Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a communication method and device. Background Art

[0002] With the development of the fifth generation (5G) IoT services (such as wearables, industrial sensors, and video surveillance), research on reduced capability (RedCap) devices has gradually attracted more and more attention. 5G RedCap devices have advantages in terms of low terminal complexity, and can effectively balance the capabilities of 5G large bandwidth, high speed, wide connection, and low latency in terms of bandwidth, power consumption, antenna design, and cost, meet the networking needs of differentiated industries, and support a larger IoT market.

[0003] However, precisely because of the simplified functions, the bandwidth capacity of the RedCap device has been cut from 100MHz of ordinary 5G terminal devices to 20MHz. At present, in order to achieve high ranging resolution of the RedCap device, frequency hopping is usually used to send reference signals to achieve ranging. However, when the reference signal needs to be sent in multiple time windows, random phase errors will be introduced between adjacent time windows, resulting in a decrease in device performance. Therefore, how to avoid the phase error introduced by frequency hopping and improve system performance is an important issue that needs to be solved urgently. Summary of the invention

[0004] The present application provides a communication method and device, which can avoid random phase errors introduced by frequency hopping between adjacent time windows and improve system performance.

[0005] In a first aspect, an embodiment of the present application provides a communication method, which can be executed by a first device or by a component of the first device (such as a chip, a chip system, or a circuit). This application is not limited to this. For ease of description, the following is an illustration of execution by the first device. The method includes: sending N groups of signals, the N groups of signals are respectively located in N time windows, each group of signals in the N groups of signals includes M signals, the Mth signal in the i-th group of signals and the 1st signal in the i+1-th group of signals occupy the same frequency domain resources, and the Mth signal in the i-th group of signals i The signal is located at M i resources, the M i The time domain resources of the resources are different. i The frequency domain resource of any one of the resources is L i One of the frequency domain resources, the L iTwo adjacent frequency-domain resources in a frequency-domain resource partially overlap, where the i-th group of signals and the (i + 1)-th group of signals belong to the N groups of signals, and i is any integer greater than or equal to 1 and less than or equal to N - 1, and N or M or M i is any integer greater than or equal to 2, L i is greater than or equal to 2 and less than or equal to M i of any integer.

[0006] Among them, the time length occupied by each time window can refer to the time interval between the start time of the previous time window and the start time of the next time window, or the time interval between the end time of the previous time window and the end time of the next time window, or the time interval between the middle time of the previous time window and the middle time of the next time window. This application does not make any limitations in this regard.

[0007] It should be noted that a signal being located within a time window or transmitting a signal within a time window can mean that the signal is located within a partial time period within the time window or transmits a signal within a partial time period within the time window. The signal can be concentrated within a certain period of time within the time window, such as the first few time-domain resources. This application does not make any limitations. This application's solution does not limit whether the time lengths occupied by the N time windows are the same. It can be understood that when the time lengths of the N time windows are the same, the solution of this application can be applied to scenarios where frequency-hopping signals are transmitted periodically. The frequency-hopping signals are transmitted periodically in units of the cycle duration. At this time, there can be multiple time windows in the time domain, and the time length corresponding to each time window can be understood as this cycle duration. In this application, one of the above-mentioned multiple time windows can also be referred to as a cycle. Therefore, the N time windows can be understood as N cycles. Based on the above solution, by setting the frequency-domain resources of the last resource of the previous time window and the first resource of the next time window in adjacent time windows to be the same, the transmitting device does not need to perform frequency hopping when transmitting the last signal of the previous time window and the first signal of the next time window, thereby being able to avoid additional random phase errors introduced by frequency hopping between adjacent time windows. At the same time, setting any two adjacent frequency-domain resources among the multiple frequency-domain resources in each time window to partially overlap can facilitate the estimation of the random phase error introduced by frequency hopping within each time window.

[0129] Next, the technical solutions in the present application will be described in conjunction with the accompanying drawings.

As Figure 1 shown, the communication system of the embodiments of the present application may include a network device 100 and at least one terminal device (such as Figure 1 101 - 105 in). The network device may include 1 antenna or multiple antennas. Additionally, the network device may additionally include a transmitter chain and a receiver chain, which can be understood by those of ordinary skill in the art to include multiple components related to signal transmission and reception (such as a processor, a modulator, a multiplexer, a demodulator, a demultiplexer, or an antenna, etc.). Figure 1 This is just a simplified schematic diagram for illustration. In addition, the communication system may further include other communication devices, Figure 1 which are not shown in.

[0131] The communication system architecture 10 applied to the embodiments of the present application is only an example, and the communication system architectures applicable to the embodiments of the present application are not limited thereto. For example, any communication system architecture that can implement the functions of the above-mentioned various devices is applicable to the embodiments of the present application.

[0132] Figure 2 FIG. 4 is a schematic structural diagram of a communication system 20 applicable to the embodiments of the present application. In Figure 2 In the shown wireless communication system, terminal devices can communicate directly with each other without the help of network devices. The interface between terminal devices is called the PC5 interface, which is similar to the Uu interface between a terminal device and a base station. The link between terminal devices is called a sidelink (SL), and a typical application scenario of SL communication is V2X. In V2X, each vehicle is a terminal device, and terminal devices can directly transmit data to each other through SL without passing through the network, which can effectively reduce communication latency.

[0133] The solution of the present application can be applied to communication-sensing integrated scenarios, or sensing scenarios, or positioning scenarios. For example, Figure 1 in the communication-sensing integrated scenario (or sensing scenario or positioning scenario) of self-transmission and other-reception, where the terminal device sends and the network device receives, or, it can also be Figure 2 in the communication-sensing integrated scenario (or sensing scenario or positioning scenario) of self-transmission and other-reception between multiple terminal devices, or, it can also be the self-transmission and self-reception communication-sensing scenario applied to a single terminal device, etc. Among them, the signal for sensing can be a specific reference signal or the communication signal can be used for sensing, which is not limited in the present application.

[0135] The technical solution provided by this application can also be applied to device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-to-machine (M2M) communication, machine type communication (MTC), and Internet of Things (IoT) communication systems or other communication systems.

