[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on February 7, 2024, with application number 202410176431.7 and application name "A Communication Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0004] As fifth-generation (5G) mobile communication systems evolve toward 5G-advanced (5G-A) technology, integrated communication and perception technology is considered a key technology for expanding the service capabilities of mobile communication networks. The core concept of this integrated communication and perception technology is to add perception capabilities to mobile communication networks, building capabilities such as detection, tracking, and imaging of perceived targets. This allows communication and perception capabilities to be integrated into a single network, achieving harmonious coexistence and mutual benefit. The principle of perception technology is that a transmitting device sends radio waves (i.e., perception signals) in a specific direction. When these radio waves strike the surface of a perceived target, they generate reflected radio waves (i.e., echo signals of the perception signals). The receiving device then receives and processes these reflected waves to obtain perception data, such as the target's location, speed, or type.

[0005] Communication signals usually use orthogonal frequency division multiplexing (OFDM) waveform technology. OFDM waveform technology can construct orthogonal subcarriers in the frequency domain, so that by mapping different modulation symbols on orthogonal subcarriers, different modulation symbols can be sent simultaneously. The current resource allocation method is for OFDM waveforms, that is, resources are configured at the granularity of subcarriers or resource blocks (RBs) including at least one subcarrier. However, in the communication perception integration scenario, in addition to the OFDM waveform, there are other waveforms, such as the chirp multiplexing waveform. It can be seen that the current resource allocation method cannot adapt to the communication perception integration scenario. Summary of the Invention

[0006] The embodiments of the present application provide a communication method and apparatus for adapting resource configuration in a communication-aware integrated scenario.

[0007] In a first aspect, the present application provides a communication method, which can be performed by a first communication device, or by other equipment including the functions of the first communication device, or by a chip system (or, chip) or other functional module, which can realize the functions of the first communication device, and the chip system or functional module is, for example, set in the first communication device.

[0008] Taking the first communication device as the execution subject as an example, the method may include: the first communication device determines N first resource units, and sends a first signal based on the N first resource units. Alternatively, the first communication device sends a first signal, and the first signal occupies N first resource units. The frequency range occupied by the N first resource units in one time unit is equal to the first bandwidth, any first resource unit among the N first resource units includes Q second resource units, and the frequency range occupied by any second resource unit among the Q second resource units in one time unit is equal to the first bandwidth, and both N and Q are positive integers.

[0009] Optionally, the first signal may be used for sensing.

[0010] Optionally, the first bandwidth may be located within a second bandwidth, and the second bandwidth may be a carrier bandwidth, or the second bandwidth may be a bandwidth portion.

[0011] In the above embodiment, resource configuration is performed with the first resource unit as the granularity, the frequency range occupied by N first resource units in one time unit is equal to the first bandwidth, and the frequency range occupied by any one of the Q second resource units included in the first resource unit in one time unit is also equal to the first bandwidth, which means that the frequency of the second resource unit can change with time and can be applied to chirp multiplexing waveforms whose frequency changes with time, thereby being able to adapt to resource configuration in the communication perception integration scenario.

[0012] In one possible implementation, a time unit may be a symbol, the first resource unit occupies one symbol in the time domain, the frequency range of the first resource unit at any time in the symbol may be smaller than the first bandwidth, and the frequency of the second resource unit may be different at different times in the symbol. Alternatively, a time unit may be a symbol, the first resource unit occupies one symbol in the time domain, and the frequency range of the first resource unit at any time in the symbol may be equal to the first bandwidth.

[0013] In one possible implementation, the frequency of the second resource unit increases from a first frequency to a second frequency as time increases within a time unit; or, the frequency of the second resource unit increases from a third frequency to a second frequency and then from the first frequency to a third frequency as time increases within a time unit; wherein the first frequency is the lower boundary of the first bandwidth and the second frequency is the upper boundary of the first bandwidth.

[0014] In a possible implementation, the N first resource units may belong to M first resource units, where a frequency range occupied by the M first resource units in one time unit is equal to the first bandwidth, and M is an integer greater than or equal to N.

[0015] Through the above implementation, the first bandwidth can be divided into M first resource units within a time unit, and N first resource units among the M first resource units are used to carry the first signal.

[0016] In one possible implementation, Q may be greater than 1, and the M first resource units may include P second resource units, where P is an integer greater than or equal to Q. At a first moment in a time unit, the frequency interval of the two second resource units with the smallest frequency interval among the Q second resource units is equal to the frequency interval of the two second resource units with the smallest frequency interval among the P second resource units. Alternatively, at a first moment in a time unit, the frequency interval of the two second resource units with the smallest frequency interval among the Q second resource units is greater than the frequency interval of the two second resource units with the smallest frequency interval among the P second resource units. Alternatively, at the first moment in the one time unit, the frequency interval of the two second resource units with the smallest frequency interval among the Q second resource units is equal to K times the frequency interval of the two second resource units with the smallest frequency interval among the P second resource units, where K is an integer greater than 1.

[0017] Through the above implementation, the N first resource units occupied by the first signal can be distributed in a centralized manner or in a distributed manner in terms of frequency, and the implementation is flexible.

