Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a communication method, device and computer-readable storage medium. Background Art

[0002] Communication and perception integration can integrate wireless communication and perception into the same system, and use the propagation characteristics of wireless signals to realize perception functions such as positioning, detection, imaging and identification of targets to obtain information about the surrounding physical environment. For example, the terminal device can send a perception signal, and the network device receives the echo signal of the perception signal, which is the signal generated by the perception signal being reflected by the target in the environment. By receiving the echo signal, the network device estimates the position, speed and other parameters of the target in the environment, thereby obtaining relevant information about the target in the environment.

[0003] However, the resource overhead of the terminal device sending the SRS signal for perception is too large, which is a waste. Therefore, how to reduce the overhead of the terminal device sending the SRS signal for perception is an urgent problem to be solved. Summary of the invention

[0004] Embodiments of the present application provide a communication method, apparatus, and computer-readable storage medium that can reduce the overhead of sending signals.

[0005] In the first aspect, the present application provides a communication method, which can be applied to a terminal device, or to a device in a terminal device (for example, a chip, or a chip system, or a circuit), or a device that can be used in combination with a terminal device. The following description is given by taking the application to a terminal device as an example. The method may include: the terminal device receives first information, the first information is used to indicate at least one of a first resource, a number of resource repetitions associated with the first resource, and whether the first resource is used for sensing, the first resource includes non-continuous time domain symbols in the time domain, the first resource includes comb-shaped resource units in the frequency domain, the resource units included in different time domain symbols of the first resource have different frequency domain offsets, and the first resource is used to transmit a first signal; and the first signal is sent on the first resource.

[0006] In the solution provided in the present application, compared to continuously arranging a large number of time domain symbol resources (for example, 12 consecutive time domain symbol resources) in the time domain, the overhead of sending the first signal can be reduced by indicating at least one of the first resource, the number of resource repetitions associated with the first resource, and whether the first resource is used for perception. Since the first resource includes non-continuous time domain symbols in the time domain, that is, a small number of time domain symbol resources are arranged at intervals in the time domain.

[0007] In one possible implementation, the first resource includes 2 time domain symbols, and the interval between adjacent time domain symbols is 6 symbols or 7 symbols; the first resource includes 2-comb-shaped resource units in the frequency domain, and the offsets of the resource units included in the 2 time domain symbols of the first resource relative to the resource unit numbered 0 are 0 and 1 respectively; or the first resource includes 4-comb-shaped resource units in the frequency domain, and the offsets of the resource units included in the 2 time domain symbols of the first resource relative to the resource unit numbered 0 are 0 and 2 respectively.

[0008] A possible implementation method is that the first resource includes 4 time domain symbols, and the interval between adjacent time domain symbols is 3 symbols; the first resource includes 2-comb-shaped resource units in the frequency domain, and the offsets of the resource units included in the 4 time domain symbols of the first resource relative to the resource unit numbered 0 are 0, 1, 0, 1 respectively; or the first resource includes 4-comb-shaped resource units in the frequency domain, and the offsets of the resource units included in the 4 time domain symbols of the first resource relative to the resource unit numbered 0 are 0, 2, 1, 3 respectively; or the first resource includes 8-comb-shaped resource units in the frequency domain, and the offsets of the resource units included in the 4 time domain symbols of the first resource relative to the resource unit numbered 0 are 0, 4, 2, 6 respectively.

[0009] In a possible implementation, a value of the number of resource repetitions associated with the first resource belongs to a first set, and the first set includes integer values ​​greater than or equal to 12.

[0010] In the embodiment of the present application, by indicating the number of resource repetitions associated with the first resource, the first signal can be repeatedly sent on the first resource, so that the network device can merge the repeatedly sent first signals, improve the signal-to-noise ratio of the received first signal, and then improve the perceived coverage performance when the first signal is used for perception. Secondly, the first set includes integer values ​​greater than or equal to 12. Combined with the maximum number of repetitions and the resource pattern designed in the embodiment of the present application, the number of first signals actually sent in this embodiment can be greater than or equal to the number of first signals sent on the existing 12 consecutive time domain symbols, thereby ensuring that the coverage performance of the resource pattern designed in the embodiment of the present application is not lower than the coverage performance of sending the first signal on 12 consecutive time domain symbols.

[0011] In a possible implementation, the first set consists of 1, 2, 3, 4, 6, and 12.

[0012] In a possible implementation, the first information indicates that the first signal is used for sensing, and phase continuity is maintained when sending the first signal.

[0013] In the solution provided in the present application, the first information indicates that the first signal transmitted on the first resource is used for perception. By arranging a small number of time domain symbol resources at intervals in the time domain and maintaining phase continuity when sending the first signal, the random phase of the signal sent by the radio frequency link can be avoided, resulting in the inability to measure speed.

[0014] In a possible implementation method, the first information indicates at least one of the following: the number of time domain symbols of the first resource, the comb tooth size, the time domain symbol interval, the position information of a time domain symbol in the time domain symbols included in the first resource, and the frequency domain offset information of the resource units included in different time domain symbols.

[0015] In a possible implementation manner, there is a corresponding relationship between the number of time domain symbols of the first resource, the comb tooth size, and the frequency domain offset information of the resource units included in different time domain symbols.

[0016] In a possible implementation manner, the first signal is a sounding reference signal or a positioning sounding reference signal.

[0017] In a possible implementation manner, the first signal is used for sensing, or for sensing and channel measurement, or for sensing and channel estimation, or for sensing and positioning.

[0018] In the second aspect, the present application provides a communication method, which can be applied to a network device, or to a device in a network device (for example, a chip, or a chip system, or a circuit), or a device that can be used in combination with a network device. The following description is given by taking the application to a network device as an example. The method may include: sending first information, the first information being used to indicate at least one of a first resource, a number of resource repetitions associated with the first resource, and whether the first resource is used for sensing, the first resource including non-continuous time domain symbols in the time domain, the first resource including comb-shaped resource units in the frequency domain, different time domain symbols of the first resource including resource units having different frequency domain offsets, and the first resource being used to transmit a first signal; receiving a first signal on the first resource.

