[0059] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0060] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "plurality" means two or more. The words "first", "second", etc. do not limit the quantity and execution order, and the words "first", "second", etc. do not limit them to be different.

[0061] It should be noted that in the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0062] At present, the passive-internet of things (Passive-IoT) has received widespread attention. The passive terminals in the passive-IoT have the advantages of no need for external power supply, strong adaptability, high reliability, high security, low cost, easy installation and good maintainability, so they are widely used in many fields. However, the passive terminal needs to collect energy from the environment, and the energy collection efficiency may be low, which may further limit the working time, working distance, range, etc. of the device.

[0063] In view of this, the present disclosure provides a data information transmission method, the method comprising: generating a first signal consisting of a high level pulse and a low level pulse based on an information sequence, and sending the first signal. In this way, while transmitting information to a receiving end, the high level pulse in the first signal can also be used to provide energy to the receiving end.

[0064] In some embodiments, in a passive Internet of Things, a communication mode based on backscattering can be used to transmit information to a receiving end.

[0065] Backscatter communication (BSC) is a wireless communication technology that uses the principle of backscattering of radio frequency signals for communication. In backscatter communication, the transmitting device can enhance the reflection of the incident radio frequency signal by adjusting the matching between the receiving antenna and the impedance, and modulate the sensed data it obtains onto the reflected signal to complete the data transmission.

[0066] To facilitate understanding of the technical solution provided by the present disclosure, Figure 1 A communication system is shown in FIG. 1 , which can use the above-mentioned backscatter communication technology. Figure 1 As shown, the communication system 100 includes a transmitting device 101 , a reverse communication device 102 and a receiving device 103 .

[0067] The sending device 101 may also be called a helper, an exciter or an excitation device, etc., without limitation. The reverse communication device 102 may also be called a backscatter device, a reflection device, an electronic tag, or a tag, etc., without limitation. The receiving device 103 may also be called a receiver, a receiver or a reader / writer, etc., without limitation. The sending device may also be a base station, a reader / writer, a relay device, etc., and the receiving device may also be a base station, a reader / writer, a relay device, etc. The sending device and the receiving device may be the same or different. The excitation device mainly sends an excitation signal to provide energy and carrier to the tag to activate the tag. The tag is a passive device. When it receives the excitation signal sent by the excitation device, it starts to reflect the signal. The tag can be considered as a full-duplex device. While receiving energy / signal / carrier, it also modulates and reflects its own information. The reader / writer can control the excitation device to send instructions and excitations, and receive information from the tag at the same time. In some scenarios, the excitation device and the receiving device can be integrated into one device, that is, the integrated device can both send excitation signals and have the function of receiving reflected signals. In some scenarios, the excitation device and the receiving device may adopt a separate architecture, that is, the excitation device and the receiving device are two devices respectively, wherein the excitation device is used to send the excitation signal and the receiving device is used to receive the reflected signal. It should be noted that the embodiments of the present disclosure are all described in the scenario where the excitation device and the receiving device in the backscatter communication system are two devices respectively.

[0068] The method provided by the present invention can be applied to any current or future communication system that adopts reflection communication technology, such as global system of mobile communication (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, general packet radio service (GPRS), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) communication system, fifth generation (5G) system or new radio (NR) and future communication systems, etc., without limitation herein.

[0069] In some embodiments, the excitation device involved in the embodiments of the present disclosure may be a network device, and the reader / writer may be a terminal device. Alternatively, the excitation device is a terminal device, and the reader / writer is a network device, or both the excitation device and the reader / writer may be network devices, or both the excitation device and the reader / writer may be terminal devices, etc., without limitation. The excitation device may send an excitation signal to the tag on a specified time-frequency resource under the coordination and control of the reader / writer to complete the communication process. For example, in the application scenario of the Internet of Things, the tag device can be used as a low-cost tag and installed on objects in large quantities. The network device and the terminal device can charge the tag device to obtain information when the electronic tag information is needed.

[0070] The network device can be used to implement functions such as resource scheduling, wireless resource management, and wireless access control of the terminal device. Specifically, the network device can be any node in a base station transceiver, a wireless base station, a wireless transceiver, a small base station, a wireless access point, a transmission receive point (TRP), a transmission point (TP), an evolved node B (eNB), a home node B, a home evolved node B, a reader, and some other access nodes. In some embodiments, the communication system 100 may also include different types of base stations, such as a macro cell base station and / or a small cell base station.

[0071] The terminal device may also be referred to as a terminal, user equipment (UE), mobile station, mobile terminal, etc. The terminal device may be an Internet of Things (IoT) device, which is used for various information collection and then forward error correction coding of the data information before sending the data to the base station. The terminal device may also be a mobile phone, a tablet computer, a computer with wireless transceiver function, a car, a tram and other mobile devices. In addition, the terminal device may be fixed or mobile. Various types of terminal devices may also include or be referred to by those skilled in the art as mobile stations, user stations, mobile units, user units, wireless units, remote units, mobile devices, wireless devices, wireless communication devices, remote devices, mobile user stations, access terminals, mobile terminals, wireless terminals, remote terminals, handheld devices, user agents, mobile clients, clients, passive tags, or some other possible devices. In addition, various types of UE may also be cellular phones, personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, tablet computers, laptop computers, cordless phones, wireless local loop (WLL) stations, and the like. Various types of UEs may communicate with various types of base stations and network devices (including macro eNBs, small cell eNBs, relay base stations, etc.) The wireless communication system 100 may also include an IoT system or be a part of an IoT system.

