[0001] The present application relates to the technical field of communication, in particular to a method, apparatus, device, medium and program product for configuring sensing signal. BACKGROUND

[0002] Wireless communication and sensing are two important applications of modern radio frequency technology. Sensing uses radio waves to detect environmental parameters to achieve sensing functions such as target positioning, action recognition, and target imaging. In conventional sensing signal design, the sensing signal maintains uniform spacing in the frequency domain or the time domain.

[0003] However, the sensing performance is affected by the parameters of the sensing signal. For example, the smaller the frequency domain spacing of the sensing signal, the greater the unambiguous distance; the smaller the time domain spacing of the sensing signal, the greater the unambiguous velocity. In order to meet the sensing performance, a larger unambiguous distance and / or unambiguous velocity is required, and the frequency domain spacing and / or time domain spacing of the sensing signal needs to be smaller, thereby causing a large amount of sensing signal resource overhead.

[0063] The next generation network (for example, a 6G network) is expected to be a combination of a mobile communication network, a perception network, and a computing network. In a narrow sense, the perception network refers to a system with the capabilities of target positioning (distance measurement, speed measurement, angle measurement), target imaging, target detection, target tracking, and target recognition. In a broad sense, the perception network refers to a system with the attributes and states of all services, networks, users, terminals, and environmental objects. From the perspective of perception applications, perception can include the following categories:

[0064] · Outdoor / wide area / local area applications: including smart city (for example, weather monitoring, etc.), smart transportation / high-speed rail (for example, high-precision map construction, road supervision, intrusion detection, etc.), low-altitude application (for example, unmanned aerial vehicle monitoring and obstacle avoidance, flight intrusion detection, flight path management, etc.), and the like.

[0066] The above is only exemplary, and provides some categories of perception applications. The application range of perception is not limited to the above examples.

[0067] Wireless communication and sensing are two important applications of modern radio frequency technology. Sensing uses radio waves to detect parameters of the physical environment to achieve environmental sensing such as target positioning, action recognition, and target imaging. Traditional sensing and wireless communication exist independently, and the separate design wastes wireless spectrum and hardware resources. In the B5G and 6G era, communication spectrum moves to millimeter wave, terahertz, and visible light communication. In the future, the spectrum of wireless communication will coincide with the traditional sensing spectrum. The communication-sensing integrated technology integrates wireless communication and sensing functions, which can use wireless resources to achieve sensing functions, use widely deployed cellular networks to achieve larger range sensing services, use base stations and multiple terminals for joint sensing to achieve higher sensing accuracy, and reuse wireless communication hardware modules to achieve sensing functions and reduce costs. In summary, the communication-sensing integrated technology enables future wireless communication systems to have sensing capabilities, providing a foundation for the development of future smart transportation, smart cities, smart factories, and unmanned aerial vehicles.

[0068] FIG. 2 shows a schematic diagram of sensing modes provided by the related art, including the following eight sensing modes: (1) base station self-initiated self-reception sensing: the base station transmits a sensing signal, and the sensing target transmits a reflection signal after receiving the sensing signal; (2) terminal self-initiated self-reception sensing: the terminal transmits a sensing signal, and the sensing target transmits a reflection signal after receiving the sensing signal; (3) base station cooperative sensing: base station A transmits a sensing signal, and the sensing target transmits a reflection signal to base station B after receiving the sensing signal; (4) terminal cooperative sensing: terminal A transmits a sensing signal, and the sensing target transmits a reflection signal to terminal B after receiving the sensing signal; (5) base station-terminal cooperative sensing: the base station transmits a sensing signal, and the sensing target transmits a reflection signal to the terminal after receiving the sensing signal; (6) terminal-base station cooperative sensing: the terminal transmits a sensing signal, and the sensing target transmits a reflection signal to the base station after receiving the sensing signal; (7) sensing signal transmitting node as the sensing target: the terminal transmits a sensing signal, and the base station is the sensing target; (8) sensing signal receiving node as the sensing target: the base station transmits a sensing signal, and the terminal transmits a feedback after receiving the sensing signal, and the terminal is the sensing target.

[0069] The perception signal sending node and the perception signal receiving node can be collectively referred to as a perception node. In the above eight perception modes, there is only a single or a pair of perception nodes, and in a wireless communication system, the number of terminals (mobile phones, IoT devices, etc.) is large. When there are multiple perception nodes (i.e., base stations, mobile phones, IoT devices, etc. that can send and / or receive perception signals) around a perceived terminal, multiple perception nodes jointly participating in perception can improve the accuracy of perception and meet more complex perception service requirements to provide more abundant perception services. When there are multiple perception nodes in the system, a perception control node can be present to control and manage the entire perception service to improve efficiency. The perception control node can be a base station, a terminal, or a core network element.

[0070] FIG. 3 shows a schematic diagram of multiple perception nodes participating in perception according to an example embodiment of the present application. Taking a vehicle-mounted device as a perceived terminal 310 and a terminal or a base station as a perception control node 320 as an example, the perception control node 320 can send a communication signal to the perception node 1 and the perceived terminal 310, and the perception node 1, the perception node 2, and the perception node 3 can send a perception signal to the perceived terminal 310, so that multiple perception nodes jointly participate in perception, improve the accuracy of perception, meet more complex perception service requirements, and provide more abundant perception services.

[0071] In a conventional perception signal design, the perception signal maintains a uniform interval feature in the frequency domain or the time domain. FIG. 4 shows a schematic diagram of a perception signal configuration according to an example embodiment of the present application, where the horizontal axis is the time domain, the unit is a symbol, and the vertical axis is the frequency domain, the unit is a resource element (RE).

[0072] The perception signal is uniformly spaced in the frequency domain, and the frequency domain interval is 4 RE, for example, perception signals are configured on (4, 2), (4, 6), and (4, 10), respectively. The perception signal is periodically present in the time domain, and the time domain interval is configurable, for example, the time domain interval is configured to be 5 symbols. In addition to configuring perception signals on (4, 2), (4, 6), and (4, 10), respectively, perception signals are also configured on (9, 2), (9, 6), and (9, 10), respectively.

[0073] However, for perception, the perception performance is affected by the perception signal parameters, for example, the smaller the frequency domain interval of the perception signal, the greater the unambiguous distance; the smaller the time domain interval of the perception signal, the greater the unambiguous speed, etc. In order to meet the perception performance, a larger unambiguous distance and / or unambiguous speed is required, and the frequency domain interval and / or time domain interval of the perception signal needs to be smaller, thereby causing a large amount of perception signal resource overhead.

[0074] Specifically, taking the Orthogonal Frequency Division Multiplexing (OFDM) pilot signal arrangement mode and the terminal self-generated self-received sensing mode as examples, the maximum unambiguous distance and the maximum unambiguous speed that can be achieved by the sensing signal under the basic configuration can be derived.

[0075] N sensing signals on a symbol are arranged at a frequency interval of N c Δf f Δf f Δf f , where N is the number of subcarriers, and the frequency domain channel response H1 composed of the sensing signals on the symbol is:

[0076] Inverse Fast Fourier Transform (IFFT) of H1 can obtain the distance r between the sensing target and the sensing node. However, since the Fourier transform reflects the phase change between elements, once the phase change is greater than or equal to 2π, it cannot be identified, and thus the maximum unambiguous distance c is the speed of light.

[0077] Similarly, M sensing signals on a subcarrier with a frequency of f c and a wavelength of λ c are arranged at a time interval of M t Δt, where Δt is a time domain unit, and M t is the number of time domain units, which can be a symbol or a slot, thereby obtaining a time domain channel response H2:

[0078] where is an initial phase determined by the frequency f c and the initial distance r0, Fast Fourier Transform (FFT) of H2 can obtain the speed v of the sensing target motion. Since the Fourier transform reflects the phase change between elements, once the phase change is greater than or equal to 2π, it cannot be identified, and thus the maximum unambiguous speed

[0079] From the above derivation, it can be seen that the maximum unambiguous distance decreases as the frequency domain interval of the sensing signal increases, and the maximum unambiguous speed decreases as the time domain interval of the sensing signal increases. In some scenarios, in order to meet the requirements of the sensing service on the maximum unambiguous distance and the maximum unambiguous speed, a large sensing signal resource overhead is required.

