In order to facilitate a better understanding of the embodiments of the present application, the technologies related to the present application are explained. (1) Low power receiver. The 3rd Generation Partnership Project (3GPP) began research on introducing a low-power wake-up receiver (LP-WUR) / low-power wake-up signal (LP-WUS) in mobile cellular systems in Release 18 (Rel-18). The basic operating principle is that the receiving end includes a first module and a second module. As shown in Figure 2, the first module is the main communication module (MR), which is used to transmit and receive mobile communication data, and the second module is the low-power wake-up receiving module, which is used to receive the wake-up signal. In energy-saving mode, the terminal turns on the low-power receiving module to listen for the low-power wake-up signal (LP-WUS) and turns off the main communication module. When downlink data arrives, the network sends a wake-up signal to the terminal. After the terminal detects the wake-up signal through the low-power receiving module, it triggers the main communication module to switch from off to on after a series of judgments (at which point the low-power receiving module switches from the working state to the off state). The low-power wake-up receiving module can be turned on continuously or intermittently, and can receive the low-power wake-up signal when turned on. Low-power receivers can be divided into multiple types, for example, including first-type low-power receivers and second-type low-power receivers. The first type of low-power receiver has the ability to demodulate the first type of waveform, but does not have the ability to demodulate the second type of waveform. For example, the first type of waveform is a waveform based on on-off keying (OOK), and the second type of waveform is a waveform based on orthogonal frequency division multiplexing (OFDM). The second type of low-power receiver has the ability to detect the second type of waveform, and the second type of low-power receiver may have the ability to demodulate the first type of waveform, or may not have the ability to demodulate the first type of waveform. Low-power receiver structures can be divided into several types. For example, the first type of low-power receiver may include: a receiver based on RF detection as shown in Figure 3, a receiver based on intermediate frequency envelope detection as shown in Figure 4, and a receiver based on zero intermediate frequency baseband envelope detection as shown in Figure 5. These low-power receiver structures generally have low power consumption and can at least be used for demodulating on-off keying signals. In addition, these low-power receiver structures can be added with a module for demodulating frequency-shift keying (FSK) signals to support FSK signal demodulation. The second type of low-power receiver supports signal detection based on OFDM waveform, and its structure has at least some modules different from the structure of the first type of low-power receiver. For example, the second type of low-power receiver can process the real and imaginary signals separately. The signal processing can be sequence correlation processing. For example, the second type of low-power receiver may include: a low-power receiver that can be used for OFDM signal reception as shown in Figure 6, and a low-power receiver detection module based on time domain correlation (without Fast Fourier Transform (FFT)) that can be used for OFDM signal reception as shown in Figure 7. The low-power receiver of this architecture usually consumes more power than the receivers of Figures 3 to 5, but is also lower than the power consumption of MR. (2) Signals monitored by low-power receivers. Different types of low-power receivers can monitor different signals. For example, the signals monitored by the first type of low-power receiver mentioned above are based on OOK waveforms. These can include OOK-based LP-WUS and OOK-based synchronization signals (LP Synchronization Signal, LP-SS). Figure 8 shows a schematic diagram of OOK waveform-based signals. As shown in Figure 8, these signals are relatively simple on-off keying signals, allowing the receiver to achieve synchronization, perform measurements, or receive wake-up notifications through simple energy detection and subsequent possible sequence detection and identification processes. For another example, the signals monitored by the second type of low-power receiver mentioned above include at least signals based on OFDM waveforms. The signals monitored by the second type of low-power receiver include LP-WUS based on OFDM. For example, LP-WUS based on OOK with an OFDM sequence superimposed on the OOK symbol (OOK based LP-WUS with overlaid OFDM sequence(s)over OOK symbol). The signals monitored by the second type of low-power receiver may also include synchronization signals based on OFDM, such as the Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS) in the existing New Radio (NR) system. (3) Information carried by LP-WUS based on OOK. The network-side device can send LP-WUS to the terminal. The LP-WUS signal can carry information used to wake up the terminal to receive paging. For example, LP-WUS can carry information used to wake up a UE