[0072] like Figure 2 As shown, an information transmission method provided by an embodiment of the present disclosure includes the following steps:

[0073] S101 . Generate a first signal consisting of a high-level pulse and a low-level pulse based on an information sequence.

[0074] The above information sequence is a sequence generated based on the data to be transmitted. In addition, the length of the information sequence may be K bits, where K≥1.

[0075] In some embodiments, the length of the information sequence is determined in one of the following ways: pre-set, configured by signaling. Exemplarily, the transmitting end device may receive a signaling indicating the length of the information sequence (i.e., the value of K), for example, the length of the information sequence is 1 bit, and then based on the signaling, the transmitting end device may determine the information sequence of 1 bit in length.

[0076] In a possible implementation, a second signal consisting of a high-level pulse and a low-level pulse may be generated first, and then the first signal may be generated based on the second signal. Figure 3 As shown, it can be specifically implemented as the following steps S101A1-S101A2:

[0077] S101A1. Generate a second signal consisting of a high-level pulse and a low-level pulse based on the information sequence.

[0078] The different characteristics of the second signal correspond to different information sequences, that is, the different characteristics of the second signal correspond to different information sequences of K bits in length.

[0079] In some embodiments, different characteristics of the second signal correspond to different information sequences, including at least one of the following: different lengths of the second signal correspond to different information sequences, different combination orders of high-level pulses and low-level pulses in the second signal correspond to different information sequences, different width combinations of high-level pulses and / or low-level pulses in the second signal correspond to different information sequences, different widths of high-level pulses and / or low-level pulses in the second signal correspond to different values ​​of a bit in the information sequence, different width ratios between two consecutive high-level pulses in the second signal correspond to different values ​​of a bit in the information sequence, different width ratios between two consecutive low-level pulses in the second signal correspond to different values ​​of a bit in the information sequence, and different width ratios between a consecutive high-level pulse and a low-level pulse in the second signal correspond to different values ​​of a bit in the information sequence.

[0080] In some embodiments, the above information sequence may also correspond to multiple sequence states, and the multiple sequences may be divided into multiple groups. Exemplarily, the above information sequence may be a K-bit long information sequence, and the K-bit long information sequence may correspond to 2 k sequence state, and then 2 k The sequence states are divided into multiple groups.

[0081] In the above-mentioned multiple groups of sequence states, the lengths of the information sequences corresponding to the sequence states belonging to the same group are the same, wherein the sequence states belonging to the same group are different, and different width combinations of high-level pulses and / or low-level pulses in the second signal correspond to different sequence states belonging to the same group. In addition, the signal lengths of the second signals corresponding to the sequence states belonging to different groups are different.

[0082] In some embodiments, the second signal is generated based on the information sequence through a preset waveform coding method or mapping method.

[0083] In one example, the preset waveform coding method may be a Manchester waveform coding method with a rate of 1 / 2 or a Manchester waveform coding method with a rate of 1 / 4. That is, the second signal may be generated based on an information sequence of K bits in length and using a Manchester waveform coding method with a rate of 1 / 2 or 1 / 4.

[0084] For example, Figure 4 As shown, the value of K is 1, and the second signal is generated by using a Manchester waveform encoding method with a rate of 1 / 2. Figure 4 Indicator boxes 41, 42, and 43 in the figure are all possible second signals, and different characteristics of the second signal correspond to different information sequences. In one example, different combinations of high-level pulses and low-level pulses in the second signal correspond to different information sequences, such as Figure 4 As shown, K=1, the bit value of the information sequence is 0, and the second signal is composed of a low-level pulse and a high-level pulse with equal pulse width. The bit value of the information sequence is 1, and the second signal is composed of a high-level pulse and a low-level pulse with equal pulse width.

[0085] S101A2. Add M unit high-level pulses and N unit low-level pulses to the second signal to generate a first signal.

[0086] Wherein, M is an integer greater than or equal to 1, N is an integer greater than or equal to 0, and M is greater than N.

[0087] In some embodiments, the pulse width of the above-mentioned unit high-level pulse and the pulse width of the unit low-level pulse are determined according to one of the following methods: a preset pulse width value, configured through signaling.

[0088] In an example, the value of N may be 0, that is, M unit high-level pulses may be added to the second signal to generate the first signal.

[0089] In some embodiments, in the first signal, M unit high-level pulses satisfy at least one of the following: M1 unit high-level pulses are located before the first pulse in the second signal, M2 unit high-level pulses are located after the last pulse in the second signal, and M3 unit high-level pulses are located within the second signal. Wherein, M1, M2, and M3 are all integers less than or equal to M, and the sum of M1, M2, and M3 is equal to M.

[0090] Exemplarily, the value of M1 is equal to M, and the values ​​of M2 and M3 are both 0, that is, the M unit high-level pulses are all located before the first pulse of the second signal. Alternatively, the value of M2 is equal to M, and the values ​​of M1 and M3 are both 0, that is, the M unit high-level pulses are all located after the last pulse of the second signal. Alternatively, the values ​​of M1 and M2 are greater than 0, and the value of M3 is 0, that is, the M unit high-level pulses include two parts, one part of which is M1 unit high-level pulses, which are located before the first pulse of the second signal, and the other part is M2 unit high-level pulses, which are located after the last pulse of the second signal. It should be understood that the above is only an exemplary description of the values ​​of M1, M2 and M3, and there are many other possible situations for the values ​​of M1, M2 and M3, which are not listed here one by one.

[0091] Furthermore, the present embodiment is exemplarily described below with reference to Examples 1 to 3.