[0018] In a possible implementation, the first communication device may further send first information, or the first communication device may further receive first information, wherein the first information may be used to indicate the first bandwidth.

Alternatively, the first communication device sends a first signal, and the first signal occupies H second resource units. The frequency range occupied by the H second resource units within a time unit is equal to the first bandwidth, and the frequency range occupied by any of the H second resource units within a time unit is equal to the first bandwidth, and H is a positive integer.

They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water; and in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of network devices and terminal devices.

[0091] Network devices and terminal devices can communicate via an air interface protocol. The air interface can be referred to as an air interface. Network devices can communicate with each other via an interface protocol between network devices. Terminal devices can communicate with each other via an interface protocol between terminal devices. Network devices and terminal devices, network devices and network devices, and terminal devices can communicate via licensed spectrum, unlicensed spectrum, or both, without limitation.

[0092] The roles of network devices and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile network device. To terminal devices 120j accessing the wireless access network 100 via 120i, terminal device 120i is a network device. However, to network device 110a, 120i is a terminal device, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via an interface protocol between network devices. In this case, 120i is also a network device relative to 110a. Therefore, both network devices and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with network device functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal device functionality.

[0093] Next, the technical features involved in the embodiments of this application are introduced.

[0094] 1. Communication and perception integration

[0095] As 5G mobile communication systems evolve towards 5G-A technology, integrated communication and perception technology is considered a key technology for expanding the service capabilities of mobile communication networks. The core concept of this integrated communication and perception technology is to add perception capabilities to mobile communication networks, building capabilities such as target detection, tracking, and imaging. This allows communication and perception capabilities to be integrated into a single network, achieving harmonious coexistence and mutual benefit. Figure 2 illustrates a scenario of integrated communication and perception. In Figure 2, solid lines represent communication, and dashed lines represent perception, as an example. As shown in Figure 2, network devices can perceive other objects through autonomous transmission and reception, or while simultaneously communicating with terminal devices. Figure 2 uses a smartphone as the terminal device and drones, pedestrians, and vehicles as examples.

[0096] 2. Single-station and dual-station sensing

[0097] Sensing technology can generally be divided into two modes: single-station sensing and dual-station sensing. In the single-station sensing mode, the transmitting device of the sensing signal and the receiving device of the echo signal of the sensing signal are the same device. In other words, in the single-station sensing mode, the transmitting device must both transmit the sensing signal and receive the echo signal reflected from the sensing signal on the sensing target surface. Therefore, the single-station sensing mode can also be referred to as the self-transmitting and self-receiving mode, without limitation. The dual-station sensing mode means that the transmitting device of the sensing signal and the receiving device of the echo signal of the sensing signal are two different devices. In other words, sensing station A transmits the sensing signal, and the echo signal reflected from the sensing target surface is received by sensing station B. Therefore, the dual-station sensing mode can also be referred to as the A-transmitting, B-receiving mode. It should be noted that the echo signal of the sensing signal is the signal generated by the sensing signal reflecting from the sensing target surface, so this echo signal can still be referred to as the sensing signal.

[0098] FIG3 exemplarily shows a schematic diagram of a perception scenario applicable to the embodiment of the present application. FIG3 provides six perception scenarios applicable to the embodiment of the present application, namely: a scenario in which network device A sends and receives a perception signal by itself, that is, a scenario in which network device A sends a perception signal and receives an echo signal, as shown in (1) in FIG3; a scenario in which terminal device A sends and receives a perception signal by itself, that is, a scenario in which terminal device A sends a perception signal and receives an echo signal, as shown in (2) in FIG3; a scenario in which network device A sends a perception signal and network device B receives an echo signal, as shown in (3) in FIG3; a scenario in which terminal device A sends a perception signal and terminal device B receives an echo signal, as shown in (4) in FIG3; a scenario in which network device A sends a perception signal and terminal device A receives an echo signal, as shown in (5) in FIG3; a scenario in which terminal device A sends a perception signal and network device A receives an echo signal, as shown in (6) in FIG3. FIG3 takes the case where the perception target is a vehicle and the terminal device is a smartphone as an example.

[0099] The sensing target may also be referred to as a target, a detected target, a sensed object, a detected object, or a sensed device, etc., without limitation. The sensing target may be any tangible object in the environment that can reflect electromagnetic waves. For example, the sensing target may be a stationary object such as a mountain, a forest, or a building. For another example, the sensing target may also be a movable object such as a vehicle, a drone, a pedestrian, or a terminal device. The embodiments of the present application do not limit the specific implementation form of the sensing target.

[0100] 3. Orthogonal frequency division multiplexing (OFDM) waveform subcarrier

[0101] Communication signals typically utilize OFDM waveform technology. This OFDM waveform technology can construct orthogonal subcarriers (also referred to as subcarriers under the OFDM waveform, or OFDM waveform subcarriers, etc.) in the frequency domain. By mapping different modulation symbols onto orthogonal subcarriers, different modulation symbols can be transmitted simultaneously. For example, the relationship between the modulation symbol (k) to be transmitted and the signal s(t) using the OFDM waveform can be shown as formula (1).