in the idle / inactive state of Radio Resource Control (RRC) to receive paging information, to which the UE belongs (LP-WUS indicates the subgroup the UE belongs to monitor its associated paging), or LP-WUS can carry information used to wake up a UE in the connected state of RRC to monitor the physical downlink control channel (PDCCH), the subgroup of the UE or the UE's unique identification information. The information carried by the LP-WUS can be transmitted in different ways. Specifically, it can be transmitted in the following ways: Method 1: The information of the subgroup to which the UE belongs or the identification information unique to the UE carried by the LP-WUS may be represented by a specific sequence. For example, standard predefined or network configuration N ook sequences, each sequence corresponds to a subgroup index. For example, the network configuration is used to wake up users to receive paging messages using Ng=8 subgroups, and the standard predefines or the network configures 8 OOK sequences, sequence 1, sequence 2, ..., sequence 8. The one-to-one correspondence between the subgroup number i where the user is located and the OOK sequence j is predefined by the standard or configured by the network. For example, the network-side device sends the corresponding OOK sequence i according to the subgroup number i where the user currently needs to be awakened is located. Alternatively, the standard predefines or the network configures 9 OOK sequences, sequence 1, sequence 2, ..., sequence 8, sequence 9. The subgroup number i where the user is located wakes up all users at the same time, and the one-to-one correspondence with the OOK sequence j is predefined by the standard or configured by the network. For example, the network-side device sends the corresponding OOK sequence i according to the subgroup number i where the user currently needs to be awakened is located, or sends OOK sequence 9 to wake up all users. The numbering of OOK sequence i can also start from 0. For another example, the network configures Ng=8 subgroups for waking up users to receive paging messages, and the network configures N ook Each sequence corresponds to waking up one or more subgroups. ook = 256, each sequence corresponds to waking up 1, 2...8 subgroups in 8 subgroups at a time. For example, N ook Can be less than 256, with N ook=64 as an example, the network configuration or standard pre-defines a combination of wake-up subgroups corresponding to each sequence. To ensure performance, N ook The sequences usually need to satisfy the requirement that the cross-correlation value between the sequences is low. To improve performance, each bit of the OOK sequence can be encoded. For example, using Manchester encoding, a bit '0' in the OOK sequence is represented by two OOK elements (chips): an OOK on element and an OOK off element, or an OOK off element and an OOK on element. A bit '1' is represented by two OOK elements (an OOK off element and an OOK on element, or an OOK on element and an OOK off element). Method 2: The information of the subgroup to which the UE belongs or the identification information specific to the UE carried by the LP-WUS may be represented by the transmitted information bits. For example, the network configures Ng=8 subgroups for waking up users to receive paging messages. 8 bits can be used to indicate any one or more of the 8 subgroups (usually such an indication method is called a bitmap), where each bit corresponds to one subgroup. To improve performance, information bits can be encoded. For example, using Manchester encoding, a bit '0' is represented by two OOK elements (one OOK ON element and one OOK OFF element, or one OOK OFF element and one OOK ON element), and a bit '1' is represented by two OOK elements (one OOK OFF element and one OOK ON element, or one OOK ON element and one OOK OFF element). Alternatively, the network configures a UE-specific identifier for each UE, such as a 16-bit Cell Radio Network Temporary Identifier (C-RNTI). 16 bits can be used to indicate the C-RNTI, where each bit corresponds to each bit in the C-RNTI. It should be noted that the waveforms of the low power wake-up signals (LP-WUS) supported by different low power receivers may be different. For example, the signal monitored by the first type of low power receiver mentioned above is an LP-WUS based on an OOK waveform, and the signal monitored by the second type of low power receiver mentioned above is an LP-WUS based on an OFDM waveform. Although method one or method two can be used to carry the wake-up information through the OOK sequence carried on the LP-WUS, it is not clear how to transmit the wake-up information through the OFDM sequence carried by the LP-WUS. In an embodiment of the present application, by carrying the OFDM sequence on the OOK sequence, that is, the signal monitored by the second type of low power receiver is an LP-WUS with an OFDM sequence superimposed on the OOK symbol (OOK based LP-WUS with overlaid OFDM sequence(s)over OOK symbol), and the wake-up information is transmitted through the OOK sequence and the OFDM sequence respectively, thereby improving the transmission efficiency of the wake-up information. The signal transmission method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings. FIG9 