Description

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on April 30, 2021, with application number 202110482926.9 and invention name “Signal Transmission Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a signal transmission method and a communication device. Background Art

[0003] Radar communication integration technology can simultaneously realize radar detection and data transmission functions. That is, network equipment can send radar detection signals to realize radar detection functions, and send synchronization signal block (SSB) signals to synchronize terminal devices and network equipment to realize data transmission functions.

[0004] However, if the transmission resources of the radar detection signal and the SSB signal overlap in the time domain, that is, the network equipment sends the radar detection signal and the SSB signal at the same time, interference is likely to occur between the different signals, and the system communication efficiency is low. Summary of the Invention

[0005] An embodiment of the present application provides a signal transmission method and a communication device, which can avoid interference between a first signal (such as a radar detection signal) and a synchronization signal block SSB signal, thereby improving system communication efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions:

[0007] In a first aspect, an embodiment of the present application provides a signal transmission method, wherein the execution subject of the method can be a network device or a chip used in the network device. The following description takes the execution subject being a network device as an example. The method includes: the network device determines a first resource, wherein the first resource and the second resource do not overlap in the time domain, the second resource is used to send a synchronization signal block (SSB) signal, and the first resource and the second resource have a corresponding relationship. Then, the network device transmits at least one first signal on the first resource, wherein the first signal is used to detect the attributes of the target. The corresponding relationship between the first resource and the second resource means that the first resource and the second resource have a corresponding relationship in resource position.

[0008] In other words, the first resource determined by the network device is a resource that does not overlap with the second resource in the time domain, and there is a corresponding relationship between the two resource locations. In this way, the first signal and the SSB signal are sent at different times, so that the first signal and the SSB signal do not collide with each other and do not interfere with each other, thereby improving system communication efficiency.

[0009] In one possible design, within a target duration, the first resource does not include resources in the third resource that overlap with a candidate position of the SSB signal, wherein the target duration is comprised of at least one time slot in which the second resource is located, and the third resource is determined based on a transmission period of the first signal.

[0010] That is to say, the first resource is the resource in the third resource excluding the resource overlapping with the candidate position of the SSB signal. Therefore, the network device does not transmit the first signal and the SSB signal at the same time, thereby avoiding collision between the first signal and the SSB signal to improve system communication efficiency.

[0011] In one possible design, when part of the third resources overlap with the candidate position of the SSB signal, the first resources include at least: resources that advance or delay the resources in the third resources that overlap with the candidate position of the SSB signal by at least one time domain symbol.

[0012] That is to say, when some resources in the third resource overlap with the candidate position of the SSB signal, the resources overlapping with the candidate position of the SSB signal are moved (such as advanced or delayed) to avoid the network device transmitting the first signal and the SSB signal at the same time.

[0013] In one possible design, within the target duration, the first resource is composed of resources in the third resource that do not overlap with the candidate position of the SSB signal.

[0014] That is to say, the resources constituting the first resource do not overlap with the candidate positions of the SSB signal, thereby avoiding the network device transmitting the first signal and the SSB signal at the same time.

[0015] In one possible design, the first resource is determined based on the second resource. That is, the first resource is a resource that is adjusted based on the second resource so that the first resource and the second resource do not overlap in the time domain.

[0016] In one possible design, the first interval is different from the second interval. The first interval is an interval between two adjacent first signals in at least one first signal within a target duration. The second interval is an interval between two adjacent first signals in at least one first signal outside the target duration. The target duration is composed of at least one time slot in which the second resource is located.

[0017] That is, the time interval between two adjacent first signals within the target duration is different from the time interval between two adjacent first signals outside the target duration.

[0018] In one possible design, there are multiple first intervals, and the duration of each of the multiple first intervals is the same. The multiple first intervals means that the network device transmits multiple first signals within the target duration, with a first interval between each two adjacent first signals. Thus, the number of first intervals is multiple. In other words, the first signals are transmitted at equal intervals within the target duration.

[0019] In one possible design, within the target duration, the first resource includes a time domain resource unit whose index value is a first preset value.

[0020] In one possible design, the time domain resource unit is a time domain symbol, and the first preset value includes one of the following: 0, 1, 12, or 13.

[0021] That is to say, when the subcarrier spacing for transmitting SSB signals is 120kHz, with a single time slot as the granularity, the time domain symbol indexes that are never occupied by the second resource are as follows: 0, 1, 12, and 13. Therefore, the first resource occupies one of the symbols 0, 1, 12, or 13 in a time slot within the target time length, and does not overlap with the second resource in the time domain, thereby avoiding collision between the first signal and the SSB signal.

[0022] In one possible design, there are multiple first intervals, and at least two of the multiple first intervals have different time lengths. In other words, the first signal may not be transmitted at equal intervals within the target duration.

[0023] In one possible design, within the target duration, the first resource includes a time domain resource unit whose index value is a second preset value.

[0024] In one possible design, the time-domain resource unit is a time-domain symbol, and the time-domain symbol is distributed in two consecutive time slots. The second preset value includes at least three of the following: 0, 1, 2, 3, 12, 13, 14, 15, 24, 25, 26, or 27. A difference between any two of the second preset values ​​is greater than or equal to a third preset value.

[0025] In other words, at least three first resources exist in every two consecutive time slots. In other words, transmitting at least three first signals every two time slots increases the time-domain density of the first signals, which helps improve radar detection accuracy. Furthermore, the difference between any two of the second preset values ​​is greater than or equal to the third preset value, making the first resources non-continuous in the time domain. This, to a certain extent, ensures a uniform distribution of the first signals.

[0026] In one possible design, the time domain resource unit is a time domain symbol, and the time domain symbol is distributed in two consecutive time slots, and the second preset value includes: 3, 13, 24, or the second preset value includes: 13, 20, 27.

[0027] In one possible design, the second resource is determined based on the first resource. That is, the second resource is a resource that is adjusted based on the first resource so that the first resource and the second resource do not overlap in the time domain.

[0028] In one possible design, the first interval is the same as the second interval. The first interval is the interval between two adjacent first signals in at least one first signal within the target duration. The second interval is the interval between two adjacent first signals in at least one first signal outside the target duration. The target duration is composed of at least one time slot where the candidate position of the SSB signal is located.

[0029] That is to say, no matter within the target duration or outside the target duration, the first signal maintains the same transmission period.

[0030] In one possible design, within the target duration, the second resource includes a time domain resource unit whose index value is a fourth preset value, and the fourth preset value satisfies the following formula:

[0031]

[0032] Wherein, M represents the fourth preset value, N is an integer, and 0≤N≤27, and k is a positive integer.

[0033] That is, when the transmission period of the first signal is 7 time domain symbols, the time domain symbol index of the first resource satisfies: 7*k-1. In the process of N traversing 28 integers (i.e., from 0 to 27), the time domain symbol index carrying the SSB signal is not equal to the time domain symbol index of the first resource, thereby avoiding overlap between the first resource and the second resource in the time domain.

[0034] In one possible design, within the target duration, the second resource includes a time domain resource unit whose index value is a fourth preset value, and the fourth preset value satisfies the following formula:

[0035]

[0036] Wherein, M represents the fourth preset value, and the value of N includes at least two of the following: 0, 1, 2, 7, 8, 9, 14, 15, 16, 21, 22, or 23.

[0037] In a possible design, the value of N includes: 2, 8, 16, or 22.

[0038] In one possible design, the signal transmission method of an embodiment of the present application further includes: the network device sends indication information to the terminal device, wherein the indication information indicates the index value.

[0039] That is to say, when the resource position of the first resource remains unchanged and the second resource is determined based on the first resource, the network device first indicates the index value of the second resource to the terminal device so that the terminal device receives the SSB signal at the resource position indicated by the indication information.

[0040] In a second aspect, embodiments of the present application provide a signal transmission method. This method can be performed by a terminal device or a chip implemented in the terminal device. The following description uses the terminal device as an example. The method includes: the terminal device receiving indication information. The indication information indicates location information of a second resource. The terminal device then receives a synchronization signal block (SSB) signal on the second resource.

[0041] That is to say, when the resource location of the first resource remains unchanged and the second resource is determined based on the first resource, the network device first indicates the location information of the second resource to the terminal device, and the terminal device receives the SSB signal at the resource location indicated by the indication information.

[0042] In one possible design, the location information of the second resource includes a fourth preset value. The fourth preset value includes an index value of a time domain resource unit of the second resource, and the fourth preset value satisfies the following formula:

[0043]

[0044] Wherein, M represents the fourth preset value, N is an integer, and 0≤N≤27, and k is a positive integer.

[0045] In one possible design, the location information of the second resource includes a fourth preset value. The fourth preset value includes an index value of a time domain resource unit of the second resource, and the fourth preset value satisfies the following formula:

[0046]

[0047] Wherein, M represents the fourth preset value, and the value of N includes at least two of the following: 0, 1, 2, 7, 8, 9, 14, 15, 16, 21, 22, or 23.

[0048] In a possible design, the value of N includes: 2, 8, 16, or 22.

[0049] In a third aspect, embodiments of the present application provide a signal transmission method. The method may be performed by a network device or a chip used in the network device. The following description uses the network device as an example. The method includes: the network device determines a first resource. The first resource and a second resource overlap in the time domain and do not overlap in the frequency domain, and the second resource is used to transmit a communication signal. The first resource and the second resource have a corresponding relationship. The network device then transmits at least one first signal on the first resource. The first signal is used to detect attributes of a target.

[0050] In other words, the first resource determined by the network device overlaps with the second resource in the time domain but does not overlap with the second resource in the frequency domain, with a corresponding relationship between the two resource locations. This way, the first signal and the communication signal are transmitted via different frequency domain resources, preventing collision and interference between the first signal and the communication signal, thereby improving system communication efficiency.

[0051] In one possible design, the first resource includes X frequency domain resource units with the smallest frequencies in the system bandwidth, where X is a positive integer. Alternatively, the first resource includes Y frequency domain resource units with the largest frequencies in the system bandwidth, where Y is a positive integer.

[0053] The first item states that the sum of the first bandwidth and the bandwidth of the communication signal is less than or equal to the system bandwidth. The first bandwidth is the bandwidth when the first signal and the communication signal overlap in the time domain. That is, when the bandwidth configured for the first signal is the system bandwidth, the network device indicates to the terminal device the first bandwidth when the first signal and the communication signal overlap, so that the terminal device receives the first signal based on the first bandwidth indicated by the indication information.

