[0040] For example, a communication system 100 used in an embodiment of the present application is shown in FIG1 . The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal or terminal).

[0041] FIG1 exemplarily shows a network device and two terminal devices. Optionally, the communication system 100 may include multiple network devices and each network device may include another number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0042] Optionally, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

[0043] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system 100 shown in FIG1 as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function. The network device 110 and the terminal device 120 may be the specific devices described above and will not be described in detail here. The communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.

[0044] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0045] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0046] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and indication, configuration and configuration, etc.

[0047] In the embodiments of the present application, "pre-defined" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device or a network device). The present application does not limit the specific implementation method. For example, pre-defined may refer to information defined in a protocol.

[0048] In the embodiments of the present application, the "protocol" may refer to a standard protocol in the communication field, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0049] The 3rd Generation Partnership Project (3GPP) further generates corresponding scrambling sequences or reference signals based on the Gold sequence of length 31. The Gold sequence c of length 31 is generated as follows:

[0050] c(n)=(x1(n+NC )+x2(n+N C ))mod2

[0051] x1(n+31)=(x1(n+3)+x1(n))mod2

[0052] x2(n+31)=(x2(n+3)+x2(n+2)+x2(n+1)+x2(n))mod2

[0053] Among them, N C =1600, the initial value of the first sequence x1(n) is x1(0)=1, x1(n)=0, n=1, 2, ..., 30, and the initial value of the second sequence x2(n) is Initial seed C for random sequence generation init The determination of the time domain resource number is typically determined by one or more parameters, such as the time domain resource number and an identification parameter. The identification parameter is configured for the terminal via the network or is predefined. The predefined identification parameter and time parameter are known to non-target terminals, while the identification parameter configured by the network device is specific to the target terminal. However, since the identification parameter is sent to the terminal device over the air interface, it may be intercepted by non-target terminals. Consequently, the initial seed may be obtained by the non-target terminal, and the sequence sent to the target terminal may be known. This poses security risks such as information leakage, theft, and imitation.

[0054] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0055] FIG2 is a schematic diagram of a method 200 for generating a sequence according to an embodiment of the present application. As shown in FIG2 , the method 200 includes the following contents:

[0056] S210: The transmitting end device generates an initial seed of a target sequence according to target channel information.

[0057] In some embodiments, the target channel information may refer to a dedicated parameter of the link between the transmitting device and the receiving device. That is, only the transmitting device and the receiving device corresponding to the link can know the parameter. Therefore, the target sequence initial seed generated based on the parameter is conducive to reducing the security risk of information leakage.

[0058] In some embodiments, the target channel information may be the channel information of the link between the transmitting device and the receiving terminal. In some specific embodiments, it may include the channel state information (CSI) of the link between the transmitting device and the receiving terminal, or it may be other channel information of the link. This application does not limit this.

[0059] In some specific embodiments, the channel state information may include but is not limited to at least one of the following:

[0060] Channel Quality Indicator (CQI), Rank Indication (RI), Precoding Matrix Indicator (PMI).

[0061] In some embodiments, the transmitting device and the receiving device are both terminal devices.

[0062] In other embodiments, the sending device is a terminal device, and the receiving device is a network device.

[0063] In some further embodiments, the sending device is a network device, and the receiving device is a terminal device.

[0064] In some embodiments, for a transmitting device, the target sequence initial seed is used to generate a target sequence.

[0065] In some embodiments, the transmitting end device of the target sequence may generate a target sequence initial seed according to the target channel information, further generate a target sequence based on the target sequence initial seed, and transmit the target sequence.

[0066] In some embodiments, for a receiving device, the target sequence initial seed is used to detect the target sequence.

[0067] In some embodiments, the receiving device of the target sequence may generate a target sequence initial seed according to target channel information, and further detect the target sequence based on the target sequence initial seed to determine whether the transmitting device sends the target sequence or uses it for channel estimation.

[0068] It should be understood that in the embodiment of the present application, the way in which the receiving device generates the initial seed of the target sequence is the same as the way in which the sending device generates the initial seed of the target sequence. The following describes the way in which the initial seed of the target sequence is generated from the perspective of the sending device, but the present application is not limited to this.