is a schematic flowchart of a signal transmission method 200 according to an embodiment of the present application. As shown in FIG9 , the signal transmission method 200 may include at least part of the following contents: S210: A first terminal receives a first signal from a network-side device. S220: The first terminal determines target information based on the first signal. The first signal carries a first sequence based on on-off keying (OOK), at least one on symbol in the first sequence carries at least one second sequence, and the target information is determined based on a first information bit determined based on at least one of the at least one second sequence and the at least one on symbol. Exemplarily, the at least one opening symbol and the at least one second sequence may be one-to-one, many-to-one or one-to-many. Exemplarily, the second sequence may be a complex signal sequence. For example, the second sequence may be an OFDM sequence, that is, the first signal may be an OOK based signal with overlaid OFDM sequence(s) over OOK symbol. Exemplarily, a network side device (such as a network node) sends the first signal. The first signal sent by the network side device may be an on-off keying signal (OOK signal). The first signal may also carry at least one second sequence, such as a complex signal sequence (such as an OFDM sequence). For example, the complex signal sequence is modulated on the ON symbol of the OOK signal, where the complex signal sequence is, for example, a time domain signal before discrete Fourier transform (DFT); or, the complex signal sequence is modulated on an OFDM symbol, where the complex signal sequence is, for example, a frequency domain signal before inverse fast Fourier transform (IFFT). Optionally, the complex signal sequence in the first signal is a complex sequence determined according to at least one item or a sequence determined by a real or complex sequence generated (such as multiplied) by at least two of the following: an M sequence, a ZC sequence, a gold sequence, a constant envelope zero autocorrelation sequence (CAZAC) sequence. In addition, the complex signal sequence may include a sequence generated by constellation points corresponding to one or more of the following modulation modes: binary phase shift keying (BPSK), pi / 2 BPSK, quadrature phase shift keying (QPSK), 16 quadrature amplitude modulation (QAM), 64QAM, 256QAM, 1024QAM, 4096QAM, etc. The M sequence or gold sequence may be a unipolar representation, such as each element taking a value of 0 or 1, or a bipolar representation, such as each element taking a value of ±1. Optionally, the multiplication of the two sequences may be the Kronecker product of the two sequences, for example, one sequence is a ZC sequence of length 12 and the other sequence is [1 1 1], and the Kronecker product of the two sequences is a complex sequence of length 36. Optionally, the complex sequence may be an upsampled sequence of a sequence. For the convenience of description, OFDM sequence is used in the following description to represent a complex signal sequence, but the present invention is not limited thereto. Exemplarily, when the first information bit is determined based on the at least one second sequence, the at least one second sequence corresponds to the first information bit, and the first information bit is used to indicate the target information. That is, the information bit corresponding to the at least one second sequence indicates the target information. For example, assuming that the information bits corresponding to the at least one second sequence are X=4 information bits X inf =[X inf1, Xinf2 ,X inf3 ,X inf4 ], the information bit X inf Used to indicate information A i . Among them, the candidate sequence corresponding to the open symbol and the information bit X inf The corresponding relationship between the information bit X inf and the information A i The correspondence between them can be predefined by the standard or configured by the network side device, and the candidate sequence corresponding to the opening symbol includes the at least one second sequence. Accordingly, after receiving the first sequence, the second terminal can determine the corresponding information bit X according to the at least one second sequence carried by the received first sequence. inf , and then based on the information bit X inf Determine the information A it indicates i For example, the information A i is the subgroup index i that needs to be awakened, that is, it is used to awaken the UE of subgroup index i or all UEs. Assume that there are 4 candidate sequences corresponding to an open symbol, and 2 bits of information bits can be transmitted through a candidate sequence. Assume that X inf It contains 8 bits, where the relationship between every 2 bits and the candidate sequence can be determined by Table 1. Table 2 gives the information bit X inf and the information A i A specific example of the correspondence between . Table 1 It should be understood that the values ​​of the candidate sequences and information bits corresponding to the open symbols shown in Table 1 are merely examples and should not be construed as limiting the present application. For example, the number of candidate