[0054] The second item, the second bandwidth, is equal to the system bandwidth. The second bandwidth is the bandwidth when the first signal and the communication signal do not overlap in the time domain. That is, when the bandwidth configured for the first signal is the system bandwidth, the network device indicates to the terminal device the second bandwidth when the first signal and the communication signal do not overlap, so that the terminal device receives the first signal based on the second bandwidth indicated by the indication information.

[0157] The terms "first," "second," and so on in the description and drawings of this application are used to distinguish different objects or to distinguish different processes on the same object, rather than to describe a specific order of objects. Furthermore, the terms "including," "having," and any variations thereof, mentioned in the description of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device comprising a series of steps or units is not limited to the listed steps or units but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or device. In the embodiments of this application, "multiple" includes two or more. In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate an example, illustration, or explanation. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner. In the embodiments of this application, "transmitting" may include "sending" or "receiving," or may include both sending and receiving, depending on the specific situation.

[0158] First, let’s introduce the technical terms involved in this application:

[0159] 1. Synchronization signal block (SSB) signal

[0160] In new radio (NR), network devices periodically send SSB signals. An SSB signal includes a synchronization signal (SS) and a physical broadcast channel (PBCH). The SS includes a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). Terminal devices use PSS and SSS to identify cells and synchronize with them. Terminal devices obtain the most basic system information, such as system frame number, intra-frame timing information, etc., through PBCH. The successful reception of the SSB signal by a terminal device is a prerequisite for it to access the cell.

[0161] like Figure 1 As shown, in the time domain, an SSB signal occupies 4 time domain symbols, such as Figure 1The time domain symbols are numbered from 0 to 3. In the frequency domain, an SSB signal occupies 20 resource blocks (RBs), that is, 240 subcarriers. Within these 20 RBs, the subcarriers are numbered from 0 to 239. The PSS is located on the middle 127 subcarriers of the time domain symbol 0, and the SSS is located on the middle 127 subcarriers of the time domain symbol 2. In order to protect the PSS and SSS, different protection subcarriers are set to 0, that is, the protection subcarriers are not used to carry signals. 8 subcarriers and 9 subcarriers are reserved on both sides of the SSS as guard band subcarriers, such as Figure 1 The blank areas on both sides of the SSS in the PBCH are the guard subcarriers. The PBCH occupies all subcarriers in time domain symbols 1 and 3, as well as a portion of the remaining subcarriers in time domain symbol 2, excluding the subcarriers occupied by the SSS (i.e., the remaining subcarriers excluding the guard subcarriers).

[0162] An SSB signal is associated with an index to identify the SSB signal. In a half-frame, when the index of an SSB signal is 0, the SSB signal identified by the index is the first SSB signal in the half-frame. When the index of an SSB signal is 1, the SSB signal identified by the index is the second SSB signal in the half-frame, and so on. For example, in Figure 2a In the , the SSB signal identified by index 0 is the first SSB signal in the half frame, and the index of the time domain symbol it occupies is 4 to 7. The SSB signal identified by index 1 is the second SSB signal in the half frame, and the index of the time domain symbol it occupies is 8 to 11. The SSB signal identified by index 2 is the third SSB signal in the half frame, and the index of the time domain symbol it occupies is 16 to 19. The SSB signal identified by index 3 is the fourth SSB signal in the half frame, and the index of the time domain symbol it occupies is 20 to 23. In Figure 2b In the example, the SSB signal identified by index 0 is the first SSB signal in the half frame, and the index of the time domain symbol it occupies is 4 to 7. The SSB signal identified by index 1 is the second SSB signal in the half frame, and the index of the time domain symbol it occupies is 16 to 19. Two SSB signals that are consecutive in index can be consecutive in the time domain, such as Figure 2a The SSB signal identified by index 0 and the SSB signal identified by index 1. Two SSB signals that are consecutive in index may also be discontinuous in the time domain, such as Figure 2b The SSB signal identified by index 0 and the SSB signal identified by index 1.

[0163] It should be noted that if the subcarrier spacing (SCS) of the SSB signal is different, the candidate positions of the SSB signal will also be different. Below, based on different subcarrier spacings, the candidate positions of the SSB signal are introduced in five cases:

[0164] Case A: When the SCS is 15kHz, the time domain symbol index of the SSB signal satisfies:

[0165] {2,8}+14*n formula (1)

[0166] In the absence of shared spectrum channel access, if the carrier frequency is less than or equal to 3 GHz, then n = 0, 1; if the frequency range is greater than 3 GHz, then n = 0, 1, 2, 3. In the presence of shared spectrum channel access, n = 0, 1, 2, 3, 4.

[0167] For example, in the case of shared spectrum channel access, there are a maximum of 10 candidate positions for the SSB signal. When n = 0, there are two candidate positions for the SSB signal. The first time domain symbol index of the first candidate position is 2, and the first time domain symbol index of the second candidate position is 8.

[0168] Case B, when the SCS is 30kHz, the time domain symbol index of the SSB signal satisfies:

[0169] {4, 8, 16, 20}+28*n formula (2)

[0170] If the carrier frequency is less than or equal to 3 GHz, then n=0; if the frequency range is greater than 3 GHz, then n=0, 1.

[0171] Case C, when the SCS is 30kHz, the time domain symbol index of the SSB signal satisfies:

[0172] {2,8}+14*n formula (3)

[0173] In the absence of shared spectrum channel access, for paired spectrum, if the carrier frequency is less than or equal to 3 GHz, n = 0, 1; if the frequency range is greater than 3 GHz, n = 0, 1, 2, 3. For unpaired spectrum, if the carrier frequency is less than 1.88 GHz, n = 0, 1; if the frequency range is greater than or equal to 1.88 GHz, n = 0, 1, 2, 3. With shared spectrum channel access, n = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

[0174] Case D, when the SCS is 120kHz, the time domain symbol index of the SSB signal satisfies:

[0175] {4, 8, 16, 20}+28*n formula (4)

[0176] If the carrier frequency band belongs to frequency range 2 (FR2), then n=0, 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 15, 16, 17, 18.

[0177] Case E: When the SCS is 240kHz, the time domain symbol index of the SSB signal satisfies:

[0178] {8, 12, 16, 20, 32, 36, 40, 44}+56*n formula (5)

[0179] If the carrier frequency band belongs to FR2, then n=0, 1, 2, 3, 5, 6, 7, 8.

[0180] It should be noted that during synchronization between the terminal device and the network device, the terminal device receives the SSB signal from the network device at the candidate position of the SSB signal in accordance with the protocol, and the network device does not need to indicate the candidate position of the SSB signal to the terminal device. The above formulas (1) to (5) all indicate the index of the first time domain symbol of the candidate position of the SSB signal.

[0181] 2. Frequency range

[0182] In the 3GPP protocol, the overall spectrum resources of the 5th generation mobile communication technology (5G) network can be divided into the following two frequency ranges, as shown in Table 1:

[0183] Table 1

[0184] Frequency range name Frequency range FR1 410MHz–7125MHz FR2 24250MHz–52600MHz

[0185] It should be understood that the above-mentioned names of FR1 and FR2 shall not constitute any limitation to the present application, and the present application does not exclude the possibility of defining other names in future agreements to express the same or similar meanings.

[0186] FR1: Sub-6GHz band, in other words, the low-frequency band, the primary frequency band for 5G networks. In FR1, frequencies below 3GHz are referred to as Sub-3G, and the remaining bands are referred to as C-band. It should be understood that the frequency range corresponding to FR1 can correspond to 410MHz–7125MHz as shown in Table 1, but is not limited to this. This application does not exclude the possibility of defining other ranges in future agreements to represent the same or similar meanings.

[0187] FR2: millimeter waves above 6GHz, in other words, high-frequency bands, are extended bands for 5G networks and have abundant spectrum resources. It should be understood that the frequency range corresponding to FR2 can correspond to 24250MHz–52600MHz as shown in Table 1, but is not limited to this. This application does not exclude the possibility of defining other ranges in future agreements to represent the same or similar meanings.

[0188] 3. Radar detection

[0189] A radar device transmits a radar detection signal, which is diffusely reflected by a target object, forming an echo signal. The radar device then receives the echo signal reflected by the target object and uses the radar detection signal and the echo signal to detect the target object, such as determining the target's distance, direction, altitude, speed, attitude, shape, and other characteristic parameters. A radar device may also be referred to as a radar, detector, or radar detection device.

[0190] Radar detection, also known as radar perception, is widely used in scenarios such as traffic detection and weather monitoring. However, using radar alone for wide-range detection is costly. Therefore, integrating the abundant spectrum resources of wireless communications with radar detection can support large-scale requirements such as continuous networking.

[0191] 4. Radar communication integration

[0192] Radar communication integration refers to the simultaneous implementation of radar detection and data transmission through shared hardware. After radar detection functionality is integrated into network devices, the network devices transmit radar detection signals to implement the radar detection function and SSB signals to synchronize the terminal devices with the network devices for data transmission.

[0193] However, when the transmission resources of the radar detection signal overlap with the transmission resources of the SSB signal, that is, the network equipment sends the radar detection signal and the SSB signal at the same time, interference is easily generated between the different signals, affecting the normal transmission of the radar detection signal and the SSB signal, and the system communication efficiency is low.

[0194] In view of this, an embodiment of the present application provides a signal transmission method, which is applicable to various communication systems. The signal transmission method provided in the embodiment of the present application can be applied to a long term evolution (LTE) system, a 5G network, or other similar networks, or other future networks. Figure 3 3 is a schematic diagram of the architecture of a communication system applicable to the signal transmission method of an embodiment of the present application, wherein the communication system includes a network device 301 and terminal devices 302-307. Figure 3 Only one network device and six terminal devices are shown. Figure 3 This is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the signal transmission method in the embodiment of the present application.