[0057] The following is a description of the technical terms that may appear in the embodiments of the present application. The terms used in the implementation mode of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application. In the various embodiments of the present application, if there is no special explanation and logical conflict, the terms and / or descriptions between different embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0058] (1) Perception

[0059] Perception is the detection of parameters of targets in the physical environment, such as the position of the target, the speed of the target, etc. It can be understood that a radar detection system detects the target by emitting electromagnetic waves and analyzing the echo signal reflected from the target. Perception can also be called detection.

[0060] (2) Perception Signal

[0061] A signal used to sense (or detect) a sensed target (or target object). The sensing signal is also called a detection signal, a linear frequency modulation signal, a radar signal, a radar sensing signal, a radar detection signal, an environmental sensing signal, etc. The sensing signal can be a pulse signal or a signal in a wireless communication system. For example, the sensing signal can be an orthogonal frequency division multiplexing (OFDM) signal obtained by modulating a specific sequence on a subcarrier, and the specific sequence can be any one of the following sequences: a Zadoff-Chu sequence (abbreviated as ZC sequence), a pseudo-random sequence, a predefined sequence, etc. Among them, the pseudo-random sequence includes any one of the following sequences: the longest linear feedback shift register sequence (abbreviated as m sequence), a Gold sequence, etc. The predefined sequence can be, for example, a random data symbol, for example, a random data symbol modulated by quadrature phase shift keying (QPSK), 16 quadrature amplitude modulation (QAM), etc.

[0062] (3) Communication perception fusion signal

[0063] It can also be called a synaesthesia fusion signal, which is a signal used for both communication and perception. The signal used for communication can be understood as carrying communication data or a communication reference signal sequence that needs to be transmitted between communication devices.

[0064] (4) Communication and perception integration

[0065] Communication and perception integration aims to integrate wireless communication and perception into the same system, and use the various propagation characteristics of wireless signals to achieve perception functions such as positioning, detection, imaging and identification of targets, so as to obtain information about the surrounding physical environment, tap into communication capabilities, and enhance user experience. For example, the terminal device can send a perception signal, and the network device receives the echo signal of the perception signal, which is the signal generated by the perception signal being reflected by the target in the environment. By receiving the echo signal, the network device estimates the position, speed and other parameters of the target in the environment and obtains relevant information about the target in the environment.

[0066] (5) Sounding reference signal (SRS)

[0067] The sounding reference signal is a reference signal used for uplink channel measurement. The sounding reference signal can be mainly used for uplink channel measurement. Based on the sounding reference signal measurement results, the system can perform time-frequency resource scheduling, link adaptation, large-scale multiple-input multiple-output (MIMO), etc. The sounding reference signal can also be used for beam management, including beam training, beam switching, etc. In addition, for time division duplex (TDD) systems, the reciprocity of the uplink and downlink channels can also be used to obtain the channel state information of the downlink channel through the sounding reference signal. In addition, the sounding reference signal can also be used for positioning. The network equipment can estimate the user's location based on the sounding reference signal sent by the user.

[0068] It should be understood that the description of the above technical terms is only for example. For example, with the continuous development of technology, the scope of the above definitions may also change, and the embodiments of this application are not limited thereto.

[0069] The following is an example description of a network architecture applicable to the embodiments of the present application.

[0072] like Figure 1As shown, the network device and the terminal devices 1 to 6 form a communication system, in which the network device sends downlink data to one or more of the terminal devices 1 to 6, and the terminal devices 1 to 6 can also send uplink data to the network device. In addition, aggregate transmission can be performed between the terminal devices, such as the terminal devices 4 to 6 shown in the figure.

It may be a macro base station, a micro base station or an indoor station, a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, it may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the network device in the vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the network device in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform). The network device in this application may also be a logical node, a logical module or software that can implement all or part of the network device functions.

[0075] The network device in the embodiment of the present application may be a device in a wireless network, such as a radio access network (RAN) node that connects a terminal device to a wireless network. In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node may be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU may be separately configured, or may be included in the same network element, such as a baseband unit (BBU). The RU may be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). In different systems, CU (or CU-CP and CU-UP), DU, or RU may also have different names, but those skilled in the art may understand their meanings. For example, in an open radio access network (ORAN) system, CU may also be referred to as O-CU (open CU), DU may also be referred to as O-DU, CU-CP may also be referred to as O-CU-CP, CU-UP may also be referred to as O-CU-UP, and RU may also be referred to as O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit in the CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0076] The network device in the present application may also be a device with a sensing function, which can receive and process signals reflected by targets in the environment. The target may be various tangible objects in the environment that can reflect electromagnetic waves, such as mountains, forests, or buildings, and may also include movable objects such as vehicles, drones, pedestrians, and terminal devices. The target may also be referred to as a sensed target, a detected target, a sensed object, a detected object, or a sensed device, etc., which is not limited in the embodiments of the present application.

[0077] In the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem including the network device function. The control subsystem including the network device function here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or by a device including the terminal device function.

[0078] In this application, the network device sends a downlink signal or downlink information to the terminal device, and the downlink information is carried on the downlink channel; the terminal device sends an uplink signal or uplink information to the network device, and the uplink information is carried on the uplink channel. In order to communicate with the network device, the terminal device needs to establish a wireless connection with the cell controlled by the network device. The cell with which the terminal device has established a wireless connection is called the service cell of the terminal. When the terminal device communicates with the service cell, it will also be interfered by the signal from the neighboring cell.

[0079] In the embodiments of the present application, the time domain symbol may be an orthogonal frequency division multiplexing (OFDM) symbol or a discrete Fourier transform spread OFDM (DFT-s-OFDM) symbol. Unless otherwise specified, the symbols in the embodiments of the present application refer to time domain symbols.

