Communication method and device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on January 3, 2024, with application number 202410014966.4, and priority to the Chinese patent application entitled “A Communication Method and Device”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and more particularly, to a communication method and apparatus. Background Art

[0003] With the development of fifth-generation (5G) IoT services (such as wearables, industrial sensors, and video surveillance), research on reduced capability (RedCap) devices is gaining increasing attention. 5G RedCap devices offer advantages such as reduced terminal complexity. They effectively balance 5G's broad bandwidth, high speed, wide connectivity, and low latency in terms of bandwidth, power consumption, antenna design, and cost, meeting the networking needs of diverse industries and supporting the expanding IoT market.

[0004] However, precisely because of this simplified functionality, the bandwidth capacity of RedCap devices has been reduced from the 100MHz of standard 5G terminals to 20MHz. Currently, to achieve high ranging resolution for RedCap devices, frequency hopping is typically used to transmit reference signals for ranging. However, when the reference signal needs to be transmitted across multiple time windows, random phase errors are introduced between adjacent time windows, resulting in performance degradation. Therefore, how to avoid the phase errors introduced by frequency hopping and improve system performance is a critical issue that needs to be addressed. Summary of the Invention

[0005] The present application provides a communication method and apparatus that can avoid random phase errors introduced by frequency hopping between adjacent time windows and improve system performance.

[0006] In the 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 does not limit this. For the sake of convenience of description, the following is an example 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 iOn the resources, the M i The time domain resources of the resources are different, and the M i The frequency domain resource of any one of the resources is L i One of the frequency domain resources, the L i Two adjacent frequency domain resources in the frequency domain resources partially overlap, wherein the i-th group signal and the i+1-th group signal belong to the N-group signal, i is any integer greater than or equal to 1 and less than or equal to N-1, 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 Any integer.

[0007] 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 moment of the previous time window and the middle moment of the next time window. This application does not limit this.

[0008] It should be noted that the signal is located in the time window or the signal is sent within the time window, and the signal may be located in a partial time period within the time window or the signal is sent in a partial time period within the time window. The signal can be concentrated in a certain period of time within the time window, such as the first few time domain resources, which is not limited in this application. The solution of this application 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 periodically sent. The frequency hopping signal is periodically sent in units of cycle duration, so there can be multiple time windows in the time domain, and the time length corresponding to each time window can be understood as the cycle duration. In this application, one of the above-mentioned multiple time windows can be referred to as a cycle, and therefore, N time windows can be understood as N cycles. Based on the above scheme, by setting the frequency domain resources of the last resource of the previous time window and the frequency domain resources of the first resource of the next time window in adjacent time windows to be the same, the sending device does not need to frequency hop when sending the last signal of the previous time window and the first signal of the next time window, thereby avoiding the additional random phase error 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 in each time window.

[0130] The technical solution in this application will be described below with reference to the accompanying drawings.

[0131] FIG1 is a schematic diagram of a communication system 10 applicable to an embodiment of the present application. As shown in FIG1 , the communication system of an embodiment of the present application may include a network device 100 and at least one terminal device (such as 101-105 in FIG1 ). The network device may include one antenna or multiple antennas. In addition, the network device may additionally include a transmitter chain and a receiver chain. Those skilled in the art will understand that they may include multiple components related to signal transmission and reception (such as processors, modulators, multiplexers, demodulators, demultiplexers, or antennas, etc.). FIG1 is only a simplified schematic diagram for example. In addition, the communication system may also include other communication devices, which are not shown in FIG1 .

[0132] The above-mentioned communication system architecture 10 applied to the embodiment of the present application is only an example. The communication system architecture applicable to the embodiment of the present application is not limited to this. For example, any communication system architecture that can realize the functions of the above-mentioned devices can be applicable to the embodiment of the present application.

[0133] Figure 2 is a structural diagram of a communication system 20 applicable to an embodiment of the present application. In the wireless communication system shown in Figure 2, terminal devices can communicate directly with each other without the help of network devices. The interface between terminal devices is called a 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 data can be transmitted directly between terminal devices through SL without going through the network, which can effectively reduce communication delays.

[0134] The solution of the present application can be applied to a communication perception integration scenario or a perception scenario or a positioning scenario, for example, the communication perception integration scenario (or perception scenario or positioning scenario) in which the terminal device sends and the network device receives the self-transmitted and other-received signal in Figure 1, or the communication perception integration scenario (or perception scenario or positioning scenario) in which multiple terminal devices transmit and other-received signal in Figure 2, or the communication perception scenario in which a single terminal device transmits and receives the signal. The signal used for perception can be a specific reference signal, or perception can be performed using a communication signal, which is not limited in this application.

[0135] The technical solutions provided in this application can be applied to various communication systems, such as fifth generation (5G) or new radio (NR) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, etc. The technical solutions provided in this application can also be applied to future communication systems.

[0136] The technical solution provided in 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.

