Energy Harvesting in Cellular Communications

A system can facilitate broadband cellular communications with user equipment via a group of antennas of the system, wherein the group of antennas comprises multiple-input multiple-output antennas. The system can determine channel state information of user equipment for which broadband cellular communications are enabled via the group of antennas. The system can purpose an antenna element of the group of antennas for energy harvesting based on the channel state information failing to satisfy an information exchange criterion. The system can harvest, via the antenna element, non-contributory interference plus noise signals as electrical energy. The system can direct the electrical energy to a processing circuit involved in an information transmission task.
