[0004] Communication-sensing integration combines wireless communication and sensing functions into a single system. It utilizes the various propagation characteristics of wireless signals to achieve sensing functions such as target localization, detection, imaging, and identification, thereby acquiring information about the surrounding physical environment, improving communication performance, and enhancing user experience. In communication-sensing integration technology, sensing signals can be used to obtain information such as the position and velocity of targets in the environment, while communication signals can be used to achieve communication functions such as measurement, data transmission, and control signaling transmission. The resources carrying sensing signals are called sensing resources, and the resources carrying communication signals are called communication resources.

[0005] Currently, there are no design schemes for sensing and communication resources, and how to design sensing and communication resources has become an urgent problem to be solved. Summary of the Invention

[0007] In a first aspect, this application provides a sensing method that can be applied to a first device. The first device is, for example, a terminal-side device or a network-side device. The terminal-side device is also referred to as a terminal device or a terminal.

[0008] The terminal device may be, for example, a terminal equipment, or a component of a terminal equipment, such as a communication module, circuits or chips responsible for communication functions (e.g., modem chips, also known as baseband chips, or system-on-chip (SoC) chips containing modem cores, or system-in-package (SIP) chips, chip systems, or processors, etc.) or other functional modules that can be applied in the terminal equipment. This chip system or functional module can realize the functions of the terminal equipment. For example, if the chip system or functional module is located in the terminal equipment, it can also be a logic module or software that can realize all or part of the functions of the terminal equipment.

[0009] The network-side device is also referred to as a network device. This network device is, for example, a network equipment, or a component of a network equipment, such as a communication module, circuitry or chip responsible for communication functions (e.g., a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core, a chip system, or a processor, etc.) or other functional module that can be applied within the network equipment. This chip system or functional module can implement the functions of the network equipment. This chip system or functional module, for example, is located within the network equipment and can also be a logic module or software that can implement all or part of the functions of the network equipment. Optionally, the network equipment can be an Open Radio Access Network (ORAN) architecture or an ORAN architecture; or, the network equipment can be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU) under an ORAN architecture. The network equipment is, for example, located on the ground, or it can be, for example, a satellite or an aircraft, or a non-ground device. The network equipment includes, for example, access network equipment and / or core network equipment.

[0010] The method may include: determining a first frequency domain resource, the first frequency domain resource being used to carry a first signal, the first signal being used to determine information about a sensing target, wherein the first frequency domain resource includes a first sub-frequency domain resource, the first sub-frequency domain resource being used to carry a second signal, the second signal being used for communication; transmitting the first signal, or transmitting the second signal.

[0013] In the above method, the first signal is carried by a first frequency domain resource and is used for sensing; the second signal is carried by a first sub-frequency domain resource and is used for communication. The first frequency domain resource includes the first sub-frequency domain resource, thus realizing the design of sensing and communication resources. Furthermore, the inclusion of the first sub-frequency domain resource in the first frequency domain resource means that both sensing and communication signals can be transmitted on the first frequency domain resource, saving signaling and resource overhead and improving spectral efficiency. Additionally, if the first frequency domain resource is larger than the first sub-frequency domain resource (i.e., the first sub-frequency domain resource is a portion of the first frequency domain resource), the frequency domain resource occupied by the sensing signal is larger than that occupied by the communication signal, allowing the sensing signal to be transmitted over a wider bandwidth. Generally, a wider bandwidth results in better sensing performance; therefore, the above method can also improve sensing performance, such as increasing ranging accuracy.

[0014] In one possible implementation, the method may further include receiving a third signal, wherein the third signal includes an echo signal of the first signal, or the third signal includes an echo signal of the second signal. For example, a first device can receive a third signal, which includes an echo signal of the first signal, after transmitting a first signal. As another example, a first device can receive a third signal, which includes an echo signal of the second signal, after transmitting a second signal, which can be used for sensing and communication.

[0020] The method may include: determining a first bandwidth for carrying sensing signals, wherein the first bandwidth includes a second bandwidth for carrying communication signals; transmitting a first signal in the first bandwidth for determining information about a sensing target, or transmitting a fifth signal in the second bandwidth for sensing and / or communication.

[0022] Alternatively, the method may include: determining a first bandwidth and a second bandwidth, the first bandwidth including the second bandwidth, the first bandwidth being used to carry sensing signals and the second bandwidth being used to carry communication signals; transmitting a first signal in the first bandwidth, the first signal being used to determine information about a sensing target, or transmitting a fifth signal in the second bandwidth, the fifth signal being used for sensing and / or communication.

[0023] In the above method, the sensing signal is carried by a first bandwidth, and the communication signal is carried by a second bandwidth. The first bandwidth includes the second bandwidth, thus realizing the design of sensing and communication resources. Furthermore, the fact that the first bandwidth includes the second bandwidth means that the first bandwidth can transmit both sensing and communication signals, saving signaling overhead and increasing spectral efficiency. Additionally, if the second bandwidth is a portion of the frequency domain resources within the first bandwidth, the frequency domain resources occupied by the sensing signal are greater than those occupied by the communication signal, allowing the sensing signal to be transmitted over a wider bandwidth. Generally, a wider bandwidth results in better sensing performance; therefore, the above method can also improve sensing performance, such as increasing ranging accuracy.

[0024] In one possible implementation, the method may further include receiving a sixth signal, wherein the sixth signal includes an echo signal of the first signal, or the sixth signal includes an echo signal of the fifth signal. For example, a first device transmitting a first signal may receive a sixth signal, which includes an echo signal of the first signal. As another example, a first device transmitting a fifth signal may receive a sixth signal, which includes an echo signal of the fifth signal, and the fifth signal may be used for sensing and communication.

[0025] In one possible implementation, the first bandwidth may include a first frequency domain resource for carrying the first signal, and the second bandwidth may include a first sub-frequency domain resource for carrying the fifth signal, wherein the first frequency domain resource includes the first sub-frequency domain resource.

[0026] In one possible implementation, the fifth signal can be the second signal.

[0027] Fourthly, this application provides a sensing method that can be applied to a second device. The second device may be, for example, a terminal-side device or a network-side device. For a description of the terminal-side device or network-side device, please refer to the first aspect, and it will not be repeated here. For example, the first device may be a terminal-side device and the second device may be a network-side device; or, the first device may be a network-side device and the second device may be a terminal-side device; or, both the first device and the second device may be terminal-side devices; or, both the first device and the second device may be network-side devices.

[0028] The method may include: determining a first bandwidth for carrying a sensing signal, wherein the first bandwidth includes a second bandwidth for carrying a communication signal; receiving a seventh signal, wherein the seventh signal includes an echo signal of the first signal, or the seventh signal includes an echo signal of the fifth signal, or the seventh signal is the fifth signal, wherein the first signal is carried in the first bandwidth, the first signal is used to determine information about the sensing target, the fifth signal is carried in the second bandwidth, and the fifth signal is used for sensing and / or communication.

[0029] Alternatively, the method may include: determining a second bandwidth for carrying communication signals, wherein the second bandwidth is part of a first bandwidth for carrying sensing signals; receiving a seventh signal, the seventh signal including an echo signal of the first signal, or the seventh signal including an echo signal of a fifth signal, or the seventh signal being the fifth signal, wherein the first signal is carried in the first bandwidth, the first signal is used to determine information about a sensing target, the fifth signal is carried in the second bandwidth, and the fifth signal is used for sensing and / or communication.

[0030] Alternatively, the method may include: determining a first bandwidth and a second bandwidth, the first bandwidth being used to carry communication signals and the second bandwidth being used to carry sensing signals, wherein the second bandwidth is part of the first bandwidth; receiving a seventh signal, the seventh signal including an echo signal of the first signal, or the seventh signal including an echo signal of a fifth signal, or the seventh signal being the fifth signal, wherein the first signal is carried in the first bandwidth, the first signal being used to determine information about a sensing target, the fifth signal being carried in the second bandwidth, and the fifth signal being used for sensing and / or communication.

[0031] In one possible implementation, the first bandwidth may include a first frequency domain resource used to carry the first signal.

[0032] In one possible implementation, the second bandwidth may include a first sub-frequency domain resource, which is used to carry the fifth signal, and the first frequency domain resource includes the first sub-frequency domain resource.

[0033] In one possible implementation, the first bandwidth may include a first frequency domain resource for carrying the first signal, and the second bandwidth may include a first sub-frequency domain resource for carrying the fifth signal, wherein the first frequency domain resource includes the first sub-frequency domain resource.

[0034] In one possible implementation, the fifth signal can be the second signal. Correspondingly, the seventh signal can be the fourth signal.

[0035] Based on any one of the first to fourth aspects, in one possible implementation, the second signal may be a sub-signal of the first signal, or the first signal may include the second signal.

[0036] Through the above implementation, the first device transmits a first signal, which can be used solely for communication, or a portion of the first signal (i.e., the second signal) can be used for both communication and sensing. In other words, the first device can transmit one signal (i.e., the first signal) but implement two functions (communication and sensing). The sensing function is implemented based on the first signal, while the communication function is implemented based on a portion of the first signal (i.e., the second signal). This saves signaling and resource overhead and helps increase spectrum efficiency.

[0037] Based on any one of the first to fourth aspects, in one possible implementation, the first signal may be carried on a first time unit, and the second signal may be carried on the first time unit. In other words, the time units carrying the first signal and the second signal are the same or partially overlap. For example, the first signal occupies resource #1, and the second signal occupies resource #2. Resources #1 and #2 include the first time unit in the time domain, resource #1 includes a first frequency domain resource in the frequency domain, and resource #2 includes a first sub-frequency domain resource in the frequency domain, and the first frequency domain resource includes the first sub-frequency domain resource.

[0038] With the above implementation, the time units carrying the first signal and the second signal are the same or partially overlap, and the frequency domain unit carrying the first signal includes the frequency domain unit carrying the second signal. In this way, the first device can achieve two functions by sending a signal (the first signal): communication and sensing. The sensing function is implemented based on the first signal, and the communication function is implemented based on a part of the first signal (i.e., the second signal). This can save signaling overhead and improve spectral efficiency.

[0039] Based on any one of the first to fourth aspects, in one possible implementation, the information carried by the second signal may be part or all of the information carried by the first signal; and / or, the second signal may be part or all of the signal in the first signal. Optionally, the information carried by the second signal being part or all of the information carried by the first signal can be understood as: the payload carried by the second signal being part or all of the payload carried by the first signal; or as: the second sequence generating the second signal being part or all of the sequence in the first sequence generating the first signal; or as: the original information bits corresponding to the second signal being part or all of the original information bits corresponding to the first signal. Optionally, the second signal being part or all of the signal in the first signal can be understood as: the waveform of the second signal being part or all of the waveform of the first signal.

[0040] With the above implementation, the first device does not need to generate the first signal and the second signal separately, such as the generated first signal including the information carried by the second signal. Correspondingly, the signal receiving end (such as the second device) does not need to decode the first signal and the second signal separately, such as the decoded first signal including the information carried by the second signal.

[0041] Based on any one of the first to fourth aspects, in one possible implementation, the bandwidth of the first frequency domain resource can be M times the bandwidth of the first sub-frequency domain resource, where M is a positive integer. Optionally, the bandwidth of the first frequency domain resource can be understood as: the bandwidth occupied by the first signal, or the bandwidth including the first frequency domain resource, or a continuous frequency domain resource including the first frequency domain resource, or the bandwidth to which the first frequency domain resource belongs. For example, the first frequency domain resource can be part or all of the frequency domain resources within the bandwidth of the first frequency domain resource. Optionally, the bandwidth of the first sub-frequency domain resource can be understood as: the bandwidth occupied by the second signal, or the bandwidth including the first sub-frequency domain resource, or a continuous frequency domain resource including the first sub-frequency domain resource, or the bandwidth to which the first sub-frequency domain belongs. For example, the first sub-frequency domain resource can be part or all of the frequency domain resources within the bandwidth of the first sub-frequency domain resource.

[0042] Through the above implementation, the first device maps the first signal onto the first frequency domain resource. The design of an integer multiple (i.e., M times) can simplify the mapping process of the first device. Correspondingly, it can also simplify the decoding process of the signal receiving end (such as the second device).

[0043] Based on any one of the first to fourth aspects, in one possible implementation, the first frequency domain resource and the first sub-frequency domain resource satisfy any one of the following: the lowest frequency in the first frequency domain resource is the same as the lowest frequency in the first sub-frequency domain resource; the highest frequency in the first frequency domain resource is the same as the highest frequency in the first sub-frequency domain resource; or, the center frequency point of the first frequency domain resource is the same as the center frequency point of the first sub-frequency domain resource. Optionally, the lowest frequency domain can be replaced with: the frequency domain unit corresponding to the lowest index, or the frequency domain unit corresponding to the lowest index. Optionally, the highest frequency can be replaced with: the frequency domain unit corresponding to the highest index, or the frequency domain unit corresponding to the highest index.

[0044] In the above implementation, the lowest frequency in the first frequency domain resource is the same as the lowest frequency in the first sub-frequency domain resource, and / or the highest frequency in the first frequency domain resource is the same as the highest frequency in the first sub-frequency domain resource, which helps to reduce the complexity of signal mapping. The center frequency point of the first frequency domain resource is the same as the center frequency point of the first sub-frequency domain resource, which helps to reduce the complexity of blind detection at the signal receiver.

[0045] Based on any one of the first to fourth aspects, in one possible implementation, the first frequency domain resource includes N first frequency domain units, and the first sub-frequency domain resource includes H second frequency domain units. The first frequency domain units and the second frequency domain units may be the same or different, and N and H are both positive integers. The first frequency domain units may, for example, be resource elements, resource blocks, channels, sub-channels, control channel elements, carriers, or bands. The second frequency domain units may, for example, be resource elements, resource blocks, channels, sub-channels, control channel elements, carriers, or bands.

[0046] Through the above implementation, the first frequency domain resources and the first sub-frequency domain resources can adopt the same frequency domain granularity, which can reduce the blind detection complexity of the signal receiver; or, the first frequency domain resources and the first sub-frequency domain resources can adopt different frequency domain granularities, which can meet the different functional requirements of the first signal and the second signal.

[0047] Based on any one of the first to fourth aspects, in one possible implementation, the first signal and the second signal may satisfy at least one of the following: the comb tooth values ​​of the first signal and the second signal are the same; or, the comb tooth offset values ​​of the first signal and the second signal are the same. Optionally, the same comb tooth values ​​of the first signal and the second signal can be replaced by: the comb tooth value of the mapped first signal being the same as the comb tooth value of the mapped second signal, or the frequency domain interval of the mapped first signal being the same as the frequency domain interval of the mapped second signal, or the comb tooth values ​​of the mapped first signal being the same as the comb tooth values ​​of the mapped second signal, or the frequency domain interval of the mapped first signal being the same as the frequency domain interval of the mapped second signal. Optionally, the same comb tooth offset values ​​of the first signal and the second signal can be replaced by: the comb tooth offset values ​​of the mapped first signal being the same as the comb tooth offset values ​​of the mapped second signal, or the comb tooth offset values ​​of the mapped first signal being the same as the comb tooth offset values ​​of the mapped second signal.

