[0037] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present disclosure.

[0038] Unless otherwise required by context, as used herein the term "comprise" and variations of the term, such as "comprises" and "comprising," will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps. In describing the disclosure, the terms "one embodiment," "some embodiments,” “exemplary embodiments,” “example,” “specific example” or “some examples” are used to indicate that a particular feature, structure, material, or characteristic is included in at least one embodiment or example of the disclosure. Such terms are not necessarily used consistently herein. The terms “first,” “second,” and the like are used to describe various elements, and do not necessarily indicate relative importance or a particular order. Thus, a feature described as a “first” feature can also be a “second” feature, and vice versa. The terms “a” and “an” are used to mean one or more, unless otherwise indicated.

[0039] The terms “first,” “second,” and the like are used to describe various elements, and do not necessarily indicate relative importance or a particular order. Thus, a feature described as a “first” feature can also be a “second” feature, and vice versa. The terms “a” and “an” are used to mean one or more, unless otherwise indicated.

[0040] In the description of the disclosure, the words “exemplary” and “for example” are used to illustrate examples and do not mean “preferred” or “advantageous”. In fact, the words “exemplary” and “for example” are used to present concepts in a manner that enables a person skilled in the art to use the concepts.

[0041] In addition, the use of “based on” means open and inclusive, as the process, step, calculation or other action based on one or more stated conditions or values can be based on additional conditions or values beyond those stated.

[0042] In the description of the disclosure, unless otherwise stated, “ / ” means “or”, for example, A / B can mean A or B. “And / or” in this document is only a description of the relationship between the associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: only A, only B, and A and B.

[0043] It is to be understood that the functions, steps, etc. shown in the present disclosure can occur in an order other than that shown in the present disclosure, without conflicting.

[0044] At present, as a highly integrated and comprehensive application of new generation information technology, the application of Internet of Things is becoming more and more extensive. With the continuous popularization of wearable devices, smart home, intelligent networked vehicles, smart cities and other technologies, hundreds of billions of devices will be connected to the network, and Internet of Things applications will also develop towards ubiquitous and popularization. Due to its technical characteristics of supporting massive device access, low cost, and passive, passive Internet of Things has gradually become the focus of attention in related fields.

[0045] However, due to the limited energy supply, low-power design, and susceptibility to environmental influences of passive Internet of Things devices, their data transmission performance is greatly affected. Therefore, how to improve the data transmission performance based on passive Internet of Things is a technical problem to be solved in related fields.

[0046] Passive Internet of Things devices in passive Internet of Things can not be configured with a battery, nor can they obtain power from the power grid in a wired manner, but they can obtain the required energy from the environment to support the sensing, computing, and wireless transmission of passive Internet of Things devices. However, since passive Internet of Things devices need to collect energy from the environment to maintain operation, the energy supply is relatively limited, so there may not be enough energy to provide high sensitivity during data transmission, and the reliability of data transmission is low. Moreover, since passive Internet of Things devices need to collect energy from the environment, their performance is easily affected by environmental factors, such as changes in light intensity, temperature, and other environmental factors, which can affect the energy collection and data transmission performance of the device. In addition, passive Internet of Things devices usually adopt low-power design to achieve energy saving and prolong service life, which may limit the receiving power and receiving sensitivity of passive Internet of Things devices when receiving data.

[0047] In addition, in a communication system, the sending end can perform channel coding on the first data sequence to obtain a coded data sequence, then map the coded data sequence to constellation modulation symbols, and finally transmit the obtained constellation modulation symbols based on the channel. During the data transmission based on the channel, factors such as multipath, movement, noise, and interference can all cause data transmission distortion, and forward error correction (FEC) coding channel coding can be used to improve the reliability and efficiency of data transmission. 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 recover the original information data sequence according to the corresponding forward error correction coding principle.

[0048] For example, the convolutional coding can be used to introduce redundant bits in the input information bits, so that the coded data sequence has a certain error correction capability. For example, the previous N input symbols and the current output symbol can be weighted and summed according to a certain proportion, so as to obtain the current output symbol. Therefore, each output symbol is related to not only the current input symbol, but also some previous input symbols. In order to reduce the performance loss caused by burst interference, the traditional convolutional coding scheme usually adds sub-block interleaving, bit collection and bit selection modules. For example, in the fourth generation mobile communication, the control channel adopts convolutional coding with constraint length 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 sequentially stored in the circular buffer, and finally the output data sequence of the corresponding length is obtained through the bit selection method. Through the interleaving operation, the code bits of the convolutional code belonging to the same grid can be dispersed as much as possible, so as to improve the anti-interference ability of the channel to sudden fading and interference.

[0049] However, for passive Internet of Things devices, it is crucial to keep the device simple and minimize energy consumption. The sub-block interleaving, bit collection and bit selection operations in the traditional convolutional coding scheme will increase the complexity of the hardware and may cause additional energy consumption, which is very disadvantageous for resource-constrained passive Internet of Things devices such as tag devices. Therefore, passive Internet of Things devices cannot use traditional convolutional coding to improve the anti-interference ability of the channel to sudden fading and interference, so that the data transmission performance is low.

[0050] In summary, how to improve the data transmission performance based on passive Internet of Things is a technical problem to be solved in the related field.

[0051] Therefore, the present disclosure provides a data transmission method, which can perform encoding processing, repetition processing, frequency hopping processing, etc. on the data sequence to be transmitted, and then transmit the processed data sequence. The encoding processing can improve the transmission reliability of the data, the repetition processing can use continuous retransmission when the transmission environment is unstable or the communication distance is far, thereby improving the transmission reliability of the data, reducing the bit error rate and improving the sensitivity of receiving the data. The frequency hopping processing can disperse the carrier frequency of the transmission signal according to a predetermined rule through spread spectrum, thereby improving the anti-interference and confidentiality of the communication. Therefore, based on the technical scheme, the data transmission performance based on passive Internet of Things can be improved.

[0052] The data transmission method provided by the present disclosure can be applied to various communication systems, for example, can be an internet of things (IoT), narrow band internet of things (NB-IoT), long term evolution (LTE), can also be a 5th generation (5G) communication system, can also be a hybrid architecture of LTE and 5G, can also be a 6G or a new communication system appearing in future communication development, etc. The communication system can also be a machine to machine (M2M) network, machine type communication (MTC), or other network. The communication system can also be a passive internet of things network communication system.

[0053] 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 / writer and a tag.