[0092] Example 1: Figure 4 As shown, the value of K is 1, and M=1, and the second signal is generated by using the Manchester waveform encoding method with a rate of 1 / 2. Among them, the pulse width of the unit high / low level pulse is PW, such as Figure 4 As shown in the second signal in the indicator box 41 in FIG. 4 , in the first signal, all of the M=1 unit high-level pulses are located before the first pulse of the second signal. Moreover, the proportion of the high-level pulses of the first signal to all pulses of the first signal is 2 / 3.

[0093] Or, if Figure 4 As shown in the second signal in the indicator box 42 in FIG. 4 , in the first signal, M=1 unit of high-level pulses are all located in the second signal. Moreover, the proportion of the high-level pulses of the first signal to all pulses of the first signal is 2 / 3.

[0094] Or, if Figure 4 As shown in the second signal in the indicator box 43 in FIG. 4 , in the first signal, all of the M=1 unit high-level pulses are located after the last pulse of the second signal.

Figure 5As shown in the second signal in the indicator box 51 in FIG. 5 , in the first signal, M=2 unit high-level pulses are all located before the first pulse of the second signal. Moreover, the proportion of the high-level pulses of the first signal to all pulses of the first signal is 3 / 4.

[0096] Or, if Figure 5 As shown in the second signal in the indicator box 52 in FIG. 5 , in the first signal, M=2 unit high-level pulses are all located in the second signal. Moreover, the proportion of the high-level pulses of the first signal to all pulses of the first signal is 3 / 4.

[0097] Or, if Figure 5 As shown in the second signal in the indicator box 53 in FIG. 5 , in the first signal, M=2 unit high-level pulses are all located after the last pulse of the second signal. Moreover, the proportion of the high-level pulses of the first signal to all pulses of the first signal is 3 / 4.

[0098] Or, if Figure 5 As shown in the second signal in the indicator box 54 in the first signal, in the first signal, M=2 unit high-level pulses include two parts, each of which includes 1 high-level pulse, wherein one part of the high-level pulses is located before the first pulse of the second signal, and the other part is located after the last pulse of the second signal. Moreover, the proportion of the high-level pulses of the first signal to all the pulses of the first signal is 3 / 4.

[0099] In addition, if Figure 5 As shown, different combinations of high-level pulses and low-level pulses in the second signal correspond to different information sequences, where K=1, the bit value of the information sequence is 0, and the second signal is composed of a sequence of low-level pulses and high-level pulses with equal pulse widths. Alternatively, the bit value of the information sequence is 1, and the second signal is composed of a sequence of high-level pulses and low-level pulses with equal pulse widths.

[0100] Example 3: Figure 6 As shown, the value of K is 1, and M=1, and the second signal is generated by using the Manchester waveform encoding method with a rate of 1 / 4. Among them, the pulse width of the unit high / low level pulse is PW, Figure 6 The indication boxes 61, 62 and 63 in FIG. 6 are all possible second signals. Figure 6 As shown in the second signal in the indicator box 61 in FIG. 1 , in the first signal, all of the M=1 unit high-level pulses are located before the first pulse of the second signal. Moreover, the proportion of the high-level pulses of the first signal to all pulses of the first signal is 3 / 5.

[0101] Or, if Figure 6As shown in the second signal in the indicator box 62 in FIG. 1 , in the first signal, all of the high-level pulses of M=1 unit are located in the second signal. Moreover, the proportion of the high-level pulses of the first signal to all the pulses of the first signal is 3 / 5.

[0102] Or, if Figure 6 As shown in the second signal in the indicator box 63 in FIG. 1 , in the first signal, all of the M=1 unit high-level pulses are located after the last pulse of the second signal. Moreover, the proportion of the high-level pulses of the first signal to all the pulses of the first signal is 3 / 5.

[0103] In addition, if Figure 6 As shown, different combinations of high-level pulses and low-level pulses in the second signal correspond to different information sequences, where K=1, the bit value of the information sequence is 0, and the second signal is composed of two low-level pulses and two high-level pulses with equal pulse widths, alternating in sequence. Alternatively, the bit value of the information sequence is 1, and the second signal is composed of two high-level pulses and two low-level pulses with equal pulse widths, alternating in sequence.

[0104] In another example, the value of N may be greater than 0, that is, M unit high-level pulses and N unit low-level pulses are added to the second signal to generate the first signal.

[0105] In some embodiments, in the first signal, N unit low-level pulses satisfy at least one of the following: N1 unit low-level pulses are located before the first pulse in the second signal, N2 unit low-level pulses are located after the last pulse in the second signal, and N3 unit low-level pulses are located in the second signal. Wherein. N1, N2 and N3 are integers less than or equal to N, and the sum of N1, N2 and N3 is equal to N. And, in the first signal, M unit high-level pulses satisfy at least one of the following: M1 unit high-level pulses are located before the first pulse in the second signal, M2 unit high-level pulses are located after the last pulse in the second signal, and M3 unit high-level pulses are located in the second signal. Wherein, M1, M2 and M3 are integers less than or equal to M, and the sum of M1, M2 and M3 is equal to M.

