In addition to the initial precise alignment between the transmitter (TX) and receiver (RX), called device discovery, a constant alignment between the TX and RX is mandatory for highly directional antennas. Therefore, beam tracking and/or switching is required in time-varying scenarios. In this chapter, a beam-tracking approach based on antenna pattern information is explained. This approach is verified using channel sounder measurements and improved using artificial intelligence (AI)/reinforcement learning (RL) techniques.

摘要

In addition to the initial precise alignment between the transmitter (TX) and receiver (RX), called device discovery, a constant alignment between the TX and RX is mandatory for highly directional antennas. Therefore, beam tracking and/or switching is required in time-varying scenarios. In this chapter, a beam-tracking approach based on antenna pattern information is explained. This approach is verified using channel sounder measurements and improved using artificial intelligence (AI)/reinforcement learning (RL) techniques.