[0136] As an example, V2X communication can include: vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, vehicle-to-pedestrian (V2P) communication, and vehicle-to-network (V2N) communication. V2V refers to communication between vehicles. V2P refers to communication between a vehicle and a person (including pedestrians, cyclists, drivers, or passengers, etc.). V2I refers to communication between a vehicle and infrastructure, such as a roadside unit (RSU) or a network device. Among them, the RSU includes two types: the terminal type of RSU, which is located by the roadside and is in a non-mobile state, and mobility does not need to be considered; the base station type of RSU, which can provide timing synchronization and resource scheduling for the vehicles communicating with it. V2N refers to communication between a vehicle and a network device. It can be understood that the above is an exemplary description, and the embodiments of this application are not limited thereto. For example, V2X can also include V2X communication based on the NR system in the current 3GPP Rel-16 and subsequent versions, etc.

[0137] As an example, D2D communication can include communication between a programmable logic controller (PLC) and its subordinate devices, such as communication between a PLC and a sensor, or communication between a PLC and an actuator. Among them, the sensor can be, for example, a pressure sensor, a temperature sensor, etc. Among them, the actuator can be, for example, a valve island, a heater, etc. For example, the PLC receives the data measured by all sensors within each cycle time, and at the same time sends execution instructions to the actuator within each cycle time.

[0138] The terminal device in the embodiments of the present application may also be referred to as a user equipment (UE), access terminal, user unit, user station, mobile station, mobile device, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The terminal device may be a device that provides voice / data to users. For example, it may be a handheld device with wireless connection capabilities, in-vehicle device, etc. Currently, some examples of terminals are: mobile phones, tablet computers, laptop computers, palmtop computers, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, or other processing devices connected to a wireless modem, wearable devices, terminal devices in 5G networks, or terminal devices in future evolved public land mobile networks (PLMNs). The embodiments of the present application are not limited thereto.

[0139] By way of example and not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. A wearable device, also known as a wearable intelligent device, is a general term for devices developed by applying wearable technologies to the intelligent design of daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that can be directly worn on the body or integrated into the user's clothes or accessories. A wearable device is not just a hardware device, but also realizes powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable intelligent devices include those with complete functions and large sizes that can achieve complete or partial functions without relying on a smartphone, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to cooperate with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0140] In the embodiments of the present application, the device for implementing the functions of the terminal device may be the terminal device itself or a device capable of supporting the terminal device to implement such functions, such as a chip system or a chip, and this device may be installed in the terminal device. In the embodiments of the present application, the chip system may be composed of chips or may include chips and other discrete devices.

[0141] The network device in the embodiments of the present application can be a device used to communicate with a terminal device. This network device can also be referred to as an access network device or a radio access network device. For example, the network device can be a base station. The network device in the embodiments of the present application can refer to a radio access network (RAN) node (or device) that connects a terminal device to a wireless network.

For example, the RAN node can be a CU, DU, central unit-control plane (CU-CP), central unit-user plane (CU-UP), or RU, etc. The CU and DU can be separately provided, or can also be included in the same network element, such as in the BBU. The RU can be included in a radio frequency device or radio frequency unit, such as included in the RRU, AAU, or RRH. In a possible design, the processing unit used to implement the baseband function in the BBU is called the base band high (BBH) unit, and the processing unit used to implement the baseband function in the RRU / AAU / RRH is called the base band low (BBL) unit. In different systems, the CU (or CU-CP and CU-UP), DU, or RU may also have different names, but those skilled in the art can understand their meanings.For example, the radio access network may also be an open radio access network (O-RAN) architecture. In the ORAN system, the CU may also be referred to as O-CU (Open CU), the DU may also be referred to as O-DU, the CU-CP may also be referred to as O-CU-CP, the CU-UP may also be referred to as O-CU-UP, and the RU may also be referred to as O-RU.

For example, a helicopter or a drone may be configured to act as a mobile base station, and one or more cells may move according to the position of the mobile base station. In other examples, a helicopter or a drone may be configured to be used as a device for communicating with another base station.

[0143] In the embodiments of this application, the device for implementing the functions of the network device may be the network device or a device that can support the network device to implement such functions, such as a chip system or a chip, and this device may be installed in the network device.

The scenarios in which the network device and the terminal device are located are not limited in the embodiments of this application.

[0145] To facilitate the understanding of the embodiments of this application, the terms or technologies involved in this application are briefly described first.

[0146] 1. Time-domain resources and frequency-domain resources

[0147] The network device and the terminal device can sense each other through time-frequency resources. In the embodiments of this application, time-domain resources are, for example, subframes, frames, half subframes or half frames, etc., time slots, sub-time slots, mini-slots, partial slots, orthogonal frequency division multiplexing (OFDM) symbols or single carrier frequency division multiple access (SC-FDMA) symbols, etc.

[0148] The frequency-domain resource can also be replaced by a frequency resource, which represents a resource for carrying frequency-domain data. The frequency-domain resource can be a resource element (RE), or a resource block (RB), or a sub-channel, or a resource pool, or an RB set, or a bandwidth, or a bandwidth part (BWP), or a carrier, or a channel, or an interlaced RB, or an interlaced RE, or a comb, etc.

[0149] Figure 3 FIG. is a schematic diagram of a time-frequency resource applicable to the embodiments of this application. Taking a time slot as the time-domain resource and an RB as the frequency-domain resource as an example, a time slot can include 14 time-domain symbols, and an RB can include 12 subcarriers. A RE can be regarded as the smallest resource unit for data transmission, or in other words, a RE is the smallest resource unit for resource mapping of the data to be transmitted. As Figure 3 shown, a RE corresponds to one symbol in the time domain, such as an OFDM symbol or a discrete fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) symbol. A RE corresponds to one subcarrier in the frequency domain. A RE can be used to map a complex symbol, such as a complex symbol obtained through modulation or a complex symbol obtained through precoding. This application does not limit this. It should be understood that Figure 3This is only a schematic diagram of a possible time-frequency resource provided for ease of understanding, and the present application does not limit the specific form of the time-frequency resource.

[0150] 2. Frequency Hopping (FH)

[0151] In the sensing scenario, the device sends sensing signals with different center frequencies but continuous spectra within several time-domain resources.

[0152] 3. Frequency Hopping Pattern

[0153] The set of time-frequency resources corresponding to different moments can be called a frequency hopping pattern. In the frequency hopping pattern, different time-domain resources may correspond to different frequency-domain resources. The frequency hopping pattern can also be called a frequency hopping pattern.

[0154] The terms involved in the present application are briefly described above and will not be elaborated in the following embodiments. In addition, the above description of the terms is only for ease of understanding and does not limit the protection scope of the embodiments of the present application.

