Currently, uniform perception signals are commonly used for perception measurements, where evenly spaced time-frequency resources are allocated for transmitting the perception signals.

[0061] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0062] 1. Integrated Sensing And Communication (ISAC), also known as ISAC for short.

[0063] Future B5G and 6G wireless communication systems are expected to provide a variety of high-precision sensing services, such as indoor positioning for robot navigation, Wi-Fi sensing for smart homes, and radar sensing for autonomous vehicles. Sensing and communication systems are typically designed separately and occupy different frequency bands. ISAC enables sensing and communication systems to share the same frequency band and hardware, improving frequency efficiency and reducing hardware costs. ISAC will become a key technology in future wireless communication systems, supporting many important application scenarios. Typical applications of ISAC include navigation and obstacle avoidance for autonomous vehicles, indoor positioning and activity recognition based on Wi-Fi, communication and sensing for unmanned aerial vehicles, extended reality (XR), and integrated radar and communication. Each application has different requirements, limitations, and regulatory issues. ISAC has attracted significant research interest and attention from both academia and industry.

[0064] ISAC achieves low-cost, integrated communication and perception capabilities through shared hardware and software-defined functions. Its key features include: a unified and simplified architecture; reconfigurable and scalable functions; and improved efficiency and reduced costs. The advantages of integrated communication and perception are threefold: reduced equipment cost and size; improved spectrum utilization; and enhanced system performance.

[0065] According to the difference between the sending node and the receiving node of the sensing signal, there are 6 basic sensing methods, such as Figure 2 As shown, specifically including:

[0066] (1) Base station self-transmitting and self-receiving sensing: In this sensing mode, base station A sends a sensing signal and performs sensing measurement by receiving the echo of the sensing signal.

[0067] (2) Inter-base station air interface sensing: Base station B receives the sensing signal sent by base station A and performs sensing measurements.

[0068] (3) Uplink air interface perception: Base station A receives the perception signal sent by terminal A and performs perception measurement.

[0069] (4) Downlink air interface perception: Terminal B receives the perception signal sent by base station B and performs perception measurement.

[0070] (5) Terminal self-transmitting and self-receiving perception: Terminal A sends a perception signal and performs perception measurement by receiving the echo of the perception signal.

[0071] (6) Sidelink perception between terminals: Terminal B receives the perception signal sent by terminal A and performs perception measurements.

[0072] It should be noted that Figure 2Each perception method in the text takes a perception signal sending node and a perception signal receiving node as an example. In actual systems, one or more different perception methods can be selected according to different perception use cases and perception requirements, and each perception method can have one or more sending nodes and receiving nodes. Figure 2 The perception targets in the example are people and cars, and it is assumed that neither people nor cars carry or install signal transmission equipment. The perception targets in actual scenes will be richer.

[0073] 2. Limitations of uniform perception signals.

[0074] The time-frequency resource configuration parameters of the uniform perception signal include: the number of subcarriers occupied by the perception signal, the number of orthogonal frequency division multiplex (OFDM), the perception subcarrier index interval, and the perception OFDM symbol index interval. Among them, the perception subcarrier index interval or the perception OFDM symbol index interval is the interval between the indices of adjacent subcarriers or adjacent OFDM symbols occupied by the perception signal; for example, the index of the subcarrier occupied by the perception signal is {0,3,6,9,12,15···}, then the subcarrier index interval is 3. The signal configuration and corresponding signal processing of the uniform perception signal are relatively simple, and have good perception performance. However, in the scenario of synaesthesia integration, the uniform perception signal has the following challenges:

[0075] Large resource overhead: In order to meet the requirements of delay resolution and Doppler resolution, the perception signal usually needs to occupy a large bandwidth in the frequency domain and a long duration in the time domain. For example, in order to meet the measurement of typical perception targets such as pedestrians and vehicles, the perception signal bandwidth needs to be above 100 MHz and the CPI usually needs to be in the range of 10 ms to 100 ms. At the same time, in order to meet the requirements of maximum unambiguous delay and maximum unambiguous Doppler, the subcarrier index interval δ occupied by the perception signal is f and OFDM symbol index interval δ t It needs to be less than a certain value, that is, the perception signal meets the Nyquist sampling condition in the frequency domain and time domain. Therefore, the number of subcarriers and OFDM symbols occupied by the perception signal is large. Furthermore, in the multi-port scenario, the number of resource elements (REs) occupied by the perception signal increases linearly with the number of ports, such as Figure 3 shown.

[0076] Signal configuration is difficult to coordinate: To achieve high-resolution perception, the time-frequency resources of the perception signal span a large range, and evenly sampled perception signals require periodic signal resources. In the scenario of integrated interawareness, a variety of communication services (including low-latency, high-reliability services) and perception services coexist, and correspondingly, various signals and channels are dedicated. It is difficult to ensure that signal resources with a specific recurring period are allocated to a specific perception signal.

[0077] Difficult to combine with the current NR reference signal: In the scenario of synaesthesia integration, if the current NR reference signal can be fully utilized, it will greatly reduce the resource overhead of perception and accelerate the implementation of perception functions. However, the various reference signals of existing NR are designed according to the needs of communication services, such as Figure 4 As shown, the distribution is usually non-uniform over a larger time span, which makes it impossible to achieve a uniformly sampled perceptual signal configuration.

[0078] In sensing applications, the sensing targets are often sparse in the delay and Doppler domains. Therefore, the recovered signal can be reconstructed from sampling points below the Nyquist sampling rate. In other words, non-uniform signals can be used to perform sensing services, thus overcoming the aforementioned challenges of uniform sensing signals. To this end, embodiments of the present application provide a sensing signal configuration method to enable the transmission of non-uniform sensing signals.

[0079] The following describes in detail the perception signal configuration method provided in the embodiments of the present application through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0080] Reference Figure 5 , the embodiment of the present application provides a method for configuring a sensing signal, such as Figure 5 As shown, the perception signal configuration method includes:

[0081] Step 501: A first device obtains first configuration information, where the first configuration information is used to indicate a first resource set, and the first resource set is used for transmission of a sensing signal.