[0137] As an example, V2X communication may include: vehicle-to-vehicle (V2V) communication, vehicle-to-roadside 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 vehicles and people (including pedestrians, cyclists, drivers, or passengers, etc.). V2I refers to communication between vehicles and infrastructure, such as road side units (RSU) or network equipment. Among them, RSU includes two types: terminal-type RSU, which is in a non-mobile state because it is located on the roadside and does not need to consider mobility; base station-type RSU, which can provide timing synchronization and resource scheduling to vehicles communicating with it. V2N refers to communication between vehicles and network equipment. It can be understood that the above is an exemplary description and the embodiments of the present application are not limiting. For example, V2X can also include the current 3GPP Rel-16 and subsequent versions of V2X communications based on the NR system.

[0138] As an example, D2D communication can involve communication between a programmable logic controller (PLC) and its subordinate devices, such as between a PLC and sensors, or between a PLC and actuators. Sensors can be, for example, pressure sensors or temperature sensors. Actuators can be, for example, valve islands or heaters. For example, the PLC receives data measured by all sensors within each cycle and sends execution instructions to the actuators within each cycle.

[0139] The terminal device in the embodiments of the present application may also be referred to as user equipment (UE), access terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device.

The terminal equipment in the network (PLMN), etc., is not limited to this in the embodiments of the present application.

[0140] As an example and not a limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be called wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0141] In the embodiments of the present application, the device for implementing the function of the terminal device can be the terminal device, or a device capable of supporting the terminal device to implement the function, such as a chip system or chip, which can be installed in the terminal device. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices.

[0142] The network device in the embodiments of the present application may be a device for communicating with a terminal device, and may also be referred to as an access network device or a radio access network device. For example, the network device may be a base station. The network device in the embodiments of the present application may refer to a radio access network (RAN) node (or device) that connects a terminal device to a wireless network. A base station may broadly cover various names as follows, or replace the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master station, secondary station, multi-standard radio (motor slide retainer, MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station may be a macro base station, a micro base station, a relay node, a donor node, or the like, or a combination thereof.

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

The base station may also be a mobile switching center and a device that performs base station functions in D2D, V2X, and M2M communications, a network-side device in a future communication network, or a device that performs base station functions in a future communication system. The base station may support networks with the same or different access technologies. The embodiments of this application do not limit the specific technologies and specific device forms adopted by the network equipment.

[0143] Base stations can be fixed or mobile.

The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0146] To facilitate understanding of the embodiments of the present application, a brief description of the terms or technologies involved in the present application is first given.

[0147] 1. Time domain resources and frequency domain resources

[0148] Network devices and terminal devices can sense each other through time-frequency resources. In the embodiments of the present application, time domain resources include, for example, subframes, frames, half subframes or half frames, slots, sub-slots, mini-slots, partial slots, orthogonal frequency division multiplexing (OFDM) symbols, or single carrier frequency division multiple access (SC-FDMA) symbols, etc.

[0149] Frequency domain resources can also be replaced by frequency resources, which means the resources used to carry frequency domain data. Frequency domain resources can be a resource element (RE), a resource block (RB), a sub-channel, a resource pool, a resource block set (RB set), a bandwidth, a bandwidth part (BWP), a carrier, a channel, an interlace RB, an interlace RE, or a comb tooth, etc.

[0150] Figure 3 is a schematic diagram of a time-frequency resource applicable to an embodiment of the present application. Taking the time domain resource as a time slot and the frequency domain resource as an RB as an example, a time slot can include 14 time domain symbols, and an RB can include 12 subcarriers. An RE can be regarded as the minimum resource unit for data transmission, or an RE is the minimum resource unit for resource mapping of data to be transmitted. As shown in Figure 3, an RE corresponds to a symbol in the time domain, such as an OFDM symbol, or a discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) symbol. An RE corresponds to a subcarrier in the frequency domain, and an RE can be used to map a complex symbol, such as a complex symbol obtained by modulation, or a complex symbol obtained by precoding, and this application does not limit this. It should be understood that Figure 3 is only a schematic diagram of a possible time-frequency resource given for ease of understanding, and this application does not limit the specific form of the time-frequency resource.

[0151] 2. Frequency hopping (FH)

[0152] In the perception scenario, the device sends perception signals with different center frequencies but continuous spectra in several time domain resources.

[0153] 3. Frequency hopping pattern

[0154] The set of time-frequency resources corresponding to different moments can be called a frequency hopping pattern. In a frequency hopping pattern, different time-domain resources may correspond to different frequency-domain resources. A frequency hopping pattern can also be called a frequency hopping pattern.

[0155] The above briefly explains the terms involved in this application, which will not be repeated in the following embodiments. In addition, the above explanation of the terms is only for the purpose of facilitating understanding and does not limit the scope of protection of the embodiments of this application.

