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 monostatic backscatter communication system (Monostatic Backscatter Communication System, MBCSs) in accordance with the present application. 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) in accordance with the present application. 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.
Symbiotic scattering communication has the characteristics of reciprocal sharing of frequency spectrum and energy domain, and can effectively solve the problems of frequency spectrum and energy consumption faced in communication. The basic principle is that two types of systems exist in the system: the system comprises a main system and a secondary system, wherein the main system is a traditional communication system comprising an active transmitting unit, and the secondary system realizes low-power-consumption back-scattering transmission by utilizing radio frequency signals of the main system so as to share the frequency spectrum, energy, basic equipment resources and the like of the main system. While the secondary system obtains a low energy consumption transmission opportunity, the primary system is expected to improve the performance due to the multipath component received from the secondary system. Compared with the traditional cognitive radio technology, the main system and the auxiliary system in symbiotic scattering communication are hopeful to form a reciprocal relationship, but not an interference relationship, so that the spectrum resource utilization efficiency of the system can be greatly improved. In addition, unlike traditional backscatter communications (such as single-base backscatter communications, double-base backscatter communications, and ambient backscatter communications), the primary and secondary systems in symbiotic scatter communications cooperate with each other, and their receivers can employ joint detection to simultaneously recover signals transmitted by the primary and secondary systems, thereby achieving highly reliable backscatter communications transmissions.
The system models of symbiotic scatter communication can be divided into two categories: a split model and an integrated model. In the split model, as shown in fig. 2A, the primary and secondary systems each have a respective receiver, wherein the primary system transmitter (PRIMARY TRANSMITTER, PTx) transmits information to the primary system receiver (PRIMARY RECEIVER, PRx); and the secondary system transmitter (secondary transmitter, STx) transmits information to the secondary system receiver (secondary receiver, SRx) using an over-the-air modulation technique. In the integrated model, as shown in fig. 2B, the primary and secondary systems share the same integrated receiver (INTEGRATED RECEIVER, IRx) that needs to recover the transmitted signals from both the primary system transmitter PTx and the secondary system transmitter STx. The present application is mainly described on the basis of an integrated model, since the advantage of the deployment of the integrated model is greater.
Taking an integrated model as an example, the signal model and principle of the system will be briefly described below. The transmitted symbol period of PTx is denoted as T s, and its constellation point set is denoted asAs shown in fig. 3, the secondary system transmission symbol period is set to K times T s, i.e., T c=KTs. Assuming that the primary and secondary systems are strictly synchronized, one symbol of the secondary system corresponds to K symbols of the primary system. Considering the nth symbol of the secondary system, let s l (n), l=0, …, K-1 denote the first symbol sent by the primary system, the signal received by STx from the primary system is:
Where p represents the transmit power of PTx, h 1 and τ 1 represent the channel and propagation delay, respectively, of the forward link from PTx to STx, and f 0 represents the carrier frequency of the primary system.
Let h 0 denote the direct link channel from PTx to IRx and h 2 denote the backward link channel from STx to IRx. Assuming that the direct link from PTx to IRx has the same delay as the reflected link from PTx to STx to IRx, the baseband signal y l (n) received by IRx can be expressed as:
Wherein, Representing additive gaussian white noise. /(I)Representing received signals from a direct link,/>Representing the received signal from the reflective link, where b (n) is the baseband signal of STx, otherwise known as the backscatter baseband signal. The above-mentioned channels are called multiplicative multiple access channels, or concatenated channels, due to the multiplication of b (n) and s l (n) in the back-scattered link received signal.
The upper and lower limits of the achievable rates of the primary and secondary systems for the above-described system are shown below, respectively. When the primary system symbol s l (n) is perfectly demodulated, the secondary system can get its achievable rate upper bound. When K takes a larger value, the upper bound can be expressed as:
For the main system, s l (n) exists in the direct link and the reflection link, when s l (n) is decoded, the reflection link can be regarded as a slowly varying multipath channel for the direct link, so as to bring multipath effect to the transmission of the main system, and the up-to-date rate upper bound of the main system can be expressed as:
this achievable rate upper bound is achievable when b (n) can be perfectly demodulated. At this time, the primary system obtains performance gain, and the primary and secondary systems form a reciprocal symbiotic relationship. The receiver may demodulate b (n) in a variety of ways, such as a joint detection receiver, a semi-blind detection receiver, and a full-blind detection receiver, and the specific algorithm will not be described here.