[0082] The first configuration information includes second configuration information and at least one sequence indication information;

[0083] The second configuration information is used to indicate a second resource set;

[0084] The at least one sequence indication information is used to determine the first resource set from the second resource set, and the first resource set includes non-uniformly distributed time-frequency resources.

[0085] In this embodiment of the present application, after the first device obtains the first configuration information, it can perform a target operation based on the first configuration information. The target operation includes at least one of the following: sending a perception signal; receiving a perception signal; or processing a perception signal. In other words, in this embodiment of the present application, the first configuration information has at least one of the following functions:

[0086] used to instruct the first device to send a perception signal;

[0087] used to instruct the first device to receive a perception signal;

[0088] Used to instruct the first device to perform signal processing on the perception signal.

[0089] Optionally, the above-mentioned first configuration information can be configured through a first information element (IE); or, the first configuration information can be configured through a first Config in a first IE; or, the first configuration information can be configured through a first signaling.

[0090] Optionally, in some embodiments, the second configuration information and the at least one sequence indication information can be configured through one IE; or, the second configuration information and the at least one sequence indication information can also be configured through one Config in one IE; or, the second configuration information can be configured through one config in one IE, and the at least one sequence indication information can be configured through another config in one IE or at least one other config; or, the second configuration information and the at least one sequence indication information can be configured in different IEs configured in the same signaling (e.g., RRC).

[0091] Optionally, in some embodiments, the perception signal may be used to perform a perception service or a synaesthesia-integrated service. The perception signal may be a perception-specific signal, a synaesthesia-integrated signal, or a communication signal, etc., which is not further limited herein. For example, in some embodiments, the perception signal may include at least one of the following:

[0092] Dedicated perception signals, such as perception signals generated based on linear frequency modulation chirp or frequency modulated continuous wave (FMCW) signals, or perception signals generated based on pseudo-noise (PN) sequences, ZC (Zadoff Chu) sequences, or other constant envelope zero auto-correlation (CAZAC) sequences;

[0093] Reference signals, such as Demodulation Reference Signal (DMRS), Channel State Information Reference Signal (CSI-RS), Sounding Reference Signal (SRS), and Positioning Reference Signal (PRS);

[0094] Synchronisation signals, such as Primary Synchronisation Signal (PSS) and Secondary Synchronisation Signal (SSS);

[0095] Signals that carry communication data, such as the Physical Downlink Shared Channel (PDSCH) signal, the Physical Uplink Shared Channel (PUSCH) signal, or the Physical Downlink Control Channel (PDCCH) signal, the Physical Uplink Control Channel (PUCCH) signal, etc.

[0096] It should be understood that, since the above-mentioned perception signal is transmitted on non-uniformly distributed time-frequency resources, the perception signal can be called a non-uniform perception signal.

[0097] Optionally, the at least one sequence indication information is used to determine the first resource set from the second resource set, which can be understood as:

[0098] In a case where the first configuration information includes sequence indication information, the sequence indication information is used to determine a first resource set of a single-port signal;

[0099] When the first configuration information includes at least two sequence indication information, the at least two sequence indication information are used to determine a first resource set of a multi-port signal. The multi-port first resource set may include multiple resource subsets, and each resource subset corresponds to the sequence indication information one-to-one.

[0100] Optionally, the first resource set including non-uniformly distributed time-frequency resources can be understood as the first resource set including at least one of the following: non-uniformly distributed time domain resources; non-uniformly distributed frequency domain resources. The time domain resources are composed of time domain resource units. For example, for an OFDM waveform, the time domain resource unit is an OFDM symbol; for a pulse waveform (FMCW pulse, ultra-wideband (UWB) pulse, etc.), the time domain resource unit is a pulse. The frequency domain resources are composed of frequency domain resource units. For example, for an OFDM waveform, the frequency domain resource unit is a subcarrier.

[0101] In an embodiment of the present application, first configuration information is obtained by a first device, where the first configuration information indicates a first resource set used for transmitting a perception signal. The first configuration information includes second configuration information and at least one sequence indication information. The second configuration information indicates a second resource set. The at least one sequence indication information is used to determine the first resource set from the second resource set, and the first resource set includes non-uniformly distributed time-frequency resources. This clarifies the configuration of resources for the non-uniform perception signal, thereby enabling the transmission of the non-uniform perception signal.

[0102] Optionally, in some embodiments, the second resource set includes any one of the following: a group of uniformly distributed time domain resources; a group of uniformly distributed frequency domain resources; a group of uniformly distributed time-frequency domain two-dimensional resources.

[0103] Optionally, in one case, the second configuration information can be used to indicate a group of uniformly distributed time domain resources. For example, the time domain resource units in a group of time domain resource units indicated by the second configuration information can be understood as target time domain resource units, and the interval between any two target time domain resource units is Δm time domain resource units.

[0104] Optionally, in one case, the second configuration information can be used to indicate a group of uniformly distributed frequency domain resources. For example, the frequency domain resource units in a group of frequency domain resource units indicated by the second configuration information can be understood as target frequency domain resource units, and the interval between any two target frequency domain resource units is Δn frequency domain resource units.

[0105] Optionally, in one case, the second configuration information can be used to indicate a group of uniformly distributed time-frequency domain two-dimensional resources. For example, the time domain resource units in the group of time-frequency domain resource units indicated by the second configuration information can be understood as target time-frequency domain resource units, and the frequency domain resource units can be understood as target frequency domain resource units. That is, the group of time-frequency domain resource units indicated by the second configuration information includes m target time domain resource units in the time domain and n target frequency domain resource units in the frequency domain. In other words, the group of time-frequency domain resource units indicated by the second configuration information includes m×n resource elements (RE), and the interval between any two adjacent target time domain resource units is Δm time domain resource units, and the interval between any two adjacent target frequency domain resource units is Δn frequency domain resource units, where Δm and Δn are non-negative integers.