[0048] With the above implementation, the comb tooth values ​​for mapping the first signal and mapping the second signal are the same, meaning that the first signal and the second signal can be mapped to the same comb tooth, or the first signal and the second signal can be mapped to two orthogonal comb teeth in the frequency domain, which reduces the mapping complexity of the first signal and the second signal. The same comb tooth offset values ​​for mapping the first signal and mapping the second signal also mean that the first signal and the second signal can be mapped to the same comb tooth, further reducing the mapping complexity of the first signal and the second signal.

[0049] Based on any one of the first to fourth aspects, in one possible implementation, the comb tooth value includes I first frequency domain units, or the comb tooth value includes J second frequency domain units; and / or, the comb tooth offset value includes P first frequency domain units, or the comb tooth offset value includes Q second frequency domain units; wherein I, J, P, and Q are all positive integers.

[0050] Through the above implementation, the frequency domain granularity of the comb tooth values ​​mapping the first signal and the second signal can be the same as the frequency domain granularity of the first frequency domain resource, or the same as the frequency domain granularity of the first sub-frequency domain resource; and / or, the frequency domain granularity of the comb tooth offset values ​​mapping the first signal and the second signal can be the same as the frequency domain granularity of the first frequency domain resource, or the same as the frequency domain granularity of the first sub-frequency domain resource, which can adapt to different communication scenarios and meet different communication needs.

[0051] Based on any one of the first to fourth aspects, in one possible implementation, the first signal is mapped from the lowest frequency of the first sub-frequency domain resource to the highest frequency of the first frequency domain resource, and then from the lowest frequency of the first frequency domain resource to the lowest frequency of the first sub-frequency domain resource; or, the first signal is mapped from the lowest frequency of the first frequency domain resource to the highest frequency of the first frequency domain resource.

[0052] Through the above implementation methods, there are multiple mapping methods for the first signal, which can be adapted to different communication scenarios. Mapping the first signal from the lowest frequency of the first sub-frequency domain resource to the highest frequency of the first frequency domain resource, and then from the lowest frequency of the first frequency domain resource back to the lowest frequency of the first sub-frequency domain resource, allows the first signal to be preferentially mapped to the first sub-frequency domain resource within the first frequency domain resource, and then to the remaining frequency domain resources. This prioritizes the mapping of communication signals, which is beneficial for improving communication performance. Mapping the first signal from the lowest frequency of the first frequency domain resource to the highest frequency of the first frequency domain resource is simple and reduces mapping complexity.

[0053] Based on any one of the first to fourth aspects, in one possible implementation, the first signal is generated by a first sequence, and the second signal is generated by a second sequence, wherein: the second sequence is part or all of the first sequence; or, the first sequence is a repeating sequence of the second sequence.

[0054] In the above implementation, the first signal is generated by the first sequence and the second signal is generated by the second sequence. The first sequence includes the second sequence, so the frequency domain resources mapped by the first sequence may include the frequency domain resources mapped by the second sequence. That is, it indirectly indicates that the frequency domain resources occupied by the first signal include the frequency domain resources occupied by the second sequence, thereby realizing the design of sensing resources and communication resources.

[0055] Based on any one of the first to fourth aspects, in one possible implementation, the second sequence may consist of K elements, where K is a positive integer; the second sequence is a partial sequence of the first sequence, and may include: the second sequence consisting of the first K elements of the first sequence; or, the second sequence consisting of K consecutive elements of the first sequence; or, the second sequence consisting of the last K elements of the first sequence; or, the second sequence consisting of any K elements of the first sequence.

[0056] Based on any one of the first to fourth aspects, in one possible implementation, the first signal may be generated by a first sequence, and the second signal may be generated by a second sequence, wherein the length of the first sequence is G times the length of the second sequence, and G is a positive integer.

[0057] Based on any one of the first to fourth aspects, in one possible implementation, the first frequency domain resource belongs to a first bandwidth, the first sub-frequency domain resource belongs to a second bandwidth, wherein the first bandwidth is used to carry sensing signals, the second bandwidth is used to carry sensing signals and / or communication signals, and the second bandwidth is part or all of the bandwidth in the first bandwidth.

[0058] Through the above implementation, the sensing signal is carried by a first bandwidth, and the communication signal is carried by a second bandwidth. The first bandwidth includes the second bandwidth, thus realizing the design of sensing and communication resources. Furthermore, the bandwidth used for sensing (i.e., the first bandwidth) is not limited to the bandwidth used for communication (i.e., the second bandwidth). This adapts to scenarios where the processing methods for sensing signals differ from those for communication signals; for example, the sensing signal may not require demodulation, but the communication signal does. Further, the first bandwidth including the second bandwidth means that the second bandwidth can transmit both sensing and communication signals, saving signaling overhead and improving spectral efficiency. The first bandwidth including the second bandwidth, and the first bandwidth being greater than the second bandwidth, means that sensing signals can be transmitted outside the communication bandwidth, decoupling the bandwidth used for sensing from the bandwidth used for communication, which is beneficial for improving sensing performance.

[0059] Based on any one of the first to fourth aspects, in one possible implementation, the above method may further include: sending a first message, or receiving a first message, wherein the first message is used to indicate the first bandwidth, and / or the first message is used to indicate the second bandwidth; wherein the first message is carried in the second bandwidth, or the first message is carried only in the second bandwidth, or the first message is not carried in frequency domain resources other than the second bandwidth.

[0060] Through the above implementation method, the configuration of the first bandwidth and the second bandwidth can be achieved through the first message. The same detection method and the same format can be used for decoding, reducing the complexity of blind detection and simplifying the implementation. Furthermore, the first message is carried within the second bandwidth, and the frequency domain range of the second bandwidth can be smaller than that of the first bandwidth. This allows for the detection of the configuration messages (i.e., the first message) of the first and second bandwidths within a smaller frequency domain range (i.e., within the second bandwidth).

[0061] Based on any one of the first to fourth aspects, in one possible implementation, the first message includes a first field, which is used to indicate the first bandwidth and / or indicate the second bandwidth; or, the first message includes a second field and a third field, wherein the value of the third field includes a first value and / or a second value, wherein the first value is used to indicate that the second field indicates the first bandwidth, and the second value is used to indicate that the second field indicates the second bandwidth.

[0062] The first message can be implemented in various ways, adaptable to different communication scenarios. For example, the first message can use a unified downlink control information format to indicate the first bandwidth and the second bandwidth respectively, or the value of the third field can be used to distinguish whether the second field indicates the first bandwidth or the second bandwidth.

[0063] Based on any one of the first to fourth aspects, in one possible implementation, the above method may further include: sending a second message, or receiving a second message, wherein the second message is used to indicate the first frequency domain resource, and / or the second message is used to indicate the first sub-frequency domain resource; wherein the second message is carried in the second bandwidth, or the second message is carried only in the second bandwidth, or the second message is not carried in frequency domain resources other than the second bandwidth.

[0064] Through the above implementation, the configuration of the first frequency domain resources and the first sub-frequency domain resources can be achieved through the second message. The same detection method and format can be used for decoding, reducing the complexity of blind detection and simplifying the implementation. Furthermore, the second message is carried within the second bandwidth, whose frequency domain range can be smaller than that of the first bandwidth. This allows for the detection of the configuration messages (i.e., the first message) of the first frequency domain resources and the first sub-frequency domain resources within a smaller frequency domain range (i.e., within the second bandwidth).

[0065] Based on any one of the first to fourth aspects, in one possible implementation, the second message includes a fourth field, which is used to indicate the first frequency domain resource and / or indicate the first sub-frequency domain resource; or, the second message includes a fifth field and a sixth field, the value of the sixth field including a third value and / or a fourth value, wherein the third value is used to indicate that the fifth field indicates the first frequency domain resource, and the fourth value is used to indicate that the fifth field indicates the first sub-frequency domain resource; or, the second message includes a fifth field and a seventh field, the value of the seventh field including at least one of a fifth value, a sixth value, and a seventh value, wherein the fifth value is used to indicate that the fifth field indicates a frequency domain resource for carrying the first signal excluding the second signal, the sixth value is used to indicate that the fifth field indicates a frequency domain resource for carrying the second signal, and the seventh value is used to indicate that the fifth field indicates a frequency domain resource for carrying the first signal including the second signal.

[0066] The second message can be implemented in various ways, adaptable to different communication scenarios. For example, the second message can use a unified downlink control information format to indicate the first frequency domain resource and the first sub-frequency domain resource respectively, or the value of the sixth field (or the value of the seventh field) can be used to distinguish whether the fifth field indicates the first frequency domain resource or the first sub-frequency domain resource.

[0067] Based on any one of the first to fourth aspects, in one possible implementation, the first bandwidth is a first bandwidth part (BWP), the second bandwidth is a second BWP, and the second BWP is part or all of the bandwidth in the first BWP; or, the first bandwidth is a first BWP, and part or all of the bandwidth in the first BWP is the second bandwidth; or, the second bandwidth is a second BWP, and the second BWP is part or all of the bandwidth in the first bandwidth.

[0068] Through the above implementation, the first device and / or the second device can maintain two or one BWP, adapting to different communication scenarios. For example, if the first bandwidth is the first BWP and the second bandwidth is the second BWP, the first device and / or the second device need to maintain two BWPs, namely the first BWP and the second BWP. Alternatively, if the first bandwidth is the first BWP, and part or all of the bandwidth of the first BWP is the second bandwidth, the first device and / or the second device need to maintain one BWP, namely the first BWP, thus limiting the transmission of communication signals to a narrower frequency range than the first BWP, simplifying the complexity of detection and decoding. Yet another example: if the second bandwidth is the second BWP, and the second BWP is part or all of the first bandwidth, the first device and / or the second device need to maintain one BWP, namely the second BWP, allowing the sensing signal to be transmitted outside a wider frequency range than the second BWP, which is beneficial for improving sensing performance.

[0069] Based on any one of the first to fourth aspects, in one possible implementation, the first bandwidth may satisfy at least one of the following: the first bandwidth is greater than or equal to the bandwidth corresponding to the control resource set with an index value of 0; the first bandwidth is greater than or equal to the initial bandwidth; or, the first bandwidth is greater than or equal to the default bandwidth. Optionally, the initial bandwidth may be predefined or preconfigured, and this application does not limit this. The initial bandwidth may, for example, be the initial communication bandwidth (such as the initial communication BWP), or the initial sensing bandwidth (such as the initial sensing BWP), or a predefined initial bandwidth in a future communication system (or sensing system), and this application does not limit this. Optionally, the default bandwidth may be predefined or preconfigured, and this application does not limit this. The default bandwidth may, for example, be the default communication bandwidth (such as the default communication BWP), or the default sensing bandwidth (such as the default sensing BWP), or a predefined default bandwidth in a future communication system (or sensing system), and this application does not limit this. Optionally, the default bandwidth may be the initial bandwidth. Optionally, the first bandwidth being greater than or equal to the bandwidth corresponding to the control resource set with index value 0 can be replaced by: the frequency domain range of the first bandwidth including the frequency domain range of the bandwidth corresponding to the control resource set with index value 0. Optionally, the first bandwidth being greater than or equal to the initial bandwidth can be replaced by: the frequency domain range of the first bandwidth including the frequency domain range of the initial bandwidth. Optionally, the first bandwidth being greater than or equal to the default bandwidth can be replaced by: the frequency domain range of the first bandwidth including the frequency domain range of the default bandwidth.

[0070] Through the above implementation method, the first bandwidth is related to at least one of the bandwidth, initial bandwidth, or default bandwidth corresponding to the control resource set with an index value of 0, which can ensure the detection and decoding process of configuration messages such as the first message and the second message.

[0071] Based on any one of the first to fourth aspects, in one possible implementation, the first bandwidth includes the second bandwidth, which may include: the second bandwidth being a continuous frequency domain resource within the first bandwidth.

[0072] With the above implementation, the second bandwidth is a continuous frequency domain resource. In other words, the frequency domain resource carrying the second signal (or the fifth signal) is a continuous frequency domain resource, which can simplify the mapping, decoding and other processes.

[0073] Based on any one of the first to fourth aspects, in one possible implementation, the above method may further include: stopping the timing of a first inactive timer during or while performing perception, wherein the first inactive timer includes an inactive timer corresponding to the first bandwidth and / or an inactive timer corresponding to the second bandwidth.

[0074] The above implementation stops the timing of the first inactive timer during or while performing sensing. This avoids switching to the initial or default bandwidth during or while performing sensing, allowing the sensing signal to be transmitted in the active bandwidth. Typically, the active bandwidth is greater than the initial or default bandwidth, and the wider the bandwidth, the better the sensing performance, thereby improving sensing performance, such as improving ranging accuracy.

[0075] Fifthly, this application provides a sensing device that can be used to perform the methods described in the first or third aspect and any possible implementation thereof. This sensing device may also be referred to as a communication-sensing integrated device, or a sensing-communication integrated device. The sensing device may, for example, be a first device. The sensing device may include modules, units, or means corresponding to the methods described in the first or third aspect and any possible implementation thereof. These modules, units, or means may be implemented in hardware, software, or by hardware executing corresponding software.

[0076] In one possible implementation, the sensing device may include a baseband device and a radio frequency device.

[0077] In another possible implementation, the sensing device may include a processing module (sometimes also called a processing unit) and a transceiver module (sometimes also called a transceiver unit).

The transmitting module and the receiving module may be the same functional module, referred to as the transceiver module, which performs both transmitting and receiving functions; alternatively, the transmitting module and the receiving module may be different functional modules, with "transceiver module" being a collective term for these functional modules.

These modules, units, or means may be implemented in hardware, software, or by hardware executing corresponding software implementations. The hardware or software includes one or more modules or units corresponding to the aforementioned functions.

[0079] In one possible implementation, the sensing device may include a baseband device and a radio frequency device.

[0080] In another possible implementation, the sensing device may include a processing module (sometimes also called a processing unit) and a transceiver module (sometimes also called a transceiver unit). The transceiver module is capable of both transmitting and receiving functions. When the transceiver module performs the transmitting function, it may be called a transmitting module (sometimes also called a transmitting unit), and when it performs the receiving function, it may be called a receiving module (sometimes also called a receiving unit). The transmitting module and the receiving module may be the same functional module, referred to as the transceiver module, which performs both transmitting and receiving functions; alternatively, the transmitting module and the receiving module may be different functional modules, with "transceiver module" being a collective term for these functional modules.

[0103] The relevant terms used in the embodiments of this application will be explained below. It should be noted that these explanations are for the purpose of making the embodiments of this application easier to understand, and should not be regarded as a limitation on the scope of protection claimed by this application.

