Description

Signal transmission methods, reception methods, communication nodes, and storage media Technical Field

[0001] This application relates to the field of communication technology, and in particular to a signal transmission method, a signal reception method, a communication node, and a storage medium. Background Technology

[0002] For communication systems, in addition to latency, reliability, and availability, the energy efficiency of user equipment (UE) is also crucial. Currently, UEs typically require charging weekly or daily depending on individual usage habits. Generally, UEs may consume tens of milliwatts of power when in Radio Resource Control (RRC) idle or inactive states, and hundreds of milliwatts when connected via RRC. Therefore, extending UE battery life is essential for improving energy efficiency and enhancing user experience. UE power consumption depends in part on the wake-up cycle length of its configured wake-up signal, such as the paging cycle. In related technologies, Extended Discontinuous Reception (eDRX) technology is used to save power while meeting energy consumption requirements, but this results in high latency for the wake-up signal.

[0038] It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0039] To meet battery life requirements, the 3rd Generation Partnership Project (3GPP) considered introducing an ultra-low power wake-up mechanism in the Rel-18 standard. The core of this mechanism is the Low Power Wake-Up Signal (LP-WUS), where the user uses a separate receiver to receive the LP-WUS signal, which wakes up the primary wireless device for data transmission and reception. When the user equipment does not detect the LP-WUS signal, the primary receiver remains in deep sleep, further reducing the user equipment's power consumption. The user equipment's power consumption depends in part on the wake-up period length of the configured wake-up signal, such as the paging period. To meet power consumption requirements, related technologies employ Extended Discontinuous Reception (eDRX) to save power, but this results in high latency for the wake-up signal.

[0040] eDRX offers a longer paging period than Discontinuous Reception (DRX), allowing user equipment to save power, but also resulting in longer downlink data latency. In eDRX, modules typically only listen to the paging channel within the paging time window (PTW) according to the DRX cycle to receive downlink services; outside the PTW, they are in sleep mode, not listening to the paging channel and unable to receive downlink services. In other words, eDRX involves modules continuously turning the receiver on and off; when the receiver is on, data can be received, and when the receiver is off, data cannot be received. The eDRX wake-up cycle consists of these two complete periods: turning the receiver off and turning it on.

[0041] Based on this, the technical solution provided in this application embodiment generates a first signal based at least on first information and first sequence information of a length of a first value. The first sequence information can be obtained based on second sequence information and / or variations of the second sequence information. In some examples, when the first signal is used as a wake-up signal, a shorter wake-up cycle can be configured for the wake-up signal, thereby reducing the wake-up signal latency while meeting the power consumption requirements of the user device.

[0042] Furthermore, the Internet of Things (IoT) has garnered significant attention in recent years. The interconnectivity of more objects promises to improve efficiency and quality of life. Manually replaceable or rechargeable batteries cannot meet the power needs of all IoT devices, leading to high maintenance costs, serious environmental problems, and even security risks in certain application scenarios. Therefore, 3GPP Rel-19 researches a new IoT technology (Ambient IoT) with a significantly higher connection count and / or device density than related 3GPP IoT technologies, while maintaining significantly lower complexity and power consumption than 3GPP Low-Power Wide-Area Network (LPWA) technologies such as Narrow Band Internet of Things (NB-IoT) and Long Term Evolution-Machine Type Communication (LTE-MTC). Therefore, the technical solutions provided in this application are also applicable to signaling and communication in Ambient IoT.

[0043] The signal transmission and reception methods provided in this application can be applied to various wireless communication systems, such as Long Term Evolution (LTE) systems (4th-Generation (4G) systems), New Radio (NR) systems (5th-Generation (5G) systems), LTE and NR hybrid architecture systems, and new communication systems that will emerge in future communication development, such as 6th-Generation (6G) systems.