[0106] Optionally, in some embodiments, the sequence indication information is used to indicate a non-uniform sequence.

[0107] Optionally, the association relationship between the non-uniform sequence and the second resource set may be agreed upon by a protocol or indicated by a second device, that is, in some embodiments, the sequence indication information is also used to indicate the association relationship between the non-uniform sequence and the second resource set.

[0108] It should be noted that the indication information indicating the non-uniform sequence and the indication information indicating the association relationship between the non-uniform sequence and the second resource set may be carried in the same signaling or different signaling, which is not further limited here.

[0109] In this embodiment of the present application, the non-uniform sequence can be used to determine the first resource set, where each sequence indication information is used to indicate one or two non-uniform sequences. When one sequence indication information is used to indicate one non-uniform sequence, the non-uniform sequence is associated with at least one of a time domain resource and a frequency domain resource. When one sequence indication information is used to indicate two non-uniform sequences, one non-uniform sequence is associated with a time domain resource, and the other non-uniform sequence is associated with a frequency domain resource.

[0110] Optionally, in some embodiments, the sequence indication information satisfies at least one of the following:

[0111] In a case where the second resource set includes a group of uniformly distributed time domain resources, the sequence indication information is used to indicate a non-uniform sequence, and the non-uniform sequence is associated with the group of uniformly distributed time domain resources;

[0112] In a case where the second resource set includes a group of uniformly distributed frequency domain resources, the sequence indication information is used to indicate a non-uniform sequence, and the non-uniform sequence is associated with the group of uniformly distributed frequency domain resources;

[0113] In a case where the second resource set includes a set of uniformly distributed two-dimensional time-frequency domain resources, the sequence indication information is used to indicate a non-uniform sequence, and the non-uniform sequence is associated with at least one of a time domain resource and a frequency domain resource in the two-dimensional time-frequency domain resources;

[0114] In the case where the second resource set includes a group of uniformly distributed time-frequency domain two-dimensional resources, the sequence indication information is used to indicate two non-uniform sequences, wherein one non-uniform sequence is associated with the time domain resources in the group of uniformly distributed time-frequency domain two-dimensional resources, and the other non-uniform sequence is associated with the frequency domain resources in the group of uniformly distributed time-frequency domain two-dimensional resources.

[0115] In an embodiment of the present application, when the second resource set includes a group of uniformly distributed time domain resources or time domain resources, the sequence indication information indicates a non-uniform sequence, and the non-uniform sequence is associated with the time domain resources or frequency domain resources included in the second resource set by default, then the sequence indication information may not include indication information of the association relationship between the non-uniform sequence and the second resource set.

[0116] Optionally, when the second resource set includes a group of uniformly distributed two-dimensional time-frequency domain resources and the sequence indication information indicates a non-uniform sequence, the sequence indication information also needs to include indication information of the association relationship between the non-uniform sequence and the second resource set. For example, in some embodiments, 1-bit indication information can be used. For example, when the setting value is 1, it indicates that the non-uniform sequence is associated with the time domain resources in the second resource set; when the value is 0, it indicates that the non-uniform sequence is associated with the frequency domain resources in the second resource set; 2-bit indication information can also be used. For example, when the setting value is 01, it indicates that the non-uniform sequence is associated with the time domain resources in the second resource set; when the value is 10, it indicates that the non-uniform sequence is associated with the frequency domain resources in the second resource set; when the value is 11, it indicates that the non-uniform sequence is associated with both the time domain resources and the frequency domain resources in the second resource set.

[0117] Optionally, when the second resource set includes a group of uniformly distributed two-dimensional time-frequency domain resources and the sequence indication information indicates two non-uniform sequences, the sequence indication information may include indication information of the association relationship between the non-uniform sequence and the second resource set. For example, in some embodiments, 1-bit indication information may be used. When the value is set to 1, it indicates that the first non-uniform sequence is associated with the time domain resources in the second resource set, and the second non-uniform sequence is associated with the frequency domain resources in the second resource set. When the value is 0, it indicates that the first non-uniform sequence is associated with the frequency domain resources in the second resource set, and the second non-uniform sequence is associated with the time domain resources in the second resource set.

[0118] Optionally, when the second resource set includes a set of uniformly distributed two-dimensional time-frequency domain resources and the sequence indication information indicates two non-uniform sequences, the sequence indication information may not include information indicating the association relationship between the non-uniform sequence and the second resource set, and the association relationship between the two non-uniform sequences and the time-frequency domain resources of the second resource set is agreed upon by protocol. For example, the first non-uniform sequence of the two non-uniform sequences indicated by the sequence indication information is associated with the time domain resources in the second resource set, and the second non-uniform sequence is associated with the frequency domain resources in the second resource set. Alternatively, the first non-uniform sequence of the two non-uniform sequences indicated by the sequence indication information is associated with the frequency domain resources in the second resource set, and the second non-uniform sequence is associated with the time domain resources in the second resource set.

[0119] Optionally, in some embodiments, the type of the non-uniform sequence includes any one of the following: a bitmap sequence and a position index sequence.

[0120] In an embodiment of the present application, for a bitmap sequence, a value of a certain element in the sequence can be set to 1 to indicate that the corresponding time-domain resource unit (i.e., the target time-domain resource unit) or frequency-domain resource unit (i.e., the frequency-domain time-domain resource unit) in the second resource set is allocated to the perception signal, and a value of 0 indicates that the corresponding time-domain resource unit or frequency-domain resource unit in the second resource set is not allocated to the perception signal. For example, if the non-uniform sequence is '1000110101' and the associated second resource set includes 10 uniformly distributed frequency-domain resource units, then the first, fifth, sixth, eighth, and tenth (counting starting from 1) frequency-domain resource units are frequency-domain resource units allocated to the perception signal.

[0121] Of course, in some embodiments, the value of an element in the sequence can also be set to 0 to indicate that the corresponding time domain resource unit or frequency domain resource unit in the second resource set is allocated to the perception signal, and the value can be set to 1 to indicate that the corresponding time domain resource unit or frequency domain resource unit in the second resource set is not allocated to the perception signal.