[0080] To solve the above problems, the application provides a sensing signal configuration method. FIG. 5 shows a schematic diagram of a sensing signal configuration provided by an example embodiment of the application, the horizontal axis is the time domain, the unit is time slot, and the vertical axis is the frequency domain, the unit is RE.

[0081] The frequency domain intervals {a1, a2, …, a n} of the sensing signal are co-prime, and the time domain intervals {b1, b2, …, b m} are co-prime. Co-prime means that there is no common divisor between two or more intervals except 1. For example, the interval values are 3, 4, and 5, which are co-prime. In the embodiments of the application, the sensing signal can be referred to as signal.

[0082] The frequency domain intervals and the time domain intervals of the sensing signal in FIG. 5 are co-prime (including completely co-prime or incompletely co-prime). In some embodiments, the frequency domain intervals of the sensing signal are co-prime, and the time domain intervals are not co-prime (for example, equal intervals). Alternatively, the time domain intervals of the sensing signal are co-prime, and the frequency domain intervals are not co-prime (for example, equal intervals).

[0083] When the n frequency domain intervals are co-prime, the corresponding maximum unambiguous distance can exceed the maximum unambiguous distance of an equal interval signal with a first interval as the frequency domain interval, and the first interval is the total number of subcarriers / frequency domain interval number (N / n). The n frequency domain intervals are not necessarily completely different, that is, there can be the same frequency domain interval. On the other hand, considering that channel estimation in an actual system requires the signal to have a certain regularity in order to simplify smoothing processing, that is, to reuse the same smoothing filter parameter, a repetitive co-prime signal pattern is designed.

[0084] For example, in the case where only the frequency domain intervals are co-prime and the time domain intervals are the same, in (a) of FIG. 5, the time domain intervals of all the sensing signals are 5 time slots, (0, 0) corresponds to a sensing signal with a frequency domain interval of 3 REs; (0, 3) corresponds to a sensing signal with a frequency domain interval of 4 REs; (0, 7) corresponds to a sensing signal with a frequency domain interval of 5 REs; (5, 0) corresponds to a sensing signal with a frequency domain interval of 3 REs; (5, 3) corresponds to a sensing signal with a frequency domain interval of 4 REs; (5, 7) corresponds to a sensing signal with a frequency domain interval of 5 REs; (10, 0) corresponds to a sensing signal with a frequency domain interval of 3 REs; (10, 3) corresponds to a sensing signal with a frequency domain interval of 4 REs; and (10, 7) corresponds to a sensing signal with a frequency domain interval of 5 REs.

[0085] Similarly, when the m time domain intervals are co-prime, the corresponding maximum unambiguous velocity can exceed the maximum unambiguous velocity of an equal interval signal with a second interval as the time domain interval, and the second interval is the total time domain resource / time domain interval number (M / m). The m time domain intervals are not necessarily completely different, that is, there can be the same time domain interval.

[0086] For example, in the case that only the time domain interval is co-prime and the frequency domain interval is the same, in (b) of FIG. 5, the frequency domain interval of all the sensing signals is 6 RE, (0, 0) corresponds to the sensing signal with a time domain interval of 3 slots; (0, 6) corresponds to the sensing signal with a time domain interval of 3 slots; (0, 12) corresponds to the sensing signal with a time domain interval of 3 slots; (3, 0) corresponds to the sensing signal with a time domain interval of 7 slots; (3, 6) corresponds to the sensing signal with a time domain interval of 7 slots; (3, 12) corresponds to the sensing signal with a time domain interval of 7 slots; (10, 0) corresponds to the sensing signal with a time domain interval of 3 slots; (10, 6) corresponds to the sensing signal with a time domain interval of 3 slots; (10, 12) corresponds to the sensing signal with a time domain interval of 3 slots.

[0087] In the case that the time domain interval is co-prime and the frequency domain interval is co-prime, in (c) of FIG. 5, taking the frequency domain interval including {3, 4, 5} and the time domain interval including {3, 7} as an example, (0, 0) corresponds to the sensing signal with a frequency domain interval of 3 RE and a time domain interval of 3 slots; (0, 3) corresponds to the sensing signal with a frequency domain interval of 4 RE and a time domain interval of 7 slots; (0, 7) corresponds to the sensing signal with a frequency domain interval of 5 RE and a time domain interval of 3 slots; (3, 0) corresponds to the sensing signal with a frequency domain interval of 3 RE and a time domain interval of 3 slots; (3, 3) corresponds to the sensing signal with a frequency domain interval of 4 RE and a time domain interval of 7 slots; (3, 7) corresponds to the sensing signal with a frequency domain interval of 5 RE and a time domain interval of 3 slots; (10, 0) corresponds to the sensing signal with a frequency domain interval of 3 RE and a time domain interval of 3 slots; (10, 3) corresponds to the sensing signal with a frequency domain interval of 4 RE and a time domain interval of 7 slots; (10, 7) corresponds to the sensing signal with a frequency domain interval of 5 RE and a time domain interval of 3 slots.

[0099] In some embodiments, part of the plurality of frequency domain interval values are co-prime, and part of the plurality of frequency domain interval values are identical.

[0100] The identical frequency domain interval values are allowed to exist zero, one or more, but at least two co-prime frequency domain interval values exist, that is, multiple frequency domain interval values cannot all be identical. For example, the frequency domain interval comprises {3, 4, 5, 5, 7}, 3, 4, 5, 7 are co-prime, and the identical frequency domain interval value is 5.

[0101] In some embodiments, part of the plurality of time domain interval values are co-prime, and part of the plurality of time domain interval values are identical.

[0104] For example, the minimum granularity of frequency domain resource scheduling of the 5G system is a resource block (RB), one RB contains 12 subcarriers, the frequency domain interval includes {3, 4, 5}, and the sum of all frequency domain interval values is 12; the minimum granularity of scheduling of the 5G system is a time slot, one time slot contains 14 symbols, the time domain interval includes {3, 4, 7}, and the sum of all time domain interval values is 14.

[0105] In some embodiments, the first node is a sensing signal sending node or a sensing resource management node.

[0106] Frequency domain related information:

[0107] In some embodiments, the sensing signal configuration information further includes: a frequency domain cycle interval, the frequency domain cycle interval being used to indicate a period of cyclic occurrence of the sensing signal in the frequency domain.

[0108] The frequency domain cycle interval can also be replaced by the names of frequency domain period, frequency domain cycle period, etc., and the embodiments of the present application do not limit this. The frequency domain cycle interval is taken as an example for illustration.

[0109] As shown in FIG. 5, the frequency domain cycle interval is 12 REs, and (0, 0), (0, 3), (0, 7) are taken as an example of a group of sensing signals, each group of sensing signals cyclically occurs in the frequency domain with a period of 12 REs.

[0110] By way of example but not limitation, the value of the frequency domain cycle interval is a first integer multiple of the sum of all frequency domain interval values in at least two frequency domain interval values.

[0111] By way of example but not limitation, the value of the frequency domain cycle interval is the sum of all frequency domain interval values in at least two frequency domain interval values.

[0112] For example, in the case where the frequency domain interval includes {3, 4, 5}, the sum of all frequency domain interval values is 12, and then the value of the frequency domain cycle interval can be 12 or a first integer multiple of 12, such as 12, 24, 36, etc.

[0113] In some embodiments, the method further includes: in the case where the sensing signal configuration information does not include the frequency domain cycle interval, determining that the value of the frequency domain cycle interval is the sum of all frequency domain interval values in at least two frequency domain interval values; wherein the frequency domain cycle interval is used to indicate a period of cyclic occurrence of the sensing signal in the frequency domain.

[0114] The value of the frequency domain interval is the sum of all the frequency domain interval values in the at least two frequency domain interval values, or is a first integer multiple of the sum of all the frequency domain interval values, which can correspond to the minimum granularity of resource scheduling of the communication system. For example, in the case of a minimum granularity of RB, and one RB containing 12 subcarriers, the frequency domain interval is a first integer multiple of 12, such as 12, 24, 36, etc., which can maintain the same resource scheduling granularity as the communication system, facilitate coordinated scheduling of resources, and avoid resource fragmentation.

[0115] In some embodiments, the sensing signal configuration information further comprises a frequency domain offset; wherein the frequency domain offset is used to indicate a position of a first sensing signal in the frequency domain interval, an offset compared with a starting position of the frequency domain interval, or is used to indicate an offset of a starting position of the frequency domain interval compared with a first reference point, and the frequency domain interval is used to indicate a period of cyclic occurrence of the sensing signal in the frequency domain.