[0044] For example, the communication system used in this application embodiment is shown in FIG1. ​​The communication system may include a first node 110 and a second node 120. The first node 110 may be a base station (BS) or a relay node performing relay functions. The second node 120 may be a user equipment (UE) or an intermediate node performing relay functions. The base station may include an evolved NodeB (eNB or eNodeB) in Long Term Evolution Advanced (LTEA), a Transmission Reception Point (TRP), a base station or gNB in ​​a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a Wireless Fidelity (WiFi) system, etc. The base station may also include various macro base stations, micro base stations, femtobase stations, wireless remote extensions, routers, WiFi devices, or various network-side devices such as primary cells and secondary cells, and Location Management Function (LMF) devices. It can also be a module or unit that performs some of the functions of a base station. For example, it can be a centralized unit (CU) or a distributed unit (DU). It should be noted that the embodiments of this application do not limit the specific form of the first node 110 and the second node 120.

[0045] Figure 2 is a schematic flowchart of a signal transmission method provided in an embodiment of this application. This signal transmission method can be applied, but is not limited to, the first node 110 in the communication system shown in Figure 1. As shown in Figure 2, the method may include, but is not limited to, the following S201:

[0046] S201. Send a first signal, the first signal being generated based at least on first information and first sequence information of a length of a first value.

[0047] The aforementioned first information is generated from source information through a specified processing procedure, which includes at least one of the following: segmentation, repetition, bit-level repetition, encoding, modulation, interleaving, adding padding bits, and adding Cyclic Redundancy Check (CRC) bits.

[0048] The first sequence information is obtained based on the second sequence information and / or a variation thereof. The first sequence information may include at least one of the following: the second sequence information, the first part, and the second part.

[0049] The first part can be a first number of sequence elements in the second sequence information, or a first number of zero elements, or a first number of predefined elements. Optionally, the first part can be a first number of sequence elements located at the end of the second sequence information.

[0050] The second part can be a second number of sequence elements in the second sequence information, or a second number of zero elements, or a second number of predefined elements. Optionally, the second part can be a second number of sequence elements located at the beginning of the second sequence information.

[0051] The second sequence information can be a binary random sequence, such as a ZC (Zadoff-Chu) sequence, a Maximum Length Linear Feedback Shift Register Sequence (M sequence), or a Pseudo Noise Sequence (PN sequence). The second sequence information can also be a repetition of a binary random sequence.

[0052] In some examples, the first sequence information can be obtained in at least one of the following combinations:

[0053] [Part 1, Second Sequence Information, Part 2];

[0054] [Part One, Second Sequence Information];

[0055] [Second sequence information, second part];

[0056] [Part Two, Second Sequence Information, Part One];

[0057] [Part Two, Second Sequence Information];

[0058] [Second sequence information, first part].

[0059] In some examples, the first sequence information can also be obtained by processing elements of the second sequence information. For example, multiplying, dividing, adding, and / or subtracting a data element from the sequence elements in the second sequence information, the processed second sequence information is determined as the first sequence information.

[0060] In some examples, the aforementioned first signal can be a Low Power Wake-Up Signal (LP-WUS), a Low Power Synchronization Signal (LP-SS), or a Low Power Preamble (LP-Preamble). Alternatively, the first signal can also be other types of signals, such as signaling and signals in Ambient IoT scenarios, which are not limited in the embodiments of this application.

[0061] The role of LP-WUS is to carry wake-up signal information. The purpose of the wake-up signal is to allow user equipment (UE) to detect the Wake-Up Signal (WUS) before a paging message arrives when it enters Idle (RRC_IDLE) mode, / or Inactive (RRC_INACTIVE) mode, and / or Connected (RRC_CONNECTED) mode. This allows the UE to activate its receiver to receive the paging message, preventing excessive power consumption caused by the UE checking for paging messages when none are present. Simultaneously, in Connected (RRC_CONNECTED) mode, the UE can also detect WUS to determine if scheduling has arrived. Upon detecting WUS, the UE activates its receiver to receive the Physical Downlink Control Channel (PDCCH), avoiding excessive power consumption by checking the PDCCH when no scheduling information is available. In short, the wake-up signal is an important energy-saving mechanism.

