Signal sending method, signal receiving method, communication device and storage medium

[0001] This disclosure claims priority to Chinese patent application No. 202311018885.3, filed on August 11, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of communication network technology, and in particular to a signal sending method, a signal receiving method, a communication device, and a storage medium. Background Art

[0003] For fifth-generation mobile communication technology (5G) systems, in addition to latency, reliability, and availability, energy efficiency of terminal devices or user equipment (UE) is also crucial. Currently, 5G devices may need to be charged weekly or daily depending on individual usage time. Typically, 5G devices consume 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. Therefore, extending battery life is a necessary condition for improving energy efficiency and improving user experience.

[0004] Because power consumption depends on the length of the configured wake-up cycle, such as the paging cycle, a low power wake-up (LP-WUS) mechanism is introduced to meet battery life requirements. This mechanism uses a separate receiver to receive LP-WUS signals, which are used to wake up the main radio equipment for data transmission and reception. When the UE does not detect the LP-WUS signal, the main receiver enters a deep sleep state, further reducing terminal power consumption.

[0034] The following will clearly and completely describe the technical solutions of this disclosure in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of this disclosure, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0035] It should be noted that in this disclosure, expressions such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described in this disclosure as "exemplarily" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of expressions such as "exemplarily" or "for example" is intended to present the relevant concepts in a detailed manner.

[0036] In the following, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of the features.

[0037] In the description of this disclosure, unless otherwise specified, " / " means "or." For example, A / B can mean A or B. "And / or" herein is simply a description of an association relationship between associated objects, indicating that three possible relationships exist. For example, A and / or B can mean: only A, only B, and A and B. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0038] As mentioned in the background technology, in order to meet the requirements of battery life, an ultra-low power wake-up LP-WUS mechanism is introduced. That is, the user uses a separate receiver to receive the LP-WUS signal, and uses the LP-WUS signal to wake up the main radio equipment for data transmission and reception; when the UE does not detect the LP-WUS signal, the main receiver is in a deep sleep state, which further reduces the power consumption of the terminal.

[0039] However, the use of an ultra-low-power LP-WUS wake-up mechanism affects LP-WUS signal detection performance. Furthermore, frequency offset significantly impacts LP-WUS signal detection. Therefore, improving LP-WUS signal detection performance while minimizing the impact of frequency offset on detection performance during LP-WUS signal reception is an urgent issue.

[0040] To address the above technical issues, embodiments of the present disclosure provide a signal transmission method and a signal reception method. The concept is as follows: a signal transmission end transmits a first signal, and the first signal carries first data information; the first signal can occupy at least one time domain symbol; accordingly, a signal reception end receives the first signal and obtains the first data information carried in the first signal. It is understood that the first signal carries the first data information, and the first data information can be carried on at least one time domain symbol. In this way, when the signal reception end receives the detection signal, it can reduce the impact of frequency domain offset on detection performance, thereby improving signal detection performance.

[0041] The technical solutions provided in the embodiments of the present disclosure can be applied to various mobile communication networks, for example, 5G New Radio (NR) mobile communication networks, future mobile communication networks, or multiple communication convergence systems, etc., and the embodiments of the present disclosure are not limited to this.

[0042] The network architecture of the mobile communication network (including but not limited to 3G, 4G, 5G and future mobile communication networks) in the embodiment of the present disclosure may include at least a first communication node and a second communication node. It should be understood that in this example, the first communication node in the downlink may be a network side device (for example, including but not limited to a base station), and the second communication node may be a terminal side device (for example, including but not limited to a terminal). Of course, in the uplink, the first communication node may also be a terminal side device, and the second communication node may also be a network side device. In the device-to-device communication between the two communication nodes, the first communication node and the second communication node may both be a base station or a terminal. The first communication node and the second communication node may be referred to as the first node and the second node, respectively.

[0043] For example, taking the first communication node as a base station and the second communication node as a terminal, Figure 1 shows a schematic diagram of a network architecture of a mobile communication network provided by an embodiment of the present disclosure. As shown in Figure 1 , the mobile communication network includes a base station 110 and a terminal 120.

For example, a base station provides a service coverage area (also referred to as a cell). Terminals within this area can communicate with the base station via wireless signals to receive the wireless access services provided by the base station.