[0054] FIG. 1 is a schematic diagram of an architecture of a passive internet of things system provided by the present disclosure. As shown in FIG. 1, the passive internet of things system 100 can include a helper 101, a reader / writer 102, and a tag 103.

[0055] The helper 101 is an available environmental radio frequency source, for example, a broadcast television signal transmission tower, a mobile communication system base station, a wireless fidelity (Wi-Fi) access point, etc., and the specific form of the present disclosure is not limited. In some embodiments, the helper 101 can send a wireless radio frequency signal in a communication frequency range.

[0056] The reader / writer 102, which can also be referred to as a reader, can also be a node (Node) or an intermediate user equipment (Intermediate UE) in the network. The reader / writer 102 can be used to send radio frequency energy to activate the tag 103, and to receive and analyze the data transmitted by the tag 103.

[0057] 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 by backscattering technology to transceive messages. Exemplarily, the tag 103 can be a radio frequency identification (RFID), Bluetooth, Zigbee, etc. When energy is needed, the tag 103 can receive a carrier wave for energy harvesting (CW for EH) sent by the reader 102 to harvest energy needed for receiving and transmitting signals.

[0058] In some embodiments, during the data transmission process of the tag 103 to the reader 102, the tag 103 can also be referred to as a sending end, and the reader 102 can be referred to as a receiving end.

[0059] In some embodiments, the tag 103 can also be referred to as a terminal, such as an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, a mobile device, a user terminal, a wireless communication device, etc. The terminal can also be a passive Internet of Things terminal or a passive Internet of Things device.

[0060] In some embodiments, based on the energy storage capability and signal transmission capability, data rate, coverage range, and other characteristics of the device, the passive Internet of Things device includes at least the following device types:

[0061] Device Type I: which can also be referred to as Device 1, and the device of this type can also be referred to as a first device in the present disclosure. The first device corresponds to a passive device, has no energy storage device, and has a peak power consumption of about 1 microwatt. Moreover, the first device has no downlink and uplink amplification function, 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 device with low coverage.

[0062] Device Type II: which can also be referred to as Device 2a, and the device of this type can also be referred to as a second device in the present disclosure. The second device is a semi-passive device, has a small amount of energy storage device, and has a peak power consumption of about several hundred microwatts. Moreover, the second device can include downlink and / or uplink amplification function. Although the device can have amplification function internally, the uplink signal is still transmitted by backscattering, but the second device can transmit the signal from the device (Device) to the reader (Reader) (Device-to-Reader, D2R) by backscattering. The device corresponding to the second device can also be a medium-rate device or a device with medium coverage.

[0063] Device type III: can also be denoted as Device 2b, which can also be referred to as a third device in the present disclosure. The third device corresponds to an active device, has an energy storage device, and has a peak power consumption of about several hundred microwatts. In addition, the third device can include downlink and / or uplink amplification functions. The uplink transmission of the third device is generated autonomously by the device, that is, the device can backscatter without relying on an external carrier to generate and send a D2R signal autonomously. The third device can also be a high-rate device or a large-coverage device.

[0064] It should be noted that the high rate, medium rate and low rate mentioned above are relative values of the respective supported rates of the three types of devices. In addition, the low coverage, medium coverage and large coverage mentioned above are relative values of the respective supported coverage ranges of the three types of devices.

[0065] It should be noted that the system architecture shown in FIG. 1 is only used to more clearly illustrate the technical solutions of the present disclosure, and does not constitute a limitation on the present disclosure. Those skilled in the art can know that as the network architecture evolves and new business scenarios appear, the technical solutions provided by the present disclosure are also applicable to similar technical problems.

[0066] The embodiments provided by the present disclosure will be described below with reference to the accompanying drawings.

[0067] As shown in FIG. 2, the present disclosure provides a data transmission method, executed by a sending end, and the method comprises:

[0068] S101, obtaining a first data sequence to be transmitted.

[0069] The first data sequence can be a data sequence obtained by performing preliminary processing on an initial information data sequence to be transmitted. For example, the sending end can perform cyclic redundancy check (CRC) encoding processing on the initial information data sequence to be transmitted, thereby obtaining the first data sequence.

[0070] In some embodiments, the sending end can determine the first data sequence according to transmission data information.

[0071] The transmission data information can include a size range of a transmission block, and the length of the first data sequence is determined based on the size of the transmission block. The size range of the transmission block can include at least one of a maximum transmission block size, a minimum transmission block size, and a set of available transmission block sizes.

[0072] In some embodiments, the transmission data information can be determined based on the first information, for example, the transmission data information can be determined based on a size range of the transport block supported by the sending end indicated by the first information. The first information at least comprises a device type of the sending end, so that the sending end indicated by the first information comprises the first device, the second device or the third device, and the first device, the second device and the third device are three devices of different device types. For example, taking the sending end as a passive Internet of Things device, the first information can be used to indicate Device 1, Device 2a or Device 2b.

[0073] In some embodiments, the maximum transport block size determined according to the first information satisfies any one of the following:

[0075] The maximum transport block size supported by the third device is greater than the maximum transport block size supported by the second device, and the maximum transport block size supported by the second device is greater than the maximum transport block size supported by the first device.

[0076] For example, the first device and / or the second device support a first maximum transport block size, the third device supports a second maximum transport block size, and the second maximum transport block size is greater than the first transport block size. Alternatively, the first device supports a third maximum transport block size, the second device and / or the third device support a fourth maximum transport block size, and the fourth maximum transport block size is greater than the third maximum transport block size.

[0079] The minimum transport block size supported by the third device is greater than the minimum transport block size supported by the second device, and the minimum transport block size supported by the second device is greater than the minimum transport block size supported by the first device.

[0080] For example, the first device and / or the second device supports a first minimum transport block size, the third device supports a second minimum transport block size, and the second minimum transport block size is greater than the first transport block size. Alternatively, the first device supports a third minimum transport block size, the second device and / or the third device supports a fourth minimum transport block size, and the fourth minimum transport block size is greater than the third minimum transport block size. Alternatively, the first device supports a fifth minimum transport block size, the second device supports a sixth minimum transport block size, and the third device supports a seventh minimum transport block size, and the seventh minimum transport block size is greater than the sixth minimum transport block size.

[0081] In some embodiments, the set of transport block sizes determined according to the first information satisfies any one of the following:

[0082] The set of transport block sizes supported by the first device is a subset of the set of transport block sizes supported by the third device, and the set of transport block sizes supported by the second device is the same as the set of transport block sizes supported by the first device or the third device;

[0083] The set of transport block sizes supported by the first device is a subset of the set of transport block sizes supported by the second device, and the set of transport block sizes supported by the second device is a subset of the set of transport block sizes supported by the third device.