[0156] In sensing scenarios, the distance and speed of a target can be measured by periodically transmitting reference signals within a certain bandwidth. For example, to achieve a ranging resolution of 0.3m, the sensing signal bandwidth must be at least 500MHz, which places high demands on the UE's analog-to-digital converter (ADC) sampling rate (i.e., to maintain ranging accuracy, the UE's ADC sampling rate must also be at least 500MHz). For RedCap devices, achieving high ranging resolution is difficult due to the limited bandwidth of the signal they can transmit. Therefore, to reduce the requirements for the UE's ADC sampling rate while supporting RedCap devices in achieving high ranging resolution, current solutions use a frequency hopping approach to transmit reference signals for ranging, as shown in Figure 4. In this frequency hopping approach, since the signal bandwidth within a single symbol is small, this approach places lower requirements on the UE's ADC sampling rate and is also compatible with the signal transmission capabilities of RedCap devices. Furthermore, in this frequency hopping approach, since the signal spectra across multiple time-domain resources are continuous and the channels within the multiple time-frequency resources used to complete a frequency hopping pattern can be considered essentially unchanged, these signals can be jointly processed to form an equivalent large-bandwidth signal for ranging.

[0157] However, for each frequency hop in a frequency-hopping pattern, frequency-sensitive components such as phase-locked loops (PLLs), low-noise amplifiers (LNAs), and power amplifiers (PAs) introduce a random phase error between adjacent frequency domain resources. This random error can degrade ranging performance. When periodic frequency hopping is required to transmit a reference signal (i.e., when the frequency-hopping pattern periodicity occurs as shown in Figure 4), random phase errors can also be introduced between adjacent cycles within multiple frequency-hopping cycles, degrading speed measurement performance.

[0158] In view of this, the present application provides a communication method and apparatus that can avoid random phase errors introduced by frequency hopping between adjacent cycles in multiple frequency hopping cycles. When applied in perception scenarios, the performance of the perception system can be improved.

[0159] Figure 5 is a schematic flow chart of a first communication method 500 provided in an embodiment of the present application. As shown in Figure 5, the schematic flow chart is illustrated using the interaction between a first device and a second device as an example, wherein the steps performed by the first device and / or the second device may be performed by a module or unit in the first device and / or the second device, for example, by a chip in the first device and / or the second device.

[0160] It should be noted that when the method provided in the present application is applied to a perception scenario, N groups of signals or M signals are perception signals, such as those used for ranging, positioning, or speed measurement, and the perception signal may refer to a perception reference signal, or a positioning reference signal, or a communication signal used for perception, etc. This application does not limit this. It is understandable that when the method provided in the present application is applied to a perception scenario of self-transmission and self-reception, the first device is different from the second device, for example, the first device may be a terminal device, and the second device may be a network device. Or the first device and the second device are different terminal devices. When the method provided in the present application is applied to a perception scenario of self-transmission and self-reception, the first device is the same as the second device, for example, it may be the same terminal device.

[0161] Specifically, the method includes the following steps.

[0162] S501: A first device sends N groups of signals to a second device.

[0163] Specifically, the first device sends N groups of signals to the second device, and 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 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 Mi On the resource, 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 i Two adjacent frequency domain resources in the N frequency domain resources partially overlap. The N group of signals includes the i-th group signal and the i+1-th group signal, that is, the i-th group signal and the i+1-th group signal belong to two adjacent groups of signals in the N group signal. 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 It can be equal to 2, 3, 4, 5, etc., L i is greater than or equal to 2 and less than or equal to M i Any integer, such as L i Can be equal to 2, 3...M i .

[0164] It can be understood that the i-th group of signals and the i+1-th group of signals are two adjacent groups of signals. Similarly, the M i+1 The signal is located at M i+1 On the resource, the M i+1 The time domain resources of the resources are different. i+1 The frequency domain resource of any one of the resources is L i+1 One of the frequency domain resources, L i+1 Two adjacent frequency domain resources in the frequency domain resources partially overlap, where L i+1 is greater than or equal to 2 and less than or equal to M i+1 Any integer, such as L i+1 Can be equal to 2, 3...M i .

[0165] It should be noted that, in the description of this application, the subscript of a letter is used to represent one of the corresponding N groups of signals. i The resources refer to the M resources of the i-th group of signals, M i+1 The resources refer to the M resources of the i+1th group of signals. For example, L i Frequency domain resources refer to L resources of the i-th group of signals, L i+1 The frequency domain resources refer to the L resources of the (i+1)th group of signals.