[0069] In some embodiments, the link between the transmitting device and the receiving device satisfies channel reciprocity. That is, the channel fading experienced by the transmitting device when transmitting a signal to the receiving device and the channel fading experienced by the receiving device when transmitting a signal to the transmitting device can be considered to be the same. In other words, the target channel information determined by the transmitting device and the target channel information determined by the receiving device can be considered to be the same.

[0070] In some embodiments, the target channel information includes channel information on N frequency domain units, where N is a positive integer.

[0071] In some embodiments, the frequency domain unit can be a frequency point, or it can be a certain range of frequency domain resources. In some specific embodiments, the frequency domain unit includes but is not limited to at least one of the following: subcarrier, resource block (RB), subband, bandwidth part (BWP), carrier.

[0072] It should be understood that the present application does not limit the method for obtaining the target channel information. In some embodiments, the target channel information can be obtained through channel measurement, for example, by measuring the reference signal on the link between the transmitting device and the receiving device.

[0073] It should be noted that in an embodiment of the present application, the target channel information can also be replaced by other parameters exclusive to the transmitting device and the receiving device, for example, characteristic parameters of the transmitting device and characteristic parameters of the receiving device, such as product number, or chip number, etc., or other physical layer parameters between the transmitting device and the receiving device. This application does not limit this.

[0074] In some embodiments of the present application, the target sequence initial seed may be generated based solely on the target channel information, or may be generated based on the target channel information and other parameters, for example, based on time parameters, configuration parameters, predefined parameters, etc., which is not limited in the present application.

[0075] In some embodiments, the time parameter includes but is not limited to at least one of the following:

[0076] The symbols, time slots, subframes, and frames occupied by the target sequence initial seed (or target sequence).

[0077] In some embodiments, the configuration parameters may be parameters configured by a network device, and in some specific embodiments, may include but are not limited to a cell identifier.

[0078] In some embodiments, the predefined parameters are predefined parameters that can be known by the transmitting and receiving devices without requiring network device configuration. In some specific embodiments, this can be achieved by pre-storing corresponding codes, tables, or other methods that can be used to indicate predefined parameters in the transmitting and receiving devices. This application does not limit the specific implementation method. For example, the predefined parameters can refer to parameters defined in the protocol.

[0079] The following describes how to generate the target sequence initial seed in combination with Example 1 and Example 2.

[0080] Embodiment 1: The target sequence initial seed is generated according to the target channel information.

[0081] In some embodiments of the present application, the S210 includes:

[0082] An initial seed of a target sequence is generated according to the characteristic information (or feature information, attribute information) of the target channel information.

[0083] Optionally, the characteristic information of the target channel information may include part or all of the characteristics of the target channel information. For example, if the target channel information is vector information, the characteristic information of the target channel information may include characteristic information of the target channel information in a specific direction.

[0084] In some embodiments, the characteristic information of the target channel information includes but is not limited to at least one of the following:

[0085] Amplitude information of target channel information, phase information of target channel information, and mapping information (or projection information, quantization information) of target channel information on a specific domain.

[0086] In some embodiments, the specific domain includes but is not limited to the Fourier transform (FT) domain, and in some specific embodiments may include the fast Fourier transform (FFT) domain and the discrete Fourier transform (DFT) domain.

[0087] Example 1-1: The target sequence initial seed is generated according to the amplitude information of the target channel information.

[0088] In some embodiments, generating the target sequence initial seed according to the characteristic information of the target channel information includes:

[0089] An initial seed of a target sequence is generated according to amplitude information of channel information on N frequency domain units.

[0090] In some specific embodiments, the amplitude information of the channel information on the N frequency domain units may be quantized to obtain N amplitude quantization values, and the target sequence initial seed may be generated based on at least one amplitude quantization value of the N amplitude quantization values.

[0091] It should be understood that the present application is not limited to the quantization method of the amplitude information of the channel information on the N frequency domain units.

[0092] As an example, according to the first amplitude threshold, the amplitude information of the channel information on the N frequency domain units is binary quantized to obtain the N amplitude quantization values.

