The ultra-dense future wireless network increases the energy consumption as well as data traffic in 6G. Therefore, energy harvesting is an appealing alternative for energy-efficient massive radio access. Simultaneous wireless information and power transfer (SWIPT) where both information and energy can be extracted from the same received RF signal is a promising research direction.
However, making use of RF interference for energy harvesting is very challenging owing to the trade-off between interference and throughput: high interference limits the throughput, whereas low interference limits the amount of RF energy harvested. Here again, AI is paramount to strike such a compromise.
