Communication method and communication device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on April 3, 2024, with application number 202410409056.6 and application name “Communication Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of communications, and more specifically, to a communication method and a communication device. Background Art

[0003] With the increasing popularity of machine-type communication (MTC) and Internet of Things (IoT) communications in 5th generation mobile communication technology (5G) new radio (NR) systems, more and more IoT devices have been deployed in our lives. Some IoT devices are limited in size, and extending their operating time is difficult to achieve simply by increasing battery capacity. Therefore, to extend the battery life of terminal devices, it is necessary to reduce the power consumption of wireless communications. Among these components, the radio transceiver is one of the most power-hungry components in wireless communications.

[0004] Currently, there is a need for a method to reduce the power consumption of radio transceivers to overcome the cost, size, and power constraints of IoT devices. Given that FSK signals transition between high and low levels, using frequency shift keying (FSK) signals for communication is one approach to reducing radio transceiver power consumption. However, how network devices and end devices generate FSK signals remains unclear. Summary of the Invention

[0005] The embodiments of the present application provide a communication method and a communication device, which can enable a network device and a terminal device to generate an FSK signal.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, a communication method is provided. The method can be performed by a first device, or by a component of the first device, such as a processor, chip, or chip system of the first device, or by a logic module or software capable of implementing all or part of the functions of the first device. For example, in the case where the method can be performed by the first device, the method includes: the first device receiving first indication information, the first indication information indicating configuration parameters of a first signal, the configuration parameters including line code configuration parameters; and the first device sending a first signal, wherein the first signal is generated based on the configuration parameters of the first signal, and the first signal is a signal corresponding to a first sequence.

[0008] Optionally, the first signal in the embodiment of the present application may be, for example, an FSK signal.

[0009] In the communication method provided in an embodiment of the present application, a first device receives first indication information and can generate and transmit a first signal corresponding to a first sequence based on line code configuration parameters among the first signal configuration parameters indicated by the first indication information. Furthermore, the first indication information indicating the first signal configuration parameters can improve the flexibility of first signal generation.

[0010] In one possible implementation, the configuration parameter further includes a number of bit repetitions N of the first sequence, where N is a positive integer. In this solution, the configuration parameter includes the number of bit repetitions N of the first sequence, so that the first device generates the first signal based on the number of bit repetitions of the first sequence, which can improve the flexibility of the configuration parameters.

[0011] In this embodiment of the present application, the line code configuration parameters include a line code encoding scheme, which is a dual-phase space code (FM0) line code encoding scheme. In this solution, the line code encoding scheme is FM0, so that the first device generates the first signal according to the FM0 line code encoding scheme, which can improve the flexibility of generating the first signal.

[0012] In one possible implementation, the communication method provided in an embodiment of the present application further includes: a first device repeating each bit of the first sequence N times to generate a second sequence; and the first device encoding the second sequence according to the FM0 line coding method to generate a first signal. This solution can ensure that the first signal generated by the first device is a signal having a level switching characteristic within a unit time, and the number of switching times between coding bit 0 and coding bit 1 within the unit time has a multiple relationship.

[0013] In one possible implementation, N is an even number. This solution can make the first signal generated by the first device a signal having a level switching feature within a unit time, and the number of switching times between coding bit 0 and coding bit 1 within the unit time has an even multiple relationship.

[0014] In one possible implementation, in an embodiment of the present application, the starting level of the first signal is a high level or a low level. In this solution, once the starting level of the first signal is determined, it can correspond to a unique first signal, thereby reducing the coding complexity of the first device.

[0015] In a possible implementation, the starting level of the first signal is predefined. This solution can save the overhead of indication information indicating the starting level of the first signal.

[0016] In another possible implementation, the communication method provided in the embodiment of the present application further includes: the first device receiving second indication information, where the second indication information indicates the starting level of the first signal.

This solution can ensure that the first signal generated by the first device is a signal having a level switching characteristic within a unit time, and the number of switching times between coded bit 0 and coded bit 1 within the unit time is a multiple relationship.

[0020] In one possible implementation, Y is equal to M. In this solution, M and Y are equal, which can reduce the encoding complexity of the first device and save the overhead of indication signaling indicating M and Y respectively.

[0021] In one possible implementation, M and Y are even numbers. This solution can make the first signal generated by the first device a signal having a level switching characteristic within a unit time, and the number of switching times between coding bit 0 and coding bit 1 within a unit time has an even multiple relationship.