[0080] See also Figure 2 , Figure 2 Schematic diagram of a perception scenario provided by an embodiment of the present application. In a possible implementation, the terminal device can send a perception signal, and the network device receives an echo signal of the perception signal to achieve perception. For example, Figure 2 As shown in (a), the terminal device sends a perception signal, and the network device receives the echo signal generated by the perception signal reflecting from the target in the environment, thereby sensing the target's position, speed and other information.

[0081] It should be noted that when a network device receives an echo signal of a perception signal sent by a terminal device, it can also simultaneously receive a communication signal or a perception signal sent by other terminal devices in a frequency division multiplexing, space division multiplexing, etc. manner, such as Figure 2 As shown in (b), the network device not only receives the echo signal of the perception signal sent by terminal device A, but also receives the communication signal sent by other terminal devices (such as terminal device B) at the same time.

[0082] In order to facilitate the understanding of the embodiments of the present application, the technical problems to be specifically solved by the present application are further analyzed and proposed.

[0083] The terminal device can send a detection reference signal, and the network device receives the echo signal of the detection reference signal reflected by the target in the environment for perception. In a possible implementation, the detection reference signal can also be used for positioning. Figure 3 , Figure 3 FIG. 1 is a schematic diagram of a resource of a sounding reference signal for positioning provided in an embodiment of the present application. Figure 3 As shown, the resources of the sounding reference signal used for positioning may include 1, 2, 4, 8 or 12 consecutive time domain symbols in the time domain, and the period of the resources is at least 1 time slot. Taking 12 consecutive time domain symbols as an example, assuming that on the mth time domain symbol, the signal sent by the transmitter is Where j represents the imaginary unit, φ m represents the phase value of the mth time domain symbol (which can also be understood as the initial phase), s m (t) represents the baseband signal of the mth time domain symbol, and m is an integer greater than or equal to 1 and less than or equal to 12. After being reflected by a target in the environment, the echo signal received by the receiving end is Where τ represents the delay of the echo signal relative to the sensing signal, T represents the signal transmission period (interval), and f d It represents the Doppler frequency shift caused by target movement, and A represents the amplitude attenuation of the echo signal relative to the transmitted signal (affected by the target's reflection ability and path loss). During perception processing, by measuring and estimating the time delay of the echo signal relative to the transmitted signal, the distance to the target can be estimated to achieve the ranging function; by measuring and estimating the phase relationship of multiple echo signals in time, the Doppler frequency shift of the target can be estimated to achieve the speed measurement function.

[0084] When using the detection reference signal for positioning and sensing, the following problems may occur:

[0085] 1. The perceived speed measurement range is determined by the signal transmission cycle, and the maximum speed measurement range is Where T represents the signal transmission period, λ t Indicates the wavelength of the transmitted signal. For perception, the signal is reflected by the target and the signal energy is lost a lot, so it is necessary to send the signal multiple times for accumulation, such as 12 consecutive time domain symbols. When using the detection reference signal resource of 12 consecutive time domain symbols for perception, for example, when the subcarrier spacing is 120kHz and the carrier frequency is 28GHz, the signal transmission period is the time length of 1 time domain symbol. It can be calculated that the speed measurement range using this resource is as high as 925km / h, while the speed measurement range requirement of the normal perception scenario will not exceed 200km / h. In fact, the signal transmission period of this resource is too short, resulting in excessive waste of the number of time domain symbols included in this resource, which leads to a large overhead of sending signals.

[0086] 2. The detection reference signal used for positioning requires distance measurement but not speed measurement, that is, it only needs to estimate the relative delay between the transmitted signal and the received signal, and does not need to estimate the Doppler frequency shift (calculated by the phase difference between multiple received signals). The phase values ​​of the detection reference signal sent on different time domain symbols may be randomly generated, that is, φ m Randomly generated, this will cause the network equipment to be unable to estimate the Doppler frequency shift from the multiple received signals, and thus unable to measure the speed.

[0087] Therefore, the technical problems that can be solved by the embodiments of the present application include: 1. How to reduce the overhead of sending signals; 2. How to enable network equipment to measure speed based on received signals.

[0088] The specific embodiments will be described below. It should be understood that the perception and communication integration may change with the evolution of the technical solution, and the technical solution provided by this application is not limited to the process described below. Furthermore, the description of the scene in the embodiment of this application is only an example, and does not limit the solution of the embodiment of this application to be used only in the description scene, and is also applicable to scenes with similar problems.

[0089] The following describes a communication method provided in an embodiment of the present application. Figure 4 , Figure 4 is an interactive schematic diagram of a communication method provided in an embodiment of the present application. The terminal device in the embodiment of the present application may be Figure 1 The terminal device in the network architecture shown in the figure, the functions performed by the terminal device in this embodiment can also be performed by a device in the terminal device (for example, a chip, or a chip system, or a circuit). The network device in this embodiment can be Figure 1 The network device in the network architecture shown in the figure, the functions performed by the network device in this embodiment can also be performed by a device (for example, a chip, or a chip system, or a circuit) in the network device. Figure 4 As shown, the communication method may include the following steps.

[0090] S401: The network device sends first information to the terminal device, where the first information is used to indicate at least one of a first resource, a resource repetition number associated with the first resource, and whether the first resource is used for sensing. Accordingly, the terminal device receives the first information from the network device.

[0091] The first information is used to indicate at least one of a first resource, a number of resource repetitions associated with the first resource, and whether the first resource is used for sensing, and the first resource can be used to transmit a first signal.

[0092] The first signal may be a sounding reference signal (SRS) or a positioning sounding reference signal (SRS for positioning, SRS-pos), or may be a reference signal, a demodulation reference signal, or other signals, such as a physical uplink shared channel (PUSCH) signal, etc., which is not limited in the embodiments of the present application. The first signal may be used for sensing, or for sensing and channel measurement, or for sensing and channel estimation, or for sensing and positioning.