[0106] Exemplarily, the value of M1 is equal to M, the value of N1 is equal to N, and the values ​​of M2, M3, N2 and N3 are all 0, that is, the M unit high level pulses and the N unit low level pulses are all located before the first pulse of the second signal. Alternatively, the value of M2 is equal to M, the value of N2 is equal to N, and the values ​​of M1, M3, N1 and N3 are all 0, that is, the M unit high level pulses and the N unit low level pulses are all located after the last pulse of the second signal. Alternatively, the values ​​of M1, M2, N1, and N2 are all greater than 0, and the values ​​of M3 and N3 are all 0, that is, the M unit high-level pulses include two parts, one part of which is M1 unit high-level pulses, which are located before the first pulse of the second signal, and the other part is M2 unit high-level pulses, which are located after the last pulse of the second signal, and the N unit low-level pulses also include two parts, one part of which is N1 unit low-level pulses, which are located before the first pulse of the second signal, and the other part is N2 unit low-level pulses, which are located after the last pulse of the second signal. It should be understood that the above is only an exemplary description of the values ​​of M1, M2, M3, N1, N2, and N3, and there are many other possible situations for the values ​​of M1, M2, M3, N1, N2, and N3, which are not listed here one by one. In addition, the following example 4 is used to exemplarily describe this embodiment.

Among them, the pulse width of the unit high / low level pulse is PW, such as Figure 7 As shown in the second signal in the indicator box 71 in FIG. 1 , in the first signal, M=2 unit high level pulses and N=1 unit low level pulses are both located before the first pulse of the second signal. Moreover, the proportion of the high level pulses of the first signal to all pulses of the first signal is 3 / 5.

[0108] Or, if Figure 7 As shown in the second signal in the indicator box 72 in FIG. 1 , in the first signal, M=2 unit high level pulses and N=1 unit low level pulses are both located in the second signal. Moreover, the proportion of the high level pulses of the first signal to all pulses of the first signal is 3 / 5.

[0109] Or, if Figure 7 As shown in the second signal in the indicator box 73 in FIG. 1 , in the first signal, M=2 unit high level pulses and N=1 unit low level pulses are both located after the last pulse of the second signal. Moreover, the proportion of the high level pulses of the first signal to all pulses of the first signal is 3 / 5.

[0110] In addition, if Figure 7As shown, different combinations of high-level pulses and low-level pulses in the second signal correspond to different information sequences, where K=1, the bit value of the information sequence is 0, and the second signal is composed of a sequence of low-level pulses and high-level pulses with equal pulse widths. Alternatively, the bit value of the information sequence is 1, and the second signal is composed of a sequence of high-level pulses and low-level pulses with equal pulse widths.

[0111] In some embodiments, the high level pulse and the low level pulse in the second signal correspond to one or more modulation symbols of the same length and different amplitude values, and the different amplitudes of the modulation symbols or the presence or absence of data transmission of the modulation symbols correspond to high level pulses and low level pulses, respectively. Exemplarily, the modulation symbol can be, for example, an on-off keying (OOK) modulation symbol, an amplitude shift keying (ASK) modulation symbol, an orthogonal frequency division multiplexing (OFDM) modulation symbol, etc., and the length of the modulation symbol is the duration of the symbol.

[0112] In some embodiments, the length of the second signal is determined based on the duration of the second signal. The duration of the pulse of the second signal is determined based on the pulse width of the high level pulse and the pulse width of the low level pulse in the second signal.

[0113] In some embodiments, the second signal can also be generated based on a signal sequence of length K and a preset mapping method. Furthermore, the first signal can be obtained based on the second signal and another M unit high-level pulses and N unit low-level pulses. Among them, the pulse width of the unit high-level pulse or the unit low-level pulse can be PW, and the pulse width of the unit high-level pulse or the unit low-level pulse can be determined by presetting the pulse width value or by signaling configuration. And, M≥1, N≥0, M>N. In the first signal, the M unit high-level pulses and the N unit low-level pulses can all be located before the second signal, all in the middle of the second signal, or all after the second signal. Alternatively, it can be divided into multiple parts of M unit high-level pulses and N unit low-level pulses, each of which is located before the second signal, in the middle of the second signal, or after the second signal, which will not be repeated here. In addition, the following examples 5-7 are used to exemplarily illustrate this embodiment.

[0114] Example 5, K=1, a signal sequence with a length of K generates a second signal in a preset mapping manner, and different combinations of high-level pulses and low-level pulses in the second signal correspond to different information sequences, such as Figure 8As shown, when the value of the signal sequence is 1, the second signal is formed by sequentially connecting a low-level pulse with a pulse width of PW, a high-level pulse with a pulse width of 2PW, and a low-level pulse with a pulse width of PW. Alternatively, when the value of the signal sequence is 0, the second signal is formed by sequentially connecting a high-level pulse with a pulse width of PW, a low-level pulse with a pulse width of 2PW, and a high-level pulse with a pulse width of PW. Furthermore, M unit high-level pulses and N unit low-level pulses can be added to the second signal to generate the first signal. Fig. 9 As shown in the figure, the pulse width of the unit high / low level pulse is PW, M=1, N=0. Fig. 9 As shown in the second signal in the indicator box 91 in FIG. 1 , M=1 unit high-level pulse is located before the first pulse of the second signal. And, the ratio of the high-level pulse of the first signal to all pulses of the first signal is 3 / 5. Or, as Fig. 9 As shown in the second signal in the indicator box 92 in FIG. , M=1 unit high-level pulse is located in the second signal. And, the ratio of the high-level pulse of the first signal to all pulses of the first signal is 3 / 5. Alternatively, as Fig. 9 As shown in the second signal in the indicator box 93 in FIG. 1 , M=1 unit high level pulse and N=1 unit low level pulse are both located after the last pulse of the second signal. Moreover, the proportion of the high level pulse of the first signal to all pulses of the first signal is 3 / 5.