[0093] For example, if the channel information H(n) on the nth frequency domain unit among the channel information on N frequency domain units is expressed as:

[0094] H(n)=A(n)e jθ(n) ,n=0,1,2…N-1, where A(n) represents the amplitude information of the channel information on the nth frequency domain unit, and θ(n) represents the phase information of the channel information on the nth frequency domain unit. Further, the transmitting end device can be based on the first amplitude threshold A th1 Perform binary quantization on A(n). For example, if A(n) is greater than A th1 , quantize A(n) to A′(n)=1, otherwise, quantize A(n) to A′(n)=0.

[0095] As another example, the amplitude information of the channel information on the N frequency domain units is rounded (for example, rounded up or rounded down) to obtain N amplitude quantization values.

[0096] For example, if the channel information H(n) on the nth frequency domain unit among the channel information on N frequency domain units is expressed as:

[0097] H(n)=A(n)e jθ(n) ,n=0,1,2…N-1, where A(n) represents the amplitude information of the channel information on the nth frequency domain unit, and θ(n) represents the phase information of the channel information on the nth frequency domain unit. Further, the transmitting end device can quantize A(n) as or

[0098] As another example, the amplitude information of the channel information on the N frequency domain units is modulo processed with a second amplitude threshold to obtain the N amplitude quantization values.

[0099] For example, if the channel information H(n) on the nth frequency domain unit among the channel information on N frequency domain units is expressed as:

[0100] H(n)=A(n)e jθ(n) ,n=0,1,2…N-1, where A(n) represents the amplitude information of the channel information on the nth frequency domain unit, and θ(n) represents the phase information of the channel information on the nth frequency domain unit. Further, the transmitting end device can be based on the second amplitude threshold A th2 Perform modulo quantization on A(n), for example, quantize A(n) to A′(n)=A(n)mod A th2 .

[0101] Furthermore, in some embodiments, the transmitting device may use one of the N amplitude quantization values ​​as the target sequence initial seed, or may generate the target sequence initial seed based on multiple amplitude quantization values. For example, the target sequence initial seed may be obtained by processing the multiple amplitude quantization values. The processing may include, but is not limited to, accumulation, multiplication, Fourier transform, modulo, etc.

[0102] As an example, the sending device can generate the target sequence initial seed according to the following formula: Wherein, C represents the initial seed of the target sequence, A′(i) represents the amplitude quantization value of the channel information on the i-th frequency domain unit among the N frequency domain units, Q is an integer, and A′(n) represents the amplitude quantization value of the channel information on the n-th frequency domain unit among the N frequency domain units.

[0103] Embodiment 1-2: The target sequence initial seed is generated according to the phase information of the target channel information.

[0104] In some embodiments, generating the target sequence initial seed according to the characteristic information of the target channel information includes:

[0105] An initial seed of a target sequence is generated according to phase information of channel information on N frequency domain units.

[0106] In some specific embodiments, the phase information of the channel information on the N frequency domain units may be quantized to obtain N phase quantization values, and the target sequence initial seed may be generated based on at least one phase quantization value of the N phase quantization values.

[0107] It should be understood that the present application is not limited to the quantization method of the phase information of the channel information on the N frequency domain units.

[0108] As an example, according to the first phase threshold, the phase information of the channel information on the N frequency domain units is binary quantized to obtain the N phase quantization values.

[0109] For example, if the channel information H(n) on the nth frequency domain unit among the channel information on N frequency domain units is expressed as:

[0110] H(n)=A(n)e jθ(n) ,n=0,1,2…N-1, where A(n) represents the amplitude information of the channel information on the nth frequency domain unit, and θ(n) represents the phase information of the channel information on the nth frequency domain unit. Further, the transmitting end device can be based on the first phase threshold θ th1 Binary quantize θ(n), for example, if θ(n) is greater than θ th1 , quantize θ(n) to θ′(n)=1, otherwise, quantize θ(n) to θ′(n)=0.

[0111] As another example, the phase information of the channel information on the N frequency domain units is rounded (eg, rounded up or rounded down) to obtain the N phase quantization values.

[0112] For example, if the channel information H(n) on the nth frequency domain unit among the channel information on N frequency domain units is expressed as:

[0113] H(n)=A(n)e jθ(n) ,n=0,1,2…N-1, where A(n) represents the amplitude information of the channel information on the nth frequency domain unit, and θ(n) represents the phase information of the channel information on the nth frequency domain unit. Further, the transmitting end device can quantize θ(n) as or

[0114] As another example, the phase information of the channel information on the N frequency domain units is modulo processed with a second phase threshold to obtain the N phase quantization values.

