In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
For the purposes of promoting an understanding of the principles and advantages of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same.
The principle of operation of backscatter communication is to produce a modulated reflection (backscatter modulation) in an incident radio frequency wave that can be received by a receiver (reader) that is a backscatter communication device. In general, reflection of backscatter communications is produced by changing the impedance of an antenna tuned to resonate at the desired radio frequency signal frequency. In this way, a wireless node or "tag" may be placed in almost all environments without a power source and may be powered by the tag. The tag may be interrogated by a reader, which may send information to the tag or receive information sent by the tag. In a multiple access scenario, a single reader may serve multiple tags distributed throughout the environment, enabling the tags to perform sensing/data logging information on demand or continuously.
Another method of backscatter communication is to use radio frequency signals already present in the environment, such as WiFi, cellular communication, AM/FM (Amplitude Modulation/Frequency Modulation ) radio, digital television, etc. The backscatter communications network can be operated without a reader powering on the tag using existing radio frequency signals already present in the environment. These tags may operate as mesh networks and store data for transmission at a later query or when communicating with a gateway that allows access to a wider network. In this way, a lower power wireless node may be implemented without using an energy-expensive radio frequency transmitter within the node, or a backscatter communication technology may be incorporated in a typical internet of things wireless node, thereby providing the option of lower power wireless communication, thereby extending battery life in the presence of externally viable radio frequency signals.
Fig. 1 is a flow diagram of some embodiments of a state switching method of the present disclosure, performed by a communication device, which is a backscatter communication device.
In step 110, base station status information is obtained.
In some embodiments, the base station state information includes whether the base station is in a communication state or the base station is in a non-communication state.
In step 120, the state of the communication device is switched according to the data transmission requirements of the communication device and the base station state information, wherein the state of the communication device comprises one of a backscatter communication state, a collect energy state, and an active communication state.
In some embodiments, the communication device is in a backscatter communication state where the base station is in a communication state and the communication device has a data transmission requirement. When the communication device is in a backscattering communication state, the signal of the base station is used as an excitation source to transmit data with the receiver.
For example, the communication device is provided with excitation carrier detecting means for detecting whether an excitation carrier is present in the environment for backscatter communication.
In some embodiments, the communication device is in a harvested energy state with the base station in a communication state and the communication device having no data transmission requirements. When the communication device is in a state of collecting energy, the modulation transmitter is turned off and the energy collecting function is turned on. If there is a burst data transmission, the communication device can switch the state to a backscatter communication state or an active communication state at any time.
In some embodiments, the communication device is in an active communication state where the base station is in a non-communication state and the communication device has a data transmission requirement. The communication device uses the collected energy to transmit a signal to the receiver while the communication device is in an active communication state.
In the above embodiment, the communication device can switch among three states of the back scattering communication state, the energy collection state and the active communication state according to the data transmission requirement and the base station state information, so as to meet different communication requirements.
Fig. 2 is a flow chart illustrating other embodiments of a state switching method of the present disclosure. In this embodiment, the backscatter communication state is divided into a first communication state and a second communication state.
In step 210, indication information sent by the base station is received, where the indication information includes whether a communication link needs to be provided by the communication device for the base station and the receiver.
The communication link is provided for the base station and the receiver by the communication device, i.e. multipath is provided for the base station and the receiver. For example, the receiver periodically reports the signal strength of the direct link signal received by the receiver, and if the signal transmitted by the transmitter of the base station to the receiver over the direct link is weak, the transmitter of the base station transmits multipath indication information to the communication device.
In some embodiments, the indication information is determined according to the transmit power and modulation scheme of the base station.
For example, in the case where the transmission power of the base station is greater than the power threshold and the modulation scheme is frequency modulated or amplitude modulated, the indication information is that a communication link needs to be provided between the base station and the receiver by the communication device. In this embodiment, the modulation scheme may be used as an excitation source for the communication device.
For another example, in the case where the transmit power of the base station is less than or equal to the power threshold, or the modulation scheme is phase modulation, the indication information is that it is not necessary to provide a communication link for the base station and the receiver through the communication device.
In some embodiments, the indication information is transmitted by the base station to the communication device over a broadcast channel.
The base station transmits the indication information to the communication device through, for example, a PBCH (Physical Broadcast Channel ).
In some embodiments, the indication information may also be sent by the base station to the communication device by multicast or the like.
In some embodiments, if there are multiple communication devices in the environment, the base station can send indication information to the multiple communication devices.
In step 220, the communication device is controlled to be in a first communication state or a second communication state different from the first communication state according to the indication information.
In some embodiments, the first communication state is a reciprocal communication state, i.e., the communication device is transmitting first information to the receiver over the backscatter link and forwarding second information that the base station transmits to the receiver when the communication device is in the first communication state.
In some embodiments, the second communication state is an interfering communication state.
In this embodiment, as shown in fig. 3, the reciprocal communication and the interference communication are described by taking the environmental backscatter communication as an example.
The ambient communication system receiver 310 receives the communication signal from the ambient communication system transmitter 320 while the ambient communication system transmitter 320 signals serve as the radio frequency excitation of the reflective communication system with which the reflective device 330 of the reflective communication system communicates with the reflective communication system receiver 340. As can be seen from fig. 3, there are two interfering links, the first being direct link interference from the ambient communication system transmitter to the reflective communication system receiver and the second being reflective link interference from the reflective communication system reflective device to the ambient communication system receiver.
If the reflecting device is able to use its reflecting capabilities to provide multipath for the ambient communication system, the ambient communication system will have a better signal-to-noise ratio, thereby canceling the interference of the reflecting link with the ambient communication system. At this time, the environmental communication system provides an excitation source for the transmitting communication system, the transmitting communication system provides multipath for the environmental communication system, and reciprocal communication is realized between the two systems.
In the present disclosure, as shown in fig. 4, signal transmission is performed between a base station 410 and a receiver 420 through a direct link. The base station 410 sends indication information to the communication device 430 that provides multipath to the base station and the receiver, if the communication device 410 has a data transmission requirement, signal transmission is performed through the reflection link, and since the base station 410 is in the communication state, the communication device 410 is switched to the first communication state, and at this time, reciprocal communication is implemented between the communication device 410 and the receiver 420 and between the base station 410 and the receiver 420. If the base station 410 does not send the indication information to the communication device 430 that provides multipath to the base station and the receiver, or if the indication information sent by the base station 410 to the communication device 430 is that the communication device is not required to provide multipath to the base station and the receiver, but the communication device 410 has a data transmission requirement, and the base station 410 is in a communication state, the communication device 410 switches to a second communication state, where communication between the communication device 410 and the receiver 420 may interfere with communication between the base station 410 and the receiver 420.
In the above embodiment, the communication device may be further specifically divided into two states in the backscattering communication state, so as to greatly improve the completeness of the reciprocal communication technical scheme, and facilitate improving the spectrum utilization rate and the resource utilization rate.
In some embodiments of the present disclosure, the communication device is in a collect energy state with the base station in a communication state and the communication device is free of data transmission requirements, and the modulation transmitter of the communication device is in an off state with the communication device in a collect energy state.
In this embodiment, the communication device is provided with energy collecting and storing means, for example, the communication device collects light energy, wind energy, electromagnetic energy and other energy, which is used for emergency data transmission when the communication device is not excited in the environment, thereby improving the effect and stability of data transmission.