[0079] To facilitate the reader's understanding, the following describes the relevant technologies of the embodiments of this application:

[0080] 1. Characteristics of FSK signal.

[0081] Figure 1 is a schematic diagram of the time domain waveforms of information bit 1 and information bit 0 of an FSK signal. As shown in Figure 1, bit 1 has a single level transition within a time unit, which may correspond to frequency f1 on the spectrum; bit 0 has a double level transition within a time unit, which may correspond to frequency f2 on the spectrum. Where f1 is greater than f2, the time unit may be a time slot, a sub-time slot, or a symbol, or may be referred to as a bit window, etc. This is not limited in the present embodiment and will not be further described in the following description.

[0082] 2. Bi-phase space coding (FM0)

[0083] The FM0 encoding scheme uses level transitions within a time unit to represent information bits 0 and 1. The start bits of both information bits 0 and 1 each have a level transition, and the middle bit of information bit 0 has a level transition. Figure 2 shows a schematic diagram of the sequence generated using the FM0 encoding scheme. As shown in Figure 2, encoding the information bits using the FM0 encoding scheme yields two possible coded sequences. Exemplarily, encoding information bit 0 according to the FM0 encoding method can obtain a coded bit sequence 10 or 01; exemplary, encoding information bit 1 according to the FM0 encoding method can obtain a coded bit sequence 11 or 00; exemplary, encoding information bit 00 according to the FM0 encoding method can obtain a coded bit sequence 1010 or 0101; exemplary, encoding information bit 01 according to the FM0 encoding method can obtain a coded bit sequence 1011 or 0100; encoding information bit 10 according to the FM0 encoding method can obtain a coded bit sequence 1101 or 0010; encoding information bit 11 according to the FM0 encoding method can obtain a coded bit sequence 1100 or 0011.

[0084] 3. Manchester encoding.

[0085] The Manchester encoding scheme uses level transitions within a time unit to represent information bits 0 and 1. Information bits 0 and 1 are represented by level signals with opposite phases. Figure 3 is a schematic diagram of a sequence generated using the Manchester encoding scheme. As shown in Figure 3, encoding information bit 0 using the Manchester encoding scheme results in a coded bit sequence of 01, while encoding information bit 1 using the Manchester encoding scheme results in a coded bit sequence of 10.

[0086] 4. Ambient internet of things (A-IoT) devices.

[0087] A-IoT devices are a type of ultra-low-power IoT device, primarily categorized as active or passive. Active A-IoT devices are active tags or terminal devices that utilize the energy stored in their own energy storage modules to transmit wireless communication signals. Passive A-IoT devices (also known as passive tags) draw energy from external RF signals and communicate via backscattered RF signals, ultimately achieving ultra-low or even zero power consumption.

[0088] Compared with existing NR terminal devices (for example, R15, R16, and R17 NR terminals), A-IoT devices have at least one of the following characteristics:

[0089] 1) Maximum bandwidth: Less than the 100 MHz of R15 and R16, and less than the 20 MHz of R17 with reduced capability (RedCap). For example: 1 resource block (RB), 3 MHz.

[0090] 2) Number of antennas supported: one transmit and one receive, or one transmit and two receive.

[0091] 3) The uplink / device-to-reader transmission channel is not aligned with the boundaries of NR time slots, frames, symbols, etc.

[0092] 4) Uplink / device-to-reader transmission uses a single-carrier waveform.

[0093] 5) Downlink / reader-device transmission channels are not aligned with NR time slots, frames, symbols, etc.

[0094] 6) Downlink / reader-device transmission uses orthogonal frequency division multiplexing (OFDM) waveform.

[0095] 7) The supported modulation modes are at least one of binary on-off keying (OOK), FSK, and binary phase shift keying (BPSK).

[0124] It is understood that in the embodiments of the present application, each network element may perform some or all of the steps in the embodiments of the present application. These steps or operations are merely examples, and the embodiments of the present application may also perform other operations or variations of various operations.

[0125] Figure 8 is a schematic diagram of an example of a communication method provided in an embodiment of the present application. The method is described by taking the interaction between a first device and a second device as an example. Of course, the subject that executes the action of the first device in the method can also be a device / module of the first device, such as a chip, processor, or processing unit in the first device; the subject that executes the action of the second device in the method can also be a device / module in the second device, such as a chip, processor, or processing unit in the second device, etc., and the embodiment of the present application does not make specific limitations on this. For example, as shown in Figure 8, method 800 includes:

[0126] S810: The second device sends first indication information to the first device. Correspondingly, the first device receives the first indication information from the second device.