[0115] For example, if the channel information H(n) on the nth frequency domain unit among the channel information on N frequency domain units is expressed as:

[0116] H(n)=A(n)e jθ(n) ,n=0,1,2…N-1, where A(n) represents the amplitude information of the channel information on the nth frequency domain unit, and θ(n) represents the phase information of the channel information on the nth frequency domain unit. Further, the transmitting end device can be based on the second phase threshold θ th2 Perform modulo quantization on A(n), for example, quantize θ(n) to θ′(n)=θ(n)modθ th2 .

[0117] In some embodiments, the transmitting device may use one of the N phase quantization values ​​as the target sequence initial seed, or may generate the target sequence initial seed based on multiple phase quantization values. For example, the target sequence initial seed may be obtained by processing the multiple phase quantization values. The processing may include, but is not limited to, accumulation, multiplication, Fourier transform, modulo, etc.

[0118] As an example, the sending device generates the target sequence initial seed according to the following formula: Wherein, C represents the initial seed of the target sequence, θ′(i) represents the phase quantization value of the channel information on the i-th frequency domain unit among the N frequency domain units, P is an integer, and θ′(n) represents the phase quantization value of the channel information on the n-th frequency domain unit among the N frequency domain units.

[0119] Embodiment 1-3: The target sequence initial seed is generated according to the mapping information of the target channel information in the specific domain.

[0120] The following description is given by taking the FFT domain as an example, but the present application is not limited thereto.

[0121] In some embodiments of the present application, the S210 may include:

[0122] An initial seed of a target sequence is generated according to mapping information of channel information on N frequency domain units on a Fourier transform domain.

[0123] In some embodiments, the codebook may be considered as an FFT domain, and the mapping information of the target channel information in the FFT domain may be represented by the codebook mapped by the target channel information in the FFT domain.

[0124] In some specific embodiments, the transmitting device may determine, in the candidate codebook set, a target codebook corresponding to the channel information on each frequency domain unit based on the channel information on each frequency domain unit in the N frequency domain units, wherein the index information of the target codebook corresponding to the channel information on each frequency domain unit is used to represent the mapping information of the channel information on each frequency domain unit in the Fourier transform domain.

[0125] Furthermore, the target sequence initial seed is generated according to index information of a target codebook corresponding to channel information on at least one frequency domain unit among the N frequency domain units.

[0126] It should be understood that in the embodiments of the present application, at least one may refer to one or more, wherein a plurality may refer to two or more.

[0127] It should be understood that the embodiments of the present application do not limit the specific method of determining the target codebook corresponding to the channel information on each frequency domain unit in the candidate codebook set. In some embodiments, the target codebook can be determined based on the size of the inner product between the channel information on the frequency domain unit and the candidate codebooks in the candidate codebook set. In a specific embodiment, the codebook with the largest inner product with the channel information on the frequency domain unit in the candidate codebook set is determined as the target codebook.

[0129] H a*b (n) = A(n)e jθ(n) ,n=0,1,2…N-1, where A(n) represents the amplitude information of the channel information on the nth frequency domain unit, θ(n) represents the phase information of the channel information on the nth frequency domain unit, a represents the transmitting antenna, and b represents the receiving antenna. Furthermore, the transmitting end device can determine the adapted H in the candidate codebook set. a*b (n) target codebook, wherein in the candidate codebook set, the target codebook and H a*b The inner product of (n) is the largest.

[0130] For example, as shown in Table 1, the candidate codebook set may include a candidate codebook set consisting of 256 codebooks, and the indexes i1 and i2 (corresponding to the above-mentioned index information) corresponding to each codebook can be used to represent the codebook. The target codebook corresponding to the channel information on the nth frequency domain unit among the N frequency domain units can be identified by i1(n) and i2(n). The indexes i1(n) and i2(n) corresponding to the codebook can be used as the mapping information of the channel information on the nth frequency domain unit in the FFT domain.