[0062] The functions of LP-SS include at least one of the following: performing Radio Resource Management (RRM) measurements by detecting LP-SS, performing downlink synchronization by detecting LP-SS, and performing frequency offset correction by detecting LP-SS.

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

[0064] Optionally, the transmission of LP-Preamble can take place before LP-WUS, and the terminal can perform downlink synchronization and / or frequency offset correction by detecting LP-Preamble, thereby improving the terminal's detection performance of LP-WUS.

[0065] The waveform of the aforementioned first signal (such as LP-WUS / LP-SS / LP-Preamble) can be generated using on-off keying (OOK) modulation. Therefore, the first signal can be referred to as OOK-based LP-WUS / LP-SS / LP-Preamble. Furthermore, in this application, the aforementioned first signal 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 domain is greater than one, the OOK-based LP-WUS / LP-SS / LP-Preamble can also be referred to as MC-OOK-based LP-WUS / LP-SS / LP-Preamble. Here, MC can be understood as multi-carrier or multi-subcarrier. MC-OOK is an implementation of OOK; therefore, the descriptions in the following embodiments no longer distinguish between OOK and MC-OOK, and the two concepts can be used interchangeably.

[0066] Next, taking MC-OOK based LP-WUS as the first signal as an example, the generation process of the first signal is introduced, as shown in Figure 3. The generation process of M MC-OOK based LP-WUS signals includes the following steps:

[0067] Step 1: The first message sent on M OOK symbols is S M Define S M =[S0,S1,S2,…,S M-1 And its length is M, where M is an integer greater than or equal to 1.

[0068] Step 2: According to certain rules, process the first information S with a length of the first value (e.g., M). M Convert to second information Q with a length of the second value k , where Q k The length is K, where K is an integer greater than or equal to 1.

[0069] Alternatively, the conversion rules here can be as follows:

[0070] ;or,

[0071] Where A0+A1+…A i +…+A M-1 =K, the above sequence The value of can be configured, where 0 ≤ i ≤ M-1. Here, the sequence... This can be understood as the first sequence of information.

[0072] Step 3: Transfer the second information Q k After K-point Discrete Fourier Transform (DFT) / Fast Fourier Transform (FFT) operations, the data information D is obtained. k , denoted as D k =[d0,d1,d2,d3,…,d K-1 ].

[0073] Furthermore, optionally, the data information D can also be... k Perform at least one of the following operations:

[0074] For D k Perform an upward circular shift operation, the size of which is Or K / 2.

[0075] For D k Perform a downward circular shift operation, the size of which is Or K / 2.

[0076] For D k Perform a left circular shift operation, the size of which is Or K / 2.

[0077] For D k Perform a right circular shift operation, the size of which is Or K / 2.

[0078] For D k Perform the FFT operation, where FFT is a function that shifts the zero-frequency component of the Fourier transform to the center of the spectrum. For a vector X, FFT(X) swaps the left and right halves of X or the top and bottom halves of X. For a matrix X, FFT(X) swaps the first and third quadrants, and the second and fourth quadrants.

[0079] in, This is the round-up operator. This is the floor operator.

[0080] Step 4: Transfer data information D kThe data is padded onto K subcarriers in the frequency domain. When the overall frequency bandwidth of the system includes N subcarriers, an N-point Inverse Discrete Fourier Transform (IDFT) / Inverse Fast Fourier Transform (IFFT) operation is performed on the padded data on the N subcarriers to obtain time-domain data T with N sampling points. N =[t0,t1,t2,t3,…,t N-1 ]. Where N is an integer greater than or equal to 1.

[0081] Among them, T N =[t0,t1,t2,t3,…,t N-1 ] is the sampling point data of M OOK time-domain symbols, that is, the time-domain representation of the first signal on an Orthogonal Frequency Division Multiplexing (OFDM) symbol.

