Abstract
This application discloses a method and apparatus for backscatter signal transmission, a communication device, and a readable storage medium. The method includes: determining, by a tag based on first information, a parameter related to transmission of a backscatter signal; where the first information includes at least one of the following: a first value, where the first value is used to indicate a random number generated by the tag; a second value, where the second value is used to indicate a counter value of the tag; a third value, where the third value is used to indicate a counter step of the tag.
Claims20
A method for backscatter signal transmission, comprising:
- determining, by a tag based on first information, a parameter related to transmission of a backscatter signal;
- wherein
- the first information comprises at least one of the following:
- a first value, wherein the first value is used to indicate a random number generated by the tag;
- a second value, wherein the second value is used to indicate a counter value of the tag;
- or
- a third value, wherein the third value is used to indicate a counter step of the tag,
- wherein the determining, by a tag based on first information, a parameter related to transmission of a backscatter signal comprises:
- when the first information comprises the third value and the third value is greater than 1, determining, by the tag based on the first information, the parameter related to the transmission of the backscatter signal,
- wherein the method further comprises at least one of the following:
- when the counter value of the tag is any one of 0 to a fourth value, performing, by the tag, the transmission of the backscatter signal, wherein the fourth value is equal to the third value minus 1, and the third value is greater than 1, and
- receiving, by the tag, third information, wherein the third information is used to indicate the tag to subtract the third value from the counter value.
A method for backscatter signal transmission, comprising:
- determining, by a reader/writer based on first information, a parameter related to transmission of a backscatter signal;
- and
- performing, by the reader/writer, detection for the backscatter signal based on the parameter, wherein
- the first information comprises at least one of the following:
- a first value, wherein the first value is used to indicate a random number generated by a tag;
- a second value, wherein the second value is used to indicate a counter value of the tag;
- or
- a third value, wherein the third value is used to indicate a counter step of the tag,
- wherein the determining, by a reader/writer based on first information, a parameter related to transmission of a backscatter signal comprises:
- when the first information comprises the third value and the third value is greater than 1, determining, by the reader/writer based on the first information, the parameter related to the transmission of the backscatter signal,
- wherein the method further comprises at least one of the following:
- determining, by the reader/writer, whether the counter value of the tag is any one of 0 to a fourth value, wherein when the counter value of the tag is any one of 0 to a fourth value, the reader/writer performs the detection for the backscatter signal, wherein the fourth value is equal to the third value minus 1, and the third value is greater than 1, and
- transmitting, by the reader/writer, third information, wherein the third information is used to indicate the tag to subtract the third value from the counter value.
A tag comprising a processor, a memory, and a program or an instruction stored in the memory and capable of running on the processor, wherein the program or the instruction, when executed by the processor, implements the steps of:
- determining, based on first information, a parameter related to transmission of a backscatter signal;
- wherein
- the first information comprises at least one of the following:
- a first value, wherein the first value is used to indicate a random number generated by the tag;
- a second value, wherein the second value is used to indicate a counter value of the tag;
- or
- a third value, wherein the third value is used to indicate a counter step of the tag,
- wherein the determining, based on first information, a parameter related to transmission of a backscatter signal comprises:
- when the first information comprises the third value and the third value is greater than 1, determining, based on the first information, the parameter related to the transmission of the backscatter signal,
- wherein the method further comprises at least one of the following:
- when the counter value of the tag is any one of 0 to a fourth value, performing the transmission of the backscatter signal, wherein the fourth value is equal to the third value minus 1, and the third value is greater than 1, and
- receiving third information, wherein the third information is used to indicate the tag to subtract the third value from the counter value.