[0104] I. Sensing, sensing signals, communication signals, echo signals, communication-sensing fusion signals, and targets:

[0105] 1) Perception can also be replaced with: detection, sensing process, sensing operation, sensing detection, detection processing, executing perception, running perception, executing perception business, or running perception business, etc. It should be understood that perception can be a business (or task), or it may not be a business (or task).

[0106] Perception can be understood as a technology capable of acquiring information about the characteristics of the environment and / or objects within it. This information includes, but is not limited to, shape, size, orientation, speed, position, distance between objects, or relative motion. The working principle of perception is as follows: the transmitting end sends a perception signal, and the receiving end receives the perception signal (also called the echo signal) after it has passed through the sensing target (or through scattering, diffraction, or diffusion). Based on the received perception signal, the sensing result is obtained, such as speed, distance, shape, and size.

[0107] 2) Sensing signal: A signal used to sense (or detect) a target (or object) or its surrounding environment. For example, a sensing signal can be a signal transmitted over an air interface and used to sense a target or its surrounding environment. Optionally, a sensing signal can also be called a signal used for sensing, a sensing reference signal, a reference signal used for sensing, a detection signal, a linear frequency modulated signal, a radar signal, a radar sensing signal, a radar detection signal, or an environmental sensing signal, etc. Optionally, a sensing signal can be a pulse signal or a signal in a wireless communication system (or sensing system).

[0108] As an example, the sensing signal can be any of the following: channel state information-reference signal (CSI-RS), synchronization signal block (SSB), positioning reference signal (PRS), sounding reference signal (SRS), sensing reference signal, demodulation reference signal (DMRS), physical random access channel (PRACH), or service request (SR) signal. The SRS can be a multi-input multi-output (MIMO) SRS or a positioning SRS, etc.

[0109] For example, the frequency domain resources (such as the first frequency domain resource or the first sub-frequency domain resource hereinafter) and bandwidths (such as the first bandwidth or the second bandwidth hereinafter) involved in this application can be understood as frequency domain resources carrying sensing signals. These frequency domain resources carrying sensing signals can be, for example, any one of CSI-RS resources, SSB resources, PRS resources, SRS resources, sensing reference signal resources, DMRS resources, PRACH resources (e.g., RACH occasion), or SR resources.

[0110] The sensed signal can propagate via the path of "sensing transmitter - sensing target - sensing receiver", or via the path of "sensing transmitter - sensing receiver", or via the path of "sensing transmitter - interference / environment - sensing receiver". In other words, the sensed signal can be a single path or a combination of the above paths, and the sensing receiver receives the sum of the signals from the above paths.

[0111] It should be understood that the term "sensing transmitter" in the embodiments of this application can be used interchangeably with the terms "transmitter" and "transmitter of sensing signal". Similarly, the term "sensing receiver" in the embodiments of this application can be used interchangeably with the terms "receiver" and "receiver of sensing signal".

[0112] Therefore, in this embodiment, the transmitted sensing signal can be called sensing signal A, and the received sensing signal can be called sensing signal B. In fact, sensing signal A and sensing signal B are the same signal (e.g., both are referred to as sensing signals). During sensing, changes in sensing signal B compared to sensing signal A include changes caused by reflection, scattering, or diffusion from the sensing target. For example, these changes include variations in the time and / or frequency domains of the sensing signal, and further, variations in the amplitude and / or phase of the sensing signal. These changes reflect, to some extent, the information of the sensing target.

[0113] 3) Communication signals can be signals transmitted between communication devices for communication purposes. Optionally, these communication signals can carry communication data information, communication control information, or be used for communication measurement, without limitation. For example, communication signals may include signals transmitted between network devices and terminal devices. Communication signals may be carried, for example, on a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), a physical downlink control channel (PDCCH), a physical uplink control channel (PUCCH), or a physical random access channel (PRACH); or, for example, on SR, CSI-RS, SRS, or DMRS.

[0114] 4) Echo signals can be understood as signals generated by the reflection (scattering, diffraction, or diffusion) of a sensing signal by the target. Echo signals, or a combination of echo and sensing signals, can reflect target parameters. For example, the time delay of the echo signal relative to the transmitted sensing signal can reflect the target's distance from the transmitter. For example, the Doppler shift of the echo signal relative to the sensing signal can reflect the target's velocity. For example, the phase difference between multiple echo signals can reflect the target's angle.

[0115] 5) Communication-sensing fusion signal can be understood as a signal used for both communication and sensing, or as a signal that multiplexes a communication signal for sensing. Optionally, the communication-sensing fusion signal can also be called a synsensory-sensing fusion signal, a synsensory signal, or a synsensory-integrated signal, etc. Wherein, the synsensory-sensing fusion signal is used for communication, which can be understood as the signal carrying the communication data or communication reference signal sequence that needs to be transmitted between communication devices. Wherein the synsensory-sensing fusion signal is used for sensing, which can be understood as the synsensory-sensing fusion signal being used to sense (or detect) a target.

[0116] 6) The target can be any tangible object in the environment capable of reflecting electromagnetic waves. In this application, the characteristics of the target can be deduced through sensing signals. For example, mountains, forests, roads, or buildings, and can also include mobile objects such as vehicles, drones, pedestrians, automated equipment, and terminal devices. Optionally, the target can also be referred to as a sensed target, a detected target, a sensed object, a sensed device, a sensing target, a detection target, a sensed object, or a detection object, etc., and the embodiments of this application do not limit this.

[0117] For electromagnetic sensing, a target can generally be modeled as at least one scattering point (or scattering center, scatterer, etc.), and the process of a target reflecting (or scattering, or diffracting, or scattering, etc.) electromagnetic waves can be equivalent to the process of at least one scattering point reflecting (or scattering, or diffracting, or scattering, etc.). For example, for a point-like target, the target can be modeled as a single scattering point. For example, for an extended target, the target can be modeled as multiple scattering points. Accordingly, the target in this application can be understood as a single scattering point, or it can be understood as multiple scattering points. In the following text, unless otherwise specified, the target can be understood as a single scattering point.

[0118] II. Perception Mode:

[0119] In terms of sensing, depending on the sender and receiver of the sensing signal, the sensing mode can be divided into two modes: single-station sensing and dual-station sensing.

[0120] Single-site sensing mode refers to a mode where the device transmitting sensing signal A and the device receiving sensing signal B are the same device; or, the transmitter of sensing signal A and the receiver of sensing signal B are located in the same device. As shown in Figure 1A, both the device transmitting sensing signal A and the device receiving sensing signal B are device 1. Optionally, single-site sensing mode can be called self-transmitting and self-receiving mode, single-base sensing mode, or mono-static sensing mode, etc. Figure 1A uses a vehicle as an example. Sensing signal B includes the echo signal of sensing signal A reflected by the target.

[0121] In Figure 1A, device 1 can be a network device or a terminal device. For example, in Figure 1A, device 1 is a network device. In single-site sensing mode, the network device sends sensing signal A and receives sensing signal B to perform environmental sensing. Optionally, since device 1 is a network device, the sensing mode shown in Figure 1A can also be called the network device single-site sensing mode. As another example, in Figure 1A, device 1 is a terminal device. In single-site sensing mode, the terminal device sends sensing signal A and receives the sensing signal B to perform environmental sensing. Optionally, since device 1 is a terminal device, the sensing mode shown in Figure 1A can also be called the terminal device single-site sensing mode.

[0122] Dual-station sensing mode refers to a mode where the device transmitting sensing signal A and the device receiving sensing signal B are different devices; or, the transmitter transmitting sensing signal A and the receiver receiving sensing signal B are located in different devices. As shown in Figure 1B, the device transmitting sensing signal A is device 2, and the device receiving sensing signal B is device 3. Optionally, dual-station sensing mode can also be called A-transmit B-receive mode, self-transmit and other-receive mode, dual-base sensing mode, or bi-static sensing mode, etc. Figure 1B uses a vehicle as an example.

[0123] In Figure 1B, device 2 can be a network device and device 3 can be a terminal device (referred to as a network device-terminal device dual-site sensing mode); or device 2 can be a terminal device and device 3 can be a network device (referred to as a terminal device-network device dual-site sensing mode); or devices 2 and 3 can both be different network devices (referred to as network device A-network device B dual-site sensing mode); or devices 2 and 3 can both be terminal devices (referred to as terminal device A-terminal device B dual-site sensing mode). For example, in Figure 1B, device 2 is a network device and device 3 is a terminal device. In the dual-site sensing mode, the network device sends sensing signal A, and the terminal device receives the sensing signal B to perform environmental sensing. As another example, in Figure 1B, device 2 is a terminal device and device 3 is a network device. In the dual-site sensing mode, the terminal device sends sensing signal A, and the network device receives the sensing signal B to perform environmental sensing. For example, in Figure 1B, device 2 is network device 1 and device 3 is network device 2. In the dual-site sensing mode, network device 1 sends sensing signal A and network device 2 receives sensing signal B to perform environmental sensing. For example, in Figure 1B, device 2 is terminal device 1 and device 3 is terminal device 2. In the dual-site sensing mode, terminal device 1 sends sensing signal A and terminal device 2 receives sensing signal B to perform environmental sensing.

[0124] III. Resources:

[0125] Resources may include at least one of the following: time-domain resources, frequency-domain resources, code-domain resources, spatial-domain resources, or sequence resources, etc. In the embodiments of this application, resources may include two dimensions: time domain and frequency domain.

[0126] The unit of time-domain resources can be called a time-domain unit or a time unit, etc. A time unit can be, for example, at least one symbol, at least one orthogonal frequency division multiplexing (OFDM) symbol, at least one slot, at least one sensing slot, at least one mini-slot, at least one partial slot, at least one sub-frame, at least one frame, or at least one radio frame, etc.

[0127] The unit of a frequency domain resource can be called a frequency domain unit or frequency cell. A frequency domain unit can be, for example, a resource element (RE), a resource block (RB), an RB set, a channel, a sub-channel, a control channel element (CCE), an interlace, a comb, a resource pool, a bandwidth part (BWP), a bandwidth part group (BWPG), a carrier, a carrier group, or a band. Optionally, a resource block can include a physical resource block (PRB) and / or a virtual resource block (VRB).

[0128] The time and frequency domain units mentioned above can be combined arbitrarily. For example, a resource unit can be a time-frequency resource unit where the time unit is a symbol and the frequency domain unit is a resource element. As another example, a resource unit can be a time-frequency resource unit where the time unit is a symbol and the frequency domain unit is a resource block.

[0129] Alternatively, the time unit for transmitting the sensing signal can also be called the transmission occasion of the sensing signal; the two can be used interchangeably.

[0130] IV. Terminal Equipment:

[0131] A terminal device is a device with wireless transceiver capabilities. It can be a fixed device, mobile device, handheld device (e.g., mobile phone), wearable device, in-vehicle device, or a wireless device (e.g., communication module, modem, or chip system) built into the aforementioned devices. The terminal device is used to connect people, objects, and machines, and can be widely used in various scenarios, including but not limited to: sensing scenarios, cellular communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-to-machine / machine-type (M2M / MTC) communication, Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, self-driving, remote medical care, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, drones, robots, and terminal devices in indoor commercial scenarios (e.g., mobile phone screen mirroring, file sharing, and video transmission from mobile phone to VR glasses). When the terminal equipment is applied to V2X, it can also be called a V2X device, such as a smart car, digital car, unmanned car, driverless car, pilotless car, or automobile, self-driving car, or autonomous car, pure electric vehicle (EV), hybrid electric vehicle (HEV), range-extended electric vehicle (REEV), plug-in hybrid electric vehicle (PHEV), new energy vehicle, or roadside unit (RSU). The terminal equipment can also be a device used in D2D communication, such as an electricity meter or water meter.

[0132] Furthermore, in this embodiment, the terminal device can also be a terminal device in an IoT system. IoT is an important component of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection.

[0133] The various terminal devices described above, if located in a vehicle (e.g., placed inside or installed inside a vehicle), can all be considered in-vehicle terminal devices, also known as on-board units (OBUs). The terminal device of this application can also be an in-vehicle module, in-vehicle component, in-vehicle chip, or in-vehicle unit built into a vehicle as one or more components or units. The vehicle can implement the methods of this application through the built-in in-vehicle module, in-vehicle component, in-vehicle chip, or in-vehicle unit.

[0134] The terminal equipment may sometimes be referred to as user equipment (UE), terminal, access station, UE station, remote station, wireless communication equipment, or user device, etc.

[0135] In this application embodiment, the device for implementing the terminal device function can be the terminal device itself, or it can be a device capable of supporting the terminal device in implementing the function, such as a chip system. This device can be installed in the terminal device. In the technical solutions provided in this application embodiment, the terminal device is used as an example to describe the technical solutions provided in this application embodiment. Furthermore, for ease of description, the terminal device in this application embodiment is described using a UE as an example.

[0136] V. Network Equipment:

[0137] Network equipment, including access network equipment and / or core network equipment.

[0138] 1) Core network equipment refers to the equipment in the core network that provides service support to terminals. For example, in the context of the 5th generation (5G) core network, the evolved 5G core network, or the core network of future communication systems (or sensing systems), some examples of core network equipment include: access and mobility management function (AMF) entities, session management function (SMF) entities, user plane function (UPF) entities, policy control function (PCF) entities, location management function (LMF) entities, etc., which will not be listed here. These core network devices can work independently or be combined to implement certain control functions; for example, AMF, SMF, and PCF can be combined into a single core network device.

[0139] Optionally, the core network equipment may also include a sensing function (SF) entity (or sensing entity). The sensing function entity can be used to sense targets, such as determining the target's location or reconstructing the target's environment, and is not limited thereto. This application does not limit the deployment of the sensing function entity. For example, the sensing function entity can be deployed in the core network or in the access network, without limitation. For example, the sensing function entity can also be a sensing server, a network management platform, or a network management device, etc. It should be understood that in future communication systems (or sensing systems), the functional entity used for sensing targets may still be called a sensing function entity, or it may have other names; this application does not limit this.

[0140] It should be noted that in this application, an entity can also be referred to as a network element or a functional entity. For example, a sensing entity can also be referred to as a sensing network element, a sensing functional entity, or a sensing functional network element.

[0141] 2) Access network equipment is a network-side device with wireless transceiver capabilities. For example, a device that provides wireless communication capabilities to terminal devices in a radio access network (RAN) is called an RAN device or RAN node.

