Description

Communication method, device and computer-readable storage medium

[0001] This application claims priority to the Chinese patent application with application number 202311270988.9 filed with the State Intellectual Property Office of China on September 27, 2023, and priority to the Chinese patent application with the invention name “A communication method, device and computer-readable storage medium”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wireless communication technologies, and in particular to a communication method, device, and computer-readable storage medium. Background Art

[0003] Communication and perception integration combines wireless communication and perception into a single system, leveraging the propagation characteristics of wireless signals to achieve perception functions such as target location, detection, imaging, and identification, thereby acquiring information about the surrounding physical environment. For example, a terminal device can transmit a perception signal, and a network device can receive an echo signal, which is generated by the perception signal reflecting off an object in the environment. By receiving the echo signal, the network device can estimate parameters such as the position and velocity of the object in the environment, thereby obtaining relevant information about the object.

[0004] However, the resource overhead of the terminal device sending the SRS signal for sensing is too large, which is a waste. Therefore, how to reduce the overhead of the terminal device sending the SRS signal for sensing is an urgent problem to be solved.

[0005] Summary of the Invention

[0006] Embodiments of the present application provide a communication method, apparatus, and computer-readable storage medium that can reduce the overhead of sending signals.

[0007] 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 being used to indicate at least one of a first resource, the number of resource repetitions associated with the first resource, and whether the first resource is used for perception, 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, the resource units included in different time domain symbols of the first resource having different frequency domain offsets, and the first resource being used to transmit a first signal; and sending the first signal on the first resource.

[0008] In the solution provided in the present application, compared with continuously arranging a large number of time domain symbol resources in the time domain (for example, 12 consecutive time domain symbol resources), 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.

[0009] 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.

[0010] In one possible implementation, 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.

[0011] In one possible implementation, the 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.

[0012] In an 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 thus improve the perceptual 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.

[0013] In a possible implementation, the first set consists of 1, 2, 3, 4, 6, and 12.

[0014] In one possible implementation, the first information indicates that the first signal is used for sensing, and phase continuity is maintained when sending the first signal.

[0015] 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 is avoided, which makes it impossible to measure the speed.

[0016] In one 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 one time domain symbol in the time domain symbols included in the first resource, and the frequency domain offset information of the resource units included on different time domain symbols.

[0017] 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.

[0018] In a possible implementation, the first signal is a sounding reference signal or a positioning sounding reference signal.

[0019] In one possible implementation, the first signal is used for sensing, or for sensing and channel measurement, or for sensing and channel estimation, or for sensing and positioning.

[0020] 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 using 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, the 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, the resource units included in different time domain symbols of the first resource having different frequency domain offsets, and the first resource being used to transmit a first signal; and receiving a first signal on the first resource.

[0021] In the solution provided in the present application, compared with continuously arranging a large number of time domain symbol resources in the time domain (for example, 12 consecutive time domain symbol resources), 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.

[0059] The following is a description of the technical terms that may appear in the embodiments of this application. The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application. In the various embodiments of this application, unless otherwise specified or there is a logical conflict, the terms and / or descriptions between different embodiments are consistent and can be referenced to each other. The technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.

[0060] (1) Perception

[0061] Perception is the detection of parameters of targets in the physical environment, such as their position and velocity. A radar detection system can be understood as detecting targets by emitting electromagnetic waves and analyzing the reflected echo signals. Perception can also be referred to as detection.

[0062] (2) Perception Signal

[0063] 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. The specific sequence can be any 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 of the following sequences: a 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.

[0064] (3) Communication perception fusion signal

[0065] 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 communication reference signal sequence that needs to be transmitted between communication devices.

[0066] (4) Communication and perception integration

[0067] Communication and perception integration aims to integrate wireless communication and perception into a single system. This system leverages the various propagation characteristics of wireless signals to enable perception functions such as target location, detection, imaging, and identification. This allows the system to acquire information about the surrounding physical environment, unlock communication capabilities, and enhance the user experience. For example, a terminal device can transmit a perception signal, and a network device can receive an echo signal. This echo signal is generated by the perception signal reflecting off an object in the environment. By receiving the echo signal, the network device can estimate parameters such as the position and velocity of the object in the environment, thereby obtaining relevant information about the object.