[0102] Here, ∑·is a summation operation, k is the index of the subcarrier, M is the number of subcarriers, Δf is the subcarrier spacing, t is time, and Δk and Δt are predetermined parameters.

[0103] When a transmitting device uses an OFDM waveform to send a communication signal to a receiving device, the transmitting device can generate an OFDM signal from the modulation symbols to be sent according to the above formula (1), thereby mapping the modulation symbols to be sent onto orthogonal subcarriers to achieve simultaneous transmission of different modulation symbols.

[0104] Currently, the resources occupied by communication signals are primarily configured at the granularity of subcarriers or resource blocks containing at least one subcarrier, which is applicable only to OFDM waveforms. That is, a communication signal is carried by at least one subcarrier, or a communication signal is carried by at least one resource block. The frequency of a subcarrier in a symbol remains constant, or in other words, the frequency of a subcarrier remains constant over time, as shown in (1) in Figure 4.

[0105] In addition to OFDM waveforms, other waveforms may also exist in the integrated communication and perception scenario, such as chirp multiplexing waveforms. In the chirp multiplexing waveform technology, chirp multiplexing is used in the time domain and frequency domain, so that the perception signal can occupy more bandwidth within one symbol, which is conducive to improving the perception performance. That is, in the chirp multiplexing waveform technology, the frequency domain resources mapped by a modulation symbol change with time and can occupy more bandwidth, as shown in (2) in Figure 4. It can be seen that the current resource configuration method cannot adapt to the resource configuration in the scenario where multiple waveforms coexist, such as the resource configuration in the integrated communication and perception scenario.

[0106] In view of this, embodiments of the present application provide a communication method and apparatus for adapting resource configuration in a communication-aware integrated scenario. The method and apparatus described herein are based on the same technical concept. Since the method and apparatus solve similar problems, the implementation of the apparatus and method can refer to each other, and any repetitions will not be repeated.

[0107] The following is an introduction to some technical terms involved in the embodiments of this application.

[0108] The first signal can be used for perception. For example, the first signal can be called a perception signal, without limitation. Exemplarily, the first signal can be a physical broadcast channel (PBCH); or it can be a reference signal (for example, a demodulation reference signal (DMRS), a channel state information reference signal (CSI RS), a sounding reference signal (SRS), or other reference signals, etc.); or it can be a downlink channel (for example, a physical downlink control channel (PDCCH), or a physical downlink shared channel (PDSCH)); or it can be an uplink channel (for example, a physical uplink control channel (PUCCH), or a physical uplink shared channel (PUSCH)), etc. The embodiment of the present application does not limit the specific implementation form of the first signal. The embodiment of the present application describes the application of the first signal to the communication perception integration scenario as an example. It should be understood that the first signal can also be applied to various other waveform coexistence scenarios other than the communication perception integration scenario, without limitation.

[0109] A first communication device can be used to send a first signal. The first communication device can be a network device or a component in a network device (such as a DU and / or RU, etc.), or can also be a terminal device or a component in a terminal device, without limitation. For example, the first communication device can be the network device A in (1), (3), or (5) in Figure 3, or can be the terminal device A in (2), (4), or (6) in Figure 3.

[0110] The second communication device can be used to receive the first signal. The second communication device can be a network device or a component in the network device (such as DU and / or RU, etc.), or it can also be a terminal device or a component in the terminal device, without limitation. For example, the first communication device is used to send the first signal, and the second communication device can be used to receive the first signal. For example, the second communication device can be the network device A in (1) or (6) in Figure 3, or the terminal device A in (2) or (5) in Figure 3, or the network device B in (3) in Figure 3, or the terminal device B in (4) in Figure 3.

[0111] Among them, the description of the network device and the terminal device can refer to the relevant content shown in Figure 1, which will not be repeated here.

[0112] Resources may include time domain resources, or frequency domain resources, or time domain resources and frequency domain resources. In the embodiment of the present application, the description is made by taking the case where resources include frequency domain resources, or include time domain resources and frequency domain resources as an example. Among them, time domain resources may include symbols, slots, mini-slots, partial slots, sub-frames, radio frames, or sensing slots, etc., without limitation. Frequency domain resources may include resource elements (RE), resource blocks (RB), RB sets, subchannels, resource pools, bandwidth parts (BWP), carriers, subcarriers, channels, or interlaces, etc., without limitation.

[0113] A time unit may be one or more symbols, or one or more time slots, or one or more micro-time slots, or one or more subframes, or one or more radio frames, etc. The embodiment of the present application does not limit the time domain granularity. Among them, multiple time units may be continuous or discrete in time, without limitation. Among them, the symbol may be an OFDM symbol, or the symbol may be an OFDM symbol based on discrete Fourier transform (discrete fourier transform-spread-OFDM, DFT-S-OFDM) symbol. The embodiment of the present application does not limit the specific implementation form of the symbol.

[0114] Figure 5 exemplarily shows a flow chart of a communication method provided by an embodiment of the present application. As shown in Figure 5 , the method may include the following contents.