[0195] Terminal devices may also be referred to as user equipment (UE), terminal, access terminal, user unit, user station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or user device. Terminal devices can be either wireless or wired. A wireless terminal refers to a device with wireless transceiver capabilities that can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water (such as ships); or in the air (such as aircraft, balloons, and satellites). The terminal device may be a drone, an Internet of Things (IoT) device (e.g., a sensor, an electricity meter, a water meter, etc.), a vehicle-to-everything (V2X) device, a station (ST) in a wireless local area network (WLAN), a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device (also referred to as a wearable smart device). The terminal device may also be a terminal in a next-generation communication system, such as a terminal in a 5G communication system or a terminal in a future-evolved public land mobile network (PLMN), etc., and the embodiments of the present application do not limit this. For example, in Figure 3In the figure, the terminal device can be a high-speed rail communication device 302, a smart air conditioner 303, a smart gas station 304, a mobile phone 305, a smart tea cup 306, a printer 307, etc., and this embodiment of the application does not limit this.

[0196] A network device is a device in a wireless communication network, such as a radio access network (RAN) node that connects a terminal device to the wireless communication network. Currently, some examples of RAN nodes include: gNB, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), base band unit (BBU), wireless fidelity (Wi-Fi) access point (AP), or network-side equipment in 5G communication networks or post-5G communication networks. A network device can be a single physical entity or a combination of multiple physical entities, which can be deployed in the same location or in different locations, and are used to jointly implement the functions of the network entity.

[0197] The communication system and service scenarios described in the embodiments of this application are intended to more clearly illustrate the technical solutions of the embodiments of this application and do not constitute a limitation on the technical solutions provided by the embodiments of this application. Those skilled in the art will appreciate that, with the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

[0198] The signal transmission method provided in an embodiment of the present application is described in detail below. The technical concept of the signal transmission method in an embodiment of the present application is as follows: a network device determines a first resource, wherein the first resource and the second resource do not overlap in the time domain, the second resource is used to send a synchronization signal block (SSB) signal, and the first resource and the second resource have a corresponding relationship. Then, the network device transmits at least one first signal on the first resource, wherein the first signal is used to detect the attributes of the target. In other words, the first resource determined by the network device is a resource that does not overlap with the second resource in the time domain, and there is a corresponding relationship between the two in terms of resource location. In this way, the transmission time of the first signal and the SSB signal are different, so that the first signal and the SSB signal do not collide and interfere with each other, thereby improving system communication efficiency. Exemplarily, the first signal can be a radar detection signal or an echo signal of a radar detection signal. There is a corresponding relationship between the first resource and the second resource. For detailed description, please refer to the following introduction and will not be repeated here.

[0199] As an implementation method, the first resource is determined based on the second resource. That is, when the resource position of the second resource remains unchanged, the resource position of the first signal is adjusted to obtain the first resource, so that the first resource and the second resource do not overlap in the time domain. Among them, the second resource is a resource for sending the SSB signal determined from the candidate position of the SSB signal. In the embodiment of the present application, the candidate position of the SSB signal is the candidate position specified in the 3GPP protocol technical specification (TS) 38.213. For details, please refer to the introduction of the above five cases.

[0200] As another embodiment, the second resource is determined based on the first resource. That is, while the transmission period of the first signal remains unchanged, the candidate position of the SSB signal is adjusted to obtain the second resource, thereby achieving non-overlap between the first resource and the second resource in the time domain.

[0201] The embodiments of the present application are described below with reference to specific examples. The message names between network elements or the names of parameters in the messages in the following embodiments are merely examples and may be other names in specific implementations. In the embodiments of the present application, when a single time slot is used as the granularity, when the prefix of the time domain symbol is a normal cyclic prefix (NCP), the index value range of the time domain symbol is [0, 13]. When two consecutive time slots are used as the granularity, the index value range of the time domain symbol is [0, 27]. The first resource is used to transmit at least one first signal. The second resource is used to transmit at least one SSB signal. The third resource is a resource determined based on the transmission period of the first signal, that is, the resource where the first signal is located without considering interference with the SSB. The correspondence between the first resource and the second resource may mean that, within a preset number of time domain resource units, the first resource and the second resource have a corresponding relationship in resource position, such as a corresponding relationship in resource position between one first resource and each second resource among multiple second resources, or a corresponding relationship in resource position between each first resource among multiple first resources and each second resource among multiple second resources. For example, taking a single time slot as the granularity, in the same time slot, the number of first resources is one, occupying the time domain symbol with index 13. The number of second resources is two, and the occupied time domain symbol indices include: 4, 5, 6, 7, 8, 9, 10, and 11. In the time slot, one first resource and two second resources have corresponding relationships in the time domain symbols, such as the first resource and the first second resource are separated by 9 time domain symbols in the time domain, and the first resource and the second second resource are separated by 5 time domain symbols in the time domain. For another example, taking a single time slot as the granularity, in the same time slot, the number of first resources is two, and the occupied time domain symbol indices include 3 and 13. The number of second resources is two, and the occupied time domain symbol indices include: 4 to 11. In this time slot, each first resource and each second resource have a corresponding relationship in the time domain symbols. For example, the first first resource and the first second resource are continuous in the time domain, the first first resource and the second second resource are separated by 5 time domain symbols in the time domain, the second first resource and the first second resource are separated by 9 time domain symbols in the time domain, and the second first resource and the second second resource are separated by 4 time domain symbols in the time domain. For another example, taking two consecutive time slots as the granularity, in two consecutive time slots, the number of first resources is three, and the occupied time domain symbol indices include 3, 13, and 24. The number of second resources is four, and the occupied time domain symbol indices include: 4 to 11, and 16 to 23.In this time slot, each first resource and each second resource have a corresponding relationship in the time domain symbol. For example, the position relationship between the first first resource and the four second resources in the time domain is: continuous in the time domain, 5 time domain symbols apart, 13 time domain symbols apart, and 20 time domain symbols apart. The position relationship between the second first resource and the four second resources in the time domain is: 9 time domain symbols apart, 5 time domain symbols apart, 3 time domain symbols apart, and 7 time domain symbols apart. The position relationship between the third first resource and the four second resources in the time domain is: 20 time domain symbols apart, 16 time domain symbols apart, 8 time domain symbols apart, and continuous in the time domain. In an embodiment of the present application, the interval between two resources refers to the difference determined based on the indexes of the two resources. For example, in the same time slot, resource 1 occupies a time domain symbol index of 1, and resource 2 occupies a time domain symbol index of 6, then the interval between resource 1 and resource 2 is 5 time domain symbols. It should be understood that the interval between the two resources can also be equivalently replaced by the number of time domain resource units located between the two resources, but the difference in value is 1. Still taking the above-mentioned resource 1 and resource 2 as an example, the number of time domain symbols located between resource 1 and resource 2 is 4. In addition, the above-mentioned at least one first signal can also be described as a first signal as a whole. There is at least one first resource, and each first resource in the at least one first resource carries a signal, and the signal carried on each first resource is described as a sub-signal. In other words, the first signal includes at least one sub-signal. For the convenience of description, in the embodiment of the present application, the network device is network device 301 and the terminal device is terminal device 305 as an example for introduction. This is a unified explanation here and will not be repeated below.

[0202] The embodiment of the present application provides a signal transmission method 400, which is applied in the signal transmission process of radar communication integration. Figure 4 , the method comprises the following steps:

[0203] S401: The network device 301 determines a first resource.

[0204] The first resource and the second resource do not overlap in the time domain. The number of first resources is one or more, and any two adjacent first resources among the multiple first resources may be continuous or discontinuous in the time domain. Each first resource may be a time domain symbol. Specifically, the network device 301 may determine one or more first resources. It is understandable that the first resource and the second resource do not overlap in the time domain. When the number of first resources and the number of second resources are both multiple, any first resource among the multiple first resources and any second resource among the multiple second resources do not overlap in the time domain.

[0205] Each second resource may be four consecutive time domain symbols in the time domain, see Figure 1The number of the second resources can be multiple, and among the multiple second resources, any two adjacent second resources can be continuous in the time domain, such as Figure 2a The time domain resources occupied by the SSB with index 0 and the time domain resources occupied by the SSB with index 1 are continuous, and the time domain resources occupied by the SSB with index 2 and the time domain resources occupied by the SSB with index 3 are continuous. Any two second resources may also be discontinuous, such as Figure 2a In the example, the time domain resources occupied by the SSB with index 1 and the time domain resources occupied by the SSB with index 2 are discontinuous. Figure 2b In the example, the time domain resources occupied by the SSB with index 0 and the time domain resources occupied by the SSB with index 1 are discontinuous.

[0206] The specific implementation methods of S401 include the following two methods:

[0207] As a first implementation method, the first resource is determined based on the second resource. That is, when the resource position of the second resource remains unchanged, the resource position of the first signal is adjusted to obtain the first resource, so that the first resource and the second resource do not overlap in the time domain. Among them, the second resource is a resource for sending the SSB signal determined from the candidate position of the SSB signal. Exemplarily, when the third resource overlaps with the candidate position of the SSB signal, the first resource does not include the resource in the third resource that overlaps with the candidate position of the SSB signal. Below, three examples are introduced:

[0208] As an example of the first implementation method, when the resource location density of the second resource is high, the first signal is still transmitted at equal intervals within the target duration. The target duration is composed of at least one time slot where the second resource is located. Taking the second resource belonging to the resource location specified in 3GPP TS 38.213 as an example, the target duration is one half frame, which is 5ms. The resource location density of the second resource is high, which can mean that the number of SSB signals is less than or equal to 64, that is, it can be understood that the number of SSB signals included in an SSB burst is less than or equal to 64. For example, in the protocol 3GPP TS 38.213, when the subcarrier spacing of the subcarrier transmitting the SSB signal is 120kHz, the candidate positions of the SSB signal can support a maximum of 64, that is, in formula (4), the number of values ​​of n reaches the maximum, which is 16. When the candidate positions of the SSB signal are full, the number of SSB signals is 64, that is, 64 SSB signals are sent within 5ms.

[0209] That is, within the target duration, the intervals between any two adjacent first signals are the same. In other words, within the target duration, when the interval between two adjacent first signals in the at least one first signal is recorded as the first interval, there are multiple first intervals, and the duration of each of the multiple first intervals is the same. The multiple first intervals mean that the network device 301 transmits multiple first signals within the target duration, with one first interval between each two adjacent first signals. Thus, the number of first intervals is multiple.