[0082] Where, [t0,t1,t2,t3,…,t N / M-1 ] represents the sampling point data of the first OOK time-domain symbol out of M OOK time-domain symbols, [t N / M ,t N / M+1 ,…,t 2N / M-1 ] represents the sampling point data of the second OOK time-domain symbol out of M OOK time-domain symbols, and so on, [t (M-1)N / M ,t(M-1)N / M+1,…,t N-1 ] represents the sampling point data of the Mth OOK time-domain symbol out of M OOK time-domain symbols.

[0083] Furthermore, before performing the N-point IDFT / IFFT operation, at least one of the following operations can be performed on the data filled on the N subcarriers:

[0084] Perform an upward circular shift operation on the data, with the shift size being... Or N / 2.

[0085] Perform a downward circular shift operation on the data, with the shift size being... Or N / 2. Perform a left circular shift operation on the data, with the shift size being... Or N / 2.

[0086] Perform a right circular shift operation on the data, with the shift size being... Or N / 2.

[0087] The FFT operation is performed on the data, where FFT is a function used to shift the zero-frequency component of the Fourier transform to the center of the spectrum. For a vector X, FFT(X) swaps the left and right halves of X or swaps the top and bottom halves of X. For a matrix X, FFT(X) swaps the first and third quadrants, and the second and fourth quadrants.

[0088] Step 5: Time-domain data T from N sampling points N =[t0,t1,t2,t3,…,t N-1 Before sending, a CP (Cyclic prefix) operation can be performed, which involves adding a CP to the time-domain data T of N sampling points. N N at the tail CP The time-domain data T, which is copied from the information of one sampling point to N sampling points, is... N The head is removed, forming (N+N) CP The time-domain data of (N+N) sampling points, and then these (N+N) CP Data from ) sampling points is sent out.

[0089] Optionally, in step 4 above, when the number of frequency domain subcarriers allocated to the MC-OOK based LP-WUS symbol is not equal to K, for example, when the number of frequency domain subcarriers allocated to the MC-OOK based LP-WUS symbol is K1, where K1 is not equal to K, the generation process of the first signal can be as shown in Figure 4. Then, the process of step 4 is modified as follows:

[0090] (1) Data information D k =[d0,d1,d2,d3,…,d K-1 Process processing, D k Convert to E k1 , of which E k1 =[e0,e1,e2,e3,…,e k1-1 ].

[0091] Furthermore, it is also possible to analyze E k1 Perform at least one of the following operations:

[0092] For E k1 Perform an upward circular shift operation, the size of which is Or K1 / 2.

[0093] For E k1 Perform a downward circular shift operation, the size of which is Or K1 / 2.

[0094] For E k1 Perform a left circular shift operation, the size of which is Or K1 / 2.

[0095] For E k1 Perform a right circular shift operation, the size of which is Or K1 / 2.

[0096] For E k1 Perform the FFT operation, where FFT is a function used to shift the zero-frequency component of the Fourier transform to the center of the spectrum. For a vector X, FFT(X) swaps the left and right halves of X or swaps the top and bottom halves of X. For a matrix X, FFT(X) swaps the first and third quadrants, and the second and fourth quadrants.

[0097] in, This is the round-up operator. This is the floor operator.

[0098] (2) Transfer data information E k1 Fill the K1 subcarriers in the frequency domain.

[0099] (3) When the overall frequency domain bandwidth of the system includes N subcarriers, perform N-point IDFT / IFFT operations on the padding data on the N subcarriers to obtain time domain data T at N sampling points. N =[t0,t1,t2,t3,…,t N-1 ]. Where N is an integer greater than or equal to 1.

[0100] Among them, T N =[t0,t1,t2,t3,…,t N-1 ] is the sampling point data of M OOK time-domain symbols, that is, the time-domain representation of the first signal on an OFDM symbol.

