研究目的
Investigating the human blockage model for the 5G low-THz band communications with emphasis on the location and direction of the user in relation to the base station.
研究成果
The paper provides a human blockage model for the 5G low-THz band communications, highlighting the importance of user direction and location in relation to the base station. The model is more suitable for THz band communications than random walk models due to the significant impact of user direction changes on communication loss. Future studies could expand by integrating height and 3D domain analyses and exploring larger usage spaces.
研究不足
The model does not integrate height and 3D domain into the analyses and is limited to indoor deployment scenarios with a specific hexagonal room size.
1：Experimental Design and Method Selection:
The paper proposes a motion model in a hexagonal grid for a person carrying a user equipment, analyzing electromagnetic wave blockage using channel characteristics of the low-THz band.
2：Sample Selection and Data Sources:
The model is based on a hexagonal grid and assumes a user's movement and direction changes within this grid.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned.
4：Experimental Procedures and Operational Workflow:
The model is simulated with varying parameters such as movement probability, user width, and distance between the user and user equipment.
5：Data Analysis Methods:
The communication and blockage probabilities are theoretically examined and numerically simulated.