[0084] For example, the first device and / or the second device supports a first set of transport block sizes, and the third device supports a second set of transport block sizes, and the first set of transport block sizes is a subset of the second set of transport block sizes. Alternatively, the first device supports a third set of transport block sizes, and the second device and / or the third device supports a fourth set of transport block sizes, and the third set of transport block sizes is a subset of the fourth set of transport block sizes. Alternatively, the first device supports a fifth set of transport block sizes, the second device supports a sixth set of transport block sizes, and the third device supports a seventh set of transport block sizes, and the fifth set of transport block sizes is a subset of the sixth set of transport block sizes, and the sixth set of transport block sizes is a subset of the seventh set of transport block sizes.

[0085] S102, processing the first data sequence to obtain a second data sequence, and sending the second data sequence; wherein the processing includes at least one of encoding processing, repetition processing, and frequency hopping processing.

[0086] In some embodiments, the encoding processing is performed based on encoding information, and the encoding information is determined according to the first information and / or the second information.

[0087] The second information at least includes a spectrum deployment mode and a number of available carriers type, the spectrum deployment mode (also referred to as an operation mode) includes an inband mode, a guardband mode or a standalone mode, and the number of available carriers type includes a single tone type or a multiple tone type. The encoding information includes at least one of an encoding mode and a value range of an encoding code rate. In some embodiments, the second information can further include a signal attribute, which includes at least one of a preamble, a midamble and a postamble.

[0088] In some embodiments, the encoding mode includes an encoding mode supported by the sending end indicated by the first information. The encoding mode determined according to the first information satisfies at least one of the following conditions:

[0089] The encoding mode supported by the first device includes a line code encoding mode;

[0090] The encoding mode supported by the second device includes a line code encoding mode and / or a convolutional encoding mode;

[0091] The encoding mode supported by the third device includes a line code encoding mode and / or a convolutional encoding mode.

[0092] Exemplarily, the encoding mode determined according to the first information at least has the following examples:

[0093] The encoding mode of the first device is a line code encoding mode, the encoding mode supported by the second device is a line code encoding mode, and the encoding mode supported by the third device is a convolutional encoding mode. Alternatively, the encoding mode of the first device is a line code encoding mode, the encoding mode supported by the second device is a convolutional encoding mode, and the encoding mode supported by the third device is a convolutional encoding mode. Alternatively, the encoding mode of the first device is a line code encoding mode, the encoding mode supported by the second device is a line code encoding mode, and the encoding mode supported by the third device is a convolutional encoding mode and a line code encoding mode. Alternatively, the encoding mode of the first device is a line code encoding mode, the encoding mode supported by the second device is a convolutional encoding mode, and the encoding mode supported by the third device is a convolutional encoding mode and a line code encoding mode.

[0094] In some embodiments, the length of the convolutional encoding mode is 3 to 9. In an example, the length of the convolutional encoding mode is 3 or 7.

[0095] In some embodiments, when the encoding mode is a line code encoding mode, the encoding code rate is at least one of 1 / 8, 1 / 4 and 1 / 2. When the encoding mode in the encoding information is a convolutional encoding mode, the encoding code rate is at least one of 1 / 4, 1 / 3, 1 / 2 and 2 / 3.

[0096] In some embodiments, the line code encoding mode includes at least one of Manchester encoding, Miller encoding, Bi-Phase Space Coding (FM0) encoding, first line code encoding and second line code encoding.

[0097] Exemplarily, each line code encoding mode is introduced as follows:

[0098] Manchester encoding

[0099] Manchester encoding can also be called self-synchronous code or phase encoding, and can maintain synchronization between a sending device and a receiving device through a transition of signal level. The rule of Manchester encoding is as follows:

[0100] At the middle moment of each bit period, the signal has a transition.

[0101] Bit 0 starts with a transition from high level to low level, and then maintains low level to the end of the bit period (the output sequence is [1 0]).

[0102] Bit 1 starts with a transition from low level to high level, and then maintains high level to the end of the bit period (the output sequence is [0 1]).

[0103] Exemplarily, the code rate of Manchester encoding is 1 / 2, and 2 bits can be encoded and output for each input bit. For example, the input data sequence is [1 0 1 1], and 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].

[0104] In some embodiments, the code rate of Manchester encoding can also be 1 / 4, and 4 bits can be encoded and output for each input bit. For example, the output sequence [1 0 1 0] represents bit 1, and the output sequence [0 1 0 1] represents bit 0. Alternatively, the output sequence [1 0 1 0] represents bit 0, and the output sequence [0 1 0 1] represents bit 1.

[0105] Alternatively, the code rate of the Manchester coding can also be 1 / 6, and 1 bit of input can be encoded to output 6 bits. For example, the output sequence [1 0 1 0 1 0] represents bit 1, and the output sequence [0 1 0 1 0 1] represents bit 0. Alternatively, the output sequence [1 0 1 0 1 0] represents bit 0, and the output sequence [0 1 0 1 0 1] represents bit 1.

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

[0107] In some embodiments, the code rate of the Manchester coding can also be 1 / z, and 1 bit of input can be encoded to output z bits. Z can be an even number greater than 0, for example, Z can be 8, 10, 12, 14, 16, 18, 20, 22, 24, etc. And the output sequence corresponding to the input bit 1 is the sequence obtained by repeating [1 0] z / 2 times, and the output sequence corresponding to the input bit 0 is the sequence obtained by repeating [0 1] z / 2 times. Alternatively, the output sequence corresponding to the input bit 0 is the sequence obtained by repeating [1 0] z / 2 times, and the output sequence corresponding to the input bit 1 is the sequence obtained by repeating [0 1] z / 2 times.

[0108] Miller coding

[0109] Miller coding is a line coding technique for serial communication, which represents the logic value of the corresponding bit by the level change in the bit window. If the logic information to be sent is "1", the level inversion occurs at the middle position of the bit window. If the logic information to be sent is "0", the level inversion does not occur at the middle position of the bit window. The bit window with logic information "1" does not have level inversion at the starting position. The bit window with logic information "0" usually also does not have level inversion at the starting position, but in the case where the logic information of the two consecutive bit windows is "0", the starting position of the second "0" bit window will have level inversion to provide synchronization information. For example, assuming that the input data sequence is X = [1 0 0 0 1 1 1 0], the line coding sequence Y obtained by Miller coding the input data sequence is Y = [1 0 0 0 1 1 0 0 0 1 1 0 1 1 1].