[0142] As an example, the access network equipment includes, but is not limited to, base stations (base transceiver stations, BTS, Node B, evolved Node B (eNodeB) / eNB, or next-generation Node B (gNodeB) / gNB), transmission reception points (TRPs), base stations evolved under the 3rd generation partnership project (3GPP), access nodes in Wi-Fi systems, wireless relay nodes, wireless backhaul nodes, etc. The base stations can be: macro base stations, micro base stations, pico base stations, small cells, relay stations, etc. Multiple base stations can support networks using the same access technology or networks using different access technologies. A base station can contain one or more co-located or non-co-located transmission and reception points. As another example, the access network device can also be a radio controller, centralized unit (CU), and / or distributed unit (DU) in a cloud radio access network (CRAN) scenario. Optionally, a centralized unit can also be called a control unit. As yet another example, the access network device can also be a server, etc. For example, the access network device in V2X technology can be a roadside unit (RSU). The following description uses a base station as an example to illustrate the access network device. A base station can communicate with a terminal device, or it can communicate with a terminal device through a relay station. A terminal device can communicate with multiple base stations in different access technologies.

[0143] Optionally, in the CU-DU architecture, the access network equipment may include one or more logical units (or logical network elements) such as CU, DU, or radio unit (RU). This application does not limit the number of CU, DU, and RU. CU and DU can be configured separately or included in the same network element, such as in a baseband unit (BBU). RU may be included in radio equipment or radio units, such as in a remote radio unit (RRU), active antenna unit (AAU), or remote radio head (RRH). For example, the CU can perform the functions of the radio resource control (RRC) protocol and packet data convergence protocol (PDCP) of the base station, and can also perform the functions of the service data adaptation protocol (SDAP). For example, the DU can perform the functions of the radio link control layer and medium access control (MAC) layer of the base station, and can also perform some or all of the physical layer functions. For a detailed description of each of the above protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP).

[0144] Optionally, the CU may include a CU-control plane (CP) and / or a CU-user plane (UP). For example, the CU-CP is a logical node carrying the RRC layer and the PDCP-control plane (PDCP-C) layer, and can be used to implement the control plane functions of the CU. For instance, the CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be, for example, sensing network elements, AMFs, etc., and are not limited. For example, the CU-UP is a logical node carrying the SDAP layer and the PDCP-user plane (PDCP-U) layer, and can be used to implement the user plane functions of the CU. For example, the CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements in the core network can be, for example, UPFs, etc., and are not limited.

[0145] In different systems, CU (or CU-CP and / or CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open-CU (open-CU, O-CU), DU can also be called an open-DU (open-DU, O-DU), CU-CP can also be called an open-CU-CP (open-CU-CP, O-CU-CP), CU-UP can also be called an open-CU-UP (open-CU-UP, O-CU-UP), and RU can also be called an open-RU (open-RU, O-RU). For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0146] Optionally, in various embodiments of this application, if the access network device is a distributed architecture, for example, the access network device includes CU and DU, or includes CU-CP, CU-UP and DU, then the access network device sends information to the UE, specifically the DU included in the access network device sends information to the UE; the access network device receives information from the UE, specifically the DU included in the access network device receives information from the UE; the access network device sends information to the core network device, specifically the CU (or CU-CP, or CU-UP included in the access network device) sends information to the core network device; the access network device receives information from the core network device, which may include the CU (or CU-CP, or CU-UP included in the access network device receiving information from the core network device.

[0147] In this application embodiment, the device for implementing the network device function can be a network device itself, or a device capable of supporting the network device in implementing that function, such as a chip system, which can be installed in the network device. In the technical solutions provided in this application embodiment, the example of a network device being used to implement the network device function is used to describe the technical solutions provided in this application embodiment.

[0148] In this application embodiment, "multiple" can refer to two or more. Therefore, in this application embodiment, "multiple" can also be understood as "at least two". "At least one" can be understood as one or more, such as one, two, or more. For example, "including at least one" means including one, two, or more. For example, including at least one of A, B, and C, then it could include A, B, C, A and B, A and C, B and C, or A, B, and C. "And / or" describes the association relationship between related objects. Specifically, there can be three relationships. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / ", unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0149] In the embodiments of this application, the terms "system" and "network" can be used interchangeably, and "according to" and "based on" can be used interchangeably.

[0150] The ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are generally used to distinguish different objects, and are not used to limit the order, timing, priority, or importance of multiple objects. For example, the first device and the second device involved in the embodiments of this application are used to distinguish different devices, and do not limit the order, timing, priority, or importance of these two devices.

[0151] In this application, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0152] In this application, the term "A includes B" can be understood as: B is a subset of A; or it can be understood as: B is part or all of A; or it can be understood as: A is greater than or equal to B; or it can be understood as: B is less than or equal to A. For example, bandwidth A includes bandwidth B, which can be understood as bandwidth A and bandwidth B being the same, or bandwidth B being a proper subset of bandwidth A (or bandwidth B being a part of bandwidth A). As another example, frequency domain resource A includes sub-frequency domain resource B, which can be understood as frequency domain resource A and sub-frequency domain resource B being the same, or sub-frequency domain resource B being a proper subset of frequency domain resource A (or sub-frequency domain resource B being a part of frequency domain resource A). Furthermore, the terms "A includes B" and "B belongs to A" can be used interchangeably.

[0153] In this application, "predefined" may include predefined terms, such as protocol definitions. The "predefined" can be implemented by pre-storing corresponding codes, tables, or other means of indicating relevant information in the device (e.g., including various network elements), and this application does not limit the specific implementation method.

[0154] The term "storage" or "preservation" in this application can refer to storage in one or more memory devices. These memory devices can be separately configured or integrated into an encoder, decoder, processor, or sensing device. Alternatively, some memory devices can be separately configured, while others can be integrated into the decoder, processor, or sensing device. The type of memory can be any form of storage medium, and this is not limited.

[0155] In the schematic diagrams of the accompanying drawings of this application, the dashed arrows or boxes indicate optional steps or optional modules.

[0156] In this application, "instruction" can include direct instruction, indirect instruction, explicit instruction, and implicit instruction. When describing a certain instruction information for the purpose of instructing A, it can be understood that the instruction information carries A, directly instructs A, or indirectly instructs A.

[0157] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementations, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a relationship between the other information and the information to be instructed. It can also indicate only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent. Furthermore, the information to be instructed can be sent as a whole or divided into multiple sub-information pieces, and the sending period and / or timing of these sub-information pieces can be the same or different.

[0158] In this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which can include direct transmission via the air interface or indirect transmission via the air interface from other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which can include direct reception from YY via the air interface or indirect reception from YY via the air interface from other units or modules. "Send" can also be understood as the "output" of a chip interface, and "receive" can also be understood as the "input" of a chip interface. In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, traces, or interfaces.

[0159] In this application, the words "exemplarily," "for example," "e.g.," are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as an "example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the word "example" is intended to present concepts in a concrete manner. In the embodiments of this application, "of," "corresponding, relevant," and "corresponding" may sometimes be used interchangeably, and it should be noted that their intended meanings are consistent unless their distinction is emphasized.

[0160] This application will present embodiments relating to a system comprising multiple devices, components, modules, etc. It should be understood that the system may include other unmentioned devices, components, modules, etc., or may include only some of the devices, components, or modules mentioned in the embodiments. Optionally, the terms "component" and "part" in this application can be used interchangeably.

[0161] The sensing method provided in this application can be applied to fourth-generation (4G) communication systems, such as long-term evolution (LTE) communication systems, and also to fifth-generation (5G) communication systems, such as 5G new radio (NR) communication systems, or to future communication systems. The method provided in this application can also be applied to Bluetooth systems, wireless fidelity (Wi-Fi) systems, long-range radio (LoRa) systems, or vehicle-to-everything (V2X) systems. The method provided in this application can also be applied to satellite communication systems, wherein the satellite communication system can be integrated with the aforementioned communication systems. It should be understood that the system in which the sensing method provided in this application is applied in the future may still be called a communication system, or it may also be called a sensing system, a communication-sensing integrated system, or a sensing-communication integrated system, etc., and this application does not limit this.

[0162] Figure 2 is a schematic diagram of a scenario of integrated communication and sensing. Figure 2 may include at least one access network device, and a single access network device is shown as an example in Figure 2. For example, the access network device adopts a single-site sensing mode, wherein the sensing of scatterer 3 and scatterer 5 by the access network device is a single-site sensing mode.

[0163] Optionally, Figure 2 may also include at least one UE, with multiple UEs illustrated in Figure 2. For example, UE1 and the access network device adopt a dual-site sensing mode, where UE1 is the transmitter of the sensing signal (or, sensing fusion signal) and the access network device is the receiver of the sensing signal (or, sensing fusion signal); UE3 and the access network device may also adopt a dual-site sensing mode, where the access network device is the transmitter of the sensing signal (or, sensing fusion signal) and UE3 is the receiver of the sensing signal (or, sensing fusion signal). As another example, the UE may also sample a single-site sensing mode, which is not shown in Figure 2.

[0164] In Figure 2, the access network device and UE2 are communicating and can transmit communication signals. Additionally, the access network device can send communication signals to UE4, and can also send sensing signals or fusion signals. UE4 can receive these communication signals. If the access network device sends a fusion signal, UE4 can also receive it. The access network device uses a single-site sensing mode, and can also receive the sensing signal or fusion signal.

[0165] Optionally, Figure 2 may also include core network equipment, which is not shown in Figure 2. For example, the access network equipment may send sensing result information (or sensing data, or sensing measurement data) to the core network equipment (e.g., sensing network elements, etc.) to achieve functions such as positioning; or, for example, the UE may send sensing result information (or sensing data, or sensing measurement data) to the core network equipment (e.g., sensing network elements, etc.) through the access network equipment to achieve functions such as positioning.

[0166] Figure 2 uses UE3 as an example, where UE3 is a vehicle and scatterer 3 is a human body. There are no restrictions on the type of other UEs and scatterers.

As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0169] Communication sensing technology is one of the key technologies in next-generation wireless communication networks. Currently, there are no design schemes for sensing and communication resources, making their design a pressing issue. To address this, embodiments of this application provide various sensing methods and apparatuses for designing sensing and communication resources. These various sensing methods and apparatuses can also be referred to as integrated communication sensing methods and apparatuses, or integrated sensing methods and apparatuses. The methods and apparatuses described in this application are based on the same technical concept. Since the principles by which the methods and apparatuses solve problems are similar, the implementations of the apparatus and methods can be mutually referenced, and repeated details will not be elaborated further.

[0170] This application's method embodiments relate to a first device. This first device can be a signal transmitter, used to transmit sensing signals and / or transmit communication signals. Optionally, the first device can also be used to receive sensing signals; for example, in a single-site sensing mode, the first device transmits and receives sensing signals. Exemplarily, the first device can be a terminal-side device or a network-side device.

[0171] The terminal-side device is also referred to as a terminal device or a terminal. This terminal device may be a terminal equipment or a component of a terminal equipment, such as a communication module, circuitry or chip responsible for communication functions (e.g., a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core, a chip system, or a processor, etc.) or other functional module that can be applied within the terminal equipment. This chip system or functional module can implement the functions of the terminal equipment. For example, if the chip system or functional module is located within the terminal equipment, it can also be a logic module or software that can implement all or part of the functions of the terminal equipment.

[0172] The network-side device is also referred to as a network device. This network device is, for example, a network equipment, or a component of a network equipment, such as a communication module, circuitry or chip responsible for communication functions (e.g., a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core, a chip system, or a processor, etc.) or other functional module that can be applied within the network equipment. This chip system or functional module can implement the functions of the network equipment. For example, the chip system or functional module is located within the network equipment, and can also be a logic module or software that can implement all or part of the functions of the network equipment. Optionally, the network equipment can be a non-ORAN architecture or an ORAN architecture; or, the network equipment can be a CU, DU, or RU under an ORAN architecture. The network equipment is located on the ground, for example, or it can be a non-ground device such as a satellite or an aircraft, or located on a non-ground device such as a satellite or an aircraft.

[0173] In an optional implementation, the method embodiments of this application may also involve a second device. This second device may be a signal receiver, used to receive sensing signals and / or communication signals. Exemplarily, the second device may be a terminal-side device or a network-side device; for details regarding the terminal-side device or network-side device, please refer to the description of the first device, which will not be repeated here.

[0174] For example, the first device is a terminal-side device and the second device is a network-side device; or, the first device is a network-side device and the second device is a terminal-side device; or, both the first device and the second device are terminal-side devices; or, both the first device and the second device are network-side devices.

[0175] Understandably, the first device and the second device can be the same device, or they can be two different devices. For example, if the first device transmits a sensing signal, in a single-station sensing mode, the receiving end of the sensing signal is still the first device. Or, for another example, if the first device transmits a sensing signal, in a dual-station sensing mode, the receiving end of the sensing signal is a second device, different from the first device.

[0176] In an optional implementation, the method embodiments of this application may also involve a third device. This third device may be a resource configuration terminal, capable of configuring resources for the transmission of sensing signals and / or communication signals. The third device may be, for example, a third equipment, a functional module included in a third equipment, or a larger device including a third equipment. Exemplarily, the third device may be a terminal-side device or a network-side device; for details regarding the terminal-side device or network-side device, please refer to the description of the first device, which will not be repeated here.

[0177] Understandably, the first device and the third device can be the same device, or they can be two different devices. For example, the first device may be an access network device, which may configure resources for the transmission of sensing signals and / or communication signals. Alternatively, the first and second devices may both be terminal devices, and the third device may be an access network device, which may configure resources for the transmission of sensing signals and / or communication signals of the terminal device.

[0178] Understandably, the second and third devices can be the same device or two different devices. For example, the second device may be an access network device, which may configure resources for the transmission of sensing signals and / or communication signals. Alternatively, the first and second devices may both be terminal devices, and the third device may be an access network device, which may configure resources for the transmission of sensing signals and / or communication signals.

[0179] It should be understood that this application does not limit the implementation of the first and second devices. Furthermore, please refer to the foregoing explanations of terms for access network equipment, network equipment, and terminal equipment; further elaboration is unnecessary.

[0180] The following description, in conjunction with the accompanying drawings, details several sensing methods provided in the embodiments of this application. The various embodiments of this application can be applied to the network architecture shown in Figure 2, and are not intended to limit the scope of the application.

[0181] Figure 3 is a flowchart illustrating the first sensing method provided in this embodiment. This first sensing method can also be called the first integrated communication and sensing method, or the first integrated sensing and communication method. This embodiment can realize the design of frequency domain resources for sensing signals and frequency domain resources for communication signals. As shown in Figure 3, the method includes the following:

[0182] S301: The first device determines the first frequency domain resource.

[0183] Alternatively, S301 can also be described as: the first device determines the first sub-frequency domain resource, or the first device determines both the first frequency domain resource and the first sub-frequency domain resource. Figure 3 illustrates this with the first device determining the first frequency domain resource as an example. Furthermore, S301 is an optional step, indicated by dashed lines in Figure 3.

[0184] For example, the first device may determine the first frequency domain resource during or before running sensing. It is understood that this application does not limit the timing at which the first device determines the first frequency domain resource.

