Abstract

The present invention relates to a system for controlling energy transmission from a transmitter to at least one device, in particular network device, the system comprising: a controller which is configured to receive feedback information on energy transmission and/or on data transmission from the device and/or another device; and a mapper which is configured to allocate the device to an energy transfer resource based on the feedback information.

Claims

1. A system for controlling energy transmission from a transmitter to at least one network device, the system comprising:

a controller, configured to receive feedback information on energy transmission and/or on data transmission from the at least one network device, wherein the feedback information comprises channel state information;

a mapper, configured to allocate the at least one network device to an energy transfer resource based on the feedback information, wherein the allocation is further based on a beamformer designed from the channel state information; and

a sender, configured to generate a signal for the at least one network device based on the feedback information, wherein the sender is further configured to generate the signal to maximize an energy transmission and a data transmission to the at least one network device with respect to a quality of service (QoS) constraint to be met for at least one further device.

2. The system according to claim 1, wherein the controller is further configured to request the feedback information from the at least one network device.

3. The system according to claim 1, wherein the feedback information comprises:

location-related information;

energy-related information; and

/or

quality-of-service (QoS)-related information.

4. The system according to claim 1, wherein the controller is further configured to receive the feedback information

substantially continuously;

and/or

discretely, in a periodic manner and/or in an event-based manner.

5. The system according to claim 1, wherein the controller is further configured to receive the feedback information as part of a data signal that carries the feedback information and further data.

6. The system according to claim 1, wherein the mapper is further configured to allocate the at least one network device to:

different frequency bands;

different time slots;

different symbols and/or subcarriers;

different antennas; and

/or

different antenna beams.

7. A method, comprising:

receiving, by a system, feedback information on energy transmission and/or on data transmission from at least one network device, wherein the feedback information comprises channel state information;

allocating, by the system, the at least one network device to an energy transfer resource based on the feedback information, wherein the allocation is further based on a beamformer designed from the channel state information; and

generating, by the system, a signal for the at least one network device based on the feedback information to maximize an energy transmission and a data transmission to the at least one network device with respect to a quality of service (QoS) constraint to be met for at least one further device.

8. The method according to claim 7, wherein the method further comprises:

requesting the feedback information from the at least one network device.

9. A non-transitory computer-readable medium having processor-executable instructions stored thereon for controlling energy transmission from a transmitter to at least one network device, wherein the processor-executable instructions, when executed, facilitate performance of the following:

receiving feedback information on energy transmission and/or on data transmission from the at least one network device, wherein the feedback information comprises channel state information;

allocating the at least one network device to an energy transfer resource based on the feedback information, wherein the allocation is further based on a beamformer designed from the channel state information; and

generating a signal for the at least one network device based on the feedback information to maximize an energy transmission and a data transmission to the at least one network device with respect to a quality of service (QoS) constraint to be met for at least one further device.

10. The non-transitory computer-readable medium according to claim 9, wherein the processor-executable instructions, when executed, further facilitate:

requesting the feedback information from the at least one network device.