[0115] Example 6, K=1, a signal sequence with a length of K generates a second signal in a preset mapping manner, and different combinations of high-level pulses and low-level pulses in the second signal represent different k-bit signal sequences, such as Fig.10 As shown, when the bit value of the signal sequence is 1, the second signal is composed of a high level pulse with a pulse width of 2PW and a low level pulse with a pulse width of 2PW connected in sequence. When the bit value of the signal sequence is 0, the second signal is composed of a low level pulse with a pulse width of 2PW and a high level pulse with a pulse width of 2PW connected in sequence. Furthermore, M unit high level pulses and N unit low level pulses can be added to the second signal to generate the first signal. Fig.11 As shown in the figure, the pulse width of the unit high / low level pulse is PW, M=1, N=0. Fig.11 As shown in the second signal in the indicator box 111 in , M=1 unit high level pulses are all located before the second signal, and the high level ratio of the first signal is 3 / 5. Or, as Fig.11 As shown in the second signal in the indicator box 112 in , M=1 unit high level pulses are all located in the second signal, and the high level ratio of the first signal is 3 / 5. Or, as Fig.11As shown by the second signal in the indicator box 113 in FIG. 1 , all of the M=1 unit high-level pulses are located after the second signal, and the high-level ratio of the first signal is 3 / 5.

[0116] Example 7, K=1, a signal sequence with a length of K generates a second signal in a preset mapping manner, and different width ratios of two high-level pulses in the second signal correspond to different information sequences. Fig.12 As shown, when the bit value of the signal sequence is 0, the ratio of the first high-level pulse width to the second high-level pulse width in the second signal is less than 1. When the bit value of the signal sequence is 1, the ratio of the first high-level pulse width to the second high-level pulse width in the second signal is greater than 1. Further, the first signal can be generated based on the second signal and the other M unit high-level pulses and N unit low-level pulses. Fig.13 As shown in the figure, the pulse width of the unit high / low level pulse is PW, M=2, N=0. Fig.13 As shown in the second signal in the indicator box 131 in , M=2 unit high level pulses are all located within the last low level pulse in the second signal, and the high level ratio of the first signal is 5 / 8.

[0117] In some embodiments, the value of K may be greater than 1. In addition, the following uses Examples 8 to 11 to exemplarily illustrate the situation in which the value of K in this embodiment is greater than 1.

[0118] Example 8: Fig.14 As shown, K=2, M=2, N=0, the bit value of the information sequence may include 00, 01, 10 or 11, and the second signal is determined based on the information sequence and the Manchester waveform coding with a rate of 1 / 2. In addition, different combinations of high-level pulses and low-level pulses in the second signal correspond to different information sequences. Then, M=2 unit high-level pulses can be added to the second signal to generate the first signal. Fig.14 As shown, M=2 unit high-level pulses can be divided into two parts, one part is located before the second signal, and the other part is located after the second signal, and the high level accounts for 2 / 3 of the first signal.

[0119] Example 9: Fig.15 As shown, K=2, M=2, N=0. The second signal is determined based on the information sequence and the preset mapping method. In addition, different width combinations of high-level pulses and low-level pulses in the second signal correspond to different information sequences. Furthermore, the first signal can be composed of the second signal and another M=2 unit high-level pulses, such as Fig.15 As shown, M=2 unit high-level pulses are all located after the second signal, and the high level accounts for 3 / 5 in the first signal.

[0120] Example 10: Fig.16 As shown, K=2, M=2, N=0. The second signal is determined based on the information sequence and the preset mapping method. In addition, different width combinations of high-level pulses and low-level pulses in the second signal correspond to different information sequences. Furthermore, the first signal can be composed of the second signal and another M=2 unit high-level pulses, such as Fig.16 As shown, M=2 unit high level pulses are divided into two parts, each including 1 unit high level pulse, one part is located before the second signal, and the other part is located after the second signal. And the high level accounts for 5 / 8 in the first signal.

[0121] Example 11: Fig.17 As shown, K=2, M=2, N=1. The second signal is determined based on the information sequence and the pre-set mapping method. In addition, different width combinations of high-level pulses and low-level pulses in the second signal correspond to different information sequences. Furthermore, the first signal can be composed of the second signal and another M=2 unit high-level pulses and N=1 unit low-level, such as Fig.17 As shown, M=2 unit high level pulses and N=1 unit low level pulses are all located after the second signal. In addition, the high level accounts for 15 / 22 in the first signal. In addition, M=2 unit high level pulses and N=1 unit low level pulses can also be all located before or in the middle of the second signal, or divided into multiple parts, respectively located before, in the middle or after the second signal, which will not be repeated here.

[0122] In some embodiments, for different information sequences, the lengths of the corresponding generated second signals may also be different. In addition, the present embodiment is exemplarily described below with reference to Examples 12 and 13.

[0123] Example 12: Fig.18 As shown, K=1, and the second signal is determined based on the information sequence through a pre-set mapping method. The bit value of the information sequence is 0, and the corresponding second signal can be as shown in the indicator box 181. The bit value of the information sequence is 1, and the corresponding second signal can be as shown in the indicator box 182. It can be seen that the signal length in the indicator box 181 is different from the signal length in the indicator box 182. That is, for different information sequences, the length of the corresponding generated second signal may also be different. Furthermore, M=1, N=0. The first signal can be composed of the second signal and another M=1 unit high-level pulses, such as Fig.18 As shown, M=1 unit high level pulse is located before the second signal. In addition, the high level accounts for 2 / 3 of the first signal.

