The essence of passive IoT is that it does not require a built-in power supply and can be operated by obtaining energy from external sources (such as readers), so that the device can work without batteries.

[0041] 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.

[0042] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and other forms thereof, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open, inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" and the like are intended to indicate that specific features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0043] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0044] In the embodiments of 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 embodiments of 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.

[0045] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values ​​may, in practice, be based on additional conditions or values ​​beyond those stated.

[0046] At present, as a highly integrated and comprehensive application of the new generation of information technology, the application of the Internet of Things is becoming more and more extensive. With the continuous popularization of technologies such as wearable devices, smart homes, smart connected cars, and smart cities, hundreds of billions of devices will be connected to the network, and the application of the Internet of Things will also develop in the direction of ubiquitous popularization. Among them, the passive Internet of Things has gradually become the focus of attention in related fields due to its technical features such as supporting massive device access, low cost, and passiveness.

[0047] Passive IoT devices in the passive IoT do not need to be equipped with batteries, nor do they use wired methods to obtain electricity from the power grid. Instead, they obtain the required energy from the environment to support the perception, computing and wireless transmission of passive IoT devices. However, since passive IoT devices need to collect energy from the environment to maintain operation, the energy supply is relatively limited, so they may not be able to provide enough energy to ensure high sensitivity during data transmission, and the reliability of data transmission is low. In addition, since passive IoT devices need to collect energy from the environment, their performance is easily affected by environmental factors. For example, changes in environmental factors such as light intensity and temperature may affect the energy collection and data transmission performance of the device. In addition, in order to achieve energy saving and extend service life, passive IoT devices usually adopt low-power design, which may limit the receiving power and receiving sensitivity of passive IoT devices when receiving data.

[0048] In addition, in the communication system, the transmitting end can perform channel coding on the first data sequence to obtain a coded data sequence, then map the coded data sequence to a constellation modulation symbol, and finally send the obtained constellation modulation symbol based on the channel. In the process of data transmission based on the channel, factors such as multipath, mobility, noise and interference may cause data transmission distortion, and the channel coding method of forward error correction (FEC) coding can be used to improve the reliability and efficiency of data transmission. In particular, the forward error correction coding adds some redundant information to the transmitted data sequence (such as the first data sequence) so that the receiving end can reliably restore the original information data sequence according to the corresponding forward error correction coding principle.

[0049] Taking the forward error correction coding as convolution coding as an example, a simple explanation is given. Convolution coding can introduce redundant bits into the input information bits so that the encoded data sequence has a certain error correction capability. For example, the current output codeword can be obtained by weighted summing the first N input codewords and the current output codeword according to a certain ratio. Therefore, each output codeword is not only related to the current input codeword, but also to some previous input codewords. In order to reduce the performance loss caused by burst interference, traditional convolution coding schemes usually add modules such as sub-block interleaving, bit collection and bit selection. For example, in the fourth generation mobile communication, the control channel uses convolution coding with a constraint length of 7 and is implemented by 3 component codes. The data sequence output by each component code can be sub-block interleaved, and then the interleaved data sequence can be bit collected, that is, the interleaved data sequence is stored in the circular buffer in sequence, and finally the output data sequence of the corresponding length is obtained by the bit selection method. Among them, the interleaving operation can make the coded bits of the convolution codeword belonging to the same grid as much as possible dispersed, thereby improving the ability to resist sudden fading and interference of the channel.

[0050] However, for passive IoT devices, it is crucial to keep the device simple and minimize energy consumption. The operations of sub-block interleaving, bit collection, and bit selection in traditional convolutional coding schemes increase the complexity of hardware and may cause additional energy consumption, which is very disadvantageous for resource-constrained passive IoT devices such as tag devices. It can be seen that passive IoT devices cannot use traditional convolutional coding to improve the ability to resist sudden fading and interference of the channel, so their data transmission performance is low.

[0051] In summary, how to improve the data transmission performance based on passive Internet of Things is a technical problem that needs to be solved urgently in related fields.

[0052] In view of this, the present disclosure provides a data transmission method, which can perform encoding processing, repetition processing, frequency hopping processing, etc. on a data sequence to be transmitted, and then transmit the processed data sequence. Among them, encoding processing can improve the transmission reliability of data, and repetition processing can adopt a continuous retransmission method when the transmission environment is unstable or the communication distance is far, thereby improving the transmission reliability of data, reducing the bit error rate and thus improving the sensitivity of receiving the data. Frequency hopping processing can make the carrier frequency of the transmission signal discretely change according to a predetermined rule through spread spectrum, thereby improving the anti-interference and confidentiality of communication. Therefore, based on this technical solution, the data transmission performance based on passive Internet of Things can be improved.

[0053] The data transmission method provided in the present disclosure can be applied to various communication systems, for example, it can be the Internet of Things (IoT), narrowband Internet of Things (NB-IoT), long term evolution (LTE), the fifth generation (5G) communication system, it can also be a hybrid architecture of LTE and 5G, it can also be a new communication system that will appear in 6G or future communication development, etc. The communication system can also be a machine to machine (M2M) network, machine type communication (MTC) or other networks. The communication system can also be a passive Internet of Things network communication system.

[0054] In some embodiments, the data transmission method provided by the embodiments of the present disclosure can be applied to a communication system including a reader and a tag.

[0055] Figure 1 The following is a schematic diagram of the architecture of a passive Internet of Things system provided by the present disclosure. Figure 1 As shown, the passive Internet of Things system 100 may include an excitation source (helper) 101 , a reader / writer 102 , and a tag 103 .

[0056] The excitation source 101 is an available ambient RF source, such as a broadcast television signal transmission tower, a mobile communication system base station, and a wireless fidelity (Wi-Fi) access point, etc., and the present disclosure does not limit its specific form. In some embodiments, the excitation source 101 can send a wireless RF signal within the communication frequency range.