[0115] S501: A first communication device sends a first signal.

[0116] Exemplarily, the first communication device may determine a resource for transmitting (or carrying) a first signal and use the resource to send the first signal. The first signal may be used for sensing. For details, please refer to the terminology introduction and will not be repeated here.

[0117] The embodiment of the present application provides two resource configuration methods, namely: resource configuration with a first resource unit as the granularity and resource configuration with a second resource unit as the granularity. The first resource unit and the second resource unit are introduced below.

[0118] 1. The first resource unit may also be referred to as a chirp resource block, or a resource block, etc. The embodiments of the present application do not limit the specific naming of the first resource unit. In the time domain, the first resource unit may occupy one time unit. For example, one time unit may be one symbol (for example, an OFDM symbol), and the first resource unit may occupy one symbol in the time domain. In the frequency domain, the first resource unit may include one or more second resource units, such as Q second resource units. That is, the first resource unit may include Q second resource units in the frequency domain. Wherein, Q is a positive integer. For example, Q may be 4, or a power of 2 (for example, 4, 8, 16, or 32, etc.), or a multiple of 10 (for example, 10, 20, or 30, etc.), or a multiple of 12 (for example, 12, 24, or 36, etc.), without limitation.

[0119] The frequency range occupied by the first resource unit in one time unit is equal to the first bandwidth. In one example, the frequency range of the first resource unit at any moment in one time unit is smaller than the first bandwidth. For example, one time unit is one symbol, and the frequency range of the first resource unit at any moment in one symbol is smaller than the first bandwidth. In another example, the frequency range of the first resource unit at any moment in one time unit may also be equal to the first bandwidth, that is, the resources are configured for the first signal with the first bandwidth as the granularity. For example, one time unit is one symbol, and the frequency of the first resource unit at any moment in one symbol is equal to the first bandwidth. For ease of understanding, the following description will be based on the example that the frequency range of the first resource unit at any moment in one time unit is smaller than the first bandwidth.

[0120] 2. The second resource unit may also be referred to as a subresource unit, a frequency domain unit, a chirped subcarrier, or a subcarrier, etc. The embodiment of the present application does not limit the specific naming of the second resource unit. The frequency range occupied by the second resource unit in one time unit is equal to the first bandwidth, as shown in Figure 6. For example, one time unit is one symbol, and the frequency range occupied by the second resource unit in one symbol is equal to the first bandwidth. Figure 6 takes the example of the second resource unit being called a chirped subcarrier. In the embodiment of the present application, the frequency ranges occupied by the first resource unit and the second resource unit in one time unit are both equal to the first bandwidth, which means that the frequency of the second resource unit can change over time.

[0121] Exemplarily, the frequency of the second resource unit may be different at different times within a time unit. For example, where a time unit is a symbol, the frequency of the second resource unit may be different at different times within the symbol. For example, assuming the second resource unit is chirped subcarrier 1, and time 1 and time 2 are different times within a time unit, the frequency of the chirped subcarrier at time 1 is different from the frequency of the chirped subcarrier at time 2, as shown in FIG6 , for chirped subcarrier 1 and chirped subcarrier 2.

[0122] In one possible design, the frequency of the second resource unit may increase from the lower boundary of the first bandwidth (for example, denoted as the first frequency, i.e., the first frequency is the minimum frequency in the first bandwidth) to the upper boundary of the first bandwidth (for example, denoted as the second frequency, i.e., the second frequency is the maximum frequency in the first bandwidth) as time increases within a time unit, as shown in chirped subcarrier 1 in FIG6 . In another possible design, the frequency of the second resource unit may increase from the third frequency to the second frequency (i.e., the upper boundary of the first bandwidth), and then from the first frequency (i.e., the lower boundary of the first bandwidth) to the third frequency as time increases within a time unit, as shown in chirped subcarrier 2 in FIG6 . The third frequency is greater than the first frequency and less than the second frequency.

[0123] The hollow circles in Figure 6 indicate that if the frequency of the second resource unit is equal to the third frequency at the start of a time unit, then the frequency of the second resource unit is close to the third frequency (for example, less than the third frequency) but not equal to the third frequency at the end of the time unit. Alternatively, if the frequency of the second resource unit is close to the third frequency (for example, greater than the third frequency) but not equal to the third frequency at the start of a time unit, then the frequency of the second resource unit is equal to the third frequency at the end of the time unit. In addition, Figure 6 shows an example in which the frequency of the chirped subcarrier 2 at time 1 is the second frequency. It should be understood that if the frequency of the chirped subcarrier 2 at time 1 is equal to the second frequency, then at a time close to time 1 (for example, after time 1), the frequency of the chirped subcarrier 2 is equal to the first frequency.

[0124] It should be noted that the moment in the embodiment of the present application can be understood as a sampling point or a sampling time point, or can also be understood as a time concept with a smaller granularity than a time unit, such as the moment 1 shown in FIG6 .

