[0046] The technical solutions in the present disclosure will be described clearly and completely below with reference to the drawings in the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, any other embodiments obtained by a person of ordinary skill in the art without creative effort should fall within the protection scope of the present disclosure.

[0047] It should be noted that in the present disclosure, the words “exemplarily” or “for example” are used to mean by way of example, illustration or description. Any embodiment or design scheme described as “exemplarily” or “for example” in the present disclosure should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the words “exemplarily” or “for example” are intended to present the relevant concept by way of example.

[0048] Hereinafter, the terms "first", "second", and the like are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second", and the like can explicitly or implicitly include one or more of the features.

[0049] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this 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 can mean: only A, only B, and A and B. In addition, "at least one" means one or more, and "multiple" means two or more.

[0050] It can be understood that, without conflict, the functions, steps, etc. shown in the present disclosure can occur in an order different from that shown in the present disclosure, and there can be other functions, steps, etc. between any two adjacent functions, steps, etc. shown in the present disclosure.

[0051] In the field of mobile communication, terminal communication involves issues such as latency, reliability, availability, etc., in addition, the energy efficiency of the terminal also affects the actual experience of the user. At present, according to the use time of an individual, the terminal needs to be charged every week or every day, usually, the device consumes tens of milliwatts of power in the radio resource control (RRC) idle / inactive state, and hundreds of milliwatts of power in the RRC connected state, improving the terminal battery endurance time can effectively improve the user's use experience.

[0052] As described above, the power consumption is affected by the state of the terminal, in the related art, the terminal can be periodically woken up by configuring the length of the wake-up cycle of the terminal, for example, the paging cycle. At present, the wake-up cycle of the terminal is usually configured by extending the extended discontinuous reception (eDRX) cycle, however, the communication latency of this scheme is high, which affects the normal use of the user.

[0053] A low power wake up (LP-WU) mechanism is a low power communication scheme for Internet of Things (IoT) devices, which can receive a low power wake up signal (LP-WUS) through a separate receiver, thereby triggering data transmission and data reception of a main radio. When the IoT device does not detect the low power wake up signal, the main radio is in a deep sleep state, thereby further reducing the power consumption of the terminal. There is currently no clear transmission scheme for the low power wake up related signal of the terminal in mobile communication.

[0054] In view of this, in the technical solutions provided in the present disclosure, the first node can send a first signal, which includes at least one first structure in the time domain, and the first structure includes at least one of at least one on-off keying (OOK) symbol and at least one orthogonal frequency division multiplexing (OFDM) symbol. Since the OOK symbol and the OFDM symbol can carry the low power wake up signal, the present disclosure proposes a communication scheme for signal transmission through the OOK symbol and / or the OFDM symbol in the time domain, for communication interaction of the terminal in the low power wake up process.

[0055] The network architecture of the mobile communication network (including but not limited to 3G, 4G, 5G and future mobile communication networks) in the embodiments of the present disclosure can at least include a first communication node and a second communication node. It should be understood that in the present example, the first communication node can be a network side device (including but not limited to a base station) in the downlink, and the second communication node can be a terminal side device (including but not limited to a terminal). Of course, in the uplink, the first communication node can also be a terminal side device, and the second communication node can also be a network side device. In device-to-device communication, the first communication node and the second communication node can both be base stations or terminals. The first communication node and the second communication node can be referred to as the first node and the second node, respectively.

[0056] Exemplarily, taking the first communication node as a base station and the second communication node as a terminal as an example, as shown in FIG. 1, a communication system provided by the embodiments of the present disclosure includes a base station 101 and a terminal 102. The base station 101 and the terminal 102 can be one or more, and the number is not limited.

