AI Technical Summary
Existing wireless power supply and collaborative communication systems suffer from problems such as small coverage area, low reliability for weak users, and difficulty in offsetting multiplicative fading, making it difficult to meet the needs of full-space, large-scale Internet of Things scenarios.
An active simultaneous transmit and reflect smart reflector (ASR) is introduced to transmit and reflect radio frequency signals in the downlink through an energy splitting protocol to power the terminal. In the uplink, a cooperative non-orthogonal multiple access method is used to improve the reliability of information transmission and utilize the decoding and forwarding of signals from the remote user by the near-end user.
It significantly reduces multiplicative fading across the entire space, improves energy harvesting efficiency and system throughput, enhances user fairness and uplink reliability, and does not significantly increase hardware costs.