[0124] Example 13: Fig.19As shown, K = 2, and the second signal is determined based on the information sequence through a preset mapping method. The high-level pulses in the second signal are determined based on the bit values of the information sequence. For example, the width of the i-th high-level pulse in the second signal is determined by the value of the i-th bit in the information sequence, where 0 ≤ i < k. Exemplarily, when the i-th bit in the information sequence is 1, the width of the i-th high-level pulse in the second signal is 2PW. When the i-th bit in the information sequence is 0, the width of the i-th high-level pulse in the second signal is PW. In addition, the width of the low-level pulses in the second signal is PW. Thus, when the bit values of the information sequence are 00, the corresponding second signal can be as shown in indication box 191; when the bit values of the information sequence are 01, the corresponding second signal can be as shown in indication box 192; when the bit values of the information sequence are 10, the corresponding second signal can be as shown in indication box 193; when the bit values of the information sequence are 11, the corresponding second signal can be as shown in indication box 194. It can be seen that the signal length in indication box 191 is different from the signal lengths in indication box 192 and indication box 193, the signal length in indication box 194 is also different from the signal lengths in indication box 192 and indication box 193, and the signal length in indication box 191 is also different from the signal length in indication box 194. That is, for different information sequences, the lengths of the corresponding generated second signals can also be different. Furthermore, M = 2, N = 1. The first signal can be composed of the second signal, another M = 2 unit high-level pulses, and N = 1 unit low level, as Fig.19 shown, M = 2 unit high-level pulses and N = 1 unit low level are both located after the second signal. And, the high-level ratio of the first signal is 5 / 8.

[0125] In some embodiments, the pulse widths PW of the other M unit high-level pulses and N unit low-level pulses in the first signal are less than or equal to the high / low level pulse widths in the second signal. Or, the pulse widths PW of the other M unit high-level pulses and N unit low-level pulses in the first signal are greater than the high / low level pulse widths in the second signal. And, the following uses Example 14 - Example 16 to give an exemplary description of this embodiment.

[0126] Example 14: K = 1, M = 1, N = 0. The second signal is determined by the information sequence and Manchester waveform coding with a rate of 1 / 2. Different combination orders of high-level pulses and low-level pulses in the second signal correspond to different information sequences. As Fig. 20As shown, when the bit value of the signal sequence is 0, the second signal is composed of a low-level pulse and a high-level pulse with a pulse width of PW'. Alternatively, when the bit value of the signal sequence is 1, the second signal is composed of a low-level pulse and a high-level pulse with a pulse width of PW'. Further, the first signal is based on the second signal and another M=1 unit high-level pulse. In addition, the width of M=1 unit high-level pulse is PW, and PW>PW'. Wherein, as shown in the second signal in the indication box 201, M=1 unit high-level pulses are all located before the second signal, and the high-level ratio of the first signal is (PW+PW') / (PW+2PW')>2 / 3. Alternatively, as shown in the second signal in the indication box 202, M=1 unit high-level pulses are all located in the second signal, and the high-level ratio of the first signal is (PW+PW') / (PW+2PW')>2 / 3. Alternatively, as shown by the second signal in the indication box 203, M=1 unit high level pulses are all located after the second signal, and the high level ratio of the first signal is (PW+PW') / (PW+2PW')>2 / 3.

[0127] Example 15, K=1, M=1, N=0. The second signal is determined by the information sequence and the preset mapping method, and different combinations of high-level pulses and low-level pulses in the second signal correspond to different information sequences. Fig.21 As shown, when the bit value of the signal sequence is 0, the second signal is composed of a low-level pulse with a pulse width of PW', a high-level pulse with a width of 2PW', and a low-level pulse with a width of PW'. Alternatively, when the bit value of the signal sequence is 1, the second signal is composed of a high-level pulse with a pulse width of PW', a low-level pulse with a width of 2PW', and a high-level pulse with a width of PW'. Further, the first signal is based on the second signal and another M = 1 unit high-level pulse. As Fig. 22 As shown, M=1 unit high level pulses are all located before the second signal, and the high level ratio of the first signal is (PW+2PW') / (PW+4PW').

[0128] Example 16: K = 2, M = 2, N = 1. The second signal is determined by the information sequence and a preset mapping method. Different combinations and orders of high-level pulses and low-level pulses in the second signal correspond to different information sequences. Moreover, different pulse widths of different high-level pulses in the second signal correspond to different bit values. That is, the width of the i-th high-level pulse in the second signal is determined by the value of the i-th bit in the information sequence, where 0 ≤ i < k. Exemplarily, when the i-th bit in the information sequence is 1, the width of the i-th high-level pulse in the second signal is PW2; when the i-th bit in the information sequence is 0, the width of the i-th high-level pulse in the second signal is PW1. The width of the low-level pulse in the second signal is PW0, where PW2 > PW1 ≥ PW0. Further, the first signal is composed of the second signal, along with another M = 2 unit high-level pulses and N = 1 unit low-level pulse. As Fig.23 shown, the M = 2 unit high-level pulses and N = 1 unit low-level pulse are located after the second signal. And the high-level ratio of the first signal is (PW1 + PW2 + 2PW) / (PW1 + PW2 + 2PW0 + 3PW).

[0129] In some embodiments, the bit length of the information sequence is K, and there can be 2 k kinds of bit values, which can also be understood as including 2 k kinds of information sequences. The 2 k kinds of information sequences can correspondingly generate 2 k kinds of second signals. Further, the 2 k kinds of second signals are combined with another M high-level pulses and N low-level pulses to generate 2 k kinds of first signals. Among them, in the 2 k kinds of first signals, the M unit high-level pulses and N unit low-level pulses are located at the same position of the second signal. For example, both the M unit high-level pulses and N unit low-level pulses are located before the first pulse of the second signal, or both the M unit high-level pulses and N unit low-level pulses are located after the last pulse of the second signal, etc., and will not be listed one by one.