[0122] Optionally, for the position index sequence, the position index of the time domain resource unit or frequency domain resource unit allocated to the perception signal is directly given in the sequence. For example, if the non-uniform sequence is {1, 5, 6, 8, 10}, the associated second resource set includes 10 uniformly distributed frequency domain resource units, indicating that the 1st, 5th, 6th, 8th, and 10th (counting starting from 1) frequency domain resource units are frequency domain resource units allocated to the perception signal.

[0123] Optionally, in some embodiments, the bitmap sequence includes a random bitmap sequence, or the position index sequence includes at least one of a random position index sequence, a nested array sequence, and a coprime array sequence.

[0124] In the embodiment of the present application, the non-uniform sequence can be a random sequence or a non-random sequence, wherein the random bitmap sequence and the random position index sequence can be understood as random sequences, and the above-mentioned nested array sequence and coprime array sequence can be understood as non-random sequences.

[0125] Optionally, when the non-uniform sequence is a random sequence, the non-uniform sequence can be generated by a specific random function according to given parameters. In this case, the random sequence can be in the form of: a bitmap sequence (i.e., a random bitmap sequence) or a position index sequence (i.e., a random position index sequence).

[0126] The random bitmap sequence may include a random Bernoulli sequence, or a random binomial distribution sequence. Based on given parameters, the generator function of the random Bernoulli sequence can directly generate a 0 or 1 sequence that meets the preset requirements. The parameters include:

[0127] Sequence length: the sum of the number of '1's and '0's in the non-uniform sequence; in some embodiments, the sequence length parameter may be defaulted. In this case, the sequence length defaults to the number of time-domain resource units in the time-domain resources or the number of frequency-domain resource units in the frequency-domain resources included in the associated second resource set. For example, if the frequency-domain resources in the second resource set are 10 uniformly distributed frequency-domain resource units, the sequence length may default to 10;

[0128] Sequence weight: the number or proportion of '1's in the sequence, that is, the number of time-domain resource units or frequency-domain resource units actually occupied by the non-uniform sensing signal in the time-frequency domain resources included in the second resource set, which is equal to the number of '1's in the sequence; or, the ratio of the number of time-domain resource units or frequency-domain resource units actually occupied by the non-uniform sensing signal in the time-frequency domain resources included in the second resource set to the corresponding sequence length, which is equal to the ratio of the number of '1's in the sequence to the sequence length.

[0129] Random seed: serves as the initial condition for the generator function of the random Bernoulli sequence.

[0130] For the random position index sequence, a random selection sequence can be included, where M non-repeating integers are randomly selected from integers 1 to N, where M < N. Its parameters include:

[0131] Maximum integer: This is the N mentioned above. In some embodiments, the maximum integer parameter may be omitted. In this case, the maximum integer defaults to the number of time-domain resource units in the time-domain resources or the number of frequency-domain resource units in the frequency-domain resources included in the associated second resource set. For example, if the frequency-domain resources included in the second resource set are 10 evenly distributed frequency-domain resource units, the maximum integer may default to 10.

[0132] Sequence length: i.e., the aforementioned M, which is the number of time-domain resource units or frequency-domain resource units actually occupied by the non-uniform sensing signal in the time-frequency domain resources included in the second resource set, i.e., equal to M;

[0133] Random seed: The initial condition used by the generator function to select a sequence of random numbers.

[0134] Optionally, when the non-uniform sequence is a non-random sequence, the non-uniform sequence can be generated according to given parameters and specific rules. The non-random sequence can be in the form of a position index sequence (i.e., a random position index sequence). Specifically, it can be a nested array sequence or a coprime array sequence.

[0135] For nested array sequences: a non-uniform sequence can be composed of at least two uniform sequences, wherein the interval between adjacent elements in the first uniform sequence is δ and the number of elements is M1; the interval between adjacent elements in the second uniform sequence is M1*δ and the number of elements is M2; the interval between adjacent elements in the third uniform sequence is M1*M2*δ and the number of elements is M3; the interval between adjacent elements in the Lth uniform sequence is M1*M2*······*M L-1 *δ, the number of elements is M L , L is an integer greater than 2. For example, consider two sequences. A non-uniform sequence consists of two uniform sequences. In the first uniform sequence, the interval between adjacent elements is δ, and the number of elements in the first uniform sequence is M1. In the second uniform sequence, the interval between adjacent elements is M1*δ, and the number of elements in the second uniform sequence is M2. Furthermore, the first elements of the two uniform sequences are the same. δ is a non-negative integer, and M1 and M2 are positive integers.

[0136] For example, the first uniform sequence is {1, 2, 3, 4, 5}, then δ = 1, M1 = 5, and the second uniform sequence is {1, 6, 11, 16}, where M2 = 4. Therefore, the non-uniform sequence is the union of the above two uniform sequences {1, 2, 3, 4, 5, 6, 11, 16}.

[0137] Obviously, the number of elements in the non-uniform sequence is M1+M2-1, that is, in the time-frequency domain resources included in the second resource set, the number of time-domain resource units or frequency-domain resource units actually occupied by the non-uniform perception signal is equal to M1+M2-1.

[0138] Therefore, the parameters used to generate non-uniform sequences include:

[0139] The minimum interval, i.e., the non-negative integer δ mentioned above, indicates that the minimum interval of the non-uniform sequence is δ times the interval between time domain resource units in the time domain resources included in the associated second resource set or the interval between frequency domain resource units in the frequency domain resources; in some embodiments, the minimum interval parameter may be defaulted, in which case the minimum interval is defaulted to be equal to the interval between time domain resource units in the time domain resources included in the associated second resource set or the interval between frequency domain resource units in the frequency domain resources. For example, if the frequency domain resources included in the second resource set are 10 uniformly distributed frequency domain resource units, and the interval between any two adjacent frequency domain resource units in these 10 frequency domain resource units is 3 frequency domain resource units, then the minimum interval may be defaulted to 3;

[0140] At least one first value (for example, may include the positive integer M1 and the positive integer M2).