[0101] Where, [t0,t1,t2,t3,…,t N / M-1 ] represents the sampling point data of the first OOK time-domain symbol out of M OOK time-domain symbols, [t N / M ,t N / M+1 ,…,t 2N / M-1 ] represents the sampling point data of the second OOK time-domain symbol out of M OOK time-domain symbols, and so on, [t (M-1)N / M ,t(M-1)N / M+1,…,t N-1 ] represents the sampling point data of the Mth OOK time-domain symbol out of M OOK time-domain symbols.

[0102] Furthermore, before performing the N-point IDFT / IFFT operation, at least one of the following operations can be performed on the data filled on the N subcarriers:

[0103] Perform an upward circular shift operation on the data, with the shift size being... Or N / 2.

[0104] Perform a downward circular shift operation on the data, with the shift size being... Or N / 2. Perform a left circular shift operation on the data, with the shift size being... Or N / 2.

[0105] Perform a right circular shift operation on the data, with the shift size being... Or N / 2.

[0106] The FFT operation is performed on the data, where FFT is a function used to shift the zero-frequency component of the Fourier transform to the center of the spectrum. For a vector X, FFT(X) swaps the left and right halves of X or swaps the top and bottom halves of X. For a matrix X, FFT(X) swaps the first and third quadrants, and the second and fourth quadrants.

[0107] in, This is the round-up operator. This is the floor operator.

[0108] In other embodiments, a process for generating a first signal is also provided. Taking MC-OOK based LP-WUS as an example, as shown in Figure 5, the process for generating M MC-OOK based LP-WUS signals includes the following steps:

[0109] Step 1: The first message sent on M OOK symbols is S M Define S M =[S0,S1,S2,…,S M-1 And its length is M, where M is an integer greater than or equal to 1.

[0110] Step 2: According to certain rules, process the first information S with a length of the first value (e.g., M). M Convert to second information of length two. (This process is not shown in Figure 5). Among them... The length of is K, where K is an integer greater than or equal to 1.

[0111] Alternatively, the conversion rules here can be as follows:

[0112] or,

[0113] in, Furthermore, The value of is equal to N, where N is the number of subcarriers included in the system bandwidth.

[0114] Among them, the above sequence The value of can be configured, where 0 ≤ i ≤ M-1. Here, the sequence... This can be understood as the first sequence of information.

[0115] Step 3: Transfer the second information After processing by the first processing module, data information D is obtained. k , denoted as D k =[d0,d1,d2,d3,…,d K-1 ].

[0116] The first processing module includes at least one of the following operations:

[0117] (1) Apply the following formula to the second information. The data information D is obtained through processing. k :

[0118] in, Optionally, Let F be the generalized inverse matrix. Where (X) -1 To find the inverse of matrix X, (X) is the operation. H To find the conjugate transpose of matrix X, (X) T To find the transpose of matrix X, perform the matrix operation.

[0119] Where F is a matrix consisting of K columns of elements in the IDFT matrix, matrix F is A matrix with K rows and K columns.

[0120] The expression for the IDFT matrix is:

[0121] or,

[0122] Furthermore, the K columns of elements in the IDFT matrix that make up F are in the IDFT matrix. The position of a column element is determined at least by the data information D. k The positions or indices of the K subcarriers filled into the frequency domain are determined.

[0123] (2) It can also be used for data information D k Perform at least one of the following operations:

[0124] For D kPerform an upward circular shift operation, the size of which is Or K / 2.

[0125] For D k Perform a downward circular shift operation, the size of which is Or K / 2.

[0126] For D k Perform a left circular shift operation, the size of which is Or K / 2.

[0127] For D k Perform a right circular shift operation, the size of which is Or K / 2.

[0128] For D k Perform the FFT operation, where FFT is a function used to shift the zero-frequency component of the Fourier transform to the center of the spectrum. For a vector X, FFT(X) swaps the left and right halves of X or swaps the top and bottom halves of X. For a matrix X, FFT(X) swaps the first and third quadrants, and the second and fourth quadrants.

[0129] in, This is the round-up operator. This is the floor operator.

