanism can always achieve the lowest irrespective of the conditions Low SNR High SNR
  96. 96. TONIC Research Group NTU Contributions (D3.2) 9 • Two-tier architecture with heterogeneous radios • Tier-1 (to/from base station): 5G • Tier-2 (between IIoT devices): short-range radio (6TiSCH) • Latency reduction • Pure 5G -> two-tier: reduce bottleneck at the base station • Pure 6TiSCH -> reduce multi-hop delay • Use NOMA at tier-1 can further • reduce latency • Some interesting results for • IIoT devices
  97. 97. TONIC Research Group Data Characteristics of IIoT Devices 10 • IIoT devices are deployed to collectively gather (or report) data required by the target application • Collected data by individual devices is often related • Conventionally traffic from individual UEs are considered independent • Contention of radio resource • Conventionally, it matters to provide QoS to each UE • For IIoT devices, it is possible that they contend resource to transmit same (similar) data • Does it make sense to provide QoS to each IIoT devices without considering the data they carry? • Consider the problem of pairing & scheduling NOMA UEs
  98. 98. TONIC Research Group Sum-Rate Maximization Scheduling 11 • Conventional approach for NOMA user pairing is to maximize the sum data rate of the pair • machines are indexed in decreasing channel gain • Achievable rate of each machine • P is the transmission power of each machine • G accounts for the spectral gap to Shannon capacity
  99. 99. TONIC Research Group Overall Comparison 12 • NOMA under sum-rate maximization could perform worse than OMA
  100. 100. TONIC Research Group Resource Minimization Scheduling 13 • Sum rate maximization is typically good for backlogged traffic sources (e.g. FTP), yet is it the case to M2M communications used for data gathering? • Resource (time) needed for machine k • is the size of data • Required resource for a given pair • “Faster” machine needs to wait for the slower
  101. 101. TONIC Research Group Waiting-Time Minimization 14 • Waiting time inside a time slot indicates a waste of radio resource • Maximizing resource utilization is beneficial to resource minimization • Scheduling metric • Scheduling pairs in decreasing metric value
  102. 102. TONIC Research Group Overall Comparison 15 • Radio resource minimization and waiting-time minimization achieve the desired performance
  103. 103. TONIC Research Group Summary • Reducing latency in FoF using NOMA • Adaptive MAC to choose the best multiple access scheme depending on the achievable throughput • Two-tier architecture provides more flexibility with further reduction in end-to-end latency • For IIoT devices with limited amount of data to send, throughput maximization does not necessarily lead to latency minimization • Better user NOMA pairing and scheduling methods can be designed optimize latency performance in FoF 16