[0130] Alternatively, in some embodiments, among the 2 k kinds of first signals, the M unit high-level pulses and N unit low-level pulses can be located at different positions of the second signal. And the following uses Example 17 - Example 18 to give an exemplary description of this embodiment.

[0131] Example 17: K = 1. The second signal is determined by the information sequence and a preset mapping method. Different width ratios of two high-level pulses in the second signal correspond to different information sequences. As Fig.24As shown, the bit value of the information sequence is 0, and the ratio of the first high-level pulse width to the second high-level pulse width of the second signal is less than 1. Alternatively, the bit value of the information sequence is 1, and the ratio of the first high-level pulse width to the second high-level pulse width of the second signal is greater than 1.

[0132] Furthermore, the first signal is composed based on the second signal and another M unit high level pulses and N unit low level pulses, wherein the pulse width of the unit high / low level pulse is PW, which can be determined by presetting or by signaling configuration, wherein M≥1, N≥0 and M>N.

In addition, the high level accounts for 2 / 3 in the first signal.

[0134] Or, if Fig.25B As shown, M=2, N=0, K=1.

In addition, the high level ratio in the first signal is 5 / 7.

[0135] Or, if Fig.25C As shown, M=3, N=0, K=1. The bit value of the information sequence is 0. In the first signal, 1 high-level pulse is located after the first high-level pulse in the second signal, and 2 high-level pulses are located after the second high-level pulse in the second signal. Alternatively, the bit value of the information sequence is 1. In the first signal, 2 high-level pulses are located after the first high-level pulse in the second signal, and 1 high-level pulse is located after the second high-level pulse in the second signal. In addition, the high level accounts for 3 / 4 in the first signal.

[0136] Or, if Fig.25DAs shown, M=6, N=0, K=1. The bit value of the information sequence is 0. In the first signal, 2 high-level pulses are located after the first high-level pulse in the second signal, and 4 high-level pulses are located after the second high-level pulse in the second signal. Alternatively, the bit value of the information sequence is 1. In the first signal, 4 high-level pulses are located after the first high-level pulse in the second signal, and 2 high-level pulses are located after the second high-level pulse in the second signal. In addition, the high level ratio in the first signal is 9 / 11.

In addition, the high level ratio in the first signal is 5 / 9.

[0138] Or, if Fig.25F As shown, M=3, N=2, K=1. The bit value of the information sequence is 0. For M=3 unit high-level pulses and N=2 unit low-level pulses, in the first signal, a sequential combination of 1 unit high-level pulse and 1 unit low-level pulse is located after the first high-level pulse in its second signal, and a sequential combination of 2 unit high-level pulses and 1 unit low-level pulse is located after the second high-level pulse in its second signal.

[0142] In another possible implementation, a first bit sequence may be generated first, and then a second bit sequence may be generated based on the first bit sequence, and then the first signal may be determined based on the second bit sequence. Fig.28 As shown, it can be specifically implemented as the following steps S101B1-S101B3:

[0151] In some embodiments, the first signal is generated based on the second bit sequence through a preset waveform encoding method or mapping method.

[0152] In some embodiments, the high level pulse and the low level pulse in the first signal correspond to one or more modulation symbols of the same length and different amplitude values, and the different amplitudes of the modulation symbols or the presence or absence of data transmission of the modulation symbols correspond to the high level pulse and the low level pulse, respectively. Exemplarily, the modulation symbol can be, for example, an on-off keying modulation symbol, an amplitude shift keying modulation symbol, an orthogonal frequency division multiplexing modulation symbol, etc., and the length of the modulation symbol is the duration of the symbol.

[0153] In some embodiments, the length of the first signal is determined based on the duration of the first signal. The duration of the pulse of the first signal is determined based on the pulse width of the high level pulse and the pulse width of the low level pulse in the first signal.

[0154] In some embodiments, an information sequence with a length of K=1 is mapped to obtain a first bit sequence in a predetermined encoding method or mapping method, and P bits are added to the first bit sequence to generate a second bit sequence, where P is a positive integer. Further, a first signal is generated based on the second bit sequence, where different combinations of high-level pulses and low-level pulses in the first signal correspond to different second bit sequences. The following is an exemplary description of this embodiment with Examples 19 to 25.

[0204] In some embodiments, for different information sequences, the lengths of the corresponding generated first bit sequences may also be different. In addition, the present embodiment is exemplarily described below with examples 30 and 31.

[0205] Example 30, K=1, and the information sequence of K=1 is determined based on a preset mapping method to determine the first bit sequence, and the value of K1 can be 4, 6 or other possible values. Then the first bit sequence and another P=1 bit are combined into a second bit sequence, where the P=1 bit sequence is 1. The P=1 bit can be all located before, in the middle or after the first bit sequence, or divided into multiple parts and respectively located before, in the middle or after the first bit sequence. The first bit sequence and the second bit sequence are shown in Table 12. Taking P=1 bit all located before the first bit sequence as an example, the bit value of the information sequence is 0, the value of the first bit sequence is 1001, and the value of the second bit sequence is 11001.

[0211] In some embodiments, in the process of generating the first signal based on the second bit sequence through a preset waveform encoding method or mapping method, the waveform width corresponding to the first bit sequence is the same as the waveform width corresponding to the other P bits.

[0212] In some embodiments, the waveform width corresponding to the first bit sequence may be different from the waveform width corresponding to the other P bits. In addition, the present embodiment is exemplarily described below with examples 32 to 34.