[0130] Step 4: Transfer data information D k The data is padded onto K subcarriers in the frequency domain. When the overall frequency bandwidth of the system includes N subcarriers, N-point IDFT / IFFT operations are performed on the padded data on the N subcarriers to obtain time-domain data T at N sampling points. N =[t0,t1,t2,t3,…,t N-1 ]. Where N is an integer greater than or equal to 1.

[0131] Among them, T N =[t0,t1,t2,t3,…,t N-1 ] is the sampling point data of M OOK time-domain symbols, that is, the time-domain representation of the first signal on an OFDM symbol.

[0132] Where, [t0,t1,t2,t3,…,t N / M-1 ] represents the sampling point data of the first OOK time-domain symbol out of M OOK time-domain symbols, [t N / M ,t N / M+1 ,…,t 2N / M-1 ] represents the sampling point data of the second OOK time-domain symbol out of M OOK time-domain symbols, and so on, [t (M-1)N / M,t(M-1)N / M+1,…,t N-1 ] represents the sampling point data of the Mth OOK time-domain symbol out of M OOK time-domain symbols.

[0133] Step 5: Time-domain data T from N sampling points N =[t0,t1,t2,t3,…,t N-1 Before sending, a CP operation can also be performed, which involves adding time-domain data T from N sampling points. N N at the tail CP The time-domain data T, which is copied from the information of one sampling point to N sampling points, is... N The head is removed, forming (N+N) CP The time-domain data of (N+N) sampling points, and then these (N+N) CP Data from ) sampling points is sent out.

[0134] Optionally, in step 4 above, when the number of frequency domain subcarriers allocated to the MC-OOK based LP-WUS symbol is not equal to K, for example, when the number of frequency domain subcarriers allocated to the MC-OOK based LP-WUS symbol is K1, where K1 is not equal to K, then the process of step 4 is modified as follows:

[0135] (1) Data information D k =[d0,d1,d2,d3,…,d K-1 Process D k Convert to E k1 , of which E k1 =[e0,e1,e2,e3,…,e k1-1 ].

[0136] (2) Transfer data information E k1 Fill the K1 subcarriers in the frequency domain.

[0180] Based on the above embodiments, optionally, the cyclic shift value is determined according to at least one of the following methods:

[0181] Method 1: Determine the cyclic shift value based on the cyclic shift interval value.

[0182] Here, the cyclic shift interval refers to the distance between two cyclic shift values. Optionally, based on the cyclic shift interval Gap, the cyclic shift value C can be determined using the following formula. v Cv =v·Gap;

[0183] in,

[0184] Alternatively, based on the cyclic shift interval value Gap, the cyclic shift value C can also be determined using the following formula. v C v =a + v·Gap;

[0185] Where a is an integer greater than or equal to 0.

[0186] Method 2: Determine the cyclic shift value based on the second indication information. The second indication information is used to indicate the root index value and / or the cyclic shift value.

[0195] For example, assuming the number of second sequence information is 4 and the index indicated by the second indication information is 0, then the indices corresponding to these 4 pieces of second sequence information are 0, 1, 2, and 3 respectively.

[0196] First, based on the index indicated by the second instruction information, query Table 1, Table 2, or Table 3 to obtain the root index value and circular shift value corresponding to each second sequence information. The specific table to query can be determined in conjunction with the transmission method of the first signal. For example, if the first signal uses the first transmission method, Table 1 can be queried; if the first signal uses the second transmission method, Table 2 can be queried; and if the first signal uses the third transmission method, Table 3 can be queried.

[0197] Next, based on the root index value q and the sequence length B of the second sequence information... zc Generate sequence X according to the following formula q (m):

[0198] Furthermore, based on the cyclic shift value C corresponding to each second sequence information... v For sequence X q (m) Perform a circular shift operation to generate four second sequence information X. q ′(m):

[0199] X q ′(m)=X q ((m+C v )mod B zc ), m=0,1,…,B zc -1.