[0116] By way of example but not limitation, the first reference point comprises at least one of the following: an activated frequency domain resource starting point; a starting point of a system bandwidth; a starting point agreed by a communication protocol; a carrier starting point; a carrier reference point. The first reference point can be a pre-configured point, a pre-defined point, or any possible form of determined reference point, and embodiments of the present application are not limited in this regard.

[0117] FIG. 7 shows a schematic diagram of a sensing signal configuration according to an example embodiment of the present application. The frequency domain interval of the sensing signal in FIG. 7 comprises {a1, a2, …, a n-1 , with a0 as the frequency domain offset (bias), and P as the frequency domain interval (period) repeatedly occurring in the bandwidth occupied by the sensing signal, wherein the order of a1, a2, …, a n-1 does not affect the maximum unambiguous distance, and P = a1 + a2 + … + a n .

[0118] The frequency domain offset a0 in (a) of FIG. 7 indicates a position P1 of a first sensing signal in the frequency domain interval P, and an offset compared with a starting position P0 of the frequency domain interval. The frequency domain offset a0 in (b) of FIG. 7 indicates an offset of a starting position P1 of the frequency domain interval compared with a first reference point P2, and the two indicating manners are essentially equivalent.

[0119] In some embodiments, the n frequency domain intervals are co-prime, or there are partially same frequency domain intervals in the n frequency domain intervals, and there are at least two co-prime frequency domain intervals.

[0120] By way of example but not limitation, {a1, a2, …, a n-1} are all different values, or a1 = a2, and the other frequency domain intervals are all different from a1 and a2, and embodiments of the present application are not limited in this regard.

[0121] In some embodiments, assuming that the granularity of frequency domain resource scheduling is N, P is the first integer multiple of N. For example, the minimum granularity of scheduling of a 5G system is RB, and one RB contains 12 subcarriers, then P is the first integer multiple of 12, such as 12, 24, 36, etc. For another example, the minimum granularity of reference signal configuration is subband, and one subband contains 48 subcarriers, then P is the first integer multiple of 48, such as 48, 96, 144, etc. The embodiments of the present application do not limit this.

[0122] In some embodiments, in the sensing signal configuration information, the frequency domain interval pattern is indicated by a first index or a first value.

[0123] In some embodiments, the first index is used to indicate a frequency domain interval pattern in a frequency domain interval pattern pool, and the frequency domain interval pattern pool contains one or more frequency domain interval patterns.

[0124] By way of example but not limitation, the one or more frequency domain interval patterns contained in the frequency domain interval pattern pool include at least one of the following: a first frequency domain interval pattern: 3RE, 4RE, 5RE; a second frequency domain interval pattern: 5RE, 7RE; a third frequency domain interval pattern: 7RE, 8RE, 9RE; a fourth frequency domain interval pattern: 11RE, 13RE; wherein a resource element is the minimum unit of frequency domain resource mapping.

[0125] For example, the first frequency domain interval pattern is indicated by a first index with a value of 1 or a binary number 00, the second frequency domain interval pattern is indicated by a first index with a value of 2 or a binary number 01, the third frequency domain interval pattern is indicated by a first index with a value of 3 or a binary number 10, and the fourth frequency domain interval pattern is indicated by a first index with a value of 4 or a binary number 11.

[0126] Obtaining the frequency domain interval pattern from the preset frequency domain interval pattern pool can meet the needs of most common scenarios and reduce the complexity of system design.

[0127] Time domain related information:

[0128] In some embodiments, the sensing signal configuration information further includes time domain cycle interval, which is used to indicate the period of the cyclic occurrence of the sensing signal in the time domain.

[0129] The time domain cycle interval can also be replaced by the names of time domain period, time domain cycle period, etc. The embodiments of the present application do not limit this, and the time domain cycle interval is taken as an example for illustration.

[0130] As shown in FIG. 5, the time domain cycle interval is 10 slots, and (0, 0), (3, 0) is taken as an example of a group of sensing signals, and each group of sensing signals cyclically occurs in the time domain with a period of 10 slots.

[0131] As an example but not limitation, the value of the time domain cycle interval is a second integer multiple of the sum of all time domain interval values in the at least two time domain interval values.

[0132] As an example but not limitation, the value of the time domain cycle interval is the sum of all time domain interval values in the at least two time domain interval values.

[0133] For example, in the case of time domain intervals including {3, 7}, the sum of all time domain interval values is 10, and the value of the time domain cycle interval can be 10 or a second integer multiple of 10, such as 10, 20, 30, etc.

[0134] In some embodiments, the method further comprises: in the case that the sensing signal configuration information does not include the time domain cycle interval, determining that the value of the time domain cycle interval is the sum of all time domain interval values in the at least two time domain interval values; wherein the time domain cycle interval is used to indicate the period of the cyclic occurrence of the sensing signal in the time domain.

[0135] The value of the time domain cycle interval being the sum of all time domain interval values in the at least two time domain interval values, or being a second integer multiple of the sum of all time domain interval values, can correspond to the minimum granularity of the resource scheduling of the communication system, for example, in the case of the minimum granularity being 10 time slots, the time domain cycle interval being a second integer multiple of 10, such as 10, 20, 30, etc., can maintain the same resource scheduling granularity as the communication system, facilitate the coordinated scheduling of resources, and avoid resource fragmentation.

[0136] In some embodiments, the sensing signal configuration information further includes a time domain offset; wherein the time domain offset is used to indicate the time domain position of the first sensing signal within the time domain cycle interval, the offset amount compared to the starting position of the time domain cycle interval, or is used to indicate the offset amount of the starting position of the time domain cycle interval compared to the second reference point, and the time domain cycle interval is used to indicate the period of the cyclic occurrence of the sensing signal in the time domain.

[0137] As an example but not limitation, the second reference point includes at least one of the following: the time domain position where the configuration signaling is located; the time domain position where the first reference frame configured by the network is located; the time domain position where the second reference frame agreed by the communication protocol is located; wherein the time domain position where the configuration signaling is located includes the symbol where the configuration signaling is located or the symbol where the configuration signaling ends. The second reference point can be a reference point determined in any possible form, such as a pre-configured point, a pre-defined point, etc., and the embodiments of the present application do not limit this.

[0138] FIG. 8 shows a schematic diagram of sensing signal configuration provided by an example embodiment of the present application. As with the frequency domain interval, in the time domain, the time domain interval of the sensing signal includes {b1, b2, …, b m-1}, with b0 as the time-domain offset (bias), and T as the time-domain cycle interval (period) that repeats within the time-domain resource occupied by the sensing signal, where T = b1 + b2 + … + b m , and b0 < b1 < b2 < … < bP-1 < bP, and b0 < b1 < b2 < … < bP-1 < bP are not required to be arranged in ascending or descending order. m .

[0139] The time-domain offset b0 in (a) of FIG. 8 refers to the time-domain position T1 of the first sensing signal within the time-domain cycle interval T, which is offset from the starting position T0 of the time-domain cycle interval. The time-domain offset b0 in (b) of FIG. 8 refers to the offset of the starting position T1 of the time-domain cycle interval from the second reference point T2, and the two indications are essentially equivalent.

[0140] In some embodiments, assuming that the granularity of time-domain resource scheduling is M, T is a second integer multiple of M. For example, the minimum granularity of scheduling in a 5G system is a slot, and one slot contains 14 symbols. Then, T is a second integer multiple of 14, such as 14, 28, 42, etc. For another example, considering that the frame structure is the basis of the entire time-domain structure, the minimum granularity of the frame structure can also be referred to, for example, 10 slots, and then P is a second integer multiple of 10*14 = 140, such as 140, 280, 420, etc., which is not limited in the embodiments of the present application.

[0141] In some embodiments, in the sensing signal configuration information, the time-domain interval pattern is indicated by a second index or a second value.

[0142] In some embodiments, the second index is used to indicate a time-domain interval pattern in a time-domain interval pattern pool, and the time-domain interval pattern pool contains one or more time-domain interval patterns.