[0125] Among them, the first bandwidth can be used for perception. The first bandwidth can also be called chirp bandwidth, perception bandwidth, etc. The embodiment of the present application does not limit the specific naming of the first bandwidth. In one example, the first bandwidth can be located within the second bandwidth. The second bandwidth can include the bandwidth for sending signals, or the second bandwidth can include the bandwidth for receiving signals, or the second bandwidth can include the bandwidth for sending signals and the bandwidth for receiving signals. For example, the second bandwidth can include one or more of the following: the bandwidth for receiving signals on the first communication device side, the bandwidth for sending signals on the first communication device side, the bandwidth for receiving signals on the second communication device side, or the bandwidth for sending signals on the second communication device side. For another example, the second bandwidth can be a carrier bandwidth, or it can also be a bandwidth part, without limitation. For example, the second bandwidth can include the first bandwidth for perception and the third bandwidth for communication, as shown in Figure 7. In another example, the first bandwidth can also be equal to the second bandwidth.

[0126] The first bandwidth may be predefined, or may be configured (or allocated) by the first communication device, or may be configured (or allocated) by other communication devices other than the first communication device (for example, recorded as a third communication device), without limitation. The third communication device may be a network device or a component in a network device, or may be a terminal device or a component in a terminal device. The embodiment of the present application does not limit the specific implementation form of the third communication device. For example, the third communication device may be a second communication device, or may be other communication devices other than the first communication device and the second communication device (for example, the first communication device and the second communication device are both terminal devices, and the third communication device may be a network device or other terminal device).

[0127] In one possible implementation, a first communication device may send first information, which may be used to indicate a first bandwidth. For example, the first bandwidth is configured by the first communication device, which may send the first information. For example, the first communication device may send the first information to a second communication device; in turn, the second communication device may receive the first information from the first communication device. Furthermore, the second communication device may determine the first bandwidth based on the first information.

[0128] In another possible implementation, a first communication device may receive first information, which may be used to indicate a first bandwidth. For example, the first bandwidth is configured by a third communication device, which may receive the first information. For example, the third communication device may send the first information to the first communication device; in response, the first communication device may receive the first information from the third communication device. Furthermore, the first communication device may determine the first bandwidth based on the first information. For another example, if the third communication device is not the second communication device, the third communication device may also send the first information to the second communication device; in response, the second communication device may receive the first information from the third communication device. Furthermore, the second communication device may determine the first bandwidth based on the first information.

[0129] In one possible implementation, the first information used to indicate the first bandwidth may specifically include: the first information may be used to indicate the upper boundary of the first bandwidth and the lower boundary of the first bandwidth; or, the first information may be used to indicate the upper boundary of the first bandwidth and the width of the first bandwidth; or, the first information may be used to indicate the lower boundary of the first bandwidth and the width of the first bandwidth; or, the first information may be used to indicate the frequency interval between the upper boundary of the first bandwidth and the upper boundary of the second bandwidth and the frequency interval between the lower boundary of the first bandwidth and the lower boundary of the second bandwidth; or, the first information may be used to indicate the frequency interval between the upper boundary of the first bandwidth and the upper boundary of the second bandwidth and the width of the first bandwidth; or, the first information may be used to indicate the frequency interval between the lower boundary of the first bandwidth and the lower boundary of the second bandwidth and the width of the first bandwidth, etc. It is understandable that the embodiments of the present application do not limit the specific implementation of the first information.

[0130] Optionally, the first information may be carried by RRC layer signaling, or may be carried by MAC layer signaling, without limitation.

[0131] Next, two resource configuration methods provided in the embodiments of the present application (for example, respectively referred to as resource configuration method 1 and resource configuration method 2) are introduced.

[0132] 1. Resource allocation method 1

[0133] In resource configuration mode 1, the first signal can occupy N first resource units. FIG5 is taken as an example of the first signal occupying N first resource units. Accordingly, the first communication device can send the first signal based on the N first resource units. N is a positive integer. The frequency range occupied by the N first resource units in one time unit is equal to the first bandwidth. Any first resource unit among the N first resource units includes Q second resource units, and the frequency range occupied by any second resource unit among the Q second resource units in one time unit is also equal to the first bandwidth. Among them, please refer to the above content for the first resource unit, the second resource unit, and the first bandwidth, which will not be repeated here.

[0134] In one possible implementation, the N first resource units may belong to M first resource units, that is, the M first resource units include the N first resource units. The frequency unit occupied by the M first resource units in one time unit is equal to the first bandwidth. M is an integer greater than or equal to N. The M first resource units can be understood as: the first resource units included in the first bandwidth in one time unit. That is, the first bandwidth can be divided into M first resource units in one time unit. Accordingly, the first resource unit occupied by the first signal may be the M first resource units, or it may be part of the M first resource units.