The base station may include various network-side devices such as various macro base stations, micro base stations, home base stations, wireless remote devices, reconfigurable intelligent surfaces (RIS), routers, and wireless fidelity (WIFI) devices.

[0046] In some embodiments, the terminal 120 may be a device with wireless transceiver capabilities, which may be deployed on land (including indoors or outdoors, handheld, wearable, or vehicle-mounted); may also be deployed on water (such as ships); and may also be deployed in the air (such as airplanes, balloons, and satellites).

[0047] It should be noted that Figure 1 is only an exemplary framework diagram. The number of devices included in Figure 1 and the names of each device are not restricted. In addition to the devices shown in Figure 1, the communication system may also include other devices (such as core network devices).

[0048] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0049] Figure 2 shows a data processing flow chart for a transmitter and receiver. As shown in Figure 2, the transmitter performs source coding, channel coding, modulation, and resource mapping on the signal source (i.e., the data to be transmitted) to generate a signal that is then sent to the receiver. Upon receiving this signal, the receiver performs resource demapping, demodulation, channel decoding, and source decoding on it to obtain the destination (i.e., the restored source).

[0050] The signal transmission method and signal reception method provided by the embodiments of the present disclosure are described in detail below. For example, the signal transmission method and signal reception method provided by the embodiments of the present disclosure can be applied to the mobile communication network shown in FIG1 .

[0051] As shown in FIG3 , the signal sending method and the signal receiving method provided by the embodiment of the present disclosure may include the following steps.

[0052] S101: A first communication node sends a first signal, and a second communication node receives the first signal accordingly.

[0053] For example, the first signal may be an LP WUS signal. It is understood that the use of the ultra-low power consumption wake-up mechanism LP WUS signal can reduce energy consumption.

[0054] The first signal occupies at least one time domain symbol in the time domain.

[0055] Exemplarily, the time domain symbol may include any one of the following: an on-off keying (OOK) symbol, a multi-carrier OOK (MC-OOK) symbol, a frequency-shift keying (FSK) symbol, a multi-carrier FSK (MC-FSK) symbol, or an orthogonal frequency division multiplexing (OFDM) symbol. In some embodiments, the time domain symbol is an OFDM symbol.

[0056] In some embodiments, the first signal carries first data information.

[0057] Exemplarily, the first data information may include at least one of the following: information source information, cyclic redundancy check (CRC) bits, and padding bits.

[0058] The padding bits are used to fill in the missing bits when the number of the first data information is less than the default number or the configured number. For example, assuming that the first data information The number of Bits, the default number is L B ,like The first data information Also included The padding bits of the bit can be filled with some default value.

[0059] In some embodiments, the first signal carries first data information, including: the first signal carries at least one second data information generated by the first data information.

[0060] The second data information includes at least one second sub-data information; each second sub-data information is carried in at least one time domain symbol for transmission.

[0061] Exemplarily, the time-frequency resources corresponding to each second sub-data information occupy the same frequency domain resource position in the frequency domain; alternatively, the frequency domain resources occupied by each second sub-data information in the frequency domain are independently configured; alternatively, the frequency domain resource position occupied by each second sub-data information in the frequency domain is indicated by information. Exemplarily, the base station may indicate the detailed frequency domain resource position through information; alternatively, the detailed frequency domain resource position may be determined according to a default configuration; alternatively, the detailed frequency domain resource position may be determined according to a frequency hopping rule and in combination with information sent by the base station.

[0062] In some embodiments, the second data information is generated in the following manner.

[0063] Method 1: Generate the second data information through the following steps a1 to a3.

[0064] a1. Perform a first operation on the first data information to obtain third data information.

[0065] For example, it is assumed that the first data information can be expressed as: Then the first operation is performed on the first data information to obtain the third data information: The length of the third data information is L C bit.

[0066] Exemplarily, the first operation may include at least one of the following: bit-level repetition, encoding, modulation, interleaving, adding padding bits, and adding CRC bits.

[0067] Performing a bit-level repetition operation on the first data information refers to repeating each bit information in the first data information.