In a system requiring radio frequency power supply, such as symbiotic back-scattering communication (for example), since the back-scattering 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 back-scattering communication device, the sensitivity of the back-scattering communication device for receiving the power supply signal is about-20 dBm to-30 dBm, and the sensitivity of the receiving communication data is about-50 dBm to-60 dBm, the radio frequency power supply becomes a bottleneck for limiting the transmission distance of the back-scattering 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 power 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.
As shown in fig. 4, in the symbiotic scattering communication system based on beam transmission, PTx and IRx in the conventional system improve coverage or reduce interference based on beam transmission, whereas in the backscatter communication cascade system consisting of PTx-STx-IRx, PTx improves energy conversion efficiency and near-far effect problem of the backscatter communication device by using directional beams to power and supply radio frequency carriers to the backscatter communication device, and IRx uses receiving beams to improve communication coverage and reduce interference of the STx-IRx. Further, based on the symbiotic communication of beam transmission, on one hand, the cascading links PTx-STx-Irx can provide beam gain through beam transmission, and provide multipath gain with larger energy for the direct links PTx-IRx, so that the performance gain of the main system is improved; on the other hand, the direct link PTx-IRx based on beam transmission can reduce the direct link interference influence on the cascade link PTx-STx-IRx, thereby improving the performance of the subsystem. For PTx-IRx links, it is desirable on the one hand that the beams of the present link can achieve a trade-off between stability and transmission performance, and that the beam selection is made according to this principle; on the other hand, it is desirable that the larger the multipath component provided by PTx-STx-IRx, the more obvious the multipath gain itself is obtained, and therefore the larger the communication energy between PTx-STx-IRx, the better, which is also one of the factors that PTx-STx-IRx needs to consider in making beam selection. For PTx-STx-IRx, however, it is desirable that PTx-IRx has less interference to its direct link on the one hand and better to reduce interference to its own system; on the other hand, it is desirable that the beam of the PTx-STx-IRx link itself be able to trade off between stability and transmission performance, which is also another factor that the direct link and the reflective link need to consider when making beam selection.
Therefore, for PTx, transmission beams (Tx beams) are required to be transmitted to two devices of IRx and STx, while IRx, reception beams (Rx beams) are required to be received to two devices of PTx and STx, corresponding beam training/processing methods, signal quality evaluation criteria, corresponding signaling flows such as beam measurement and beam reporting, and corresponding parameter configuration are required to be designed, so that the two Tx beams and the two Rx beams of IRx of the finally trained PTx are better overall, and the communication requirements of a main system and a secondary system are met.
The scheme of the application can be applied to LTE systems, 5G NR systems, NR evolution systems, 6G systems, IEEE802.11 systems, bluetooth systems, loRa systems, zigbee systems, wireless optical communication systems, passive Internet of things, backscatter communication systems and the like which are applicable to wireless communication systems needing energy beam forming, and the like, and is not limited to the scheme.
In the embodiment of the application, the receiving beam may be expressed as Rx beam, and the receiving beam and the Rx beam may be interchanged. The transmit beam may be denoted as Tx beam and the two may be interchanged.
The beam processing method, the device, the communication equipment and the readable storage medium provided by the embodiment of the application are described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.

Example 1
In this embodiment, several different reporting manners of beam measurement reports are mainly described. Unlike beam measurements in existing NR systems, the first device in the inventive scheme is able to receive Tx beams for both direct and tandem links each time. Also, the Tx/Rx beam in the cascade link may differ from the Tx/Rx beam in the direct link in principle at the time of selection, resulting in the first device taking different signal quality criteria for a first measurement of a first signal on the first Rx beam and a second measurement of a second signal on the second Rx beam. All the above factors lead to the first device reporting the beam measurement report, i.e. the first device is not the control/processing entity and needs to report the beam measurement report, and a new beam measurement report format needs to be designed to meet the requirements.