[0166] It should also be noted that, among the N groups of signals sent by the first device, since the frequency domain resource of the last resource of the previous time window in adjacent time windows is the same as the frequency domain resource of the first resource of the next time window, the first device does not need to perform frequency hopping when sending the last signal of the previous time window and the first signal of the next time window, thereby avoiding the introduction of additional random phase errors due to frequency hopping between adjacent time windows (specifically, please refer to the exemplary illustrations in Figures 7 to 14 below). At the same time, in each time window, any two adjacent frequency domain resources in multiple frequency domain resources partially overlap, which can facilitate the estimation of the random phase error introduced by frequency hopping in each time window. For example,

[0167] In a time window as shown in Figure 6, the first device sends signals in frequency domain resources #1, #2, #3, #4 and #3 in sequence in the time domain. 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 The random phase error between frequency domain resource #3 and frequency domain resource #4 can be estimated and compensated by the overlapping area between frequency domain resource #1 and frequency domain resource #2. The random phase error between frequency domain resource #4 and frequency domain resource #5 can be compensated by the overlapping area between frequency domain resource #3 and frequency domain resource #4. The phase difference between frequency domain resource #2 and frequency domain resource #3 can be compensated by the overlapping area between frequency domain resource #4 and frequency domain resource #5. Indirect compensation can be further performed through the overlapping region between frequency domain resource #1 and frequency domain resource #5, thereby compensating for all random phase errors within the time window. It will be appreciated that the above process of compensating for random phase errors introduced by frequency hopping within a time window is merely an example, and this application does not limit the specific processing method.

[0168] Optionally, the N time windows occupy the same length of time. In the description of the embodiments of the present application, the N time windows occupy the same length of time as an example. For example, in the following Figures 7 to 14, 8 different groups of N groups of signals are shown. It is also understandable that in Figures 7 to 14, each N group of signals is not fully shown, and only a portion of the groups is shown. For example, in Figures 8, only 6 of the N groups are shown, and in Figure 9, only 5 of the N groups are shown, etc.

[0169] The time length occupied by each time window may refer to the time interval between the start moment of the previous time window and the start moment of the next time window, or the time interval between the end moment of the previous time window and the end moment of the next time window, or the time interval between the middle moment of the previous time window and the middle moment of the next time window. This application does not limit this.

[0170] The N time windows can also be understood as N cycles, and the length of time each time window occupies can also be understood as the cycle length.

[0171] Optionally, the frequency domain resources occupied by the Mth signal in the i-th group of signals and the 1st signal in the i+1-th group of signals are the same, which may mean that the Mth signal in the i-th 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 i-th 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.

[0172] Optionally, before the first device sends N groups of signals to the second device, the method 500 further includes S502.

[0173] S502: The first device determines N groups of signals and / or M signals.

[0174] Specifically, when each group of N signals includes M signals, the first device may determine only M signals, or determine N groups of signals. It is understood that in some embodiments, the first device may determine multiple groups of signals smaller than N groups in the N groups of signals, which is not limited in this application. In some embodiments, for the M signals of the i-th group, i resources and M of the i+1th group i+1 For each resource, M i L of resources i frequency domain resources and M i+1 L of resources i+1 The frequency domain resources of the 5 frequency domain resources in group 1 are different. In this case, the frequency ranges of the two adjacent time windows overlap. For example, as shown in FIG7 , 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 may be 80-180 MHz. In other embodiments, for the M of group i, i resources and M of the i+1th group i+1 For each resource, M i L of resources i frequency domain resources and M i+1 L of resources i+1The frequency domain resources are the same. For example, in Figure 7, the frequency range of the 5 resources in group 2 and the 5 resources in group 3 is 80-180MHz, and the frequency range of the 5 resources in group 4 and the 5 resources in group 5 is 0-100MHz. In other words, the present application does not limit the frequency range corresponding to each group of M frequency domain resources in N groups. They can be the same or different. The frequency range of the above example can be regarded as a relative frequency range for a certain carrier frequency, not an absolute frequency range. For the convenience of example and explanation, the following specific embodiments and drawings are all explained by taking the example of N groups of identical frequency resources as an example.

[0175] In some embodiments, M i The frequency domain resource of the mth resource in the resources and M i+1 The frequency domain resources of the m-th resource in the resources are different. i The frequency domain resource of the mth resource in the resources and M i+1 The frequency domain resources of the m-th resource in the 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.

[0176] Next, for M i The frequency domain resource of the mth resource in the resources and M i+1 The frequency domain resources of the mth resource in the resources are different, or M i The frequency domain resource of the mth resource in the resources and M i+1 The frequency domain resources of the mth resource in the resources are the same and are described in detail respectively.

[0177] Specifically, when M i The frequency domain resource of the mth resource in the resources and M i+1 When the frequency domain resources of the mth resource in the resources are different, 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 is an example in which 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.

[0178] In some embodiments, M i The frequency domain resource of the first resource among the resources is the frequency domain resource with the lowest frequency. i+1 The frequency domain resource of the first resource among the resources is the frequency domain resource with the highest frequency. i The starting physical resource block (PRB) of the frequency domain resource of the first resource in the resources corresponds to the lowest frequency position in all frequency domain resources. i+1The end PRB of the frequency domain resource of the first resource in the resources corresponds to the position of the highest frequency in all frequency domain resources. i Resources or M i+1 The frequency of the frequency domain resource of the xth resource among the resources is lower than the frequency of the frequency domain resource of the x+1th resource, where x is any integer greater than or equal to 1 and less than or equal to M-1. Or, in another achievable manner, M i Resources or M i+1 The frequency domain resource of the yth resource among the resources is the frequency domain resource with the highest frequency, and the frequency domain resource of the y+1th 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.