[0155] In the sensing scenario, the distance and speed of the target can be measured by periodically sending a reference signal within a certain bandwidth. For example, to achieve a ranging resolution of 0.3 m, the bandwidth of the sensing signal needs to be at least 500 MHz, which poses a high requirement for the sampling rate of the analog-to-digital converter (ADC) of the UE (that is, to avoid loss of ranging accuracy, the ADC sampling rate of the UE also needs to reach at least 500 MHz). For RedCap devices, due to the limited signal bandwidth they can send, it is difficult to achieve high ranging resolution. Therefore, in order to reduce the requirement for the ADC sampling rate of the UE and at the same time support RedCap devices to achieve high ranging resolution, the current solution uses frequency hopping to send reference signals for ranging, as Figure 4 shown. In the frequency hopping method, since the signal bandwidth within a single symbol is small, the requirement for the ADC sampling rate of the UE in this solution is low. At the same time, this solution also adapts to the signal transmission ability of RedCap devices. At the same time, in the frequency hopping method, since the signal spectra on multiple time-domain resources are continuous and the channel can be considered basically unchanged within the multiple time-frequency resources used to complete a frequency hopping pattern, these signals can be jointly processed to form an equivalent large-bandwidth signal for ranging.

[0156] However, for each frequency hopping in a frequency hopping pattern, various frequency-sensitive devices such as phase locked loop (PLL), low noise amplifier (LNA), power amplifier (PA), etc. will introduce a random phase error between adjacent frequency domain resources, and this random error will lead to a decline in ranging performance. When it is necessary to periodically transmit a reference signal by frequency hopping (i.e., when the frequency hopping pattern appears periodically as described above Figure 4 ), the same random phase error will also be introduced between adjacent periods in multiple frequency hopping periods, resulting in a decline in velocity measurement performance.

[0157] In view of this, the present application provides a communication method and apparatus, which can avoid the random phase error introduced by frequency hopping between adjacent periods in multiple frequency hopping periods. When applied to a sensing scenario, it can improve the performance of the sensing system.

[0158] Figure 5 It is a schematic flowchart of the first communication method 500 provided by an embodiment of the present application. As Figure 5 shown, this schematic flowchart is illustrated by taking the interaction between a first device and a second device as an example. Among them, the steps executed by the first device and / or the second device can be executed by modules or units in the first device and / or the second device. For example, they can be executed by a chip in the first device and / or the second device.

[0159] It should be noted that when the method provided by the present application is applied to a sensing scenario, the N groups of signals or M signals are sensing signals, such as for ranging, positioning, or velocity measurement, etc. The sensing signals can refer to sensing reference signals, or positioning reference signals, or communication signals for sensing, etc. The present application does not make any limitations in this regard. It can be understood that when the method provided by the present application is applied to a self-transmitting and other-receiving sensing scenario, the first device is different from the second device. For example, the first device can be a terminal device, and the second device can be a network device. Or the first device and the second device are different terminal devices. When the method provided by the present application is applied to a self-transmitting and self-receiving sensing scenario, the first device is the same as the second device. For example, it can be the same terminal device.

[0160] Specifically, the method includes the following multiple steps.

[0161] S501, the first device sends N groups of signals to the second device.

[0162] Specifically, the first device sends N groups of signals to the second device. Correspondingly, the second device receives N groups of signals. The N groups of signals are respectively located in N time windows, and each group of signals in the N groups of signals includes M signals. The Mth signal in the ith group of signals and the first signal in the (i + 1)th group of signals occupy the same frequency domain resources. The M signals in the ith group of signals are located on M resources, and the time domain resources of these M resources are different. The frequency domain resource of any one of these M resources is one of L frequency domain resources, and two adjacent frequency domain resources in these L frequency domain resources partially overlap. The N groups of signals include the ith group of signals and the (i + 1)th group of signals, that is, the ith group of signals and the (i + 1)th group of signals belong to two adjacent groups of signals among the N groups of signals. Wherein, i is any integer greater than or equal to 1 and less than or equal to N - 1. For example, i can be equal to 1, 2, 3, etc. N or M or M is any integer greater than or equal to 2. For example, N can be equal to 2, 3, 4, 5, etc. M or M can be equal to 2, 3, 4, 5, etc. L is any integer greater than or equal to 2 and less than or equal to M. For example, L can be equal to 2, 3... M. i The M i resources are located on M i resources, and the time domain resources of these M i resources are different. The frequency domain resource of any one of these M i resources is one of L i frequency domain resources, and two adjacent frequency domain resources in these L i frequency domain resources partially overlap. N groups of signals include the ith group of signals and the (i + 1)th group of signals, that is, the ith group of signals and the (i + 1)th group of signals belong to two adjacent groups of signals among the N groups of signals. Wherein, i is any integer greater than or equal to 1 and less than or equal to N - 1. For example, i can be equal to 1, 2, 3, etc. N or M or M i is any integer greater than or equal to 2. For example, N can be equal to 2, 3, 4, 5, etc. M or M i can be equal to 2, 3, 4, 5, etc. L i is any integer greater than or equal to 2 and less than or equal to M i For example, L i .

[0163] It can be understood that the ith group of signals and the (i + 1)th group of signals are two adjacent groups of signals. Similarly, the M i+1 signals in the (i + 1)th group of signals are located on M i+1 resources, and the time domain resources of these M i+1 resources are different. The frequency domain resource of any one of these M i+1 resources is one of L i+1 frequency domain resources, and two adjacent frequency domain resources in these L i+1 frequency domain resources partially overlap. Wherein, L i+1 is any integer greater than or equal to 2 and less than or equal to M i+1 For example, L i+1 can be equal to 2, 3... M i .

[0164] It should be noted that in the description of this application, the subscript of the letter is used to represent one of the corresponding N groups of signals. For example, M i resources refer to the M resources of the ith group of signals, and M i+1 resources refer to the M resources of the (i + 1)th group of signals. Another example is L iA frequency domain resource refers to L resources of the i-th group of signals, where L i+1 A frequency domain resource refers to L resources of the (i + 1)-th group of signals.