[0185] The first frequency domain resource, also known as the sensing signal frequency domain resource, is not specifically named in this application. This first frequency domain resource can be used to carry a first signal. It should be understood that "the first frequency domain resource is used to carry a first signal" in this application means that the first frequency domain resource can be used to carry a first signal; in practical application, the first frequency domain resource may or may not carry a first signal. For example, if the first frequency domain resource is allocated to the first device, then the first frequency domain resource carries the first signal; if the first frequency domain resource is not allocated to the first device, then the first frequency domain resource may not carry a first signal.

[0186] The first signal can be used for sensing, or for performing sensing, or for determining information about a sensing target. The information about the sensing target may include, for example, the target's shape, size, direction, speed, position, distance, or relative motion. The first signal may be, for example, a sensing SRS, sensing CSI-RS, sensing DMRS, SSB, physical random access channel, sensing SR, or PRS, etc. This application does not limit the implementation form of the first signal. Exemplarily, the first signal is a sensing signal, or the first signal may belong to sensing signals (i.e., sensing signals include the first signal). For example, the first signal belongs to sensing signals transmitted by the first device, or the sensing signals transmitted by the first device include the first signal. Optionally, the first frequency domain resource can be understood as: frequency domain resources used to carry a certain sensing signal, or frequency domain resources configured for a certain sensing signal, etc.

[0187] The first sub-frequency domain resource, also known as the communication signal frequency domain resource or the second frequency domain resource, is not specifically named in this application. This first sub-frequency domain resource can be used to carry a second signal. It should be understood that "the first sub-frequency domain resource is used to carry a second signal" in this application means that the first sub-frequency domain resource can be used to carry a second signal. In practical application, the first sub-frequency domain resource may or may not carry a second signal. For example, if the first sub-frequency domain resource is allocated to the first device, then the first sub-frequency domain resource carries a second signal; if the first sub-frequency domain resource is not allocated to the first device, then the first sub-frequency domain resource may not carry a second signal.

[0188] In one optional implementation, the second signal can be used for communication, or the second signal can be used to perform communication, such as communication measurement, data transmission, or control signaling transmission. As an example, the second signal can be used solely for communication; for example, it can be a communication SRS, or a communication CSI-RS, a communication DMRS, a physical random access channel, or a SR, etc. Exemplarily, the second signal is a communication signal, or the second signal can belong to a communication signal (i.e., the communication signal includes the second signal). For example, the second signal belongs to a communication signal transmitted by the first device, or the communication signal transmitted by the first device includes the second signal. Optionally, the first sub-frequency domain resource can be understood as: a frequency domain resource used to carry a certain communication signal, or a frequency domain resource configured for a certain communication signal, etc.

[0189] As another example, the second signal can be used for sensing and communication, or the second signal can be used to perform sensing and communication. Exemplarily, the second signal is a sensing fusion signal, or the second signal may belong to a sensing fusion signal (i.e., the sensing fusion signal includes the second signal). The second signal may, for example, be an SRS for communication and sensing, or a CSI-RS for communication and sensing, or a DMRS for communication and sensing, or a physical random access channel for communication and sensing, or an SR for communication and sensing, etc. For example, the second signal belongs to a sensing fusion signal transmitted by the first device, or the sensing fusion signal transmitted by the first device includes the second signal. Optionally, the first sub-frequency domain resource can be understood as: frequency domain resources used to carry a certain sensing fusion signal, or frequency domain resources configured for a certain sensing fusion signal, etc.

[0190] In another alternative implementation, the second signal can be used for sensing, or the second signal can be used to perform sensing, or the second signal can be used to determine information about the sensing target. The information about the sensing target is described above and will not be repeated here. As an example, the second signal can be used solely for sensing; for example, it can be a sensing SRS, sensing CSI-RS, sensing DMRS, SSB, physical random access channel, sensing SR, or PRS, etc. Exemplarily, the second signal can belong to a sensing signal, that is, the sensing signal includes the second signal. For example, the second signal belongs to a sensing signal sent by the first device, or the sensing signal sent by the first device includes the second signal. Optionally, the first sub-frequency domain resource can be understood as: frequency domain resources used to carry a certain sensing signal, or frequency domain resources configured for a certain sensing signal, etc. As another example, the second signal can be used for both sensing and communication; its implementation is described above and will not be repeated here.

[0191] It is understood that this application does not limit the implementation form of the second signal. Furthermore, for ease of understanding, unless otherwise specified, the following description uses the second signal for communication as an example. Figure 3 illustrates this example of the second signal being used for communication.

[0192] In one optional implementation, the first frequency domain resource may include N first frequency domain units, and the first sub-frequency domain resource may include H second frequency domain units, where N and H are both positive integers. In other words, the frequency domain granularity of the first frequency domain resource is the first frequency domain unit, and the frequency domain granularity of the first sub-frequency domain resource is the second frequency domain unit. The first frequency domain unit may, for example, be a RE, RB, RB set, channel, sub-channel, control channel element, interleaving, comb, carrier, carrier group, or band, etc. The second frequency domain unit may, for example, be a RE, RB, RB set, channel, sub-channel, control channel element, interleaving, comb, carrier, carrier group, or band, etc. It should be understood that N and H can have the same or different values.

[0193] As an example, the first frequency domain unit and the second frequency domain unit can be the same, such as the first frequency domain resource and the first sub-frequency domain resource having the same frequency domain granularity. For example, the first frequency domain unit and the second frequency domain unit can both be RB, or both can be RE, etc. In this example, the first frequency domain resource and the first sub-frequency domain resource use the same frequency domain granularity, which can reduce the blind detection complexity at the signal receiver.

[0194] As another example, the first frequency domain unit and the second frequency domain unit can also be different, such as the first frequency domain resource and the first sub-frequency domain resource having different frequency domain granularities. For example, the first frequency domain unit is RB, and the second frequency domain unit is RE. Yet another example: the first frequency domain unit is RE, and the second frequency domain unit is RB. In this example, the first frequency domain resource and the first sub-frequency domain resource use different frequency domain granularities, which can satisfy the different functional requirements of the first signal and the second signal.

[0195] In one optional implementation, the value of N may be related to at least one of the bandwidth occupied by the first signal, the comb tooth value of the first signal, and the frequency scaling factor; alternatively, the value of N may be determined by at least one of the bandwidth occupied by the first signal, the comb tooth value of the first signal, and the frequency scaling factor. As an example, the first frequency domain unit is RB, and the number of RBs included in the first frequency domain resource (i.e., the value of N) may satisfy: m b / (K TC P F As another example, the first frequency domain unit is RE, and the number of REs included in the first frequency domain resource (i.e., the value of N) can satisfy: Where, m b K represents the bandwidth occupied by the first signal. TC This represents the comb value of the first signal. P F This is a frequency domain scaling factor used to increase or decrease the transmission bandwidth of the first signal. The number of REs included in RB, for example, 12.

[0196] In one optional implementation, the number of frequency domain units included in the bandwidth occupied by the first signal may be related to a frequency scaling factor, or the number of frequency domain units included in the bandwidth occupied by the first signal may be determined by the frequency scaling factor. As an example, the frequency domain unit is RB, and the number of RBs included in the bandwidth occupied by the first signal may satisfy: m b / P F As another example, the frequency domain unit is RE, and the number of REs included in the bandwidth occupied by the first signal can satisfy: Where, m b P F , Please refer to the above description; further details will not be repeated here.

[0197] In one alternative implementation, the value of H may be related to at least one of the bandwidth occupied by the second signal, the comb value of the second signal, and the frequency scaling factor; or, the value of H may be determined by at least one of the bandwidth occupied by the second signal, the comb value of the second signal, and the frequency scaling factor. For details, please refer to the description of the value of N, which will not be repeated here.

[0198] In one alternative implementation, the number of frequency domain units included in the bandwidth occupied by the second signal may be related to the frequency scaling factor, or the number of frequency domain units included in the bandwidth occupied by the second signal may be determined by the frequency scaling factor. For details, please refer to the description of the number of frequency domain units included in the bandwidth occupied by the first signal, which will not be repeated here.

[0199] The comb tooth value can also be called comb tooth number, comb tooth, or comb segment number, etc., and this application does not limit the naming of the comb tooth value. The comb tooth value of the first signal can be understood as: the comb tooth value mapping the first signal, or the frequency domain interval mapping the first signal, or the comb tooth value obtained by mapping the first signal, or the frequency domain interval obtained by mapping the first signal. The comb tooth value is a positive integer, such as 1, 2, 4, 6, 8, or 16, etc., and this application does not limit it. For example, if the frequency domain granularity of the comb tooth value is RB, the comb tooth value of the first signal is 1, indicating that each RB maps to the first signal; or, the comb tooth value of the first signal is 2, indicating that one of every two RBs maps to the first signal; or, the comb tooth value of the first signal is 4, indicating that one of every four RBs maps to the first signal. Other values ​​are similar and will not be listed one by one.

[0200] In one optional implementation, the first signal and the second signal may satisfy at least one of the following: the comb tooth values ​​of the first signal and the second signal are the same; or, the comb offset values ​​of the first signal and the second signal are the same. The comb tooth values ​​are as described above and will not be repeated here. In this implementation, the fact that the first signal and the second signal have the same comb tooth value means that the first signal and the second signal can be mapped to the same comb tooth, or that the first signal and the second signal can be mapped to two orthogonal comb teeth in the frequency domain, thus reducing the mapping complexity of the first signal and the second signal. The fact that the first signal and the second signal have the same comb offset value means that the first signal and the second signal can be mapped to the same comb tooth, thus reducing the mapping complexity of the first signal and the second signal.

[0201] The comb offset value can also be called comb offset, comb number offset, or comb segment offset, etc., and this application does not limit the naming of the comb offset value. This comb offset value indicates the offset of the first signal (or the second signal) mapped in the frequency domain. The comb offset value of the first signal can be understood as: the comb offset value mapped to the first signal, or the comb offset value obtained by mapping the first signal. The comb offset value of the second signal can be understood as: the comb offset value mapped to the second signal, or the comb offset value obtained by mapping the second signal. This comb offset value is a positive number, such as 0, 1, 2, 3, or 4, etc., and this application does not limit this.

[0202] For example, if the frequency domain granularity of the comb offset value is RB, a comb offset value of 0 for the first signal indicates that the mapping of the first signal starts from the RB corresponding to the lowest index in the first frequency domain resource; or, a comb offset value of 1 for the first signal indicates that the mapping of the first signal starts from the RB corresponding to (lowest index + 1) in the first frequency domain resource; or, a comb offset value of 2 for the first signal indicates that the mapping of the first signal starts from the RB corresponding to (lowest index + 2) in the first frequency domain resource. Other values ​​follow the same logic and will not be listed individually.

[0203] For example, if the frequency domain granularity of the comb offset value is RE, a comb offset value of 0 for the first signal indicates that the mapping of the first signal starts from the RE corresponding to the lowest index in the first frequency domain resource; or, a comb offset value of 1 for the first signal indicates that the mapping of the first signal starts from the RE corresponding to (lowest index + 1) in the first frequency domain resource; or, a comb offset value of 2 for the first signal indicates that the mapping of the first signal starts from the RE corresponding to (lowest index + 2) in the first frequency domain resource. Other values ​​follow the same logic and will not be listed individually.

[0204] Optionally, the comb tooth values ​​of the first signal and the second signal are the same, which can be replaced by: the comb tooth value of the mapped first signal being the same as the comb tooth value of the mapped second signal, or the frequency domain interval of the mapped first signal being the same as the frequency domain interval of the mapped second signal, or the comb tooth value of the mapped first signal being the same as the comb tooth value of the mapped second signal, or the frequency domain interval of the mapped first signal being the same as the frequency domain interval of the mapped second signal.

[0205] Optionally, the comb tooth offset values ​​of the first signal and the second signal are the same, which can be replaced by: the comb tooth offset value of the mapped first signal is the same as the comb tooth offset value of the mapped second signal, or the comb tooth offset value of the mapped first signal is the same as the comb tooth offset value of the mapped second signal.

[0206] As an example, the first signal and the second signal have the same comb tooth value, which may include at least one first frequency domain unit (e.g., denoted as I first frequency domain units, where I is a positive integer), or the comb tooth value may include at least one second frequency domain unit (e.g., denoted as J second frequency domain units, where J is a positive integer). In this example, the frequency domain granularity of mapping the comb tooth values ​​of the first signal and the second signal can be the same as the frequency domain granularity of the first frequency domain resource, or it can be the same as the frequency domain granularity of the first sub-frequency domain resource, which can adapt to different communication scenarios.

[0207] As an example, the first signal and the second signal have the same comb offset value. This comb offset value may include at least one first frequency domain unit (e.g., denoted as P first frequency domain units, where P is a positive integer), or the comb offset value may include at least one second frequency domain unit (e.g., denoted as Q second frequency domain units, where Q is a positive integer). In this example, the frequency domain granularity of mapping the comb offset values ​​of the first signal and the second signal can be the same as the frequency domain granularity of the first frequency domain resource, or it can be the same as the frequency domain granularity of the first sub-frequency domain resource, which can adapt to different communication scenarios.

[0208] For terms such as sensing, sensing signal, communication signal, synthetic fusion signal, and frequency domain unit, please refer to the aforementioned content; they will not be repeated here.

[0209] This application provides two design schemes (denoted as Scheme #1 and Scheme #2) for designing sensing and communication resources. It should be understood that Scheme #1 and Scheme #2 can be used individually or in combination. In other words, this application can implement the design of sensing and communication resources through Scheme #1 and / or Scheme #2.

[0210] Option 1: The first frequency domain resource includes the first sub-frequency domain resource, or the first sub-frequency domain resource belongs to the first frequency domain resource. Figure 3 illustrates this as an example where the first frequency domain resource includes the first sub-frequency domain resource. For example, the first frequency domain resource includes N first frequency domain units, and the first sub-frequency domain resource includes H second frequency domain units, where the N first frequency domain units include the H second frequency domain units. For example, the first sub-frequency domain resource can be some or all of the frequency domain resources in the first frequency domain resource. For ease of understanding, unless otherwise specified, the following description will use the example of the first sub-frequency domain resource being a portion of the frequency domain resources in the first frequency domain resource.

[0211] As an example, the inclusion of a first sub-frequency domain resource in the first frequency domain resource can be seen in Figure 4(1). Figure 4 uses RB as an example for the first frequency domain unit. As shown in Figure 4(1), the first frequency domain resource includes 9 RBs, namely RB#0, RB#3, RB#6, RB#9, RB#12, RB#15, RB#18, RB#21 and RB#24. If both the second and first frequency domain units are RBs, the first frequency domain resource includes a first sub-frequency domain resource, which may include RB#9, RB#12 and RB#15, that is, the first sub-frequency domain resource includes 3 RBs. Alternatively, if the second frequency domain unit is different from the first frequency domain unit, such as the second frequency domain unit being RE, the first frequency domain resource includes a first sub-frequency domain resource, which may include some or all REs in RB#9, some or all REs in RB#12 and some or all REs in RB#15. For example, the first sub-frequency domain resource may include There are one RE. Figure 4 shows an example where both the second and first frequency domain units are RBs.