[0057] The base station 101 is a device with wireless transceiving function or a chip or chip system that can be arranged in the device on the access network side of the above communication system. The base station 101 includes but is not limited to: an access point (AP) in a WiFi system, such as a home gateway, a router, a server, a switch, a bridge, and the like, an evolved NodeB (eNB), a radio network controller (RNC), a NodeB (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (for example, a home evolved NodeB or a home NodeB, HNB), a baseband unit (BBU), a wireless relay node, a wireless backhaul node, a transmission and reception point (TRP or TP), and the like, and can also be a 5G base station, such as a gNB in a new radio (NR) system or a transmission point (TRP or TP), one or a group of (including multiple antenna panels) antenna panels of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU), a distributed unit (DU), a road side unit (RSU) with base station function, or a 5G access network (NG radio access network, NG-Ran) device, and the like. The base station 101 also includes base stations in different networking modes, such as a master evolved NodeB (MeNB), a secondary eNB (SeNB or SgNB). The base station 101 also includes different types, such as ground base stations, air base stations, and satellite base stations, and the like.

[0058] The terminal 102 is a device with wireless communication function, which can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted. It can also be deployed on water (such as ships, etc.). It can also be deployed in the air (such as airplanes, balloons and satellites, etc.). The terminal 102 is also called user equipment (UE), mobile station (MS), mobile terminal (MT) and terminal device, which is a device that provides voice and / or data connectivity to users. For example, the terminal 102 includes handheld devices with wireless connection function, vehicle-mounted devices, etc. At present, the terminal 102 can be: mobile phone, tablet computer, notebook computer, palm computer, mobile internet device (MID), wearable device (such as smart watch, smart bracelet, pedometer, etc.), vehicle-mounted device (such as car, bicycle, electric vehicle, airplane, ship, train, high-speed rail, etc.), virtual reality (VR) device, augmented reality (AR) device, wireless terminal in industrial control, smart home device (such as refrigerator, television, air conditioner, electric meter, etc.), smart robot, workshop equipment, wireless terminal in self driving, wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, or wireless terminal in smart home, flight equipment (such as smart robot, hot air balloon, unmanned aerial vehicle, airplane), etc. In a scenario where the present disclosure is applied, the terminal is a terminal that usually works on the ground, such as a vehicle-mounted device. In the present disclosure, in order to facilitate description, a chip deployed in the above-mentioned devices, such as system on a chip (SOC), baseband chip, etc., or other chips with communication function can also be referred to as a terminal.

[0059] The base station 101 can wake up the terminal 102 through a low-power wake-up mechanism.

[0060] Exemplarily, the low power wake up mechanism involves low power wake up signal (LP-WUS), low power synchronization signal (LP-SS), low power preamble (LP-Preamble).

[0061] The LP-WUS is used to carry low power wake up information.

[0062] The role of the LP-SS includes at least one of the following: performing radio resource management (RRM) measurement by detecting the LP-SS, performing downlink synchronization by detecting the LP-SS, and performing frequency offset correction by detecting the LP-SS.

[0063] The role of the LP-Preamble includes at least one of the following: performing RRM measurement by detecting the LP-Preamble, performing downlink synchronization by detecting the LP-Preamble, and performing frequency offset correction by detecting the LP-Preamble.

[0064] In some embodiments, the transmission of the LP-Preamble is located before the LP-WUS, and the terminal 102 performs downlink synchronization and / or frequency offset correction by detecting the LP-Preamble, thereby improving the detection performance of the terminal 102 in detecting the LP-WUS.

[0065] The waveform of the above-mentioned signals (LP-WUS / LP-SS / LP-Preamble) can be generated by an OOK modulation mode, which is referred to as OOK based LP-WUS / LP-SS / LP-Preamble. In addition, in the present disclosure, the above-mentioned signals can be carried by multiple subcarriers, that is, when the number of subcarriers occupied by the OOK based LP-WUS / LP-SS / LP-Preamble in the frequency spectrum is greater than 1, it is referred to as multiple subcarrier (MC)-OOK based LP-WUS / LP-SS / LP-Preamble.

[0066] In some embodiments, the present disclosure can generate MC-OOK based LP-WUS / LP-SS / LP-Preamble by the following mode 1 or mode 2.