[0143] By way of example but not limitation, the one or more time-domain interval patterns contained in the time-domain interval pattern pool include at least one of the following: a first time-domain interval pattern: 3 slots, 7 slots; a second time-domain interval pattern: 9 slots, 11 slots; a third time-domain interval pattern: 5 symbols, 9 symbols; and a fourth time-domain interval pattern: 3 symbols, 4 symbols, 7 symbols.

[0144] For example, the first time-domain interval pattern is indicated by a second index with a value of 1 or a binary number 00, the second time-domain interval pattern is indicated by a second index with a value of 2 or a binary number 01, the third time-domain interval pattern is indicated by a second index with a value of 3 or a binary number 10, and the fourth time-domain interval pattern is indicated by a second index with a value of 4 or a binary number 11.

[0145] Obtaining the time-domain interval pattern from the preset time-domain interval pattern pool can meet the needs of most common scenarios and reduce the complexity of system design.

[0146] Maximum unambiguous range and maximum unambiguous velocity:

[0147] In some embodiments, the method further includes: receiving the first message; wherein the first message comprises at least one of: the maximum unambiguous range of the sensing service and the maximum unambiguous velocity of the sensing service.

[0148] The first message is sent by a sensing service management node for indicating the sensing service requirement, and the sensing service management node can be at a core network, or at a base station side, or at a terminal side.

[0149] When a pulse emitted by a first node (e.g., a radar) meets a backscattering wave generated by a target object at the maximum unambiguous range and returns to the radar, the next pulse is just emitted. That is, the radar wave propagates to the target object located at the maximum unambiguous range, and then the echo returns to the radar, and the time used is just the time interval between two pulses.

[0150] When the maximum pulse phase shift of one pulse to the next pulse that can be measured by a first node (e.g., a radar) is 180°, the target object radial velocity value corresponding to the 180° pulse phase shift is the maximum unambiguous velocity.

[0151] In some embodiments, the maximum unambiguous velocity can also be the maximum unambiguous Doppler.

[0152] The meanings expressed by the maximum unambiguous range, the maximum unambiguous distance, and the maximum non-ambiguous range are the same, and the meanings expressed by the maximum unambiguous velocity, the maximum unambiguous speed, and the maximum non-ambiguous speed are the same, and the embodiments of the present application are only exemplified by the maximum unambiguous range and the maximum unambiguous velocity.

[0153] In some embodiments, the method further includes: determining a sensing signal configuration based on the first message; and sending sensing signal configuration information, including: sending the sensing signal configuration information based on the sensing signal configuration.

[0154] The first node determines at least one of a frequency domain interval pattern, a time domain interval pattern, a frequency domain cycle interval, a time domain cycle interval, a frequency domain offset, and a time domain offset based on the first message.

[0155] Maximum unambiguous range example:

[0156] Taking a terminal as an unmanned aerial vehicle (UAV) for example, according to a related protocol, in a low-altitude scene of an open village and field, the distance between base stations is 1732 meters, the height of the unmanned aerial vehicle is 300 meters, and the height of the base station is 35 meters, and in this case, the farthest distance between the unmanned aerial vehicle and the base station is about 1253.1 meters. Therefore, the maximum unambiguous range should be at least greater than 1253.1 meters.

[0157] In the case of a subcarrier spacing of 60 kHz, the maximum unambiguous distance corresponding to consecutive subcarriers is 2500 meters, and the maximum unambiguous distance under a subcarrier arrangement with a frequency domain interval of 4 REs is The performance requirement is not met. As shown in FIG. 9, multiple sample values appear when the detection distance exceeds 625 meters, that is, the maximum unambiguous distance is 625 meters at this time.

[0158] For the maximum unambiguous distance requirement of the perception service, that is, the maximum unambiguous distance is greater than 1253.1 meters, a perception signal design with a frequency domain interval including 3 REs, 4 REs, and 5 REs is adopted. On the one hand, 3, 4, and 5 are co-prime numbers, and the maximum unambiguous distance corresponding to the signal design with co-prime frequency domain intervals is the same as the maximum unambiguous distance corresponding to consecutive subcarriers. On the other hand, 3+4+5=12, which corresponds to the minimum granularity RB (12 subcarriers) of resource scheduling of a communication system, is more suitable for an integrated sensing and communication system, maintains the same resource scheduling granularity as the communication system, facilitates coordinated scheduling of resources, and avoids resource fragmentation.

[0159] If a uniform signal structure design is adopted, in order to meet the requirement of a maximum unambiguous distance of 2500 meters, the perception signal needs to be arranged on consecutive subcarriers. The perception signal design with a frequency domain interval including 3 REs, 4 REs, and 5 REs arranges fewer perception signals on the basis of meeting the maximum unambiguous distance requirement, thereby saving perception signal overhead.

[0160] As shown in FIG. 10(a), when the detection distance exceeds 625 meters, no multiple sample values appear, that is, the 625-meter limit has been broken, and when the detection distance exceeds 2500 meters, multiple sample values begin to appear again, as shown in FIG. 10(b), that is, the maximum unambiguous distance is 2500 meters.

[0161] In some embodiments, for the perception service requirement of a larger unambiguous distance, a larger scheduling granularity is adopted.

[0162] For example, 24 subcarriers (2 RBs) are taken as one scheduling unit, and a perception signal design with a frequency domain interval including 7 REs, 8 REs, and 9 REs can be adopted, thereby reducing the perception signal overhead.

[0163] In some embodiments, under the condition of the same perception signal overhead, a co-prime frequency domain interval design can provide a larger maximum unambiguous distance.

[0164] Figure 11 shows the performance of the co-prime sensing signal design with frequency domain interval including: 7 RE, 8 RE, 9 RE, compared with the performance of the sensing signal design with equal frequency domain interval 8 RE. Both of them have the same sensing signal overhead, but Figure 11 (a) shows that the maximum unambiguous range corresponding to the sensing signal design with equal frequency domain interval 8 RE is 625 meters, and Figure 11 (b) shows that the maximum unambiguous range corresponding to the co-prime sensing signal design with frequency domain interval including: 7 RE, 8 RE, 9 RE is greater than 625 meters, so that the sensing signal can cover a larger range under the condition of the same sensing signal overhead.

[0165] Maximum unambiguous speed example:

[0166] According to the relevant agreement, the speed of the unmanned aerial vehicle is 160 kilometers per hour (km / h), which is approximately equal to 44.44 meters per second (m / s), so the maximum unambiguous speed should be at least greater than 44.44 m / s.

[0167] In the case of carrier frequency 3 GHz and subcarrier spacing 15 kHz, the equal time slot interval is 1, that is, the maximum unambiguous speed corresponding to the sensing signal under the arrangement of continuous time slots is 50 m / s, and the maximum unambiguous speed corresponding to the sensing signal under the arrangement of time slots with equal time slot interval 4 is Does not meet the performance requirement.

[0168] Figure 12 shows a schematic diagram of the detection speed corresponding to the sensing signal under the arrangement of time slots with equal time slot interval 4. When the detection speed exceeds 12.5 m / s, multiple samples will appear, that is, the maximum unambiguous speed is 12.5 m / s.

[0169] And the sensing signal design with time domain interval including: 3 symbols, 4 symbols, 7 symbols can reduce the sensing signal overhead while meeting the maximum unambiguous speed of 50 m / s. As shown in Figure 13 (a), when the detection speed exceeds 12.5 m / s, multiple samples will no longer appear, that is, the limit of 12.5 m / s has been broken, and when the detection speed exceeds 50 m / s, multiple samples will appear again, as shown in Figure 13 (b), that is, the maximum unambiguous speed is 50 m / s.

[0170] In some embodiments, for the sensing service requirement of greater unambiguous speed, a greater scheduling granularity is used.

[0171] For example, in order to be compatible with the granularity of 10 time slots of the frame structure configuration, the sensing signal design with time domain interval including: 3 time slots, 7 time slots can be used.

[0172] In some embodiments, under the condition of the same sensing signal overhead, the co-prime design of time domain interval can provide a greater maximum unambiguous speed.

[0173] Figure 14 gives the performance comparison of the time-domain interval including: 3 time slots, 7 time slots, the sensing signal design, and the performance of the equal time-domain interval 5 time slots, the sensing signal design. Both sensing signal overheads are the same, but Figure 14(a) shows that the equal time-domain interval 5 time slots, the sensing signal design corresponds to the maximum unambiguous speed of 10 m / s, and Figure 14(b) shows that the time-domain interval including: 3 time slots, 7 time slots, the sensing signal design corresponds to the maximum unambiguous speed greater than 10 m / s, so that under the condition of the same sensing signal overhead, the terminal (such as a drone) can stably transmit and receive the sensing signal even in faster motion.

