AMBIENT INTERNET-OF-THINGS OPERATIONS WITH A FREQUENCY SCANNING ANTENNA ARCHITECTURE

Methods, systems, and devices for wireless communications are described. The described techniques provide for an energy harvesting (EH)-capable device to indicate, to a reader wireless device, capabilities of the EH-capable device to use a frequency scanning antenna (FSA) array. In some examples, the capability report may indicate one or more modes supported by the EH-capable device, where a mode may indicate one or more operations supported by the EH-capable device using one or more antenna ports associated with the FSA array. For example, the EH-capable device may indicate a capability to communicate using two different antenna ports and may indicate a capability to perform concurrent operations using the two different antenna ports. In some examples, the mode of the EH-capable device may indicate which operations are performable using each antenna port, and the EH-capable device may communicate with the reader wireless device to determine a mode for communications.