[0067] Mode 1: As shown in FIG. 2, the data information transmitted on M OOK symbols is S M , which includes M elements, that is, S M includes M elements, that is, S MThe length is M, denoted as S. M =[s0,s1,s2,s3...,s M-1 The data information can include source information, verification information, and padding information, etc. This data information S M It can also be obtained after processing the data information to be transmitted. For example, data processing includes at least one of the following: segmentation, repetition, bit-level repetition, source coding, channel coding, modulation, interleaving, adding padding bits, adding cyclic redundancy check (CRC) bits, and rate matching. Data information S M It can be referred to as coded bit information, coded sequence information, or code word information.

[0068] Step 1: Transfer data information S M Convert to data information Q K , where Q K The length is K, where K is greater than or equal to 1.

[0069] For example, data information Q K It can satisfy either Formula 1 or Formula 2:

[0070] A0 represents Q K The first group of elements The number of elements, A1 represents Q. K The second group of elements The number of elements, and so on. A0 + A1 + ... A i +…+A M-1 =K. Parameter data in Formula 2 The value can be configured, 0≤i≤M-1.

[0071] S M element s in i Corresponding to Q K elements in or Q K A in i element Some elements in the array can be configured as zero elements or predefined values.

[0072] Understandably, the Q shown above... K The generation formula is only an example; others will use S. M Convert to data information Q of length KK The generating formula is not listed here.

[0073] Step 2: Perform K-point discrete Fourier transform (DFT) / fast Fourier transform (FFT) operation on the data information Q K to obtain data information D K = [d0, d1, d2, d3,..., d K-1 ].

[0074] In some embodiments, at least one of the following operations can also be performed on the data information D K :

[0075] Perform an upward circular shift operation on D K with a size of or or K / 2.

[0076] Perform a downward circular shift operation on D K with a size of or or K / 2.

[0077] Perform a left circular shift operation on D K with a size of or or K / 2.

[0078] Perform a right circular shift operation on D K with a size of or or K / 2.

[0080] Exemplarily, the above operations can be performed by an FFTSHIFT function, which is a function for moving the zero frequency component of the Fourier transform to the center of the spectrum. For a vector X, FFTSHIFT(X) exchanges the left and right halves of X or exchanges the upper and lower halves of X. For a matrix X, FFTSHIFT(X) exchanges the first and third quadrants, and the second and fourth quadrants.

[0081] Step 3: Fill the data information D K into K subcarriers on the frequency domain, and perform inverse Fourier transform to obtain time domain data T N .

[0082] In some embodiments, the frequency domain bandwidth of the system as a whole comprises N subcarriers, and the data information D K corresponding to the K subcarriers, other subcarriers can be filled with other data to be transmitted. Then, an inverse discrete Fourier transform (IDFT) / inverse fast Fourier transform (IFFT) operation is performed on the filled data on the N subcarriers to obtain time domain data T N = [t0, t1, t2, t3,..., t N-1 ]. N is greater than or equal to 1. T N = [t0, t1, t2, t3,..., t N-1 ] is the sampling point data of the M OOK symbols.

[0083] is the sampling point data of the first OOK symbol in the M OOK symbols, is the sampling point data of the second OOK time domain symbol in the M OOK time domain symbols, and so on, is the sampling point data of the Mth OOK time domain symbol in the M OOK time domain symbols.

[0084] In some embodiments, before performing the inverse Fourier transform, at least one of the following operations can also be performed on the data filled on the N subcarriers:

[0088] performing a right cyclic shift operation on the data, and the size of the cyclic shift is or or N / 2.

[0089] is a ceiling operator, is a floor operator.

[0090] Step 4: Based on the time-domain data T from N sampling points N =[t0,t1,t2,t3,...,t N-1 Add a cyclic prefix (CP), generate the first signal, and send the first signal.

[0091] The added cyclic prefix can be time-domain data T with N sampling points. N N at the tail cp The information from each sampling point, the generated first signal carries (N+N) cp The time-domain data consists of 10 sampling points. The first signal can be a wake-up signal, a synchronization signal, or a preamble signal, such as MC-OOK based LP-WUS / LP-SS / LP-Preamble.

