Method, system, and apparatus for wireless power transmission based on power waveforming

An apparatus for wireless power transmission, comprising:

• a plurality of antennas configured for
• receiving a first wireless signal from a first receiver, via a first multipath channel between the apparatus and the first receiver, and
• receiving a second wireless signal from a second receiver, via a second multipath channel between the apparatus and the second receiver;
• and
• at least one processor configured for
• estimating a first CSI of the first multipath channel based on the first wireless signal,
• estimating a second CSI of the second multipath channel based on the second wireless signal,
• determining, based on the first CSI and the second CSI, a first power transmission waveform for wirelessly transmitting power to the first receiver and a second power transmission waveform for wirelessly transmitting power to the second receiver,
• determining a composite power transmission waveform based on a combination of the first and second power transmission waveforms, and
• calculating a composite power transfer signal based on the composite power transmission waveform and a reference signal,
• wherein the plurality of antennas are further configured for wirelessly transmitting the composite power transfer signal to the first and second receivers.

A system for simultaneously transmitting wireless power and data, comprising a transmitter and a receiver, wherein the transmitter comprises:

• at least one antenna configured for receiving at least one wireless signal from the receiver, via a multipath channel between the transmitter and the receiver;
• and
• at least one processor configured for
• estimating at least one CSI of the multipath channel based on the at least one wireless signal,
• determining, based on the at least one CSI, a power transmission waveform and a data waveform, and
• calculating a composite signal based on the power transmission waveform, the data waveform, a power reference signal, and a data reference signal,
• wherein the at least one antenna is further configured for wirelessly transmitting the composite signal to the receiver.