[0175] Taking the terminal as a drone as an example, according to the relevant protocol, in the low-altitude scene of open village and field, the base station interval is 1732 meters, the height of the drone is 300 meters, and the height of the base station is 35 meters. Under the condition that the farthest distance between the drone and the base station is about 1253.1 meters, the speed is about 44.44 m / s, then the maximum unambiguous distance should be at least greater than 1253.1 meters, and the maximum unambiguous speed should be at least greater than 44.44 m / s.

[0176] In the case of subcarrier spacing of 30 kHz, the maximum unambiguous distance of continuous subcarriers is 5000 meters, and the maximum unambiguous distance of subcarriers arranged under the frequency domain interval of 4 RE is 1250 meters, which does not meet the performance requirements. The frequency domain interval including: 3 RE, 4 RE, 5 RE, the sensing signal design, on the basis of meeting the maximum unambiguous distance, arranges less sensing signals, and saves sensing signal overhead.

[0177] In the time domain range, for example, in the case of carrier frequency of 3 GHz and subcarrier spacing of 30 kHz, the maximum unambiguous speed corresponding to the sensing signal under continuous time slot arrangement is 100 m / s, and the maximum unambiguous speed corresponding to the sensing signal under time slot arrangement with equal time slot interval of 4 is 25 m / s, which does not meet the performance requirements. The time-domain interval including: 3 time slots, 7 time slots, the sensing signal design, can arrange less sensing signals on the basis of meeting the maximum unambiguous speed, and save sensing signal overhead.

[0178] In summary, the method provided in the embodiment sends sensing signal configuration information, which includes at least one of a frequency domain interval pattern and a time domain interval pattern. The frequency domain interval pattern includes multiple frequency domain interval values, at least two of which are co-prime. The time domain interval pattern includes multiple time domain interval values, at least two of which are co-prime. Compared with an equal-interval sensing signal structure, a co-prime sensing signal structure corresponding to co-prime frequency domain interval values and / or co-prime time domain interval values has a smaller interval and thus a smaller sensing signal overhead, while meeting the same maximum unambiguous distance and / or maximum unambiguous velocity requirement. In the case of the same sensing signal overhead, the co-prime sensing signal structure can provide a larger maximum unambiguous distance and / or maximum unambiguous velocity.

[0179] The method provided in the embodiment further receives a first message to obtain a sensing service requirement, determines a sensing signal configuration according to the sensing service requirement, and thus better adapts to the sensing service requirement, more accurately allocates resources, and thus improves resource utilization.

In some embodiments, part of the multiple frequency domain interval values are co-prime, and part of the multiple frequency domain interval values are the same.

[0191] The same frequency domain interval value allows zero, one or more to exist, but at least two co-prime frequency domain interval values exist, i.e. multiple frequency domain interval values cannot all be the same. For example, the frequency domain interval includes {3, 4, 5, 5, 7}, 3, 4, 5, 7 are co-prime, and the same frequency domain interval value is 5.

[0192] In some embodiments, part of the multiple time domain interval values are co-prime, and part of the multiple time domain interval values are the same.

[0194] In some embodiments, the sum of all frequency domain interval values in the at least two frequency domain interval values is the frequency domain resource scheduling granularity; the sum of all time domain interval values in the at least two time domain interval values is the time domain resource scheduling granularity.

[0199] The second node can determine the sensing signal configuration according to the received sensing signal configuration information, or determine the sensing signal configuration according to the signal pattern agreed by the communication protocol. The present application does not limit this, and mainly takes the second node determining the sensing signal configuration according to the received sensing signal configuration information as an example for illustration.

[0200] Frequency domain related information:

[0201] In some embodiments, the sensing signal configuration further includes: a frequency domain cyclic interval, the frequency domain cyclic interval being used to indicate a period of cyclic occurrence of the sensing signal in the frequency domain.

[0202] As shown in FIG. 5, the frequency domain cyclic interval is 12 REs, and (0, 0), (0, 3), (0, 7) are taken as an example of a group of sensing signals, and each group of sensing signals cyclically occurs in the frequency domain with a period of 12 REs.

[0203] The frequency domain cyclic interval can also be replaced by the names of frequency domain period, frequency domain cyclic period, etc., and the embodiments of the present application do not limit this, and the frequency domain cyclic interval is taken as an example for illustration.

[0204] By way of example but not limitation, the value of the frequency domain cyclic interval is a first integer multiple of the sum of all frequency domain interval values in at least two frequency domain interval values.

[0205] By way of example but not limitation, the value of the frequency domain cyclic interval is the sum of all frequency domain interval values in at least two frequency domain interval values.

[0206] For example, in the case where the frequency domain interval includes {3, 4, 5}, the sum of all frequency domain interval values is 12, and then the value of the frequency domain cyclic interval can be 12, or a first integer multiple of 12, such as 12, 24, 36, etc.

[0207] In some embodiments, the method further includes: in the case where the sensing signal configuration does not include the frequency domain cyclic interval, determining that the value of the frequency domain cyclic interval is the sum of all frequency domain interval values in at least two frequency domain interval values; wherein the frequency domain cyclic interval is used to indicate a period of cyclic occurrence of the sensing signal in the frequency domain.

[0208] The value of the frequency domain interval is the sum of all the frequency domain interval values in the at least two frequency domain interval values, or is a first integer multiple of the sum of all the frequency domain interval values, which corresponds to the minimum granularity of resource scheduling of the communication system. For example, in the case of a minimum granularity of RB, and one RB containing 12 subcarriers, the frequency domain interval is a first integer multiple of 12, such as 12, 24, 36, etc., which can maintain the same resource scheduling granularity as the communication system, facilitate coordinated scheduling of resources, and avoid resource fragmentation.

[0209] In some embodiments, the sensing signal configuration further includes a frequency domain offset; wherein the frequency domain offset is used to indicate a position of a first sensing signal in the frequency domain interval, an offset compared with a starting position of the frequency domain interval, or an offset used to indicate a starting position of the frequency domain interval compared with a first reference point, and the frequency domain interval is used to indicate a period of cyclic occurrence of the sensing signal in the frequency domain.

[0210] By way of example but not limitation, the first reference point includes at least one of the following: an activated frequency domain resource starting point; a starting point of a system bandwidth; a starting point agreed by a communication protocol; a carrier starting point; a carrier reference point. The first reference point can be a pre-configured point, a pre-defined point, or any possible form of reference point, and the embodiments of the present application are not limited in this regard.

[0211] In some embodiments, in the sensing signal configuration, the frequency domain interval pattern is represented by a first index or a first value.

[0212] In some embodiments, the first index is used to indicate a frequency domain interval pattern in a frequency domain interval pattern pool, and the frequency domain interval pattern pool contains one or more frequency domain interval patterns.

[0213] By way of example but not limitation, the one or more frequency domain interval patterns contained in the frequency domain interval pattern pool include at least one of the following: a first frequency domain interval pattern: 3RE, 4RE, 5RE; a second frequency domain interval pattern: 5RE, 7RE; a third frequency domain interval pattern: 7RE, 8RE, 9RE; a fourth frequency domain interval pattern: 11RE, 13RE; wherein a resource element is the smallest unit of frequency domain resource mapping.

[0214] For example, the first frequency domain interval pattern is represented by a first index with a value of 1 or a binary number 00, the second frequency domain interval pattern is represented by a first index with a value of 2 or a binary number 01, the third frequency domain interval pattern is represented by a first index with a value of 3 or a binary number 10, and the fourth frequency domain interval pattern is represented by a first index with a value of 4 or a binary number 11.

[0215] Obtaining the frequency domain interval pattern from the pre-configured frequency domain interval pattern pool can meet the needs of most common scenarios, and can also reduce the complexity of system design.

[0216] time domain related information:

[0217] In some embodiments, the sensing signal configuration further comprises a time domain cycle interval, the time domain cycle interval being used to indicate a period in which the sensing signal cyclically appears in the time domain.

[0218] The time domain cycle interval can also be equivalently replaced by a time domain period, a time domain cycle period, etc., and the embodiments of the present application do not limit this. The time domain cycle interval is taken as an example for illustration.

