In order to facilitate understanding of the embodiments of the present application, the following is first described.
Backscatter communication (Backscatter Communication, BSC), which means that a backscatter communication device uses radio frequency signals in other devices or environments to modulate signals to transmit its own information, is a relatively typical passive internet of things device. The basic constitution module of the back scattering communication transmitting end comprises the following main functions:
-an antenna unit: for receiving radio frequency signals, control commands, and for transmitting modulated backscatter signals.
-An energy harvesting module or an energy supply module: the module is used for radio frequency energy harvesting by the backscatter communications device, or other energy harvesting, including but not limited to solar energy, kinetic energy, mechanical energy, thermal energy, etc. In addition to the energy harvesting module, a battery powered module may be included, where the backscatter communications device is a semi-passive device. The energy harvesting module or the energy supply module supplies power to all other modules in the device.
-A microcontroller: including control of baseband signal processing, energy storage or data scheduling states, switching, system synchronization, etc.
-A signal receiving module: for demodulating control commands or data and the like sent by a backscatter communication receiver or other network node.
-A channel coding and modulation module: channel coding and signal modulation are performed under the control of a controller, and modulation is realized by selecting different load impedances through a selection switch under the control of the controller.
-A memory or sensing module: for storing identification ID information, location information, or sensor data of the device, etc.
In addition to the above-described typical constituent modules, the future backscatter communication transmitter may also incorporate a tunnel diode amplifier module, a low noise amplifier module, or the like for improving the reception sensitivity and transmission power of the transmitter.
Optionally, the basic constituent modules of the backscatter communication receiver, i.e. the reader, include:
-an antenna unit: for receiving the modulated backscatter signal.
-A backscatter signal detection module: for detecting the backscatter signal transmitted by the backscatter communication transmitter, including, but not limited to, amplitude shift keying (Amplitude SHIFT KEYING, ASK) detection, phase-shift keying (Phase-SHIFT KEYING, PSK) detection, frequency shift keying (Frequency-SHIFT KEYING, FSK) detection, quadrature Amplitude modulation (Quadrature Amplitude Modulation, QAM) detection, etc.
-A demodulation and decoding module: the detected signal is demodulated and decoded to recover the original information stream.
The backscatter communication device 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, effecting modulation of the signal. Wherein the reflection coefficient of the signal can be characterized as:
Where Z 0 is the antenna characteristic impedance, Z 1 is the load impedance, j represents the complex number, and θ T represents the phase. Assuming that the incident signal is S in (t), the output signal is Thus, by reasonably controlling the reflection coefficient, a corresponding amplitude modulation, frequency modulation or phase modulation can be achieved. Based on this, the backscatter communication device may be a Tag in a conventional radio frequency identification (Radio Frequency Identification, RFID) or a Passive or Semi-Passive internet of things (IoT). For convenience, referred to herein as BSC devices.
Fig. 1A shows a schematic diagram of a single-base backscatter communication system (Monostatic Backscatter Communication System, MBCSs) to which embodiments of the present application are applicable. The MBCS system includes a BSC transmitting device (e.g., tag) and a Reader including an RF radio frequency source and a BSC receiving device, the RF radio frequency source being configured to generate RF radio frequency signals to power the BSC transmitting device/Tag. The BSC transmitting device back scatters the modulated RF signal, and the BSC receiving device in the Reader receives the back scattered signal and then demodulates the signal. The RF source and BSC receiving device are in the same device, such as a Reader herein, and thus become a single-station backscatter communication system. MBCS systems are typically used for short-range backscatter communications, such as conventional RFID applications, because the RF radio frequency signals transmitted from the BSC transmitting device experience a double near-far effect due to the signal attenuation of the round-trip signals, and thus the energy attenuation of the signals is large.
Fig. 1B shows a schematic diagram of a bistatic backscatter communication system (Bistatic Backscatter Communication Systems, BBCSs) to which embodiments of the present application are applicable. Unlike the monostatic backscatter communication systems (Monostatic Backscatter Communication System, MBCSs), the RF source, BSC transmitting device, and BSC receiving device in the BBCS system are separate, so that the problem of large round trip signal attenuation can be avoided. In addition, the performance of BBCS communication systems may be further improved by the proper placement of the RF sources. Notably, the ambient backscatter communication system ABCSs is also one of a bistatic backscatter communication system, but unlike the radio frequency source in the BBCS system, which is a dedicated signal radio frequency source, the radio frequency source in the ABCS system can be a radio frequency source in a usable environment, such as: television towers, cellular base stations, wiFi signals, bluetooth signals, etc.