[0212] In one optional implementation, the first frequency domain resource includes a first sub-frequency domain resource, which may include: the bandwidth of the first frequency domain resource including the bandwidth of the first sub-frequency domain resource; or the bandwidth of the first frequency domain resource being greater than or equal to the bandwidth of the first sub-frequency domain resource. The bandwidth of the first frequency domain resource can be understood as: the bandwidth carrying the first signal, or the bandwidth including the first frequency domain resource, or a continuous frequency domain resource including the first frequency domain resource, or the bandwidth to which the first frequency domain resource belongs, or the frequency domain range carrying the first signal. For example, the first frequency domain resource may be part or all of the frequency domain resources within the bandwidth of the first frequency domain resource. The bandwidth of the first sub-frequency domain resource can be understood as: the bandwidth carrying the second signal, or the bandwidth including the first sub-frequency domain resource, or a continuous frequency domain resource including the first sub-frequency domain resource, or the bandwidth to which the first sub-frequency domain resource belongs, or the frequency domain range carrying the second signal. For example, the first sub-frequency domain resource may be part or all of the frequency domain resources within the bandwidth of the first sub-frequency domain resource.

[0213] For example, the first frequency domain resource includes N first frequency domain units, and the bandwidth of the first frequency domain resource may include N1 first frequency domain units. The first sub-frequency domain resource includes H second frequency domain units, and the bandwidth of the first sub-frequency domain resource may include H1 second frequency domain units. The N1 first frequency domain units include H1 second frequency domain units, where N1 is an integer greater than or equal to N, and H1 is an integer greater than or equal to H.

[0214] As an example, the bandwidth of the first frequency domain resource includes the bandwidth of the first sub-frequency domain resource, as shown in Figure 4(2). As shown in Figure 4(2), the bandwidth of the first frequency domain resource includes 27 RBs, namely RB#0 to RB#26, of which RB#0, RB#3, RB#6, RB#9, RB#12, RB#15, RB#18, RB#21 and RB#24 are first frequency domain resources; the bandwidth of the first frequency domain resource includes the bandwidth of the first sub-frequency domain resource, which may include 9 RBs, namely RB#9 to RB#17, of which RB#9, RB#12 and RB#15 are first sub-frequency domain resources.

[0215] As an example, the bandwidth of the first frequency domain resource may include the bandwidth of the first sub-frequency domain resource, and the first frequency domain resource may not completely include the first sub-frequency domain resource. For example, the first frequency domain unit is RE, the second frequency domain unit is RB, the bandwidth of the first frequency domain resource includes 27 RBs, namely RB#0 to RB#26, and the bandwidth of the first sub-frequency domain resource includes 9 RBs, namely RB#9 to RB#17. The bandwidth of the first frequency domain resource includes the bandwidth of the first sub-frequency domain resource. Further, the first frequency domain resources may include some or all of the REs among RB#0, RB#3, RB#6, RB#9, RB#12, RB#15, RB#18, RB#21 and RB#24, and the first sub-frequency domain resources may include RB#9, RB#12 and RB#15; if the first frequency domain resources include some of the REs among RB#9, RB#12 and RB#15, then the first frequency domain resources do not completely exclude the first sub-frequency domain resources; if the first frequency domain resources include all of the REs among RB#9, RB#12 and RB#15, then the first frequency domain resources include the first sub-frequency domain resources.

[0216] In one optional implementation, the first frequency domain resource can be an integer multiple of the first sub-frequency domain resource, such as M times; and / or, the bandwidth of the first frequency domain resource can be an integer multiple of the bandwidth of the first sub-frequency domain resource, such as M times. Where M is a positive integer, such as 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10, etc. This application does not limit the value of M. For example, if the first sub-frequency domain resource is H RBs, then the first frequency domain resource can be M × H RBs. As another example, if the first frequency domain resource is N RBs, then the first sub-frequency domain resource can be N / M RBs. For example, if the bandwidth of the first sub-frequency domain resource can include H1 RBs, then the bandwidth of the first frequency domain resource can be M × H1 RBs. As another example, if the bandwidth of the first frequency domain resource can include N1 RBs, then the bandwidth of the first sub-frequency domain resource can be N1 / M RBs. It should be understood that the multiple between the first frequency domain resource and the first sub-frequency domain resource, and the multiple between the bandwidth of the first frequency domain resource and the first sub-frequency domain resource, can be the same or different.

[0217] In one alternative implementation, the first frequency domain resource and the first sub-frequency domain resource may satisfy any of the following.

[0218] 1) The lowest frequency in the first frequency domain resource is the same as the lowest frequency in the first sub-frequency domain resource.

[0219] The lowest frequency in the first frequency domain resource is the same as the lowest frequency in the first sub-frequency domain resource. This can be understood as the lowest frequency of the mapped first signal being the same as the lowest frequency of the mapped second signal. Having the lowest frequency in the first frequency domain resource being the same as the lowest frequency in the first sub-frequency domain resource helps reduce the complexity of signal mapping.

[0220] The lowest frequency can be replaced with: the minimum frequency, the frequency domain unit corresponding to the minimum index, or the frequency domain unit corresponding to the lowest index. Correspondingly, if the lowest frequency in the first frequency domain resource is the same as the lowest frequency in the first sub-frequency domain resource, it can be replaced with: the minimum frequency in the first frequency domain resource is the same as the minimum frequency in the first sub-frequency domain resource; or it can be replaced with: the first frequency domain unit corresponding to the minimum index in the first frequency domain resource is the same as the second frequency domain unit corresponding to the minimum index in the first sub-frequency domain resource; or it can be replaced with: the first frequency domain unit corresponding to the lowest index in the first frequency domain resource is the same as the second frequency domain unit corresponding to the lowest index in the first sub-frequency domain resource. For example, the RB of the lowest index mapping the first signal is the same as the RB of the lowest index mapping the second signal. As another example, the RE of the lowest index mapping the first signal is the same as the RE of the lowest index mapping the second signal.

[0221] For example, the first frequency domain resource includes four RBs: RB#0, RB#2, RB#4, and RB#6. The first frequency domain resource includes a first sub-frequency domain resource. Assuming the first sub-frequency domain resource includes two RBs, then the first sub-frequency domain resource can include RB#0 and RB#2. The RB corresponding to the lowest index in the first frequency domain resource is the same as the RB corresponding to the lowest index in the first sub-frequency domain resource, which is RB#0.

[0222] 2) The highest frequency in the first frequency domain resource is the same as the highest frequency in the first sub-frequency domain resource.

[0223] The highest frequency in the first frequency domain resource is the same as the highest frequency in the first sub-frequency domain resource. This can be understood as the highest frequency of the mapped first signal being the same as the highest frequency of the mapped second signal. Having the highest frequency in the first frequency domain resource being the same as the highest frequency in the first sub-frequency domain resource helps reduce the complexity of signal mapping.

[0224] The highest frequency can be replaced with: the maximum frequency, the frequency domain unit corresponding to the maximum index, or the frequency domain unit corresponding to the highest index. Correspondingly, if the highest frequency in the first frequency domain resource is the same as the highest frequency in the first sub-frequency domain resource, it can be replaced with: the maximum frequency in the first frequency domain resource is the same as the maximum frequency in the first sub-frequency domain resource; or it can be replaced with: the first frequency domain unit corresponding to the maximum index in the first frequency domain resource is the same as the second frequency domain unit corresponding to the maximum index in the first sub-frequency domain resource; or it can be replaced with: the first frequency domain unit corresponding to the highest index in the first frequency domain resource is the same as the second frequency domain unit corresponding to the highest index in the first sub-frequency domain resource. For example, the RB mapping the highest index of the first signal is the same as the RB mapping the highest index of the second signal. For example, the RE mapping the highest index of the first signal is the same as the RE mapping the highest index of the second signal.

[0225] For example, the first frequency domain resource includes four RBs: RB#0, RB#2, RB#4, and RB#6. The first frequency domain resource includes a first sub-frequency domain resource. Assuming the first sub-frequency domain resource includes two RBs, then the first sub-frequency domain resource can include RB#4 and RB#6. The RB corresponding to the highest index in the first frequency domain resource is the same as the RB corresponding to the highest index in the first sub-frequency domain resource, which is RB#6.

[0226] 3) The center frequency point of the first frequency domain resource is the same as the center frequency point of the first sub-frequency domain resource.

[0227] The center frequency point of the first frequency domain resource is the same as the center frequency point of the first sub-frequency domain resource. This can be understood as the center frequency point of the mapped first signal being the same as the center frequency point of the mapped second signal. Having the same center frequency point in both the first and first sub-frequency domain resources helps reduce the complexity of blind detection at the signal receiver.

[0228] For example, the first frequency domain resource includes RB#0, RB#3, RB#6, RB#9, RB#12, RB#15, RB#18, RB#21 and RB#24, and the center frequency point of the first frequency domain resource is RB#12; the first sub-frequency domain resource includes RB#9, RB#12 and RB#15, and the center frequency point of the first sub-frequency domain resource is RB#12; the center frequency point of the first frequency domain resource is the same as the center frequency point of the first sub-frequency domain resource, which is RB#12.

[0229] In one optional implementation, the first frequency domain resource and the first sub-frequency domain resource may satisfy at least one of the following: the cyclic prefix (CP) corresponding to the first frequency domain resource is the same as the CP corresponding to the first sub-frequency domain resource, such as both the CPs corresponding to the first frequency domain resource and the first sub-frequency domain resource being normal CPs or extended CPs; or, the sub-carrier space (SCS) corresponding to the first frequency domain resource is the same as the SCS corresponding to the first sub-frequency domain resource. This implementation helps reduce the signal mapping complexity at the channel transmitter and the blind detection and decoding complexity at the signal receiver.

[0230] In Scheme 1 above, the first frequency domain resource includes the first sub-frequency domain resource, meaning that both sensing signals and communication signals can be transmitted on the first frequency domain resource. In other words, the signal transmitted on the first frequency domain resource (such as the first signal) can be used for both sensing and communication, which saves signaling overhead and helps increase spectral efficiency. Furthermore, if the first frequency domain resource is larger than the first sub-frequency domain resource—that is, the first sub-frequency domain resource is a portion of the first frequency domain resource—the frequency domain resource occupied by the sensing signal is larger than that occupied by the communication signal, allowing the sensing signal to be transmitted over a wider bandwidth. Generally, a wider bandwidth results in better sensing performance. Therefore, Scheme 1 above can also improve sensing performance, such as increasing ranging accuracy.

[0231] Option 2: The first signal is generated from a first sequence, and the second signal is generated from a second sequence. The first sequence includes the second sequence. Since the first sequence includes the second sequence, the frequency domain resources mapped by the first sequence (e.g., denoted as the first frequency domain resource) can include the frequency domain resources mapped by the second sequence (e.g., denoted as the first sub-frequency domain resource). That is, it indirectly indicates that the frequency domain resources occupied by the first signal include the frequency domain resources occupied by the second sequence, thereby realizing the design of sensing resources and communication resources.

[0232] Optionally, the first signal is generated from a first sequence, which may include: the first signal being the first sequence. Optionally, the second signal is generated from a second sequence, which may include: the second signal being the second sequence.

[0233] Optionally, the first sequence can also be referred to as the base sequence of the first signal. As an example, the first sequence can be a Zadoff-Chu (ZC) sequence, and the first sequence includes the second sequence. For example, the first signal can be generated based on a low-peak-to-average power ratio (low-PAPR) sequence type 1, and the first sequence includes the second sequence. As another example, the first signal can be generated based on a low-PAPR sequence type 2, and the first sequence includes the second sequence. As yet another example, the first sequence can be a Gold sequence, and the first sequence includes the second sequence. For example, the first signal can be generated based on a pseudo-random sequence, and the first sequence includes the second sequence. It is understood that this application does not limit the implementation form of the first sequence.

[0234] Optionally, the second sequence can also be referred to as the base sequence of the second signal. As an example, the first and second sequences can be Zadoff-Chu (ZC) sequences. For example, the first and second signals can be generated based on low-peak-to-average power ratio (low-PAPR) sequence type 1. As another example, the first and second signals can be generated based on low-PAPR sequence type 2. As yet another example, the first and second sequences can be Gold sequences. For example, the first and second signals can be generated based on pseudo-random sequences. Understandably, this application does not limit the implementation form of the second sequence.

[0235] In one alternative implementation, the first sequence includes a second sequence, which can be a portion or all of the first sequence. As an example, the second sequence consists of K elements, where K is a positive integer, and is a partial sequence of the first sequence, and can include any of the following:

[0236] 1) The second sequence consists of the first K elements of the first sequence. For example, the first sequence is denoted as {s0, s1, ..., s...} L-1 Let L be the length of the first sequence, and the second sequence consist of the first K elements of the first sequence. Then the second sequence can be {s0, s1, ..., s2}. K}

[0237] 2) The second sequence consists of K consecutive elements from the first sequence. For example, the first sequence is denoted as {s0, s1, ..., s...}. L-1 Let L be the length of the first sequence, and the second sequence consist of K consecutive elements from the first sequence. Then the second sequence can be {s}. i s i+1 , ..., s i+K-1}, where i is an integer greater than or equal to 0 and less than or equal to (LK). Optionally, the second sequence may consist of the middle K consecutive elements of the first sequence.

[0238] 3) The second sequence consists of the last K elements of the first sequence. For example, the first sequence is denoted as {s0, s1, ..., s...} L-1 Let L be the length of the first sequence, and the second sequence consist of the last K elements of the first sequence. Then the second sequence can be {s}. L-1-K s L-K , ..., s L-1}

[0239] 4) The second sequence can be composed of any K elements from the first sequence. For example, the first sequence is denoted as {s0, s1, ..., s...} L-1}, where L is the length of the first sequence, and the second sequence can be {s0, s1, ..., s}. L-1 It consists of any K elements in}.

[0240] As an example, regarding the second sequence being a partial sequence of the first sequence, see Figure 5(1). In Figure 5(1), the first sequence includes 27 elements: 001 111 100 011 111 110 011 111 000. The second sequence is a partial sequence of the first sequence; assuming the second sequence includes 9 elements, it could be: 011 111 110. It should be understood that the values ​​in Figure 5 are merely examples, and this application does not limit them.

[0241] In another optional implementation, the first sequence includes the second sequence, which can be: the first sequence is a repeating sequence of the second sequence. Optionally, the first sequence being a repeating sequence of the second sequence can be understood as: the first sequence being a second sequence repeatedly mapped in the frequency domain. For example, the first sequence may include a second sequence repeatedly mapped in the frequency domain at least once (e.g., denoted as X times, where X is a positive integer). The value of X is not limited, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10.