[0068] (5) Sounding Reference Signal (SRS)

[0069] 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, massive multiple-input multiple-output (MIMO), etc. The sounding reference signal can also be used for beam management, including beam training and beam switching. In addition, for time division duplex (TDD) systems, the reciprocity of the uplink and downlink channels can be utilized to obtain 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.

[0070] It should be understood that the descriptions of the above technical terms are merely examples. For example, with the continuous development of technology, the scope of the above definitions may also change, and the embodiments of this application do not limit them.

[0071] The following is an example description of the network architecture applicable to the embodiments of the present application.

[0074] As shown in Figure 1, a network device and terminal devices 1 through 6 form a communication system. In this communication system, the network device sends downlink data to one or more of terminal devices 1 through 6. At the same time, terminal devices 1 through 6 can also send uplink data to the network device. Furthermore, aggregated transmission can be performed between terminal devices, such as terminal devices 4 through 6 shown in the figure. In this communication system, the network device can send downlink information to terminal devices 1, 2, and 5, and terminal device 5 can also send downlink information to terminal devices 4 and 6. Terminal devices 4 and 6 can also send uplink information to the network device through terminal device 5.

[0075] A terminal device is a device with wireless transceiver capabilities that can send signals to a base station or receive signals from a base station. A terminal device may also be referred to as user equipment (UE), a mobile station, a mobile terminal, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), the Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. A terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a wearable device, a vehicle, an airplane, a ship, a robot, a robotic arm, a smart home device, etc. The embodiments of this application do not limit the specific technology and specific device form adopted by the terminal device.

It can 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 can 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 can be a road side unit (RSU). All or part of the functions of the network device in the present application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as 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.

[0077] 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 set separately, 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 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 can 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 of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0078] The network device in this application may also be a device with a sensing function that can receive and process signals reflected by targets in the environment. Targets can be various tangible objects in the environment that can reflect electromagnetic waves, such as mountains, forests, or buildings. They can also include movable objects such as vehicles, drones, pedestrians, and terminal devices. Targets may also be referred to as sensed targets, detected targets, sensed objects, detected objects, or sensed devices, etc., and are not limited in the embodiments of this application.

[0079] 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 that includes the network device functions. The control subsystem that includes the network device functions 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 that includes the terminal device functions.

[0080] In this application, a network device sends a downlink signal or downlink information to a terminal device, and the downlink information is carried on a downlink channel; a terminal device sends an uplink signal or uplink information to a network device, and the uplink information is carried on an 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 serving cell of the terminal. When the terminal device communicates with the serving cell, it will also be interfered with by signals from neighboring cells.

[0081] In the embodiments of the present application, the time domain symbols may be orthogonal frequency division multiplexing (OFDM) symbols or discrete Fourier transform spread OFDM (DFT-s-OFDM) symbols. Unless otherwise specified, the symbols in the embodiments of the present application refer to time domain symbols.

[0082] Please refer to Figure 2, which is a schematic diagram of a perception scenario provided by an embodiment of the present application. In one possible implementation, a terminal device can send a perception signal, and a network device can receive an echo signal of the perception signal to achieve perception. For example, as shown in Figure 2 (a), the terminal device sends a perception signal, and the network device receives an echo signal generated by the perception signal being reflected by a target in the environment, thereby perceiving information such as the target's position and speed.

[0083] It should be noted that when the network device receives the echo signal of the perception signal sent by a terminal device, it can also simultaneously receive the communication signals or perception signals sent by other terminal devices in a frequency division multiplexing, space division multiplexing, etc. As shown in Figure 2 (b), the network device receives both the echo signal of the perception signal sent by terminal device A and the communication signals sent by other terminal devices (such as terminal device B) at the same time.

[0084] 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.