[0093] The first resource may include non-continuous time domain symbols in the time domain. The non-continuous time domain symbols may refer to that an absolute value of a difference between numbers of any two adjacent time domain symbols included in the first resource in the time domain is greater than 1.

[0094] The first resource includes comb-shaped resource elements (REs) in the frequency domain, wherein the comb shape can be understood as that the absolute value of the difference between the numbers of any two adjacent REs included in the REs on any time domain symbol included in the first resource is C, and C is an integer greater than or equal to 2, and C represents the comb tooth size. Alternatively, the first resource includes equally spaced REs in the frequency domain, and the comb tooth size C is the spacing between two adjacent REs. For example, a 2-point comb shape means that the comb tooth size C=2, that is, the first resource occupies the frequency domain resources in the form of a 2-point comb on any time domain symbol included in it, that is, 1 RE is occupied in every 2 REs and the occupied REs occupy the same relative position in every 2 REs, or 1 RE is occupied every other 1 RE, or the absolute value of the difference between the numbers of any two adjacent REs included in the REs on any time domain symbol included in the first resource is 2. For another example, a 4-point comb shape means a comb tooth size C=4, that is, the first resource occupies frequency domain resources in a 4-point comb shape on any time domain symbol included therein, that is, 1 RE is occupied in every 4 REs and the occupied REs occupy the same relative position in every 4 REs, or 1 RE is occupied every 3 REs, or the absolute value of the difference between the numbers of any two adjacent REs in the REs included in any time domain symbol included therein by the first resource is 4. The comb tooth size (size) may also be referred to as comb tooth width or comb tooth size, etc. For example, a comb tooth size of 2 may also be understood as the first resource including 2-point comb-shaped REs in the frequency domain, a comb tooth size of 4 may also be understood as the first resource including 4-point comb-shaped REs in the frequency domain, a comb tooth size of 8 may also be understood as the first resource including 8-point comb-shaped REs in the frequency domain, etc.

[0095] The frequency domain offsets of REs included in different time domain symbols of the first resource are different. In a possible implementation, the first resource includes M non-continuous time domain symbols in the time domain, and the RE number occupied by the first resource in the time domain symbol m is C×n+o m , where time domain symbol m refers to the mth time domain symbol among M non-continuous time domain symbols, C is the comb tooth size, n is an integer greater than or equal to 0, o m is the frequency domain offset associated with the time domain symbol m, M is an integer greater than or equal to 2, m is an integer greater than or equal to 1 and less than or equal to M, o m is an integer greater than or equal to 0, and the M time domain symbols are associated with o m Not exactly the same.

[0096] Exemplarily, M=2, the comb tooth size C=2, the frequency domain offsets of the REs included in the first time domain symbol and the second time domain symbol of the first resource are 0 and 1 respectively, that is, o1=0, o2=1, that is, the first resource includes two time domain symbols, wherein the REs included in the first time domain symbol of the first resource are numbered C×n+o1(2×n+0), that is, 0, 2, 4, 6, 8, 10,…; the resource units included in the second time domain symbol of the first resource are numbered C×n+o2(2×n+1), that is, 1, 3, 5, 7, 9, 11,…

[0097] The first information may indicate (include) at least one of the following: the number of time domain symbols of the first resource, the comb tooth size, the time domain symbol interval, the position information of a time domain symbol in the time domain symbols included in the first resource, and the frequency domain offset information of REs included in different time domain symbols. Among them, the position information of a time domain symbol in the time domain symbols included in the first resource may be the position information of the first time domain symbol or the position information of the last time domain symbol. The frequency domain offset information of REs included in different time domain symbols may be the frequency domain starting offset information of REs included in different time domain symbols, for example, it may be the offset information of REs included in different time domain symbols relative to the starting RE (for example, RE numbered 0).

[0098] In a possible implementation, there is a correspondence between the number of time domain symbols of the first resource, the comb tooth size, and the frequency domain offset information of the RE included in different time domain symbols. The correspondence can be presented in a tabular form, or the correspondence can be predefined by the protocol so that both the network device and the terminal device are known. Table 1 is exemplified in a tabular form.

[0099] Table 1 Correspondence between the number of time domain symbols of the first resource, the comb tooth size, and the frequency domain offset information of REs included in different time domain symbols

[0100] The number of time domain symbols of the first resource is 2 The number of time domain symbols of the first resource is 4 Comb size is 2 0,1 0,1,0,1 Comb size is 4 0,2 0,2,1,3, Comb size is 8 --- 0,4,2,6

[0101] As shown in Table 1, the frequency domain offsets of REs included in different time domain symbols can be represented by multiple numbers. For example, if the comb tooth size C=2, the first resource includes 2 non-continuous time domain symbols in the time domain, that is, M=2, and the frequency domain offsets of REs included in the first time domain symbol and the second time domain symbol of the first resource are 0 and 1, respectively, that is, o1=0, o2=1; if the comb tooth size C=2, the first resource includes 4 non-continuous time domain symbols in the time domain, that is, M=4, and the frequency domain offsets of REs included in the first time domain symbol, the second time domain symbol, the third time domain symbol and the fourth time domain symbol of the first resource are 0, 1, 0, 1, respectively, that is, o1=0, o2=1, o3=0, o4=1; if the comb tooth size C=4, the first resource includes 2 non-continuous time domain symbols in the time domain, the first time domain symbol and the second time domain symbol of the first resource are The frequency domain offsets of RE included in the symbol are 0 and 2 respectively, that is, o1=0, o2=2; if the comb tooth size C=4, the first resource includes 4 non-continuous time domain symbols in the time domain, and the frequency domain offsets of RE included in the first time domain symbol, the second time domain symbol, the third time domain symbol and the fourth time domain symbol of the first resource are 0, 2, 1, and 3 respectively, that is, o1=0, o2=2, o3=1, and o4=3; if the comb tooth size C=8, the first resource includes 4 non-continuous time domain symbols in the time domain, and the frequency domain offsets of RE included in the first time domain symbol, the second time domain symbol, the third time domain symbol and the fourth time domain symbol of the first resource are 0, 4, 2, and 6 respectively, that is, o1=0, o2=4, o3=2, and o4=6.