[0219] As shown in FIG. 5, the time domain cycle interval is 10 time slots, and (0, 0), (3, 0) is taken as an example of a group of sensing signals, each group of sensing signals cyclically appears in the time domain with a period of 10 time slots.

[0220] By way of example but not limitation, the value of the time domain cycle interval is a second integer multiple of the sum of all time domain interval values in at least two time domain interval values.

[0221] By way of example but not limitation, the value of the time domain cycle interval is the sum of all time domain interval values in at least two time domain interval values.

[0222] For example, in the case where the time domain interval comprises {3, 7}, the sum of all time domain interval values is 10, and then the value of the time domain cycle interval can be 10 or a second integer multiple of 10, such as 10, 20, 30, etc.

[0223] In some embodiments, the method further comprises: in the case where the sensing signal configuration does not comprise a time domain cycle interval, determining that the value of the time domain cycle interval is the sum of all time domain interval values in at least two time domain interval values; wherein the time domain cycle interval is used to indicate a period in which the sensing signal cyclically appears in the time domain.

[0224] The value of the time domain cycle interval being the sum of all time domain interval values in at least two time domain interval values, or being a second integer multiple of the sum of all time domain interval values, can correspond to the minimum granularity of the resource scheduling of the communication system, for example, in the case where the minimum granularity is 10 time slots, the time domain cycle interval is a second integer multiple of 10, such as 10, 20, 30, etc., which can maintain the same resource scheduling granularity as the communication system, facilitate the coordinated scheduling of resources, and avoid resource fragmentation.

[0225] In some embodiments, the sensing signal configuration further comprises a time domain offset; wherein the time domain offset is used to indicate a time domain position of a first sensing signal within the time domain cycle interval, an offset amount compared with a starting position of the time domain cycle interval, or an offset amount of the starting position of the time domain cycle interval compared with a second reference point, the time domain cycle interval being used to indicate a period in which the sensing signal cyclically appears in the time domain.

[0226] By way of example but not limitation, the second reference point comprises at least one of: a time domain position where the configuration signaling is located; a time domain position where the first reference frame configured by the network is located; a time domain position where the second reference frame agreed by the communication protocol is located; wherein the time domain position where the configuration signaling is located comprises a symbol where the configuration signaling is located or a symbol where the configuration signaling ends. The second reference point can be a pre-configured point, a pre-defined point, or any possible form of determined reference point, and embodiments of the present application do not limit this.

[0227] In some embodiments, in the sensing signal configuration, the time domain interval pattern adopts a second index or a second value to represent.

[0228] In some embodiments, the second index is used to indicate a time domain interval pattern in a time domain interval pattern pool, and the time domain interval pattern pool contains one or more time domain interval patterns.

[0229] By way of example but not limitation, the one or more time domain interval patterns contained in the time domain interval pattern pool comprise at least one of: a first time domain interval pattern: 3 slots, 7 slots; a second time domain interval pattern: 9 slots, 11 slots; a third time domain interval pattern: 5 symbols, 9 symbols; a fourth time domain interval pattern: 3 symbols, 4 symbols, 7 symbols.

[0230] For example, the first time domain interval pattern is represented by the second index with a value of 1 or a binary number 00, the second time domain interval pattern is represented by the second index with a value of 2 or a binary number 01, the third time domain interval pattern is represented by the second index with a value of 3 or a binary number 10, and the fourth time domain interval pattern is represented by the second index with a value of 4 or a binary number 11.

[0231] Obtaining the time domain interval pattern from the preset time domain interval pattern pool can meet the needs of most common scenarios and reduce the complexity of system design.

[0232] The specific implementation details of the maximum unambiguous range and the maximum unambiguous velocity refer to the embodiment of FIG. 6, which will not be repeated here.

[0233] To sum up, the method provided in the embodiment determines a sensing signal configuration, which includes at least one of a frequency domain interval pattern and a time domain interval pattern. The frequency domain interval pattern includes a plurality of frequency domain interval values, at least two of which are co-prime. The time domain interval pattern includes a plurality of time domain interval values, at least two of which are co-prime. Compared with an equal-interval sensing signal structure, a co-prime sensing signal structure corresponding to co-prime frequency domain interval values and / or co-prime time domain interval values has a smaller interval and thus a larger sensing signal overhead under the condition of meeting the same maximum unambiguous distance and / or maximum unambiguous velocity requirement. Under the condition of the same sensing signal overhead, the co-prime sensing signal structure can provide a larger maximum unambiguous distance and / or maximum unambiguous velocity.

[0234] In the above embodiment, the embodiment corresponding to FIG. 6 and the embodiment corresponding to FIG. 15 can be implemented separately or in combination, which is not limited herein.

[0235] FIG. 16 shows a block diagram of a first sensing signal configuration apparatus provided in an example embodiment of the present application. The apparatus can be implemented as a first node or a part of the first node by software or hardware or a combination of both, and the apparatus includes:

[0236] The sending module 1610 is configured to send sensing signal configuration information, which includes at least one of a frequency domain interval pattern and a time domain interval pattern. The frequency domain interval pattern is used to indicate the interval between adjacent sensing signals in the frequency domain direction, and the time domain interval pattern is used to indicate the interval between adjacent sensing signals in the time domain direction. The frequency domain interval pattern includes a plurality of frequency domain interval values, any two of which are co-prime or identical. At least two of the plurality of frequency domain interval values are co-prime. The time domain interval pattern includes a plurality of time domain interval values, any two of which are co-prime or identical. At least two of the plurality of time domain interval values are co-prime.

[0237] In a possible design of the embodiment, the sensing signal configuration information includes the frequency domain interval pattern.

[0238] In a possible design of the embodiment, the sensing signal configuration information includes the time domain interval pattern.

[0239] In a possible design of the embodiment, the sensing signal configuration information includes the frequency domain interval pattern and the time domain interval pattern.

[0240] In a possible design of the present embodiment, when the sensing signal configuration information comprises a frequency domain interval pattern and a time domain interval pattern, the frequency domain interval pattern comprises a plurality of frequency domain interval values, any two of the plurality of frequency domain interval values are co-prime or identical, and at least two of the plurality of frequency domain interval values are co-prime; and the time domain interval pattern comprises a plurality of time domain interval values, any two of the plurality of time domain interval values are identical.

[0241] In a possible design of the present embodiment, when the sensing signal configuration information comprises a frequency domain interval pattern and a time domain interval pattern, the frequency domain interval pattern comprises a plurality of frequency domain interval values, any two of the plurality of frequency domain interval values are identical; and the time domain interval pattern comprises a plurality of time domain interval values, any two of the plurality of time domain interval values are co-prime or identical, and at least two of the plurality of time domain interval values are co-prime.

[0242] In a possible design of the present embodiment, when the sensing signal configuration information comprises a frequency domain interval pattern and a time domain interval pattern, the frequency domain interval pattern comprises a plurality of frequency domain interval values, any two of the plurality of frequency domain interval values are co-prime or identical, and at least two of the plurality of frequency domain interval values are co-prime; and the time domain interval pattern comprises a plurality of time domain interval values, any two of the plurality of time domain interval values are co-prime or identical, and at least two of the plurality of time domain interval values are co-prime. In a possible design of the present embodiment, part of the plurality of frequency domain interval values are co-prime, and part of the plurality of frequency domain interval values are identical.

[0243] The same frequency domain interval values are allowed to exist zero, one or more, but at least two co-prime frequency domain interval values exist, that is, multiple frequency domain interval values are not all identical. For example, the frequency domain intervals comprise {3, 4, 5, 5, 7}, 3, 4, 5, and 7 are co-prime, and the same frequency domain interval value is 5.

[0244] In a possible design of the present embodiment, part of the plurality of frequency domain interval values are co-prime, and part of the plurality of frequency domain interval values are identical.

[0245] The same time domain interval values are allowed to exist zero, one or more, but at least two co-prime time domain interval values exist, that is, multiple time domain interval values are not all identical. For example, the time domain intervals comprise {3, 5, 5, 7}, 3, 5, and 7 are co-prime, and the same time domain interval value is 5.

[0246] In a possible design of the present embodiment, the sum of all frequency domain interval values in the at least two frequency domain interval values is the frequency domain resource scheduling granularity, and the sum of all time domain interval values in the at least two time domain interval values is the time domain resource scheduling granularity.

