Systems and methods for communication in passive/semi-passive internet-of-things

1 . A wireless communication method, comprising:

determining, by a wireless communication node, an identification related to a wireless communication device; and

sending, by the wireless communication node to the wireless communication device, an authentication instruction message,

wherein the authentication instruction message comprises a preamble sequence, an instruction code, the identification related to the wireless communication device, and an identification of the wireless communication node, that are arranged in above order along a time domain.

2 . The wireless communication method of claim 1 , further comprising:

receiving, by the wireless communication node, a response message acknowledging the authentication instruction message; and

determining, by the wireless communication node, that the wireless communication device is authenticated in response to determining that the response message indicates that the identification of the wireless communication node has been received correctly.

3 . A non-transitory computer-readable medium having code stored thereupon, the code, when executed by at least one processor, causes the at least one processor to implement the method of claim 1 .

4 . A non-transitory computer-readable medium having code stored thereupon, the code, when executed by at least one processor, causes the at least one processor to implement the method of claim 2 .

5 . A wireless communication method, comprising:

receiving, by a wireless communication device from a wireless communication node, an authentication instruction message comprising a preamble sequence, an instruction code, an identification related to the wireless communication device, and an identification of the wireless communication node, that are arranged in above order;

determining, by the wireless communication device, that the identification of the wireless communication device contained in the authentication instruction message matches an identification stored by the wireless communication device; and

sending, by the wireless communication device to the wireless communication node, a response message acknowledging the authentication instruction message.

6 . The wireless communication method of claim 5 , further comprising:

sending, by the wireless communication device, a response message acknowledging the authentication instruction message, wherein the wireless communication node determines that the wireless communication device is authenticated in response to determining that the response message indicates that the identification of the wireless communication node has been received correctly.

7 . A non-transitory computer-readable medium having code stored thereupon, the code, when executed by at least one processor, causes the at least one processor to implement the method of claim 5 .

8 . A non-transitory computer-readable medium having code stored thereupon, the code, when executed by at least one processor, causes the at least one processor to implement the method of claim 6 .

9 . A wireless communication node, comprising:

at least one processor configured to:

determine an identification related to a wireless communication device; and

send, via a transmitter to the wireless communication device, an authentication instruction message,

wherein the authentication instruction message comprises a preamble sequence, an instruction code, the identification related to the wireless communication device, and an identification of the wireless communication node, that are arranged in above order.

10 . The wireless communication node of claim 9 , wherein the at least one processor is configured to:

receive, via a receiver, a response message acknowledging the authentication instruction message; and

determine that the wireless communication device is authenticated in response to determining that the response message indicates that the identification of the wireless communication node has been received correctly.

11 . A wireless communication device, comprising:

at least one processor configured to:

receive, via a transceiver from a wireless communication node, an authentication instruction message comprising a preamble sequence, an instruction code, an identification related to the wireless communication device, and an identification of the wireless communication node, that are arranged in above order;

determine that the identification of the wireless communication device contained in the authentication instruction message matches an identification stored by the wireless communication device; and

send, via the transceiver to the wireless communication node, a response message acknowledging the authentication instruction message.

12 . The wireless communication device of claim 11 , wherein the at least one processor is configured to:

send, via the transceiver, a response message acknowledging the authentication instruction message, wherein the wireless communication node determines that the wireless communication device is authenticated in response to determining that the response message indicates that the identification of the wireless communication node has been received correctly.
