For ease of understanding, some of the following descriptions are directed to embodiments of the present application:

1. Backscatter communication.

Backscatter communication refers to that backscatter communication devices use radio frequency signals in other devices or environments to perform signal modulation to transmit their own information, and is a typical passive internet of things device.

2. A monostatic backscatter communication system (Monostatic Backscatter Communication System, MBCSs).

As shown in fig. 2, MBCS, such as a conventional radio frequency identification (Radio Frequency Identification, RFID) system is a typical MBCS, and the system includes a BSC transmitting end (such as a Tag) and a Reader. The reader/writer comprises an RF source and a BSC receiver, wherein the RF source is used for generating an RF signal so as to power the BSC transmitter/Tag. The BSC transmitting end receives the back scattered signal by back scattering the modulated RF signal, and then carries out signal demodulation. The RF source and BSC receiver are in the same device, such as the Reader herein, and thus become a single-station backscatter communication system. In MBCSs systems, MBCS systems are typically used for short-range backscatter communications, such as conventional RFID applications, because the RF signal sent from the BSC's sender experiences double near-far effects due to signal attenuation of the round-trip signal, and thus the energy attenuation of the signal is large.

3. A bistatic backscatter communication system (Bistatic Backscatter Communication Systems, BBCSs).

Unlike MBCS, the RF radio frequency source, BSC transmitting device, and BSC receiving device in BBCS are separate, as shown in fig. 3, which is a schematic diagram of the BBCS system. Thus BBCS avoids the problem of large round trip signal attenuation, and further improves the performance of BBCS communications systems by reasonable placement of RF sources. Notably, the ambient backscatter communication system (Ambient Backscatter Communications Systems, ABCSs) is also one of the bistatic backscatter communication, but the radio frequency source in the ABCS system may be a dedicated signal radio frequency source with the radio frequency source in the BBCS system, such as: television towers, cellular base stations, wiFi signals, bluetooth signals, etc.

4. Coverage in backscatter communications.

Limited by the effects of network node transmit power, two-way link attenuation, tank circuit energy storage efficiency and capacity, backscatter communications device receive sensitivity, transceiver antenna gain, and signal interference, both forward and reverse coverage of backscatter communications present significant technical challenges. In particular, for the forward link from the network node to the backscatter communications device, the signal strength or sensitivity of the backscatter communications device to receive radio frequency signals for powering is approximately-20 dBm, whereas the receiver sensitivity of a conventional terminal device is approximately-100 dBm, since the drive energy harvesting circuit requires several to tens of uW of energy to operate. If the backscatter communication device is energy storage capable, its reception sensitivity for receiving radio frequency signals for powering may relax to-30 dBm. In addition, considering the characteristics of the energy harvesting circuit, that is, the lower the power of the input signal, the lower the energy conversion efficiency, so that when the power of the input radio frequency signal is lower than-23 dBm, the energy harvesting circuit is difficult to efficiently harvest the signal and rectify the signal into a usable direct current voltage. On the other hand, in the reverse link from the backscatter communication device to the network node, the signal strength of the backscatter is 3dB to 5dB lower than the signal strength of the incident energizing signal, since part of the signal energy is used to energize. In addition, the antenna gain of low hardware cost backscatter communications devices is typically not too great, on the order of 0dBi to 2dBi.

The use of a split architecture (i.e., a bistatic backscatter communication system) and an integrated low power amplifier are both effective ways to improve backscatter communication coverage. In addition, by using the MIMO beamforming technology, the energy of the radio frequency signal can be concentrated, and the problem of backscatter communication coverage can be effectively improved by combining with an energy harvesting circuit with high energy conversion efficiency. Under the constraint condition that energy collection maximization of the back scattering equipment is met, forward coverage can be effectively enhanced by combining the mixed beam forming of the radio frequency source and the combined beam forming scheme of the receiving end of passive beam forming in the back scattering equipment.

In the related art, beam transmission is mainly designed for communication services, so in the beam measurement process, parameters such as Layer 1reference signal received power (Layer 1reference signal received power,L1-RSRP) of a reference signal, layer 1signal-to-noise AND INTERFERENCE ratio (L1-SINR) and the like are used as signal quality evaluation criteria for beam measurement and beam selection. However, in a system requiring radio frequency energy such as backscatter communication, because the backscatter communication device needs to rely on radio frequency signal power supply of other devices to perform data transmission, and is affected by the receiving sensitivity of the backscatter communication device, the sensitivity of the backscatter communication device for receiving the power supply signal is about-20 dBm to-30 dBm, and the sensitivity for receiving the communication data is about-50 dBm to-60 dBm, the radio frequency power supply becomes a bottleneck for limiting the transmission distance of the backscatter communication. As with directional beam-based transmission in NR, the energy supply device may also employ directional beams for beam energy transfer, thereby improving the energy conversion efficiency of the backscatter communication device and the problem of limited radio frequency energy supply coverage. However, unlike the NR system, which uses parameters such as L1-RSRP and L1-SINR of a communication signal as signal quality evaluation criteria for beam measurement and beam selection, an energy beam based on energy transmission does not need to consider that the signal quality of the selected beam is optimal, but only the selected energy beam is considered to provide the most powerful energy supply. Furthermore, due to the limitation of energy storage capability and energy conversion efficiency, the uplink of the UE device based on radio frequency energy collection also has a problem of communication coverage. In order to increase the coverage distance, the receiving end can also use a beamforming technology to obtain beamforming gain, so as to increase communication coverage.

The beam training method in the related art is mostly aimed at beam training under a single base architecture, that is, the device that provides the downlink transmission beam and the device that provides the uplink reception beam are the same device, such as a base station device. However, for a dual-base architecture, the device that provides the downlink transmit beam, the device that provides the uplink receive beam, and the device that receives the downlink transmit beam are different devices, thereby creating a beam training problem under the cascaded channel. Taking fig. 4 as an example, the device providing the downlink energy transmission beam (i.e., the third device) is a UE, the device providing the uplink reception beam (i.e., the first device) is a base station device, and the device receiving the downlink transmission beam (i.e., the second device) is a UE device or a BSC device that needs to be powered, so that the first device-the second device-the third device form a cascade link. Since the first device and the third device are not the same device, the first device and the third device need to perform signaling interaction to finally determine the transmit-receive beam with the best beamforming gain. For this purpose, the signal measurement processing method in the cascade link of the application is proposed. It is worth noting that in addition to backscatter communications, some terminal devices that are not battery powered or that are costly to replace batteries may also be powered based on radio frequency energy. Such devices may harvest and store energy based on wireless radio frequency energy of the network node and autonomously generate carrier signals for communication transmissions using the harvested energy. The signal measurement processing method in the cascade link of the application is also applicable to the scenario that the second device has the capability of autonomously generating the carrier.

The signal measurement processing method in the cascade link provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.