[0085] 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 one possible implementation, the detection reference signal can also be used for positioning. Please refer to Figure 3, which is a resource diagram of a detection reference signal for positioning provided by an embodiment of the present application. As shown in Figure 3, the resources of the detection reference signal for positioning may include 1, 2, 4, 8 or 12 consecutive time domain symbols in the time domain, and the period of the resource 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 (can also be understood as the initial phase), s m (t) represents the baseband signal of the mth time domain symbol, where 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 receiver 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 The Doppler shift caused by target motion is represented by A, while the amplitude attenuation of the echo signal relative to the transmitted signal (affected by the target's reflectivity and path loss). During sensing and processing, the distance to the target can be estimated by measuring and estimating the time delay of the echo signal relative to the transmitted signal, enabling ranging. The Doppler shift of the target can be estimated by measuring and estimating the time phase relationship between multiple echo signals, enabling speed measurement.

[0086] When using the detection reference signal for positioning and perception, the following problems may occur:

[0087] 1. The speed range of perception is determined by the signal transmission period. The maximum speed range is Where T represents the signal transmission period, λ t Indicates the wavelength of the transmitted signal. For perception, the signal loses a lot of energy after being reflected by the target, so it is necessary to send the signal multiple times for accumulation, such as 12 consecutive time domain symbols. When using a detection reference signal resource with 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 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 for normal perception scenarios does 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 in sending signals.

[0088] 2. The sounding reference signal used for positioning requires ranging but not speed measurement. That is, it only needs to estimate the relative delay between the transmitted and received signals, and does not need to estimate the Doppler shift (calculated by the phase difference between multiple received signals). The phase values ​​of the sounding reference signals sent on different time domain symbols may be randomly generated, that is, φ m Random generation 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.

[0089] 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.

[0090] The following describes a specific embodiment. It should be understood that the integration of perception and communication may change with the evolution of technical solutions, and the technical solutions provided in this application are not limited to the process described below. Furthermore, the description of the scenario in the embodiments of this application is only an example, and does not limit the solution of the embodiments of this application to be used only in the described scenario. It is also applicable to scenarios with similar problems.

[0091] A communication method provided by an embodiment of the present application is described below. Please refer to Figure 4, which is an interactive schematic diagram of a communication method provided by an embodiment of the present application. The terminal device in the embodiment of the present application may be a terminal device in the network architecture shown in Figure 1, and the function performed by the terminal device in this embodiment may 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 may be a network device in the network architecture shown in Figure 1, and the function performed by the network device in this embodiment may also be performed by a device in the network device (for example, a chip, or a chip system, or a circuit). As shown in Figure 4, the communication method may include the following steps.

[0092] S401: A network device sends first information to a terminal device, where the first information indicates 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. Accordingly, the terminal device receives the first information from the network device.

[0093] 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 can be used to transmit a first signal.

[0094] 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 signal, such as a physical uplink shared channel (PUSCH) signal, etc., which is not limited in the embodiment 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.

[0095] The first resource may include non-continuous time domain symbols in the time domain. The non-continuous time domain symbols may refer to that the absolute value of the difference between the numbers of any two adjacent time domain symbols included in the first resource in the time domain is greater than 1.

[0096] The first resource includes comb-shaped resource elements (REs) in the frequency domain, wherein the comb shape can be understood as the absolute value of the difference between the numbers of any two adjacent REs included in the REs on any time domain symbol included by 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 a comb tooth size C=2, that is, the first resource occupies the frequency domain resources in a 2-point comb shape on any time domain symbol included by it, that is, 1 RE is occupied in every 2 REs and the relative positions occupied by the occupied REs in every 2 REs are the same, or 1 RE is occupied every 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 by the first resource is 2. For another example, a 4-point comb pattern means a comb tooth size C=4, that is, the first resource occupies frequency domain resources in a 4-point comb pattern 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 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, and 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.

[0097] The frequency domain offsets of REs included in different time domain symbols of the first resource are different. In one 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 time domain symbol m is C×n+o m , where time domain symbol m refers to the mth time domain symbol in 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.

[0098] 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,…

[0099] 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 one 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. The position information of one 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, the offset information of REs included in different time domain symbols relative to the starting RE (for example, RE numbered 0).

[0100] In one 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 REs included in different time domain symbols. This correspondence can be presented in a tabular form, or the correspondence can be predefined in a protocol so that both the network device and the terminal device are known. Table 1 provides an exemplary explanation in tabular form.