[0179] For example, for Group 1 and Group 2 in Figure 8 , 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 is true below and will not be repeated. 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 domain resource of the preceding resource has a lower frequency than the frequency domain resource of the succeeding resource. That is, the frequency of resource 11 is lower than the frequency of resource 12, which is lower than the frequency of resource 13, which is lower than the frequency of resource 14, which is lower than the frequency of resource 15. For Group 2, among the five resources it contains, there are two adjacent resources. The frequency domain resource of the preceding resource has the highest frequency, and the frequency domain resource of the succeeding resource has the lowest frequency. That is, the frequency domain resource of resource 21 has the highest frequency, and the frequency domain resource of resource 22 has the lowest frequency.

[0180] For example, for Group 1 and Group 2 in Figure 9, 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 is true below and will not be repeated. 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 domain resource of the preceding resource has a lower frequency than the frequency domain resource of the succeeding resource. That is, the frequency of resource 11 is lower than the frequency of resource 12, which is lower than the frequency of resource 13, which is lower than the frequency of resource 14, which is lower than the frequency of resource 15. For Group 2, among the five resources it contains, there are two adjacent resources. The frequency domain resource of the preceding resource has the highest frequency, and the frequency domain resource of the succeeding resource has the lowest frequency. That is, the frequency domain resource of resource 21 has the highest frequency, and the frequency domain resource of resource 22 has the lowest frequency.

[0181] Specifically, when M i The frequency domain resource of the mth resource in the resources and M i+1 When the frequency domain resources of the mth resource in the resources are different, 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 is an example in which 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.

[0182] In other embodiments, M i The frequency domain resource of the first resource among the resources is higher than M i+1 The frequency of the first resource in the frequency domain of the resources. For example, M i The starting PRB index of the frequency domain resource of the first resource in the resources is n prb , M i+1 The starting PRB index of the frequency domain resource of the first resource in the 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, 2, or 4 RBs. In one achievable method, M i Resources or M i+1The frequency of the frequency domain resource of the xth resource among the resources is lower than the frequency of the frequency domain resource of the x+1th resource, where x is any integer greater than or equal to 1 and less than or equal to M-1. Or, in another achievable manner, M i Resources or M i+1 The frequency domain resource of the yth resource among the resources is the frequency domain resource with the highest frequency, and the frequency domain resource of the y+1th 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.

[0183] For example, for Groups 2 and 3 in Figure 8 , resource 21 in Group 2 and resource 31 in Group 3 have different frequency domain resources. 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 and will not be repeated here. Resource 22 in Group 2 and resource 32 in Group 3 have different frequency domain resources. Resource 23 in Group 2 and resource 33 in Group 3 have different frequency domain resources. Resource 24 in Group 2 and resource 34 in Group 3 have different frequency domain resources. Resource 25 in Group 2 and resource 35 in Group 3 have different frequency domain resources. Furthermore, the frequency domain resource of resource 21 is higher than the frequency domain resource of resource 31. For Group 2, among the five resources it contains, there are two adjacent resources. The frequency domain resource of the first resource has the highest frequency, and the frequency domain resource of the second resource has the lowest frequency. That is, the frequency domain resource of resource 21 has the highest frequency, and the frequency domain resource of resource 22 has the lowest frequency. For group 3, among the five resources it contains, there are two adjacent resources. The first frequency domain resource is the frequency domain resource with the highest frequency, and the second frequency domain resource is the frequency domain resource with the lowest frequency. That is, the frequency domain resource of resource 32 is the frequency domain resource with the highest frequency, and the frequency domain resource of resource 33 is the frequency domain resource with the lowest frequency.

[0184] For example, for Groups 3 and 4 in Figure 8 , resource 31 in Group 3 and resource 41 in Group 4 have different frequency domain resources. That is, the first resource in Group 3 and the first resource in Group 4 have different frequency domain resources. The same applies to the following and will not be repeated. Resource 32 in Group 3 and resource 42 in Group 4 have different frequency domain resources. Resource 33 in Group 3 and resource 43 in Group 4 have different frequency domain resources. Resource 34 in Group 3 and resource 44 in Group 4 have different frequency domain resources. Resource 35 in Group 3 and resource 45 in Group 4 have different frequency domain resources. Furthermore, the frequency domain resource of resource 31 is higher than the frequency domain resource of resource 41. For Group 3, among the five resources it contains, there are two adjacent resources. The frequency domain resource of the first resource has the highest frequency, and the frequency domain resource of the second resource has the lowest frequency. That is, the frequency domain resource of resource 32 has the highest frequency, and the frequency domain resource of resource 33 has the lowest frequency. For group 4, among the five resources it contains, there are two adjacent resources. The frequency domain resource of the first resource is the frequency domain resource with the highest frequency, and the frequency domain resource of the second resource is the frequency domain resource with the lowest frequency. That is, the frequency domain resource of resource 43 is the frequency domain resource with the highest frequency, and the frequency domain resource of resource 44 is the frequency domain resource with the lowest frequency.