[0210] Exemplarily, within the target duration, the first resource includes a time domain resource unit with an index value of a first preset value. Taking the time domain resource unit as a time domain symbol as an example, when the subcarrier spacing for transmitting the SSB signal is 120kHz, with a single time slot as the granularity, the time domain symbol indexes that the second resource never occupies are as follows: 0, 1, 12, and 13. Therefore, the first preset value includes one of the following: 0, 1, 12, or 13. That is, the first resource occupies one of the time domain symbols 0, 1, 12, or 13 in the time slot within the target duration, and does not overlap with the second resource in the time domain, thereby avoiding collision between the first signal and the SSB signal. Specifically, the first preset value can be one of 0, 1, 12, 13, {0, 1}, {12, 13}, where {0, 1} indicates occupying time domain symbol 0 and time domain symbol 1 at the same time. It should be understood that, taking the subcarrier spacing of an SSB signal as 120 kHz as an example, within the target duration (5 ms), when the network device 301 transmits the first signal on time domain symbol 12 in each time slot, there are 40 first intervals, and each first interval is 1 time slot (i.e., 14 symbols). Within the target duration (5 ms), when the network device 301 transmits the first signal on time domain symbol 0 and time domain symbol 1 in each time slot, there are 40 first intervals, and each first interval is 13 time domain symbols.

[0211] For example, see Figure 5a , Figure 5aA schematic diagram of resource distribution is shown. The resource location of the second resource is determined based on Case D of 3GPP TS 38.213. When the number of SSB signals is 64, the SSB signal occupies all candidate SSB positions in the half-frame. In the half-frame, the time domain symbol index of the first resource is 13, that is, there are multiple first resources, and they are time domain symbols with index 13 in each time slot in the first 5 ms. In other words, the network device 301 transmits the first signal on time domain symbol 13 in each time slot within 5 ms. Taking two consecutive time slots as the granularity, the time domain symbol indexes always occupied by the second resource are as follows: 4, 5, 6, 7, 8, 9, 10, 11, 16, 17, 18, 19, 20, 21, 22, 23. In this way, any first resource among the multiple first resources and any second resource among the multiple second resources do not overlap in the time domain. Moreover, when there is a first interval between each two adjacent first signals, the time length of each first interval is the same.

[0212] It should be understood that, still taking the time domain resource unit as a time domain symbol as an example, when the subcarrier spacing for transmitting an SSB signal is 120 kHz, if two adjacent time slots are used as the granularity, the time domain symbol indices that are never occupied by the resource position of the second resource are as follows: 0, 1, 2, 3, 12, 13, 14, 15, 24, 25, 26, 27. Therefore, among every two first preset values, one first preset value includes one of the following: 0, 1, 2, 3, 12, 13, and the other first preset value includes one of the following: 14, 15, 24, 25, 26, 27. In this way, any first resource among the multiple first resources and any second resource among the multiple second resources do not overlap in the time domain, thereby preventing collision between the first signal and the SSB signal. In the case of two adjacent time slots as the granularity, the first signal can be transmitted at equal intervals within the target time length. For example, when the two first preset values ​​are a group selected from 0 and 14, 1 and 15, 12 and 26, 13 and 27, {0 and 1, 14 and 15}, {12 and 13, 26 and 27}, the first interval between the two adjacent first signals is 1 time slot. The first signal may also be transmitted at different intervals within the target time length. For example, when the two first preset values ​​are a group selected from 0 and 15, 1 and 14, 12 and 27, 13 and 26, {0 and 1, 24 and 25}, {12 and 13, 25 and 26}, the first interval between the two adjacent first signals is different, that is, the transmission of the first signal is unequally spaced, but the network device 301 can transmit one first signal in each time slot without colliding with the SSB signal.

[0213] As example 2 of the first implementation, when the resource location density of the second resource is high, the first signal can still maintain a high time domain density within the target duration. The target duration can be described in the relevant description of example 1 above and will not be repeated here.

[0214] In this case, within the target time length, the intervals between two adjacent first signals are not all the same, that is, at least the "interval between two adjacent first signals" is different from the "interval between another two adjacent first signals". In other words, within the target time length, there are multiple first intervals, and the time lengths of at least two first intervals among the multiple first intervals are different. Among them, "there are multiple first intervals" can be found in the relevant description of Example 1 above, and will not be repeated here. For example, with two time slots as the granularity, within the target time length (5ms), when the network device 301 transmits the first signal on time domain symbols 3, 13 and 24 respectively, there are three lengths of first intervals, that is, the first interval between time domain symbol 3 and time domain symbol 13 is 10 time domain symbols, the first interval between time domain symbol 13 and time domain symbol 24 is 11 time domain symbols, and the first interval between time domain symbol 24 and time domain symbol 3 in the next time slot is 7 time domain symbols.

[0215] Exemplarily, within the target duration, the first resource includes a time domain resource unit whose index value is a second preset value. Taking the time domain resource unit as a time domain symbol as an example, when the subcarrier spacing for transmitting an SSB signal is 120kHz, with two consecutive time slots as the granularity, the time domain symbol indexes that are never occupied by the resource position of the second resource are as follows: 0, 1, 2, 3, 12, 13, 14, 15, 24, 25, 26, and 27. Based on this, the value of the second preset value includes the following two possible designs:

[0216] In a first possible design, the second preset value includes at least three of the following: 0, 1, 2, 3, 12, 13, 14, 15, 24, 25, 26, or 27. The difference between any two of the second preset values ​​is greater than or equal to the third preset value. For example, the third preset value can be 6. In this case, the second preset value can be determined based on the second possible design, ensuring that at least one first resource exists in each time slot, meaning that network device 301 transmits at least one first signal in each time slot. Furthermore, the difference between any two of the second preset values ​​is greater than or equal to the third preset value, making the first resources discontinuous in the time domain and, to a certain extent, ensuring uniform distribution of the first resources in the time domain. The second preset value can be at least three, meaning that at least three first resources exist in every two time slots, allowing network device 301 to transmit at least three first signals in every two time slots. In the first example, within the half-frame, there is one first resource in each time slot, meaning that one first signal is transmitted in each time slot. Compared to Example 1, Example 2 improves the time domain density of the first signal, which is beneficial to improving radar detection accuracy. Of course, the value of the third preset value can also be other values, such as the value of the third preset value can be 1, and the second preset value can be one of {0, 2, 14}, {0, 2, 15}, {0, 3, 24}, {0, 3, 27}, {12, 15, 25}, {12, 15, 27}, {12, 24, 27}, {15, 24, 27}. In other words, the network device 301 can transmit two first signals on the resources between the two SSB signals, and the network device 301 can also not transmit the first signal on the resources between the two SSB signals. However, the network device 301 can always transmit three first signals in two time slots to improve the time domain density of the first signal.

[0217] In a second possible design, the number of the second preset values ​​is three, wherein the three second preset values ​​satisfy:

[0218] The first second preset value includes one of the following: 0, 1, 2, or 3.

[0219] The second preset value includes one of the following: 12, 13, 14, or 15.

[0220] The third second preset value includes one of the following: 24, 25, 26, or 27.

[0221] In other words, in two adjacent time slots, the network device 301 transmits a first signal on the resource between the two SSB signals, and the network device 301 can always transmit three first signals in two time slots. Exemplarily, the second preset value can be one of the following: {0, 12, 24}, {1, 13, 25}, {2, 14, 26}, {3, 15, 27}, {0, 13, 24}, {1, 13, 24}, {2, 14, 24}, {3, 13, 27}, {0, 15, 24}, {1, 15, 24}, {2, 15, 24}, or {3, 15, 27}. Taking the second preset value including {0, 12, 24} as an example, the network device 301 transmits the first signal on time domain symbols 0, 12, and 24, respectively.

[0222] That is, the difference between the second preset values ​​is relatively uniform. Accordingly, the distribution of time domain symbols indexed by the second preset value in the time slot is relatively uniform, which enables the first signal to be transmitted as uniformly as possible in the time domain, thereby ensuring the time domain density of the first signal and avoiding collision with the SSB signal.

[0223] Alternatively, the method provided in Example 2 of the first implementation method can also be understood as: when part of the third resource overlaps with the candidate position of the SSB signal, the first resource includes at least: advancing or delaying the resource overlapping with the candidate position of the SSB signal in the third resource by at least one time domain symbol, so as to avoid the network device 301 transmitting the first signal and the SSB signal at the same time, while ensuring that the first resource is evenly distributed as much as possible to ensure radar detection accuracy. For example, Figure 5b For example, according to the transmission period of the first signal, the third resource includes time domain symbol 6. However, time domain symbol 6 is used to carry the SSB signal, so the third resource "time domain symbol 6" is moved forward, such as Figure 5b As shown in the time domain symbol 3 in FIG, the time domain symbol 3 is used to transmit the first signal. Figure 5b For example, according to the transmission period of the first signal, the third resource includes time domain symbol 20. However, time domain symbol 20 still carries the SSB signal, so the third resource "time domain symbol 20" is shifted back, such as Figure 5b As shown in the time domain symbol 24 in FIG, the time domain symbol 24 is used to transmit the first signal. Figure 5b In the illustrated scenario, the third resource includes time domain symbol 27. However, after forward and backward shifting, time domain symbol 3 and time domain symbol 24 are both used to transmit the first signal, and time domain symbol 27 can no longer be used to transmit the first signal. This avoids frequent transmission of the first signal, conserves transmission resources, and keeps close to the original transmission period of the first signal. Of course, time domain symbol 27 can also be used to transmit the first signal to reduce the computational complexity of the network device, but this embodiment of the present application is not limited to this.

[0224] For example, see Figure 5b , Figure 5b A schematic diagram of resource distribution is shown. The resource location of the second resource is determined based on Case D of 3GPP TS 38.213. When the number of SSB signals is 64, within a half-frame, the time-domain symbol indexes of the first resource include 3, 13, and 24, which neither collides with the SSB signal nor ensures that the first signal is transmitted as evenly as possible.

[0225] As example 3 of the first implementation, when the resource location density of the second resource is low, the SSB signal only occupies part of the candidate locations. When the subcarrier spacing of the SSB signal is 120 kHz, the time domain symbol index of the SSB signal satisfies:

[0226] {4,16}+28*n formula (6)

[0227] Among them, n=0, 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 15, 16, 17, 18.

[0228] The resource location density of the second resource is low, which may mean that the number of SSB signals is less than or equal to 32, that is, the number of SSB signals included in an SSB burst is less than or equal to 32, that is, the candidate locations of the SSB signal can support a maximum of 32, that is, in formula (6), the maximum number of values ​​of n is 16. When the candidate locations of the SSB signal are fully occupied, the number of SSB signals is 32, that is, 32 SSB signals are sent within 5 ms.