[0101] Table 1 Correspondence between the number of time domain symbols of the first resource, comb tooth size, and frequency domain offset information of REs included in different time domain symbols

[0102] 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 the REs 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 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 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 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 are 0, 4, 2, and 6 respectively, that is, o1=0, o2=4, o3=2, and o4=6.

[0103] When 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 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 the RE 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 correspondence, thereby saving the signaling overhead of the first information.

[0104] 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.

[0105] 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. Please refer to Figure 5, which is a schematic diagram of a pattern of a first resource provided in an embodiment of the present application.

[0106] As shown in FIG5(a), a time slot includes 12 time domain symbols, and the first resource includes two non-contiguous 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, if the first time domain symbol is numbered 2, 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 size C = 2, and the offsets of the REs included in the first and second time domain symbols of the first resource relative to the RE numbered 0 are 0 and 1, respectively, that is, o1 = 0 and 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 the pattern of the first resource shown in (a) of Figure 5, the first information may indicate 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 fourth to last time domain symbol in the time slot, i.e., numbered 8), and the frequency domain offsets of the REs included in different time domain symbols are 0 and 1, respectively.

[0107] As shown in FIG5(b), a time slot includes 14 time domain symbols, and the first resource includes two non-contiguous 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 and second time domain symbols of the first resource is 7 time domain symbols. For example, if the first time domain symbol is numbered 2, the interval between the first and second time domain symbols is 7 symbols, that is, the second time domain symbol is numbered 2 + 7 = 9. The comb size C = 2, and the offsets of the REs included in the first and second time domain symbols of the first resource relative to the RE numbered 0 are 0 and 1, respectively, that is, o1 = 0 and o2 = 1. For example, the REs included in the first time domain symbol of the first resource are numbered 0, 2, 4, 6, 8, and 10, and the REs included in the second time domain symbol of the first resource are numbered 1, 3, 5, 7, 9, and 11. Exemplarily, for the pattern of the first resource shown in (b) of Figure 5, the first information may indicate 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 5th to last time domain symbol in the time slot, i.e., numbered 9), and the frequency domain offsets of the REs included in different time domain symbols are 0 and 1 respectively.

[0108] 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. Please refer to FIG6 , which is a schematic diagram of another pattern of the first resource provided in an embodiment of the present application.

[0109] As shown in FIG6(a), one time slot includes 12 time domain symbols, and the first resource includes two non-contiguous 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 size C = 4, and the offsets of the REs included in the first and second time domain symbols 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, and 8, and the resource elements included in the second time domain symbol of the first resource are numbered 2, 6, and 10. Exemplarily, for the pattern of the first resource shown in (a) of Figure 6, the first information may indicate 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 fourth 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.

[0110] As shown in FIG6(b), a time slot includes 14 time domain symbols, and the first resource includes two non-contiguous 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, if the first time domain symbol is numbered 2, 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 size C = 4, and the offsets of the REs included in the first and second time domain symbols of the first resource relative to the RE numbered 0 are 0 and 2, respectively, that is, o1 = 0 and o2 = 2. For example, the REs included in the first time domain symbol of the first resource are numbered 0, 4, and 8, and the REs included in the second time domain symbol of the first resource are numbered 2, 6, and 10. Exemplarily, for the pattern of the first resource shown in (b) of Figure 6, the first information may indicate 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 5th to last time domain symbol in the time slot, i.e., numbered 9), and the frequency domain offsets of the REs included in different time domain symbols are 0 and 2 respectively.

[0111] 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. Please refer to Figure 7, which is a schematic diagram of a pattern of another first resource provided in an embodiment of the present application. As shown in Figure 7, 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 and second time domain symbols is 3 symbols, i.e., the second time domain symbol is numbered 2+3=5, the interval between the second and third time domain symbols is 3 symbols, i.e., the third time domain symbol is numbered 5+3=8, and the interval between the third and fourth time domain symbols is 3 symbols, i.e., 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, second, third, and fourth time domain symbols of the first resource relative to the RE numbered 0 are 0, 1, 0, and 1, respectively, i.e., o1=0, o2=1, o3=0, and 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 the pattern of the first resource shown in FIG7 , 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 the REs included in different time domain symbols are 0, 1, 0, 1, respectively.