For coverage in backscatter communication, forward and reverse coverage of backscatter communication face a large technical challenge due to the influence of transmission power of network nodes, two-way link attenuation, energy storage efficiency and energy storage capacity of energy storage circuits, receiving sensitivity of backscatter communication equipment, receiving-transmitting antenna gain, signal interference and the like. 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 about 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 and an integrated low power amplifier are all effective ways to improve backscatter communications coverage. In addition, the energy of the radio frequency signal can be concentrated by using the MIMO beamforming technology, and the problem of backscatter communication coverage can be effectively improved by combining an energy acquisition circuit with high energy conversion efficiency. Under the constraint condition that the energy collection of the back scattering communication equipment is maximized, the 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 and the transmitting end of the passive beam forming in the back scattering equipment.
In a system requiring radio frequency power supply such as backscatter communication (for example, a backscatter communication device), since 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 restricting the transmission distance of the backscatter communication. Because the attenuation of uplink and downlink transmission signals is related to the distance between nodes, in the following behavior example, when a backscattering communication device which is closer to energy supply devices such as a base station is harvested to more energy, less energy is needed to meet the uplink transmission requirement; conversely, a backscatter communication device farther from the base station requires more energy to meet the uplink transmission demand while harvesting less energy, a phenomenon known as the double near-far effect. The double near-far effect problem can be solved based on energy beam forming, and more energy is harvested by a far user by controlling the width and the power of the beam.
In addition to backscatter communications, some terminal devices that are not battery powered or 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.
In the conventional beam forming (beamforming) in 5G NR, the phase of each element in an antenna array is adjusted to generate a beam with directivity, so as to improve transmission coverage, improve edge throughput, suppress interference, and the like. In addition, if the characteristics of high space freedom degree of the channel are fully utilized to realize multi-stream transmission, the system capacity and the user rate can be improved. The beam alignment of the receiving and transmitting end is a precondition for realizing the multi-antenna reliability transmission, and comprises the steps of beam selection, beam measurement, beam reporting and the like. The existing beam transmission is mainly designed for communication service, so that parameters such as Layer 1reference signal received power (Layer 1Reference Signal Received Power,L1-RSRP) of reference signals, layer 1 signal-to-interference-plus-noise ratio (Layer 1Signal to Interference plus Noise Ratio,L1-SINR) and the like are used as signal quality evaluation criteria for beam measurement and beam selection in the beam measurement process. And the energy supply equipment can also adopt the directional beam to carry out beamforming energy transmission, so that the problems of energy conversion efficiency and near-far effect of the communication equipment to be wirelessly supplied with energy are improved. However, unlike the existing NR system, which uses parameters such as L1-RSRP, L1-SINR, etc. of communication signals as signal quality evaluation criteria for beam measurement and beam selection, energy beams based on energy transmission do not need to consider that the signal quality of the selected beam is optimal, but only the selected energy-shaped beam needs to be considered to provide the strongest power, including the sum of the total power from the useful signal, the interfering signal, and the noise. Therefore, for the beam of energy beam measurement and energy beam selection, new beam measurement and beam selection criteria, training process, signaling flow, etc. need to be designed so that the trained energy beam can achieve the optimal energy supply effect.
The embodiment of the application can be applied to LTE systems, 5G NR systems and NR evolution systems, such as 6G systems, and a plurality of wireless communication systems which are applicable to energy beam forming and the like, such as IEEE 802.11, wireless optical communication, passive Internet of things, back scattering communication and the like.

Example 1
In the first embodiment, as shown in fig. 4, taking the first device as a base station device and the second device as a UE requiring radio frequency power supply or a backscatter communication BSC device as an example, the downlink energy shaping beam (i.e. the first beam) training/processing procedure is described, where the base station transmits a reference signal and the second device performs measurement. The embodiment is applicable to a device to be powered, such as a device with measurement capability, for example, a passive or semi-passive UE, or a backscatter communication BSC device with relatively high capability. The specific beam training/processing procedure includes:
s1: the base station configures measurement resources and reporting resources of UE or BSC equipment;
S2: the base station transmits a first signal at a different Tx beam;
for example, the first signal may be an SSB, CSI-RS, TRS, or other L1 signal, etc.
S3: the UE or BSC equipment measures the measured value of the first signal on the corresponding measured resource and reports the beam measurement report on the configured reporting resource;
Optionally, the beam measurement report includes at least: the type of the first signal, the identity of the first signal, and the measured value of the first signal.