[0057] The reader 102 , which may also be called a reader, may also be a node (Node) or an intermediate user equipment (Intermediate UE) in the network. The reader 102 may be used to send radio frequency energy to activate the tag 103 , and to receive and analyze data transmitted by the tag 103 .

[0058] The tag 103 can be used to identify and transmit data. In some embodiments, the tag 103 can be a passive tag that can collect energy through backscattering technology to send and receive messages. Exemplarily, the tag 103 can be radio frequency identification (RFID), Bluetooth, Zigbee, etc. When charging is required, the tag 103 can receive a carrier wave for energy harvesting (CW for EH) sent by the reader 102 to obtain the energy required for receiving and sending signals.

[0059] In some embodiments, during the data transmission process from the tag 103 to the reader / writer 102, the tag 103 may also be referred to as a transmitter, and the reader / writer 102 may be referred to as a receiver.

[0060] In some embodiments, tag 103 may also be referred to as a terminal, such as an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a wireless communication device, etc. The terminal may also be a passive Internet of Things terminal or a passive Internet of Things device.

[0062] Device type I: It can also be expressed as Device 1, and this type of device can also be referred to as the first device in this disclosure. The device corresponding to the first device is a passive device, without energy storage devices, and the peak power consumption is about 1 microwatt. In addition, the first device does not have downlink and uplink amplification functions, and the uplink transmission of the first device is achieved by backscattering the carrier provided externally. The device corresponding to the first device can also be a low-rate device or a low-coverage device.

[0063] Device Type II: It can also be expressed as Device 2a. This type of device may also be referred to as the second device in this disclosure. The second device is a semi-active device with a small amount of energy storage devices and a peak power consumption of approximately several hundred microwatts. In addition, the second device may include downlink and / or uplink amplification functions. Although the device may have an amplification function inside, the uplink signal is still sent via backscattering, but the second device can send a signal from the device (Device) to the reader (Reader) (Device-to-Reader, D2R) by backscattering. The device corresponding to the second device may also be a medium-rate device or a medium-coverage device.

[0064] Device Type III: It can also be expressed as Device 2b. This type of device may also be referred to as a third device in this disclosure. The device corresponding to the third device is an active device with an energy storage device and a peak power consumption of about several hundred microwatts. In addition, the third device may include downlink and / or uplink amplification functions. The uplink transmission of the third device is generated autonomously by the device itself, that is, the device can generate and send D2R signals autonomously without relying on an external carrier for backscattering. The device corresponding to the third device may also be a high-speed device or a device with a large coverage.

[0065] It should be noted that the high rate, medium rate, and low rate mentioned above refer to the relative values ​​of the rates supported by the three types of devices. In addition, the low coverage, medium coverage, and high coverage mentioned above refer to the relative values ​​of the coverage ranges supported by the three types of devices.

When the coding method in the coding information is a convolutional coding method, the value range of the coding rate includes at least one of the following: 1 / 4, 1 / 3, 1 / 2 and 2 / 3.

[0097] In some embodiments, the line code encoding method includes at least one of the following: Manchester encoding, Miller encoding, FMO encoding, first line code encoding, and second line code encoding.

[0098] For example, the following describes each line code encoding method:

[0099] Manchester Code

[0100] Manchester coding can also be called self-synchronization code or phase coding. It can maintain synchronization between the sending device and the receiving device through the jump of the signal level. The rules of Manchester coding are as follows:

[0101] At the middle of each bit period, the signal will have a transition.

[0102] Bit 0 starts with a high-to-low transition and then remains at a low level until the end of the bit period (the output sequence is [1 0]).

[0103] Bit 1 starts with a low-to-high transition and then maintains a high level until the end of the bit period (the output sequence is [0 1]).

[0104] Exemplarily, the code rate of Manchester encoding is 1 / 2, and each time 1 bit is input, 2 bits can be encoded and output. For example, if the input data sequence is [1 0 1 1], then according to the rule of Manchester encoding, the output Manchester encoding sequence is [0 1 1 0 0 1 1 0], [1 0 0 1 1 0 1 0].

[0105] In some embodiments, the code rate of Manchester coding can also be 1 / 4, and 1 bit is input each time, and 4 bits can be encoded and output. For example, the output sequence is [1 0 1 0] to represent bit 1, and the output sequence is [0 1 0 1] to represent bit 0. Alternatively, the output sequence is [1 0 1 0] to represent bit 0, and the output sequence is [0 1 0 1] to represent bit 1.

[0106] Alternatively, the code rate of Manchester coding can also be 1 / 6, and 1 bit is input each time, and 6 bits can be encoded and output. For example, the output sequence is [1 0 1 0 1 0] to represent bit 1, and the output sequence is [0 1 01 0 1] to represent bit 0. Alternatively, the output sequence is [1 0 1 0 1 0] to represent bit 0, and the output sequence is [01 0 1 0 1] to represent bit 1.

[0107] Alternatively, the code rate of Manchester coding can also be 1 / 8, and 8 bits can be encoded and output each time 1 bit is input. For example, the output sequence is [1 0 1 0 1 0 1 0] to represent bit 1, and the output sequence is [0 1 0 1 0 1 0 1] to represent bit 0. Alternatively, the output sequence is [1 0 1 0 1 0 1 0] to represent bit 0, and the output sequence is [0 1 0 1 0 1 0 1] to represent bit 1.