[0112] 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. Please refer to Figure 8, which is a schematic diagram of a pattern of another first resource provided in an embodiment of the present application. As shown in Figure 8, 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 and second time domain symbols is 3 symbols, i.e., the second time domain symbol is numbered 2+3=5, the interval between the second and third time domain symbols is 3 symbols, i.e., the third time domain symbol is numbered 5+3=8, and the interval between the third and fourth time domain symbols is 3 symbols, i.e., 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, second, third, and fourth time domain symbols of the first resource relative to the RE numbered 0 are 0, 2, 1, and 3, respectively, i.e., 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 the pattern of the first resource shown in FIG8 , 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 the REs included in different time domain symbols are 0, 2, 1, and 3, respectively.

[0113] 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. Please refer to Figure 9, which is a schematic diagram of a pattern of another first resource provided in an embodiment of the present application. As shown in Figure 9, 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 and second time domain symbols is 3 symbols, i.e., the second time domain symbol is numbered 2+3=5, the interval between the second and third time domain symbols is 3 symbols, i.e., the third time domain symbol is numbered 5+3=8, and the interval between the third and fourth time domain symbols is 3 symbols, i.e., 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, second, third, and fourth time domain symbols of the first resource relative to the RE numbered 0 are 0, 4, 2, and 6, respectively, i.e., 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 the pattern of the first resource shown in Figure 9, 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 the REs included in different time domain symbols are 0, 4, 2, and 6, respectively.

[0114] It can be seen from the above-mentioned embodiments that compared with 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.

[0115] 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 transmitted 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.

[0116] In one 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. This can be understood as the terminal device maintaining phase continuity in the time period where the first resource is located. This can also be understood as the absolute value of the difference between the phase values ​​of the signals sent by the terminal device at different time units in the time period where the first resource is located being less than a certain threshold, and this phase value can also be understood as the initial phase. This can also be understood as the difference between the phase values ​​of time slot p and time slot p-1 of the first device in the first time period being 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 being less than the second value, where p is an integer greater than or equal to 1. This can be understood as the first value and the second value being 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. This embodiment of the 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, the random phase of the signal sent by the radio frequency link can be avoided, thereby achieving speed measurement for perception.

[0117] 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 using 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 one 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, and 12; for another example, the first set consists of at least 2 of 1, 2, 3, 4, 6, and 12.

[0118] 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 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 thus improve the perceived coverage performance when the first signal is used for perception. 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 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.

[0119] Optionally, the first information may further 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 a period of X time slots (X is an integer greater than or equal to 1). For example, the first signal can be repeatedly sent once in each cycle with 10 time slots, 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 can be repeatedly sent three times in each cycle with the same spatial filter with 10 consecutive time slots, such as sending the first signal with the same spatial filter 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), sending the first signal with the same spatial filter in the 11th to 13th time slots (a total of 3 time slots) in the second cycle (the 11th to 20th time slots), and so on.

[0120] Optionally, the following provides an example of a network device indicating 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 uses an SRS signal as an example of the first signal.

[0121] Assume that the first information includes information indicating a first resource set, where the first resource set includes SRS signal resource A and SRS signal resource B. It can be understood that SRS signal resource A and SRS signal resource B are two different first resources. For example, the period associated with the first resource set is 5 time slots, and the period indicating that the SRS signal resource A and SRS signal resource B included in the first resource set have a period of 5 time slots. The indication information about the 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 time domain symbol from the last in the time slot), and the number of resource repetitions being 2: based on the number of symbols being 2, the comb tooth size being 2, and the relationship given in Table 1, the frequency domain offsets between the two symbols in the SRS signal resource are 0 RE and 1 RE, respectively; based on the indication information about the SRS signal resource A, the SRS signal resource is shown in (a) of FIG5 , and based on the number of resource repetitions being 2, the information indicates that the terminal device needs to send the SRS signal with the SRS signal resource in two adjacent uplink time slots, for example, sending 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 being 2, the comb tooth size being 4, 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 time domain symbol from the last in the time slot), and the number of resource repetitions being 2: based on the number of symbols being 2, the comb tooth size being 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; based on the indication information about the SRS signal resource B, the SRS signal resource is as shown in (a) of FIG6 ; based on the number of resource repetitions being 2, the information indicates that the terminal device needs to send the SRS signal with the SRS signal resource in two adjacent uplink time slots, for example, sending 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 continues to send periodically. 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 are not limited in the embodiments of the present application.