[0110] In addition, the Miller coding can be M-order subcarrier Miller coding. In the M-order subcarrier Miller coding, each bit window contains M subcarrier periods in the duration of the bit window. Exemplarily, the value of M can include at least one of the following: 1, 2, 4, 8, 16, 32, 48, 64, 96, and 128.

[0111] In the M-order subcarrier Miller coding, the parameter M can indeed be used to mark the change of the subcarrier frequency or the data rate of the Miller coding. Since the duration of each bit window remains unchanged, but the bit window is subdivided into more subcarrier periods, the data rate is correspondingly reduced. For example, the data rate is reduced to 1 / M of the original data rate. For example, if M is equal to 2, that is, two subcarrier periods are contained in each bit window, then the data rate is reduced to 1 / 2 of the original data rate. When M is greater than 1, the M-order subcarrier Miller coding is actually the result of multiplying the encoded data sequence output by the 1-order Miller coding with the subcarrier signal. Exemplarily, the input data sequence is X = [1 0 0 0 1 1 0], and the 2-order subcarrier Miller coding is adopted for the first data sequence, and the resulting line coding sequence is Y = [1 0 0 1 0 1 0 1 1 0 1 0 0 1 0 1 0 1 1 0 1 0 0 1 0 1 1 0 1 0 1 0].

[0112] Dual-phase space coding

[0113] In the dual-phase space 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 always flips. After the starting position of the bit window flips, the level in the bit window remains unchanged, that is, there is no intermediate flip, and the logic information corresponding to the bit window is “1”. After the starting position of the bit window flips, the flip occurs again at the middle position of the bit window, and the logic information corresponding to the bit window is “0”.

[0114] Exemplarily, assuming that the input data sequence is X = [1 0 0 0 1 1 0 0], the line coding sequence after the dual-phase space coding processing of the input data sequence is Y = [0 0 1 0 1 0 1 0 1 1 0 0 1 0 1 0]. The bit ‘1’ can be considered as a high-level bit, and the bit ‘0’ can be considered as a low-level bit.

[0115] First line coding

[0116] The first line code coding is used to indicate that 1 bit is converted into multiple bits, or, a bit with a value of 0 in the multiple bits is converted into a low level and a bit with a value of 1 in the multiple bits is converted into a high level, or, a bit with a value of 0 in the multiple bits is converted into a high level and a bit with a value of 1 in the multiple bits is converted into a low level.

[0117] The second line code coding is used to indicate that 1 bit is converted into multiple bits, or, a bit with a value of 0 in the multiple bits is converted into a negative level and a bit with a value of 1 in the multiple bits is converted into a positive level, or, a bit with a value of 0 in the multiple bits is converted into a positive level and a bit with a value of 1 in the multiple bits is converted into a negative level.

[0118] The second line code coding is used to indicate that 1 bit is converted into multiple bits, or, a bit with a value of 0 in the multiple bits is converted into a negative level and a bit with a value of 1 in the multiple bits is converted into a positive level, or, a bit with a value of 0 in the multiple bits is converted into a positive level and a bit with a value of 1 in the multiple bits is converted into a negative level.

[0250] Based on the technical solutions provided in the present disclosure, the data sequence to be transmitted can be encoded, repeated, frequency-hopped, and the like, and then processed and transmitted. The encoding processing can improve the transmission reliability and transmission distance of the data, the repeated processing can use continuous retransmission when the transmission environment is unstable or the communication distance is far, thereby improving the transmission reliability of the data, reducing the error rate, and improving the sensitivity of receiving the data. The frequency hopping processing can make the carrier frequency of the transmission signal change discretely according to a predetermined rule through spread spectrum, thereby improving the anti-interference and confidentiality of the communication. Thus, based on the technical solutions, the data transmission performance based on the passive Internet of Things can be improved.

[0251] In some embodiments, the sending end can also receive indication information. The indication information includes at least one of the above-mentioned transmission data information, encoding information, repeated information, and frequency hopping information. That is, the indication information can be determined based on the first information and / or the second information. For example, the sending end can receive indication information, which can include transmission data information. For example, the sending end is a passive Internet of Things device, which can receive the indication information sent by the reader, and then perform at least one of the encoding processing, repeated processing, and frequency hopping processing on the first data sequence based on the indication information.

[0252] In an example, the indication information includes an encoding manner, an encoding code rate, a repeated number, and a carrier number and a frequency hopping number. For example, the encoding manner includes convolutional encoding and binary phase shift keying modulation.

[0253] At this time, as shown in FIG. 3, the sending end can perform encoding and modulation processing, such as convolutional encoding processing and binary phase shift keying modulation processing, on the first data sequence based on the indication information, to obtain an encoded data sequence.

[0254] The code rate adopted by the convolutional encoding includes 1 / 2, 1 / 3, 1 / 4, and 2 / 3. When the code rate is 1 / 2, the input bit is b0, and the output is c0 and c1. When the code rate is 1 / 3, the input bit is b0, and the output is c0, c1, and c2. When the code rate is 2 / 3, the input bit is b0 and b1, and the output is c0, c1, c2, and c3. In addition, the constraint length of the convolutional encoding can be 3 to 9, such as 3, 6, 7, and 8. The binary phase shift keying modulation mode can be π / 2 offset binary phase shift keying modulation or π / 4 offset binary phase shift keying modulation.

[0255] Further, the sending end can also perform repetition processing on the encoded data sequence based on the indication information. As shown in FIG. 3, the second data sequence can be obtained after the repetition processing.

[0256] The sending end can perform repetition processing on each bit in the encoded data sequence, or perform repetition processing on the entire encoded data sequence. The repetition number can be P, and P is an integer greater than or equal to 1. Further, the second data sequence can be obtained, and the second data sequence can be transmitted on different carriers according to the carrier information.

[0257] For example, when the repetition number P is 2, the first data sequence is b0b1b2b3b4b5b6b7, and the encoding code rate of the convolutional encoding is 1 / 2. After the first data sequence is processed by the convolutional encoding and the binary phase shift keying modulation, the encoded data sequence 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 bit b i After the encoding and modulation, c i,1 c i,2 , i = 0, 1,..., 7, and the length of the encoded data sequence N1 = 16. If each bit in the encoded data sequence is repeated, the second data sequence c 0,1 c 0,1 c 0,2 c 0,2 c1,1 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 N2=32. Thus the second data sequence can be sent to the receiving end, the receiving end can be based on the indication information on the second data sequence de-repetition processing, to obtain the above-mentioned encoding data sequence, and then the encoding data sequence is convolutional decoding processing, to obtain the first data sequence.