[0229] In this case, within the target duration, the intervals between two adjacent first signals are not exactly the same. For details, please refer to the description of Example 2 above, which will not be repeated here. For example, within the target duration, the first resource includes a time domain resource unit with an index value of a second preset value. Taking the time domain resource unit as a time domain symbol as an example, with two consecutive time slots as the granularity, the second preset value satisfies the following formula:

[0230] K=7*k-1 Formula (7)

[0231] Wherein, K represents the second preset value, K = 2, 3, 4. That is, the values ​​of the second preset value include 13, 20, and 27. Combining formula (6) and formula (7), it can be seen that, with two adjacent time slots as the granularity, the time domain symbol indexes of the second resource are: 4, 5, 6, 7, 16, 17, 18, and 19. The time domain symbol indexes of the first resource are: 13, 20, and 27. That is, according to the transmission period of the first signal, time domain symbol 6 is used to transmit the first signal. However, time domain symbol 6 is used to send the SSB signal, so time domain symbol 6 is no longer used to transmit the first signal. In other words, within the target time length, the third resource that conflicts with the second resource is no longer used to transmit the first signal. In other words, within the target time length, the first resource is composed of resources in the third resource that do not overlap with the candidate position of the SSB signal.

[0232] For example, see Figure 5c , Figure 5c A schematic diagram of resource distribution is shown. The resource location of the second resource is determined based on the above formula (6). When the number of SSB signals is less than or equal to 32, within a half-frame, with two consecutive time slots as the granularity, the time domain symbol indexes of the first resource include 13, 20, and 27.

[0233] That is to say, taking the transmission period of the first signal as 7 time domain symbols as an example, when the transmission position of the first signal overlaps with the transmission position of the SSB signal (that is, the second resource), the first signal is discarded, and the network device 301 does not transmit the first signal, that is, the value of the second preset value does not include 6, thereby avoiding the collision between the first signal and the SSB signal, and ensuring the time domain density of the first signal.

[0234] It should be noted that, outside the target duration of the first implementation method, the SSB signal is no longer sent. In other words, outside the target duration, there is no second resource. The first signal can maintain the original transmission period. That is, the time interval between two adjacent first signals within the target duration is different from the time interval between two adjacent first signals outside the target duration. Outside the target duration, when the interval between two adjacent first signals in the at least one first signal is recorded as the second interval, there are multiple second intervals, and the time lengths of the multiple second intervals are the same, but different from the time length of the first interval. When there are multiple first intervals, the second interval is different from at least one first interval. Among them, the second interval is multiple, which means that the network device 301 transmits multiple first signals outside the target duration, and there is a second interval between each two adjacent first signals. In this way, the number of second intervals is multiple. Outside the target duration, the first resource includes a time domain resource unit with an index value of the preset value 1. In the case where the time domain resource unit is a time domain symbol, the value of the preset value 1 may include: 6, 13, see for details. Figure 5a 、 Figure 5b and Figure 5c shown.

[0235] It should be understood that in the embodiments of the present application, only the transmission period of the first signal of 7 symbols is used as an example for introduction. When the transmission period of the first signal is other time lengths, in addition to the target time length, the resource location of the first resource can also be designed according to other intervals to meet the transmission requirements of the first signal in different scenarios. The embodiments of the present application do not limit this.

[0236] As a second implementation, the second resource is determined based on the first resource. That is, while the transmission period of the first signal remains unchanged, the candidate position of the SSB signal is adjusted to obtain the second resource, so that the first resource and the second resource do not overlap in the time domain. The following two examples are introduced:

[0237] As an example of the second implementation, when the resource location density of the second resource is low, the SSB signal only occupies some candidate locations. When the subcarrier spacing for transmitting the SSB signal is 120 kHz, two possible designs for the second resource are introduced:

[0238] In a first possible design, within the target duration, the second resource includes a time domain resource unit whose index value is a fourth preset value, and the fourth preset value satisfies the following formula:

[0239]

[0240] Wherein, M represents the fourth preset value, N is an integer, and 0≤N≤27, and k is a positive integer.

[0241] From formula (8), it can be seen that when the transmission period of the first signal is 7 time domain symbols, the time domain symbol index of the first resource satisfies: 7*k-1. In the process of N traversing 28 integers (i.e., from 0 to 27), the time domain symbol index carrying the SSB signal is not equal to the time domain symbol index of the first resource, thereby avoiding overlap between the first resource and the second resource in the time domain.

[0242] Exemplarily, with two adjacent time slots as the granularity, the time domain symbol indexes of the first resource include: 6, 13, 20, 27. For example, when N = 0, the time domain symbol indexes of the second resource include: 0, 1, 2, 3, none of which are equal to the time domain symbol index of the first resource. Therefore, the time domain symbols {0, 1, 2, 3} can be used as the second resource for sending SSB signals. For another example, when N = 3, the time domain symbol indexes of the second resource include: 3, 4, 5, 6. In this case, one of the value "6" in the time domain symbol index of the second resource is equal to the time domain symbol index of the first resource. Therefore, the time domain symbols {3, 4, 5, 6} cannot be used as the second resource and are not used to send SSB signals.

[0243] It should be understood that in the first possible design, only the transmission period of the first signal is 7 time domain symbols as an example for introduction. When the transmission period of the first signal is other time lengths, such as the transmission period of the first signal is T time domain symbols, the above formula (8) can be replaced by:

[0244]

[0245] Among them, M represents the fourth preset value, T is the transmission period of the first signal, N is an integer, and 0≤N≤27, k is a positive integer. That is to say, when the transmission period of the first signal is T time domain symbols, the time domain symbol index of the first resource satisfies: T*k-1. In the process of N traversing 28 integers (i.e., from 0 to 27), the time domain symbol index carrying the SSB signal is not equal to the time domain symbol index of the first resource, that is, the time domain symbol index of the second resource (i.e., the time domain symbol index M, M+1, M+2, M+3 of the second resource) is not equal to the time domain symbol index value of the first resource, thereby avoiding the first resource and the second resource from overlapping in the time domain.

[0246] Exemplarily, taking two adjacent time slots as the granularity, taking T=8 as an example, the time domain symbol indexes of the first resource include: 7, 15, 23. For example, when N=0, the time domain symbol indexes of the second resource include: 0, 1, 2, 3, none of which are equal to the time domain symbol index of the first resource. Therefore, the time domain symbols {0, 1, 2, 3} can be used as the second resource for sending SSB signals. For another example, when N=4, the time domain symbol indexes of the second resource include: 4, 5, 6, 7. In this case, one of the time domain symbol indexes of the second resource, "7", is equal to the time domain symbol index of the first resource. Therefore, the time domain symbols {4, 5, 6, 7} cannot be used as the second resource and are not used to send SSB signals.

[0247] In a second possible design, within the target duration, the second resource includes a time domain resource unit whose index value is a fourth preset value, and the fourth preset value satisfies the following formula:

[0248]

[0249] Wherein, M represents the fourth preset value, and N includes at least two of the following values: 0, 1, 2, 7, 8, 9, 14, 15, 16, 21, 22, or 23. Figure 1As can be seen from the introduction, an SSB signal occupies four time domain symbols. Therefore, the difference between any two items in the fourth preset value is greater than 4 to avoid overlapping of resources occupied by SSB signals. Exemplarily, the fourth preset value can be one of the following: {0, 7}, {0, 8}, {0, 9}, {0, 22}, {1, 7}, {1, 8}, {1, 9}, {1, 22}, {1, 23}, {1, 8, 16}, or {2, 9, 16}. It should be understood that when the difference between any two items in the fourth preset value is greater than 4, the value of the fourth preset value can be taken from the above values ​​(i.e., 0, 1, 2, 7, 8, 9, 14, 15, 16, 21, 22, or 23).

[0250] For example, see Figure 5d , Figure 5d A schematic diagram of resource distribution is shown. Taking two time slots as the granularity, when N includes 8 and 16, the resource position of the second resource (i.e., the position carrying the SSB signal) includes time domain symbols 8, 9, 10, 11, 16, 17, 18, and 19, as shown in FIG. Figure 5d As shown, the first signal transmitted by the network device 301 does not overlap with any of the first resources. In this way, the first signal transmitted by the network device 301 does not collide with the SSB signal.

[0251] As an example 2 of the second implementation, when the resource location density of the second resource is high, the SSB signal occupies all candidate locations in the half frame. When the subcarrier spacing of the SSB signal is 120kHz, the time domain symbol index of the SSB signal satisfies:

[0252] {2, 8, 16, 22}+28*n formula (11)

[0253] Among them, n=0, 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 15, 16, 17, 18.

[0254] For example, in Figure 5e In the case of n=0, the SSB signal identified by index 0 is the first SSB signal in the half-frame, and the index of the time domain symbol it occupies is 2 to 5. The SSB signal identified by index 1 is the second SSB signal in the half-frame, and the index of the time domain symbol it occupies is 8 to 11. The SSB signal identified by index 2 is the third SSB signal in the half-frame, and the index of the time domain symbol it occupies is 16 to 19. The SSB signal identified by index 3 is the fourth SSB signal in the half-frame, and the index of the time domain symbol it occupies is 22 to 25.

[0255] That is, with two adjacent time slots as the granularity, when the transmission period of the first signal is 7 time domain symbols, the time domain symbol indexes of the first resource include: 6, 13, 20, and 27. For example, in combination with formula (4), when the first time domain symbol index is 4, the time domain symbol indexes of the second resource include: 4, 5, 6, and 7. That is, the value "6" in the time domain symbol index of the second resource is equal to the time domain symbol index of the first resource, that is, it overlaps with the first resource. Therefore, "4" is adjusted to "2", as shown in formula (11). In this way, the second resource with the first time domain symbol index 2 includes: time domain symbol 2, time domain symbol 3, time domain symbol 4, and time domain symbol 5, which does not overlap with the first resource. For another example, combined with formula (4), when the first time domain symbol index is 20, the time domain symbol index of the second resource includes: 20, 21, 22, 23, that is, the value "20" in the time domain symbol index of the second resource is equal to the time domain symbol index of the first resource, that is, it overlaps with the first resource, so "20" is adjusted to "22", as shown in formula (11). In this way, the second resource with the first time domain symbol index 22 includes: time domain symbol 22, time domain symbol 23, time domain symbol 24 and time domain symbol 25, which does not overlap with the first resource.

