[0041] In order to facilitate understanding of the embodiments of the present application, the following contents are first described.

[0042] Backscatter Communication (BSC) refers to a type of passive IoT device that uses radio frequency signals from other devices or the environment to modulate signals and transmit information. The basic building blocks and main functions of a backscatter communication transmitter include:

[0043] -Antenna unit: used to receive RF signals and control commands, and also used to send modulated backscattered signals.

[0044] Energy harvesting module or power supply module: This module is used by the backscatter communication device to harvest RF energy or other energy sources, including but not limited to solar energy, kinetic energy, mechanical energy, and thermal energy. In addition to the energy harvesting module, a battery power supply module may also be included, making the backscatter communication device semi-passive. The energy harvesting module or power supply module provides power to all other modules in the device.

[0045] -Microcontroller: includes control of baseband signal processing, energy storage or data scheduling status, switch switching, system synchronization, etc.

[0046] -Signal receiving module: used to demodulate control commands or data sent by the backscatter communication receiving end or other network nodes.

[0047] - Coding and modulation module: performs channel coding and signal modulation under the control of the controller, and realizes modulation by selecting different load impedances under the control of the controller through the selection switch.

[0048] -Memory or sensor module: used to store device identification information, location information or sensor data, etc.

[0049] In addition to the typical components mentioned above, future backscatter communication transmitters can also integrate tunnel diode amplifier modules, low-noise amplifier modules, etc. to improve the receiving sensitivity and transmission power of the transmitter.

[0050] Optionally, the basic building blocks and main functions of the backscatter communication receiving end include:

[0051] -Antenna unit: used to receive the modulated backscattered signal.

[0052] - Backscatter signal detection module: used to detect the backscatter signal sent by the backscatter communication transmitter, including but not limited to amplitude shift keying (ASK) detection, phase shift keying (PSK) detection, frequency shift keying (FSK) detection or quadrature amplitude modulation (QAM) detection, etc.

[0053] -Demodulation and decoding module: demodulates and decodes the detected signal to restore the original information stream.

[0054] Backscatter communication equipment controls the reflection coefficient Γ of the modulation circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal to achieve signal modulation. The reflection coefficient Γ can be expressed as:

[0055] Where Z0 is the antenna characteristic impedance; Z1 is the load impedance; j represents a complex number, θ T Indicates the phase. Assume that the incident signal is represented by S in (t), the output signal is Therefore, by properly controlling the reflection coefficient, corresponding amplitude modulation, frequency modulation, or phase modulation can be achieved. Based on this, backscatter communication devices can be tags in traditional radio frequency identification (RFID) or passive or semi-passive Internet of Things (IoT) devices. Here, backscatter communication devices are collectively referred to as BSC devices.

[0056] In one implementation, tags can be categorized into the following types based on their capabilities and source:

[0057] -C1 / C2 tags: Passive tags, which receive energy from electromagnetic waves sent by RFID readers and send data through backscatter communication.

[0058] -C3 tag: A semi-passive tag uses its own battery and other energy sources only for the circuitry within the RFID tag. It does not actively send data signals. It can only send data via backscatter communication after being activated by electromagnetic waves sent by the RFID reader.

[0059] -C4 tag: Active tag, which actively sends data by relying on its own battery or other energy source.

[0060] In another implementation, tags can be divided into:

[0061] Device A: This tag is passive and has no energy storage capacitor or battery. It relies on radio frequency (RF) signals for power. The received RF signal is the power signal for the rectifier. It does not have carrier generation capability and relies on RF as the RF carrier for backscatter communication transmission, thus minimizing power consumption.

[0062] Device B: This tag is semi-passive and has a storage capacitor / battery. It relies on non-RF signals for power. It may also have a power amplifier (PA) / low-noise amplifier (LNA) or other active components. It does not have carrier generation capability and relies on RF as the radio frequency carrier for backscatter communication transmission. Its power consumption is relatively low.

[0063] -Device C: This tag is an active tag with an energy storage capacitor / battery. It relies on non-RF signals for power supply and has carrier generation capability. It consumes the most power.

[0064] Optionally, the backscatter-based communication architecture may include at least the following modes:

[0065] (1) Topology 1: As shown in Figure 1A, the base station in Topology 1 is both a radio frequency source or transmitter and a receiver, so Topology 1 is a monostatic backscatter communication system (MBCS) architecture. A traditional RFID system is a typical MBCS, which includes ambient IoT devices (such as tags) and readers (such as base stations). Tags communicate directly with readers, and readers may have functional modules with a frequency division duplexing (FDD) architecture. In Topology 1, the transmitter of control signaling and the receiver of backscatter signals are the same device, while the transmitter of the RF carrier source can be the same device as the aforementioned device or a separate device.

[0066] (2) Topology 2: As shown in Figure 1B, in Topology 2, an ambient IoT device (e.g., a tag) receives control signaling and carrier signals from an intermediate node. The control signaling can be instructed by a network device (e.g., a base station gNB) through an intermediate node. The intermediate node can be a user equipment (UE), a repeater, an IAB node, etc. The intermediate node can also act as a relay to forward IoT data to the gNB.

[0067] (3) Topology 3: Topology 3 involves a bistatic backscatter communications system (BBCS), in which the RF source, BSC transmitting device, and BSC receiving device are separate. In Topology 3, the ambient IoT device (such as a tag) sends IoT data / uplink signaling to the base station and receives data / signaling from the auxiliary node, as shown in Figure 1C. Alternatively, the ambient IoT device (such as a tag) sends IoT data / uplink signaling to the auxiliary node and receives data / signaling from the base station, as shown in Figure 1D. The base station and the auxiliary node communicate through the Uu port. The auxiliary node can be a UE, repeater, IAB, etc.