[0185] For example, for Groups 4 and 5 in Figure 8 , resource 41 in Group 4 and resource 51 in Group 5 have different frequency domain resources. That is, the first resource in Group 4 and the first resource in Group 5 have different frequency domain resources. The same applies and will not be repeated here. Resource 42 in Group 4 and resource 52 in Group 5 have different frequency domain resources. Resource 43 in Group 4 and resource 53 in Group 5 have different frequency domain resources. Resource 44 in Group 4 and resource 54 in Group 5 have different frequency domain resources. Resource 45 in Group 4 and resource 55 in Group 5 have different frequency domain resources. Furthermore, the frequency domain resource of resource 41 is higher than the frequency domain resource of resource 51. For Group 4, among its five resources, there are two adjacent resources. The frequency domain resource of the first resource has the highest frequency, and the frequency domain resource of the second resource has the lowest frequency. That is, the frequency domain resource of resource 43 has the highest frequency, and the frequency domain resource of resource 44 has the lowest frequency. For group 5, among the five resources it contains, there are two adjacent resources. The frequency domain resource of the first resource is the frequency domain resource with the highest frequency, and the frequency domain resource of the second resource is the frequency domain resource with the lowest frequency. That is, the frequency domain resource of resource 54 is the frequency domain resource with the highest frequency, and the frequency domain resource of resource 55 is the frequency domain resource with the lowest frequency.

[0186] For example, for Groups 5 and 6 in Figure 8 , resource 51 in Group 5 and resource 61 in Group 6 have different frequency domain resources. That is, the first resource in Group 5 and the first resource in Group 6 have different frequency domain resources. The same applies and will not be repeated here. Resource 52 in Group 5 and resource 62 in Group 6 have different frequency domain resources. Resource 53 in Group 5 and resource 63 in Group 6 have different frequency domain resources. Resource 54 in Group 5 and resource 64 in Group 6 have different frequency domain resources. Resource 55 in Group 5 and resource 65 in Group 6 have different frequency domain resources. Furthermore, the frequency domain resource of resource 51 is higher than the frequency domain resource of resource 61. For Group 5, among its five resources, there are two adjacent resources: the first resource has the highest frequency, and the second resource has the lowest frequency. That is, resource #54 has the highest frequency, while resource #55 has the lowest frequency. For group 6, the frequency of the frequency domain resource of the previous resource is lower than the frequency of the frequency domain resource of the next resource, that is, the frequency of the frequency resource of resource 61 is lower than the frequency of the frequency resource of resource 62, the frequency of the frequency resource of resource 62 is lower than the frequency of the frequency resource of resource 63, the frequency of the frequency resource of resource 63 is lower than the frequency of the frequency resource of resource 64, and the frequency of the frequency resource of resource 64 is lower than the frequency of the frequency resource of resource 65.

[0187] Specifically, when M i The frequency domain resource of the mth resource in the resources and M i+1 When the frequency domain resources of the mth resource in the resources are different, 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 is an example in which 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.

[0188] In some embodiments, M i The frequency domain resource of the first resource among the resources is the frequency domain resource with the highest frequency. i+1 The frequency domain resource of the first resource among the resources is the frequency domain resource with the lowest frequency. i The end PRB of the frequency domain resource of the first resource in the resources corresponds to the highest frequency position in all frequency domain resources, M i+1 The starting PRB of the frequency domain resource of the first resource in the resources corresponds to the lowest frequency position in all frequency domain resources. i Resources or M i+1 The frequency of the frequency domain resource of the xth resource among the resources is higher than the frequency of the frequency domain resource of the x+1th resource, where x is any integer greater than or equal to 1 and less than or equal to M-1. Or, in another achievable manner, the M iresources or the M i+1 The frequency domain resource of the yth resource among the resources is the frequency domain resource with the lowest frequency, and the frequency domain resource of the y+1th 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.

[0189] For example, for Group 1 and Group 2 in Figure 10, 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.

Resource 54 in Group 5 and resource 64 in Group 6 have different frequency domain resources. Resource 55 in Group 5 and resource 65 in Group 6 have different frequency domain resources. Furthermore, the frequency domain resource of resource 51 is lower than the frequency domain resource of resource 61. For Group 5, among its five resources, there are two adjacent resources: the first resource has the lowest frequency, and the second resource has the highest frequency. That is, the frequency domain resource of resource #54 has the lowest frequency, while the frequency domain resource of resource 55 has the highest frequency.

[0210] For example, for Group 2 and Group 3 in FIG12 , 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 to the following and will not be repeated.

[0211] For example, for Group 4 and Group 5 in FIG12 , 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 to the following and will not be repeated. 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.