[0092] Furthermore, in step 3 above, when the number of frequency domain subcarriers allocated for MC-OOK based LP-WUS / LP-SS / LP-Preamble is not K, for example, if the allocated frequency domain subcarriers are K1, K1 is not equal to K. As shown in Figure 3, step 3 above can be implemented through the following process:

[0093] (1) Data information D K =[d0,d1,d2,d3,…,d K-1 Process D K Convert to E K1 .

[0094] E K1 =[e0,e1,e2,e3,...,e K1-1 For example, conversion operations can include repeating, truncating, and drilling.

[0095] In some embodiments, E can also be used. K1 Perform at least one of the following operations:

[0096] For E K1 Perform an upward circular shift operation, the size of which is or Or K1 / 2.

[0097] For E K1 Perform a downward circular shift operation, the size of which is or Or K1 / 2.

[0098] For E K1 Perform a left circular shift operation, the size of which is or Or K1 / 2.

[0099] For E K1 Perform a right circular shift operation, the size of which is or Or K1 / 2.

[0100] This is the round-up operator. This is the floor operator.

[0101] (2) Transfer data information E K1 The data is filled onto K1 subcarriers in the frequency domain and then subjected to an inverse Fourier transform to obtain the time-domain data T. N .

[0102] Subsequent operations can be referred to steps 3-4 above, and will not be repeated here.

[0103] Method 2: As shown in Figure 4, the data information transmitted on M OOK symbols is S M S M It contains M elements, namely S M The length is M, denoted as S. M =[s0,s1,s2,s3...,s M-1 ].

[0104] Step 1: Transfer data information S M Convert to data information in, The length is Greater than or equal to 1.

[0105] For example, data information It can satisfy either formula 3 or formula 4:

[0106] A0 indicates The first group of elements The number of elements, A1 represents The second group of elements The number of elements, and so on. Parameter data in Formula 4 The value can be configured, 0≤i≤M-1.

[0107] Step 2: Process the data information through the first processing module. The data information D is obtained through processing. K =[d0,d1,d2,d3,...,d K-1 ] T .

[0108] For example, data information D KThe following equation 5 can be satisfied:

[0110] F is a matrix composed of K column elements in the IDFT Matrix, and F is a matrix with N rows and K columns. Exemplarily, the IDFT Matrix can be represented by the following equation 6 or equation 7:

[0111] The K column elements in the IDFT Matrix composed of F can be at least filled by N column elements in the IDFT Matrix, and the data information D K is determined by the K subcarrier positions or subcarrier indexes filled on the frequency domain.

[0112] In some embodiments, at least one of the following operations can be performed on D K :

[0113] The up-cyclic shift operation is performed on D K , and the size of the cyclic shift is , or , or K / 2.

[0114] The down-cyclic shift operation is performed on D K , and the size of the cyclic shift is , or , or K / 2.

[0115] The left-cyclic shift operation is performed on D K , and the size of the cyclic shift is , or , or K / 2.

[0116] The right-cyclic shift operation is performed on D K , and the size of the cyclic shift is , or , or K / 2.

[0117] is the ceiling operator, is the floor operator.

[0118] Step 3: The data information D KThe K subcarriers in the frequency domain are filled, and inverse Fourier transform is performed to obtain time domain data T N .

[0119] In some embodiments, the frequency domain bandwidth of the system as a whole includes N subcarriers, and the data information D K corresponding to the K subcarriers, and other subcarriers can be filled with other data to be transmitted. Then, N-point IDFT / IFFT operation is performed on the filled data on the N subcarriers to obtain N sampling point time domain data T N = [t0, t1, t2, t3, …, t N-1 ]. N is greater than or equal to 1. T N = [t0, t1, t2, t3, …, t N-1 ] is the sampling point data of the M OOK symbols.

[0120] is the sampling point data of the first OOK symbol in the M OOK symbols, is the sampling point data of the second OOK time domain symbol in the M OOK time domain symbols, and so on, is the sampling point data of the Mth OOK time domain symbol in the M OOK time domain symbols.