[0068] For example, assuming that the first data information It can be expressed as: Length L B bits. Then the first data information The bit-level repetition operation includes: b in i Repeat R0 times to generate data information with a length of R0 It can be expressed as:

[0069] Exemplarily, the above-mentioned coding may include at least one of the following: Manchester coding, Miller coding, pulse interval encoding (PIE), bi-phase space coding (or FM0 coding), Reed-Muller (RM) coding and polar coding, etc.

[0070] Interleaving is used to spread out successive bits of information and send them in a non-sequential manner.

[0071] Adding padding bits refers to adding padding bits to the first data information.

[0072] Adding CRC bits refers to adding CRC bits to the first data information. Exemplarily, adding CRC bits can be implemented in the following manner.

[0073] When the source information is 2 bits, the CRC is selected from [2, 4, 6, 8] bits.

[0074] When the source information is 4 bits, the CRC is selected from [4, 6, 8, 10] bits.

[0075] When the source information is 6 bits, the CRC is selected from [4, 6, 8, 10, 12] bits.

[0076] When the source information is 8 bits, the CRC is selected from [4, 6, 8, 10, 12, 14, 16] bits.

[0077] When the source information is 10 bits, the CRC is selected from [6, 8, 10, 12, 14, 16] bits.

[0078] When the source information is 12 bits, the CRC is selected from [6, 8, 10, 12, 14, 16] bits.

[0079] When the source information is 14 bits, the CRC is selected from [6, 8, 10, 12, 14, 16] bits.

[0080] When the source information is 16 bits, the CRC is selected from [8, 10, 12, 14, 16, 18, 20, 22, 24] bits.

[0081] When the source information is 18 bits, the CRC is selected from [8, 10, 12, 14, 16, 18, 20, 22, 24] bits.

[0082] When the source information is 20 bits, the CRC is selected from [8, 10, 12, 14, 16, 18, 20, 22, 24] bits.

[0083] When the source information is 22 bits, the CRC is selected from [8, 10, 12, 14, 16, 18, 20, 22, 24] bits.

[0084] When the source information is 24 bits, the CRC is selected from [8, 10, 12, 14, 16, 18, 20, 22, 24] bits.

[0085] When the source information is 36 bits, the CRC is selected from [8, 10, 12, 14, 16, 18, 20, 22, 24, 32, 36, 48] bits.

[0086] When the source information is 48 bits, the CRC is selected from [8, 10, 12, 14, 16, 18, 20, 22, 24, 32, 36, 48] bits.

[0087] a2. Divide the third data information into at least one third sub-data information.

[0088] The third sub-data information includes a plurality of data elements read consecutively in the third data information.

[0089] It is understood that one third sub-data message can be used as a data block (Block), including all or part of the data information in the third data message. For example, when the third data message is divided into multiple third sub-data messages, the content of each third sub-data message is different, and the collection of multiple third sub-data messages constitutes the complete third data message; when the third data message is divided into one third sub-data message, the third sub-data message includes all the data information of the third data message.

[0090] For example, the third sub-data information with index i in the at least one third sub-data information can be represented as Length is bits. i is an integer, and 0≤i≤I-1, and I is an integer greater than or equal to 1. It can be seen that when the value of i is 0, the number of third sub-data information is 1, that is, the third sub-data information is the third data information.

[0091] In some embodiments, the third sub-data information can be carried by a sequence. For example, assuming that the third sub-data information The length of is 4, then 4 2 = 16 sequences are used to carry different values ​​of the third sub-data information.

[0092] a3. For each third sub-data information, repeat the third sub-data information R1 times to obtain the second data information, where R1 is a positive integer.

[0093] It can be understood that the third sub-data information is repeated once, that is, the third sub-data information is sent once in the first signal.

[0094] In the first approach, the third sub-data information is the second sub-data information, that is, one piece of third sub-data information can be carried in at least one time domain symbol for transmission.

[0095] For example, the second data information formed by repeating the third sub-data information R1 times can be It can be expressed as: The length is It can be carried and transmitted in R1 time domain symbols. The positions of the frequency domain resources occupied in the R1 time domain symbols are the same; or, The frequency domain resources occupied in the R1 time domain symbols are independently configured, or, The positions of the frequency domain resources occupied in the R1 time domain symbols can be indicated by information.

[0096] Method 2: Generate the second data information through the following steps b1 to b2.