[0141] For coprime matrix sequences: a non-uniform sequence can be composed of at least two uniform sequences, the interval between any two adjacent elements in each uniform sequence is the same, and the intervals between adjacent elements corresponding to any two uniform sequences are prime numbers to each other. For example, in some embodiments, when the non-uniform sequence is composed of three uniform sequences, the interval between adjacent elements in the first uniform sequence is M1*δ, the interval between adjacent elements in the second uniform sequence is M2*δ, and the interval between adjacent elements in the third uniform sequence is M3*δ, where any two of M1, M2, and M3 are prime numbers to each other.

[0142] For example, in some embodiments, for coprime matrix sequences, when a non-uniform sequence is composed of two uniform sequences, the interval between adjacent elements in the first uniform sequence is M1*δ, and the number of elements in the first uniform sequence is M2; the interval between adjacent elements in the second uniform sequence is M2*δ, and the number of elements in the second uniform sequence is M1; and M1 and M2 are mutually prime, and the first elements of the two uniform sequences are the same. Here, δ is a non-negative integer, and M1 and M2 are positive integers. For example, if the first uniform sequence is {1, 4, 7, 10, 13}, where δ = 1, M2 = 5, and M1 = 3, then the second uniform sequence is {1, 6, 11}. Therefore, the non-uniform sequence is the union of the two uniform sequences, {1, 4, 6, 7, 10, 11, 13}.

[0143] Obviously, the number of elements in the non-uniform sequence is M1+M2-1, that is, in the time-frequency domain resources included in the second resource set, the number of time-domain resource units or frequency-domain resource units actually occupied by the non-uniform perception signal is equal to M1+M2-1.

[0144] Therefore, the parameters used to generate non-uniform sequences include:

[0145] The minimum interval, i.e., the non-negative integer δ mentioned above, indicates that the minimum interval of the non-uniform sequence is δ times the interval between time domain resource units in the time domain resources included in the associated second resource set or the interval between frequency domain resource units in the frequency domain resources; in some embodiments, the minimum interval parameter may be defaulted, in which case the minimum interval is defaulted to be equal to the interval between time domain resource units in the time domain resources included in the associated second resource set or the interval between frequency domain resource units in the frequency domain resources. For example, if the frequency domain resources included in the second resource set are 10 uniformly distributed frequency domain resource units, and the interval between any two adjacent frequency domain resource units in these 10 frequency domain resource units is 3 frequency domain resource units, then the minimum interval may be defaulted to 3;

[0146] At least two second values ​​(for example, may include the positive integer M1 and the positive integer M2 mentioned above).

[0147] Optionally, in some embodiments, the sequence indication information includes at least one of the following: a sequence type of the non-uniform sequence and a sequence parameter used to determine the non-uniform sequence.

[0148] Optionally, in some embodiments, the sequence indication information satisfies at least one of the following:

[0149] In the case where the sequence type of the non-uniform sequence is a random bitmap sequence, the sequence parameters of the non-uniform sequence include at least one of a sequence length, a sequence weight, and a random seed:

[0150] In a case where the sequence type of the non-uniform sequence is a random position index sequence, the sequence parameters of the non-uniform sequence include at least one of a maximum integer, a sequence length, and a random seed;

[0151] When the sequence type of the non-uniform sequence is a nested array sequence, the sequence parameter of the non-uniform sequence includes at least one of a minimum resource interval and first information, the first information includes at least one first value, each first value is used to represent the number of elements in a uniform sequence in the nested array sequence;

[0152] When the sequence type of the non-uniform sequence is a coprime matrix sequence, the sequence parameters of the non-uniform sequence include at least one of a minimum resource interval and second information, the second information includes at least two second values, and each second value is used to represent the number of elements in a uniform sequence in the coprime matrix sequence.

[0153] In the embodiments of the present application, the number of the first values ​​can be one or more. For example, when the number of the first values ​​is one, it can be understood that the number of elements in each uniform sequence in the nested array sequence is the same. When the number of the first values ​​is at least two, it can be assumed that the first values ​​correspond to the uniform sequences in the nested array sequence. For example, when the nested array sequence includes two uniform sequences, the two first values ​​correspond to M1 and M2 in the example of the nested array sequence.

[0154] Optionally, there may be two or more second values, wherein the second values ​​correspond one-to-one to the uniform sequences in the coprime matrix sequence. For example, when the coprime matrix sequence includes two uniform sequences, the two second values ​​correspond to M1 and M2 in the example of the coprime matrix sequence, respectively.

[0155] Optionally, in some embodiments, the sequence type may be agreed upon by protocol to be one of the above four types (random bitmap sequence, random position index sequence, nested array sequence, and coprime array sequence), and there is no need to indicate the sequence type.

[0156] Optionally, in some embodiments, the sequence indication information includes non-uniform sequence identification information.

[0157] Optionally, the above-mentioned non-uniform sequence identification information may include but is not limited to an identification (ID) of the non-uniform sequence.

[0158] Optionally, in some embodiments, the method further comprises:

[0159] The first device determines the non-uniform sequence based on the non-uniform sequence identification information and a non-uniform sequence list, wherein the non-uniform sequence list includes any one of the following:

[0160] At least two non-uniform sequences and non-uniform sequence identification information corresponding to each non-uniform sequence;

[0161] At least two pieces of target information and non-uniform sequence identification information corresponding to each piece of target information, wherein the target information includes at least one of a sequence type of the non-uniform sequence and a sequence parameter used to determine the non-uniform sequence.

[0162] In an embodiment of the present application, a non-uniform sequence list can be pre-configured. The non-uniform sequence list includes indication information for determining multiple non-uniform sequences and non-uniform sequence identification information uniquely corresponding to the non-uniform sequence. The second device can indicate the non-uniform sequence used by the first device through the non-uniform sequence identification information.

[0163] Optionally, the non-uniform sequence list includes at least two non-uniform sequences and non-uniform sequence identification information corresponding to each non-uniform sequence. An example is shown in Table 1 below.