[0258] For example, the number of repetitions P is 2, the first data sequence is b0b1b2b3b4b5b6b7, the convolutional encoding code rate is 1 / 2, after the first data sequence is processed by convolutional encoding and binary phase shift keying modulation, the encoding data sequence 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 . Bit b i After encoding modulation, c i,1 c i,2 , i=0, 1,..., 8, and the encoding data sequence length N1=16. If the entire encoding data sequence is repeated, the second data sequence 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 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 N2=32. Thus the second data sequence can be sent to the receiving end, and the receiving end can perform de-repetition processing on the second data sequence based on the indication information to obtain the above-mentioned encoded data sequence, and then perform convolution decoding processing on the encoded data sequence to obtain the first data sequence.

[0259] In some embodiments, the encoding information, repetition information, and frequency hopping information in the above-mentioned indication information can be independently indicated or jointly encoded and indicated.

[0260] In some embodiments, the indication information can be indicated by a control field of a physical channel (physical random access channel, PRACH), a data field of the physical channel, medium access control (MAC) signaling, or a configured system information block (SIB) or a predefined configuration information corresponding manner.

[0261] For example, the encoding information of convolution encoding and the repetition number, carrier number, and frequency hopping number in the indication information can be independently indicated.

[0262] For convolution encoding, 1-bit indication information can be used to indicate convolution encoding. Bit "0" indicates that convolution encoding is not enabled, and bit "1" indicates that the code rate of convolution encoding is 1 / 2.

[0263] Alternatively, 1-bit indication information can be used to indicate convolution encoding. Bit "0" indicates that convolution encoding is not enabled, and bit "1" indicates that the code rate of convolution encoding is 1 / 3.

[0264] Alternatively, 1-bit indication information can be used to indicate the convolutional coding. Bit "0" indicates that the convolutional coding is disabled, and bit "1" indicates that the code rate of the convolutional coding is 1 / 4.

[0265] Alternatively, 2-bit indication information can be used to indicate the convolutional coding. Data sequence "00" indicates that the convolutional coding is disabled, bit "01" indicates that the code rate of the convolutional coding is 1 / 2, data sequence "10" indicates that the code rate of the convolutional coding is 1 / 3, and bit "11" indicates that the code rate of the convolutional coding is 1 / 4.

[0266] For the repetition number, 3-bit indication information can be used to indicate the repetition number. Data sequence "000" indicates that the repetition number is 1, data sequence "001" indicates that the repetition number is 2, data sequence "010" indicates that the repetition number is 4, data sequence "011" indicates that the repetition number is 8, and data sequence "100" indicates that the repetition number is 16.

[0267] For the number of carriers, 1-bit indication information can 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.

[0268] For the frequency hopping number, 1-bit indication information can be used to indicate the frequency hopping number. Bit "0" indicates that there is no frequency hopping, and bit "1" indicates that there is frequency hopping, and the frequency hopping number is 2.

[0269] In some embodiments, the code rate of the convolutional coding and the repetition number, the number of carriers, and the frequency hopping number in the indication information can be jointly encoded and indicated. Exemplarily, in the case of single carrier by default, the indication information can be as shown in Table 1.

[0270] Table 1

[0271] Alternatively, the indication information can be as shown in Table 2.

[0272] Table 2

[0273] Based on the above independent indication, it can be known that the convolutional coding code rate can take values of 1 / 4, 1 / 3, and 1 / 2, 2 bits of indication information are required, the repetition number can take values of 1, 2, 4, 8, and 16, 3 bits of indication information are required, and a total of 5 bits of indication information are required. In the case of joint encoding indication, only 4 bits of information are required, which saves 1 / 5 of the overhead compared with the 5 bits of information in the independent indication. In this way, by means of joint encoding indication, the amount of indication information overhead can be saved.

[0274] Alternatively, the code rate of the convolutional coding and the repetition number, and the number of carriers can also be jointly encoded and indicated. The indication information can be as shown in Table 3.

[0275] Table 3

[0276] Alternatively, the indication information can also be as shown in Table 4.

[0277] Table 4

[0278] Based on the above independent indication, the convolutional code rate can take values 1 / 4, 1 / 3, 1 / 2, 2 bits of indication information are required, the repetition number can take values 1, 2, 4, 8, 16, 3 bits of indication information are required, the carrier number can take values 1, 2, 1 bit of indication information is required, a total of 6 bits of indication information is required. In the case of joint encoding indication, only 5 bits of information are required, compared with 6 bits of information in the case of independent indication, 1 / 6 of the overhead is saved. In this way, by means of joint encoding indication, the amount of indication information overhead can be saved.

[0279] In some embodiments, the frequency hopping manner can include one of the following:

[0280] Frequency hopping based on carrier wave (CW), frequency hopping based on m-order miller encoding, active frequency hopping of the third device.

[0281] Frequency hopping based on CW, for different passive Internet of Things devices, can be considered as a kind of interval repetition processing, which can be indicated by low-level implicit indication. Miller encoding can be determined according to chip length or shortest high-level period. Active frequency hopping of the third device includes frequency-shift keying (FSK) processing, which requires explicit indication of frequency points for frequency hopping. If it is continuous frequency hopping, there needs to be an interval between frequency hopping.

[0282] As shown in FIG. 4, the sending end can perform encoding and modulation processing on the first data sequence based on the indication information to obtain an encoded data sequence. Further, bit-level frequency hopping processing can be performed on the encoded data sequence. The encoding and modulation processing includes convolutional encoding processing and binary phase shift keying modulation processing. The number of carrier frequencies is M, and the maximum value of M is an integer. The symbols corresponding to 1, M+1,..., (N1-1)*M+1 in the encoded 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. N1 is the length of the encoded data sequence. The receiving end can receive data on the first carrier frequency and the second carrier frequency, combine the frequency-hopped data, obtain the above-mentioned encoded data sequence, then perform convolutional decoding on the encoded data sequence to obtain the first data sequence.

[0283] Or, as shown in FIG. 5, the sending end can perform the transmission block level frequency hopping processing on the coded data sequence. The number of carrier frequencies is M, and M is an integer with the maximum value 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 the reception. The receiving end can receive data on the second carrier frequency, and directly perform demodulation and decoding after the reception.

