Abstract

Claims (44)

1 . A method comprising:

receiving energy parameters from a backscatter communication device;

receiving an energy critical message from the backscatter communication device;

instructing the backscatter communication device to send frequent messages in response to receiving the energy critical message from the backscatter communication device;

determining a configuration for a Reconfigurable Intelligent Surface (RIS) cluster to supply energy to the backscatter communication device based on the energy parameters and the frequent messages;

causing the RIS cluster to supply energy to the backscatter communication device based on the configuration; and

saving the configuration for a future use in causing the RIS cluster to supply energy to the backscatter communication device based on the configuration.

2 . The method of claim 1 , further comprising discovering the RIS cluster.

3 . The method of claim 1 , further comprising maintaining a database of the backscatter communication device and the RIS cluster.

4 . The method of claim 1 , further comprising sending the configuration to the RIS cluster.

5 . The method of claim 1 , wherein the energy parameters comprise at least one of a power status, a device mode, and RIS properties expected.

6 . The method of claim 1 , wherein the frequent messages comprise an Identifier (ID) associated with the backscatter communication device.

7 . The method of claim 1 , further comprising:

determining energy harvest levels from the backscatter communication device; and

providing feedback to RIS cluster.

8 . A system comprising:

a memory storage; and

a processing unit coupled to the memory storage, wherein the processing unit is operative to:

receive energy parameters from a backscatter communication device;

receive an energy critical message from the backscatter communication device;

instruct the backscatter communication device to send frequent messages in response to receiving the energy critical message from the backscatter communication device;

determine a configuration for a Reconfigurable Intelligent Surface (RIS) cluster to supply energy to the backscatter communication device based on the energy parameters and the frequent messages;

cause the RIS cluster to supply energy to the backscatter communication device based on the configuration; and

save the configuration for a future use in causing the RIS cluster to supply energy to the backscatter communication device based on the configuration.

9 . The system of claim 8 , wherein the processing unit is further operative to discover the RIS cluster.

10 . The system of claim 8 , wherein the processing unit is further operative to maintain a database of the backscatter communication device and the RIS cluster.

11 . The system of claim 8 , wherein the processing unit is further operative to send the configuration to the RIS cluster.

12 . The system of claim 8 , wherein the energy parameters comprise at least one of a power status, a device mode, and RIS properties expected.

13 . The system of claim 8 , wherein the frequent messages comprise an Identifier (ID) associated with the backscatter communication device.

14 . A non-transitory computer-readable medium that stores a set of instructions which when executed perform a method executed by the set of instructions comprising:

receiving energy parameters from a backscatter communication device;

receiving an energy critical message from the backscatter communication device;

instructing the backscatter communication device to send frequent messages in response to receiving the energy critical message from the backscatter communication device;

determining a configuration for a Reconfigurable Intelligent Surface (RIS) cluster to supply energy to the backscatter communication device based on the energy parameters and the frequent messages;

causing the RIS cluster to supply energy to the backscatter communication device based on the configuration; and

saving the configuration for a future use in causing the RIS cluster to supply energy to the backscatter communication device based on the configuration.

15 . The non-transitory computer-readable medium of claim 14 , further comprising discovering the RIS cluster.

16 . The non-transitory computer-readable medium of claim 14 , further comprising maintaining a database of the backscatter communication device and the RIS cluster.

17 . The non-transitory computer-readable medium of claim 14 , further comprising sending the configuration to the RIS cluster.

18 . The non-transitory computer-readable medium of claim 14 , wherein the energy parameters comprise at least one of a power status, a device mode, and RIS properties expected.

19 . The non-transitory computer-readable medium of claim 14 , wherein the frequent messages comprise an Identifier (ID) associated with the backscatter communication device.

20 . The non-transitory computer-readable medium of claim 14 , further comprising:

determining energy harvest levels from the backscatter communication device; and

providing feedback to RIS cluster.