[0200] It should be noted that the above table showing the correspondence between the root index value and / or the circular shift value indicated by the second indication information is only an example. Other methods can also be used to show the correspondence between the root index value and / or the circular shift value indicated by the second indication information. The value of the "index" column in the above table is only an illustration and can be replaced with other index values. This application embodiment does not limit this.

[0201] Based on the above embodiments, optionally, the above-mentioned cyclic shift interval value can be determined by at least one of the following methods:

[0205] Optionally, the length of the third indication information is related to the subcarrier spacing. Optionally, the length of the third indication information corresponding to a subcarrier spacing of 15 kHz and / or 30 kHz is greater than or equal to the length of the third indication information corresponding to a subcarrier spacing of 60 kHz and / or 120 kHz.

[0206] Optionally, the length of the third indication information corresponding to a subcarrier spacing of 15 kHz and / or 30 kHz is 3 or 4.

[0207] Optionally, the length of the third indication information corresponding to a subcarrier spacing of 60 kHz and / or 120 kHz is 2 or 3.

[0208] Method 2: Determine the cyclic shift interval value based on the cyclic shift interval index and the subcarrier interval.

[0209] Optionally, for the same subcarrier interval, the cyclic shift interval values ​​corresponding to adjacent cyclic shift interval indices are in a multiple relationship;

[0210] For the same cyclic shift interval index, when multiple subcarrier intervals are in a multiple relationship, the cyclic shift interval values ​​corresponding to the multiple subcarrier intervals are in a multiple relationship.

[0211] Optionally, the cyclic shift interval value is less than or equal to 63, or the cyclic shift interval value is less than or equal to 65.

[0212] Optionally, when the subcarrier spacing is equal to 120 kHz, the cyclic shift interval value is 0, 16, 31 or 63;

[0213] With a subcarrier spacing of 60kHz, the cyclic shift interval can be 0, 8, 16, 31, or 63.

[0214] With a subcarrier spacing of 30kHz, the cyclic shift interval can be 0, 4, 8, 16, 39, or 63.

[0215] With a subcarrier spacing of 15kHz, the cyclic shift interval can be 0, 2, 4, 8, 20, 40, or 63.

[0216] When the subcarrier spacing is equal to 120kHz, the cyclic shift interval value is 0, 16, 31 or 65;

[0217] With a subcarrier spacing of 60kHz, the cyclic shift interval can be 0, 8, 16, 31 or 65.

[0218] With a subcarrier spacing of 30kHz, the cyclic shift interval can be 0, 4, 8, 16, 39, or 65.

[0219] With a subcarrier spacing of 15kHz, the cyclic shift interval can be 0, 2, 4, 8, 20, 40, or 65.

[0220] When the subcarrier spacing is 60kHz and / or 120kHz, the cyclic shift interval is 0 or the default value.

[0221] Optionally, the correspondence between the cyclic shift interval index, the subcarrier interval, and the cyclic shift interval value can be as shown in Table 4 or Table 5 below:

[0222] Table 4

[0223] Table 5

[0224] It should be noted that the above table showing the correspondence between the cyclic shift interval index, subcarrier interval, and cyclic shift interval value is only an example. Other methods can also be used to show the correspondence between the cyclic shift interval index, subcarrier interval, and cyclic shift interval value. Furthermore, the value of the "Gap Index" column in the above table is only an illustration and can be replaced with other index values. This application embodiment does not limit this.

[0225] In some examples, the second sequence information can be generated according to the following procedure:

[0226] For example, suppose the length of the required second sequence information is B. zc =127, the required amount of second sequence information is 4, the first root index value q=1, the gap index is 3 and the subcarrier spacing is 30kHz, then by querying Table 4 or Table 5 above, the cyclic shift interval value can be obtained as 16.

[0227] First, based on the root index value q and the sequence length B of the second sequence information... zc Generate sequence X according to the following formula q (m):

[0228] Next, according to C v =v·Gap, which determines the available cyclic shift values, including [0, 16, 32, 48, 64, 80, 96]. Wherein...