[0212] Specifically, when M i The frequency domain resource of the mth resource in the resources and M i+1 When the frequency domain resources of the mth resource in the resources are the same, M i The frequency domain resource of the first resource among the resources is the same as the frequency domain resource of the Mth resource. i+1 The frequency domain resources of the first resource and the frequency domain resources of the Mth resource 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 the M signals is less than the number of time domain resources occupied by the M signals. The following description takes the case where the number of frequency resources occupied by the M signals is less than the number of time domain resources occupied by the M signals as an example.

[0213] In one achievable approach, M i Resources or M i+1 The frequency domain resources of the first resource and the frequency domain resources of the Mth resource are the frequency domain resources with the lowest frequency. i Resources or M i+1 The frequency domain resource of the M-1th resource among the resources is the frequency domain resource with the highest frequency, and the frequency domain resource of the Mth resource is the frequency domain resource with the lowest frequency.

[0214] Exemplarily, for each 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 resources 11, resources 21, resources 31, resources 41 and resources 51 are the same; the frequency domain resources of resources 12, resources 22, resources 32, resources 42 and resources 52 are the same, the frequency domain resources of resources 13, resources 23, resources 33, resources 43 and resources 53 are the same, the frequency domain resources of resources 14, resources 24, resources 34, resources 44 and resources 54 are the same, the frequency domain resources of resources 15, resources 25, resources 35, resources 45 and resources 55 are the same, and the frequency domain resources of resources 16, resources 26, resources 36, resources 46 and resources 56 are the same. For any group from group 1 to group 5, the frequency domain resources of the first resource and the frequency domain resources of the sixth resource among the six resources contained therein are the frequency domain resources with the lowest frequency. At the same time, the frequency domain resources of the fifth resource are the frequency domain resources with the highest frequency, and the frequency domain resources of the sixth resource are the frequency domain resources with the lowest frequency.

[0215] In another possible implementation, M i Resources or M i+1 The frequency domain resources of the first resource and the frequency domain resources of the Mth resource are the frequency domain resources with the highest frequency. i Resources or M i+1 The frequency domain resource of the M-1th resource among the resources is the frequency domain resource with the lowest frequency, and the frequency domain resource of the Mth resource is the frequency domain resource with the highest frequency.

[0216] Exemplarily, for each group 1 to group 5 in Figure 14, the number of frequency domain resources is less than the number of time domain resources. At the same time, the frequency domain resources of resources 11, resources 21, resources 31, resources 41 and resources 51 are the same; the frequency domain resources of resources 12, resources 22, resources 32, resources 42 and resources 52 are the same, the frequency domain resources of resources 13, resources 23, resources 33, resources 43 and resources 53 are the same, the frequency domain resources of resources 14, resources 24, resources 34, resources 44 and resources 54 are the same, the frequency domain resources of resources 15, resources 25, resources 35, resources 45 and resources 55 are the same, and the frequency domain resources of resources 16, resources 26, resources 36, resources 46 and resources 56 are the same. For each of the six resources in Group 1 to Group 5, the frequency domain resources of the first resource and the frequency domain resources of the sixth resource are the frequency domain resources with the highest frequency. At the same time, the frequency domain resources of the first resource are the frequency domain resources with the lowest frequency, and the frequency domain resources of the second resource are the frequency domain resources with the highest frequency. It can be understood that the above Figures 7 to 14 are only examples and do not limit the scope of protection of this application. That is, the communication method provided by this application is not limited to the periodic frequency hopping patterns shown in Figures 7 to 14 above. As long as the frequency domain resources occupied by the Mth signal in the i-th group of signals and the first signal in the i+1-th group of signals are the same, and inter-cycle frequency hopping is avoided, they all fall within the scope of protection of this application.

[0217] It should be noted that in the present application, the frequency of the frequency domain resources may refer to the frequency of the highest frequency subcarrier among the subcarriers included in the frequency domain resources, or the frequency of the lowest frequency subcarrier, or the frequency of the center subcarrier, or the frequency of other agreed positions. This application does not limit this.

[0218] It should also be noted that Figures 7 through 14 are schematic illustrations only. For ease of illustration, the time span occupied by each frequency domain resource within each time window has been slightly exaggerated, and the time span between time windows has been reduced for clarity. Therefore, the figures are illustrative only and not strictly to scale. It should be understood that the channel information for the multiple frequency hopping resources within each time window can be considered essentially unchanged. However, the channel information varies across different time windows.

[0219] Figure 15 is a schematic flow chart of a second communication method 1500 provided in an embodiment of the present application. As shown in Figure 15, the schematic flow chart is illustrated using the interaction between a first device and a second device as an example, wherein the steps performed by the first device and / or the second device may be performed by a module or unit in the first device and / or the second device, for example, by a chip in the first device and / or the second device.

[0220] Similarly, when method 1500 is applied to a perception scenario, N groups of signals or M signals are perception signals, and the perception signal may refer to a perception reference signal, a positioning reference signal, or a communication signal used for perception, etc., which is not limited in this application. At this time, the first device and the second device may be the same, for example, the first device and the second device are both terminal devices. They may also be different, for example, the first device is a terminal device and the second device is a network device. This part of the description can refer to the description in Figure 5 above and will not be repeated here. Specifically, the method includes the following steps.