[0247] For example, the minimum granularity of frequency domain resource scheduling of the 5G system is a resource block (RB), one RB contains 12 subcarriers, the frequency domain interval includes {3, 4, 5}, and the sum of all frequency domain interval values is 12; the minimum granularity of scheduling of the 5G system is a time slot, one time slot contains 14 symbols, the time domain interval includes {3, 4, 7}, and the sum of all time domain interval values is 14.

[0248] In a possible design of the embodiment, the first awareness signal configuration device is an awareness signal sending node or an awareness resource management node.

[0249] The frequency domain related information includes:

[0250] In a possible design of the embodiment, the awareness signal configuration information further includes a frequency domain cycle interval, the frequency domain cycle interval being used to indicate a cycle of cyclically appearing of the awareness signal in the frequency domain.

[0251] The frequency domain cycle interval can be replaced by a frequency domain cycle, a frequency domain cycle period, or the like, and the embodiment of the present application does not limit this. The frequency domain cycle interval is taken as an example for illustration.

[0252] As shown in FIG. 5, the frequency domain cycle interval is 12 REs, and (0, 0), (0, 3), (0, 7) are taken as an example of a group of awareness signals, each group of awareness signals cyclically appears in the frequency domain with a cycle of 12 REs.

[0253] By way of example but not limitation, the value of the frequency domain cycle interval is a first integer multiple of the sum of all frequency domain interval values in at least two frequency domain interval values.

[0254] By way of example but not limitation, the value of the frequency domain cycle interval is the sum of all frequency domain interval values in at least two frequency domain interval values.

[0255] For example, in the case where the frequency domain interval includes {3, 4, 5}, the sum of all frequency domain interval values is 12, and then the value of the frequency domain cycle interval can be 12 or a first integer multiple of 12, such as 12, 24, 36, and the like.

[0256] In a possible design of the embodiment, the determining module 1602 is configured to, in the case where the awareness signal configuration information does not include the frequency domain cycle interval, determine that the value of the frequency domain cycle interval is the sum of all frequency domain interval values in at least two frequency domain interval values, the frequency domain cycle interval being used to indicate a cycle of cyclically appearing of the awareness signal in the frequency domain.

[0257] The value of the frequency domain interval is the sum of all the frequency domain interval values in the at least two frequency domain interval values, or is a first integer multiple of the sum of all the frequency domain interval values, which can correspond to the minimum granularity of resource scheduling of the communication system. For example, in the case of a minimum granularity of RB, and one RB containing 12 subcarriers, the frequency domain interval is a first integer multiple of 12, such as 12, 24, 36, etc., which can maintain the same resource scheduling granularity as the communication system, facilitate coordinated scheduling of resources, and avoid resource fragmentation.

[0258] In a possible design of the embodiment, the sensing signal configuration information further includes a frequency domain offset; the frequency domain offset is used to indicate a position of a first sensing signal in the frequency domain interval, an offset compared with a starting position of the frequency domain interval, or is used to indicate an offset of the starting position of the frequency domain interval compared with a first reference point, and the frequency domain interval is used to indicate a period of cyclic occurrence of the sensing signal in the frequency domain.

[0259] By way of example but not limitation, the first reference point includes at least one of the following: an activated frequency domain resource starting point; a starting point of a system bandwidth; a starting point agreed by a communication protocol; a carrier starting point; and a carrier reference point. The first reference point can be a preconfigured point, a predefined point, or any possible form of determined reference point, which is not limited in the embodiment of the present application.

[0260] FIG. 7 shows a schematic diagram of sensing signal configuration provided by an example embodiment of the present application. The frequency domain interval of the sensing signal in FIG. 7 includes {a1, a2, …, a n-1 , with a0 as a frequency domain offset (bias), and P as a frequency domain interval (period) repeatedly occurring in the bandwidth occupied by the sensing signal, where the order of a1, a2, …, a n-1 does not affect the maximum unambiguous distance, and P=a1+a2+…+a n .

[0261] The frequency domain offset a0 in (a) of FIG. 7 indicates a position P1 of a first sensing signal in the frequency domain interval P, compared with an offset of a starting position P0 of the frequency domain interval. The frequency domain offset a0 in (b) of FIG. 7 indicates an offset of the starting position P1 of the frequency domain interval compared with a first reference point P2, and the two indicating manners are essentially equivalent.

[0262] In a possible design of the embodiment, the n frequency domain intervals are co-prime, or there are partially same frequency domain intervals in the n frequency domain intervals, and there are at least two co-prime frequency domain intervals.

[0263] For example, {a1, a2, …, a n-1 are all different values, or a1=a2, and the other frequency domain intervals are different from a1 and a2, which is not limited in the embodiment of the present application.

[0264] In a possible design of the embodiment, the granularity of the frequency domain resource scheduling is N, and P is the first integer multiple of N. For example, the minimum granularity of the scheduling of the 5G system is RB, and one RB contains 12 subcarriers. Therefore, P is the first integer multiple of 12, such as 12, 24, 36, and the like. For another example, the minimum granularity of the reference signal configuration is a subband, and one subband contains 48 subcarriers. Therefore, P is the first integer multiple of 48, such as 48, 96, 144, and the like, which are not limited in the embodiment of the application.

[0265] In a possible design of the embodiment, in the sensing signal configuration information, the frequency domain interval pattern is indicated by a first index or a first value.

[0266] In a possible design of the embodiment, the first index is used to indicate the frequency domain interval pattern in the frequency domain interval pattern pool, and the frequency domain interval pattern pool contains one or more frequency domain interval patterns.

[0267] By way of example but not limitation, the one or more frequency domain interval patterns contained in the frequency domain interval pattern pool include at least one of the following: a first frequency domain interval pattern: 3RE, 4RE, 5RE; a second frequency domain interval pattern: 5RE, 7RE; a third frequency domain interval pattern: 7RE, 8RE, 9RE; and a fourth frequency domain interval pattern: 11RE, 13RE, wherein the resource element is the minimum unit of the frequency domain resource mapping.

[0268] For example, the first frequency domain interval pattern is indicated by the first index with a value of 1, the second frequency domain interval pattern is indicated by the first index with a value of 2, the third frequency domain interval pattern is indicated by the first index with a value of 3, and the fourth frequency domain interval pattern is indicated by the first index with a value of 4.

[0269] The frequency domain interval pattern is obtained from the preset frequency domain interval pattern pool, which can meet the requirements of most common scenarios and reduce the complexity of system design.

[0270] Time domain related information:

[0271] In a possible design of the embodiment, the sensing signal configuration information further includes time domain cycle interval, which is used to indicate the period of the cyclic occurrence of the sensing signal in the time domain.

[0272] The time domain cycle interval can be replaced by the time domain period, the time domain cycle period, and the like, which are not limited in the embodiment of the application. The time domain cycle interval is taken as an example for illustration.

[0273] As shown in FIG. 5, the time domain cycle interval is 10 slots, and (0, 0) and (3, 0) are taken as an example of a group of sensing signals, which cyclically occur in the time domain with a period of 10 slots.

[0274] As an example but not limitation, the value of the time domain cycle interval is a second integer multiple of the sum of all time domain interval values in the at least two time domain interval values.

[0275] As an example but not limitation, the value of the time domain cycle interval is the sum of all time domain interval values in the at least two time domain interval values.

[0276] For example, in the case of time domain intervals including {3, 7}, the sum of all time domain interval values is 10, and the value of the time domain cycle interval can be 10 or a second integer multiple of 10, such as 10, 20, 30, etc.

[0277] In a possible design of the embodiment, the determining module 1602 is configured to determine that the value of the time domain cycle interval is the sum of all time domain interval values in the at least two time domain interval values in the case that the sensing signal configuration information does not include the time domain cycle interval, wherein the time domain cycle interval is used to indicate a period in which the sensing signal cyclically appears in the time domain.

[0278] The value of the time domain cycle interval is the sum of all time domain interval values in the at least two time domain interval values, or a second integer multiple of the sum of all time domain interval values, which can correspond to the minimum granularity of resource scheduling of a communication system. For example, in the case that the minimum granularity is 10 time slots, the time domain cycle interval is a second integer multiple of 10, such as 10, 20, 30, etc., which can maintain the same resource scheduling granularity as the communication system, facilitate coordinated scheduling of resources, and avoid resource fragmentation.