[0068] (4) Topology 4: As shown in Figure 1E, in Topology 4, the UE acts as a reader to communicate with the tag. This architecture also belongs to the monostatic backscatter communication architecture, but the difference is that the reader is the UE, not the base station.

[0069] To better adapt to changes in wireless transmission channels, the communication system needs to adaptively change its transmission parameters, such as coding and modulation parameters, transmit power, and channel frequency, to better adapt to the wireless channel. Optionally, link adaptation may include at least the following:

[0070] (1) Adaptive transmission of modulation and coding, that is, adjusting the coding method, code rate, modulation method, modulation order, etc. according to the changes in the channel: when the channel quality is good, the coding rate and modulation order (level) are increased; when the channel quality is poor, the coding rate and modulation order (level) are reduced.

[0071] (2) Power control: When the channel quality is good, the transmit power is reduced to save power and interference; when the channel quality is poor, the transmit power is increased to ensure transmission reliability.

[0072] (3) Hybrid automatic transmission, that is, by adjusting the data redundancy information, the retransmission / combining gain is obtained at the receiving end, achieving accurate and fast adaptation to the small dynamic range of the channel.

[0073] (4) Channel selective scheduling, that is, selecting time-frequency resources with good channel conditions for data transmission based on the results of wireless channel measurement.

[0074] (5) Adjust the signal waveform, that is, determine the transmission signal waveform based on the results of channel measurement. For example, when the channel is not good, a low-power transmission waveform is selected; when the channel conditions are good, a transmission waveform with higher spectral efficiency is selected.

[0075] Optionally, the solution in this application can be applied to LTE systems, 5G NR systems and NR evolution systems, such as 6G systems and 6G evolution systems, as well as IEEE 802.11 systems (such as WiFi systems), Bluetooth systems, LoRa systems, Zigbee systems, wireless optical communication systems, low-power communication systems, backscatter communication systems, etc.

Therefore, by reasonably configuring or indicating the signal parameters of the second signal, link adaptation (including but not limited to MCS, transmission power, reflection coefficient, time-frequency domain resources, signal waveform, etc.) between the second device and the third device can be achieved, thereby realizing flexible link adaptive adjustment of multi-node backscatter communication (such as dual-base backscatter communication).

[0276] Example 1

[0277] In the first embodiment, the correlation relationship among the first signal, the second signal and the third signal in this solution is described according to different scenario requirements.

[0278] Scenario 1: The third signal is the radio frequency carrier signal of the first signal, and the third signal is the radio frequency carrier signal of the first signal.

[0279] In this scenario, both the second signal and the first signal are backscatter modulated signals generated based on a third signal. The third signal is the RF carrier signal of the second and first signals. The first signal is used by the first device to determine the signal parameters of the second signal and indicate them to the second device. In terms of time-frequency resources, the first signal precedes the second signal in the time domain, and the frequency domain of the first signal and the frequency domain of the second signal are in the same resource set. Figure 5A shows an example of the time-frequency domain resources of the first and second signals. The first signal #n and the second signal #n used to determine the signal parameters of the second signal #n are in the same resource set #n. In the time domain, the time interval between the second signal and the first signal is x. The time unit can be a frame, subframe, time slot, symbol, etc. The size of x can be specified by the protocol or configured by the network and can be a time window. The first signal #n and the second signal #n are within the coherence time or within a time window specified by the protocol. The time interval between the first signal #n and the first signal #(n+1) is y. The time unit can be a frame, subframe, time slot, symbol, etc. The size of y can be specified by the protocol or configured by the network and can be a time window. In the frequency domain, the first signal #n and the second signal #n are also in the same resource set, where the frequency domain resources of the first signal #n can be a comb structure in the frequency domain of the second signal #n, and the signal of the first signal #n after frequency domain interpolation is in the coherent bandwidth with the second signal #n (that is, the bandwidth spanned by the first signal and the signal bandwidth itself are still in the coherent bandwidth, otherwise the channel response obtained by the difference of the first signal will not be used for subsequent data transmission), or within the frequency domain bandwidth specified by the protocol, that is, the third device can estimate the channel parameters of the second signal #n based on the frequency domain resources of the first signal #n.

[0280] Furthermore, the third signal #2n associated with the first signal #n is also in the same resource set, and the third signal #(2n+1) associated with the second signal #n is also in the same resource set.

[0281] Scenario 2: The third signal is a reference signal for the second signal.

[0282] As shown in Figure 5B, when the third signal #n is a reference signal used to determine the second signal #n, the first signal #n and the third signal #n have exactly the same frequency domain resources or characteristics. The time interval between the third signal #n and the first signal #n is k, or the time interval between the third signal #n and the start of the first signal is z. The time unit can be a frame, subframe, time slot, symbol, etc. The size of z and k can be specified by the protocol or configured by the network and can be a time window. The third signal #n, the first signal #n, and the second signal #n are within the coherence time or within the time window specified by the protocol. The time-frequency domain resource relationship between the first signal #n and the second signal #n can be as described in Scenario 1 above and will not be repeated here.

[0283] Scenario 3: The third signal is a control signal of the second signal, or the third signal is a control signal of the first signal.

[0284] In another scenario, the third signal #n is a control signal for the second signal #n or the first signal #n. As shown in Figure 5C, the time-frequency domain relationship between the first signal #n and the second signal #n is as described above and will not be repeated. At this time, the frequency domain resources of the third signal #n and the frequency domain resources of the first signal #n or the second signal #n can be in the same resource set or different resource sets. In the time domain, the time domain resources of the third signal #n and the time domain resources of the first signal #n or the second signal #n are within the coherent time, or within the time window specified by the protocol. The time-frequency domain resource relationship between the first signal #n and the second signal #n can be as described in scenario 1 above and will not be repeated.