[0122] S402: The terminal device sends a first signal to the network device via a first resource. Correspondingly, the network device receives the first signal from the terminal device via the first resource.

[0123] The terminal device receives first information from the network device and can determine at least one of the following based on 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, the terminal device can also determine whether the first signal transmitted on the first resource is used for sensing, the number of resource repetitions associated with the first resource, and the like. Optionally, the terminal device can also determine a period for sending the first signal.

[0124] After the terminal device determines the first resource, the period for sending the first signal, the number of repetitions, and other information, it can send the first signal to the network device on the first resource based on this 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.

[0125] Furthermore, the network device receives a first signal from the terminal device on the first resource and can perform perception, perception and channel measurement, perception and channel estimation, perception and positioning, etc. based on the first signal. For example, the first signal may be reflected by an object in the environment and reach the network device. The network device senses and processes the received first signal to achieve perception of the object in the environment, such as the position and speed of the object in the environment.

[0126] It can be understood that the above-mentioned term "determine" can also be called "generate", the above-mentioned terms "send" and "receive" can also be called "transmit", and the above-mentioned term "send" can also be called "output". The embodiments of this application do not limit the names of terms that can achieve the same function.

[0127] In this embodiment, compared to continuously arranging a large number of time domain symbol resources in the time domain (for example, 12 consecutive time domain symbol resources), 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.

For ease of explanation, Figure 13 only shows the main components of the terminal device. As shown in Figure 13, the terminal device 1300 includes a processor, a memory, a control circuit, an antenna, and input and output devices. The processor is mainly used to process communication protocols and communication data, as well as to control the entire terminal, execute software programs, and process data of software programs. The memory is mainly used to store software programs and data. The radio frequency circuit is mainly used for converting baseband signals and radio frequency signals and processing radio frequency signals. The antenna is mainly used to transmit and receive radio frequency signals in the form of electromagnetic waves. Input and output devices, such as touch screens, display screens, keyboards, etc., are mainly used to receive data input by users and output data to users.

[0187] When the terminal is powered on, the processor reads the software program from the storage unit, parses and executes the instructions of the software program, and processes the data of the software program. When data needs to be sent wirelessly, the processor performs baseband processing on the data to be sent and outputs the baseband signal to the RF circuit. The RF circuit processes the baseband signal to obtain an RF signal and transmits the RF signal to the outside in the form of electromagnetic waves via the antenna. When data is sent to the terminal, the RF circuit receives the RF signal via the antenna, which is further converted into a baseband signal and output to the processor. The processor converts the baseband signal into data and processes the data.

[0188] For ease of explanation, FIG13 shows only one memory and processor. In an actual terminal, there may be multiple processors and memories. The memory may also be referred to as a storage medium or storage device, etc., which is not limited in the present embodiment.

[0189] As an optional implementation, the processor may include a baseband processor and a central processing unit (CPU). The baseband processor is primarily responsible for processing communication protocols and communication data, while the CPU is primarily responsible for controlling the entire terminal, executing software programs, and processing data from software programs. The processor in Figure 13 integrates the functions of both the baseband processor and the CPU. Those skilled in the art will appreciate that the baseband processor and the CPU may also be independent processors interconnected via a bus or other technology. Those skilled in the art will appreciate that a terminal may include multiple baseband processors to accommodate different network standards, multiple CPUs to enhance its processing capabilities, and that the various components of the terminal may be connected via various buses. The baseband processor may also be referred to as a baseband processing circuit or a baseband processing chip. The CPU may also be referred to as a central processing circuit or a central processing chip. The functionality for processing communication protocols and communication data may be built into the processor or stored as a software program in a storage unit, with the processor executing the software program to implement the baseband processing functionality.