[0102] When there is a corresponding relationship among the number of time domain symbols of the first resource, the comb tooth size, and the frequency domain offset information of REs included in different time domain symbols, the first information may only indicate the number of time domain symbols and the comb tooth size of the first resource. After receiving the first information, the terminal device can determine the frequency domain offset information of REs included in different time domain symbols of the first resource based on the number of time domain symbols of the first resource, the comb tooth size, and the corresponding relationship, thereby saving the signaling overhead of the first information.

[0103] Exemplarily, according to the number of time-domain symbols and comb tooth sizes of the first resource, several pattern designs of the first resource are given below.

[0104] In a first possible embodiment, the comb tooth size C of the first resource in the frequency domain is 2, and the first resource includes 2 non-continuous time domain symbols in the time domain, that is, M=2. Figure 5 , Figure 5 This is a schematic diagram of a pattern of a first resource provided in an embodiment of the present application.

[0105] like Figure 5As shown in (a), one time slot includes 12 time domain symbols, and the first resource includes 2 non-continuous time domain symbols in the time domain, that is, M=2. The interval between adjacent time domain symbols is 6 symbols, that is, the interval between the first time domain symbol and the second time domain symbol of the first resource is 6 symbols. For example, the first time domain symbol is numbered 2, and the interval between the first time domain symbol and the second time domain symbol is 6 symbols, that is, the second time domain symbol is numbered 2+6=8. The comb tooth size C=2, the offsets of the REs included in the first time domain symbol and the second time domain symbol of the first resource relative to the RE numbered 0 are 0 and 1, respectively, that is, o1=0, o2=1. For example, the REs included in the first time domain symbol of the first resource are numbered 0, 2, 4, 6, 8, 10, and the REs included in the second time domain symbol of the first resource are numbered 1, 3, 5, 7, 9, 11. Exemplarily, for Figure 5 The pattern of the first resource shown in (a) may include information that the number of time domain symbols of the first resource is 2, the comb tooth size is 2, the interval between adjacent time domain symbols is 6, the time domain position of the last symbol is 3 time domain symbols away from the last time domain symbol in the time slot (the 4th to last time domain symbol in the time slot, i.e., numbered 8), and the frequency domain offsets of REs included in different time domain symbols are 0 and 1, respectively.

[0106] like Figure 5 As shown in (b), one time slot includes 14 time domain symbols, and the first resource includes 2 non-continuous time domain symbols in the time domain, that is, M=2. The interval between adjacent time domain symbols is 7 symbols, that is, the interval between the first time domain symbol and the second time domain symbol of the first resource is 7 time domain symbols. For example, the first time domain symbol is numbered 2, and the interval between the first time domain symbol and the second time domain symbol is 7 symbols, that is, the second time domain symbol is numbered 2+7=9. The comb tooth size C=2, and the offsets of the REs included in the first time domain symbol and the second time domain symbol of the first resource relative to the RE numbered 0 are 0 and 1, respectively, that is, o1=0, o2=1. For example, the REs included in the first time domain symbol of the first resource are numbered 0, 2, 4, 6, 8, 10, and the REs included in the second time domain symbol of the first resource are numbered 1, 3, 5, 7, 9, 11. Exemplarily, for Figure 5 The pattern of the first resource shown in (b) may include information that the number of time domain symbols of the first resource is 2, the comb tooth size is 2, the interval between adjacent time domain symbols is 7, the time domain position of the last symbol is 4 time domain symbols away from the last time domain symbol in the time slot (the fifth to last time domain symbol in the time slot, i.e., numbered 9), and the frequency domain offsets of REs included in different time domain symbols are 0 and 1, respectively.

[0107] In a second possible embodiment, the comb tooth size C of the first resource in the frequency domain is 4, and the first resource includes 2 non-continuous time domain symbols in the time domain, that is, M=2. Figure 6 , Figure 6 It is a schematic diagram of another pattern of a first resource provided in an embodiment of the present application.

[0108] like Figure 6 As shown in (a), one time slot includes 12 time domain symbols, and the first resource includes 2 non-continuous time domain symbols in the time domain, that is, M=2. The interval between adjacent time domain symbols is 6 symbols, that is, the interval between the first time domain symbol and the second time domain symbol of the first resource is 6 symbols. For example, the first time domain symbol is numbered 2, and the interval between the first time domain symbol and the second time domain symbol is 6 symbols, that is, the second time domain symbol is numbered 2+6=8. The comb tooth size C=4, the offsets of the REs included in the first time domain symbol and the second time domain symbol of the first resource relative to the RE numbered 0 are 0 and 2, respectively, that is, o1=0, o2=2. For example, the REs included in the first time domain symbol of the first resource are numbered 0, 4, 8, and the resource units included in the second time domain symbol of the first resource are numbered 2, 6, 10. Exemplarily, for Figure 6 The pattern of the first resource shown in (a) may include information that the number of time domain symbols of the first resource is 2, the comb tooth size is 4, the interval between adjacent time domain symbols is 6, the time domain position of the last symbol is 3 time domain symbols away from the last time domain symbol in the time slot (the 4th to last time domain symbol in the time slot, i.e., numbered 8), and the frequency domain offsets of REs included in different time domain symbols are 0 and 2, respectively.