sequences corresponding to the open symbols may be greater than or less than 4. For example, when the number of candidate sequences corresponding to the open symbols is greater than 4, the number of information bits corresponding to the candidate sequences corresponding to the open symbols is greater than 2. Table 2 It should be understood that the information bits X shown in Table 2 inf The values ​​and corresponding subgroup indexes are merely examples and should not be construed as limitations on the present application. For example, 1000 can be replaced by any value other than 0000 to 0111. Of course, in other alternative embodiments, the bits corresponding to the at least one second sequence may also be bits of a specific OOK sequence, and the specific OOK sequence is used to indicate the target information. For example, the bits corresponding to the at least one second sequence may also be used to wake up the OOK sequence S of the UE subgroup 0. ook_0 =[0 1 0 1 0 0 1 1], that is, the at least one second sequence corresponds to these 8 bits. Exemplarily, when the first information bit is determined based on the at least one second sequence and the at least one open symbol, the positions of the at least one second sequence and the at least one open symbol are used to determine the first information bit. For example, the first information bit is obtained by concatenating the information bits corresponding to the position of the at least one open symbol with the information bits corresponding to the at least one second sequence. In this embodiment, at least one open symbol in the first sequence carries at least one second sequence, and the target information is determined based on a first information bit determined based on at least one second sequence and at least one item of the at least one open symbol, which is equivalent to being able to realize information transmission based on other types of sequences carried on the OOK sequence, thereby making the OOK sequence suitable for terminals with different receiver capabilities. In some embodiments, when the first signal is a wake-up signal, the target information is information used to indicate a terminal to be woken up; or when the first signal is a synchronization signal, the target information is information used for synchronization or measurement of the first terminal. Exemplarily, when the first signal is a wake-up signal, the target information is information used to indicate the terminal to be awakened; equivalently, the first signal is an LP-WUS based on OOK with an OFDM sequence superimposed on an OOK symbol, which is used to wake up the main receiver through the low-power receiver of the first terminal. Exemplarily, when the first signal is a synchronization signal, the target information is information used for synchronization or measurement of the first terminal; equivalently, the first signal is an LP-SS based on OOK with an OFDM sequence superimposed on the OOK symbol, such as LP-PSS or LP-SSS. Of course, in other alternative embodiments, the first signal may also be other low-power signals other than LP-WUS and LP-SS, and this application does not make any specific limitation on this. In some embodiments, bits of a specific sequence carried by the first sequence are used to indicate the target information, or information bits carried by the first sequence are used to indicate the target information. Exemplarily, the bits of the specific sequence carried by the first sequence are used to indicate the target information. For example, assuming that the first sequence is a specific OOK sequence S ook_i =[S o1_i, S o2_i, ….S oL_i ], each element S of the OOK sequence oj_i Corresponds to an OOK ON or OOK OFF symbol. For the convenience of description, S oj_i =1 corresponds to OOK ON symbol, S oj_i=0 corresponds to the OOK OFF symbol. The network side device sends a specific OOK sequence S to the first terminal. ook_i is a bit stream of length L, corresponding to information A i The specific OOK sequence is an OOK sequence in a sequence set, and the sequence set is predefined by a standard or configured by a network side device. The information A i With the OOK sequence S ook_i The corresponding relationship is predefined by the standard or configured by the network side device. Accordingly, after the first type of low-power receiver mentioned above receives one or more OOK sequences in the sequence set, it can determine the information A indicated by the received OOK sequence. i . With information A i Taking the subgroup index i that the network needs to wake up as an example, that is, waking up the UE of the subgroup index i or waking up all UEs, the bits of the specific sequence carried by the first sequence are used to indicate the subgroup index i that needs to be woken up. For example, the standard predefined or network configuration has N ook sequences, each sequence corresponds to a subgroup index. For example, the network configuration is used to wake up users to receive paging messages using Ng=8 subgroups, and the standard predefines or the network configures 8 OOK sequences, sequence 1, sequence 2, ..., sequence 8. The one-to-one correspondence between the subgroup number i where the user is located and the OOK sequence j is predefined