[0229] Since the required amount of second sequence information in this embodiment is 4, the first 4 cyclic shift values ​​can be selected from the available cyclic shift values ​​to generate the second sequence information, i.e., the cyclic shift values ​​used to generate the second sequence information are [0, 16, 32, 48]. Of course, any 4 cyclic shift values ​​can be selected from the available cyclic shift values, and this embodiment does not limit this.

[0230] Furthermore, based on the four cyclic shift values, the above sequence X is processed using the following formulas respectively. q (m) Perform a shift operation to obtain 4 second sequence information. X q ′(m)=X q ((m+C v )mod B zc ), m=0,1,…,B zc -1.

[0231] For example, suppose the length B of the second sequence information is... zc =127, the number of second sequence information is 4, the first root index value q=1, the gap index is 4 and the subcarrier spacing is 30kHz, then by querying Table 4 or Table 5 above, the cyclic shift interval value can be obtained as 39.

[0232] First, based on the root index value q and the sequence length B of the second sequence information... zc Generate sequence X according to the following formula q (m):

[0233] Next, according to C v =v·Gap, which determines the available cyclic shift values, including [0, 39, 78].

[0234] Since the required number of second sequence information is 4, and in this embodiment, one root index value corresponds to only 3 cyclic shift values ​​used to generate the second sequence information, meaning that 3 cyclic shift values ​​can only generate 3 pieces of second sequence information, which is insufficient for the required 4 pieces of second sequence information, the following process can be used to address this situation:

[0235] (1) The root index value q of the first 3 of the 4 second sequence information is set to 1. Based on the 3 cyclic shift values ​​[0, 39, 78] corresponding to the above root index value, 3 second sequence information X are generated respectively according to the following formula. q ′(m): X q ′(m)=X q ((m+C v )mod B zc), m=0,1,…,B zc -1.

[0236] (2) The root index value of the second sequence information in the fourth item can be any other value in the set of root index values. For example, it can be the root index value after q=1 in the set of root index values, such as q=2; the cyclic shift value of the second sequence information in the fourth item can be any one of the above-mentioned available cyclic shift values ​​[0, 39, 78]. For example, the first cyclic shift value, i.e., C, can be taken. v =0; then based on q=2 and C v =0, generate the fourth second sequence information X according to the following formula. q ′(m): X q ′(m)=X q ((m+C v )mod B zc ), m=0,1,…,B zc -1.

[0237] In other words, the principle for generating multiple second sequence information is as follows: (1) Select a cyclic shift value that satisfies the number of second sequence information from the available cyclic shift values ​​corresponding to the first root index value, and then generate the corresponding number of second sequence information based on the first root index value and the selected cyclic shift value. (2) If the number of available cyclic shift values ​​corresponding to the first root index value is less than the required number of second sequence information, other root index values ​​can be selected from the set of root index values, and at least one cyclic shift value can be selected from the available cyclic shift values ​​corresponding to the other root index values. Second sequence information can be generated based on the other root index values ​​and the selected at least one cyclic shift value until the required number of second sequence information is met.

[0238] Method 3: Determine the cyclic shift interval value based on the transmission method of the first signal, the cyclic shift interval index, and the subcarrier interval.

[0239] Optionally, when the first signal adopts the first transmission mode, for the same subcarrier interval, the cyclic shift interval values ​​corresponding to adjacent cyclic shift interval indices are in a multiple relationship;

[0240] For the same cyclic shift interval index, when multiple subcarrier intervals are in a multiple relationship, the cyclic shift interval values ​​corresponding to the multiple subcarrier intervals are in a multiple relationship.

[0241] Optionally, when the first signal adopts a first transmission mode (e.g., the first transmission mode is OOK, M=1), the correspondence between the cyclic shift interval value and the subcarrier interval includes at least one of the following:

Therefore, the specific implementation of the relevant embodiments of the above signal receiving method can refer to the specific implementation of the signal sending method in the above embodiments.