[0135] Any of the N first resource units occupied by the first signal can be distributed (or allocated) in a centralized manner, or can also be distributed (or allocated) without limitation. Assuming that Q is greater than 1, the M first resource units include P second resource units, where P is an integer greater than or equal to Q. In one possible design, at the first moment in a time unit, the frequency interval of the two second resource units with the smallest frequency interval among the Q second resource units is equal to the frequency interval of the two second resource units with the smallest frequency interval among the P second resource units, as shown in (1) in Figure 8; in other words, the Q second resource units are consecutive Q second resource units, for example, Q second resource units with consecutive numbers (or index numbers). Figure 8 takes the example of a first resource unit being called a chirped resource block and a second resource unit being a chirped subcarrier. As shown in (1) in FIG8 , the first bandwidth is divided into two chirped resource blocks within a time unit, i.e., M is 2, which are respectively denoted as chirped resource block 1 and chirped resource block 2. Each chirped resource block includes three chirped subcarriers (i.e., Q is 3 and P is 6). The frequency interval of the two chirped subcarriers with the smallest frequency interval at the first moment among the six chirped subcarriers included in the chirped resource block 1 and the chirped resource block 2 is frequency interval 1. The frequency interval of the two chirped subcarriers with the smallest frequency interval at the first moment among the three chirped subcarriers included in the chirped resource block 1 (or chirped resource block 2) is also frequency interval 1.

[0136] Among them, the first moment is any moment in a time unit. For the description of the moments, please refer to the above content and will not be repeated here. Figure 8 shows the example of the first moment being the starting moment of a time unit. Among them, the two second resource units with the smallest frequency interval can be understood as: two adjacent second resource units. For example, two second resource units with adjacent numbers (or index numbers). It can be understood that if the first resource unit includes two second resource units, then these two second resource units can be the two second resource units with the smallest frequency interval at the first moment; or if the number of second resource units included in the first resource unit is greater than 2, then there can be multiple groups of the two second resource units with the smallest frequency interval at the first moment in the first resource unit.

[0137] In another possible design, at the first moment in a time unit, the frequency interval between the two second resource units with the smallest frequency interval among the Q second resource units is greater than the frequency interval between the two second resource units with the smallest frequency interval among the P second resource units, as shown in (2) or (3) in Figure 8; or in other words, the Q second resource units are discontinuous Q second resource units, for example, Q second resource units with discontinuous numbers (or index numbers). As shown in (2) in Figure 8, the first bandwidth is divided into two chirped resource blocks within a time unit, that is, M is 2, respectively denoted as chirped resource block 1 and chirped resource block 2, and each chirped resource block includes 3 chirped subcarriers (that is, Q is 3 and P is 6). The frequency interval of the two chirped subcarriers with the smallest frequency interval at the first moment among the six chirped subcarriers included in the chirped resource block 1 and the chirped resource block 2 is frequency interval 1, and the frequency interval of the two chirped subcarriers with the smallest frequency interval at the first moment among the three chirped subcarriers included in the chirped resource block 1 (or chirped resource block 2) is frequency interval 2, and the frequency interval 2 is greater than the frequency interval 1.

[0138] As shown in (3) in FIG8 , the first bandwidth is divided into three chirped resource blocks within a time unit, i.e., M is 3, which are respectively recorded as chirped resource block 1, chirped resource block 2, and chirped resource block 3. Each chirped resource block includes two chirped subcarriers (i.e., Q is 3, P is 6). The frequency interval of the two chirped subcarriers with the smallest frequency interval at the first moment among the six chirped subcarriers included in chirped resource block 1, chirped resource block 2, and chirped resource block 3 is frequency interval 1. The frequency interval of the two chirped subcarriers with the smallest frequency interval at the first moment among the two chirped subcarriers included in chirped resource block 1 (or chirped resource block 2, or chirped resource block 3) is frequency interval 3, and frequency interval 3 is larger than frequency interval 1.

[0139] Optionally, in (2) or (3) of FIG8 , at a first moment, the frequency spacing of the two chirped subcarriers with the minimum frequency spacing between the chirped subcarriers in chirped resource block 1 and the chirped subcarriers in chirped resource block 2 is equal to the frequency spacing of the two chirped subcarriers with the minimum frequency spacing among the P chirped subcarriers. Optionally, in (3) of FIG8 , at a first moment, the frequency spacing of the two chirped subcarriers with the minimum frequency spacing between the chirped subcarriers in chirped resource block 1 and the chirped subcarriers in chirped resource block 3 is equal to the frequency spacing of the two chirped subcarriers with the minimum frequency spacing among the P chirped subcarriers. Optionally, in (3) of Figure 8, at the first moment, the frequency interval of the two chirped subcarriers with the minimum frequency interval between the chirped subcarrier in chirped resource block 2 and the chirped subcarrier in chirped resource block 3 is equal to the frequency interval of the two chirped subcarriers with the smallest frequency interval among the P chirped subcarriers.

[0140] In another possible design, at the first moment in a time unit, the frequency interval between the two second resource units with the smallest frequency interval among the Q second resource units is equal to K times the frequency interval between the two second resource units with the smallest frequency interval among the P second resource units. The K may be 1, as shown in (1) in FIG8 . Or the K may be greater than 1, as shown in (2) or (3) in FIG8 . Optionally, the K may be a multiple of 2 (for example, 4, 6, 8, or 10, etc.), or a multiple of 3 (for example, 3, 6, 9, or 12, etc.), or a multiple of 5 (for example, 5, 10, 15, or 20, etc.), or a multiple of 10 (for example, 10, 20, 30, or 40, etc.), without limitation.