by the standard or configured by the network. For example, the network-side device sends the corresponding OOK sequence i according to the subgroup number i where the user currently needs to be awakened is located. Alternatively, the standard predefines or the network configures 9 OOK sequences, sequence 1, sequence 2, ..., sequence 8, sequence 9. The subgroup number i where the user is located wakes up all users at the same time, and the one-to-one correspondence with the OOK sequence j is predefined by the standard or configured by the network. For example, the network-side device sends the corresponding OOK sequence i according to the subgroup number i where the user currently needs to be awakened is located, or sends OOK sequence 9 to wake up all users. The numbering of OOK sequence i can also start from 0. For example, Table 3 shows the subgroup index i and OOK sequence S ook_i A specific example of the correspondence. Table 3 It should be understood that the subgroup indexes shown in Table 3 are merely examples and should not be construed as limiting the present application. According to another implementation, the “subgroup index i” in Table 2 can be replaced by the OOK sequence S ook_i Then, combined with Table 3, the information bit X in Table 2 can be determined inf and the information A i The correspondence between them. For another example, the network configures Ng=8 subgroups for waking up users to receive paging messages, and the network configures N ook Each sequence corresponds to waking up one or more subgroups. ook = 256, each sequence corresponds to waking up 1, 2...8 subgroups in 8 subgroups at a time. For example, N ook Can be less than 256, with N ook =64 as an example, the network configuration or standard pre-defines a combination of wake-up subgroups corresponding to each sequence. To ensure performance, N ook The sequences usually need to satisfy the requirement that the cross-correlation value between the sequences is low. Exemplarily, the information bits carried by the first sequence are used to indicate the target information. For example, assuming that the information bits carried by the first sequence include X=4 information bits X inf =[X inf1, X inf2 ,X inf3 ,X inf4 ], which corresponds to information A i The information A i With the information bit X inf The corresponding relationship is predefined by the standard or configured by the network side device. inf Determine the information A it indicates i . With information A i Take the subgroup index i that needs to be awakened as an example, that is, to awaken the UE of subgroup index i or to awaken all UEs. Assume X inf Contains 4 bits. Table 2 mentioned above gives the subgroup index i and information bit X inf A specific example of the correspondence. It should be noted that the information bits carried by the first sequence may also be a bitmap or a terminal identifier, such as a C-RNTI, which is not specifically limited in this application. In this embodiment, bits of a specific sequence carried by the first sequence are used to indicate the target information, or information bits carried by the first sequence are used to indicate the target information. This allows the first sequence and the at least one sequence to transmit the same information. That is, terminals with different receiver capabilities can determine the target information by receiving the first signal, thereby improving information transmission efficiency. In some embodiments, the bits of the specific sequence are different from the first information bits, or the information bits carried by the first sequence are the same as or different from the first information bits. Exemplarily, the bits of the specific sequence are different from the first information bits. If the first signal is an LP-WUS based on OOK with an OFDM sequence superimposed on an OOK symbol, it means that the 0 and 1 bits obtained by the LP-WUR terminal supporting OFDM sequence detection and the LP-WUR terminal supporting OOK detection when receiving the same LP-WUS are different, but the target information indicated by the obtained 0 and 1 bits needs to be the same. Exemplarily, when the information bits carried by the first sequence and the first information bits are the same, they may be indication information of the target information. For example, the information bits carried by the first sequence and the first information bits are both X inf =[X inf1, X inf2 ,X inf3 ,X inf4 ] to wake up the UEs of any one or all of the Ng subgroups to receive paging information. Exemplarily, the information bits carried by the first sequence are the same as or different from the first information bits. If the first signal is an LP-WUS based on OOK with an OFDM sequence superimposed on an OOK symbol, it means that the 0 and 1 bits obtained by the LP-WUR terminal supporting OFDM sequence detection and the LP-WUR terminal supporting OOK detection when receiving the same LP-WUS may be the same or different, but the target information indicated by the obtained 0 and 1 bits needs to be the same. In some embodiments, the encoding method used for the bits carried by the first sequence is the same as or different from the encoding method used for the first information bits. For example, when the