[0213] Example 32, K=1, K1=2, the first bit sequence and another P=1 bit constitute the second bit sequence, where the P=1 bit sequence is 1. The P=1 bit can all be located before, within, or after the first bit sequence, and the first signal is obtained by mapping the second bit sequence in a predetermined mapping manner. The P=1 bit in the second bit sequence is mapped to a high-level pulse with a width of PW, bit 1 belonging to the first bit sequence in the second bit sequence is mapped to a high-level pulse with a width of PW', and bit 0 belonging to the first bit sequence is mapped to a low-level pulse with a width of PW', where PW>PW'. The first bit sequence and the second bit sequence are as shown in Table 1. When the bit value of the information sequence is 0 and the value of the first bit sequence is 01, and further, P=1 bit is all located before the first bit sequence, the value of the second bit sequence is 101, or, when P=1 bit is all located in the first bit sequence, the value of the second bit sequence is 011, or, when P=1 bit is all located after the first bit sequence, the value of the second bit sequence is 011. Alternatively, when the bit value of the information sequence is 1 and the value of the first bit sequence is 10, and further, P=1 bit is all located before the first bit sequence, the value of the second bit sequence is 110, or, when P=1 bit is all located in the first bit sequence, the value of the second bit sequence is 110, or, when P=1 bit is all located after the first bit sequence, the value of the second bit sequence is 101. In addition, the first signal obtained based on the second bit sequence can be as described above. Fig. 20 shown.

[0214] Example 33, K=1, K1=4, the first bit sequence and another P=1 bit constitute the second bit sequence, where the P=1 bit sequence is 1. Taking the case where all P=1 bits are located before the first bit sequence as an example, the first signal is obtained by mapping based on the second bit sequence in a pre-set mapping manner. The P=1 bit in the second bit sequence is mapped to a high-level pulse with a width of PW, bit 1 belonging to the first bit sequence in the second bit sequence is mapped to a high-level pulse with a width of PW', and bit 0 belonging to the first bit sequence is mapped to a low-level pulse with a width of PW', where PW>PW'. Among them, the first bit sequence and the second bit sequence are shown in Table 14. Taking the case where all P=1 bits are located before the first bit sequence as an example, the bit value of the information bit is 0, the bit value of the first bit sequence is 1001, and the bit value of the second bit sequence is 11001. Alternatively, the bit value of the information bit is 1, the bit value of the first bit sequence is 0110, and the bit value of the second bit sequence is 10110.

Taking the case where all P=3 bits are located after the first bit sequence as an example, the first signal is obtained by mapping based on the second bit sequence in a pre-set mapping manner. Bit 1 among the P=3 bits in the second bit sequence is mapped to a high-level pulse with a width of PW, and bit 0 among the P=3 bits is mapped to a low-level pulse with a width of PW. Bit 0 belonging to the first bit sequence in the second bit sequence is mapped to a low-level pulse with a width of PW0, a single bit 1 belonging to the first bit sequence is mapped to a high-level pulse with a width of PW1, and two consecutive bit 1s belonging to the first bit sequence are jointly mapped to a high-level pulse with a width of PW2, where PW>PW2>PW1≥PW0.

[0236] S102. Send a first signal.

[0237] Correspondingly, after receiving the first signal, the receiving end can use the high level in the signal for charging, and at the same time use the part of the first signal belonging to the second signal or the first bit sequence to detect the information bits represented in the received signal.

[0238] It should be noted that Figure 1 Taking the system shown in the figure as an example, the information transmission method used by the reader to tag link is the pulse interval encoding (PIE) scheme. Fig.29As shown, the transmission signal corresponding to the bit value of 0 is composed of high-level pulses and low-level pulses of equal width, and the width of the low-level pulse can be PW (Pulse Width). The transmission signal corresponding to the bit value of 1 is composed of high-level pulses and low-level pulses of unequal widths, where the width of the low-level pulse is PW, and the width of the high-level pulse can be 2PW~3PW. In the case of bit 0 and bit 1 being equal, the high-level ratio of each transmission signal is 3 / 5~2 / 3. Using the different width characteristics of the high-level pulses in the transmission signals of bit 0 and bit 1, the passive tag can make bit decisions based on the received high-level pulse width. In addition, since there are high-level pulses in the transmission signals of bit 0 and bit 1, the RF signal sent by the reader can always maintain a certain amount of energy.

[0239] For example, the waveform length of bit 0 is T s =2PW, the width of high level pulse and low level pulse are both 0.5T s =PW, so the waveform length of bit 1 is (1+α)T s (0.5≤α≤1). The amplitude of the high level is A, and the amplitude of the low level is 0, so the transmission signal of bit 0 has energy The transmitted signal of bit 1 has energy E1 = A 2 (1+α-0.5)T s Furthermore, when the probability of bits 0 and 1 is equal, the transmitted signal per bit has an average energy of Therefore, this information transmission method can ensure that energy is provided to the passive tag while data is transmitted.

[0240] Furthermore, in PIE coding, the average length of the transmission signal per bit is Therefore, within the length range of each transmission signal, the average power consumption of each bit of the transmission signal is It is easy to know that this value is proportional to the high level ratio in each transmission signal in PIE coding. Therefore, in the present disclosure, the energy supply capacity of the information transmission method can be improved to a certain extent by changing the high level ratio in the first signal.

[0241] Based on the technical solution provided by the present disclosure, a signal generated based on an information sequence can be sent to generate a signal composed of a high-level pulse and a low-level pulse. Based on the signal, energy can be provided to a passive terminal at the receiving end while transmitting information. In addition, the different ratios of high-level pulses and low-level pulses in the signal can be used to measure the energy supply capacity of the signal, thereby improving the energy supply capacity by controlling the ratio of high-level pulses and low-level pulses in the signal.