[0256] It should be noted that, in the second implementation, whether within or outside the target duration, the first signal maintains the original transmission period, that is, the time length of the first interval is the same as that of the second interval. When the number of first intervals and second intervals is multiple, each second interval in the multiple second intervals is the same as each first interval in the multiple first intervals. The target duration is composed of at least one time slot where the candidate position of the SSB signal is located. The first interval and the second interval can be referred to the introduction of the first implementation, and will not be repeated here. In the second implementation, the first resource includes a time domain resource unit whose index value is a preset value 1. In the case where the time domain resource unit is a time domain symbol, the value of the preset value 1 may include: 6, 13, such as Figure 5d shown.

[0257] S402: The network device 301 transmits at least one first signal on a first resource.

[0258] Among them, the network device 301 has a perception function, and the first signal is used to detect the attributes of the target. The attributes of the target include at least one of the following: moving speed, position, or shape and size. Exemplarily, if the terminal device 305 is within the detection area of ​​the first signal and the radar cross-section (RCS) is greater than a threshold, then the target detected by the first signal includes the terminal device 305, and the network device 301 can receive the echo signal reflected by the terminal device 305, thereby perceiving the location and other attributes of the terminal device 305. Conversely, if the terminal device 305 is outside the detection area of ​​the first signal, or the RCS is less than or equal to the threshold, the network device 301 cannot receive the echo signal reflected by the terminal device 305, that is, the perception object of the network device 301 does not include the terminal device 305, and it is also impossible to detect the location and other attributes of the terminal device 305. Of course, in addition to the above-mentioned terminal device 305, the target can also be other objects that reflect the echo signal. After the network device 301 receives the echo signal, it can also perceive the attributes of the target.

[0259] The first resource in S402 is the first resource in S401. The first resource in S402 can be determined based on the second resource. See the introduction to the first implementation in S401. The first resource in S402 can also be used to determine the second resource. See the introduction to the second implementation in S402. These details are not repeated here. Each first resource carries a first signal. When there is one first resource, the network device 301 transmits a first signal on the first resource. When there are multiple first resources, the network device 301 transmits a first signal on each of the multiple first resources.

[0260] Exemplarily, the specific implementation process of S402 includes:

[0261] In Example 1, network device 301 transmits at least one first signal on a first resource. For example, if there is one first resource, network device 301 transmits one first signal on the first resource. If there are multiple first resources, network device 301 transmits one first signal on each of the multiple first resources. In this case, the first signal can be implemented as a radar detection signal.

[0262] In Example 2, network device 301 receives at least one first signal on a first resource. For example, if there is one first resource, network device 301 receives one first signal on the first resource. If there are multiple first resources, network device 301 receives one first signal on each of the multiple first resources. In this case, the first signal can be implemented as an echo signal of a radar detection signal.

[0263] In Example 3, network device 301 sends and receives a first signal on a first resource. For example, if there is only one first resource, network device 301 sends and receives the first signal on the first resource. If there are multiple first resources, network device 301 sends and receives the first signal on each of the multiple first resources. In this case, the transmitted first signal may be implemented as a radar detection signal, and the received first signal may be implemented as an echo signal of the radar detection signal.

[0264] Example 4: When there are multiple first resources, the multiple first resources are divided into two parts, and the network device performs one of the three examples (Examples 1 to 3) above on one part of the first resources, and performs another of the three examples (Examples 1 to 3) above on the other part of the first resources. Alternatively, the multiple first resources are divided into three parts, and the network device performs one of the three examples (Examples 1 to 3) above on each part of the first resources.

[0265] For example, S402 is described in two cases:

[0266] As the first case, the first signal carries communication information. Figure 6a Before executing S402, the network device 301 executes S403:

[0267] S403: The network device 301 sends first indication information to the terminal device 305. Correspondingly, the terminal device 305 receives the first indication information from the network device 301.

[0268] The first indication information indicates the index value of the first resource.

[0269] Exemplarily, the first indication information may carry an index value of the first resource. For example, when a single time slot is used as the granularity, the first indication information may use 4 bits to indicate the index value of the first resource. For another example, when two time slots are used as the granularity, the first indication information may use 5 bits to indicate the index value of the first resource. The index value of the first resource can be found in the relevant description of S401 and will not be repeated here.

[0270] Alternatively, the first indication information may also indicate the offset between the first resource and the second resource. The unit of the offset is a time domain symbol, and the value of the offset indicates the number of time domain symbols between the first resource and the second resource. The offset may be represented by a preset number of bits. For example, if the offset is small, such as less than 8 time domain symbols, the first indication information may use 3 bits to indicate the offset. For another example, if the offset is large, such as greater than 8 time domain symbols, the first indication information may use 4 or 5 bits to indicate the offset.

[0271] Exemplarily, the first indication information may be high-layer signaling, such as radio resource control (RRC) signaling, or the first indication information may be physical layer signaling, such as downlink control information (DCI).

[0272] When S403 is executed, S402 is specifically implemented as S402a:

[0273] S402a: The network device 301 sends communication information on the first resource to the terminal device 305. Correspondingly, the terminal device 305 receives the communication information from the network device 301 on the first resource.

[0274] The communication information is carried in the first signal, including but not limited to a physical downlink shared channel (PDSCH), etc. The terminal device 305 obtains the communication information from the first signal through demodulation, decoding, and other processing.

[0275] In the second case, the first signal does not carry communication information. In this case, the network device 301 does not need to execute S403 before executing S402. That is, the network device 301 only needs to transmit the first signal according to the resource location of the first resource.

[0276] For the network device 301, the network device 301 can also send SSB signals, such as Figure 6b Steps shown:

[0277] S404: The network device 301 sends at least one SSB signal on the second resource to the terminal device 305. Accordingly, the terminal device 305 can receive at least one SSB signal from the network device 301 on the second resource.

[0278] The second resource in S404 is the second resource in S401. The second resource in S404 can be used to determine the first resource. See the introduction to the first implementation in S401. The second resource in S404 can also be determined based on the first resource. See the introduction to the second implementation in S402, which will not be repeated here. Each second resource carries an SSB signal. When there is one second resource, the network device 301 sends an SSB signal on the second resource. When there are multiple second resources, the network device 301 sends an SSB signal on each of the multiple second resources.

[0279] For example, S404 is introduced in two cases:

[0280] As the first case, the second resource is determined based on the first resource. For details, see the introduction of the second implementation method in S401. Figure 6b Before executing S404, the network device 301 executes S405:

[0281] S405 : The network device 301 sends second indication information to the terminal device 305 . Correspondingly, the terminal device 305 receives the second indication information from the network device 301 .

[0282] The second indication information indicates the index value of the second resource.

[0283] Exemplarily, the second indication information may carry an index value of the second resource. For example, when a single time slot is used as the granularity, the second indication information may use 4 bits to indicate the index value of the second resource. For another example, when two time slots are used as the granularity, the second indication information may use 5 bits to indicate the index value of the second resource. The index value of the second resource can be found in the relevant description of S401 and will not be repeated here.

[0284] Alternatively, the second indication information may also indicate the offset between the second resource and the candidate position of the SSB signal. The unit of the offset is a time domain symbol, and the value of the offset indicates the number of time domain symbols between the second resource and the candidate position of the SSB signal. The offset may be represented by a preset number of bits. For example, if the offset is small, such as less than 8 time domain symbols, the second indication information may use 3 bits to indicate the offset. For another example, if the offset is large, such as greater than 8 time domain symbols, the second indication information may use 4 or 5 bits to indicate the offset.

[0285] Exemplarily, the second indication information may be high-layer signaling, such as signaling, or the second indication information may be physical layer signaling, such as DCI.

[0286] That is to say, when the resource position of the first resource remains unchanged and the second resource is determined based on the first resource, the network device 301 first indicates the index value of the second resource to the terminal device 305 so that the terminal device 305 receives the SSB signal at the resource position indicated by the second indication information.

[0287] It should be noted that, within a preset duration (such as n seconds) before the terminal device 305 executes S405, the network device 301 sends an SSB signal to the terminal device 305 on known resources. Correspondingly, the terminal device 305 receives the SSB signal from the network device 301 on known resources. The known resources are resources specified based on existing protocols (such as 3GPP TS 38.213). In this way, the terminal device 305 is synchronized with the network device 301 through the SSB signal within the above-mentioned preset duration, and then the terminal device 305 executes S405. In addition, the network device 301 may not execute S405. In this case, the terminal device 305 performs blind detection, that is, scans each time domain symbol. If the SSB signal is transmitted on certain time domain symbols, the terminal device 305 can detect the SSB signal from the network device 301.

[0288] As a second case, the second resource is used to determine the first resource, as detailed in the introduction of the first implementation in S401. In this case, the network device 301 does not need to execute S405 before executing S404.

[0289] It should be noted that after the network device 301 sends indication information (such as the first indication information and the second indication information mentioned above) to the terminal device 305, if the terminal device 305 receives the indication information, the terminal device 305 can send an acknowledgement (ACK) to the network device 301. Conversely, if the terminal device 305 does not receive the indication information, the terminal device 305 sends a negative acknowledgement (NACK) to the network device 301. In addition, in the half frame in which the SSB signal is transmitted, the distribution of the first resource is consistent. Even if in the half frame in which the SSB signal is transmitted, a part of the time slots includes the candidate position of the SSB signal, and another part of the time slots does not include the candidate position of the SSB signal, the distribution of the first resource in the two time slots is still consistent, so that the network device 301 always transmits the first signal in a fixed pattern, thereby avoiding frequent changes in the resource position of the first signal and simplifying the complexity of the network device 301 in determining the first resource.

[0290] Understandably, Figure 6a and Figure 6b The methods shown can be implemented individually or in combination, and this application does not impose any restrictions on this.

[0291] The above descriptions are all introduced by taking the example that the first resource and the second resource do not overlap in the time domain to avoid interference between signals. Of course, when the first resource and the second resource overlap in the time domain, the non - overlap of the first resource and the second resource in the frequency domain can also avoid interference between signals. The embodiment of the present application also provides another signal transmission method. The technical concept of this signal transmission method is as follows: The network device determines the first resource. Among them, the first resource and the second resource overlap in the time domain and do not overlap in the frequency domain, and the second resource is used to transmit communication signals, and there is a corresponding relationship between the first resource and the second resource. Then, the network device transmits at least one first signal on the first resource. In this way, the first signal and the communication signal are transmitted in a frequency - division multiplexing manner, so that the first signal and the communication signal do not collide and do not interfere with each other, thereby improving the communication efficiency of the system.