[0108] In some embodiments, the code rate of Manchester coding can also be 1 / z, and each time 1 bit is input, z bits can be encoded and output. Among them, Z can be an even number greater than 0, for example, the value of Z can be 8, 10, 12, 14, 16, 18, 20, 22, 24, etc. In addition, when the input bit is 1, the corresponding output sequence is a sequence obtained by repeating [1 0] z / 2 times, and when the input bit is 0, the corresponding output sequence is a sequence obtained by repeating [0 1] z / 2 times. Alternatively, when the input bit is 0, the corresponding output sequence is a sequence obtained by repeating

[10] z / 2 times, and when the input bit is 1, the corresponding output sequence is a sequence obtained by repeating [0 1] z / 2 times.

[0109] Miller coding

[0110] Miller coding is a line coding technology used in serial communication. It represents the logic value of the corresponding bit by changing the level in the bit window. If the logic information to be sent is "1", the level flip occurs in the middle position of the bit window. If the logic information to be sent is "0", the level flip does not occur in the middle position of the bit window. The starting position of the bit window with the logic information of "1" does not flip. The starting position of the bit window with the logic information of "0" usually does not flip, but when the logic information of two consecutive bit windows is "0", the starting position of the second "0" bit window will flip to provide synchronization information. Exemplarily, assuming that the input data sequence is X = [1 0 0 01 1 1 0], the line coded sequence obtained by using Miller coding on the input data sequence is Y = [1 00 0 1 1 0 0 0 1 1 0 0 1 1 1].

[0111] In addition, Miller coding may be M-order subcarrier Miller coding. In M-order subcarrier Miller coding, each bit window duration includes M subcarrier periods. Exemplarily, the value of M may include at least one of the following: 1, 2, 4, 8, 16, 32, 48, 64, 96, and 128.

[0112] Among them, when using Miller coding of M-order subcarriers, the parameter M can indeed be used to mark the change of the subcarrier frequency or data rate of Miller coding. Since the duration of each bit window remains unchanged, but the bit window is subdivided into more subcarrier periods, the data rate will be reduced accordingly. Specifically, the data rate will be reduced to 1 / M of the original. For example, if M is equal to 2, that is, each bit window contains two subcarrier periods, then the data rate will be reduced to 1 / 2 of the original data rate. When M is greater than 1, Miller coding of M-order subcarriers is actually the result of multiplying the coded data sequence output by the 1st-order Miller coding with the subcarrier signal. Exemplarily, the input data sequence is X=[1 0 0 0 1 11 0], then second-order subcarrier Miller coding is used for the first data sequence, and the obtained line-coded sequence is Y=[1 0 0 1 0 1 0 1 1 0 10 0 1 0 1 0 1 1 0 1 0 0 1 0 1 1 0 1 0 10].

[0113] Dual-phase space coding

[0114] In the two-phase space number coding, the logic information of the corresponding bit can be represented by the level change in a bit window, and the starting position of each bit window will always flip. After the starting position of the bit window flips, the level in the bit window remains unchanged, that is, there is no flip in the middle, then the logic information corresponding to the bit window is "1". After the starting position of the bit window flips, it flips again in the middle position of the bit window, then the logic information corresponding to the bit window is "0".

[0115] Exemplarily, assuming that the input data sequence is X=[1 0 0 0 1 1 0 0], after the input data sequence is processed by bi-phase space coding, the obtained line coded sequence is Y=[0 0 1 0 1 0 1 0 1 10 0 1 0 10]. Among them, the bit '1' can be considered as a corresponding high-level bit, and the bit '0' can be considered as a corresponding low-level bit.

[0116] First Line Code

[0117] The first line code encoding is used to indicate that 1 bit is converted into multiple bits, or that the bit with a value of 0 in the multiple bits is converted into a low level and the bit with a value of 1 in the multiple bits is converted into a high level, or that the bit with a value of 0 in the multiple bits is converted into a high level and the bit with a value of 1 in the multiple bits is converted into a low level.

[0118] Second line code

[0119] The second line code encoding is used to indicate that 1 bit is converted into multiple bits, or that the bit with a value of 0 in the multiple bits is converted into a negative level and the bit with a value of 1 in the multiple bits is converted into a positive level, or that the bit with a value of 0 in the multiple bits is converted into a positive level and the bit with a value of 1 in the multiple bits is converted into a negative level.

[0252] Based on the technical solution provided by the present disclosure, the data sequence to be transmitted can be subjected to encoding processing, repetition processing, frequency hopping processing, etc., and then the processed data sequence can be transmitted. Among them, encoding processing can improve the transmission reliability and transmission distance of data, and repetition processing can adopt a continuous retransmission method when the transmission environment is unstable or the communication distance is long, thereby improving the transmission reliability of data, reducing the bit error rate and thus improving the sensitivity of receiving the data, and frequency hopping processing can make the carrier frequency of the transmission signal discretely change according to a predetermined rule through spread spectrum, thereby improving the anti-interference and confidentiality of communication. Therefore, based on this technical solution, the data transmission performance based on passive Internet of Things can be improved.

[0253] In some embodiments, the transmitting end may also receive indication information. The indication information includes at least one of the above-mentioned transmission data information, encoding information, repetition information and frequency hopping information. That is, the indication information may be determined based on the above-mentioned first information and / or second information. Exemplarily, the transmitting end may receive indication information, which may include transmission data information. Taking the transmitting end as a passive IoT device as an example, the passive IoT device may receive the indication information sent by the reader / writer, and then perform at least one of encoding processing, repetition processing and frequency hopping processing on the first data sequence based on the indication information.

[0254] In one example, the indication information includes a coding mode, a coding rate, a repetition number, a carrier number, and a frequency hopping number. For example, the coding mode includes a convolutional coding mode and a binary phase shift keying modulation mode.

[0255] At this time, if Figure 3 As shown, the transmitting end can perform coding and modulation processing on the first data sequence based on the indication information, such as convolution coding processing and binary phase shift keying modulation processing, to obtain a coded data sequence.