Independent reporting
A possible solution is that, whether the first device receives/measures the first signal on the first Rx beam and the second signal on the second Rx beam are simultaneous or not, the third device or the fourth device configures the reporting resource of the first measurement report and the reporting resource of the second measurement report to the first device, respectively. Thus, the first device reports the first measurement report and the second measurement report on the time-frequency resources of the first measurement report and on the time-frequency resources of the second measurement report, respectively. Specifically, the first measurement report and the second measurement report may be reported in the same manner as the existing NR system. For the case of multi-panel MTRP/TRP, two reporting forms with NR R15 type can be adopted, namely: group based beam report and Non-group based beam report.
In the Non-group based beam report form, the first device may report the N best beams in one reporting configuration (ReportConfig) or reporting resource. In group based beam report, the first device may report M beams that the first device can simultaneously receive in one ReportConfig or reporting resource. Further, in group based beam report, when the third device or the fourth device configures the first device to perform group based beam report, a resource configuration (such as resource setting) associated with the report is configured in the ReportConfig or the reporting resource configuration, for measuring the measured values of each beam, and then the first device selects M from the measured values and reports the measured values to the third device or the fourth device by using a differential report method. For the case where beam selection and reporting, there are two schemes:
Scheme 1: the first device reports all M beams received simultaneously to the third device or the fourth device.
-Scheme 2: for MPUE, the first device reports a plurality of beam groups (beam groups) to the third device or the fourth device, each beam group corresponds to a panel, and each beam group is composed of a reference signal identifier corresponding to a beam that can be received by the panel. The third device or the fourth device selects one Tx beam from each beam group for subsequent data transmission.
In both schemes Non group based beam report and group based beam report, in order to reduce reporting overhead, when reporting multiple beams in 1 reporting instance, a form of differential reporting may be adopted. Taking the measurement value L1-RSRP as an example, the L1-RSRP value range of beam measurement: -140dBm to-44 dBm (7 bits), the strongest L1-RSRP in all measurements being represented by 7bits (1 dB step), the remaining L1-RSRP values to be reported being reported in 4bits (2 dB step) in a differential manner.
(II) Combined reporting
In the combined reporting, the third device or the fourth device configures the reporting resources of the same with the reporting resources of the first measurement report and the second measurement report for the first device, so that a proper combination mode needs to be designed to meet the reporting requirement. Specific combinations may include, but are not limited to, the following:
(a) Sorting by measurement report
This approach can extend the reporting form of existing NR systems, except that: the first measurement report is immediately followed by a second measurement report. The first measurement report and the second measurement report may be reported in the existing NR, and the same differential or non-differential reporting mode is adopted. As shown in fig. 8A, an example of reporting after sorting based on measurement reports is shown, where the first measurement value in the first measurement report uses L1-RSRP as a signal evaluation criterion and adopts a non-differential reporting manner, and at most two best beams meeting the conditions, that is, the beams corresponding to the first signal identifier #1 and the first signal identifier #3, are allowed to be reported in the first measurement report, so that the content included in the first measurement report is the first signal identifier #1, the first signal identifier #3, the L1-RSRP corresponding to the first signal identifier #1 (that is, the corresponding beam), and the L1-RSRP corresponding to the first signal identifier #3 (that is, the corresponding beam). The second measurement value in the second measurement report takes the L1-SINR as a signal evaluation criterion and adopts a non-differential reporting mode, and the second measurement report allows reporting of at most two best beams meeting the condition, namely, the beam corresponding to the second signal identifier #2 and the second signal identifier #5, so that the content contained in the second measurement report is the second signal identifier #2, the second signal identifier #5, the L1-SINR corresponding to the second signal identifier #2 (namely, the corresponding beam), and the L1-SINR corresponding to the second signal identifier #5 (namely, the corresponding beam).