second sequence is an OFDM sequence, considering that the OFDM sequence detection performance is generally better than the demodulation performance of the first sequence based on OOK, in order to improve the performance of the first sequence, the information bits X carried by the first sequence are inf Manchester coding may be combined. The first information bit does not need to be coded. Alternatively, the information bit X carried by the first sequence inf It can be combined with Manchester coding, and the first information bit can also be combined with Manchester coding, but the coding rate can be different. In some embodiments, when at least one of the following conditions is met, bits of a specific sequence carried by the first sequence are used to indicate the target information: The number of bits of the target information is less than or equal to a preset threshold; The first terminal is in a Radio Resource Control (RRC) idle state or an RRC deactivated state; The first terminal is configured with first indication information, where the first indication information indicates that bits of a specific sequence carried by the first sequence are used to indicate the target information. Exemplarily, the number of bits of the target information may be the number of bits carried by the first sequence. Exemplarily, the preset threshold may be determined by configuration of the network-side device, by agreement, or by negotiation between the first terminal and the network-side device.

The predefined rule is at least one of the following: (1) Determining based on whether the number of bits of the target information is less than or equal to a preset threshold. For example, if the number of bits of the target information is less than or equal to a preset threshold, the first terminal determines that the bits carried by the first sequence are bits of a specific sequence.

For example, if the first terminal is in an RRC idle state or an RRC deactivated state, the first terminal determines that the bits carried by the first sequence are bits of a specific sequence.

For example, if the network-side device configures first indication information for the first terminal, and the first indication information indicates that bits of a specific sequence carried by the first sequence are used to indicate the target information, the first terminal determines that the bits carried by the first sequence are bits of the specific sequence. Of course, in other alternative embodiments, when other conditions are met, the bits of the specific sequence carried by the first sequence are used to indicate the target information, and this application does not make any specific limitation on this.

For example, if the number of bits of the target information is greater than a preset threshold, the first terminal determines that the bits carried by the first sequence are information bits. (2) Determined according to the RRC state that the first terminal is in. For example, if the first terminal is in an RRC connected state, the first terminal determines that the bits carried by the first sequence are information bits. (3) Determined based on the configuration of the network-side device. For example, if the network-side device configures second indication information for the first terminal, and the second indication information indicates that the information bits carried by the first sequence are used to indicate the target information, the first terminal determines that the bits carried by the first sequence are information bits. Of course, in other alternative embodiments, when other conditions are met, the second indication information may indicate that the information bits carried by the first sequence are used to indicate the target information, and this application does not make any specific limitation on this. In some embodiments, the first information bit is determined based on the at least one second sequence when at least one of the following is satisfied: The bits of the specific sequence carried by the first sequence are used to indicate the target information; The first terminal is in an RRC idle state or an RRC deactivated state; The first terminal is configured with third indication information, where the third indication information indicates that the first information bit is determined based on the at least one second sequence; The first sequence does not adopt Manchester encoding. Exemplarily, the first terminal may determine whether to determine the first information bit based on the at least one second sequence according to a predefined rule. The predefined rule is at least one of the following: (1) Determined according to the manner in which the first sequence transmits the target information. For example, if bits of a specific sequence carried by the first sequence are used to indicate the target information, the first terminal determines the first information bits based on the at least one second sequence. (2) Determined according to the RRC state of the first terminal. For example, if the first terminal is in an RRC idle state or an RRC deactivated state, the first terminal determines the first information bit based on the at least one second sequence. (3) Determined based on the configuration of the network-side