Abstract
The present teaching relates to wireless power transmission based on power waveforming. In one example, an apparatus for wireless power transmission is disclosed. The apparatus comprises: at least one antenna configured for receiving at least one wireless signal from a receiver, via a multipath channel between the apparatus and the receiver; and at least one processor configured for estimating at least one channel state information (CSI) of the multipath channel based on the at least one wireless signal, determining a power transmission waveform based on the at least one CSI, and calculating a power transfer signal based on the power transmission waveform and a reference signal. The at least one antenna is further configured for wirelessly transmitting the power transfer signal to the receiver.
