Abstract

Embodiments of the present disclosure relate to a method of operating an internet-of-things (IoT) device. An internet-of-things device with an energy storage is provided. At least one energy harvest window for the internet-of-things device is provided during which energy provided by the network device is stored in the energy storage in a wireless manner. The energy harvest window takes place before a discontinuous reception time window and/or before a paging occasion. Moreover, a system for operating an internet-of-things (IoT) device is described.

First claim

The invention claimed is:

1. A method of operating an internet-of-things (IoT) device, the method comprising the steps of:
providing an internet-of-things device with an energy storage, and
providing at least one energy harvest window for the internet-of-things device during which energy provided by a network device is stored in the energy storage in a wireless manner, wherein the energy harvest window takes place before a discontinuous reception time window and/or before a paging occasion.

2. The method according to claim 1 , wherein the at least one energy harvest window is provided by a network to which the internet-of-things device and the network device are connected.

3. The method according to claim 1 , wherein the at least one energy harvest window is defined by duration, bandwidth, frequency and/or power.

4. The method according to claim 1 , wherein two different kinds of energy harvest windows are provided.

5. The method according to claim 4 , wherein the different kinds of energy harvest windows are different with regard to duration, bandwidth, frequency and/or power.

6. The method according to claim 4 , wherein a first kind of energy harvest window takes place before the discontinuous reception time window, and wherein a second kind of energy harvest window takes place before the paging occasion.

7. The method according to claim 1 , wherein the at least one energy harvest window takes place immediately before the discontinuous reception time window and/or immediately before the paging occasion such that the at least one energy harvest window depends on the discontinuous reception time window and/or the paging occasion.

8. The method according to claim 1 , wherein the at least one energy harvest window is independent of the discontinuous reception time window and/or the paging occasion.

9. The method according to claim 1 , wherein a pause takes place between the at least one energy harvest window and the discontinuous reception time window and/or between the at least one energy harvest window and the paging occasion.

10. The method according to claim 1 , wherein the at least one energy harvest window for the internet-of-things device is shorter than an energy transmission window of the network device.

11. The method according to claim 1 , wherein the internet-of-things device has a communication circuit with a transmission part and/or a reception part.

12. The method according to claim 11 , wherein the communication circuit has a clock capable of synchronizing the internet-of-things device to the at least one energy harvest window.

13. The method according to claim 11 , wherein the internet-of-things device has a sensor that is coupled to the communication circuit.

14. The method according to claim 1 , wherein the energy stored is sufficient for a subsequent transmission done by the internet-of-things device.

15. The method according to claim 1 , wherein the energy storage is a capacitor or a battery.

16. The method according to claim 1 , wherein the network device is a base station.

17. A system for operating an internet-of-things (IoT) device, wherein the system comprises a network, a network device as well as an internet-of-things device with an energy storage, wherein the network is configured to define at least one energy harvest window for the internet-of-things device during which energy provided by the network device is stored in the energy storage in a wireless manner, wherein the energy harvest window takes place before a discontinuous reception time window and/or before a paging occasion.

18. The system according to claim 17 , wherein the internet-of-things device and the network device are embedded in the network such that the network device is configured to transmit a signal via the network to the internet-of-things device that is configured to receive the signal.