[0242] As an example, the first sequence being a repeating sequence of the second sequence can be seen in Figure 5(2). In Figure 5(2), the second sequence includes 9 elements: 011 111 110. The first sequence is a repeating sequence of the second sequence. Assuming that the first sequence includes 27 elements, the first sequence can be: 011 111 110 011 111 110 011 111 110, that is, the first sequence is the second sequence that is repeatedly mapped 3 times in the frequency domain.

[0243] In one optional implementation, the length of the first sequence is an integer multiple of the length of the second sequence, such as G times. Here, G is a positive integer, such as 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. Optionally, the value of G can be the same as the value of X mentioned above, that is, the value of G and the number of times the second sequence is repeatedly mapped are the same. This application does not limit the value of G. For example, if the length of the first sequence is L1, then the length of the second sequence can be L1 / G. As another example, if the length of the second sequence is L2, then the length of the first sequence can be G×L2. As an example, the length of the first sequence can satisfy: The length of the second sequence can satisfy: Where, m b K represents the bandwidth occupied by the first signal. TC P is the comb value of the first signal. F This is a frequency domain scaling factor used to reduce the transmission bandwidth of the first signal. The number of REs included in RB.

[0244] As an example, the first signal is mapped onto RE#j, where j satisfies: j = {0, 1, ..., L-1}, and L is the length of the first sequence. The second signal can be mapped onto RE#k, where k satisfies: k = {A, A+1, ..., A+L / G-1}; or k satisfies: Among them, G and Please refer to the foregoing description. A and B are integers. The value of A can be predefined, preconfigured, or configured by a third device; this application does not limit this. The value of B can be predefined, preconfigured, or configured by a third device; this application does not limit this. Optionally, A can default to 0. Optionally, B can default to 0.

[0245] It is understandable that the frequency domain resources mapped by the first sequence can be referred to in the description of the first frequency domain resources, and the frequency domain resources mapped by the second sequence can be referred to in the description of the first sub-frequency domain resources, which will not be repeated here.

[0246] In Scheme 2 above, the first signal is generated from a first sequence, and the second signal is generated from a second sequence. The first sequence includes the second sequence, so the frequency domain resources mapped by the first sequence can include the frequency domain resources mapped by the second sequence. That is, it indirectly indicates that the frequency domain resources occupied by the first signal include the frequency domain resources occupied by the second sequence, thereby realizing the design of sensing and communication resources. In addition, if the frequency domain resources mapped by the first sequence are greater than the frequency domain resources mapped by the second sequence, that is, the frequency domain resources mapped by the second sequence are a portion of the frequency domain resources mapped by the first sequence, the frequency domain resources occupied by the sensing signal are greater than the frequency domain resources occupied by the communication signal. This allows the sensing signal to be transmitted in a wider bandwidth. Generally, the wider the bandwidth, the better the sensing performance. Therefore, Scheme 2 above can also improve sensing performance, such as improving ranging accuracy.

[0247] In S301, the first device may determine a first frequency domain resource and / or determine a first sub-frequency domain resource. Optionally, the first frequency domain resource may be predefined, preconfigured, configured by the first device, or configured by the third device; this application does not limit this. Optionally, the first sub-frequency domain resource may be predefined, preconfigured, configured by the first device, or configured by the third device; this application does not limit this.

[0248] In one alternative implementation, the first device may send a second message that can be used to indicate a first frequency domain resource, and / or the second message can be used to indicate a first sub-frequency domain resource. For example, the first device may send a second message to a second device; correspondingly, the second device receives the second message from the first device.

[0249] In another alternative implementation, the first device may receive a second message that can be used to indicate a first frequency domain resource, and / or the second message can be used to indicate a first sub-frequency domain resource. For example, a third device may send a second message to the first device; correspondingly, the first device receives a second message from the third device. The third device may be the second device, or a device other than the first and second devices.

[0250] Optionally, the second message can be understood as a configuration message for the sensing signal and / or a configuration message for the communication signal.

[0251] As an example, the second message may indicate a first frequency domain resource and / or a first sub-frequency domain resource through a field. For example, the second message may include a fourth field that can be used to indicate the first frequency domain resource and / or the first sub-frequency domain resource.

[0252] As another example, the second message may indicate the first frequency domain resource and / or the first sub-frequency domain resource through two fields.

[0253] For example, the second message includes a fifth field and a sixth field, where the sixth field can take a third value and / or a fourth value. The third value can be used to indicate that the fifth field indicates a first frequency domain resource, and the fourth value can be used to indicate that the fifth field indicates a first sub-frequency domain resource. The third value indicating that the fifth field indicates a first frequency domain resource can be replaced with: the third value indicating that the frequency domain resource indicated by the fifth field is a first frequency domain resource; or it can be replaced with: the third value indicating that the frequency domain resource indicated by the fifth field is a frequency domain resource used for sensing; or it can be replaced with: the third value indicating that the frequency domain resource indicated by the fifth field is a frequency domain resource used to carry a first signal. The fourth value indicating that the fifth field indicates a first sub-frequency domain resource can be replaced with: the fourth value indicating that the frequency domain resource indicated by the fifth field is a first sub-frequency domain resource; or it can be replaced with: the fourth value indicating that the frequency domain resource indicated by the fifth field is a frequency domain resource used for communication; or it can be replaced with: the fourth value indicating that the frequency domain resource indicated by the fifth field is a frequency domain resource used to carry a second signal. For example, the third value is 0 and the fourth value is 1; or the third value is 1 and the fourth value is 0. This application does not limit the third and fourth values.

[0254] For example, the second message includes a fifth field and a seventh field. The value of the seventh field may include at least one of the following: a fifth value, a sixth value, or a seventh value. Specifically, the fifth value can be used to indicate that the fifth field indicates frequency domain resources used to carry a first signal that does not include the second signal; the sixth value can be used to indicate that the fifth field indicates frequency domain resources used to carry the second signal; and the seventh value can be used to indicate that the fifth field indicates frequency domain resources used to carry a first signal that includes the second signal. A first signal that does not include the second signal can be understood as: the first signal is used only for sensing. A first signal that includes the second signal can be understood as: some or all of the signals in the first signal are used for both sensing and communication.

[0255] Optionally, in the above example, the fourth field (or fifth field) may indicate the configuration information of the first frequency domain resource, such as indicating at least one of the following: the start position of the first frequency domain resource, the number of first frequency domain units included in the first frequency domain resource, and the end position of the first frequency domain resource. Optionally, indicating the first frequency domain resource may be replaced by indicating the configuration information of the first frequency domain resource.

[0256] Optionally, in the above example, the fourth field (or fifth field) may indicate the configuration information of the first sub-frequency domain resource, such as indicating at least one of the following: the start position of the first sub-frequency domain resource, the number of second frequency domain units included in the first sub-frequency domain resource, and the end position of the first sub-frequency domain resource. Optionally, indicating the first sub-frequency domain resource may be replaced by indicating the configuration information of the first sub-frequency domain resource.

[0257] It should be understood that this application does not limit the implementation form of the second message. Furthermore, the configuration message for the first frequency domain resource (or the configuration message for the first signal) and the configuration message for the first sub-frequency domain resource (or the configuration message for the second signal) can be the same message or different messages; this application does not limit this. For example, the first device can send message #1 and message #2, where message #1 indicates the first frequency domain resource and message #2 indicates the first sub-frequency domain resource; this application does not limit the sending order of message #1 and message #2. As another example, the first device can receive message #1 and message #2, where message #1 indicates the first frequency domain resource and message #2 indicates the first sub-frequency domain resource; this application does not limit the receiving order of message #1 and message #2.

[0258] S302: The second device determines the first frequency domain resource.

[0259] Alternatively, S302 can also be expressed as: the second device determines the first sub-frequency domain resource, or the second device determines the first frequency domain resource and the first sub-frequency domain resource.

[0260] S302 is an optional step, indicated by a dashed line in Figure 3.

[0261] Optionally, the first frequency domain resource can be predefined, preconfigured, configured for the second device, or configured for the third device; this application does not limit this. Optionally, the first sub-frequency domain resource can be predefined, preconfigured, configured for the second device, or configured for the third device; this application does not limit this.

[0262] In one alternative implementation, the second device may send a second message that can be used to indicate a first frequency domain resource, and / or the second message can be used to indicate a first sub-frequency domain resource. For example, the second device may send a second message to the first device; correspondingly, the first device receives the second message from the second device.

[0263] In another alternative implementation, the second device may receive a second message that can be used to indicate a first frequency domain resource, and / or the second message can be used to indicate a first sub-frequency domain resource. For example, a third device may send a second message to the second device; correspondingly, the second device receives the second message from the third device. The third device may be the first device, or a device other than the first and second devices.

[0264] The second message, the first frequency domain resource, and the first sub-frequency domain resource can be referred to in the description of S301, and will not be repeated here.

[0265] Understandably, the execution order of S301 and S302 is merely an example, and this application does not limit it. For example, the second device may also determine the first frequency domain resource before the first device determines the first frequency domain resource.

[0266] S303: The first device sends a first signal, or the first device sends a second signal.

[0267] The first signal is carried by a first frequency domain resource. For example, the first device transmits the first signal on the first frequency domain resource. The second signal is carried by a first sub-frequency domain resource. For example, the first device transmits the second signal on the first sub-frequency domain resource. The first signal, the second signal, the first frequency domain resource, and the first sub-frequency domain resource are described in S301 and will not be repeated here.

[0268] Understandably, this application does not limit the time-domain resources occupied by the first signal and the second signal. As an example, the time-domain resources occupied by the first signal are the same as those occupied by the second signal; or, the time-domain resources occupied by the first signal partially or completely overlap with those occupied by the second signal; or, the time-domain resources occupied by the first signal are part or all of the time-domain resources occupied by the second signal; or, the time-domain resources occupied by the second signal are part or all of the time-domain resources occupied by the first signal. For example, the number of symbols occupied by the first signal is greater than the number of symbols occupied by the second signal. As another example, the number of symbols occupied by the first signal is equal to the number of symbols occupied by the second signal. As yet another example, the number of symbols occupied by the first signal is less than the number of symbols occupied by the second signal.

[0269] Optionally, the starting time unit occupied by the first signal in the time slot may be the same as or different from the starting time unit occupied by the second signal in the time slot. For example, the starting symbol of the first signal in the time slot may be the same as or different from the starting symbol of the second signal in the time slot.

[0270] In one optional implementation, a first signal may be carried on a first time unit, and a second signal may be carried on a first time unit. The number of first time units can be one or more, and this application does not limit this. For example, the first signal occupies resource #1, and the second signal occupies resource #2. Both resource #1 and resource #2 include the first time unit in the time domain. Resource #1 includes a first frequency domain resource in the frequency domain, and resource #2 includes a first sub-frequency domain resource in the frequency domain, and the first frequency domain resource includes the first sub-frequency domain resource.

[0271] In this embodiment of the application, the first device may transmit a first signal; or, the first device may transmit a second signal. The first signal may be used solely for sensing, or it may be used for both sensing and communication. For example, the first signal may include the second signal, or the second signal may be a sub-signal of the first signal.

[0272] As an example, the first device transmits a first signal, wherein the first signal does not include a second signal, as shown in (1) of FIG6. That is, the first signal is used only for sensing. For example, the first signal carried on a first frequency domain resource is used for sensing.

[0273] As an example, the first device transmits a second signal, as shown in (2) of Figure 6. The second signal is described in the foregoing description and will not be repeated here. For example, the first device may transmit the second signal only on the first sub-frequency domain resource. For example, the first device may transmit the second signal on the first sub-frequency domain resource, but not on frequency domain resources other than the first sub-frequency domain resource in the first frequency domain resource.

[0274] As an example, a first device transmits a first signal, wherein the first signal includes a second signal, or the second signal is a sub-signal of the first signal, as shown in (3) of Figure 6. In other words, the first signal is used for both sensing and communication; or, the first signal is used for sensing, and a portion of the first signal is also used for communication. For example, a signal carried on a first frequency domain resource is used for sensing, and a signal carried on a first sub-frequency domain resource is used for communication. For example, a signal carried on a first frequency domain resource is used for sensing, and a signal carried on a first sub-frequency domain resource is used for both sensing and communication. In this example, since the first signal carried on the first frequency domain resource is used for both sensing and communication, it can also be said that the first signal is used for both sensing and communication.

[0275] It should be understood that the second signal is a sub-signal of the first signal. The first device sends the first signal, which can also be understood as a complete signal.

[0276] In one optional implementation, the information carried by the second signal may be part or all of the information carried by the first signal; and / or, the second signal may be part or all of the signal in the first signal. Wherein, the information carried by the second signal may be part or all of the information carried by the first signal, which can be understood as: the payload carried by the second signal is part or all of the payload carried by the first signal; or as: the second sequence that generates the second signal is part or all of the sequence in the first sequence that generates the first signal; or as: the original information bits corresponding to the second signal are part or all of the original information bits corresponding to the first signal. The second signal being part or all of the signal in the first signal can be understood as: the waveform of the second signal is part or all of the waveform of the first signal.

[0277] The first device may transmit a first signal. Optionally, transmitting the first signal may include: the first device mapping the first signal onto a first frequency domain resource for transmission. As an example, the first signal may be mapped onto the first frequency domain resource by any of the following methods.

[0278] 1) The first signal is mapped from the lowest frequency of the first sub-frequency domain resource to the highest frequency of the first frequency domain resource, and then from the lowest frequency of the first frequency domain resource back to the lowest frequency of the first sub-frequency domain resource. The lowest and highest frequencies are described in S301 and will not be repeated here. Taking Figure 6 as an example, the first signal can be mapped sequentially from RB#9 to RB#12, RB#15, RB#18, RB#21, and RB#24, and then sequentially from RB#0 to RB#3 and RB#6. The first signal is preferentially mapped to the first sub-frequency domain resource within the first frequency domain resource, and then to the remaining frequency domain resources. This prioritizes the mapping of communication signals and improves communication performance. Optionally, the first signal mapped to RB#9, RB#12, and RB#15 can also be understood as the second signal.

[0279] 2) The first signal is mapped from the lowest frequency of the first frequency domain resource to the highest frequency of the first frequency domain resource. The lowest and highest frequencies are described in S301 and will not be repeated here. Taking Figure 6 as an example, the first signal can be mapped sequentially from RB#0 to RB#3, RB#6, RB#9, RB#12, RB#15, RB#18, RB#21, and RB#24. Mapping the first signal from the lowest frequency to the highest frequency of the first frequency domain resource is simple and reduces mapping complexity. Optionally, the first signal mapped to RB#9, RB#12, and RB#15 can also be understood as the second signal.