[0127] In the embodiment of the present application, the first indication information indicates the configuration parameters of the first signal. For example, the first signal can be an FSK signal or other signal, which is not limited in the embodiment of the present application.

[0128] In an embodiment of the present application, the first signal is a signal corresponding to the first sequence. Exemplarily, the first sequence can be called an information bit sequence, or the first sequence can also be other sequences, such as a channel coded bit sequence after channel coding the information bit sequence. The embodiment of the present application does not limit this. The embodiment of the present application takes the first sequence as an information bit sequence as an example to introduce the following embodiment. Exemplarily, the first signal can be a data signal or control information, wherein the control signal can be a preamble signal, or the control signal can also be a postamble signal, or an intermediate reference signal, etc. The embodiment of the present application does not limit this. It should be noted that the data signal, preamble signal, postamble signal, or intermediate reference signal signal transmitted at the same time adopts the same modulation and coding method. It should be understood that in a communication system, the information bit sequence is the most original uncoded sequence. It can be understood that channel coding is also called forward error correction code FEC. Exemplarily, the channel coding can be a convolutional code.

[0129] In one possible implementation, the configuration parameters of the first signal include at least one of the following: a line code configuration parameter, or a number N of bit repetitions of the first sequence. N is a positive integer. This solution enables the first device to generate the first signal based on the configuration parameters of the first signal, thereby increasing the flexibility of first signal generation.

[0130] In an embodiment of the present application, the line code configuration parameter includes a line code encoding method, which is the FM0 line code encoding method. In this solution, the line code encoding method is the FM0 line code encoding method, so that the first device generates the first signal according to the FM0 line code encoding method, which can improve the flexibility of generating the first signal.

[0131] Alternatively, optionally, in an embodiment of the present application, the second apparatus may not send the first indication information to the first apparatus, and the configuration parameters of the first information are predefined, for example, the predefined line code encoding mode is the FM0 line code encoding mode, and the predefined bit repetition number is 2. This solution can save the overhead of the indication information.

[0132] Optionally, in an embodiment of the present application, after the first device receives the first indication information from the second device, it can generate the first signal according to the configuration parameters of the first signal indicated by the first indication information.

[0133] In one possible implementation, when the configuration parameters of the first signal include the number of bit repetitions N of the first sequence and line code configuration parameters, and the line code configuration parameters include a line code encoding scheme, and the line code encoding scheme is the FM0 line code encoding scheme, in an embodiment of the present application, the first device generates the first signal by: repeating each bit of the first sequence N times to generate a second sequence; and encoding the second sequence according to the FM0 line code encoding scheme to generate the first signal. This solution can ensure that the first signal generated by the first device is a signal having a level switching characteristic within a unit time, and the number of switching times between code bit 0 and code bit 1 within the unit time is a multiple relationship.

[0134] Exemplarily, the second sequence may be referred to as a coded bit sequence, that is, an encoded sequence, or the second sequence may be other sequences, which is not limited in the embodiments of the present application.

[0135] In the embodiment of the present application, N can also be an even positive integer. This solution can make the first signal generated by the first device a signal having a level switching characteristic per unit time, and the number of switching times between coding bit 0 and coding bit 1 per unit time is an even multiple, that is, the first signal generated by the first device has the characteristics of an FSK signal, for example. For example, N is 2, which can reduce the time occupied by a single information bit in the time domain and improve transmission efficiency.

[0136] In an embodiment of the present application, the starting level of the first signal is a high level, or the starting level of the first signal may be a low level. In one possible implementation, the starting level of the first signal is predefined. For example, the starting level of the first signal is predefined to be a low level, or the starting level of the first signal is predefined to be a high level, or the starting level of the first signal is predefined to be a low level by predefining the starting level of the leading signal in the same transmission as the first signal to be a low level, or the starting level of the first signal is predefined to be a high level by predefining the starting level of the leading signal in the same transmission as the first signal to be a high level.

