System Architecture for Intelligent Environment-Aware Wireless Communications

Abstract

The integration of communications and wireless sensing using the same frequency spectrum is likely to be one of the key features beyond 5G wireless systems, enabling digital transformation to its full potential. Therefore, future wireless communication networks will have to become intelligent, meaning environment-aware, adaptive and parsimonious in terms of radio resources and energy. In this chapter, we propose a system architecture that enables the introduction of intelligent environment-aware wireless communications. Special attention has been paid to the description of the wireless channel in the database with a set of radio rays, generated by the calibrated ray tracing using the ray bouncing method. The proposed approach enables straightforward calculation of the channel impulse response enriched with information about the angle of arrival and angle of departure for the band-limited multiple antenna wireless communication systems. The proposed architecture introduces the concept of local and global agents, used for retrieving associated parameters from the user requirements and the existing radio channel characteristics data.