[0121] Step 4: based on the N sampling point time domain data T N = [t0, t1, t2, t3, …, t N-1 ], a CP is added to generate a first signal, and the first signal is transmitted.

[0122] The added cyclic prefix can be the tail N N sampling point information of the N sampling point time domain data T cp , and the generated first signal carries (N+N cp ) sampling point time domain data. The first signal can be a wake-up signal or a synchronization signal or a preamble signal, for example, MC-OOK based LP-WUS / LP-SS / LP-Preamble.

[0123] In addition, in the above step 3, when the number of frequency domain subcarriers allocated for the MC-OOK based LP-WUS / LP-SS / LP-Preamble is not K, for example, the number of allocated frequency domain subcarriers is K1, and K1 is not equal to K. As shown in FIG. 5, the above step 3 can be implemented by the following process:

[0124] (1) The data information D K = [d0, d1, d2, d3, …, d K-1 ] is processed by the second processing module, and D KConvert to E K1 .

[0126] (2) Transfer data information E K1 The data is filled onto K1 subcarriers in the frequency domain and then subjected to an inverse Fourier transform to obtain the time-domain data T. N .

[0156] It should be noted that the embodiments of the present disclosure can be mutually borrowed or referred to each other, for example, the same or similar steps, method embodiments, system embodiments and device embodiments can be mutually referred to, without limitation.

[0157] FIG. 6 is a flowchart of a signal transmission method provided by an embodiment of the present disclosure. As shown in FIG. 6, the method comprises the following steps:

[0158] Step 601, a first signal is sent.

[0159] The first signal comprises at least one first structure in the time domain.

[0160] The first structure comprises at least one of the following:

[0161] at least one on-off keying (OOK) symbol;

[0162] at least one orthogonal frequency division multiplexing (OFDM) symbol.

[0163] Exemplarily, the first signal can be a wake-up signal or a synchronization signal or a preamble signal, for example, LP-WUS, LP-SS, LP-Preamble.

[0164] In some embodiments, the first structure can include M OOK symbols, wherein the time domain positions of the M OOK symbols are the same as the time domain positions of 1 OFDM symbol, or the M OOK symbols are contained in 1 OFDM symbol. That is, multiple OOK symbols can be included in an OFDM symbol.

[0165] The M OOK symbols correspond to data information S M Correspondingly, S M includes M elements, that is, S M has a length of M and is denoted as S M = [s0, s1, s2, s3,..., s M-1 ]. The data information can be source information, check information, padding information, etc. The data information S M may also be obtained after data processing based on the data information to be transmitted. For example, the data processing includes at least one of the following: blocking, repetition, bit-level repetition, source coding, channel coding, modulation, interleaving, adding padding bits, adding CRC bits, rate matching. The data information S M may be referred to as coded bit information, coded sequence information, or code word information.

[0166] In the technical solutions provided in the present disclosure, the first node can send a first signal, and the first signal includes at least one first structure in the time domain, and the first structure includes at least one of the following: at least one on-off keying (OOK) symbol and at least one orthogonal frequency division multiplexing (OFDM) symbol. Since the OOK symbol and the OFDM symbol can carry a low-power wake-up signal, the present disclosure proposes a communication scheme for signal transmission through OOK symbols and / or OFDM symbols in the time domain, so as to realize communication interaction of a terminal in a low-power wake-up process.

[0167] In some embodiments, the first structure includes:

[0168] at least one first data information;

[0169] at least one second data information.

[0170] The second data information is at least one of the following:

[0171] preconfigured or predefined or pre-stored data information;

[0172] part of the data information in the first data information.

[0173] Exemplarily, the preconfigured or predefined or pre-stored data information can be data information with a value of 0. The first data information is to-be-transmitted information, for example, the sampling point data information of one OOK symbol in the sampling point data of the M OOK symbols in the time domain. N = [t0, t1, t2, t3, …, t N-1 ]. N is greater than or equal to 1. T N = [t0, t1, t2, t3, …, t N-1 ] is the sampling point data of the M OOK symbols.