[0165] It should also be noted that among the N groups of signals sent by the first device, since the frequency domain resources of the last resource in the previous time window and the first resource in the subsequent time window in adjacent time windows are the same, the first device can avoid frequency hopping when sending the last signal in the previous time window and the first signal in the subsequent time window, thereby avoiding additional random phase errors introduced by frequency hopping between adjacent time windows (specifically, reference can be made to the exemplary description in the following Figures 7 to 14 ). At the same time, in each time window, any two adjacent frequency domain resources among multiple frequency domain resources partially overlap, which is convenient for estimating the random phase error introduced by frequency hopping within each time window. Exemplarily,

[0166] such as Figure 6 In a time window shown, in the order of time domain, the first device sequentially sends signals on frequency domain resources #1, #2, #3, #4, and #3. Among them, frequency domain resource #1 and frequency domain resource #2 are adjacent frequency domain resources, frequency domain resource #1 and frequency domain resource #5 are adjacent frequency domain resources, frequency domain resource #3 and frequency domain resource #4 are adjacent frequency domain resources, and frequency domain resource #4 and frequency domain resource #5 are adjacent frequency domain resources. Among them, the random phase error between frequency domain resource #1 and frequency domain resource #2 can be estimated and compensated through the overlapping area between frequency domain resource #1 and frequency domain resource #2. The random phase error between frequency domain resource #3 and frequency domain resource #4 can be compensated through the overlapping area between frequency domain resource #3 and frequency domain resource #4. The random phase error between frequency domain resource #4 and frequency domain resource #5 can be compensated through the overlapping area between frequency domain resource #4 and frequency domain resource #5. When the phase differences between the above-mentioned various frequency domain resources are compensated, the random phase error between frequency domain resource #2 and frequency domain resource #3 can be further indirectly compensated through the overlapping area between frequency domain resource #1 and frequency domain resource #5, so that all random phase errors within this time window can be compensated. It can be understood that the above process of compensating the random phase error introduced by frequency hopping within a time window is only an exemplary description, and the present application does not limit the specific processing method.

[0167] Optionally, the time lengths occupied by the N time windows are the same. In the description of the embodiments of the present application, it is exemplified that the time lengths occupied by the N time windows are the same. Exemplarily, in the following Figures 7 to 14 8 different groups of N groups of signals are respectively shown. At the same time, it can be understood that in Figures 7 to 14Among them, every N groups of signals are not completely shown, only some groups are shown. For example, in Figure 8 only 6 groups out of N groups are shown. In Figure 9 only 5 groups out of N groups are shown, and so on.

[0168] The time length occupied by each time window can refer to the time interval between the start time of the previous time window and the start time of the next time window, or can refer to the time interval between the end time of the previous time window and the end time of the next time window, or can also refer to the time interval between the middle time of the previous time window and the middle time of the next time window. This application does not make a limitation on this.

[0169] The N time windows can also be understood as N periods, and the time length occupied by each time window can also be understood as the period duration.

[0170] Optionally, that the Mth signal in the ith group of signals and the 1st signal in the (i + 1)th group of signals occupy the same frequency domain resource can mean that the Mth signal in the ith group of signals and the 1st signal in the (i + 1)th group of signals are located in the same frequency range. For example, the Mth signal in the ith group of signals and the 1st signal in the (i + 1)th group of signals can respectively occupy different teeth of the same resource block set.

[0171] Optionally, before the first device sends N groups of signals to the second device, method 500 further includes S502.

[0172] S502, the first device determines N groups of signals and / or M signals.

[0173] Specifically, when each group of signals in the N groups of signals includes M signals, the first device can only determine M signals, or determine N groups of signals. It can be understood that in some embodiments, it can also be that the first device determines multiple groups of signals less than N groups in the N groups of signals. This application does not make a limitation. In some embodiments, for the M i resources of the ith group and the M i+1 resources of the (i + 1)th group, the L i frequency domain resources of the M i resources and the L i+1 frequency domain resources of the M i+1 resources are different. At this time, the frequency ranges included in two adjacent time windows overlap. Exemplarily, as Figure 7 shown, the frequency ranges of the 5 resources in group 1 and the 5 resources in group 2 are different. When the frequency range of the 5 frequency domain resources in group 1 is 0 - 100 MHz, the frequency range of the 5 frequency domain resources in group 2 can be 80 - 180 MHz. In some other embodiments, for the M i resources of the ith group and the M i+1For a resource, M i L of a resource i The number of frequency-domain resources and M i+1 L of a resource i+1 The number of frequency-domain resources is the same. For example, in Figure 7 The frequency ranges of the 5 resources in group 2 and the 5 resources in group 3 are 80 - 180 MHz, and the frequency ranges of the 5 resources in group 4 and the 5 resources in group 5 are 0 - 100 MHz. In other words, this application does not limit the frequency ranges corresponding to each group of M frequency-domain resources in N groups, and they can be the same or different. The frequency ranges in the above examples can be regarded as relative frequency ranges for a certain carrier frequency, not absolute frequency ranges. For the convenience of examples and explanations, in the following specific embodiments and drawings, it is described by taking the N groups of frequency resources as the same as an example.

[0174] In some embodiments, the frequency-domain resources of the m-th resource among the M i resources and the frequency-domain resources of the m-th resource among the M i+1 resources are different. In other embodiments, the frequency-domain resources of the m-th resource among the M i resources and the frequency-domain resources of the m-th resource among the M i+1 resources are the same, where m is any integer greater than or equal to 1 and less than or equal to M. For example, m can be equal to 1, 2... M.

[0175] Next, a detailed description is given respectively for the case where the frequency-domain resources of the m-th resource among the M i resources and the frequency-domain resources of the m-th resource among the M i+1 resources are different, or the case where the frequency-domain resources of the m-th resource among the M i resources and the frequency-domain resources of the m-th resource among the M i+1 resources are the same.

[0176] Specifically, when the frequency-domain resources of the m-th resource among the M i resources and the frequency-domain resources of the m-th resource among the M i+1 resources are different, optionally, the number of frequency resources occupied by M signals is the same as the number of time-domain resources occupied by M signals. The following takes the case where the number of frequency resources occupied by M signals is the same as the number of time-domain resources occupied by M signals as an example for description.

