1. A method for wireless power transmission comprising:

  • receiving, by an antenna of a receiver, a plurality of radio frequency (RF) power waves from a transmitter that constructively interfere at a location of the receiver;

    receiving, by a communications component of the receiver and using a pre-existing wireless protocol that includes handshakes, from the transmitter a first request for one or more power values associated with reception of the plurality of RF power waves at the receiver;

    in response to the first request and without requiring an additional request for power values from the transmitter, continuously and consecutively executing respective iterations of a loop executed at the receiver, each respective iteration of the loop bypassing the handshakes and other overhead processes associated with the pre-existing wireless protocol, and each respective iteration of the loop including;

    measuring one or more power values associated with reception of the plurality of RF power waves received at the receiver during the respective iteration of the loop;

    transmitting a respective power message to the transmitter, wherein the respective power message contains at least the measured one or more power values; and

    proceeding to a next respective iteration of the loop in accordance with a determination that one or more buffers of the communications component that are configured to store the plurality of power messages are not full;

    receiving, by the antenna of the receiver, a plurality of adjusted RF power waves from the transmitter, wherein the plurality of adjusted RF power waves are adjusted by the transmitter in accordance with the one or more power values in the plurality of power messages;

    in accordance with determining that the one or more buffers of the communications component of the receiver are full;

    transmitting, by the communications component of the receiver and using the pre-existing wireless protocol, an indicator bit indicating that the one or more buffers are full; and

    upon receiving, from the transmitter, a second request for one or more power values associated with reception of RF power waves at the receiver;

    resetting, by the communications component of the receiver, at least one buffer of the one or more buffers of the communications component.