(B) Combining according to a receive time window
Since the first device receives the first signal and the second signal at different times of different Rx beams, one reporting mode is to perform beam reporting according to the receiving time of the beam meeting the condition, and the first measurement value/the second measurement value may be in a differential or non-differential reporting mode. As shown in fig. 8B, for an example of combined reporting based on the first device receiving time window, the first device may perform segmentation according to a certain time, and report beam measurement values and signal identifications meeting the conditions in different time periods, where the first measurement value of the first signal uses L1-RSRP as the beam signal quality evaluation criterion, and the second measurement value of the second signal uses L1-SINR as the beam signal quality evaluation criterion. In the time window 1, only the signal quality corresponding to the second signal identifier #2 meets the reporting condition; in the time window 2, the signal quality corresponding to the second signal identifier #5 and the first signal identifier #1 meets the respective reporting condition; in the time window 3, only the signal quality corresponding to the first signal identifier #3 satisfies the reporting condition, so that the reporting can be performed in a combination manner shown in fig. 8B.
(C) Combining according to a received Panel index
Because the first device receives the first signal and the second signal on different Rx beams of different Panel, one reporting mode is to report the beam according to the received Panel index of the beam meeting the condition, and the first measurement value/the second measurement value can be in a differential or non-differential reporting mode. As shown in fig. 8C, an example of combined reporting based on the first device receiving the measured values on different Panel, reporting the beam measured values and the signal identifications satisfying the conditions on the respective Panel according to different Panel indexes, wherein the first measured value of the first signal uses L1-RSRP as the beam signal quality evaluation criterion, and the second measured value of the second signal uses L1-SINR as the beam signal quality evaluation criterion. On panel#1, only signal quality corresponding to first signal identifier #3 satisfies reporting condition; on Panel #2, signal quality corresponding to the second signal identifier #5 and the first signal identifier #1 meets respective reporting conditions; on Panel 3, only the signal quality corresponding to the second signal identifier #2 satisfies the reporting condition, so that the reporting can be performed in the combination manner of fig. 8C.
(D) Combining according to reporting content classification
In this combination, the reporting does not distinguish between time window, panel and link, but combines according to the reporting content classification, where the measured value area may take the form of differential or non-differential reporting. As shown in fig. 8D, in an example of the report based on the report content classification combination, according to the respective evaluation criteria, only the first signal identifier #1, the first signal identifier #3, the second signal identifier #2, and the beam corresponding to the second signal identifier #5 satisfy the respective report conditions, so that the four signal identifiers are put together in the signal identifier area; its corresponding L1-RSRP or L1-SINR is placed in the next measurement region, which may take differential or non-differential form; other content areas may place PMI, RI, etc. information as shown in fig. 8D.
Example two
In the second embodiment, a manner in which the second device generates the first signal will be described.
First, the second device autonomously generates a first signal
This approach is suitable for a second device to be powered to be a device with an autonomously generated carrier, such as a passive or semi-passive UE device, which may generate a corresponding first signal depending on configuration information. The corresponding first signal generation and configuration modes are as follows:
(1) The fourth device configures parameters of the first signal of the first device, the parameters comprising:
(a) Time domain related parameters;
(b) Frequency domain related parameters;
(c) A modulation mode;
(d) A transmission power;
(e) The manner of sequence generation.
(2) The third device transmits a third signal at a different Tx beam.
For example, the third signal is only used for radio frequency powering of the second device.
(3) And generating the first signals by the UE according to the parameters of the configured first signals, and transmitting a plurality of first signals.
For example, the first signal may be an SRS, a newly designed L1 signal, CSI-RS, PSSS, SSSS, or the like.
For example, the time domain resources of the plurality of first signals are different, the frequency domain resources are the same or different, and the time-frequency domain resources of the plurality of first signals belong to the same resource set.
(II) the second device generates the first signal based on the backscatter signal
This solution is suitable for BSC devices where the second device to be powered does not itself have autonomously generated carriers, and requires other devices to provide it with radio frequency carriers for backscatter transmission, including passive or semi-passive BSC devices. The corresponding first signal generation and configuration modes are as follows:
(1) The fourth device configures parameters of the first signal of the second device, the parameters comprising:
(a) Time domain related parameters;
(b) Frequency domain related parameters;
(c) A modulation mode;
(d) A transmission power;
(e) The manner of sequence generation.
(2) The third device transmits a third signal at a different Tx beam.
For example, the third signal is used to power the BSC apparatus while providing the BSC apparatus with a radio frequency carrier.