[0137] It should be understood that the above embodiments 1-1 to 1-3 can be implemented separately or in combination. In some embodiments, the transmitting end device can generate the target sequence initial seed based on the amplitude information and phase information of the target channel information, or can generate the target sequence initial seed based on the amplitude information of the target channel and the mapping information in a specific domain, or can generate the target sequence initial seed based on the amplitude information, phase information of the target channel and the mapping information in a specific domain, etc. As an example, the target sequence initial seed is generated according to the following formula:

[0140] It should be understood that in an embodiment of the present application, the target channel information may include channel information on N frequency domain units, or may also include channel information on M other domain units (such as spatial domain), and the present application does not limit this.

[0141] Embodiment 2: The target sequence initial seed is generated based on target channel information and other parameters.

[0142] In some embodiments, the transmitting device may generate an initial seed of the target sequence based on the target channel information and a first parameter, wherein the first parameter includes at least one of a time parameter, a configuration parameter, and a predefined parameter.

[0143] In some embodiments, the transmitting device first generates a first sequence initial seed according to the target channel information, and further generates a target sequence initial seed according to the first sequence initial seed and the first parameter.

[0144] In some specific embodiments, the first sequence initial seed and the first parameter may be processed by accumulation, multiplication, modulo, or Fourier transformation to generate the target sequence initial seed.

[0145] In some other embodiments, the transmitting device first generates a second sequence initial seed based on the first parameter, and further generates a target sequence initial seed based on the second sequence initial seed and the target channel information. As an example, the target sequence initial seed is generated based on feature information of the second sequence initial seed and the target channel information.

[0146] It should be understood that in this embodiment 2, the specific implementation of generating the first sequence initial seed according to the target channel information refers to the relevant implementation of generating the target sequence initial seed according to the target channel information in embodiment 1, and for the sake of brevity, it is not repeated here.

[0147] For example, a first sequence of initial seeds is generated according to characteristic information of the target channel information.

[0148] As an example, the first sequence of initial seeds is generated according to at least one of amplitude information, phase information, and mapping information on a specific domain of the target channel information.

[0149] Embodiment 2-1: The target sequence initial seed is generated based on the target channel information and time parameters.

[0150] In some embodiments, the transmitting end device first quantizes the channel information on N frequency domain units included in the target channel information, and further generates an initial seed of the target sequence based on the time parameter and the quantized channel information.

[0151] For example, if the channel information H(n) on the nth frequency domain unit among the channel information on N frequency domain units is expressed as:

[0152] H(n)=A(n)e jθ(n), n=0,1,2…N-1, where A(n) represents the amplitude information of the channel information on the nth frequency domain unit, and θ(n) represents the phase information of the channel information on the nth frequency domain unit. Further, the transmitting end device may quantize H(n) to obtain H′(n). For the specific quantization method, refer to the specific implementation of Example 1. Further, the transmitting end device processes H′(n), n=0,1,…N to obtain a first sequence initial seed M, for example, M=f(H′(n)), where f is a function, which may be an accumulation function, a multiplication function, or a Fourier transform function, etc., and this application does not limit this.

[0153] Furthermore, the transmitting device obtains the target sequence initial seed according to the formula C = g(M, T), where g is a sequence generation function, such as accumulation, multiplication, modulo, or Fourier transform. T is a time parameter, such as the symbol, time slot, subframe, or frame index of the target sequence.

[0154] As an example, the target sequence initial seed C can be generated according to the following formula:

[0155]

[0156] Where l is the number of the Orthogonal Frequency-Division Multiplexing (OFDM) symbol, is the number of symbols in a time slot, It is the timeslot number within the radio frame.

[0157] In this embodiment 2-1, when generating the initial seed of the target sequence, a time parameter is introduced to increase the time-varying property of the target sequence, making it difficult to be tracked and deciphered, and the interference is randomized, thereby reducing security risks.

[0158] Embodiment 2-2: The target sequence initial seed is generated based on target channel information, time parameters and configuration parameters.

[0159] In some embodiments, the transmitting end device first quantizes the channel information on N frequency domain units included in the target channel information, and further generates an initial seed of the target sequence based on the time parameter, the configuration parameter and the quantized channel information.