[0137] This solution can save the overhead of indication information. In another possible implementation, the communication method provided by the embodiment of the present application also includes: the second device sends the second indication information to the first device. Correspondingly, the first device receives the second indication information from the second device. The second indication information indicates the starting level of the first signal. In this way, the first device can determine the starting level of the first signal according to the indication of the second indication information. This solution is more flexible. After the starting level of the first signal is determined, it can correspond to the starting level of the unique leading signal and / or terminator signal in the same transmission as the first signal, so that the leading signal or terminator signal generated by the same sequence is unique, which can reduce the reception complexity of the second device and reduce the false detection rate of the second device in detecting the leading signal and / or terminator signal in the same transmission as the first signal.

[0138] For the two possible implementations described above, if the starting level of the first signal is predefined or indicated, the first device can determine a unique sequence corresponding to the preamble signal and / or terminator signal in the same transmission as the first signal. Otherwise, the first device needs to blindly detect the preamble signal and / or terminator signal in the same transmission as the first signal twice.

[0139] For example, FIG9 is a schematic diagram of a method for generating information bit 0 in a first sequence. As shown in FIG9 , N is 2. In one possible implementation, the starting level of the first signal is a high level, the first device repeats information bit 0 twice to obtain coded bit 00, and the first device then encodes coded bit 00 according to the FM0 encoding method to obtain a sequence corresponding to information bit 0 of 1010. In another possible implementation, the starting level of the first signal is a low level, the first device repeats information bit 0 twice to obtain coded bit 00, and the first device then encodes coded bit 00 according to the FM0 encoding method to obtain a sequence corresponding to information bit 0 of 0101.

[0140] For example, Figure 10 is a schematic diagram of a method for generating information bit 1 in a first sequence. As shown in Figure 10, N is 2. In one possible implementation, the starting level of the first signal is a high level, the first device repeats information bit 1 twice to obtain coded bit 11, and the first device then encodes coded bit 11 according to the FM0 encoding method to obtain a sequence corresponding to information bit 1 of 1100. In another possible implementation, the starting level of the first signal is a low level, the first device repeats information bit 1 twice to obtain coded bit 11, and the first device then encodes coded bit 11 according to the FM0 encoding method to obtain a sequence corresponding to information bit 1 of 0011.

[0141] The following describes the process of the first device generating the first signal with a specific example.

[0142] Exemplarily, the first sequence corresponding to the first signal or the information bits corresponding to the first signal are: 0101, and N is 2. This step includes:

[0143] The first device repeats the first information bit "0" in the first sequence twice to obtain "00", repeats the second information bit "1" twice to obtain "11", repeats the third information bit "0" twice to obtain "00", and repeats the fourth information bit "1" twice to obtain "11", then the second sequence is: 00110011.

[0144] The first device encodes the second sequence according to the FM0 line code encoding method to generate a first signal: 1010110010101100 (the starting level is a high level), or 0101001101010011 (the starting level is a low level).

[0145] In the embodiment of the present application, the number of bit repetitions can also be replaced by the code length of the line code or the code length of the FM0 code, which is not limited in the embodiment of the present application. In this embodiment, the first device can directly generate the first signal based on the code length of the line code or the code length of the FM0 code.

[0146] For example, Figure 11 is a schematic diagram illustrating a method for generating information bit 0 in a first sequence. As shown in Figure 11, the code length of the line code or the code length of the FM0 encoding is 2. In one possible implementation, the starting level of the first signal is high, and the first device obtains a sequence corresponding to information bit 0 of 1010 based on the code length of the line code or the code length of 2 of the FM0 encoding. In another possible implementation, the starting level of the first signal is low, and the first device obtains a sequence corresponding to information bit 0 of 0101 based on the code length of the line code or the code length of 2 of the FM0 encoding.

[0147] For example, Figure 12 is a schematic diagram illustrating a method for generating information bit 1 in a first sequence. As shown in Figure 12, the code length of the line code or the code length of the FM0 encoding is 2. In one possible implementation, the starting level of the first signal is high, and the first device obtains a sequence corresponding to information bit 1 as 1100 based on the code length of the line code or the code length of 2 of the FM0 encoding. In another possible implementation, the starting level of the first signal is low, and the first device obtains a sequence corresponding to information bit 1 as 0011 based on the code length of the line code or the code length of 2 of the FM0 encoding.

[0148] In another possible implementation, the configuration parameters of the first signal include line code configuration parameters, which may include at least one of the following: a line code encoding mode, a number of repetitions M of the first repetition mode, or a number of repetitions Y of the second repetition mode. M and Y are positive integers. In this solution, the configuration parameters include the number of repetitions M of the first repetition mode and / or the number of repetitions Y of the second repetition mode, so that the first device generates the first signal based on M and / or Y, thereby improving the flexibility of generating the first signal.