[0177] In some embodiments, the frequency-domain resources of the 1st resource among the M i resources are the frequency-domain resources with the lowest frequency, and the frequency-domain resources of the 1st resource among the M i+1 resources are the frequency-domain resources with the highest frequency. For example, M iThe starting physical resource block (PRB) of the frequency-domain resource of the first resource among M resources corresponds to the lowest frequency position among all frequency-domain resources. i+1 The ending PRB of the frequency-domain resource of the first resource among M resources corresponds to the highest frequency position among all frequency-domain resources. In one implementable manner, M i resources or M i+1 The frequency of the frequency-domain resource of the x-th resource among M resources is lower than the frequency of the frequency-domain resource of the (x + 1)-th resource, where x is any integer greater than or equal to 1 and less than or equal to M - 1. Or, in another implementable manner, M i resources or M i+1 The frequency-domain resource of the y-th resource among M resources is the frequency-domain resource with the highest frequency, and the frequency-domain resource of the (y + 1)-th resource is the frequency-domain resource with the lowest frequency, where y is an integer greater than or equal to 1 and less than or equal to M - 1.

[0178] Exemplarily, for Figure 8 Group 1 and Group 2, the frequency-domain resources of Resource 11 in Group 1 and Resource 21 in Group 2 are different, that is, the frequency-domain resources of the first resource in Group 1 and the first resource in Group 2 are different. The same applies hereinafter and will not be elaborated. The frequency-domain resources of Resource 12 in Group 1 and Resource 22 in Group 2 are different, the frequency-domain resources of Resource 13 in Group 1 and Resource 23 in Group 2 are different, the frequency-domain resources of Resource 14 in Group 1 and Resource 24 in Group 2 are different, and the frequency-domain resources of Resource 15 in Group 1 and Resource 25 in Group 2 are different. At the same time, the frequency-domain resource of Resource 11 in Group 1 is the frequency-domain resource with the lowest frequency, and the frequency-domain resource of Resource 21 in Group 2 is the frequency-domain resource with the highest frequency. For Group 1, the frequency of the frequency-domain resource of the previous resource is lower than the frequency of the frequency-domain resource of the subsequent resource, that is, the frequency of the frequency-domain resource of Resource 11 is lower than the frequency of the frequency-domain resource of Resource 12, the frequency of the frequency-domain resource of Resource 12 is lower than the frequency of the frequency-domain resource of Resource 13, the frequency of the frequency-domain resource of Resource 13 is lower than the frequency of the frequency-domain resource of Resource 14, and the frequency of the frequency-domain resource of Resource 14 is lower than the frequency of the frequency-domain resource of Resource 15. For Group 2, among the 5 resources it contains, there are two adjacent resources. The frequency-domain resource of the previous resource is the frequency-domain resource with the highest frequency, and the frequency-domain resource of the subsequent resource is the frequency-domain resource with the lowest frequency. That is, the frequency-domain resource of Resource 21 is the frequency-domain resource with the highest frequency, and the frequency-domain resource of Resource 22 is the frequency-domain resource with the lowest frequency.

[0179] Exemplarily, for Figure 9For Group 1 and Group 2, the frequency-domain resources of Resource 11 in Group 1 and Resource 21 in Group 2 are different. That is, the frequency-domain resources of the first resource in Group 1 and the first resource in Group 2 are different. The same applies hereinafter and will not be elaborated further. The frequency-domain resources of Resource 12 in Group 1 and Resource 22 in Group 2 are different. The frequency-domain resources of Resource 13 in Group 1 and Resource 23 in Group 2 are different. The frequency-domain resources of Resource 14 in Group 1 and Resource 24 in Group 2 are different. The frequency-domain resources of Resource 15 in Group 1 and Resource 25 in Group 2 are different. At the same time, the frequency-domain resource of Resource 11 in Group 1 is the frequency-domain resource with the lowest frequency, and the frequency-domain resource of Resource 21 in Group 2 is the frequency-domain resource with the highest frequency. For Group 1, the frequency of the frequency-domain resource of its previous resource is lower than the frequency of the frequency-domain resource of its subsequent resource. That is, the frequency of the frequency resource of Resource 11 is lower than the frequency of the frequency resource of Resource 12, the frequency of the frequency resource of Resource 12 is lower than the frequency of the frequency resource of Resource 13, the frequency of the frequency resource of Resource 13 is lower than the frequency of the frequency resource of Resource 14, and the frequency of the frequency resource of Resource 14 is lower than the frequency of the frequency resource of Resource 15. For Group 2, among the five resources it contains, there are two adjacent resources. The frequency-domain resource of the previous resource is the frequency-domain resource with the highest frequency, and the frequency-domain resource of the subsequent resource is the frequency-domain resource with the lowest frequency. That is, the frequency-domain resource of Resource 21 is the frequency-domain resource with the highest frequency, and the frequency-domain resource of Resource 22 is the frequency-domain resource with the lowest frequency.

[0180] Specifically, when M i the frequency-domain resource of the m-th resource among the resources and M i+1 the frequency-domain resource of the m-th resource among the resources are different. Optionally, the number of frequency resources occupied by M signals is the same as the number of time-domain resources occupied by M signals. Hereinafter, an example where the number of frequency resources occupied by M signals is the same as the number of time-domain resources occupied by M signals will be used for illustration.

[0181] In some other embodiments, the frequency of the frequency-domain resource of the first resource among M i resources is higher than the frequency of the frequency-domain resource of the first resource among M i+1 resources. For example, the starting PRB index of the frequency-domain resource of the first resource among M i resources is n prb , and the starting PRB index of the frequency-domain resource of the first resource among M i+1 resources is n prb - Bhop + Boverlap, where Bhop represents the frequency hopping bandwidth, for example, 48 RBs, and Boverlap represents the overlapping bandwidth between two adjacent frequency-domain resources, for example, 1 or 2 or 4 RBs. In one implementable manner, M i resources or M i+1The frequency of the frequency-domain resource of the x-th resource among M resources is lower than the frequency of the frequency-domain resource of the (x + 1)-th resource, where x is any integer greater than or equal to 1 and less than or equal to M - 1. Alternatively, in another implementable manner, M i resources or M i+1 the frequency-domain resource of the y-th resource among the resources is the frequency-domain resource with the highest frequency, and the frequency-domain resource of the (y + 1)-th resource is the frequency-domain resource with the lowest frequency, where y is an integer greater than or equal to 1 and less than or equal to M - 1.

[0182] Exemplarily, for Figure 8 groups 2 and 3 in, the frequency-domain resources of resource 21 in group 2 and resource 31 in group 3 are different, that is, the frequency-domain resources of the first resource in group 2 and the first resource in group 3 are different. The same applies hereinafter and will not be elaborated.