[0109] like Figure 6 As shown in (b), one time slot includes 14 time domain symbols, and the first resource includes 2 non-continuous time domain symbols in the time domain, that is, M=2. The interval between adjacent time domain symbols is 7 symbols, that is, the interval between the first time domain symbol and the second time domain symbol of the first resource is 7 time domain symbols. For example, the first time domain symbol is numbered 2, and the interval between the first time domain symbol and the second time domain symbol is 7 symbols, that is, the second time domain symbol is numbered 2+7=9. The comb tooth size C=4, the offsets of the REs included in the first time domain symbol and the second time domain symbol of the first resource relative to the RE numbered 0 are 0 and 2, respectively, that is, o1=0, o2=2. For example, the REs included in the first time domain symbol of the first resource are numbered 0, 4, 8, and the REs included in the second time domain symbol of the first resource are numbered 2, 6, 10. Exemplarily, for Figure 6The pattern of the first resource shown in (b) may include information that the number of time domain symbols of the first resource is 2, the comb tooth size is 4, the interval between adjacent time domain symbols is 7, the time domain position of the last symbol is 4 time domain symbols away from the last time domain symbol in the time slot (the fifth to last time domain symbol in the time slot, i.e., numbered 9), and the frequency domain offsets of REs included in different time domain symbols are 0 and 2 respectively.

[0110] In a third possible embodiment, the comb tooth size C of the first resource in the frequency domain is 2, and the first resource includes 4 non-continuous time domain symbols in the time domain, that is, M=4. Figure 7 , Figure 7 FIG. 1 is a schematic diagram of another first resource provided in an embodiment of the present application. Figure 7 As shown, one time slot includes 12 time domain symbols, and the interval between adjacent time domain symbols is 3 symbols, that is, the interval between the first time domain symbol and the second time domain symbol, the second time domain symbol and the third time domain symbol, and the third time domain symbol and the fourth time domain symbol of the first resource is 3 symbols, which can be understood as the interval between two adjacent time domain symbols in the 4 non-continuous time domain symbols is 3 time domain symbols. For example, the first time domain symbol is numbered 2, the interval between the first time domain symbol and the second time domain symbol is 3 symbols, that is, the second time domain symbol is numbered 2+3=5, the interval between the second time domain symbol and the third time domain symbol is 3 symbols, that is, the third time domain symbol is numbered 5+3=8, the interval between the third time domain symbol and the fourth time domain symbol is 3 symbols, that is, the fourth time domain symbol is numbered 8+3=11. The comb tooth size C=2, and the offsets of the REs included in the first time domain symbol, the second time domain symbol, the third time domain symbol, and the fourth time domain symbol of the first resource relative to the RE numbered 0 are 0, 1, 0, 1, respectively, that is, o1=0, o2=1, o3=0, o4=1. For example, the REs included in the first time domain symbol of the first resource are numbered 0, 2, 4, 6, 8, 10, the REs included in the second time domain symbol of the first resource are numbered 1, 3, 5, 7, 9, 11, the REs included in the third time domain symbol of the first resource are numbered 0, 2, 4, 6, 8, 10, and the REs included in the fourth time domain symbol of the first resource are numbered 1, 3, 5, 7, 9, 11. Exemplarily, for Figure 7 The pattern of the first resource shown, the first information may indicate that the number of time domain symbols of the first resource is 4, the comb tooth size is 2, the interval between adjacent time domain symbols is 3, the time domain position of the last symbol is 0 time domain symbols away from the last time domain symbol in the time slot (the last time domain symbol in the time slot, i.e., numbered 11), and the frequency domain offsets of REs included in different time domain symbols are 0, 1, 0, 1 respectively.

[0111] In a fourth possible embodiment, the comb tooth size C of the first resource in the frequency domain is 4, and the first resource includes 4 non-continuous time domain symbols in the time domain, that is, M=4. Figure 8 , Figure 8 FIG. 1 is a schematic diagram of another first resource provided in an embodiment of the present application. Figure 8 As shown, one time slot includes 12 time domain symbols, and the interval between adjacent time domain symbols is 3 symbols, that is, the interval between the first time domain symbol and the second time domain symbol, the second time domain symbol and the third time domain symbol, and the third time domain symbol and the fourth time domain symbol of the first resource is 3 symbols, which can be understood as the interval between two adjacent time domain symbols in the 4 non-continuous time domain symbols is 3 time domain symbols. For example, the first time domain symbol is numbered 2, the interval between the first time domain symbol and the second time domain symbol is 3 symbols, that is, the second time domain symbol is numbered 2+3=5, the interval between the second time domain symbol and the third time domain symbol is 3 symbols, that is, the third time domain symbol is numbered 5+3=8, the interval between the third time domain symbol and the fourth time domain symbol is 3 symbols, that is, the fourth time domain symbol is numbered 8+3=11. The comb tooth size C=4, and the offsets of the REs included in the first time domain symbol, the second time domain symbol, the third time domain symbol, and the fourth time domain symbol of the first resource relative to the RE numbered 0 are 0, 2, 1, and 3, respectively, that is, o1=0, o2=2, o3=1, and o4=3. For example, the REs included in the first time domain symbol of the first resource are numbered 0, 4, and 8, the REs included in the second time domain symbol of the first resource are numbered 2, 6, and 10, the REs included in the third time domain symbol of the first resource are numbered 1, 5, and 9, and the REs included in the fourth time domain symbol of the first resource are numbered 3, 7, and 11. Exemplarily, for Figure 8 The pattern of the first resource shown, the first information may indicate that the number of time domain symbols of the first resource is 4, the comb tooth size is 4, the interval between adjacent time domain symbols is 3, the time domain position of the last symbol is 0 time domain symbols away from the last time domain symbol in the time slot (the last time domain symbol in the time slot, i.e., numbered 11), and the frequency domain offsets of REs included in different time domain symbols are 0, 2, 1, and 3, respectively.