[0256] The code rates used in convolutional coding include 1 / 2, 1 / 3, and 1 / 4. The code rate is 1 / 2, and the input bit is b 0 , the output is c 0 , c 1 The code rate is 1 / 3 and the input bit is b 0 , the output is c 0 , c 1 , c 2 The code rate is 1 / 4 and the input bit is b 0 , b 1 , the output is c 0 , c 1 , c 2 c 3 Furthermore, the constraint length of the convolutional coding may be 3 to 9, such as 3, 6, 7, 8. The binary phase shift keying modulation mode may be π / 2 offset binary phase shift keying modulation or π / 4 offset binary phase shift keying modulation.

[0257] Furthermore, the transmitting end may also repeatedly process the coded data sequence based on the indication information. Figure 3 As shown, a second data sequence can be obtained after repeated processing.

[0258] The transmitting end may repeatedly process each bit in the coded data sequence, or repeatedly process the entire coded data sequence, and the number of repetitions may be P, where P is an integer greater than or equal to 1. Then, a second data sequence may be obtained, and the second data sequence may be transmitted on different carriers according to the carrier information.

[0259] For example, when the value of the number of repetitions P is 2, the first data sequence is b 0 b 1 b 2 b 3 b 4 b 5 b 6 b 7 The code rate of the convolutional coding is 1 / 2. After the first data sequence is processed by convolutional coding and binary phase shift keying modulation, the coded data sequence is obtained.

[0260] c 0,1 c 0,2 c 1,1 c 1,2 c 2,1 c2,2 c 3,1 c 3,2 c 4,1 c 4,2 c 5,1 c 5,2 c 6,1 c 6,2 c 7,1 c 7,2 Among them, bit bi can be coded and modulated to get c i,1 c i,2 , i = 0, 1, ..., 7, and the length of the encoded data sequence is N 1 =16. If each bit in the coded data sequence is repeatedly processed, the second data sequence can be obtained

[0261] c 0,1 c 0,1 c 0,2 c 0,2 c 1,1 c 1,1 c 1,2 c 1,2 c 2,1 c 2,1 c 2,2 c 2,2 c 3,1 c 3,1 c 3,2 c 3,2 c 4,1 c 4,1 c 4,2 c 4,2 c 5,1 c 5,1 c 5, 2 c 5,2 c 6,1 c 6,1 c 6,2 c 6,2 c 7,1 c 7,1 c 7,2 c 7,2 , the second data sequence length N 2 =32. Thus, the second data sequence can be sent to the receiving end, and the receiving end can perform deduplication processing on the second data sequence based on the indication information to obtain the above-mentioned coded data sequence, and then perform convolution decoding processing on the coded data sequence to obtain the first data sequence.

[0262] For example, when the number of repetitions P is 2, the first data sequence is b 0 b 1 b 2 b 3 b 4 b 5 b 6b 7 The code rate of the convolutional coding is 1 / 2. After the first data sequence is processed by convolutional coding and binary phase shift keying modulation, the coded data sequence is obtained.

[0263] c 0,1 c 0,2 c 1,1 c 1,2 c 2,1 c 2,2 c 3,1 c 3,2 c 4,1 c 4,2 c 5,1 c 5,2 c 6,1 c 6,2 c 7,1 c 7,2 Among them, bit bi can be coded and modulated to get c i,1 c i,2 , i = 0, 1, ..., 8, and the length of the encoded data sequence is N 1 =16. If each bit in the coded data sequence is repeatedly processed, the second data sequence can be obtained

[0264] c 0,1 c 0,2 c 1,1 c 1,2 c 2,1 c 2,2 c 3,1 c 3,2 c 4,1 c 4,2 c 5,1 c 5,2 c 6,1 c 6,2 c 7,1 c 7,2 c 0,1 c 0,2 c 1,1 c 1,2 c 2,1 c 2,2 c 3, 1 c 3,2 c 4,1 c 4,2 c 5 ,1 c 5,2 c 6,1 c 6,2 c 7,1 c 7,2 , the second data sequence length N 2=32. Thus, the second data sequence can be sent to the receiving end, and the receiving end can perform deduplication processing on the second data sequence based on the indication information to obtain the above-mentioned coded data sequence, and then perform convolution decoding processing on the coded data sequence to obtain the first data sequence.

[0265] In some embodiments, the coding information, repetition information, and frequency hopping information in the above indication information may be indicated independently or in combination with the coding information.

[0266] In some embodiments, the indication information may be indicated in a manner corresponding to a control field of a physical random access channel (PRDCH), a data field of a physical channel, a medium access control (MAC) signaling, a configured system information block (SIB information), or predefined configuration information.

[0267] Exemplarily, the coding information of the convolutional coding in the indication information as well as the number of repetitions, the number of carriers, and the number of frequency hopping times may be independently indicated.

[0268] For convolutional coding, 1-bit indication information may be used to indicate convolutional coding. Bit "0" indicates that convolutional coding is disabled, and bit "1" indicates that the code rate of convolutional coding is 1 / 2.

[0269] Alternatively, 1-bit indication information may be used to indicate convolutional coding. Bit "0" indicates that convolutional coding is disabled, and bit "1" indicates that the code rate of convolutional coding is 1 / 3.

[0270] Alternatively, 1-bit indication information may be used to indicate convolutional coding. Bit "0" indicates that convolutional coding is disabled, and bit "1" indicates that the code rate of convolutional coding is 1 / 4.

[0271] Alternatively, 2-bit indication information may be used to indicate convolutional coding. The data sequence "00" indicates that convolutional coding is disabled, the bit "01" indicates that the code rate of convolutional coding is 1 / 2, the data sequence "10" indicates that the code rate of convolutional coding is 1 / 3, and the bit "11" indicates that the code rate of convolutional coding is 1 / 4.