[0292] Among them, the fact that there is a corresponding relationship between the first resource and the second resource may mean that in a preset number of frequency - domain resource units, there is a corresponding relationship in resource positions between the first resource and the second resource. For example, the number of the first resource and the second resource is the same and they correspond one by one. Or, the number of the first resource is different from the number of the second resource, and one of the multiple first resources corresponds to one of the multiple second resources. For example, taking the frequency - domain resource unit as RB, in the same system bandwidth, the number of the first resource is multiple, and each first resource occupies the RB with index x1. The number of the second resource is multiple, and each second resource occupies the RB with index a1. Among them, x1 < a1. x1 is the index of the X RBs with the smallest frequency in the system bandwidth, and X is a positive integer. Taking the communication signal as the SSB signal, it can be known that one SSB signal occupies 20 RBs. x1 < a1 can be understood as that the RB index corresponding to the first resource is less than the index of each of the 20 RBs corresponding to the second resource. Again, still taking the frequency - domain resource unit as RB, in the same system bandwidth, the number of the first resource is multiple, and each first resource occupies the RB with index y1. The number of the second resource is multiple, and each second resource occupies the RB with index a1. Among them, a1 < y1. y1 is the index of the Y RBs with the largest frequency in the system bandwidth, and Y is a positive integer. Taking the communication signal as the SSB signal, it can be known that one SSB signal occupies 20 RBs. a1 < y1 can be understood as that the RB index corresponding to the first resource is greater than the index of each of the 20 RBs corresponding to the second resource. The description of the first signal can be referred to the introduction in the signal transmission method 400, and will not be elaborated here. Figure 1 As shown, the embodiment of the present application provides a signal transmission method 700. This signal transmission method 700 is applied in the signal transmission process of radar - communication integration. Refer to Figure 1 As shown, the embodiment of the present application provides a signal transmission method 700. This signal transmission method 700 is applied in the signal transmission process of radar - communication integration. Refer to

[0293] As Figure 7 shown, the embodiment of the present application provides a signal transmission method 700. This signal transmission method 700 is applied in the signal transmission process of radar - communication integration. Refer to Figure 7 , the method comprises the following steps:

[0294] S701: The network device 301 determines a first resource.

[0295] The first resource and the second resource overlap in the time domain but do not overlap in the frequency domain. The number of the first resources is one or more, and any two adjacent first resources among the multiple first resources may be continuous or discontinuous in the frequency domain, such as Figure 8a As shown. Each first resource can occupy one or more frequency domain resource units in the frequency domain. Specifically, the network device 301 can determine one or more first resources. It can be understood that the first resource and the second resource overlap in the time domain and do not overlap in the frequency domain. When the number of first resources and the number of second resources are both multiple, one first resource in the multiple first resources and one second resource in the multiple second resources overlap in the time domain and do not overlap in the frequency domain. Among them, the number of first resources and the number of second resources can be the same, and the first resource in the multiple first resources and the second resource in the multiple second resources have a one-to-one correspondence, that is, one first resource in the multiple first resources and one second resource in the multiple second resources overlap in the time domain and do not overlap in the frequency domain. Alternatively, the number of first resources and the number of second resources can be different, such as at least two first resources in the multiple first resources correspond to one second resource in the multiple second resources, such as two first resources in the multiple first resources and one second resource in the multiple second resources overlap in the time domain, and the above two first resources and the above one second resource do not overlap in the frequency domain.

[0296] Each second resource may be 20 consecutive RBs in the frequency domain, see Figure 1 The number of second resources can be multiple. Among the multiple second resources, any two adjacent second resources can occupy RBs with the same index in the frequency domain, or they can occupy RBs with different indexes. This embodiment of the present application does not limit this. In the embodiment of the present application, an example is used to introduce that any two adjacent second resources can occupy RBs with the same index in the frequency domain.

[0297] Exemplarily, the first resource includes a frequency domain resource unit indicated by a first index value, and the second resource includes a frequency domain resource unit indicated by a second index value. When the frequency domain resource unit is implemented as an RB, the system bandwidth includes 90 RBs, and the index values ​​are 0 to 89. Exemplarily, the value of the first index value includes one of the following: 45, 46, 47, {48, 49}, or {50, 51, 52}, etc. Among them, {48, 49} indicates that the first resource includes an RB with an index of 48 and an RB with an index of 49. Taking the communication signal as an SSB signal as an example, the value of the second index value includes one of the following: {0 to 19}, {1 to 20}, {2 to 21}, or {3 to 22}, etc. Among them, {0 to 19} indicates that the second resource includes RBs with indexes of 0 to 19. It should be understood that as long as any value in the first index value is different from all values ​​in the second index value, the first index value and the second index value can also have other values, and this embodiment of the present application is not limited to this. The following describes the first index value and the second index value in two implementation methods:

[0298] As a first implementation, the first index value is smaller than the second index value, that is, each value in the first index value is smaller than all values ​​in the second index value.

[0299] For example, see Figure 8a Taking a system bandwidth of 60 RBs as an example, a frequency domain resource unit may include one RB. The first resource occupies 20 RBs, and the first index value ranges from 0 to 19. The first index value may be recorded as {0 to 19}. That is, the first index value indicates the 20 RBs with the smallest frequency in the system bandwidth. When the communication signal is implemented as an SSB signal, the number of RBs occupied by the second resource is 20. If the second index value ranges from 30 to 49, the second index value may be recorded as {30 to 49}.

[0300] Alternatively, a frequency domain resource unit may include 20 RBs, that is, every 20 RBs are recorded as a frequency domain resource unit. In this case, taking the system bandwidth including 10 frequency domain resource units (that is, the system bandwidth includes 200 RBs) as an example, the indexes of the frequency domain resource units are 0 to 9. The first resource occupies one frequency domain resource unit (that is, the first resource occupies 20 RBs), and the frequency domain resource unit occupied by the first resource is located in one or more frequency domain resource units among the first N frequency domain resource units of the system bandwidth, where N is a positive integer. If the value of the first index value is 0, the value of N can be 3. That is, the first resource includes one frequency domain resource unit among the first three frequency domain resource units of the system bandwidth. The first N frequency domain resource units of the system bandwidth can be understood as all frequency domain resource units in the system bandwidth arranged in order from low to high frequency. In this case, the first N frequency domain resource units of the system bandwidth can refer to the N frequency domain resource units with the smallest frequencies in the system bandwidth. In other words, the first resource occupies the X frequency domain resource units with the smallest frequencies in the system bandwidth, where X is a positive integer and X≤N. When the communication signal is implemented as an SSB signal, the second resource occupies one frequency domain resource unit (i.e., the second resource occupies 20 RBs), and the second index value may include 7. It should be understood that one frequency domain resource unit may also include other numbers of RBs, such as 10 RBs, and the embodiment of the present application does not limit the number of RBs in the frequency domain resource unit.

[0301] As a second implementation, the first index value is greater than the second index value, that is, each value in the first index value is greater than all values ​​in the second index value.

[0302] For example, see Figure 8b , still taking the system bandwidth of 60 RBs as an example, a frequency domain resource unit may include one RB. The first resource occupies 20 RBs, and the first index value ranges from 40 to 59, and the first index value may be recorded as {40 to 59}. That is, the first index value indicates the 20 RBs with the largest frequencies in the system bandwidth. When the communication signal is implemented as an SSB signal, the number of RBs occupied by the second resource is 20, and the second index value ranges from 0 to 19, and the second index value may be recorded as {0 to 19}.

[0303] Alternatively, one frequency domain resource unit may include 20 RBs. In this case, taking the system bandwidth including 10 frequency domain resource units (i.e., the system bandwidth includes 200 RBs) as an example, the index of the frequency domain resource unit is 0 to 9. The first resource occupies one frequency domain resource unit, and the frequency domain resource unit occupied by the first resource is located in one or more frequency domain resource units among the last N frequency domain resource units of the system bandwidth, where N is a positive integer. If the value of the first index value is 9, the value of N can be 3. That is to say, the first resource includes one frequency domain resource unit among the last three frequency domain resource units of the system bandwidth. Among them, the last N frequency domain resource units of the system bandwidth can be understood as all frequency domain resource units in the system bandwidth arranged in order from low to high frequency. In this case, the last N frequency domain resource units of the system bandwidth can refer to the N frequency domain resource units with the largest frequency in the system bandwidth. In other words, the first resource occupies the Y frequency domain resource units with the largest frequency in the system bandwidth, where Y is a positive integer and Y≤N. When the communication signal is implemented as an SSB signal, the second resource occupies a frequency domain resource unit, the second index value includes 9, and the second index value can be recorded as 9.

[0304] It should be understood that when the first signal and the communication signal are sent in a frequency division multiplexing manner, the number of frequency domain resource units occupied by the first signal can be one or more, and the embodiments of the present application do not limit this. Figure 8a and Figure 8b Only the example of the first resource occupying 20 RBs is used for introduction. The number of frequency domain resource units occupied by the first resource may have other values, which is not limited in the embodiment of the present application. The first signal may be transmitted at equal intervals or at unequal intervals in the time domain, which is not limited in the embodiment of the present application. When the communication signal is implemented as an SSB signal, the distribution of the SSB signal in the time domain can be referred to the introduction of the five cases (such as Case A, Case B, Case C, Case D, and Case E) shown in the glossary section, which will not be repeated here.

[0305] Optionally, the bandwidth of the first signal is described as follows: In one scenario, the sum of the bandwidth of the first signal and the bandwidth of the communication signal is less than or equal to the system bandwidth. For example, the system bandwidth is 60 RBs and the bandwidth of the communication signal is 20 RBs. In this case, the bandwidth of the first signal can be 40 RBs or 35 RBs. Of course, the bandwidth of the first signal can also have other values, such as 20 RBs, and this is not limited in this embodiment of the present application. In other words, the bandwidth of the first signal is determined based on the system bandwidth and the bandwidth of the communication signal. In this way, the first signal and the communication signal occupy different frequency domain resource units within the system bandwidth. Therefore, even if the network device transmits the first signal and the communication signal simultaneously, since they are transmitted using frequency division multiplexing, there will be no interference between the signals. In another scenario, the bandwidth of the first signal is equal to the system bandwidth. For example, the system bandwidth is 60 RBs. In this case, the bandwidth of the first signal can be 60 RBs. Of course, the system bandwidth can also have other values, such as 100 RBs. Accordingly, the bandwidth of the first signal is 100 RBs, and this embodiment of the present application does not limit the size of the system bandwidth.