[0141] The N first resource units may be predefined, or may be configured (or allocated) by the first communication device, or may be configured (or allocated) by a third communication device, without limitation. For a description of the third communication device, please refer to the aforementioned content and will not be repeated here. For example, the first communication device may determine the N first resource units.

[0142] In one possible implementation, a first communication device may transmit second information, which may be used to indicate the N first resource units. For example, the N first resource units are configured by the first communication device, and the first communication device may transmit the second information. For example, the first communication device may transmit the second information to the second communication device; in response, the second communication device may receive the second information from the first communication device. Furthermore, the second communication device may determine the N first resource units based on the second information.

[0143] In another possible implementation, the first communication device may receive second information, which may be used to indicate N first resource units. For example, the N first resource units are configured by a third communication device, and the first communication device may receive the second information. For example, the third communication device may send the second information to the first communication device; accordingly, the first communication device may receive the second information from the third communication device. Further, the first communication device may determine the N first resource units based on the second information. For another example, if the third communication device is not the second communication device, the third communication device may also send the second information to the second communication device; accordingly, the second communication device may receive the second information from the third communication device. Further, the second communication device may determine the N first resource units based on the second information.

[0144] In one possible implementation, the second information is used to indicate the N first resource units. Specifically, the second information may be used to indicate the starting position and number of the N first resource units. Alternatively, the second information may indicate the N first resource units in a bitmap format. It is understood that the embodiments of the present application do not limit the specific implementation of the second information.

[0145] Optionally, the second information may be carried by downlink control information (DCI) without limitation.

[0146] In the above-mentioned resource configuration method 1, resource configuration is performed with the first resource unit as the granularity. The frequency range occupied by N first resource units in one time unit is equal to the first bandwidth, and the frequency range occupied by any one of the Q second resource units included in the first resource unit in one time unit is also equal to the first bandwidth, which means that the frequency of the second resource unit can change with time and can be applied to chirp multiplexing waveforms whose frequency changes with time, so that it can adapt to resource configuration in the integrated communication and perception scenario.

[0147] 2. Resource allocation method 2

[0148] In resource configuration mode 2, the first signal may occupy H second resource units. Accordingly, the first communication device may send the first signal based on the H second resource units. H is a positive integer. The frequency range occupied by the H second resource units in one time unit is equal to the first bandwidth, and the frequency range occupied by any second resource unit in the H second resource units in one time unit is also equal to the first bandwidth. Please refer to the aforementioned content for the second resource units and the first bandwidth, and will not be repeated here.

[0149] In one example, the frequency range of the H second resource units at any moment in a time unit may be smaller than the first bandwidth. For example, one time unit is a symbol, and the frequency range of the H second resource units at any moment in a symbol may be smaller than the first bandwidth. In another example, the frequency range of the H second resource units at any moment in a time unit may also be equal to the first bandwidth, that is, the resources are configured for the first signal with the first bandwidth as the granularity. For example, one time unit is a symbol, and the frequency of the H second resource units at any moment in a symbol is equal to the first bandwidth. For ease of understanding, the following description will be based on the example that the frequency range of the H second resource units at any moment in a time unit is smaller than the first bandwidth.

[0150] In one possible implementation, the H second resource units may belong to P second resource units, that is, the P second resource units include the H second resource units. The frequency unit occupied by the P second resource units in one time unit is equal to the first bandwidth. P is an integer greater than or equal to H. The P second resource units can be understood as: the second resource units included in the first bandwidth in one time unit. That is, the first bandwidth can be divided into P second resource units in one time unit. Accordingly, the second resource unit occupied by the first signal may be the P second resource units, or may be part of the P second resource units.

[0151] Assuming that H is greater than 1, the H second resource units occupied by the first signal can be distributed (or allocated) in a centralized manner, or can also be distributed (or allocated) without restriction. In one possible design, at the second moment in a time unit, the frequency interval of the two second resource units with the smallest frequency interval among the H second resource units is equal to the frequency interval of the two second resource units with the smallest frequency interval among the P second resource units, as shown in (1) in Figure 9; in other words, the H second resource units are H consecutive second resource units, for example, H second resource units with consecutive numbers (or index numbers). Figure 9 takes the chirped subcarrier as an example. As shown in (1) in Figure 9, the first bandwidth is divided into 6 chirped subcarriers (i.e., P is 6) in a time unit, and the first signal occupies 3 of the chirped subcarriers (i.e., H is 3). Among them, the frequency interval of the two chirped subcarriers with the smallest frequency interval at the second moment among the P chirped subcarriers is frequency interval 1, and the frequency interval of the two chirped subcarriers with the smallest frequency interval at the second moment among the three chirped subcarriers occupied by the first signal is also frequency interval 1.

[0152] Among them, the second moment is any moment in a time unit. For the description of the moments, please refer to the above content and will not be repeated here. Figure 9 shows the second moment as the starting moment of a time unit as an example. Among them, the two second resource units with the smallest frequency interval can be understood as: two adjacent second resource units. For example, two second resource units with adjacent numbers (or index numbers). It can be understood that if H is greater than 2, then there can be multiple groups of two second resource units with the smallest frequency interval at the second moment among the H second resource units.

