1. 5G Internet of Vehicles
- Basic Concepts (Frequency Bands), Advantages, Challenges
- Two camps:
(1) DSRC - a relatively mature IEEE-led solution, a vehicle-specific short-range communication technology, and end-to-end direct access. (what?)
(2) C-V2X (domestic, based on cellular network and V2X)
One is to connect to the vehicle profile communication through the base station; the other is to communicate directly between vehicles, with fewer turning points and lower delay.
①LTE-V2X: 3GPP R14 (version agreement content); resource allocation mode - mode3: centralized scheduling of base stations, mode4: terminal autonomy
②NR-V2X: 3GGP R16; resource allocation mode - mode1: under the control of the base station, mode2: the terminal independently selects
3. C-V2X working mode
(1) V2V——Vehicle-to-Vehicle
(2) V2I - vehicle and infrastructure
(3) V2N - between the vehicle and the network
(4) V2P - between cars and pedestrians
4. C-V2X communication interface - correspondence between different working modes and interfaces
(1) Uu——cellular network communication interface (used under network coverage)
(2) PC5 - short-distance interface between vehicles, people and roads (direct communication)
5. C-V2X module
(1) OBU: On-board unit
(2) RSU: road side unit
2. 5G+artificial intelligence - how to unite and what is the significance?
- process status
- algorithm
- linear regression
①Learning algorithm: least square method; gradient descent method;
② Fitting results: overfitting; underfitting; - regular term, regression model
③ Model effect judgment
(1) neural network
(2) Decision tree
