The method, the device and the equipment for transmitting the back-scattered communication BSC data provided by the embodiment of the application are described in detail through some embodiments and application scenes thereof by combining the attached drawings.

In order to better understand the scheme of the embodiment of the present application, the following description will first describe the relevant content of the BSC.

BSC refers to a backscatter communication device that uses radio frequency signals in other devices or environments to signal modulate to transmit its own information. The backscatter communication device (BSC TAG, which may also be referred to as BSC UE), may be a TAG in conventional radio frequency identification (Radio Frequency Identification, RFID) or a Passive internet of things (Internet of Things, ioT) device.

The backscattering (backscattering) technology is a passive or low-energy technology, and is technically characterized in that the transmission of self signals can be completed by changing the characteristics of received environmental radio frequency signals, such as phase or amplitude information, so that the information transmission with extremely low power consumption or zero power consumption is realized.

From the energy supply aspect, the backscatter communication devices (BSC TAGs) can be divided into three modes, fully Passive (Passive), semi-Passive (Semi-Passive) and active (active).

For passive backscatter communication, the BSC TAG first obtains energy from external electromagnetic waves (Energy harvesting) and supplies internal channel coding and modulation circuit modules to operate, and at the same time, communicates with the backscatter radio frequency signal, thereby realizing zero power consumption communication.

For the semi-passive BSC TAG, its internal circuit module is powered by its own battery and communicates by back-scattering radio frequency signals. Because the internal battery is only used for the operation of simple internal circuit modules such as channel coding and modulation and the like and the power consumption is very low, the service life of the BSC TAG battery can reach more than ten years. All of the externally supplied rf signals may be used for reverse communication without storing some of the energy to power.

For the active BSC TAG, the built-in battery is not only used for simple internal circuit operations such as channel coding and modulation, but also used for circuit operations such as Power Amplifier (PA) and low noise Amplifier (Low Noise Amplifier, LNA), so that more complex signal modulation and demodulation of backscatter communication can be realized.

Fig. 2 is a schematic diagram of a possible application scenario of the BSC, and fig. 2 shows that the terminal is connected as a control device (Reader) for back-scattering and as a smart glasses for back-scattering communication device (Tag). The backscatter communication device (Tag) collects the energy of the signal transmitted by the terminal or the energy provided by the dedicated device, and transmits the information b (t) of the backscatter communication device (Tag) by reflecting the signal x (t) transmitted by the terminal.

From the architecture of the backscatter communication, it can be further divided into a single-base backscatter communication system (Monostatic backscatter communicaiton system, MBCS), a double-base backscatter communication system (Bistatic backscatter communicaiton systems, BBCS) and an ambient backscatter communication system (Ambient backscatter communication systems, ABCS).

Fig. 3 is a schematic diagram of MBCS, where, as shown in fig. 3, the MBCS system includes a BSC transmitting end (such as Tag) and a Reader. The Reader includes a radio frequency identification (frequency identification, RF) radio frequency source and a BSC receiving end, wherein the RF radio frequency source is configured to generate RF radio frequency signals to power the BSC transmitting end/Tag. The BSC transmitting end receives the back scattered signal by back scattering the modulated RF signal, and then carries out signal demodulation. Because the RF source and the BSC receiving end are in the same device, e.g., in the Reader/writer, it is referred to as a single-station backscatter communication system. In MBCS systems, the energy attenuation of signals is large because the RF radio frequency signals sent from the BSC transmitting end experience double near-far effects due to the signal attenuation of round-trip signals, and MBCS systems are typically used for short-range backscatter communications, such as conventional radio frequency identification (Radio Frequency Identification, RFID) applications.

Fig. 4 is a schematic diagram of a BBCS system, in which the RF source and the BSC receiving end are separate, unlike the MBCS system, as shown in fig. 4. Therefore, the BBCS avoids the problem of large round trip signal attenuation, and in addition, the performance of the BBCS communication system can be further improved by reasonably placing the position of the RF radio frequency source. Notably, environmental backscatter communications ABCS is also one type of bistatic backscatter communications, but the radio frequency sources in BBCS systems are dedicated signal radio frequency sources, which can be available in the environment, such as: television towers, cellular base stations, wireless fidelity (Wireless Fidelity, wiFi) signals, bluetooth signals, etc.

The cellular networking architecture of the BSC is described in detail below. The back-scattering communication cellular network architecture can be specifically divided into various architectures as shown in fig. 5-12 from different radio frequency sources, uplink data transmission and downlink data transmission, wherein the architecture shown in fig. 5 does not contain auxiliary equipment in the BSC system, and the architecture shown in fig. 6-12 contains auxiliary equipment in the BSC system.

The deployment architecture has high requirements on the receiving sensitivity of network side equipment and BSC TAG, but the architecture deployment is simple.

In the embodiment of the application, the BSC TAG can send a TAG request to the first equipment, wherein the TAG request is used for initiating BSC link establishment. Thus, in each cellular organization architecture, the BSC TAG can be flexibly supported to initiate the BSC link establishment operation. In addition, in each architecture as shown in fig. 7-12, the terminal does not need to actively monitor, and only after the BSC TAG is monitored to initiate the establishment of the BSC link, the forwarding of uplink data and/or downlink data is performed, so that the power consumption of the terminal can be reduced.

It should be noted that, in the embodiments of the present application, descriptions such as BSC communication, BSC link establishment, BSC connection, and BSC data transmission include operations such as signaling interaction and/or data transmission between a BSC TAG and a terminal or a network side device based on a BSC communication mode. Establishing a BSC link also refers to establishing an uplink and/or downlink between the BSC TAG and the terminal or network side device.

Fig. 13 is a flowchart of a method for initiating a BSC link establishment provided by the present application, and the method for initiating a BSC link establishment provided by the embodiment of the present application is described below with reference to fig. 13. As shown in fig. 13, the method includes:

That is, in the BSC system, no auxiliary device is included, the BSC TAG may send a TAG request to the network side device, where the TAG request is used to initiate BSC link establishment. After receiving the Tag request, the network side device sends a first network message to the BSC Tag, where the first network message is used to instruct the network side device to confirm establishment of the BSC link. It should be understood that the first network message is used to instruct the network side device to confirm the BSC link establishment, and may also be understood to instruct the network side device to confirm the Tag request.

The auxiliary equipment monitors a message sent by the BSC TAG, and after receiving a TAG request sent by the BSC TAG, the auxiliary equipment sends a first message to the network side equipment, wherein the first message is used for indicating the BSC TAG to initiate BSC link establishment to the network side equipment.

The first message is used for indicating the BSC TAG to initiate BSC link establishment to the network side equipment, or can be used for requesting the network side equipment to establish BSC connection or establishing BSC link. The first message may be a UE request message, for example.

In this embodiment, after receiving the TAG request sent by the BSC TAG, the auxiliary device returns a first message to the BSC TAG, so as to initiate BSC link establishment, thereby initiating BSC link establishment in a BSC system including the auxiliary device.