[0112] In a fifth possible embodiment, the comb tooth size C of the first resource in the frequency domain is 8, and the first resource includes 4 non-continuous time domain symbols in the time domain, that is, M=4. Fig. 9 , Fig. 9 FIG. 1 is a schematic diagram of another first resource provided in an embodiment of the present application. Fig. 9As shown, one time slot includes 12 time domain symbols, and the interval between adjacent time domain symbols is 3 symbols, that is, the interval between the first time domain symbol and the second time domain symbol, the second time domain symbol and the third time domain symbol, and the third time domain symbol and the fourth time domain symbol of the first resource is 3 symbols, which can be understood as the interval between two adjacent time domain symbols in the 4 non-continuous time domain symbols is 3 time domain symbols. For example, the first time domain symbol is numbered 2, the interval between the first time domain symbol and the second time domain symbol is 3 symbols, that is, the second time domain symbol is numbered 2+3=5, the interval between the second time domain symbol and the third time domain symbol is 3 symbols, that is, the third time domain symbol is numbered 5+3=8, the interval between the third time domain symbol and the fourth time domain symbol is 3 symbols, that is, the fourth time domain symbol is numbered 8+3=11. The comb tooth size C=8, and the offsets of the REs included in the first time domain symbol, the second time domain symbol, the third time domain symbol, and the fourth time domain symbol of the first resource relative to the RE numbered 0 are 0, 4, 2, and 6, respectively, that is, o1=0, o2=4, o3=2, and o4=6. For example, the REs included in the first time domain symbol of the first resource are numbered 0 and 8, the REs included in the second time domain symbol of the first resource are numbered 4, the REs included in the third time domain symbol of the first resource are numbered 2 and 10, and the REs included in the fourth time domain symbol of the first resource are numbered 6. Exemplarily, for Fig. 9 The pattern of the first resource shown, the first information may indicate that the number of time domain symbols of the first resource is 4, the comb tooth size is 8, the interval between adjacent time domain symbols is 3, the time domain position of the last symbol is 0 time domain symbols away from the last time domain symbol in the time slot (the last time domain symbol in the time slot, i.e., numbered 11), and the frequency domain offsets of REs included in different time domain symbols are 0, 4, 2, and 6, respectively.

[0113] It can be seen from the above-mentioned embodiments that compared to continuously arranging a large number of time domain symbol resources in the time domain (for example, 12 consecutive time domain symbol resources), since the first resource includes non-continuous time domain symbols in the time domain, that is, by arranging a small number of time domain symbol resources at intervals in the time domain, the overhead of sending the first signal can be reduced.

[0114] The first information may indicate whether the first signal transmitted on the first resource is used for perception. For example, 1 bit may be used to indicate whether the first signal is used for perception, 0 indicates not used for perception, and 1 indicates used for perception. By sending information indicating whether the first signal is used for perception to the terminal device, the network device can enable the terminal device to determine whether the first signal sent on the first resource is used for perception. In one possible implementation, the first information indicates that the first signal transmitted on the first resource is used for perception, and the overhead of sending the first signal for perception can be reduced by arranging a small number of time domain symbol resources at intervals in the time domain. Optionally, the first information may also indicate that the first signal is used for perception and channel measurement, or for perception and channel estimation, or for perception and positioning, etc., to inform the terminal device of the function of the first signal.

[0115] In a possible implementation, the first information indicates that the first signal transmitted on the first resource is used for perception, and the terminal device maintains phase continuity when sending the first signal. It can be understood that the terminal device maintains phase continuity in the time period where the first resource is located, and it can also be understood that the absolute value of the difference between the phase values ​​of the signals sent by the terminal device in different time units in the time period where the first resource is located is less than a certain threshold, and the phase value can also be understood as the initial phase. It can also be understood that the difference between the phase values ​​of time slot p and time slot p-1 of the first device in the first time period is less than the first value, or the difference between the phase values ​​of time slot p and time slot 0 in the first time period is less than the second value, where p is an integer greater than or equal to 1. It can be understood that the first value and the second value can be a predefined value or a value notified by the network device through signaling. The first value and the second value can be the same or different. The embodiment of the present application does not limit the specific numerical values ​​of the first value and the second value. Since the phase values ​​of the first signal sent are the same, it can be avoided that the random phase of the signal sent by the radio frequency link can prevent the speed from being measured, and the speed measurement used in perception can be achieved.

[0116] The first information may indicate the number of resource repetitions associated with the first resource. For example, the first information may indicate that the number of resource repetitions associated with the first resource is 2, then the terminal device may send the first signal with the first resource and the same spatial filter on two adjacent uplink time slots. The value of the number of resource repetitions belongs to the first set. In a possible implementation, the first set includes integer values ​​greater than or equal to 12, or the first set includes integer values ​​greater than or equal to 6, or the first set includes integer values ​​greater than or equal to 3. For example, the first set consists of 1, 2, 3, 4, 6, 12; for another example, the first set consists of at least 2 of 1, 2, 3, 4, 6, 12.

[0117] Among them, the number of resource repetitions may be related to the number of time domain symbols of the first resource, for example, if the number of time domain symbols of the first resource is 1, the first set may include an integer value greater than or equal to 12, or if the number of time domain symbols of the first resource is 2, the first set may include an integer value greater than or equal to 6, or if the number of time domain symbols of the first resource is 4, the first set may include an integer value greater than or equal to 3. By indicating the number of resource repetitions associated with the first resource, the first signal can be sent repeatedly on the first resource, so that the network device can merge the repeatedly sent first signal, improve the signal-to-noise ratio of the received first signal, and thus improve the perceived coverage performance when the first signal is perceived. Secondly, the number of resource repetitions included in the first set is a factor of 12. Combined with the maximum number of repetitions and the resource pattern designed in the embodiment of the present application, the number of first signals actually sent in the present embodiment can be greater than or equal to the number of first signals sent on the existing 12 consecutive time domain symbols, thereby ensuring that the coverage performance of the resource pattern designed in the embodiment of the present application is not lower than the coverage performance of sending the first signal on 12 consecutive time domain symbols.