[0097] b1. Perform a first operation on the first data information to obtain third data information.

[0098] For example, the implementation of the above b1 can refer to the above a1, and will not be repeated here.

[0099] b2. Repeat the third data information R1 times to obtain the second data information, where R1 is a positive integer.

[0100] In the second approach, the third data information is the second sub-data information, that is, one piece of third data information can be carried in at least one time domain symbol for transmission.

[0101] For example, the second data information formed by repeating the third data information R1 times may be can be expressed as: The length is It can be carried and transmitted in R1 time domain symbols. The positions of the frequency domain resources occupied in the R1 time domain symbols are the same; or, The frequency domain resources occupied in the R1 time domain symbols are independently configured, or, The positions of the frequency domain resources occupied in the R1 time domain symbols can be indicated by information.

[0102] Method 3: Generate the second data information through the following steps c1 to c2.

[0103] c1. Divide the first data information into at least one first sub-data information.

[0104] The first sub-data information includes a plurality of consecutive data elements in the first data information.

[0105] It is understood that a first sub-data message can be used as a data block (Block), including all or part of the data information in the first data message. For example, when the first data message is divided into multiple first sub-data messages, the content of each first sub-data message is different, and the collection of multiple first sub-data messages constitutes the complete first data message; when the first data message is divided into one first sub-data message, the first sub-data message includes all the data information of the first data message.

[0106] For example, the first sub-data information with index i in the at least one first sub-data information can be represented as Length is i is an integer, and 0≤i≤I-1, and I is an integer greater than or equal to 1. It can be seen that when the value of i is 0, the number of first sub-data information is 1, that is, the first sub-data information is the first data information.

[0107] In some embodiments, the first sub-data information can be carried by a sequence. For example, assuming that the first sub-data information The length of is 4, then 4 2 = 16 sequences to carry different values ​​of the first sub-data information.

[0108] c2. For each first sub-data information, repeat the first sub-data information R1 times to obtain second data information, where R1 is a positive integer.

[0109] In the third mode, the first sub-data information is the second sub-data information, that is, one first sub-data information can be carried in at least one time domain symbol for transmission.

[0110] For example, the second data information formed by repeating the first sub-data information R1 times can be can be expressed as: The length is It can be carried and transmitted in R1 time domain symbols. The positions of the frequency domain resources occupied in the R1 time domain symbols are the same; or, Position-independent configuration of the frequency domain resources occupied in R1 time domain symbols; or, The positions of the frequency domain resources occupied in the R1 time domain symbols are indicated by information.

[0111] For example, as shown in FIG4 , assuming that R1 is 4, the second data information can be expressed as The second data information It can be carried in four time domain symbols (e.g., OFDM symbols) for transmission, and occupies resource 0, resource 1, resource 2, and resource 3 respectively. Resource 0 is in OFDM symbol 0, resource 1 is in OFDM symbol 1, resource 2 is in OFDM symbol 2, and resource 3 is in OFDM symbol 3. If the first communication node does not support frequency hopping, the positions of the frequency domain resources occupied by the four resources in the four OFDM symbols can be the same. If the first communication node supports frequency hopping, the positions of the frequency domain resources occupied by the four resources in the four OFDM symbols can be determined by the frequency domain hopping rule.

[0112] Method 4: Generate the second data information through the following d1 to d2.

[0113] d1. Perform a first operation on each bit in the first data information to obtain fourth data information.

[0114] Assume that the first data information can be expressed as: Then performing the first operation on each bit in the first data information means that, for the first data information b in i Perform the first operation to obtain the fourth data information Fourth data information It can be expressed as Fourth data information The length is bit; 0≤i≤L B -1.

[0115] Exemplarily, the first operation may include at least one of the following: bit-level repetition, encoding, modulation, interleaving, adding padding bits, and adding CRC bits.

[0116] For example, when the encoding includes Manchester encoding and the code rate is 1 / 4, when the first data information Middle B i = 0, b i Data information generated by Manchester encoding is [1 0 1 0]. When the first data information Middle B i =1, b i Data information generated by Manchester encoding is [0 1 0 1].

[0117] d2. Repeat the fourth data information R1 times to obtain the second data information, where R1 is a positive integer.