[0164] Table 1:

[0165] ID=1 ‘1000110101’ ID=2 ‘0111001010’ ID=3 {1,2,3,4,5,6,11,16} ID=4 {1,4,6,7,10,11,13} …… ……

[0166] Optionally, the non-uniform sequence list includes at least two pieces of target information and non-uniform sequence identification information corresponding to each piece of target information. An example is shown in Table 2 below.

[0167] Table 2

[0168] ID=1 Sequence type: random bitmap sequence, sequence length: 100, sequence weight: 50, random seed: 1 ID=2 Sequence type: Random position index sequence, Maximum integer: 100, Sequence length: 50, Random seed: 2 ID=3 <![CDATA[Sequence type: nested array sequence, minimum spacing: 1, positive integer M1: 4, positive integer M2: 8]]> ID=4 Sequence type: coprime matrix sequence, minimum interval: 2, positive integer M1: 5, positive integer M2: 7 …… ……

[0169] Optionally, in some embodiments, at least one of the sequence length, the maximum integer, the positive integer M1, and the positive integer M2 in the target information may be omitted. In this case, an example corresponding to Table 2 is shown in Table 3.

[0170] Table 3:

[0172] Optionally, in some embodiments, the sequence type in the target information may be further omitted. In this case, an example corresponding to Table 2 and Table 3 is shown in Table 4.

[0173] Table 4:

[0174] ID=1 Sequence weight: 80, random seed: 1 ID=2 Sequence weight: 60, random seed: 2 ID=3 Sequence weight: 40, random seed: 3 ID=4 Sequence weight: 20, random seed: 4 …… ……

[0175] Optionally, in some embodiments, the first configuration information further includes a power enhancement indication, and the power enhancement indication is used to determine the power of the perception signal.

[0176] In the embodiment of the present application, the function enhancement indication may be used to indicate whether to perform power enhancement or the ratio of function enhancement. That is, in some embodiments, the power enhancement indication includes first indication information or second indication information;

[0177] The first indication information is used to indicate whether the sensing signal is to be power-enhanced;

[0178] The second indication information is used to indicate a power boost ratio of the perception signal.

[0179] It should be understood that, assuming that the number of time-domain resource units or frequency-domain resource units in the time-frequency resources included in the second resource set is N, the associated non-uniform sequence is used to determine M of the N time-domain resource units or frequency-domain resource units allocated to the perception signal, where M < N. Obviously, the remaining NM time-domain resource units or frequency-domain resource units are not allocated to the perception signal, which will cause a loss of perception signal power at the receiving end. In order not to reduce the perception signal power received by the receiving end, the power of the remaining NM time-domain resource units or frequency-domain resource units can be borrowed to the M time-domain resource units or frequency-domain resource units allocated to the perception signal. That is, the power of the non-uniform perception signal is enhanced. In this case, the power is further enhanced based on the power indicated in the second configuration information.

[0180] Optionally, the power boost indication may be understood as indicating whether to lend the power of the time domain resource units or frequency domain resource units not allocated to the perception signal in the time domain resource units or frequency domain resource units included in the second resource set to the time domain resource units or frequency domain resource units allocated to the perception signal. In this case, the power boost indication may be represented by one bit:

[0181] For example, if the power boost indicator is '0', it means that the power of the time domain resource units or frequency domain resource units included in the second resource set that are not allocated to the perception signal will not be borrowed to the time domain resource units or frequency domain resource units allocated to the perception signal, that is, the perception signal will not be power boosted; in this case, the power of each time domain resource unit or frequency domain resource unit in the non-uniform perception signal (denoted as P2) is the same as the power of the corresponding time domain resource unit or frequency domain resource unit in the time-frequency domain resources included in the second resource set (denoted as: P1), that is, P2 = P1.

[0182] For example, if the power boost indicator is '1', it means that the power of the time-domain resource units or frequency-domain resource units included in the second resource set that are not allocated to the perception signal is borrowed to the time-domain resource units or frequency-domain resource units allocated to the perception signal, that is, the perception signal is power-boosted. In this case, the power of each time-domain resource unit or frequency-domain resource unit in the non-uniform perception signal (denoted as P2) is boosted based on the power of the corresponding time-domain resource unit or frequency-domain resource unit in the time-frequency domain resources included in the second resource set (denoted as P1), and P2 = (N / M) × P1.

[0183] Optionally, the power boost indication may be understood as indicating whether to lend part or all of the power of the time domain resource units or frequency domain resource units included in the second resource set that are not allocated to the perception signal to the time domain resource units or frequency domain resource units allocated to the perception signal. In this case, the power boost indication may be represented by k (k ≥ 2) bits. In this case, the following situations may occur:

[0184] For example, if all k bits of the power boost indication are '0', it means that the power of the time-domain resource units or frequency-domain resource units included in the second resource set that are not allocated to the perception signal is not borrowed from the time-domain resource units or frequency-domain resource units allocated to the perception signal, that is, the power boost ratio of the perception signal is 0. In this case, the power of each time-domain resource unit or frequency-domain resource unit in the non-uniform perception signal (denoted as P2) is the same as the power of the corresponding time-domain resource unit or frequency-domain resource unit in the time-frequency domain resources included in the second resource set (denoted as P1), that is, P2 = P1.

[0185] For example, if all k bits of the power boost indication are '1', it means that the power of the time-domain resource elements or frequency-domain resource elements in the second resource set that are not allocated to the perception signal is fully borrowed to the time-domain resource elements or frequency-domain resource elements allocated to the perception signal, i.e., the power boost ratio of the perception signal is 1. In this case, the power of each time-domain resource element or frequency-domain resource element in the non-uniform perception signal (denoted as P2) is boosted based on the power of the corresponding time-domain resource element or frequency-domain resource element in the time-frequency resources included in the second resource set (denoted as P1), and P2 = (N / M) × P1.

