Vehicular and Aerial Communication

b5g

Intelligent connected and moving machines
- Massive mobile AR/VR/MR galsses
- Very large fleets of autonomous vehicles
- Cooperating drone swarms
- Collabortive moving robots

Access supply has been well-studied in the past
- but implication of user demand remain largely unexplored
Rethink wireless system design and content delivery for better matching the irregular user demand with the network access suplly in 5G systems
Proposed solution
- dynamic and mobile network infrastructures that intelligently leverage provisional and personal radio access equipment
  - Offer truly flexible and on-demand network architecture by involving operator- and user-owned connected machines without the associated high costs
  - Employ mobile base stations equipped with high-rate (e.g., mmWave) radio access capabilities
  - Leverage multi-radio uplink, downlink, direct device-to-device (D2D) links, as well as vehicle- and drone-assisted access

Breakthrough goal
- reliable people-aware connectivity where space-time supply and demand may be shaped opportunistically
  - User-owned machines (high-end wearables, cars, drones, etc.)
  - take a more active role in 5G+ service provisioning (especially in partial coverage situations
    - Functional disparity between the network and the user equipment is rapidly becoming blurred
Theoretical benefits
- Orders of magnitude better network capacity scaling
  - Number of base stations: K
  - Min number of antennas : n
  - Avaliable bandwidth : W
  - Network capacity = $K \times n \times W \times log(SNR)$
Practical benefits
- clearly noticeable more stable and smoother user connectivity experience
- This research accentuates the importance of people as an integral component of beyond-5G system infrastructure with multiple impacts in industry, education, and community outreach
