1. A method for multiple pocket-forming in wireless power transmission, the method comprising:

  • establishing, by a transmitter, a first communication connection associating the transmitter with a first receiver in response to the transmitter receiving a first communication signal from the first receiver;

    transmitting, by the transmitter, one or more first power transmission waves in a direction of the first receiver based on the first communication signal received from the first receiver;

    adjusting, by the transmitter, a phase of the one or more first power transmission waves and a gain of the one or more first power transmission waves to cause the one or more first power transmission waves to converge at a first location with respect to the first receiver in accordance with the first communication signal received from the first receiver, thereby forming a pocket of energy at the first location at which the one or more first power transmission waves converge;

    responsive to the transmitter receiving a second communication signal from a second receiver;

    establishing, by the transmitter, a second communication connection associating the transmitter with the second receiver; and

    identifying, by the transmitter, a second subset of one or more antennas from an array of antennas of the transmitter, wherein the second subset is associated with the second receiver, and wherein a first subset of one or more antennas is associated with the first receiver;

    transmitting, by the transmitter, one or more second power transmission waves in the direction of the second receiver based on the second communication signal received from the second receiver, wherein the second subset of antennas transmits the one or more second power transmission waves to the second receiver; and

    adjusting, by the transmitter, based on the second communication signal, a phase and a gain of the one or more second power transmission waves transmitted in the direction of the second receiver to cause the one or more second power transmission waves to converge at a second location respective to the second receiver, thereby forming a second pocket of energy at the second location.
