  • coverage of the FDD DL spectrum and the FDD UL spectrum can be achieved through a filter, so that there is no need to obtain the above-mentioned first information, and the FDD DL signal and the FDD UL signal can be directly received, thereby simplifying the operation difficulty.
  • Example 1 As shown in FIG7 , a tag has a filter.
  • the tag filter ranges from f1 to f2, representing a wideband filter.
  • DL commands are sent at frequency f3
  • UL commands are sent at frequency f4.
  • the frequency domain locations of f3 and f4 lie between f1 and f2, meaning the tag filter can include both DL and UL command spectra.

  • One approach is for the tag to continuously receive CWs when not communicating with the reader to conserve energy.

  • the simplest mapping is to associate DL CWs with DL commands, UL CWs with UL commands, or vice versa.
  • the tag uses the current filter position as the reference and determines the command position by offsetting it by 5MHz.
  • One embodiment is to determine the frequency domain position of the command through the mapping relationship between signal parameters and signals. Taking signal bandwidth as an example, the DL command signal bandwidth from the base station is in the MHz level, and the UL command signal bandwidth from the UE is in the KHz level.
  • the tag can determine whether to switch to filter1 or filter2 based on the current signal bandwidth.
  • One way is to determine it through blind detection, that is, after CW activates the AIoT device, the AIoT device selects (predefined) or is determined by the protocol to first try to receive the reader's downlink transmission, such as preamble, command, in the frequency domain range covered by Filter 1 or filter 2. If a valid transmission from the reader is detected, the AIoT device determines the frequency domain range for receiving the command; if no valid transmission from the reader is received within the first time after CW activation, the AIoT device switches to filter 2 or filter 1 to detect valid transmission from the reader.
  • the above-mentioned first time can be determined by protocol agreement, network side device configuration or based on a timer.
  • the timer is started.
  • a Filter detects the downlink transmission from the reader. If no valid transmission from the reader is received during the operation of the timer, it switches to another Filter to detect the downlink transmission from the reader.
  • Example 3 Feedback confirmation information, including two situations:
  • Confirm pre-switching feedback that is, the tag receives the switching instruction and sends an ACK to the reader before executing the switching instruction, including any of the following:
  • the switching command is sent by the base station or by the UE requesting the base station to switch from the FDD DL spectrum to the FDD UL spectrum.
  • the tag After receiving the switching command, the tag sends an ACK signal to the base station.
  • the switching command is sent by the UE or instructed by the network side device to be sent by the UE. It is necessary to switch from the FDD UL spectrum to the FDD DL spectrum. After receiving the switching command, the tag feeds back ACK to the UE.
  • the feedback time required for the above feedback can be predefined, specified by the protocol, instructed by the network-side device, and determined based on the device type. For example, passive devices have a longer feedback time, while active devices have a shorter feedback time; devices that can only communicate with backscatter have a longer feedback time, while devices that can autonomously generate UL signals have a shorter feedback time.
