  • Backscatter communication sending equipment is a passive communication equipment that can use other equipment or radio frequency signals in the environment for signal modulation to transmit its own information. Since the backscatter communication sending equipment is a passive device and can only work normally when the energy is sufficient to drive each circuit module inside it, the working state (or working mode) of the backscattering communication sending equipment can usually be divided into energy storage state and energy storage state. In the communication state, in the energy storage state, the backscatter communication sending device can collect ambient radio frequency energy to power the internal circuit, without transmitting and receiving uplink and downlink data or command transmission. In the communication state, the backscattering communication sending device can perform uplink and downlink Transmitting and receiving data or transmitting instructions, or storing energy simultaneously during the process of transmitting and receiving uplink and downlink data or transmitting instructions.

Therefore, for backscatter communication As for the communication receiving device, when communicating with the backscattering communication sending device, it needs to know when the backscattering communication sending device is in the energy storage state or when it is in the communication state, so that it can communicate with the backscattering communication device in the communication state.

  • the backscatter communication receiving device cannot know the energy storage or communication status of the backscattering communication sending device, which can easily causing status mismatch. For example, in the energy storage state, if the radio frequency source sends wake-up indication information to the backscatter communication sending device based on the radio frequency carrier signal, the backscatter communication sending device can determine whether to wake up by analyzing the statistical characteristics of the carrier signal. Wake up or continue to store energy.

  • the communication status of the receiving device does not match.
  • the radio frequency source and the backscatter communication sending device enter the communication state according to a fixed mode after the energy storage state, but because the backscatter communication receiving device does not know this configuration, it cannot know the configuration of the backscattering communication sending device.

In the case of status mismatch, the backscatter communication receiving equipment needs to continuously perform blind detection of synchronization signals and control commands, which can easily cause unnecessary blind detection or missed detection, as well as power consumption loss caused by detection.