(3) The second device generates the first signal based on the third signal and transmits a plurality of first signals according to the configured parameters of the first signal.
For example, the first signal may be an SRS, a newly designed L1 signal, CSI-RS, PSSS, SSSS, or the like.
For example, the time domain resources of the plurality of first signals are different, the frequency domain resources are the same or different, and the time-frequency domain resources of the plurality of first signals belong to the same resource set.
For example, the first signal is a backscatter signal of the second signal.
(III) the second device directly forwards the first signal
This solution is suitable for BSC devices where the second device to be powered does not itself have autonomously generated carriers, and requires other devices to provide it with radio frequency carriers for backscatter transmission, including passive or semi-passive BSC devices. But unlike (two) generating a back-scattered signal based on load impedance modulation, here the incident third signal is directly reflected according to a fixed reflection coefficient, or is subjected to all 1 modulation, thus generating the first signal, which is thus a direct-forward signal of the third signal. The corresponding first signal generation mode and configuration method are as follows:
(1) The fourth device configures parameters of the first signal of the second device, the parameters comprising: reflection coefficient.
(2) The third device transmits a plurality of third signals at different Tx beams.
For example, part of the power of the third signal may be used for powering the second device, which itself is also the reference signal.
For example, the third signal may be SRS, a newly designed L1 signal, CSI-RS, PSSS, SSSS, or the like.
For example, the time domain resources of the plurality of third signals are different, the frequency domain resources are the same or different, and the time-frequency domain resources of the plurality of third signals belong to the same resource set.
(3) The second device directly reflects the plurality of third signals transmitted by the third device at different Tx beams, i.e., transmits the plurality of first signals, according to the configured reflection coefficient.
The reflected first signal is a back scattering signal of a third signal sent by the third device, and is only subjected to no modulation, or is subjected to all 1 modulation and resource mapping. At this time, the first signal is the third signal.

In the architecture shown in fig. 10, the first device is a base station device, the second device is a UE or BSC device that needs radio frequency power, the third device is a Legacy UE device, and the first device needs to demodulate information from the third device and the second device at the same time. In this architecture, since the main body for performing measurement is the base station device, compared to the above (one) in which the base station is PTx and the UE is IRx, the UE needs to perform the beam measurement report reporting procedure, and there is no reporting procedure in this architecture. The scheme is as follows:
(1) The first device determines parameters of a first Rx beam of the first device and a first Tx beam of the third device based on a first measurement of a first signal transmitted by the second device to the first device, and determines parameters of a second Rx beam of the first device and a second Tx beam of the third device based on a second measurement of a second signal transmitted by the third device to the first device, and configures a TCI state indicating the third device.

(III) As shown in FIGS. 11A and 11B, the first device is a UE, the third device is a UE, beam training/processing is performed by the first device (shown in FIG. 11B), or beam training/processing is performed by the third device (shown in FIG. 11A).
In the architecture shown in fig. 11A and 11B, the third device is a Legacy UE device, the second device is a UE or BSC device that needs radio frequency power, the first device is a Legacy UE device, and beam training/processing is performed by the first device (shown in fig. 11B), or beam training/processing is performed by the third device (shown in fig. 11A). The architecture is applicable to situations where there is no network deployment, similar to the Mode2 (d) scenario in sidelink. In this scenario, legacy UEs of the first device and the third device may both become master UEs, i.e., execution bodies, to implement resource allocation, parameter configuration, scheduling, and the like. In general, the scenario is applicable to energy supply and data transceiving, which are completed by Legacy UE and UE/BSC device to be supplied with energy, and the deployment is flexible, and because Legacy UE is generally closer to BSC device, radio frequency energy and uplink and downlink coverage with higher energy efficiency can be provided.
Specifically, for the case that the master UE is the third device, the scheme is basically the same as the scheme in the above (a), and the difference is that:

However, because the energy supply and the data receiving and transmitting are completed by the Legacy UE and the UE/BSC device to be powered, the deployment is flexible, and because the Legacy UE is generally closer to the BSC device, the Legacy UE can also provide radio frequency energy and uplink and downlink coverage with higher energy efficiency.