[0284] In an example, as shown in FIG. 6, 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 Gap between the transmission of the two transmission blocks. The interval can be implicitly indicated by a low level.

[0285] In another example, as shown in FIG. 7, 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, the second transmission block is transmitted on the second carrier frequency f2, and there is a certain interval Gap between the transmission of the two transmission blocks. The interval can be implicitly indicated by a low level.

[0286] In some embodiments, as shown in FIG. 8, the coded data sequence can be processed by repetition and frequency hopping.

[0287] The number of carrier frequencies is M, and M is an integer with the maximum value of 2. The data sequence after the convolutional encoding processing, the BPSK modulation processing and the repetition processing, for example, can be referred to as 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, the bits corresponding to 2, M+2,..., (N2-1)*M+2 in the repeated data sequence are transmitted on the second carrier frequency, and so on, until the bits corresponding to M, 2*M,..., (N2-1)*M+M in the repeated data sequence are transmitted on the Mth carrier frequency. N2 is the length of the data sequence after the convolutional encoding, the BPSK modulation and the repetition operation, that is, the repeated data sequence. N2 is divisible by M. The receiving end can receive data on the first carrier frequency and the second carrier frequency, independently perform demodulation and decoding on the received data on the first carrier frequency and the second carrier frequency, or combine the data on the two carrier frequencies to perform demodulation and decoding, obtain the coded data sequence, and then perform convolutional decoding on the coded data sequence to obtain the first data sequence.

[0288] Alternatively, the number of carrier frequencies is M, M is an integer with a maximum value of 2, and the number of repetitions is P, P is an integer greater than or equal to 1. The entire convolutional coded and BPSK modulated data sequence, i.e., the coded data sequence, can be subjected to repetition processing, and then the 1st, (N2-1)*M+1th corresponding bits in the coded and modulated and repeated data sequence, e.g., the repeated data sequence, can be transmitted on the 1st carrier frequency, the 2nd, (N2-1)*M+2th corresponding bits in the coded data sequence can be transmitted on the 2nd carrier frequency, and so on, until the Mth, (N2-1)*M+Mth corresponding bits in the coded data sequence can be transmitted on the Mth carrier frequency. N2 is the length of the data sequence after convolutional coding, BPSK modulation, and repetition, i.e., the length of the coded data sequence, and N2 is divisible by M. The receiver can receive data on the 1st and 2nd carrier frequencies, and can independently decode the received data on the 1st and 2nd carrier frequencies, or can combine the data on the 2nd carrier frequency and decode the combined data, to obtain the coded data sequence, and then perform convolutional decoding on the coded data sequence to obtain the 1st data sequence.

[0289] Alternatively, the number of carrier frequencies is M, M is an integer with a maximum value of 2, and the number of repetitions is P, P is an integer greater than or equal to 1. The entire convolutional coded and BPSK modulated data sequence, i.e., the coded data sequence, can be subjected to repetition processing, and then the 1st, (N2-1)*M+1th corresponding bits in the coded and modulated and repeated data sequence, e.g., the repeated data sequence, can be transmitted on the 1st carrier frequency, the 2nd, (N2-1)*M+2th corresponding bits in the coded data sequence can be transmitted on the 2nd carrier frequency, and so on, until the Mth, (N2-1)*M+Mth corresponding bits in the coded data sequence can be transmitted on the Mth carrier frequency. N2 is the length of the data sequence after convolutional coding, BPSK modulation, and repetition, i.e., the length of the coded data sequence, and N2 is divisible by M. The receiver can receive data on the 1st and 2nd carrier frequencies, and can independently decode the received data on the 1st and 2nd carrier frequencies, or can combine the data on the 2nd carrier frequency and decode the combined data, to obtain the coded data sequence, and then perform convolutional decoding on the coded data sequence to obtain the 1st data sequence.

[0290] In addition, similarly, the 1st transmission block is transmitted on the 1st carrier frequency f1, and the 2nd transmission block and the end symbol are transmitted on the 2nd carrier frequency f2, and there is a certain interval between the transmission of the two transmission blocks, which can be implicitly indicated by a low level. Alternatively, the 1st transmission block is transmitted on the 1st carrier frequency f1, the end symbol of the 2nd transmission block does not hop frequency, and the 2nd transmission block is transmitted on the 2nd carrier frequency f2, and there is a certain interval between the transmission of the two transmission blocks, which can be implicitly indicated by a low level.

[0291] In some embodiments, the code rate of convolutional coding, the number of repetitions, and the number of frequency hops can also be jointly coded and indicated. The indication information can be as shown in Table 5.

[0292] Table 5

[0293] Based on the above independent indication, it can be known that the convolutional coding code rate can be 1 / 4, 1 / 3, 1 / 2, 2 bits of indication information are required, the repetition number can be 1, 2, 4, 8, 16, 3 bits of indication information are required, the frequency hopping number can be 1, 2, 1 bit of indication information is required, and a total of 6 bits of indication information is required. In the case of joint coding indication, only 5 bits of information is required, which saves 1 / 6 of the overhead compared with 6 bits of information in the case of independent indication. In this way, the amount of indication information overhead can be saved by the joint coding indication mode.

[0294] In some embodiments, as shown in FIG. 9, the sending end can also perform Manchester coding and binary on-off keying modulation on the first data sequence based on the indication information to obtain an encoded data sequence.

[0295] The code rate used in Manchester coding can include 1 / 2, 1 / 4, and 1 / 8. When the code rate is 1 / 2, the input bit is 1, 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.

[0296] Further, the sending end can also perform repetition processing on the encoded data sequence based on the indication information to obtain a second data sequence and transmit the second data sequence.

[0297] The sending end can perform repetition processing on each bit in the encoded data sequence or perform repetition processing on the entire encoded data sequence.

[0298] For example, when the repetition number P is 2, the first data sequence is b0b1b2b3b4b5b6b7, and the Manchester coding code rate is 1 / 2. After Manchester coding processing and binary on-off keying modulation processing on the first data sequence, the encoded data sequence 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 bit b i After coding modulation, c i,1 c i,2 , i = 0, 1,..., 7, and the length of the encoded data sequence N1 = 16. If each bit in the encoded data sequence is repeated, a second data sequence c 0,1 c0,1 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 , and the second data sequence length N2=32. Thus the second data sequence can be sent to the receiving end, and the receiving end can perform de-repetition processing on the second data sequence based on the indication information to obtain the encoded data sequence, and then perform demodulation and decoding processing on the encoded data sequence to obtain the first data sequence.