[0306] S702: The network device 301 transmits at least one first signal on a first resource.

[0307] The implementation process of S702 can refer to the introduction of S402 and will not be repeated here.

[0308] In the signal transmission method 700 of the embodiment of the present application, the first resource determined by the network device is a resource that overlaps with the second resource in the time domain but does not overlap with the second resource in the frequency domain, and a corresponding relationship exists between the first and second resources in terms of resource location. In this way, the first signal and the communication signal are transmitted via different frequency domain resources, preventing collision and interference between the first signal and the communication signal, thereby improving system communication efficiency.

[0309] In some embodiments, the first signal may or may not carry communication information. The following describes two cases:

[0310] As the first case, the first signal carries communication information. Figure 9a Before executing S702, the network device 301 executes S703:

[0311] S703 : The network device 301 sends instruction information 1 to the terminal device 305 . Correspondingly, the terminal device 305 receives the instruction information 1 from the network device 301 .

[0312] The indication information 1 indicates the resource location of the first resource, such as the resource location of the first resource in the frequency domain.

[0313] Exemplarily, the indication information 1 may carry an index value of the first resource, i.e., a first index value. For example, the indication information 1 may use a preset number of bits to indicate the first index value. The first index value can be described in the relevant introduction of S701 and will not be repeated here.

[0314] Alternatively, indication information 1 may also indicate the offset between the first resource and the second resource. The unit of the offset is a frequency domain resource unit, such as an RB, and the value of the offset indicates the number of frequency domain resource units between the first resource and the second resource. The offset may be represented by a preset number of bits. For example, if the offset is small, such as less than 8 RBs, indication information 1 may use 3 bits to indicate the offset. For another example, if the offset is large, such as greater than 8 RBs, indication information 1 may use 4 or 5 bits to indicate the offset.

[0315] Optionally, the indication information 1 further indicates a resource location of a fourth resource, such as a resource location of the fourth resource in the frequency domain, wherein the fourth resource does not overlap with the second resource in the time domain, and the fourth resource is also used to transmit the first signal.

[0316] Exemplarily, indication information 1 may carry the index value of the fourth resource. When the system bandwidth is 60 RBs, one frequency domain resource unit includes one RB. For example, the index value corresponding to the frequency domain resource unit occupied by the fourth resource may range from 0 to 59. That is, when the first signal does not collide with a communication signal, the bandwidth of the first signal is equal to the system bandwidth. Exemplarily, indication information 1 further indicates that the index value of the fourth resource ranges from 0 to 59. For another example, the index value corresponding to the frequency domain resource unit occupied by the fourth resource may range from 0 to 35. That is, when the first signal does not collide with a communication signal, the first signal occupies a portion of the system bandwidth. Exemplarily, indication information 1 further indicates that the index value of the fourth resource ranges from 0 to 35. When the system bandwidth is 100 RBs, one frequency domain resource unit includes 20 RBs. For example, the index value corresponding to the frequency domain resource unit occupied by the fourth resource may range from 0 to 4. That is, when the first signal does not collide with a communication signal, the bandwidth of the first signal is equal to the system bandwidth. Exemplarily, indication information 1 further indicates that the index value of the fourth resource ranges from 0 to 4. For another example, the index value corresponding to the frequency domain resource unit occupied by the fourth resource may include 0 to 3. That is, when the first signal does not collide with the communication signal, the first signal occupies a portion of the system bandwidth. Exemplarily, the indication information 1 further indicates that the index value of the fourth resource includes 0 to 3.

[0317] In the case where the first signal carries communication information, see Figure 9b Before executing S702, the network device 301 may further execute S704:

[0318] S704 : The network device 301 sends the instruction information 2 to the terminal device 305 . Correspondingly, the terminal device 305 receives the instruction information 2 from the network device 301 .

[0319] The indication information 2 at least indicates the bandwidth. The following two examples are used to introduce:

[0320] In example 1, instruction 2 indicates the following two items:

[0321] The first item, the sum of the first bandwidth and the bandwidth of the communication signal is less than or equal to the system bandwidth. Among them, the first bandwidth is the bandwidth when the first signal and the communication signal overlap in the time domain. For example, the system bandwidth is still 60 RBs. The bandwidth of the communication signal is 20 RBs. In this case, the first bandwidth can be 40 RBs or 35 RBs. Of course, the first bandwidth can also have other values, such as 20 RBs, which is not limited in this embodiment of the present application. That is to say, when the bandwidth of the first signal is the system bandwidth, the network device indicates to the terminal device the first bandwidth when the first signal overlaps with the communication signal. Accordingly, the terminal device receives the first signal based on the first bandwidth indicated by the indication information 2.

[0322] The second item, the second bandwidth is equal to the system bandwidth. Among them, the second bandwidth is the bandwidth when the first signal and the communication signal do not overlap in the time domain. For example, the system bandwidth is still 60 RBs. In this case, the second bandwidth can be 60 RBs. Of course, the system bandwidth can also have other values, such as 100 RBs. Accordingly, the second bandwidth is 100 RBs, and the embodiment of the present application does not limit the size of the system bandwidth. That is to say, when the bandwidth configured by the first signal is the system bandwidth, the network device indicates to the terminal device the second bandwidth when the first signal and the communication signal do not overlap. Accordingly, the terminal device receives the first signal based on the second bandwidth indicated by the indication information 2.

[0323] Example 2, instruction 2 indicates the following two items:

[0324] First, the bandwidth of the first signal is equal to the system bandwidth. For example, the system bandwidth is still assumed to be 60 RBs. In this case, the bandwidth of the first signal can be 60 RBs. Of course, the system bandwidth can also have other values, such as 100 RBs. Accordingly, the bandwidth of the first signal is 100 RBs. This embodiment of the application does not limit the size of the system bandwidth.

[0325] Second, the network device does not transmit the first signal on the second resource. In this case, if the first signal and the communication signal overlap in the time domain, the first resource includes frequency domain resource elements in the system bandwidth excluding the second resource. For example, assuming the system bandwidth is 60 RBs and the communication signal bandwidth is 20 RBs, the first resource includes 40 RBs. Of course, the system bandwidth can also have other values, such as 100 RBs. Accordingly, the first resource includes 80 RBs. This embodiment of the application does not limit the size of the system bandwidth. The second resource, which carries the communication signal, is used to transmit the communication signal, not the first signal. That is, if the first signal and the communication signal overlap in the time domain, the network device 301 does not transmit the first signal on the second resource and transmits the first signal to the terminal device 305 on the first resource. Accordingly, the terminal device 305 does not receive the first signal on the second resource and receives the first signal from the network device 301 on the first resource. If the first signal and the communication signal do not overlap in the time domain, the first signal occupies all resources of the system bandwidth. That is, when the first signal and the communication signal do not overlap in the time domain, the network device 301 sends the first signal to the terminal device 305 over the full bandwidth of the system bandwidth. Accordingly, the terminal device 305 receives the first signal from the network device 301 over the full bandwidth of the system bandwidth.

[0326] Exemplarily, the indication information (such as indication information 1 in the above S703 or indication information 2 in S704) may be high-layer signaling, such as RRC signaling, or the indication information may be physical layer signaling, such as DCI.

[0327] It should be understood that the network device 301 executes S703 but does not execute S704, and accordingly, the terminal device 305 executes S703 but does not execute S704. Alternatively, the network device 301 executes S704 but does not execute S703, and accordingly, the terminal device 305 executes S704 but does not execute S703. In this way, the terminal device 305 can receive at least one first signal based on indication information 1 or indication information 2. In the case where the terminal device 305 executes S704, since the terminal device 305 is able to determine the resource location of the second resource, the terminal device 305 determines the resource location of the first resource, or the location range of the first resource, based on the system bandwidth and the resource location of the second resource. Afterwards, the terminal device 305 receives the first signal based on the resource location of the first resource, or the location range of the first resource.

[0328] When S703 or S704 is executed, the specific implementation process of S702 can refer to the introduction of S402a and will not be repeated here.

[0329] It should be noted that after the network device 301 sends indication information to the terminal device 305 (such as indication information 1 in S703 above, or indication information 2 in S704), if the terminal device 305 receives the indication information, the terminal device 305 can send ACK or NACK to the network device 301. For details, please refer to the introduction in the signal transmission method 400.

[0330] In the second case, the first signal does not carry communication information. In this case, the network device 301 does not need to execute S703 and S704 before executing S702. That is, the network device 301 only needs to transmit the first signal according to the resource location of the first resource.

[0331] Network device 301 is also capable of sending communication signals. That is, network device 301 sends at least one communication signal to terminal device 305 on the second resource. Accordingly, terminal device 305 can receive at least one communication signal from network device 301 on the second resource. Implicitly, network device 301 does not send the first signal to terminal device 305 on the second resource. Accordingly, terminal device 305 does not receive the first signal from network device 301 on the second resource.

[0332] That is, the network device transmits the first signal and the communication signal in a frequency division multiplexing manner.

[0333] It should be understood that in the signal transmission method 400 and the signal transmission method 700 in the embodiments of the present application, only the subcarrier spacing of 120kHz for transmitting SSB signals is used as an example for introduction. Of course, the subcarrier spacing can also be replaced with other values, and the core idea of ​​the signal transmission method in the embodiment of the present application is also applicable. In the signal transmission method 400 and the signal transmission method 700 in the embodiments of the present application, the system bandwidth may refer to the bandwidth supported by a carrier in the NR system. For example, the carrier bandwidth of the NR system may be one of 10MHz, 15MHz, 20MHz, 50MHz, 100MHz and 400MHz. Among them, a carrier can be configured with multiple partial bandwidths (bandwidth part, BWP). Of course, the system bandwidth may also refer to the bandwidth supported by a serving cell in the LTE system, which is not limited in the embodiments of the present application.