device. For example, if the network-side device configures third indication information for the first terminal, and the third indication information indicates that the first information bit is determined based on the at least one second sequence, the first terminal determines the first information bit based on the at least one second sequence. (4) Determining based on whether the first sequence uses Manchester coding. For example, if the first sequence does not use Manchester coding, the first terminal determines the first information bit based on the at least one second sequence. Of course, in other alternative embodiments, the first information bit may be determined based on the at least one second sequence under other conditions. For example, when the number of the at least one second sequence is greater than or equal to a preset number, the first information bit is determined based on the at least one second sequence. In some embodiments, the first information bit is determined based on the at least one second sequence and the at least one open symbol when at least one of the following is satisfied: The information bits carried by the first sequence are used to indicate the target information; The first terminal is in an RRC connected state; The first terminal is configured with fourth indication information, where the fourth indication information indicates that the first information bit is determined based on the at least one second sequence and the at least one open symbol; The first sequence adopts Manchester encoding. Exemplarily, the first terminal may determine whether to determine the first information bit based on the at least one second sequence and the at least one open symbol according to a predefined rule. The predefined rule is at least one of the following: (1) Determined based on the manner in which the first sequence transmits the target information. For example, if the information bits carried by the first sequence are used to indicate the target information, the first terminal determines the first information bits based on the at least one second sequence and the at least one open symbol. (2) Determined according to the RRC state of the first terminal. For example, if the first terminal is in an RRC connected state, the first terminal determines the first information bit based on the at least one second sequence and the at least one open symbol. (3) Determined based on the configuration of the network-side device. For example, if the network-side device configures fourth indication information for the first terminal, and the fourth indication information indicates that the first information bit is determined based on the at least one second sequence and the at least one open symbol, the first terminal determines the first information bit based on the at least one second sequence and the at least one open symbol. (4) Determining based on whether the first sequence uses Manchester coding. For example, if the first sequence uses Manchester coding, the first terminal determines the first information bit based on the at least one second sequence and the at least one open symbol. Of course, in other alternative embodiments, the first information bit may be determined based on the at least one second sequence under other conditions. For example, when the number of the at least one second sequence is less than a preset number, the first information bit is determined based on the at least one second sequence and the at least one open symbol. In some embodiments, the number of information bits corresponding to the second sequence in the open symbol is determined based on the following formula: X = log2N; Here, X represents the number of information bits determined based on the at least one second sequence, and N represents the number of candidate sequences corresponding to the open symbol. Exemplarily, assuming that the number of candidate sequences corresponding to the open symbol is N=4, 2 bits of information can be transmitted through one candidate sequence. Exemplarily, assuming that the number of the first information bits is L, the first information bits can be transmitted using M = ceil (L / log2N) open symbols. For example, assuming that the number of candidate sequences corresponding to the open symbols is N = 4, and 2 bits can be transmitted using one candidate sequence, the first information bits can be transmitted using M = ceil (4 / log24) = 2 open symbols. For another example, if 8 bits can be transmitted using one candidate sequence, a specific OOK sequence can be transmitted using M = ceil (8 / log24) = 4 open symbols. In some embodiments, the method 200 may further include: The first terminal determines, based on a type or supported capability of the first terminal, the first sequence or the at least one second sequence as a sequence for determining the target information. Exemplarily, the type of the first terminal includes a receiver type of the first terminal. Exemplarily, when the type of the first terminal is a terminal type that supports demodulating OOK sequences, or when the capabilities supported by the first terminal include the ability to support demodulating OOK sequences, the first terminal determines the first sequence as a sequence for determining the target