[0149] In the embodiment of the present application, the line code encoding method is the Manchester line code encoding method. In this solution, the line code encoding method is the Manchester line code encoding method, so that the first device generates the first signal according to the Manchester line code encoding method, which can improve the flexibility of generating the first signal.

[0150] In the embodiment of the present application, the first repetition mode is to repeat the third sequence obtained by encoding bit 0 in the first sequence according to the Manchester line code encoding mode, and the second repetition mode is to repeat each coded bit in the fourth sequence obtained by encoding bit 1 in the first sequence according to the Manchester line code encoding mode.

[0151] Optionally, in an embodiment of the present application, the second device may not send the first indication information to the first device, and the configuration parameters of the first information are predefined. For example, the predefined line code encoding method is Manchester encoding, the number of repetitions of the first repetition method is 2, and the number of repetitions of the second repetition method is 2. This solution can save the overhead of the indication information.

[0152] In one possible implementation, when the configuration parameters of the first signal include line code configuration parameters, which include a line code encoding scheme, a number of repetitions (M) of a first repetition scheme, and a number of repetitions (Y) of a second repetition scheme, and when the line code encoding scheme is Manchester line code, in this embodiment of the present application, generating the first signal by the first device includes: encoding the first sequence according to the Manchester line code encoding scheme to obtain a fifth sequence; repeating the third sequence M times if the fifth sequence includes one or more third sequences; and repeating each coded bit in the fourth sequence Y times if the fifth sequence includes one or more fourth sequences to generate the first signal. The fifth sequence includes at least one of the following: one third sequence, one fourth sequence, multiple third sequences, or multiple fourth sequences, the third sequence being a sequence obtained by encoding bit 0 in the first sequence according to the Manchester line code encoding scheme, and the fourth sequence being a sequence obtained by encoding bit 1 in the first sequence according to the Manchester line code encoding scheme. This solution enables the first signal generated by the first device to be a signal having a level switching characteristic within a unit time, and wherein the number of switchings between coded bit 0 and coded bit 1 within a unit time is a multiple relationship.

[0153] Illustratively, the third sequence, the fourth sequence, and the fifth sequence may be referred to as coded bit sequences, i.e., coded sequences. Alternatively, the third sequence, the fourth sequence, and the fifth sequence may also be other sequences, which is not limited in the embodiments of the present application.

[0154] In the embodiment of the present application, M and Y may also be even numbers among positive integers. This solution can make the first signal generated by the first device a signal having a level switching characteristic within a unit time, and the number of switching times between coding bit 0 and coding bit 1 within a unit time has an even multiple relationship, that is, the first signal generated by the first device has the characteristics of, for example, an FSK signal.

[0155] M and Y may be equal or unequal. When M and Y are equal, the encoding complexity of the first device and the decoding complexity of the second device can be reduced, and the signaling overhead of indicating M and Y can be saved. For example, M and Y can be 2, which can reduce the time occupied by a single information bit in the time domain and improve transmission efficiency.

[0156] For example, Figure 13 is a schematic diagram illustrating a method for generating information bit 0 in a first sequence. As shown in Figure 13 , M is 2. The first device encodes information bit 0 using the Manchester encoding scheme to obtain a third sequence 01. The first device then repeats the third sequence 01 twice using the first repetition scheme to obtain a sequence 0101 corresponding to information bit 0.

[0157] For example, Figure 14 is a schematic diagram illustrating a method for generating information bit 1 in a first sequence. As shown in Figure 14 , Y is 2, and the first device encodes information bit 1 using the Manchester encoding scheme to obtain a fourth sequence 10. The first device then repeats each encoded bit in the fourth sequence twice using the second repetition scheme to obtain a sequence corresponding to information bit 1, which is 1100.

[0158] The following describes the process of the first device generating the first signal with a specific example.

[0159] Exemplarily, the first sequence corresponding to the first signal or the information bits corresponding to the first signal are: 0110, M is 2, and Y is 2. This step includes:

[0160] The first device encodes the first information bit 0 in the first sequence according to the Manchester encoding method to obtain a first third sequence 01, the first device encodes the second information bit 1 in the first sequence according to the Manchester encoding method to obtain a first fourth sequence 10, the first device encodes the third information bit 1 in the first sequence according to the Manchester encoding method to obtain a second fourth sequence 10, and the first device encodes the fourth information bit 0 in the first sequence according to the Manchester encoding method to obtain a second third sequence 01.