[0118] Optionally, the first information may also indicate a period for sending the first signal. For example, the first signal may be sent Y times (Y is an integer greater than or equal to 1) repeatedly using the same spatial filter in each period with X time slots (X is an integer greater than or equal to 1). For example, the first signal may be repeatedly sent once in each cycle with 10 time slots as a cycle, such as sending the first signal once in the 1st time slot in the first cycle (such as the 1st to 10th time slots), sending the first signal once in the 11th time slot in the second cycle (the 11th to 20th time slots), and so on; for example, the first signal may be repeatedly sent three times in each cycle with the same spatial filter with 10 consecutive time slots as a cycle, such as sending the first signal in the 1st to 3rd time slots (a total of 3 time slots) in the first cycle (such as the 1st to 10th time slots) with the same spatial filter, sending the first signal in the 11th to 13th time slots (a total of 3 time slots) in the second cycle (the 11th to 20th time slots) with the same spatial filter, and so on.

[0119] Optionally, an example is given below in which a network device indicates a first resource through first information. For example, the first information includes information indicating at least one resource set, wherein any resource set includes at least one first resource. The following description is given by taking the first signal as an SRS signal as an example.

[0120] Assume that the first information includes information indicating a first resource set, wherein the first resource set includes SRS signal resource A and SRS signal resource B, which can be understood as SRS signal resource A and SRS signal resource B being two different first resources. For example, the period associated with the first resource set is 5 time slots, indicating that the period of SRS signal resource A and SRS signal resource B included in the first resource set is 5 time slots. The indication information about SRS signal resource A includes the number of symbols being 2, the comb tooth size being 2, the time domain position of the last symbol being 3 time domain symbols away from the last time domain symbol in the time slot (the time domain position of the last symbol in the resource is the fourth to last time domain symbol in the time slot), and the number of resource repetitions being 2: According to the relationship between the number of symbols being 2, the comb tooth size being 2, and Table 1, the frequency domain offsets between two symbols in the SRS signal resource are 0 RE and 1 RE, respectively; according to the indication information about SRS signal resource A, the SRS signal resource is as follows: Figure 5 As shown in (a), according to the resource repetition number 2, the information indicates that the terminal device needs to send the SRS signal with the SRS signal resource in 2 adjacent uplink time slots, for example, send the SRS signal with the SRS signal resource in time slot 0 and time slot 1. The indication information about the SRS signal resource B includes the number of symbols of 2, the comb tooth size of 4, the time domain position of the last symbol is 3 time domain symbols away from the last time domain symbol in the time slot (the time domain position of the last symbol in the resource is the fourth to last time domain symbol in the time slot), and the resource repetition number 2: According to the number of symbols of 2, the comb tooth size of 4 and the relationship given in Table 1, the frequency domain offsets between two symbols in the SRS signal resource are 0 RE and 2 RE respectively; according to the indication information about the SRS signal resource B, the SRS signal resource is as follows: Figure 6 As shown in (a); according to the resource repetition number 2, the information indicates that the terminal device needs to send the SRS signal with the SRS signal resource in 2 adjacent uplink time slots, for example, send the SRS signal with the SRS signal resource in time slot 2 and time slot 3. In combination with the period of the first resource set being 5 time slots, the SRS signal can be sent with SRS resource A and SRS resource B in a period of every 5 time slots. For example, in the first period (the time period corresponding to time slot 0 to time slot 4, a total of 5 time slots), the terminal device sends the SRS signal with SRS resource A in time slot 0 and time slot 1, and sends the SRS signal with SRS resource B in time slot 2 and time slot 3. In the second period (the time period corresponding to time slot 5 to time slot 9, a total of 5 time slots), the terminal device sends the SRS signal with SRS resource A in time slot 5 and time slot 6, and sends the SRS signal with SRS resource B in time slot 7 and time slot 8, and so on, and sends periodically and continuously. The SRS signal sent by the terminal device can be used for perception, and the SRS signal sent by the terminal device can also be used for other functions, such as communication functions, which is not limited in the embodiments of the present application.

[0121] S402: The terminal device sends a first signal to the network device on the first resource. Correspondingly, the network device receives the first signal from the terminal device on the first resource.

[0122] The terminal device receives the first information from the network device, and can determine at least one of the following items according to the first information: the number of time domain symbols of the first resource, the comb tooth size, the time domain symbol interval, the position information of one of the time domain symbols included in the first resource, and the frequency domain offset information of REs included in different time domain symbols. Optionally, it can also be determined whether the first signal transmitted on the first resource is used for perception, and the number of resource repetitions associated with the first resource can also be determined. Optionally, the period of sending the first signal can also be determined.

[0123] After the terminal device determines the first resource, the period for sending the first signal, the number of repetitions and other information, the terminal device can send the first signal to the network device on the first resource according to the information. Optionally, before sending the first signal to the network device on the first resource, the terminal device can also receive downlink control information (DCI) from the network device for triggering the sending of the first signal, and send the first signal to the network device on the first resource in response to the DCI.

[0124] Furthermore, the network device receives the first signal from the terminal device on the first resource, and can perform perception, or perception and channel measurement, or perception and channel estimation, or perception and positioning, etc. according to the first signal. For example, the first signal will be reflected by the target in the environment and reach the network device. The network device can perceive the target in the environment by perceiving and processing the received first signal, for example, perceiving the position and speed of the target in the environment.

[0125] It can be understood that the above-mentioned term "determine" can also be referred to as "generate", the above-mentioned terms "send" and "receive" can also be referred to as "transmission", and the above-mentioned term "send" can also be referred to as "output". The embodiments of the present application do not limit the names of terms that can achieve the same function.

[0126] In this embodiment, compared to continuously arranging a large number of time domain symbol resources (for example, 12 consecutive time domain symbol resources) in the time domain, the overhead of sending the first signal can be reduced by indicating at least one of the first resource, the number of resource repetitions associated with the first resource, and whether the first resource is used for perception. Since the first resource includes non-continuous time domain symbols in the time domain, that is, a small number of time domain symbol resources are arranged at intervals in the time domain.