At the same time, the frequency of the frequency-domain resource of resource 21 is higher than the frequency of the frequency-domain resource of resource 31. For group 2, among the 5 resources it contains, there are two adjacent resources. The frequency-domain resource of the previous resource is the frequency-domain resource with the highest frequency, and the frequency-domain resource of the latter resource is the frequency-domain resource with the lowest frequency. That is, the frequency-domain resource of resource 21 is the frequency-domain resource with the highest frequency, and the frequency-domain resource of resource 22 is the frequency-domain resource with the lowest frequency.

That is, the frequency-domain resources of resource 54 are the frequency-domain resources with the highest frequency, and the frequency-domain resources of resource 55 are the frequency-domain resources with the lowest frequency.

[0185] Exemplarily, for Figure 8For groups 5 and 6, the frequency domain resources of resource 51 in group 5 and resource 61 in group 6 are different. That is, the frequency domain resources of the first resource in group 5 and the first resource in group 6 are different. The same applies hereinafter and will not be elaborated further.

[0186] Specifically, when M i the frequency domain resources of the m-th resource among the resources and M i+1 the frequency domain resources of the m-th resource among the resources are different, optionally, the number of frequency resources occupied by M signals is the same as the number of time domain resources occupied by M signals. The following takes the case where the number of frequency resources occupied by M signals is the same as the number of time domain resources occupied by M signals as an example for illustration.

[0187] In some embodiments, M i the frequency domain resources of the first resource among the resources are the frequency domain resources with the highest frequency, and M i+1 the frequency domain resources of the first resource among the resources are the frequency domain resources with the lowest frequency. For example, M i the ending PRB of the frequency domain resources of the first resource among the resources corresponds to the position of the highest frequency among all frequency domain resources, and M i+1 the starting PRB of the frequency domain resources of the first resource among the resources corresponds to the position of the lowest frequency among all frequency domain resources. In one implementable manner, M i the frequency of the frequency domain resources of the x-th resource among the resources or M i+1 is higher than the frequency of the frequency domain resources of the (x + 1)-th resource, where x is any integer greater than or equal to 1 and less than or equal to M - 1. Or, in another implementable manner, the M i the resources or the Mi+1 The frequency domain resource of the y-th resource among the M resources is the frequency domain resource with the lowest frequency, and the frequency domain resource of the (y + 1)-th resource is the frequency domain resource with the highest frequency, where y is an integer greater than or equal to 1 and less than or equal to M - 1.

[0188] Exemplarily, for Figure 10 groups 1 and 2 in, the frequency domain resources of resource 11 in group 1 and resource 21 in group 2 are different, that is, the frequency domain resources of the first resource in group 1 and the first resource in group 2 are different. The same applies hereinafter and will not be elaborated. The frequency domain resources of resource 12 in group 1 and resource 22 in group 2 are different, the frequency domain resources of resource 13 in group 1 and resource 23 in group 2 are different, the frequency domain resources of resource 14 in group 1 and resource 24 in group 2 are different, and the frequency domain resources of resource 15 in group 1 and resource 25 in group 2 are different. At the same time, the frequency domain resource of resource 11 in group 1 is the frequency domain resource with the highest frequency, and the frequency domain resource of resource 21 in group 2 is the frequency domain resource with the lowest frequency. For group 1, the frequency of the frequency domain resource of its previous resource is higher than that of the frequency domain resource of its subsequent resource, that is, the frequency of the frequency resource of resource 11 is higher than the frequency of the frequency resource of resource 12, the frequency of the frequency resource of resource 12 is higher than the frequency of the frequency resource of resource 13, the frequency of the frequency resource of resource 13 is higher than the frequency of the frequency resource of resource 14, and the frequency of the frequency resource of resource 14 is higher than the frequency of the frequency resource of resource 15. For group 2, among the 5 resources it contains, there are two adjacent resources. The frequency domain resource of the previous resource is the frequency domain resource with the lowest frequency, and the frequency domain resource of the subsequent resource is the frequency domain resource with the highest frequency. That is, the frequency domain resource of resource 21 is the frequency domain resource with the lowest frequency, and the frequency domain resource of resource 22 is the frequency domain resource with the highest frequency.

[0189] Specifically, when the frequency domain resource of the m-th resource among the M i resources is different from the frequency domain resource of the m-th resource among the M i+1 resources, optionally, the number of frequency resources occupied by the M signals is the same as the number of time domain resources occupied by the M signals. The following takes the case where the number of frequency resources occupied by the M signals is the same as the number of time domain resources occupied by the M signals as an example for illustration.

[0190] In some embodiments, the frequency of the frequency domain resource of the first resource among the M i resources is lower than the frequency of the frequency domain resource of the first resource among the M i+1 resources. For example, the starting PRB index of the frequency domain resource of the first resource among the M i resources is n prb , and the starting PRB index of the frequency domain resource of the first resource among the M i+1 resources is n prb+Bhop - Boverlap, where Bhop represents the hopping frequency bandwidth, for example, 48 RBs, and Boverlap represents the overlapping bandwidth between two adjacent frequency domain resources, for example, 1 or 2 or 4 RBs. In one implementable way, M i resources or the x-th resource among M i+1 resources has a frequency of the frequency domain resource higher than that of the (x + 1)-th resource, where x is any integer greater than or equal to 1 and less than or equal to M - 1. Or, in another implementable way, the M i resources or the y-th resource among the M i+1 resources has the lowest-frequency frequency domain resource, and the (y + 1)-th resource has the highest-frequency frequency domain resource, where y is an integer greater than or equal to 1 and less than or equal to M - 1.

[0191] Exemplarily, for Figure 9 Group 3 and Group 4, the frequency domain resources of Resource 31 in Group 3 and Resource 41 in Group 4 are different, that is, the frequency domain resources of the first resource in Group 3 and the first resource in Group 4 are different. The same applies hereinafter and will not be elaborated. The frequency domain resources of Resource 32 in Group 3 and Resource 42 in Group 4 are different, the frequency domain resources of Resource 33 in Group 3 and Resource 43 in Group 4 are different, the frequency domain resources of Resource 34 in Group 3 and Resource 44 in Group 4 are different, and the frequency domain resources of Resource 35 in Group 3 and Resource 45 in Group 4 are different. At the same time, the frequency of the frequency domain resource of Resource 31 is lower than that of the frequency domain resource of Resource 41. For Group 3, among the 5 resources it contains, there are two adjacent resources.

[0209] Exemplarily, for Figure 12 groups 2 and 3 in [[]], the frequency-domain resources of resource 21 in group 2 and resource 31 in group 3 are different, that is, the frequency-domain resources of the first resource in group 2 and the first resource in group 3 are different.