Alternatively, the measured value of the first signal may be the RSSI of the first signal, or the difference between the RSSI of the first signal and the target RSSI.
S4: the UE or BSC equipment reports beam related information associated with the first signal meeting the target condition;
for example, reporting may be performed in an explicit or implicit manner.
S5: the base station determines parameters of Tx beam (namely downlink energy forming beam) according to a beam measurement report and/or beam related information reported by UE or BSC equipment;
s6: alternatively, if the UE or BSC device itself has a transceiving beam, the base station may configure or indicate the TCI state of the UE or BSC device.
Example two
In the second embodiment, as shown in fig. 5, taking the first device as a base station device and the second device as a UE that needs radio frequency energy supply as an example, the downlink energy shaping beam (i.e. the first beam) training/processing process is described, where the second device actively transmits the reference signal. The embodiment is suitable for the architecture that the UE to be powered has the capability of sending the reference signal and is based on TDD frequency band networking. The specific beam training/processing procedure includes:
S1: the base station configures time-frequency resources for the UE to send the first signal;
s2: the UE sends a first signal, and the base station receives the first signal sent by the UE at different Rx beams;
for example, the first signal may be an SRS signal, other L1 signals, and the like.
S3: the base station measures the RSSI of the first signal on the corresponding time-frequency resource;
S4: the base station determines parameters of Tx beam (namely downlink energy forming beam) based on beam correspondence (beam consistency) according to the self measurement result;
s5: alternatively, if the UE itself has a transceiving beam, the base station may configure or indicate the TCI state of the UE.
Example III
In the third embodiment, as shown in fig. 6, taking the first device as a base station device and the second device as a BSC device that needs radio frequency energy supply as an example, the downlink energy shaping beam (i.e. the first beam) training/processing procedure is described, where the second device sends a backscattered reference signal. The embodiment is suitable for the architecture that the UE to be powered does not have the back scattering communication equipment for actively generating the carrier wave and is based on the TDD frequency band networking. Since the BSC device needs other devices to provide a radio frequency carrier to the BSC device before sending the signal, and then modulates the signal based on the radio frequency carrier to generate a backscatter signal, a specific beam training/processing procedure includes:
S1: the base station configures time-frequency resources and/or reflection coefficients of the BSC equipment for sending the first signals;
S2: the base station transmits a first signal or a radio frequency carrier signal;
For example, if the base station transmits the first signal, the BSC apparatus reflects the first signal with the indicated reflection coefficient, does not make any modulation, or makes all 1 modulation.
For example, if the base station transmits a radio frequency carrier signal, the BSC apparatus modulates the radio frequency carrier signal with the configured time-frequency resource, and generates a first signal.
S3: the base station measures the RSSI of the first signal on the corresponding time-frequency resource;
S4: the base station determines parameters of Tx beam (namely downlink energy forming beam) based on beam correspondence according to the self measurement result;
s5: alternatively, if the BSC device itself has a transceiving beam, the base station may configure or indicate the TCI state of the BSC device.
Example IV
In the fourth embodiment, taking an example that the UE or the BSC device is at the cell edge and is interfered by other cells, the difference between the present scheme based on RSSI as the beam quality evaluation criterion and the present NR based on RSRP or SINR as the beam quality evaluation criterion is described. As shown in fig. 7A and 7B, fig. 7A is a beam pattern obtained based on the L1-RSSI signal estimation criterion, and fig. 7B is a beam pattern obtained based on the L1-RSRP or L1-SINR signal estimation criterion, where the UE is at the cell edge and receives radio frequency signal energy transmitted from other cell base stations or UEs in addition to radio frequency signal energy provided from the own serving cell base station. Since different UEs or BSC devices are interfered to different degrees, it is highly likely that the beam trained based on the RSSI signal evaluation criterion is different from the beam trained based on the SINR/RSRP signal evaluation criterion, including the direction of the beam, the bandwidth of the beam, the power of the beam, and so on. For the UE or BSC device which only needs to realize high efficiency of radio frequency energy conversion, it is desirable that the sum of the radio frequency signal energy provided by the base station of the serving cell and the interference energy from each cell is maximum, and the signal quality such as SNR or SINR of the radio frequency signal provided by the base station of the serving cell is not concerned. Therefore, the RSSI-based beam training evaluation criteria are more accurate for energy shaping beams.