[0221] S1501: A first device sends N groups of signals to a second device.

[0222] Before S1501 , method 1500 further includes S1502 , where the first device determines N groups of signals and / or M signals.

[0223] Specifically, S1501 and S1502 may refer to S501 and S502 in FIG5 , respectively, and are not described again here.

[0224] Optionally, before S1502, method 150 may further include S1503, where the first device receives configuration information sent by the third device.

[0225] In one 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 perception scenario (uu interface) in which a base station participates, the base station can configure the UE with a frequency hopping pattern of N groups of reference signals through the configuration information carried in the signaling. The configuration information may include the number of hops (for example, 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 at the start of the first hop, the time slot offset and symbol of each hop compared to the first hop, the number of continuously occupied symbols, etc., and may also provide the minimum frequency or the maximum frequency. In addition, the configuration information also includes the length of each time window in the N time windows and the frequency hopping pattern on each time window.

[0226] Optionally, all time windows can be configured to use a default frequency hopping pattern, such as any one of the frequency hopping patterns in Figures 7 to 14. After the frequency hopping pattern of the first time window is configured, the frequency hopping parameters of subsequent time windows can be determined based on the frequency hopping parameters of the first time window. For example, 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, the number of continuously occupied symbols, and other parameters can directly reuse the first period parameters. It will be understood that the fact that all time windows use the default frequency hopping pattern does not mean that the frequency hopping patterns of all time windows are the same. For example, in the frequency hopping patterns shown in Figures 7 to 12, the frequency hopping patterns used by different time windows may be different.

[0227] In another feasible manner, for SL perception scenarios (PC5 interface), such as UE self-transmission and self-reception, UE self-transmission and other-reception, etc. In this scenario, the UE can adopt an autonomously selected resource allocation method (such as mode 2, which can be referred to the relevant description in the current technology and will not be repeated here), listen to the resource reservation information sent by other UEs and measure the corresponding received power before sending a signal, and select resources that are not reserved by other UEs or are reserved by other UEs but have lower received power, so as to avoid in advance the occupation of the same transmission resources by UEs.

[0228] In order to avoid interference between devices, method 1500 optionally further includes S1504.

[0229] S1504: The first device sends multiple messages, each message in the multiple messages indicating multiple resource reservation periods.

[0230] Specifically, the resource reservation period is defined as the time interval between two resources corresponding to the same frequency domain resources in two adjacent time windows. i The time domain resource of the jth resource and the M of the i+1th group i+1 The time interval between the time domain resources of the p-th resource in the resources, wherein the frequency domain resources of the j-th resource are the same as the frequency domain resources 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.

[0231] Optionally, multiple resource reservation periods may be carried in sidelink control information (SCI), for example, in a resource reservation period field in the SCI. It should be noted that, between any two adjacent time windows, the time intervals between two resources corresponding to the same frequency domain resources may be the same or different. When the time intervals between two resources corresponding to the same frequency domain resources are the same, the resource reservation period field carries one resource reservation period; when they are different, the resource reservation period field carries multiple resource reservation periods.

[0232] In some embodiments, M i The time domain resource of the jth resource of the resource, and M i+1 The time interval between the time domain resources of the pth resource in the resources can be T+T s or T-(M-1)T s 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, T s M i resources or M i+1The time interval between two adjacent time domain resources in M i The starting time of sending a signal is the same as M i+1 It is understood that T can also be M i The end time of sending the signal is the same as M i+1 The interval between the end times of sending the signals, etc., T can also be understood as the length of each time window, or the length of the cycle, which is not limited in this application.

For resources 11 and 25, since the frequency domain resources of resources 11, resources 25, and resources 31 are all the first frequency domain resources among all frequency domain resources (taking the frequency resources as an example, which are sorted from high to low), 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 repeated here), and the resource reservation period represented by it is T+(5-1-2*0)T s , that is, T+4T s For resources 25 and 31, the resource reservation period is T-4T. s .

[0236] In other embodiments, M i The time domain resource of the jth resource of the resource, and M i+1 The time interval between the time domain resources of the pth resource in the resources is T. Where T is M i The starting time of sending a signal is the same as M i+1 It is understood that T can also be M i The end time of sending the signal is the same as M i+1 The interval between the transmission end times of the signals, etc. Or, T is M i The time domain resource of the jth resource of the resource, and M i+1 The time interval between the time domain resources of the j-th resource in the resources, 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 length of the cycle, which is not limited in this application.

[0237] For example, in Group 1, Group 2 and Group 3 of Figure 13, resources 11, resources 21 and resources 31 are the same frequency domain resources. For resources 11 and resources 21, the resource reservation period they represent is T, and for resources 21 and resources 31, the resource reservation period they represent is still T.