[0210] Exemplarily, for Figure 12 Groups 4 and 5, the frequency domain resources of Resource 41 in Group 4 and Resource 51 in Group 5 are different, that is, the frequency domain resources of the first resource in Group 4 and the first resource in Group 5 are different. The same applies hereinafter and will not be elaborated further. The frequency domain resources of Resource 42 in Group 4 and Resource 52 in Group 5 are different, the frequency domain resources of Resource 43 in Group 4 and Resource 53 in Group 5 are different, the frequency domain resources of Resource 44 in Group 4 and Resource 54 in Group 5 are different, and the frequency domain resources of Resource 45 in Group 4 and Resource 55 in Group 5 are different.

[0211] Specifically, when the frequency domain resources of the m-th resource among M i resources are the same as the frequency domain resources of the m-th resource among M i+1 resources, the frequency domain resources of the first resource and the M-th resource among M i resources are the same, and the frequency domain resources of the first resource and the M-th resource among M i+1 resources are the same, where m is any integer greater than or equal to 1 and less than or equal to M. Optionally, the number of frequency resources occupied by M signals is less than the number of time domain resources occupied by M signals. The following takes the case where the number of frequency resources occupied by M signals is less than the number of time domain resources occupied by M signals as an example for illustration.

[0212] In an implementable manner, the frequency domain resources of the first resource and the M-th resource among M i resources or M i+1 resources are the lowest frequency domain resources. At the same time, the frequency domain resource of the (M - 1)-th resource among M i resources or M i+1 resources is the highest frequency domain resource, and the frequency domain resource of the M-th resource is the lowest frequency domain resource.

[0213] Exemplarily, forFigure 13 For each of Group 1 to Group 5 in Figure 13 , the number of frequency-domain resources is less than the number of time-domain resources. At the same time, the frequency-domain resources of Resource 11, Resource 21, Resource 31, Resource 41, and Resource 51 are the same; the frequency-domain resources of Resource 12, Resource 22, Resource 32, Resource 42, and Resource 52 are the same, the frequency-domain resources of Resource 13, Resource 23, Resource 33, Resource 43, and Resource 53 are the same, the frequency-domain resources of Resource 14, Resource 24, Resource 34, Resource 44, and Resource 54 are the same, the frequency-domain resources of Resource 15, Resource 25, Resource 35, Resource 45, and Resource 55 are the same, and the frequency-domain resources of Resource 16, Resource 26, Resource 36, Resource 46, and Resource 56 are the same. For any one of Group 1 to Group 5, the frequency-domain resources of the first resource and the sixth resource among the six resources it contains are the lowest-frequency domain resources. At the same time, the frequency-domain resource of the fifth resource is the highest-frequency domain resource, and the frequency-domain resource of the sixth resource is the lowest-frequency domain resource.

[0214] In another implementable manner, for i the M i+1 resources or the first resource among the M i resources and the M i+1 th resource, their frequency-domain resources are the highest-frequency domain resources. At this time, for the M

[0215] resources or the M Figure 14 th resource, the frequency-domain resource of the (M - 1) Figures 7 to 14 th resource is the lowest-frequency domain resource, and the frequency-domain resource of the M Figures 7 to 14The periodic frequency hopping pattern shown, as long as the frequency domain resources occupied by the Mth signal in the ith group of signals and the first signal in the (i + 1)th group of signals are the same, and periodic frequency hopping is avoided, all fall within the protection scope of this application.

[0216] It should be noted that in the solution of this application, the frequency of the frequency domain resources can refer to the frequency of the highest-frequency subcarrier included in the frequency domain resources, or the frequency of the lowest-frequency subcarrier, or the frequency of the central subcarrier, or the frequency at other agreed positions. This application does not make any limitations in this regard.

[0217] In addition, it should also be noted that the above Figures 7 to 14 is only a schematic drawing. For the sake of convenience of explanation, the time length occupied by each frequency domain resource in each time window has been slightly exaggerated. At the same time, for the clarity of the drawings, the time length between time windows has been reduced, that is, the above drawings are only examples and are not drawn strictly to scale. It should be understood that for multiple frequency hopping resources within each time window, their channel information can be considered to be basically unchanged. For different time windows, the channel changes.

[0218] Figure 15 This is a schematic flowchart of the second communication method 1500 provided by an embodiment of this application. As Figure 15 shown, this schematic flowchart is shown by taking the interaction between a first device and a second device as an example. Among them, the steps executed by the first device and / or the second device can be executed by a module or unit in the first device and / or the second device. For example, it is executed by a chip in the first device and / or the second device.

[0219] Similarly, when the method 1500 is applied to a sensing scenario, the N groups of signals or M signals are sensing signals. The sensing signals can refer to sensing reference signals, or positioning reference signals, or communication signals for sensing, etc. This application does not make any limitations in this regard. At this time, the first device and the second device can be the same. For example, both the first device and the second device are terminal devices. They can also be different. For example, the first device is a terminal device and the second device is a network device. The description of this part can refer to the description in the above Figure 5 and will not be elaborated here. Specifically, this method includes the following multiple steps.

[0220] S1501, the first device sends N groups of signals to the second device.

[0221] Before S1501, the method 1500 further includes S1502, the first device determines N groups of signals and / or M signals.

[0222] Specifically, S1501 and S1502 can respectively refer to S501 and S502 in the above Figure 5 and will not be elaborated here.

[0223] Optionally, before S1502, method 150 may further include S1503, where the first device receives configuration information sent by the third device.

[0224] In an implementable manner, the third device is a network device, such as a base station, and the first device is, for example, a UE. For a sensing scenario (uu interface) involving a base station, the base station may configure the hopping pattern of N groups of reference signals for the UE through the configuration information carried in the signaling. The configuration information may include the number of hops (e.g., the number of time-domain resources), the bandwidth of each hop, the overlapping bandwidth of each hop, the position of the starting PRB of the first hop, the time slot and symbol where the first hop starts, the time slot offset and symbol of each hop compared to the first hop, the number of continuously occupied symbols, etc., and may also give the lowest frequency or the highest frequency. In addition, the configuration information further includes the length of each of the N time windows, and the hopping pattern on each time window.