[0299] For another example, when the repetition number P is 2, the first data sequence is b0b1b2b3b4b5b6b7, and the encoding rate of the Manchester encoding is 1 / 2. After the Manchester encoding processing and the binary on-off keying modulation processing, the encoded data sequence 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 bits b i After the encoding and modulation, the c i,1 c i,2 , i=0, 1,..., 7, and the encoded data sequence length N1=16. If the encoded data sequence is processed as a whole, the second data sequence c 0,1 c 0,2c 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 N2=32. Thus the second data sequence can be sent to the receiving end, and the receiving end can perform de-repetition processing on the second data sequence based on the indication information to obtain an encoded data sequence, and then perform demodulation and decoding processing on the encoded data sequence to obtain the first data sequence.

[0300] In some embodiments, the encoded 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 repetition number is P, P is an integer greater than or equal to 1, and after the first data sequence is subjected to Manchester encoding processing, binary on-off keying modulation processing, and repetition processing, the data sequence, for example, the encoded data sequence, 1, M+1,...,(N2-1)*M+1 corresponding bits are transmitted on the first carrier frequency. The repetition processing can be bit-level repetition processing on the encoded data sequence, or repetition processing on the entire encoded data sequence. The 2, M+2,...,(N2-1)*M+2 corresponding bits in the encoded data sequence are transmitted on the second carrier frequency, and so on, until the M, 2*M,...,(N2-1)*M+M corresponding bits in the encoded data sequence are transmitted on the Mth carrier frequency. N2 is the length of the encoded data sequence, and N2 is divisible by P. The receiving end can receive data on the first carrier frequency and the second carrier frequency, and independently perform demodulation and decoding on the received data on the first carrier frequency and the second carrier frequency, or combine the data on the two carrier frequencies and perform demodulation and decoding to obtain the first data sequence.

[0301] In some embodiments, the coded data sequence can be processed by repetition and frequency hopping, 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, the first transmission block obtained after the Manchester coding processing, the binary on-off keying modulation processing and the repetition processing is transmitted on the first carrier frequency, and the second transmission block is transmitted on the second carrier frequency.

[0302] 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, which 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 hop frequency, the second transmission block is transmitted on the second carrier frequency f2, and there is a certain interval between the transmission of the two transmission blocks, which can be implicitly indicated by a low level.

[0303] In some embodiments, the coding information, the repetition information and the carrier frequency information in the indication information can be independently indicated or jointly encoded and indicated. In some embodiments, the indication information can be indicated by the control domain of the physical channel, the data domain of the physical channel, the medium access control signaling, the configured system information block information, or the corresponding manner of the predefined configuration information.

[0304] For example, the coding information of the Manchester coding in the indication information and the number of repetitions can be independently indicated.

[0305] For the code rate of the Manchester coding, 1-bit indication information can be used to indicate the Manchester coding. Bit "0" indicates that the Manchester coding is not enabled, and bit "1" indicates that the code rate of the Manchester coding is 1 / 2.

[0306] Alternatively, 1-bit indication information can be used to indicate the Manchester coding. Bit "0" indicates that the Manchester coding is not enabled, and bit "1" indicates that the code rate of the Manchester coding is 1 / 4.

[0307] Alternatively, 1-bit indication information can be used to indicate the Manchester coding. Bit "0" indicates that the Manchester coding is not enabled, and bit "1" indicates that the code rate of the Manchester coding is 1 / 4.

[0308] Alternatively, 2-bit indication information can be used to indicate the Manchester coding. Data sequence "00" indicates that the Manchester coding is not enabled, bit "01" indicates that the code rate of the Manchester coding is 1 / 2, data sequence "10" indicates that the code rate of the Manchester coding is 1 / 4, and bit "11" indicates that the code rate of the Manchester coding is 1 / 8.

[0309] For the repetition number, 3-bit indication information can be used to indicate the repetition number. Data sequence "000" represents that the repetition number is 1, data sequence "001" represents that the repetition number is 2, data sequence "010" represents that the repetition number is 4, data sequence "011" represents that the repetition number is 8, and data sequence "100" represents that the repetition number is 16.

[0310] For the carrier number, 1-bit indication information can be used to indicate the carrier number. Bit "0" represents that the carrier number is 1, and bit "1" represents that the carrier number is 2.

[0311] In some embodiments, the code rate of the Manchester coding and the repetition number in the indication information can be jointly coded and indicated. Exemplarily, the indication information can be as shown in Table 6.

[0312] Table 6

[0313] Alternatively, the code rate of the Manchester coding, the repetition number and the carrier number in the indication information can be jointly coded and indicated. The indication information can be as shown in Table 7.

[0314] Table 7

[0315] Based on the above independent indication, it can be known that the Manchester coding code rate can take values of 1 / 2, 1 / 4, 1 / 8, 2 bits of indication information are required, the repetition number can take values of 1, 2, 4, 8, 16, 3 bits of indication information are required, and the carrier number can take values of 1, 2, 1 bit of indication information is required, a total of 6 bits of indication information are required. In the case of joint coding and indication, only 4 bits of information are required, compared with 6 bits of information in the case of independent indication, 2 / 6 of the overhead is saved. In this way, by means of joint coding and indication, the amount of indication information overhead can be saved.

[0316] In some embodiments, the code rate of the Manchester coding, the repetition number and the frequency hopping number in the indication information can be jointly coded and indicated. Exemplarily, the indication information can be as shown in Table 8.

[0317] Table 8

[0318] Based on the above independent indication, it can be known that the Manchester coding code rate can be 1 / 2, 1 / 4, 1 / 8, 2 bits of indication information are required, the repetition number can be 1, 2, 4, 8, 16, 3 bits of indication information are required, the frequency hopping number can be 1, 2, 1 bit of indication information is required, and a total of 6 bits of indication information is required. In the case of joint coding indication, only 5 bits of information is required, which saves 1 / 5 of the overhead compared with the 5 bits of information of independent indication. In this way, the amount of indication information overhead can be saved by the joint coding indication mode.

[0319] In some embodiments, as shown in FIG. 9, the sending end can also perform convolutional coding, Manchester coding, and binary on-off keying modulation on the first data sequence based on the indication information to obtain an encoded data sequence.

[0320] The indication information can include a convolutional coding code rate, a Manchester coding code rate, a repetition number, a frequency hopping number, and a carrier number. The convolutional coding supported code rate can include 1 / 2, 1 / 3, 1 / 4, and the constraint length of the convolutional coding is 3 or 7. The Manchester coding code rate can include 1 / 2, 1 / 4, 1 / 8.