[0272] For the number of repetitions, 3 bits of indication information can be used to indicate the number of repetitions. The data sequence "000" indicates that the number of repetitions is 1, the data sequence "001" indicates that the number of repetitions is 2, the data sequence "010" indicates that the number of repetitions is 4, the data sequence "011" indicates that the number of repetitions is 8, and the data sequence "100" indicates that the number of repetitions is 16.

[0273] For the number of carriers, 1-bit indication information may be used to indicate the number of carriers. Bit "0" indicates that the number of carriers is 1, and bit "1" indicates that the number of carriers is 2.

[0274] For the number of frequency hopping, 1 bit of indication information may be used to indicate the number of frequency hopping. Bit "0" indicates no frequency hopping, and bit "1" indicates frequency hopping, and the number of frequency hopping is 2.

[0275] In some embodiments, the code rate of the convolutional coding and the number of repetitions, the number of carriers, and the number of frequency hopping in the indication information may be jointly coded and indicated. For example, in the case of a single carrier by default, the indication information may be as shown in Table 1.

[0276] Table 1

[0277]

[0278]

[0279] Alternatively, the indication information may be as shown in Table 2.

[0280] Table 2

[0281] codepoint Convolutional coding rate Repetitions 0000 1 / 4 16 0001 1 / 3 16 0010 1 / 4 8 0011 1 / 3 8 0100 1 / 4 4 0101 1 / 3 4 0110 1 / 4 2 0111 1 / 3 2 1000 1 / 2 2 1001 1 / 3 1 1010 1 / 2 1

[0282] Among them, based on the above independent indication, it can be known that the convolutional coding rate can take values ​​of 1 / 4, 1 / 3, 1 / 2, requiring 2 bits of indication information, and the number of repetitions can take values ​​of 1, 2, 4, 8, 16, requiring 3 bits of indication information, and a total of 5 bits of indication information are required. In the case of joint coding indication, only 4 bits of information are required, which saves 1 / 5 of the overhead compared to the 5 bits of information of independent indication. In this way, the overhead of indication information can be saved by means of joint coding indication.

[0283] Alternatively, the code rate and the number of repetitions of the convolutional coding and the number of carriers may also be jointly coded to indicate the indication. The indication information may be as shown in Table 3.

[0284] Table 3

[0285]

[0286]

[0287] Alternatively, the indication information may also be as shown in Table 4.

[0288] Table 4

[0289]

[0290]

[0291] Among them, based on the above independent indication, it can be known that the convolutional coding rate can take values ​​of 1 / 4, 1 / 3, 1 / 2, requiring 2 bits of indication information, the number of repetitions can take values ​​of 1, 2, 4, 8, 16, requiring 3 bits of indication information, the number of carriers can take values ​​of 1, 2, requiring 1 bit of indication information, and a total of 6 bits of indication information are required. In the case of joint coding indication, only 5 bits of information are required, which saves 1 / 6 of the overhead compared to the 6 bits of information of independent indication. In this way, the overhead of indication information can be saved by means of joint coding indication.

[0292] In some embodiments, the frequency hopping mode may include one of the following:

[0293] Frequency hopping based on carrier wave (CW), frequency hopping based on M-order miller coding, and active frequency hopping of a third device.

[0294] Among them, CW-based frequency hopping can be considered as a repetitive process with intervals for different passive IoT devices, and the interval can be implicitly indicated by a low level. Miller coding can be determined based on the chip length or the shortest high-level cycle. The active frequency hopping of the third device includes frequency shift keying (FSK) processing. This processing method requires the display of the frequency point indicating the frequency hopping. If it is continuous frequency hopping, there needs to be an interval between the frequency hopping.

[0295] like Figure 4 As shown, the transmitting end can perform coding and modulation processing on the first data sequence based on the indication information to obtain a coded data sequence. Furthermore, the coded data sequence can be subjected to bit-level frequency hopping processing. The coding and modulation processing includes convolution coding processing and binary phase shift keying modulation processing. The number of carrier frequencies is M, and the maximum value of M is an integer of 2. The symbols corresponding to 1, M+1, ..., (N1-1)*M+1 in the coded data sequence can be transmitted on the first carrier frequency, and the symbols corresponding to 2, M+2, ..., (N1-1)*M+2 can be transmitted on the second carrier frequency. 1 is the length of the coded data sequence. The receiving end can receive data on the first carrier frequency and the second carrier frequency, and combine the frequency hopping data to obtain the above coded data sequence, and then perform convolution decoding on the coded data sequence to obtain the first data sequence.

[0296] Or, if Figure 5As shown, the transmitting end can perform transmission block-level frequency hopping processing on the coded data sequence. The number of carrier frequencies is M, and the maximum value of M is an integer of 2. The first transmission block corresponding to the coded data sequence can be transmitted on the first carrier frequency, and the second transmission block can be transmitted on the second carrier frequency. The receiving end can receive data on the first carrier frequency, and directly perform demodulation and decoding after receiving, and the second node can receive data on the second carrier frequency, and directly perform demodulation and decoding after receiving.

[0297] In one example, Figure 6 As shown, the first transmission block is transmitted on the first carrier frequency f1, and the second transmission block and the terminator are transmitted on the second carrier frequency f2. There is a certain interval Gap between the transmissions of the two transmission blocks, and the interval can be implicitly indicated by a low level.

[0298] In another example, Figure 7 As shown, the first transmission block is transmitted on the first carrier frequency f1, the end character of the second transmission block does not perform frequency hopping, and the second transmission block is transmitted on the second carrier frequency f2. There is a certain interval Gap between the transmissions of the two transmission blocks, which can be implicitly indicated by a low level.

[0299] In some embodiments, Figure 8 As shown, the encoded data sequence can be subjected to repetition processing and frequency hopping processing.