[0225] Optionally, all time windows may be configured with a default hopping pattern, such as using Figures 7 to 14 any one of the hopping patterns. After the hopping pattern of the first time window is configured, the hopping parameters of subsequent time windows may be determined according to the hopping parameters of the first time window. For example, parameters such as the bandwidth of each hop, the overlapping bandwidth of each hop, the time slot offset and symbol of each hop compared to the first hop, and the number of continuously occupied symbols may directly reuse the parameters of the first cycle. It can be understood that all time windows using the default hopping pattern does not mean that the hopping patterns of all time windows are the same. For example, Figures 7 to 12 in the hopping pattern shown, the hopping patterns used by different time windows may be different.

[0226] In another implementable manner, for the SL sensing scenario (PC5 interface), such as UE self-transmitting and self-receiving, UE self-transmitting and other-receiving, etc. In this scenario, the UE may adopt an autonomously selected resource allocation method (e.g., mode2, which can refer to the relevant descriptions in the current technology and will not be elaborated here). Before sending a signal, the UE listens for resource reservation information sent by other UEs and measures the corresponding received power, and selects resources that are not reserved by other UEs or are reserved by other UEs but have a lower received power, so as to avoid interference between UEs due to occupying the same transmission resources in advance.

[0227] To avoid interference caused by devices to each other, optionally, method 1500 further includes S1504.

[0228] S1504, the first device sends multiple pieces of information, and each piece of information in the multiple pieces of information indicates multiple resource reservation periods.

[0229] Specifically, the resource reservation period is defined as the time interval between two resources corresponding to the same frequency-domain resource on two adjacent time windows. That is, the time-domain resource of the j-th resource among the M resources in the i-th group, and the time-domain resource of the p-th resource among the M resources in the (i + 1)-th group, where the frequency-domain resource of the j-th resource is the same as the frequency-domain resource of the p-th resource, and j and p are any integers greater than or equal to 1 and less than or equal to M. i The M i+1 resources in the i-th group, and the time interval between the time-domain resources of the p-th resource among the M resources in the (i + 1)-th group, where the frequency-domain resource of the j-th resource is the same as the frequency-domain resource of the p-th resource, and j and p are any integers greater than or equal to 1 and less than or equal to M.

[0230] Optionally, multiple resource reservation periods can be carried in the sidelink control information (SCI), for example, carried in the resource reservation period field in the SCI. It should be noted that the time interval between two resources corresponding to the same frequency-domain resource between any two adjacent time windows can be the same or different. When the time interval between two resources corresponding to the same frequency-domain resource is the same, the resource reservation period field carries one resource reservation period, and when it is different, the resource reservation period field carries multiple resource reservation periods.

[0231] In some embodiments, the time interval between the time-domain resource of the j-th resource among the M resources and the time-domain resource of the p-th resource among the M resources can be T + T i or T - (M - 1)T i+1 . Wherein, the frequency-domain resource of the j-th resource is the same as the frequency-domain resource of the p-th resource, where j and p are any integers greater than or equal to 1 and less than or equal to M, and T s is the time interval between two adjacent time-domain resources among the M resources or among the M resources, and T is the interval between the start transmission time of the M s signals and the start transmission time of the M s signals. It can be understood that T can also be the interval between the end transmission time of the M i signals and the end transmission time of the M i+1 signals, etc. T can also be understood as the length of each time window, or the cycle duration, which is not limited in this application. i signals and the start transmission time of the M i+1 signals. It can be understood that T can also be the interval between the end transmission time of the M i signals and the end transmission time of the M i+1 signals, etc. T can also be understood as the length of each time window, or the cycle duration, which is not limited in this application.

[0232] Exemplarily, in Figure 8 groups 1, 2, and 3, resources 14, 25, and 31 are resources with the same frequency-domain resource. For resources 14 and 25, the resource reservation period they represent is T + T s , and for resources 25 and 31, the resource reservation period they represent is T - 4T s .

[0233] In some other embodiments, M i The time domain resource of the jth resource among the resources, and M i+1 The time interval between the time domain resources of the pth resource among the resources is T+(M - 1 - 2q)T s Or T-(M - 1 - 2q)T s . The frequency domain resources of the jth resource and the pth resource are the same, where j and p are any integers greater than or equal to 1 and less than or equal to M, and T s Is M i Among the resources or M i+1 The time interval between two adjacent time domain resources among the resources, q is an integer greater than or equal to 0 and less than M i Among the resources or M i+1 The number of frequency domain resources among the resources, the value of q is related to the frequency domain resource of the jth resource of M i Among the resources or the frequency domain resource of the pth resource of M i+1 Among the resources, and T is the interval between the start transmission times of M i Signals and M i+1 The start transmission times of the signals. It can be understood that T can also be the interval between the end transmission times of M i Signals and M i+1 The end transmission times of the signals, etc. T can also be understood as the length of each time window, or the cycle duration, which is not limited in this application.

[0234] Exemplarily, in Figure 11 Groups 1, 2, and 3, resources 11, 25, and 31 are resources with the same frequency domain resources. For resources 11 and 25, since the frequency domain resources of resources 11, 25, and 31 are all the first frequency domain resources among all frequency domain resources (taking the frequency resources sorted from high to low as an example), so q is equal to 0 (similarly, for the second frequency domain resource among all frequency domain resources, q is equal to 1, etc., which will not be elaborated here), and the resource reservation period it represents is T+(5 - 1 - 2*0)T s , that is, T + 4T s , for resources 25 and 31, the resource reservation period they represent is T - 4T s .

[0235] In some other embodiments, M i The time domain resource of the jth resource among the resources, and M i+1 The time interval between the time domain resources of the pth resource among the resources is T. Among them, T is M i The start transmission times of the signals and M i+1The interval between the start transmission times of the signals. It can be understood that T can also be M i The end transmission time of the signals and M i+1 The interval between the end transmission times of the signals. Alternatively, T is the time domain resource of the jth resource among the M i resources, and the time interval between the time domain resources of the jth resource among the M i+1 resources, where j is any integer greater than or equal to 1 and less than or equal to M. T can also be understood as the length of each time window, or the cycle duration, which is not limited in this application.

[0236] Exemplarily, in Figure 13 Groups 1, 2, and 3, resources 11, 21, and 31 are resources with the same frequency domain resources. For resources 11 and 21, the resource reservation period they represent is T. For resources 21 and 31, the resource reservation period they represent is still T.

[0237] Optionally, the first device can send multiple pieces of information on each time window. Optionally, the first device can send M pieces of information on each time window, and each piece of information among the M pieces of information indicates the resource reservation period of each signal among the M signals.