information; when the type of the first terminal is a terminal type that supports demodulating sequences carried on open symbols of an OOK sequence, or when the capabilities supported by the first terminal include the ability to support demodulating sequences carried on open symbols of an OOK sequence, the first terminal determines the at least one second sequence as a sequence for determining the target information. In some embodiments, the target information includes a cyclic redundancy check (CRC). Exemplarily, the information bits X carried by the first sequence inf includes CRC, and the first information bit does not include CRC. Or, the information bit X carried by the first sequence inf and the first information bits both include CRC. In this embodiment, CRC can improve the accuracy of the target information. For example, when the target information is wake-up information, it can reduce the probability of false wake-up. On the other hand, CRC increases overhead. Whether to send CRC can be based on network configuration or predefined by the standard. The technical solution of this application is described below with reference to specific embodiments. Example 1: In this embodiment, the OOK sequence and the specific OFDM sequence carried by the OOK sequence both transmit target information. FIG10 is an example of transmitting target information through an OOK sequence and a specific OFDM sequence carried on the OOK sequence, respectively, provided by an embodiment of the present application. As shown in FIG10 , it is assumed that the network side device wakes up a group of UEs whose UE subgroup index number is 0 through an LP-WUS. The OOK sequence S sent by the network side device through the OOK symbol of the LP-WUS ook_0 =[0 1 0 1 0 0 1 1] indicates subgroup index number 0. The information bits sent by the network side device through the OFDM sequence carried on the open symbol are X inf =[0 0 0 0]. Assuming that one OFDM symbol carries 4 OOK symbols, then the OOK sequence occupies 2 OFDM symbols, for a total of 8 OOK symbols. The first type of low-power receiver receives the 8 OOK symbols of 2 OFDM symbols to detect the OOK sequence S ook_i The first type of low power receiver determines the awakened UE subgroup based on the detected OOK sequence. The second type of low power receiver receives two ON symbols in one OFDM symbol to detect X inf , each OFDM sequence in the open symbol corresponds to 2 information bits. The second type of low-power receiver determines the information bit X according to the detected OFDM sequence inf , and then based on X inf Determine the awakened UE subgroup. Example 2: In this embodiment, the encoded OOK sequence and the specific OFDM sequence carried on the encoded OOK sequence are both used to transmit target information. FIG11 is an example of transmitting target information through an encoded OOK sequence and a specific OFDM sequence carried on the encoded OOK sequence, respectively, provided by an embodiment of the present application. As shown in Figure 11, it is assumed that the network side device wakes up a group of UEs with a UE subgroup index of 0 through an LP-WUS. The OOK sequence can be combined with Manchester coding to further improve performance. For example, the OOK sequence S sent by the network side device through the OOK symbol of the LP-WUS is ook_0 =[0 1 0 1 0 0 1 1] After Manchester encoding, there are 16 bits in total. Assuming that one OFDM symbol carries 4 OOK symbols, then LP-WUS occupies 4 OFDM symbols. The information bits sent by the network side device through the OFDM sequence on the open symbol are X inf =[0 0 0 0]. The first type low power receiver receives 16 bits of 4 OFDM symbols to detect the OOK sequence S. ook_i The second type of low power receiver receives two open symbols in one OFDM symbol to detect X inf . Example 3: In this embodiment, the encoded information bits carried on the OOK sequence and the OFDM-based sequence are both used to transmit target information. FIG12 is an example provided by an embodiment of the present application of transmitting target information through encoded information bits carried on an OOK sequence and information bits determined based on an OFDM sequence. As shown in FIG12 , it is assumed that the network side device wakes up a group of UEs with a UE subgroup index number of 0 through an LP-WUS, X inf =

[0000] Used to indicate subgroup index 0. The information bits carried by the OOK sequence are information bits X inf After Manchester encoding, one information bit is carried by two OOK symbols. Therefore, the encoded bit is [01010101], that is, the OOK sequence is sent through 8 OOK symbols. inf Assuming that one OFDM symbol carries 4 OOK symbols, then the OOK sequence occupies 2 OFDM symbols. The first information bit corresponding to the OFDM sequence is X inf The information bit X corresponding to the OFDM sequence inf There is no coding. The information bits sent by the network side device through the OFDM sequence carried on the open symbol are X inf =[0 0 0 0]. The first type low power receiver receives 8 OOK symbols of 2 OFDM symbols to obtain information bits X infThe second type of low power receiver receives two open symbols in one OFDM symbol to obtain information bits X inf .