[0118] In the fourth mode, the fourth data information is the second sub-data information, that is, one fourth data information can be carried in at least one time domain symbol for transmission.

[0119] It should be noted that the embodiment of the present disclosure does not limit the execution order of d1 and d2. For example, the fourth method can also be implemented as follows: for each bit in the first data information, the bit is repeated R1 times; and then the first operation is performed on each bit after the repetition to obtain the fourth data information.

[0120] For example, the second data information obtained by repeating the fourth data information R1 times can be It can be expressed as:

[0121] For example, assuming R1 is 4, the second data information It can be expressed as The second data information The bearer may be transmitted in four time domain symbols (eg, OFDM symbols), and respectively occupy resource 0, resource 1, resource 2, and resource 3. Resource 0 is in OFDM symbol 0, resource 1 is in OFDM symbol 1, resource 2 is in OFDM symbol 2, and resource 3 is in OFDM symbol 3.

[0122] As shown in FIG5 , if the first communication node does not support frequency hopping, the positions of the frequency domain resources occupied by the four resources in the four OFDM symbols may be the same.

[0123] As shown in FIG6 , if the first communication node supports frequency hopping, the positions of the frequency domain resources occupied by the four resources in the four OFDM symbols can be configured independently, or a frequency domain hopping pattern can be used.

[0124] In some embodiments, one data element in the second data information corresponds to a sequence. Exemplarily, the sequence may be a scrambling sequence, a PN sequence, or a ZC sequence.

[0125] In some embodiments, each data element in the second data information corresponds to the same sequence. For example, the sequence may be a scrambling sequence, a PN sequence, or a ZC sequence.

[0126] In some embodiments, the sequences corresponding to the data elements with a value of 1 in the second data information are the same. For example, the above sequence may be a scrambling sequence, a PN sequence, or a ZC sequence.

[0127] In some embodiments, the sequences corresponding to the data elements at the same position in the fourth data information of R1 repeated in the second data information are the same. Exemplarily, the above sequence can be a scrambling sequence, a PN sequence, or a ZC sequence.

[0128] For example, when Manchester encoding is used and the code rate is 1 / 4, if the first data information Middle B i = 0, b i Data information generated by Manchester encoding is [1 0 1 0]. When the first data information Middle B i =1, b i Data information generated by Manchester encoding is [0 1 0 1]. In the embodiment of the present disclosure, the first data information Middle B i =1, the fourth data information generated by encoding Take [0 1 0 1] as an example for explanation.

[0129] Assume that the fourth data information When the number of repetitions R1 is 4, the second data information The expression of is.

[0130] In this embodiment, the second data information It can be carried in MC-OOK based LP-WUS symbol for transmission. One LP-WUS symbol carries the second data information A total of 16 LP-WUS symbols are required to carry the second data information.

[0131] For example, the time domain resources corresponding to 4 MC-OOK based LP-WUS symbols can be included in one OFDM symbol, and then 16 MC-OOK based LP-WUS symbols correspond to 4 OFDM symbols. The first (0 1 0 1) is sent in OFDM symbol 0 and occupies resource 0; the second (0 1 0 1) is sent in OFDM symbol 1 and occupies resource 1; the third (0 1 0 1) is sent in OFDM symbol 2 and occupies resource 2; and the fourth (0 1 0 1) is sent in OFDM symbol 3 and occupies resource 3. Resources 0, 1, 2, and 3 occupy the same frequency domain resources.

[0132] For example, the second data information The sequence of data elements configured in same.

[0133] For example, the second data information The sequence of data elements configured with '1' same.

[0134] For example, the second data information The fourth data information of R1 The sequence of data elements at the same position in the configuration Same. For example, The sequence corresponding to the first data element 0 in the first (0 1 0 1) is the same as the sequence corresponding to the first data element 0 in the second (0 1 0 1).

[0135] For example, the second data information The fourth data information of R1 The data elements at the same position in the sequence are configured as '1' Same. For example, The sequence corresponding to the second data element 1 in the first (0 1 0 1) is the same as the sequence corresponding to the second data element 1 in the second (0 1 0 1).

[0136] In some embodiments, the time domain expression of the MC-OOK based LP-WUS symbol may be generated according to the following e1 to e6.