[0174] Part of the first data information can be data information with a length of N2 from the first information in the first data information.

[0175] Alternatively, part of the first data information can be data information with a length of N2 in the first data information and ending at the last information in the first data information.

[0176] Alternatively, part of the first data information can be cyclic prefix information with a length of N2 in the first data information.

[0177] Alternatively, part of the first data information can be cyclic postfix information with a length of N2 in the first data information.

[0178] It should be noted that the cyclic prefix operation is to move the tail of a signal to the head of the signal. The cyclic postfix operation is to move the head of a signal to the tail of the signal. The above description only illustrates the structural characteristics of the second data information by taking the signal through the cyclic prefix operation and taking the signal through the cyclic postfix operation. The second data information in the present disclosure can also be generated in other ways, and the actual operation performed in the present disclosure is not limited.

[0179] Based on the above technical solutions, the first structure in the present disclosure can include first data information to be transmitted and second data information, which can be determined based on the first data information through preconfiguration, predefinition, pre-storage or the like. During signal transmission, the signal may be affected by various factors, resulting in a deviation of the time at which the signal reaches the receiving end relative to the expected or reference time, that is, there is a time offset problem, which further increases the bit error rate and affects the normal communication of the device. Therefore, the present disclosure can introduce the second data information into the first signal, so that the receiving end can correct the time offset based on the second data information, thereby suppressing the time offset problem of signal transmission to ensure the normal communication of the device.

[0180] In some embodiments, the configuration information of the first data information and / or the second data information is determined by at least one of the following:

[0181] by the number of OOK symbols included in one OFDM symbol;

[0182] by the indication information;

[0183] by the preconfigured information.

[0184] Exemplarily, the first node can indicate the configuration information of the first data information and / or the second data information in the first signal by sending the indication information to the second node, so that the second node can correctly demodulate the first signal after receiving the first signal.

[0185] In some embodiments, the above scheme includes at least one of the following:

[0186] The configuration information of the first data information includes at least one of the following:

[0187] the number of the first data information in one first structure;

[0188] the position information of the first data information in one first structure;

[0189] the length information of the first data information in one first structure.

[0190] The configuration information of the second data information includes at least one of the following:

[0191] the number of the second data information in one first structure;

[0192] the position information of the second data information in one first structure;

[0193] the length information of the second data information in one first structure.

[0194] Exemplarily, the number of the first data information in one first structure can be the number M of elements in the data information S to be transmitted. M The number of the second data information in one first structure can be determined based on the number of the first data information in one first structure.

[0195] When a plurality of first data information is included in one first structure, the lengths of the plurality of first data information can be the same, different, or individually configured. When a plurality of second data information is included in one first structure, the lengths of the plurality of second data information can be the same, different, or individually configured.

[0196] For example, the configuration information is determined by the number of OOK symbols included in one OFDM symbol, the number of first data information in one first structure is M, and the number of first data information in one first structure and the number of second data information in one first structure can satisfy the following table 1 or table 2:

[0197] Table 1 Number relationship table of first data information and second data information

[0198] Table 2 Number relationship table of first data information and second data information

[0199] That is, the number N of second data information Data2 = the value of M + 1, or the number N of second data information Data2 = the value of M.

[0200] For example, the configuration information is determined by the indication information, and the indication information, the number of first data information in one first structure, and the number of second data information in one first structure can satisfy the following table 3:

[0201] Table 3 Indication information mapping table

[0202] The second node can determine the number of first data information and the number of second data information based on the received indication information through the above indication information mapping table.

[0203] Based on the above technical solution, the second node can determine the related configuration parameters of each data information in the first structure in the time domain of the first signal based on the configuration information, so as to facilitate subsequent correct parsing of the data carried in the first signal after receiving the first signal, triggering corresponding synchronization, wake-up and other operations.

[0204] In some embodiments, at least one second data information includes second data information of a first length and / or second data information of a second length.

[0205] The second length is greater than the first length. For example, when the length of the second data information of the first length is X, the length of the second data information of the second length is 2*X or 2*X+ / -Y.