[0300] The number of carrier frequencies is M, and the maximum value of M is an integer of 2. The data sequence after convolution coding, BPSK modulation and repetition processing can be called a repeated data sequence. The bits corresponding to 1, M+1, ..., (N2-1)*M+1 in the repeated data sequence are transmitted on the first carrier frequency, and the bits corresponding to 2, M+2, ..., (N2-1)*M+2 in the repeated data sequence are transmitted on the second carrier frequency, until the bits corresponding to M, 2*M, ..., (N2-1)*M+M in the repeated data sequence are transmitted on the Mth carrier frequency. Where N 2 is the length of the data sequence after convolution coding, BPSK modulation and repetition, that is, the length of the repeated data sequence, and N2 can divide M. The receiving end can receive data on the first carrier frequency and the second carrier frequency, and independently demodulate and decode the data received on the first carrier frequency and the second carrier frequency, or combine the data on the two carrier frequencies and then demodulate and decode to obtain a coded data sequence, and then perform convolution decoding on the coded data sequence to obtain a first data sequence.

[0301] Alternatively, the number of carrier frequencies is M, the maximum value of M is an integer of 2, the number of repetitions is P, and P is an integer greater than or equal to 1. The entire convolutional coded and BPSK modulated data sequence, that is, the coded data sequence, can be repeatedly processed, and then the coded, modulated and repeatedly processed data sequence, such as the bits corresponding to 1, M+1, ..., (N2-1)*M+1 in the repeated data sequence, can be transmitted on the first carrier frequency, and the bits corresponding to 2, M+2, ..., (N2-1)*M+2 in the coded data sequence can be transmitted on the second carrier frequency, until the bits corresponding to the coded data sequence M, 2*M, ..., (N2-1)*M+M are transmitted on the Mth carrier frequency. Where N 2 is the length of the data sequence after convolution coding, BPSK modulation and repetition, that is, the length of the coded data sequence, and N2 can divide M. The receiving end can receive data on the first carrier frequency and the second carrier frequency, and independently demodulate and decode the data received on the first carrier frequency and the second carrier frequency, or combine the data on the two carrier frequencies and then demodulate and decode to obtain the above-mentioned coded data sequence, and then perform convolution decoding on the coded data sequence to obtain the first data sequence.

[0302] Alternatively, the number of carrier frequencies is M, M is an integer with a maximum value of 2, the number of repetitions is P, P is an integer greater than or equal to 1, and regardless of bit-level repetition processing or transmission block-level repetition processing, the first transmission block obtained after repetition can be transmitted on the first carrier frequency, and the second transmission block obtained after repetition can be transmitted on the second carrier frequency.

[0303] In addition, similarly, the first transmission block is transmitted on the first carrier frequency f1, the second transmission block and the end symbol are transmitted on the second carrier frequency f2, and there is a certain interval between the transmission of the two transmission blocks, and the interval can be implicitly indicated by a low level. Alternatively, the first transmission block is transmitted on the first carrier frequency f1, the end symbol of the second transmission block does not perform frequency hopping, and the second transmission block is transmitted on the second carrier frequency f2. There is a certain interval between the transmission of the two transmission blocks, and the interval can be implicitly indicated by a low level.

[0304] In some embodiments, the code rate, repetition times and frequency hopping times of the convolutional coding may also be jointly coded and indicated. The indication information may be as shown in Table 5.

[0305] Table 5

[0306]

[0307]

[0308] Among them, based on the above independent indication, it can be known that the convolutional coding rate can take values ​​of 1 / 4, 1 / 3, 1 / 2, requiring 2 bits of indication information, the number of repetitions can take values ​​of 1, 2, 4, 8, 16, requiring 3 bits of indication information, the number of frequency hopping can take values ​​of 1, 2, requiring 1 bit of indication information, and a total of 6 bits of indication information are required. In the case of joint coding indication, only 5 bits of information are required, which saves 1 / 6 of the overhead compared to the 6 bits of information of independent indication. In this way, the overhead of indication information can be saved by means of joint coding indication.

[0309] In some embodiments, Fig. 9 As shown, the transmitting end may also perform Manchester encoding and binary on-off keying modulation on the first data sequence based on the indication information to obtain a coded data sequence.

[0310] The code rates used by Manchester coding may include 1 / 2, 1 / 4, and 1 / 8. When the code rate is 1 / 2, the output is 1 0, the input bit is 0, and the output is 0 1, or the input bit is 1, the output is 0 1, the input bit is 0, and the output is 1 0.

[0311] Furthermore, the transmitting end may also repeatedly process the encoded data sequence based on the indication information to obtain a second data sequence, and transmit the second data sequence.

[0312] The transmitting end may repeatedly process each bit in the coded data sequence, or repeatedly process the entire coded data sequence.

[0313] For example, when the value of the number of repetitions P is 2, the first data sequence is b 0 b 1 b 2 b 3 b 4 b 5 b 6 b 7 The Manchester coding rate is 1 / 2. After the first data sequence is processed by Manchester coding and binary on-off keying modulation, the coded data sequence is obtained.

If each bit in the coded data sequence is repeatedly processed, the second data sequence can be obtained

[0315] c0 , 1c0 , 1c0 , 2c0 , 2c1 , 1c1 , 1c1 , 2c1 , 2c2 , 1c2 , 1c2 , 2c2 , 2c3 , 1c3 , 1c3 , 2c3 , 2c4 , 1c4 , 1c4 , 2c4 , 2c5 , 1c5 , 1c5 , 2c5 , 2c6 , 1c6 , 1c6 ,2 c 6,2 c 7,1 c 7,1 c 7,2 c 7,2 , the second data sequence length N 2 =32. Thus, the second data sequence can be sent to the receiving end, and the receiving end can perform deduplication processing on the second data sequence based on the indication information to obtain a coded data sequence, and then perform demodulation and decoding processing on the coded data sequence to obtain the first data sequence.