[0137] e1. Assume that an OFDM symbol includes M MC-OOK based LP-WUS symbols, and assume that the data information sent on the M OOK symbols is S M , then define S M =[s0,s1,s2,s3,…,s M-1 ], with a length of M bits. M is an integer greater than or equal to 1.

[0138] For example, in the above embodiment, S M =[s0,s1,s2,s3,…,s M-1 ]=[0 1 0 1]. M=4.

[0139] e2. Data information S M Convert to data information Q K .Q K The length of is K bits, where K is greater than or equal to M.

[0140] As an implementation method, the data information S can be converted into M Convert to data information Q K .

[0141] M*A=K.

[0142] sequence It can be configured according to actual needs, 0≤i≤M-1.

[0143] K is the number of OFDM subcarriers configured in the frequency domain for the MC-OOK based LP-WUS symbol.

[0144] As another implementation method, the data information S can be converted into M Convert to data information Q K .

[0145] A0+A1+…+Ai+…+AM-1=K.

[0146] sequence It can be configured according to actual needs, 0≤i≤M-1.

[0147] K is the number of OFDM subcarriers configured in the frequency domain for the MC-OOK based LP-WUS symbol.

[0148] It can be understood that the above formulas (1) and (2) are only for generating data information Q K In other embodiments, other methods can be used to generate data information Q K , the embodiments of the present disclosure do not limit this.

[0149] e3. As shown in FIG7 , the data information Q K After K-point discrete Fourier transform (DFT) or fast Fourier transform (FFT), the data information D is obtained. K =[d0,d1,d2,d3,…,d K-1 ].

[0151] e5. As shown in FIG7 , for the padding data on the N subcarriers, perform N-point inverse discrete Fourier transform (IDFT) or inverse fast Fourier transform (IFFT) operations to obtain the time domain data T of N sampling points. N =[t0,t1,t2,t3,…,t N-1 ].

[0152] It is understandable that, in addition to the K OFDM subcarriers occupied by LP-WUS in the system's frequency domain bandwidth, other subcarriers can also be filled with other data information. Therefore, when the system frequency domain bandwidth includes N OFDM subcarriers, the time domain data T of N sampling points can be obtained by executing the above e5. N .

[0153] e6. Determine the time domain expression of the MC-OOK based LP-WUS symbol.

[0155] For example, as shown in FIG8 , [t0, t1, t2, t3, …, t N / M-1 ] is the sampling point data of the first OOK time domain symbol in M ​​OOK time domain symbols, [t NM ,t N / M+1 ,…,t 2N / M-1 ] is the sampling point data of the second OOK time domain symbol in M ​​OOK time domain symbols, and so on, [t (M-1)N / M ,t(M-1)N / M+1,…,t N-1 ] is the sampling point data of the Mth OOK time domain symbol among M OOK time domain symbols.

[0156] In some embodiments, when there is other data to be sent in addition to LP-WUS in the system, T N =[t0,t1,t2,t3,…,t N-1 ] is the superposition expression of the time domain symbol sampling point data of LP-WUS and other data.

[0157] The sampling point data of the first OOK time domain symbol among the M OOK time domain symbols is contained in [t0, t1, t2, t3, …, t N / M-1]. The sampling point data of the second OOK time domain symbol in the M OOK time domain symbols is contained in [t N / M ,t N / M+1 ,…,t 2N / M-1 ], and so on. The sampling point data of the Mth OOK time domain symbol in the M OOK time domain symbols is contained in [t (M-1)N / M ,t(M-1)N / M+1,…,t N-1 ]middle.

[0158] In some embodiments, the time domain data T of N sampling points N =[t0,t1,t2,t3,…,t N-1 ] Before sending, it is also necessary to perform the operation of adding a cyclic prefix (CP), that is, the time domain data T of N sampling points N The Ncp sampling point information at the end of the data is copied to the time domain data T of N sampling points N The time domain data of (N+Ncp) sampling points is formed, and then the time domain data of the (N+Ncp) sampling points is sent out.

Resource 0 is in OFDM symbol 0, resource 1 is in OFDM symbol 1, resource 2 is in OFDM symbol 2, and resource 3 is in OFDM symbol 3. The positions of the frequency domain resources occupied by the four resources in the four OFDM symbols can be the same.