[0160] For example, if the channel information H(n) on the nth frequency domain unit among the channel information on N frequency domain units is expressed as:

[0161] H(n)=A(n)e jθ(n), n=0,1,2…N-1, where A(n) represents the amplitude information of the channel information on the nth frequency domain unit, and θ(n) represents the phase information of the channel information on the nth frequency domain unit. Further, the transmitting end device may quantize H(n) to obtain H′(n). For the specific quantization method, refer to the specific implementation of Example 1. Further, the transmitting end device processes H′(n), n=0,1,…N to obtain a first sequence initial seed M, for example, M=f(H′(n)), where f is a function, which may be an accumulation function, a multiplication function, or a Fourier transform function, etc., and this application does not limit this.

[0162] Furthermore, the transmitting device obtains the target sequence initial seed according to the formula C = g(M, T, P), where g is a sequence generation function, such as accumulation, multiplication, modulo, or Fourier transform. T is a time parameter, such as the symbol, time slot, subframe, or frame index of the target sequence. P is a configuration parameter.

[0163] As an example, the target sequence initial seed C can be generated according to the following formula:

[0164]

[0165] Where l is the number of OFDM symbols, is the number of symbols in a time slot, is the timeslot number within the radio frame, and P is a configuration parameter.

[0166] In Example 2-2, when generating the initial seed of the target sequence, a time parameter is introduced to increase the time-varying nature of the target sequence, making it less susceptible to tracking and deciphering. Interference is also randomized, reducing security risks. By introducing configuration parameters configured by network devices, network devices can control the allocation of sequence resources, facilitating interference coordination or elimination.

[0167] Embodiment 2-3: The target sequence initial seed is generated based on target channel information, time parameters and predefined parameters.

[0168] In some embodiments, the transmitting end device first quantizes the channel information on N frequency domain units included in the target channel information, and further generates an initial seed of the target sequence based on the time parameter, the predefined parameter and the quantized channel information.

[0169] For example, if the channel information H(n) on the nth frequency domain unit among the channel information on N frequency domain units is expressed as:

[0170] H(n)=A(n)e jθ(n), n=0,1,2…N-1, where A(n) represents the amplitude information of the channel information on the nth frequency domain unit, and θ(n) represents the phase information of the channel information on the nth frequency domain unit. The transmitting end device can quantize H(n) to obtain H′(n). For the specific quantization method, refer to the specific implementation of Example 1. Further, the transmitting end device processes H′(n), n=0,1,…N to obtain the first sequence initial seed M, for example, M=f(H′(n)), where f is a function, which can be an accumulation function, a multiplication function, or a Fourier transform function, etc., and this application does not limit this.

[0171] Furthermore, the transmitting device obtains the target sequence initial seed according to the formula C = g(M, T, Y), where g is a sequence generation function, such as accumulation, multiplication, modulo, or Fourier transform. T is a time parameter, such as the symbol, time slot, subframe, or frame index of the target sequence. Y is a predefined parameter.

[0172] As an example, the target sequence initial seed C can be generated according to the following formula:

[0173]

[0174] Where l is the number of OFDM symbols, is the number of symbols in a time slot, is the timeslot number within the radio frame, and Y is a predefined parameter.

[0175] In some embodiments of the present application, the method 200 further includes:

[0176] The sending end device generates a target sequence according to the target sequence initial seed;

[0177] The transmitting device sends the target sequence to the receiving device.

[0178] In some embodiments of the present application, the target sequence may be a scrambling code sequence, or may be a reference signal sequence, which is not limited in the present application.

[0179] As an example, the target sequence may be a demodulation reference signal (DMRS) sequence, a channel state information reference signal (CSI-RS) sequence, or the like.

[0180] In summary, in the embodiments of the present application, the transmitting device or the receiving device can generate the target sequence initial seed based on the target channel information corresponding to the link between the two. Since the target channel information is a dedicated parameter between the two and cannot be known by other devices, the target sequence initial seed determined based on the target channel information is extremely secure, which helps reduce the security risks of information leakage.

[0181] Furthermore, the transmitting or receiving device can also generate the target sequence initial seed based on the target channel information, combined with other parameters such as time parameters and configuration parameters. The introduction of time parameters increases the time-variability of the target sequence, making it less susceptible to tracking and deciphering, and randomizes interference, reducing security risks. The introduction of configuration parameters configured by network devices allows them to control the allocation of sequence resources, facilitating interference coordination or elimination.