[0316] For another example, when the number of repetitions P is 2, the first data sequence is b 0 b 1 b 2 b 3 b 4 b 5 b 6 b 7 The Manchester coding rate is 1 / 2. After the first data sequence is processed by Manchester coding and binary on-off keying modulation, the coded data sequence is obtained.

If the encoded data sequence is processed repeatedly as a whole, the second data sequence can be obtained

[0318] c0 , 1c0 , 2c1 , 1c1 , 2c2 , 1c2 , 2c3 , 1c3 , 2c4 , 1c4 , 2c5 , 1c5 , 2c6 , 1c6 , 2c7 , 1c7 , 2c0 , 1c0 , 2c1 , 1c1 , 2c2 , 1c2 , 2c3 , 1c3 , 2c4 , 1c4 , 2c5 ,1 c 5,2 c 6,1 c 6,2 c 7,1 c 7,2 , the second data sequence length N 2 =32. Thus, the second data sequence can be sent to the receiving end, and the receiving end can perform deduplication processing on the second data sequence based on the indication information to obtain a coded data sequence, and then perform demodulation and decoding processing on the coded data sequence to obtain the first data sequence.

[0319] In some embodiments, the coded data sequence may be subjected to repetition processing and frequency hopping processing. The number of carrier frequencies is M, the maximum value of M is equal to 2, the number of repetitions is P, and P is an integer greater than or equal to 1. After the first data sequence is subjected to Manchester encoding processing, binary on-off keying modulation processing, and repetition processing, the obtained data sequence is, for example, 1, M+1, ..., (N 2 -1)*M+1 corresponding bits are transmitted on the first carrier frequency. The repetition processing here can be bit-level repetition processing of the coded data sequence, or repetition processing of the entire coded data sequence. 2 -1)*M+2 corresponding bits are transmitted on the second carrier frequency until M, 2*M,..., (N 2 -1)*M+M corresponding bits are transmitted on the Mth carrier frequency. 2 is the length of the encoded data sequence, N 2 It can divide P. The receiving end can receive data on the first carrier frequency and the second carrier frequency, and demodulate and decode the data received on the first carrier frequency and the second carrier frequency independently, or combine the data on the two carrier frequencies and then demodulate and decode to obtain a first data sequence.

[0320] In some embodiments, the encoded data sequence can be subjected to repeated processing and frequency hopping processing, the number of carrier frequencies is M, the maximum value of M is equal to 2, the number of repetitions is P, P is an integer greater than or equal to 1, and the first transmission block obtained after Manchester encoding processing, binary on-off keying modulation processing and repeated processing is transmitted on the first carrier frequency, and the second transmission block is transmitted on the second carrier frequency.

[0321] In addition, similarly, the first transmission block is transmitted on the first carrier frequency f1, the second transmission block and the end symbol are transmitted on the second carrier frequency f2, and there is a certain interval between the transmission of the two transmission blocks, and the interval can be implicitly indicated by a low level. Alternatively, the first transmission block is transmitted on the first carrier frequency f1, the end symbol of the second transmission block does not perform frequency hopping, and the second transmission block is transmitted on the second carrier frequency f2. There is a certain interval between the transmission of the two transmission blocks, and the interval can be implicitly indicated by a low level.

[0322] In some embodiments, the coding information, repetition information, and carrier frequency information in the above indication information may be indicated independently or in combination. In some embodiments, the indication information may be indicated in a manner corresponding to a control field of a physical channel, a data field of a physical channel, a medium access control signaling, configured system information block information, or predefined configuration information.

[0323] Exemplarily, the coding information of Manchester coding and the number of repetitions in the indication information may be independently indicated.

[0324] For the code rate of Manchester coding, 1 bit of indication information may be used to indicate Manchester coding. Bit "0" indicates that Manchester coding is disabled, and bit "1" indicates that the code rate of Manchester coding is 1 / 2.

[0325] Alternatively, 1-bit indication information may be used to indicate Manchester coding. Bit "0" indicates that Manchester coding is disabled, and bit "1" indicates that the code rate of Manchester coding is 1 / 4.

[0326] Alternatively, 1-bit indication information may be used to indicate Manchester coding, where bit "0" indicates that Manchester coding is disabled, and bit "1" indicates that the code rate of Manchester coding is 1 / 4.

[0327] Alternatively, 2-bit indication information may be used to indicate Manchester coding. The data sequence "00" indicates that Manchester coding is disabled, the bit "01" indicates that the code rate of Manchester coding is 1 / 2, the data sequence "10" indicates that the code rate of Manchester coding is 1 / 4, and the bit "11" indicates that the code rate of Manchester coding is 1 / 8.

[0328] For the number of repetitions, 3 bits of indication information can be used to indicate the number of repetitions. The data sequence "000" indicates that the number of repetitions is 1, the data sequence "001" indicates that the number of repetitions is 2, the data sequence "010" indicates that the number of repetitions is 4, the data sequence "011" indicates that the number of repetitions is 8, and the data sequence "100" indicates that the number of repetitions is 16.

[0329] For the number of carriers, 1-bit indication information may be used to indicate the number of carriers. Bit "0" indicates that the number of carriers is 1, and bit "1" indicates that the number of carriers is 2.

[0330] In some embodiments, the code rate and the number of repetitions of the Manchester code in the indication information may be jointly coded and indicated. For example, the indication information may be as shown in Table 6.

[0345] The transmitting end may repeatedly process each bit in the coded data sequence, or repeatedly process the entire coded data sequence. The number of repetitions is P, where P is an integer greater than or equal to 1.

[0346] For example, when the value of the number of repetitions P is 2, the first data sequence is b 0 b 1 b 2 b 3 b 4 b 5 b 6 b 7 The code rate of convolution coding is 1 / 3, and the code rate of Manchester coding is 1 / 2. After the first data sequence is processed by convolution coding, Manchester coding and binary on-off keying modulation, the coded data sequence is obtained.