[0321] Further, the sending end can also perform repetition processing on the encoded data sequence based on the indication information to obtain a second data sequence and transmit the second data sequence.

[0322] The sending end can perform repetition processing on each bit in the encoded data sequence, or perform repetition processing on the entire encoded data sequence. The repetition number P is an integer greater than or equal to 1.

[0323] For example, when the repetition number P is 2, the first data sequence is b0b1b2b3b4b5b6b7, the convolutional coding code rate is 1 / 3, and the Manchester coding code rate is 1 / 2. After the first data sequence is processed by convolutional coding, Manchester coding, and binary on-off keying modulation, the encoded data sequence c 0,1 c 0,2 c 0,3 c 0,4 c 0,5 c 0,6, c 1,1 c 1,2 c 1,3 c 1,4 c 1,5 c 1,6 c 2,1 c 2,2 c 2,3 c 2,4 c 2,5 c 2,6 c 3,1 c 3,2 c 3,3c 3,4 c 3,5 c 3,6 c 4,1 c 4,2 c 4,3 c 4,4 c 4,5 c 4,6 c 5,1 c 5,2 c 5,3 c 5,4 c 5, 5c 5,6 c 6,1 c 6,2 c 6,3 c 6,4 c 6,5 c 6,6 c 7,1 c 7,2 c 7,3 c 7,4 c 7,5 c 7,6 Bit b i After encoding and modulation, c can be obtained i,1 c i,2 c i,3 c i,4 c i,5 c i,6 Let i = 0, 1, ..., 7, and the length of the encoded data sequence N1 = 48. If each bit in the encoded data sequence is processed repeatedly, a second data sequence c can be obtained. 0,1 c 0,1 c 0,2 c 0,2 c 0,3 c 0,3 c 0,4 c 0,4C0,5 c 0,5 c 0,6 c 0,6 c 1,1 c 1,1 c 1,2 c 1,2 c 1,3 c 1,3 c 1,4 c 1,4 c 1,5 c 1,5 c 1,6 c 1,6 c 2,1 c 2,1 c 2,2 c 2,2 c 2,3 c 2,3 c 2,4 c 2,4 c 2,5 c2,5 c 2, 6c 2,6 c 3,1 c 3,1 c 3,2 c 3,2 c 3,3 c 3,3 c 3,4 c 3,4 c 3,5 c 3,5 c 3,6 c 3,6 c 4,1 c 4,1 c 4,2 c 4,2 c 4,3 c 4,3 c 4,4 c 4,4 c 4,5 c 4,5 c 4,6 c 4,6 c 5,1 c 5,1 c 5,2 c 5,2 c 5,3 c 5,3 c 5,4 c 5,4 c 5,5 c5 ,5 c 5,6 c 5,6 c 6,1 c 6,1 c 6,2 c 6,2 c 6,3 c 6,3 c 6,4 c 6,4 c 6,5 c 6,5 c 6,6 c 6,6 c 7,1 c 7,1 c 7,2 c 7,2 c 7,3 c 7,3 c 7,4 c 7,4 c 7,5 c 7,5 c 7,6 c 7,6 , the second data sequence length N2=96. Thus the second data sequence can be sent to the receiving end, the receiving end can be based on the indication information on the second data sequence de-repetition processing, to obtain the encoded data sequence, and then the encoded data sequence is demodulated and decoded to obtain the first data sequence.

[0324] For example, when the repetition number P is 2, the first data sequence is b0b1b2b3b4b5b6b7, the code rate of the convolutional encoding is 1 / 3, and the code rate of the Manchester encoding is 1 / 2, the first data sequence is processed by the convolutional encoding, the Manchester encoding, and the binary on-off keying modulation to obtain the coded data sequence c 0,1 c 0,2 c 0,3 c 0,4 c 0,5 c 0,6, c 1,1 c 1,2 c 1,3 c 1,4 c 1,5 c 1,6 c 2,1 c 2,2 c 2,3 c 2,4 c 2,5 c 2,6 c 3,1 c 3,2 c 3,3 c 3,4 c 3,5 c 3,6 c 4,1 c 4,2 c 4,3 c 4,4 c 4,5 c 4,6 c 5,1 c 5,2 c 5,3 c 5,4 c 5, 5c 5,6 c 6,1 c 6,2 c 6,3 c 6,4 c 6,5 c 6,6 c 7,1 c 7,2 c 7,3 c 7,4 c 7,5 c 7,6 The bit b i After the encoding modulation, the coded data sequence c i,1 c i,2 c i,3 c i,4 c i,5 c i,6 , i = 0, 1,..., 7, and the length of the coded data sequence N1= 48. If the coded data sequence is processed by the repetition, the second data sequence c 0,1 c 0,2 c 0,3 c0,4 c 0,5 c 0,6, c 1,1 c 1,2 c 1,3 c 1,4 c 1,5 c 1,6 c 2,1 c 2,2 c 2,3 c 2,4 c 2,5 c 2,6 c 3,1 c 3,2 c 3,3 c 3,4 c 3,5 c 3,6 c 4,1 c 4,2 c 4,3 c 4,4 c 4,5 c 4,6 c 5,1 c 5,2 c 5,3 c 5,4 c 5, 5c 5,6 c 6,1 c 6,2 c 6,3 c 6,4 c 6,5 c 6,6 c 7,1 c 7,2 c 7,3 c 7,4 c 7,5 c 7,6 c 0,1 c 0,2 c 0,3 c 0,4 c 0,5 c 0,6, c 1,1 c 1,2 c 1,3 c 1,4 c 1,5 c 1,6 c 2,1 c 2,2 c 2,3 c 2,4 c 2,5 c 2,6 c 3,1 c 3,2 c 3,3 c 3,4 c 3,5 c 3,6 c 4,1 c 4,2 c4,3 c 4,4 c 4,5 c 4,6 c 5,1 c 5,2 c 5,3 c 5,4 c 5,5 c 5,6 c 6,1 c 6,2 c 6,3 c 6,4 c 6,5 c 6,6 c 7,1 c 7,2 c 7,3 c 7,4 c 7,5 c 7,6 The second data sequence has a length N2=96. Thus, the second data sequence can be transmitted to a receiving end, the receiving end can perform de-repetition processing on the second data sequence based on the indication information to obtain an encoded data sequence, and then perform demodulation and decoding processing on the encoded data sequence to obtain the first data sequence.