[0279] In a possible design of the embodiment, the sensing signal configuration information further includes a time domain offset, wherein the time domain offset is used to indicate a time domain position of a first sensing signal in the time domain cycle interval, an offset amount compared with a starting position of the time domain cycle interval, or an offset amount of the starting position of the time domain cycle interval compared with a second reference point, and the time domain cycle interval is used to indicate a period in which the sensing signal cyclically appears in the time domain.

[0280] As an example but not limitation, the second reference point includes at least one of the following: a time domain position where the configuration signaling is located; a time domain position where a first reference frame configured by the network is located; and a time domain position where a second reference frame agreed by a communication protocol is located, wherein the time domain position where the configuration signaling is located includes a symbol where the configuration signaling is located or a symbol where the configuration signaling ends. The second reference point can be a reference point determined in any possible form, such as a pre-configured point or a pre-defined point, which is not limited in the embodiment of the application.

[0281] FIG. 8 shows a schematic diagram of sensing signal configuration provided by an example embodiment of the application. As for the frequency domain interval, in the time domain, the time domain interval of the sensing signal includes {b1, b2, …, b m-1}, b0 is a time domain offset (bias), and T is a time domain cycle interval (period) that repeats within the time domain resource occupied by the sensing signal, where T = b1 + b2 + … + b m , and b0 < b1 < b2 < … < bP-1 < bP m .

[0282] The time domain offset b0 in (a) of FIG. 8 refers to the time domain position T1 of the first sensing signal within the time domain cycle interval T, and the offset amount compared with the starting position T0 of the time domain cycle interval. The time domain offset b0 in (b) of FIG. 8 refers to the offset amount of the starting position T1 of the time domain cycle interval compared with the second reference point T2, and the two indications are essentially equivalent.

[0283] In a possible design of the embodiment, assuming that the granularity of the time domain resource scheduling is M, T is a second integer multiple of M. For example, the minimum granularity of the scheduling of the 5G system is a slot, and one slot contains 14 symbols. Then, T is a second integer multiple of 14, such as 14, 28, 42, and the like. For another example, considering that the frame structure is the basis of the entire time domain structure, the minimum granularity of the frame structure can also be referreded to, for example, 10 slots, and then P is a second integer multiple of 10*14 = 140, such as 140, 280, 420, and the like, which is not limited in the embodiment.

[0284] In a possible design of the embodiment, in the sensing signal configuration information, the time domain interval pattern is indicated by a second index or a second value.

[0285] In a possible design of the embodiment, the second index is used to indicate a time domain interval pattern in a time domain interval pattern pool, and the time domain interval pattern pool contains one or more time domain interval patterns.

[0286] By way of example but not limitation, the one or more time domain interval patterns contained in the time domain interval pattern pool include at least one of the following: a first time domain interval pattern: 3 slots, 7 slots; a second time domain interval pattern: 9 slots, 11 slots; a third time domain interval pattern: 5 symbols, 9 symbols; and a fourth time domain interval pattern: 3 symbols, 4 symbols, 7 symbols.

[0287] For example, the first time domain interval pattern is indicated by the second index with a value of 1, the second time domain interval pattern is indicated by the second index with a value of 2, the third time domain interval pattern is indicated by the second index with a value of 3, and the fourth time domain interval pattern is indicated by the second index with a value of 4.

[0288] The time domain interval pattern is obtained from the preset time domain interval pattern pool, which can meet the needs of most common scenarios and reduce the complexity of system design.

[0289] Maximum unambiguous range and maximum unambiguous velocity:

[0290] In a possible design of the present embodiment, the receiving module 1601 is configured to receive a first message; and the first message includes at least one of a maximum unambiguous range of the sensing service and a maximum unambiguous velocity of the sensing service.

[0291] The first message is sent by a sensing service management node, and is used to indicate a sensing service requirement. The sensing service management node can be located in a core network, or at a base station side, or at a terminal side.

[0292] When a pulse emitted by a first sensing signal configuration device (for example, a radar) encounters a backscattering wave generated by a target object at the maximum unambiguous range and returns to the radar, the next pulse is just emitted. That is, the radar wave propagates to the target object located at the maximum unambiguous range, and then the echo returns to the radar in a time interval between two pulses.

[0293] When a maximum pulse phase shift between one pulse and the next pulse that can be measured by the first sensing signal configuration device (for example, the radar) is 180°, a target object radial velocity value corresponding to the 180° pulse phase shift is the maximum unambiguous velocity.

[0294] In a possible design of the present embodiment, the maximum unambiguous velocity can also be a maximum unambiguous Doppler.

[0295] The maximum unambiguous range, the maximum unambiguous distance, and the maximum non-ambiguous range have the same meaning, the maximum unambiguous velocity, the maximum unambiguous speed, and the maximum non-ambiguous speed have the same meaning, and the present embodiment is only exemplified by taking the maximum unambiguous range and the maximum unambiguous velocity.

[0296] In a possible design of the present embodiment, the determining module 1602 is configured to determine a sensing signal configuration based on the first message, and the sending module 1610 is configured to send sensing signal configuration information based on the sensing signal configuration.

[0297] The first sensing signal configuration device determines at least one of a frequency domain interval pattern, a time domain interval pattern, a frequency domain cycle interval, a time domain cycle interval, a frequency domain offset, and a time domain offset based on the first message.

[0298] The present embodiment is exemplified by one receiving module 1601, one determining module 1602, and one sending module 1610, and the number of the receiving module 1601, the determining module 1602, and the sending module 1610 is not limited.

For example, the frequency domain intervals comprise {3, 4, 5, 5, 7}, 3, 4, 5, and 7 are co-prime, and the identical frequency domain interval value is 5.

[0310] In a possible design of the present embodiment, some of the plurality of time domain interval values are co-prime, and some of the plurality of time domain interval values are identical.

The present application does not limit this, and mainly takes the second sensing signal configuration apparatus determining the sensing signal configuration according to the received sensing signal configuration information as an example for description.

[0317] Frequency domain related information:

[0318] In a possible design of the present embodiment, the sensing signal configuration further includes a frequency domain cycle interval, which is used to indicate a period of cyclically appearing of the sensing signal in the frequency domain.

[0320] As shown in FIG. 5, the frequency domain cycle interval is 12 REs, and takes (0, 0), (0, 3), (0, 7) as an example of a group of sensing signals, and each group of sensing signals cyclically appears in the frequency domain with a period of 12 REs.

[0322] By way of example but not limitation, the value of the frequency domain cycle interval is a sum of all frequency domain interval values in at least two frequency domain interval values.

[0323] For example, in the case where the frequency domain interval includes {3, 4, 5}, the sum of all frequency domain interval values is 12, and then the value of the frequency domain cycle interval can be 12, or a first integer multiple of 12, for example, 12, 24, 36, and the like.

[0324] In a possible design of the present embodiment, the determining module 1710 is configured to determine, in the case where the sensing signal configuration does not include the frequency domain cycle interval, that the value of the frequency domain cycle interval is a sum of all frequency domain interval values in at least two frequency domain interval values, and the frequency domain cycle interval is used to indicate a period of cyclically appearing of the sensing signal in the frequency domain.

The second reference point can be a reference point determined in any possible form such as a pre-configured point, a pre-defined point, etc., and the embodiments of the present application do not add any limitation in this regard.

[0344] In a possible design of the present embodiment, in the sensing signal configuration, the time domain interval pattern is represented by the second index or the second value.

[0345] In a possible design of the present embodiment, the second index is used to indicate a time domain interval pattern in a time domain interval pattern pool, and the time domain interval pattern pool contains one or more time domain interval patterns.

[0346] By way of example but not limitation, the one or more time domain interval patterns contained in the time domain interval pattern pool comprise at least one of: a first time domain interval pattern: 3 slots, 7 slots; a second time domain interval pattern: 9 slots, 11 slots; a third time domain interval pattern: 5 symbols, 9 symbols; a fourth time domain interval pattern: 3 symbols, 4 symbols, 7 symbols.

[0347] For example, the first time domain interval pattern is represented by the second index with a value of 1, the second time domain interval pattern is represented by the second index with a value of 2, the third time domain interval pattern is represented by the second index with a value of 3, and the fourth time domain interval pattern is represented by the second index with a value of 4.