[0161] The first device repeats the first third sequence twice to obtain 0101, repeats each coded bit in the first fourth sequence twice to obtain 1100, repeats each coded bit in the second fourth sequence twice to obtain 1100, and repeats the second third sequence twice to obtain 0101, and finally generates a first signal of 0101110011000101.

[0162] In the embodiment of the present application, the first repetition mode can be replaced by M repetition, and the second repetition mode can be replaced by chip repetition, or the first repetition mode can be replaced by the code length M of the line code or the code length M of Manchester encoding, and the second repetition mode can be replaced by chip length extension or chip length scaling, which is not limited in the embodiment of the present application. Wherein, a chip is a time unit, and its size is less than or equal to the NR OFDM symbol corresponding to the 15kHz subcarrier spacing.

[0163] Alternatively, as a possible implementation method, the line code encoding method included in the line code configuration parameters may also be other encoding methods, and the line configuration parameters may also include other configuration parameters, as long as the first device can generate the first information according to these parameters. This embodiment of the present application does not limit this.

[0164] In an embodiment of the present application, the first indication information is carried in a unicast message, or the first indication information is carried in a broadcast message. This solution can enable the second device to send the first indication information through a unicast message or a broadcast message, so that the first device can obtain the first indication information through a unicast message or a broadcast message. Exemplarily, the first indication information is carried in a system message, or the first indication information is carried in a paging message, or the first indication information is carried in scheduling information sent by the second device to the first device, or the first indication information is carried in a high-layer signaling MAC CE. S820, the first device sends a first signal to the second device. Accordingly, the second device receives the first signal from the first device.

[0165] In the embodiment of the present application, after receiving the first signal from the first device, the second device may decode the first signal according to the first indication information to obtain a first sequence.

[0166] In one possible implementation, parsing the first sequence corresponding to the first signal according to the FM0 coding scheme by the second device includes: decoding the first signal according to the FM0 line coding scheme by the second device to obtain a second sequence; and removing N repetitions from the second sequence by the second device to obtain the first sequence. That is, the process of parsing the first signal by the second device is the inverse of the process of generating the first signal by the first device.

[0167] Corresponding to the above example, the first signal is 0101001101010011 (the starting level is a low level), or 1010110010101100 (the starting level is a high level), and N is 2. The step of the second device parsing the first signal includes:

[0168] The second device decodes 010110010101100, or 0101001101010011 according to the FM0 line code encoding method to obtain a second sequence of 00110011.

[0169] The second device removes 2 repetitions from the second sequence to obtain a first sequence of 0101.

[0170] In another possible implementation, the second device parses the first sequence corresponding to the first signal according to the Manchester line code encoding scheme, including: when the first signal includes one or more sixth sequences, the second device removes M repetitions of the sixth sequence according to the first repetition scheme; and when the first signal includes one or more seventh sequences, the second device removes Y repetitions of each coded bit of the seventh sequence according to the second repetition scheme to obtain a fifth sequence, where the fifth sequence includes at least one of the following: one third sequence, one fourth sequence, multiple third sequences, or multiple fourth sequences; and the second device decodes the fifth sequence according to the Manchester line code encoding scheme to obtain the first sequence.

[0171] Corresponding to the above example, the first signal is 0101110011000101, M is 2, and Y is 2. The step of the second device parsing the first signal includes:

[0172] The second device removes two repetitions from the first sixth sequence 0101 according to the first repetition pattern to obtain a first third sequence 01. The second device removes two repetitions from the first seventh sequence according to the second repetition pattern to obtain a first fourth sequence 10. The second device removes two repetitions from the second seventh sequence according to the second repetition pattern to obtain a second fourth sequence 10. The second device removes two repetitions from the second sixth sequence according to the first repetition pattern to obtain a second third sequence 01, i.e., a fifth sequence of 01101001. Furthermore, the second device decodes the fifth sequence according to the Manchester line code encoding method to obtain a first sequence of 0110.

[0173] In the communication method provided in the embodiment of the present application, the first device receives the first indication information and can generate and send the first signal corresponding to the first sequence according to the line code configuration parameters in the configuration parameters of the first signal indicated by the first indication information, thereby improving the flexibility of the first signal generation.