[0206] Y can be configured according to actual conditions, for example, when the length and number of first data information and second data information of lengths X and 2X do not fully occupy the resources of the first structure or exceed the limit of the resources of the first structure, the value of Y can be adjusted to finally meet the resource requirements of the first structure.

[0207] In some embodiments, one second data information of the second length is included between adjacent first data information, or two second data information of the first length are included between adjacent first data information.

[0208] In some embodiments, one first data information of the first length is included before the first first data information in the first structure, and / or one first data information of the first length is included after the last first data information in the first structure.

[0209] For example, the number of first data information is 2, the number of second data information is 3, and the distribution of data information in the first structure is shown in FIG. 7, one first data information of the first length is included before the first first data information and after the last first data information. One second data information of the second length is included between two first data information. The second data information can carry all-zero information.

[0210] For example, the number of first data information is 2, the number of second data information is 2, and the distribution of data information in the first structure is shown in FIG. 8, one first data information of the first length is included after the last first data information. One second data information of the second length is included between two first data information. The second data information can carry all-zero information.

[0211] For example, the number of first data information is 4, the number of second data information is 5, and the distribution of data information in the first structure is shown in FIG. 9, one first data information of the first length is included before the first first data information and after the last first data information. One second data information of the second length is included between two adjacent first data information, and a total of three second data information of the second length is included. The second data information can carry all-zero information.

[0212] For example, the number of first data information is 4, the number of second data information is 4, and the distribution of data information in the first structure is shown in FIG. 10, one first data information of the first length is included after the last first data information. One second data information of the second length is included between two adjacent first data information, and a total of three second data information of the second length is included. The second data information can carry all-zero information.

[0213] Based on the above technical solutions, after receiving the first signal, the second node can correct the time offset based on the second data information distributed in the first signal, thereby ensuring the correct parsing of the first data information in the first signal.

[0214] In some embodiments, the first structure is generated at least by a second structure, and the second structure includes:

[0215] at least one third data information;

[0216] at least one fourth data information.

[0217] The fourth data information is at least one of:

[0218] pre-configured or pre-defined or pre-stored data information;

[0220] Exemplarily, the second structure can include the data information S M converted data information Q K . The data information Q K has a length of K, K is greater than or equal to 1. Exemplarily, the pre-configured or pre-defined or pre-stored data information can be data information with a value of 0. The third data information can be generated based on the data information S M , i.e., the third data information has a corresponding relationship with the elements in the data information S M . The first data information in the first structure can be generated through the third data information in the second structure, and the second data information in the first structure can be generated through the fourth data information in the second structure.

[0221] Exemplarily, the data information Q K satisfies the following formula 16:

[0222] A0+A1+…+A M-1 +B0+B1+…+B M-1 = K, in the above formula, the values of the data may be configured. 0≤i≤M-1. For example, all can be configured as 1. i.e., the fourth data information. i.e., the third data information. The pre-configured or pre-defined or pre-stored data information can be zero, i.e. 0≤b i ≤B i -1.

[0223] In some embodiments, part of the third data information can be data information with a length of N2 in the third data information starting from the first information.

[0224] Alternatively, part of the third data information can be data information with a length of N2 in the third data information and ending at the last information of the third data information.

[0225] Alternatively, part of the third data information can be cyclic prefix information with a length of N2 in the third data information.

[0226] Alternatively, part of the data information in the third data information can be cyclic postfix information with a length of N2.

[0227] It should be noted that the cyclic prefix operation is to move the tail signal of a signal to the head of the signal. The cyclic postfix operation is to move the head signal of a signal to the tail of the signal. The above description only describes the structural characteristics of the fourth data information by taking the signal through the cyclic prefix operation and taking the signal through the cyclic postfix operation. The fourth data information in the present disclosure can also be generated in other ways, and the actual operation performed by the present disclosure is not limited.

[0228] For example, in combination with the above formula 16, the fourth data information may be B i elements in the last B i elements or the first B i elements in