[0153] In another possible design, at the second time in a time unit, the frequency interval of the two second resource units with the smallest frequency interval among the H second resource units is greater than the frequency interval of the two second resource units with the smallest frequency interval among the P second resource units, which can be referred to (2) or (3) in Figure 9; in other words, the H second resource units are H discontinuous second resource units, for example, H second resource units with discontinuous numbers (or index numbers). As shown in (2) in Figure 9, the first bandwidth is divided into 6 chirped subcarriers in a time unit (i.e., P is 6), and the first signal occupies 3 of the chirped subcarriers (i.e., H is 3). Among them, the frequency interval of the two chirped subcarriers with the smallest frequency interval at the second moment among the P chirped subcarriers is also frequency interval 1, and the frequency interval of the two chirped subcarriers with the smallest frequency interval at the second moment among the 3 chirped subcarriers occupied by the first signal is frequency interval 2, and this frequency interval 2 is greater than frequency interval 1.

[0154] As shown in (3) in FIG9 , the first bandwidth is divided into 6 chirped subcarriers within a time unit (i.e., P is 6), and the first signal occupies 2 of the chirped subcarriers (i.e., H is 2). Among them, the frequency interval between the two chirped subcarriers with the smallest frequency interval at the second moment among the P chirped subcarriers is also frequency interval 1, and the frequency interval between the two chirped subcarriers with the smallest frequency interval at the second moment among the two chirped subcarriers occupied by the first signal is frequency interval 3, which is greater than frequency interval 1.

[0155] In another possible design, at the second moment in a time unit, the frequency interval between the two second resource units with the smallest frequency interval among the H second resource units is equal to J times the frequency interval between the two second resource units with the smallest frequency interval among the P second resource units. The J can be 1, as shown in (1) in Figure 9. Or the J can also be greater than 1, as shown in (2) or (3) in Figure 9. Optionally, the J can be a multiple of 2 (for example, 4, 6, 8, or 10, etc.), or a multiple of 3 (for example, 3, 6, 9, or 12, etc.), or a multiple of 5 (for example, 5, 10, 15, or 20, etc.), or a multiple of 10, etc. (for example, 10, 20, 30, or 40, etc.), without limitation.

[0156] The H second resource units may be predefined, or may be configured (or allocated) by the first communication device, or may be configured (or allocated) by a third communication device, without limitation. For a description of the third communication device, please refer to the aforementioned content and will not be repeated here. For example, the first communication device may determine the H second resource units.

[0157] In one possible implementation, the first communication device may transmit third information, which may be used to indicate H second resource units. For example, the H second resource units are configured by the first communication device, and the first communication device may transmit the third information. For example, the first communication device may transmit the third information to the second communication device; in response, the second communication device may receive the third information from the first communication device. Furthermore, the second communication device may determine the H second resource units based on the third information.

[0158] In another possible implementation, the first communication device may receive third information, which may be used to indicate H second resource units. For example, the H second resource units are configured by a third communication device, and the first communication device may receive the third information. For example, the third communication device may send the third information to the first communication device; accordingly, the first communication device may receive the third information from the third communication device. Further, the first communication device may determine the H second resource units based on the third information. For another example, if the third communication device is not the second communication device, the third communication device may also send the third information to the second communication device; accordingly, the second communication device may receive the third information from the third communication device. Further, the second communication device may determine the H second resource units based on the third information.

[0159] In one possible implementation, the third information used to indicate the H second resource units may specifically include: the third information may be used to indicate the starting second resource unit and the number of the H second resource units; or the third information may also indicate the H second resource units in a bitmap manner, etc. It will be understood that the embodiments of the present application do not limit the specific implementation form of the third information.

[0160] Optionally, the third information may be carried by downlink control information (DCI) without limitation.

[0161] In the above-mentioned resource configuration method 2, resource configuration is performed with the second resource unit as the granularity, and the frequency range occupied by the second resource unit in one time unit is also equal to the first bandwidth, which means that the frequency of the second resource unit can change with time, and can be applied to the chirp multiplexing waveform whose frequency changes with time, thereby being able to adapt to the resource configuration in the integrated communication perception scenario.

[0162] S502: The second communication device receives the first signal.

[0163] Alternatively, the second communication device may also receive an echo signal of the first signal.

[0164] Exemplarily, the second communication device may determine the resources for transmitting (or carrying) the first signal, and receive the first signal based on the resources. For example, the second communication device may receive or send first information, and the first information is used to indicate the first bandwidth. For details, please refer to the relevant content of S501, which will not be repeated. As an example, if resource configuration method 1 is used to configure resources for the first signal, the second communication device may determine N first resource units. For example, the second communication device may receive or send second information, and the second information may be used to indicate N first resource units. For details, please refer to the relevant content of S501, which will not be repeated. As another example, if resource configuration method 2 is used to configure resources for the first signal, the second communication device may determine H second resource units. For example, the second communication device may receive or send third information, and the third information may be used to indicate H second resource units.