[0186] For example, if part of the k bits of the power enhancement indication is '0' and part is '1', it means that part of the power of the time domain resource units or frequency domain resource units included in the second resource set that is not allocated to the perception signal is borrowed to the time domain resource units or frequency domain resource units allocated to the perception signal; in this case, the power of each time domain resource unit or frequency domain resource unit in the non-uniform perception signal (denoted as P2) is enhanced according to the pre-configured power scaling factor α based on the power of the corresponding time domain resource unit or frequency domain resource unit in the time-frequency domain resources included in the second resource set (denoted as: P1), and P2 = (1 + α × ((NM)) / M) × P1, where 0 ≤ α ≤ 1. The correspondence between the power scaling factor α and the power enhancement indication is pre-configured by signaling. Table 5 below gives an example of a power scaling factor table when the power enhancement indication includes 2 bits. The power enhancement indications of '00' and '11' correspond to the cases of no borrowing and full borrowing, respectively.

[0187] Table 5:

[0188] Power boost indication Power scaling factor ‘00’ 0 ‘01’ 0.25 ‘10’ 0.5 ‘11’ 1

[0189] Optionally, in some embodiments, the first configuration information includes a power boost indication only when the non-uniform sequence in the sequence indication information is associated with the frequency domain resources included in the second resource set.

[0190] Optionally, in some embodiments, when the first configuration information includes one sequence indication information, the second resource set is associated with the one sequence indication information, and the sensing signal is a single-port signal;

[0191] Alternatively, in a case where the first configuration information includes at least two sequence indication information, the second resource set is associated with the at least two sequence indication information, and the perception signal is a multi-port signal.

[0192] Optionally, in some embodiments, when the first configuration information includes two sequence indication information, the non-uniform sequence associated with one sequence indication information and the non-uniform sequence associated with the other sequence indication information are orthogonal to each other;

[0193] The at least two sequence indication information satisfies any one of the following:

[0194] Each non-uniform sequence indicated by the sequence indication information is associated with a time domain resource;

[0195] Each non-uniform sequence indicated by the sequence indication information is associated with a frequency domain resource;

[0196] Each non-uniform sequence indicated by the sequence indication information is associated with a two-dimensional resource in the time-frequency domain.

[0197] For example, in some embodiments, when the non-uniform sequence is a bitmap sequence, the non-uniform sequence indicated by the multiple sequence indication information has a value of '1' at any position in the sequence at most one element in the sequence at that position. For example, if two non-uniform sequences are '1000110101' and '0111001010', respectively, the two non-uniform sequences are orthogonal to each other.

[0198] It should be noted that the sequence lengths of the non-uniform sequences indicated by the multiple sequence indication information may be the same or different.

[0199] For example, in some embodiments, when the non-uniform sequence is a position index sequence, any integer between min_value and max_value appears at most once in the non-uniform sequence indicated by the plurality of sequence indication information, where min_value and max_value represent the minimum and maximum values ​​of all position index values ​​in the non-uniform sequence indicated by the plurality of sequence indication information, respectively. For example, if two non-uniform sequences are {1, 5, 6, 8, 10} and {2, 3, 4, 7, 9}, respectively, then the two non-uniform sequences are orthogonal to each other.

[0200] It should be noted that the maximum values ​​of the sequence lengths or position indexes of the non-uniform sequences indicated by the multiple sequence indication information may be the same or different.

[0201] Optionally, in some embodiments, the method for obtaining the first configuration information is determined by at least one of the following: protocol agreement and receiving from the second device;

[0202] The second device is a base station or a perception function network element.

[0203] In the embodiment of the present application, the first configuration information may be received entirely from the second device, or partially received from the second device and partially agreed upon by a protocol.

[0204] It should be noted that, when the first configuration information is received from the second device, the second configuration information and at least one sequence indication information can be carried in the same signaling or different signaling, and no further limitation is made here.

[0205] Optionally, the above-mentioned sensing function (Sensing Function) network element, which may also be called a sensing network element or a sensing network function, may be located on the RAN side or the core network side, and refers to a network node in the core network or RAN responsible for at least one function such as sensing request processing, sensing resource scheduling, sensing information interaction, and sensing data processing. It may be based on the AMF or LMF upgrade in the 5G network, or it may be other network nodes or newly defined network nodes. Specifically, the functional characteristics of the sensing function network element may include at least one of the following:

[0206] Interacting with a wireless signal transmitting device or a wireless signal measuring device (including a target terminal or a serving base station of the target terminal or a base station associated with a target area) for target information, wherein the target information includes a sensing processing request, sensing capability, sensing assistance data, a sensing measurement quantity type, sensing resource configuration information, etc., to obtain a target sensing result or a sensing measurement quantity (uplink measurement quantity or downlink measurement quantity) sent by the wireless signal measuring device; wherein the wireless signal may also be referred to as a sensing signal;

[0207] The sensing method to be used is determined based on factors such as the type of sensing service, sensing service consumer information, required sensing service quality (QoS) requirement information, sensing capabilities of the wireless signal transmitting device, and sensing capabilities of the wireless signal measuring device. The sensing method may include: base station A transmits and base station B receives, or base station transmits and terminal receives, or base station A transmits and receives by itself, or terminal transmits and base station receives by itself, or terminal transmits and receives by itself, or terminal A transmits and terminal B receives by itself, etc.;

[0208] The sensing device serving the sensing service is determined based on factors such as the type of sensing service, information about the sensing service consumer, required sensing QoS requirement information, sensing capability of the wireless signal transmitting device, and sensing capability of the wireless signal measuring device. The sensing device includes a wireless signal transmitting device or a wireless signal measuring device.

[0209] Manage the overall coordination and scheduling of resources required for sensing services, such as configuring sensing resources for base stations and / or terminals accordingly;

[0210] Data processing is performed on the values ​​of the perceived measurement quantities, or calculations are performed to obtain the perceived results.

[0211] Furthermore, the functional characteristics of the perception function network element may also include verifying perception results, estimating perception accuracy, etc.

