Abstract
A backscatter communication method and apparatus provides operation including: receiving a first excitation signal from a first device; determining a first resource based on a candidate resource; and sending a backscattered signal of the first excitation signal to a second device based on the first resource. This can reduce a probability of selecting a same resource as another device to some extent, so that a conflict is reduced, and an access success rate of a backscatter device can be improved.
Claims20
An apparatus comprising:
- at least one processor configured to execute instructions to cause the apparatus to at least be configured to:
- receive a first excitation signal from a first device;
- and
- send a backscattered signal of the first excitation signal to a second device based on a first frequency domain resource, wherein the first frequency domain resource is determined based on a first frequency offset step and a first factor;
- wherein the first frequency offset step is a default value or a preset value, the first factor is determined according to a rule that one of candidate factors is randomly selected as the first factor, or the rule is configured to enable different scatter devices to select different factors.
A method comprising:
- receiving a first excitation signal from a first device;
- and
- sending a backscattered signal of the first excitation signal to a second device based on a first frequency domain resource, wherein the first frequency domain resource is determined based on a first frequency offset step and a first factor;
- wherein the first frequency offset step is a default value or a preset value, the first factor is determined according to a rule that one of candidate factors is randomly selected as the first factor, or the rule is configured to enable different scatter devices to select different factors.
A non-transitory computer readable storage medium storing instructions that are executable by a computer, and the instructions comprise instructions for:
- receiving a first excitation signal from a first device;
- and
- sending a backscattered signal of the first excitation signal to a second device based on a first frequency domain resource, wherein the first frequency domain resource is determined based on a first frequency offset step and a first factor;
- wherein the first frequency offset step is a default value or a preset value, the first factor is determined according to a rule that one of candidate factors is randomly selected as the first factor, or the rule is configured to enable different scatter devices to select different factors.