Thus, the second data sequence can be sent to the receiving end, and the receiving end can perform deduplication processing on the second data sequence based on the indication information to obtain a coded data sequence, and then perform demodulation and decoding processing on the coded data sequence to obtain the first data sequence.

Thus, the second data sequence can be sent to the receiving end, and the receiving end can perform deduplication processing on the second data sequence based on the indication information to obtain a coded data sequence, and then perform demodulation and decoding processing on the coded data sequence to obtain the first data sequence.

[0350] In some embodiments, the coded data sequence may be subjected to frequency hopping. The number of carrier frequencies is M, the maximum value of M is 2, the number of repetitions is P, and P is an integer greater than or equal to 1. After the first data sequence is coded and modulated, the coded data sequence obtained includes 1, M+1, ..., (N 1 -1)*M+1 corresponding bits are transmitted on the first carrier frequency, and 2,M+2,...,(N 1 -1)*M+2 corresponding bits are transmitted on the second carrier frequency until M, 2*M,..., (N 2 -1)*M+M corresponding bits are transmitted on the Mth carrier frequency. 1 The receiving end can receive data on the first carrier frequency and the second carrier frequency, and demodulate and decode the data received on the first carrier frequency and the second carrier frequency independently, or combine the data on the two carrier frequencies and then demodulate and decode to obtain the first data sequence.

[0351] In some embodiments, the coded data sequence may be subjected to repetition processing and frequency hopping processing. The number of carrier frequencies is M, the maximum value of M is equal to 2, the number of repetitions is P, and P is an integer greater than or equal to 1. After the first data sequence is subjected to encoding processing, binary on-off keying modulation processing, and repetition processing, the obtained data sequence is, for example, 1, M+1, ..., (N 2 -1)*M+1 corresponding bits are transmitted on the first carrier frequency. The repetition processing here can be bit-level repetition processing of the coded data sequence. 2 -1)*M+2 corresponding bits are transmitted on the second carrier frequency until M, 2*M,..., (N2 -1)*M+M corresponding bits are transmitted on the Mth carrier frequency. 2 is the length of the encoded data sequence, N 2 It can divide P. The receiving end can receive data on the first carrier frequency and the second carrier frequency, and demodulate and decode the data received on the first carrier frequency and the second carrier frequency independently, or combine the data on the two carrier frequencies and then demodulate and decode to obtain a first data sequence.

[0352] In some embodiments, the coded data sequence can be subjected to repetition processing and frequency hopping processing. The number of carrier frequencies is M, the maximum value of M is equal to 2, the number of repetitions is P, and P is an integer greater than or equal to 1. After the first data sequence is subjected to encoding processing, binary on-off keying modulation processing, and repetition processing, the coded data sequence obtained includes 1, M+1, ..., (N 2 -1)*M+1 corresponding bits are transmitted on the first carrier frequency. The repetition processing here can repeat the entire coded data sequence. 2 -1)*M+2 corresponding bits are transmitted on the second carrier frequency until M, 2*M,..., (N 2 -1)*M+M corresponding bits are transmitted on the Mth carrier frequency. 2 is the length of the encoded data sequence, N 2 It can divide P. The receiving end can receive data on the first carrier frequency and the second carrier frequency, and demodulate and decode the data received on the first carrier frequency and the second carrier frequency independently, or combine the data on the two carrier frequencies and then demodulate and decode to obtain a first data sequence.

[0353] In some embodiments, the coded data sequence can be subjected to repeated processing and frequency hopping processing, the number of carrier frequencies is M, the maximum value of M is equal to 2, the number of repetitions is P, P is an integer greater than or equal to 1, and the first transmission block obtained after the coding processing, binary on-off keying modulation processing and repeated processing is transmitted on the first carrier frequency, and the second transmission block is transmitted on the second carrier frequency.

[0354] In addition, similarly, the first transmission block is transmitted on the first carrier frequency f1, the second transmission block and the end symbol are transmitted on the second carrier frequency f2, and there is a certain interval between the transmission of the two transmission blocks, and the interval can be implicitly indicated by a low level. Alternatively, the first transmission block is transmitted on the first carrier frequency f1, the end symbol of the second transmission block does not perform frequency hopping, and the second transmission block is transmitted on the second carrier frequency f2. There is a certain interval between the transmission of the two transmission blocks, and the interval can be implicitly indicated by a low level.

[0355] In some embodiments, the frequency hopping mode may include one of the following:

[0356] Frequency hopping based on carrier signal, frequency hopping based on M-order miller coding, and active frequency hopping of a third device.

[0357] Among them, CW-based frequency hopping can be considered as a repetitive process with intervals for different passive IoT devices, and the interval can be implicitly indicated by a low level. Miller coding can be determined based on the chip length or the shortest high-level cycle. The active frequency hopping of the third device includes frequency shift keying processing. This processing method requires the display of the frequency point indicating the frequency hopping. If it is continuous frequency hopping, there needs to be an interval between the frequency hopping.

The data sequence "000" indicates that the number of repetitions is 1, the data sequence "001" indicates that the number of repetitions is 2, the data sequence "010" indicates that the number of repetitions is 4, the data sequence "011" indicates that the number of repetitions is 8, and the data sequence "100" indicates that the number of repetitions is 16.

[0365] For the number of carriers, 1-bit indication information may be used to indicate the number of carriers. Bit "0" indicates that the number of carriers is 1, and bit "0" indicates that the number of carriers is 2.

[0366] In some embodiments, the code rate, number of repetitions and number of carriers of the convolutional coding and Manchester coding in the indication information may be jointly coded and indicated. For example, the indication information may be as shown in Table 9.