[0212] Optionally, in some embodiments, the method further comprises:

[0213] The first device obtains third configuration information, where the third configuration information is used to indicate at least one of the following:

[0214] periodically performing transmission, reception, or signal processing of a perception signal indicated by the first configuration information;

[0215] semi-periodically performing transmission, reception, or signal processing of a perception signal indicated by the first configuration information;

[0216] The transmission, reception, or signal processing of the perception signal indicated by the first configuration information is performed aperiodically.

[0217] In the embodiments of the present application, periodically performing the transmission, reception, or signal processing of the perception signal indicated by the first configuration information can be understood or replaced by: the first device periodically performing the transmission, reception, or signal processing of the perception signal indicated by the first configuration information. Semi-periodically performing the transmission, reception, or signal processing of the perception signal indicated by the first configuration information can be understood or replaced by: upon receiving activation signaling, the first device periodically performing the transmission, reception, or signal processing of the perception signal indicated by the first configuration information. Aperiodically performing the transmission, reception, or signal processing of the perception signal indicated by the first configuration information can be understood or replaced by: upon receiving activation signaling, the first device performs the transmission, reception, or signal processing of the perception signal indicated by the first configuration information once.

[0232] Optionally, in some embodiments, the method for obtaining the third configuration information includes at least one of the following: protocol agreement and receiving from the second device;

[0238] ID of the first configuration information;

[0239] Time information: used to indicate the sending or receiving time of the sensing signal corresponding to the target measurement quantity;

[0240] The ID of the first device.

[0241] In order to better understand the present application, some examples are given below for detailed description.

[0242] Example 1: An example of a non-uniform sequence list.

[0243] Optionally, the random sequence may include a random bitmap sequence and a random position index sequence.

[0244] For random bitmap sequences: For any given set of sequence lengths and sequence weights, a computer searches for a certain range of random seeds to obtain the random seed corresponding to the sequence with the best performance.

[0245] For random position index sequences: For a given maximum integer and sequence length, a computer searches for a certain range of random seeds to obtain the random seed corresponding to the sequence with the best performance.

[0246] In the above computer search process, the indicator used to measure sequence performance is the signal-to-interference ratio. The interference here is caused by the non-periodic spectrum shift caused by the non-uniform sensing signal. The signal-to-interference ratio is calculated in the transform domain. The sequence search process is as follows:

[0247] Step 1: For a random bitmap sequence, given the sequence length N and sequence weight M, where the sequence weight represents the number of '1's in a 0 or 1 sequence; for a random position index sequence, given the maximum integer N and sequence length M.

[0248] Step 2: Set the random seed to the first value in the given range. Based on the given N and M, generate a random bitmap sequence or a random position index sequence. From this generated sequence, obtain the position index sequence of the non-uniform sequence, denoted as: B = {b_0, b_1, …, b_M}. Here, the random position index sequence is directly the position index sequence of the non-uniform sequence; the bitmap sequence must be converted to a position index sequence of the non-uniform sequence. The conversion method is to add the i-th element in the bitmap sequence to the position index sequence of the non-uniform sequence if it is '1', ultimately obtaining an index sequence B containing M elements.

[0249] Step 3: Arbitrarily set a time interval Δt, according to the formula x = e j2πBΔt Generate a signal sequence, and perform FFT operation on the signal sequence x to obtain a sequence y=FFT{x} in the transform domain.

[0250] Step 4: Detect the element with the largest amplitude or power in the sequence y, and record its amplitude or power as P max , which is the signal in the above signal-to-interference ratio.

[0251] Step 5: After removing the element with the largest amplitude or power in the sequence y, detect the element with the largest amplitude or power in the remaining sequence, and record its amplitude or power as P int Alternatively, calculate the mean of the amplitude or power in the remaining sequence, denoted by P mean .

[0252] Step 6: Calculate the signal-to-interference ratio as R=P max / P int Or R=P max / P mean .

[0253] Step 7: Repeat steps 2 to 6 to traverse the signal-to-interference ratios corresponding to all random seeds in the given range, and obtain the value of the random seed corresponding to the maximum signal-to-interference ratio, which is the random seed corresponding to the given parameters N and M.

[0254] Step 8: Traverse the values ​​of the given parameters N and M, and repeat steps 1 to 7 to obtain the random seeds corresponding to the given sets of parameters N and M.

[0255] In some embodiments, to ensure that the bandwidth or duration of the non-uniform perception signal is not reduced, it is necessary to require that the position index sequence B of the non-uniform sequence must include 1 and N. In this case, in the seventh step above, the value of the random seed corresponding to the maximum signal-to-interference ratio that meets this condition should be obtained as the random seed corresponding to the given parameters N and M.

[0256] This embodiment provides several sets of random seeds corresponding to parameters N and M obtained through computer search, where the search range for random seeds is a non-negative integer between 0 and 65535. Optionally, a schematic diagram of a random bitmap sequence obtained through computer search is shown in Table 6 below. A schematic diagram of a random position index sequence obtained through computer search is shown in Table 7 below.

[0261] Optionally, in some embodiments, a non-uniform sequence is indicated by at least one of a sequence type and a sequence parameter of the non-uniform sequence: for example, a list of non-uniform sequences with better performance obtained by computer search is stored in the second device, or stored in a network node accessible to the second device; the second device obtains a random seed from the non-uniform sequence list and sends first configuration information to the first device, the first configuration information including the random seed obtained by computer search.

[0262] Optionally, in some embodiments, a non-uniform sequence is indicated by the ID of the non-uniform sequence: a list of non-uniform sequences with better performance obtained by computer search is pre-configured to the first device, and each set of sequence parameters (including: parameters N and M, random seed) corresponds to an ID; the first configuration information sent by the second device to the first device includes an ID in the non-uniform sequence list.

[0263] In this embodiment, the sequence indication information in the first configuration information may also be: parameter N and parameter M, or only parameter M (in this case, parameter N is by default equal to the number of time domain resource units or the number of frequency domain resource units in the time and frequency domain resources included in the second resource set).

In this case, the sequence indication information in the first configuration information can indicate a non-uniform sequence using the signaling shown in Table 9.