[0280] The first device can transmit a second signal. Optionally, transmitting the second signal may include: the first device mapping the second signal onto a first sub-frequency domain resource for transmission. For example, the second signal may be mapped from the lowest frequency of the first sub-frequency domain resource to the highest frequency of the first sub-frequency domain resource. The lowest and highest frequencies are described in S301 and will not be repeated here. Taking Figure 6 as an example, the second signal may be mapped sequentially from RB#9 to RB#12 and RB#15.

[0281] Understandably, the execution order of S302 and S303 is merely an example, and this application does not limit it. For example, the second device may also determine the first frequency domain resource after the first device sends the first signal or the second signal.

[0282] Next, either S304 or S305 can be executed; that is, S304 and S305 can be parallel steps, as indicated by the dashed box in Figure 3. For example, for a single-station sensing mode, S304 can be executed. For example, for a two-station sensing mode, S305 can be executed.

[0283] S304: The first device receives the third signal.

[0284] The third signal includes the echo signal of the first signal and / or the first signal, or the third signal includes the echo signal of the second signal and the second signal. Figure 3 illustrates an example where the third signal includes the echo signal of the first signal, or includes the echo signal of the second signal.

[0285] Optionally, the echo signal of the first signal may be the echo signal reflected by the first signal through the target; or the echo signal of the first signal may include the echo signal reflected by the first signal through the target and the echo signal reflected by the first signal through other tangible objects in the environment where the target is located; or the echo signal of the first signal may be a sum of the echo signal reflected by the first signal through the target and the echo signal reflected by the first signal through other tangible objects in the environment where the target is located. For ease of understanding, the following description uses the example of the echo signal of the first signal being the echo signal reflected by the target.

[0286] Optionally, the echo signal of the second signal may be the echo signal reflected by the target; or the echo signal of the second signal may include the echo signal reflected by the target and the echo signal reflected by other tangible objects in the environment where the target is located; or the echo signal of the second signal may be a sum of the echo signal reflected by the target and the echo signal reflected by other tangible objects in the environment where the target is located. For ease of understanding, the following description uses the example of the echo signal of the second signal being reflected by the target.

[0287] As an example, the third signal may be an echo signal of the first signal, or it may be an echo signal of the second signal. For example, the first device transmits the first signal and receives the echo signal reflected by the target, i.e., receives the third signal, which is an echo signal of the first signal. Optionally, if the second signal is a sub-signal of the first signal, the echo signal of the first signal may include the echo signal of the second signal. As another example, the first device transmits the second signal, which is used for sensing or for sensing and communication; and receives the echo signal reflected by the target, i.e., receives the third signal, which is an echo signal of the second signal.

[0288] As another example, the third signal can be the first signal, or the third signal can be the second signal. For example, the first device sends a first signal, which is received directly by the first device without being reflected by a target, i.e., it receives a third signal, which is the first signal. As another example, the first device sends a second signal, which is used for sensing or for sensing and communication, and is received directly by the first device without being reflected by a target, i.e., it receives a third signal, which is the second signal.

[0289] As another example, the third signal may include the first signal and its echo, or the third signal may include the second signal and its echo. For example, the first device transmits a first signal and receives an echo signal reflected by a target and a first signal not reflected by the target, i.e., receives a third signal, which includes the echo signal of the first signal and the first signal, or the third signal is a sum of the echo signal of the first signal and the first signal. As another example, the first device transmits a second signal for sensing or for sensing and communication; and the first device receives an echo signal reflected by a target and a second signal not reflected by the target, i.e., receives a third signal, which includes the echo signal of the second signal and the second signal, or the third signal is a sum of the echo signal of the second signal and the second signal.

[0290] Optionally, the first device receives the third signal and can perform corresponding processing based on the third signal, such as acquiring sensing data based on the third signal. This application does not limit this.

[0291] S305: The second device receives the fourth signal.

[0292] The fourth signal includes the echo signal of the first signal and / or the first signal, or the fourth signal includes the echo signal of the second signal and the second signal. Figure 3 illustrates an example where the fourth signal includes the echo signal of the first signal, or the fourth signal includes the echo signal of the second signal. For details regarding the echo signals of the first and second signals, please refer to the description in S304; further elaboration is omitted here.

[0293] As an example, the fourth signal may be an echo signal of the first signal, or it may be an echo signal of the second signal, or it may be the second signal itself. For example, a first device transmits a first signal; correspondingly, a second device receives an echo signal reflected from a target, i.e., receives a fourth signal, which is an echo signal of the first signal. Optionally, if the second signal is a sub-signal of the first signal, the echo signal of the first signal may include the echo signal of the second signal. As another example, a first device transmits a second signal used for sensing or for sensing and communication; correspondingly, a second device receives an echo signal reflected from a target, i.e., receives a fourth signal, which is an echo signal of the second signal.

[0294] As another example, the fourth signal can be the first signal, or it can be the second signal. For instance, the first device sends a first signal that is received directly by the second device without being reflected by a target; that is, the second device receives the fourth signal, which is the first signal. As another example, the first device sends a second signal used for sensing or for sensing and communication; this second signal is received directly by the second device without being reflected by a target; that is, the second device receives the fourth signal, which is the second signal. Yet another example, the first device sends a second signal used only for communication; accordingly, the second device receives the fourth signal, which is the second signal.

[0295] As another example, the fourth signal may include the first signal and its echo, or the fourth signal may include the second signal and its echo. For example, a first device transmits a first signal; a second device receives an echo signal reflected by a target and a first signal not reflected by the target, i.e., receives a fourth signal, which includes the echo signal of the first signal and the first signal, or the fourth signal is a sum of the echo signal of the first signal and the first signal. As another example, a first device transmits a second signal used for sensing or for sensing and communication; the second device receives an echo signal reflected by a target and a second signal not reflected by the target, i.e., receives a fourth signal, which includes the echo signal of the second signal and the second signal, or the fourth signal is a sum of the echo signal of the second signal and the second signal.

[0296] Optionally, the second device receives the fourth signal and can perform corresponding processing based on the fourth signal, such as acquiring sensing data based on the fourth signal, etc. This application does not limit this.

[0297] In the first sensing method described above, the first signal is carried by a first frequency domain resource and is used for sensing. The second signal is carried by a first sub-frequency domain resource and is used for communication. The first frequency domain resource includes the first sub-frequency domain resource, thus realizing the design of sensing and communication resources. Furthermore, the inclusion of the first sub-frequency domain resource in the first frequency domain resource means that both sensing and communication signals can be transmitted on the first frequency domain resource, saving signaling and resource overhead and improving spectral efficiency. Additionally, if the first frequency domain resource is larger than the first sub-frequency domain resource (i.e., the first sub-frequency domain resource is a portion of the first frequency domain resource), the frequency domain resource occupied by the sensing signal is larger than that occupied by the communication signal, allowing the sensing signal to be transmitted over a wider bandwidth. Generally, a wider bandwidth results in better sensing performance. Therefore, the first sensing method described above can also improve sensing performance, such as increasing ranging accuracy.

[0298] Figure 7 is a flowchart illustrating the second sensing method provided in this embodiment. This second sensing method can also be called a second integrated communication and sensing method, or a second integrated sensing and communication method. This embodiment can realize the design of sensing bandwidth and communication bandwidth. As shown in Figure 7, the method includes the following:

[0299] S701: The first device determines the first bandwidth.

[0300] Alternatively, S701 can also be described as: the first device determines the second bandwidth, or the first device determines the first bandwidth and the second bandwidth. Figure 7 illustrates this with the first device determining the first bandwidth as an example. Furthermore, S701 is an optional step, indicated by dashed lines in Figure 7.

[0301] The first bandwidth, also known as the sensing frequency domain resource, sensing frequency domain resource set, sensing bandwidth, or sensing BWP, is not limited in its naming in this application. This first bandwidth can be used to carry (or transmit) sensing signals. For example, some or all of the frequency domain resources in the first bandwidth can be used to transmit sensing signals. Optionally, the first frequency domain resource in the first sensing method described above can belong to the first bandwidth, such as the first frequency domain resource being some or all of the frequency domain resources in the first bandwidth.

[0302] It should be understood that "the first bandwidth is used to carry sensing signals" in this application means that the first bandwidth can be used to carry sensing signals. In practical applications, the first bandwidth may or may not carry sensing signals. For example, if sensing resources are allocated on the first bandwidth, then the first bandwidth carries sensing signals; if no sensing resources are allocated on the first bandwidth, then the first bandwidth may not carry sensing signals.

[0303] As an example, the first bandwidth may satisfy at least one of the following: the first bandwidth is greater than or equal to the bandwidth corresponding to the control-resource set (CORESET) with index value 0, i.e., the bandwidth corresponding to CORESET#0; the first bandwidth is greater than or equal to the initial bandwidth; or, the first bandwidth is greater than or equal to the default bandwidth. The initial bandwidth may be predefined or preconfigured, and this application does not limit this. For example, the initial bandwidth may be the initial communication bandwidth (e.g., initial communication BWP), or the initial sensing bandwidth (e.g., initial sensing BWP), or a predefined initial bandwidth in a future communication system (or sensing system), and this application does not limit this. The default bandwidth may be predefined or preconfigured, and this application does not limit this. For example, the default bandwidth may be the default communication bandwidth (e.g., default communication BWP), or the default sensing bandwidth (e.g., default sensing BWP), or a predefined default bandwidth in a future communication system (or sensing system), and this application does not limit this. Optionally, the default bandwidth may be the initial bandwidth. For example, the system information block 1 (SIB1) or master information block (MIB) received by the terminal device includes information indicating the initial bandwidth. If no default bandwidth is configured, the default bandwidth is the initial bandwidth. Furthermore, after the terminal device receives SIB1 or MIB, this default bandwidth can remain the initial bandwidth, or it can be configured to be a bandwidth greater than or less than the initial bandwidth as the default bandwidth.

[0304] Optionally, the first bandwidth being greater than or equal to the bandwidth corresponding to CORESET#0 can be replaced by: the frequency domain range of the first bandwidth including the frequency domain range of the bandwidth corresponding to CORESET#0. Optionally, the first bandwidth being greater than or equal to the initial bandwidth can be replaced by: the frequency domain range of the first bandwidth including the frequency domain range of the initial bandwidth. Optionally, the first bandwidth being greater than or equal to the default bandwidth can be replaced by: the frequency domain range of the first bandwidth including the frequency domain range of the default bandwidth. That is, the frequency domain range of the first bandwidth can include at least one of the following: the frequency domain range of the bandwidth corresponding to CORESET#0; the frequency domain range of the initial bandwidth; or the frequency domain range of the default bandwidth.

[0305] The second bandwidth, also known as communication frequency domain resource, communication frequency domain resource set, communication bandwidth, or communication BWP, is not limited in its naming in this application. This second bandwidth can be used to carry communication signals and / or sensing signals. For example, the second bandwidth may be used solely to carry communication signals, or solely to carry sensing signals, or it may be used to carry both sensing and communication signals. For example, some or all of the frequency domain resources in the second bandwidth may be used to transmit communication signals and / or sensing signals. Optionally, the first sub-frequency domain resource in the first sensing method described above may belong to the second bandwidth, such as the first sub-frequency domain resource being some or all of the frequency domain resources in the second bandwidth.

[0306] It should be understood that the phrase "the second bandwidth is used to carry communication signals and / or sensing signals" in this application indicates that the second bandwidth can be used to carry communication signals and / or sensing signals. In practical applications, the second bandwidth may or may not carry communication signals and / or sensing signals. For example, if communication resources are allocated to the second bandwidth, then the second bandwidth carries communication signals; if no communication resources are allocated to the second bandwidth, then the second bandwidth may not carry communication signals. Similarly, if sensing resources are allocated to the second bandwidth, then the second bandwidth carries sensing signals; if no sensing resources are allocated to the second bandwidth, then the second bandwidth may not carry sensing signals. Furthermore, if both communication and sensing resources are allocated to the second bandwidth, then the second bandwidth carries signals used for communication and sensing; if no sensing resources are allocated to the second bandwidth, then the second bandwidth may not carry signals used for communication and sensing.

[0307] As an example, the second bandwidth may satisfy at least one of the following: the second bandwidth is greater than or equal to the bandwidth corresponding to CORESET#0; the second bandwidth is greater than or equal to the initial communication bandwidth (such as the initial communication BWP); or, the second bandwidth is greater than or equal to the default communication bandwidth (such as the default communication BWP). The initial communication bandwidth may be predefined or preconfigured, and this application does not limit this. The default communication bandwidth may be predefined or preconfigured, and this application does not limit this. Optionally, the default communication bandwidth may be the initial communication bandwidth.

[0308] Optionally, the second bandwidth being greater than or equal to the bandwidth corresponding to CORESET#0 can be replaced by: the frequency domain range of the second bandwidth including the frequency domain range of the bandwidth corresponding to CORESET#0. Optionally, the second bandwidth being greater than or equal to the initial communication bandwidth can be replaced by: the frequency domain range of the second bandwidth including the frequency domain range of the initial communication bandwidth. Optionally, the second bandwidth being greater than or equal to the default communication bandwidth can be replaced by: the frequency domain range of the first bandwidth including the frequency domain range of the default communication bandwidth. That is, the frequency domain range of the second bandwidth can include at least one of the following: the frequency domain range of the bandwidth corresponding to CORESET#0; the frequency domain range of the initial communication bandwidth (e.g., the initial communication BWP); or the frequency domain range of the default communication bandwidth (e.g., the default communication BWP).

[0309] In this embodiment, the first bandwidth includes the second bandwidth, or the second bandwidth is part or all of the bandwidth in the first bandwidth. Optionally, the second bandwidth can be continuous frequency domain resources in the first bandwidth to reduce the configuration complexity of subsequent sensing signal frequency domain resources and / or communication signal frequency domain resources; or, the second bandwidth can also be discontinuous frequency domain resources in the first bandwidth to adapt to different communication scenarios.

[0310] In one optional implementation, the first bandwidth can be an integer multiple of the second bandwidth, such as Y times. Here, Y is a positive integer. The value of Y can be, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. This application does not limit the value of Y.

[0311] In one alternative implementation, the first bandwidth and the second bandwidth may satisfy any of the following.

[0312] 1) The lowest frequency in the first bandwidth is the same as the lowest frequency in the second bandwidth.

[0313] Optionally, the lowest frequency in the first bandwidth is the same as the lowest frequency in the second bandwidth, which can be understood as: the lowest frequency of the mapped first signal is the same as the lowest frequency of the mapped fifth signal. Having the lowest frequency in the first bandwidth be the same as the lowest frequency in the second bandwidth helps reduce the complexity of signal mapping and detection.

[0314] The lowest frequency can be replaced with: the minimum frequency, the frequency domain unit corresponding to the minimum index, or the frequency domain unit corresponding to the lowest index. Correspondingly, if the lowest frequency in the first bandwidth is the same as the lowest frequency in the second bandwidth, it can be replaced with: the minimum frequency in the first bandwidth is the same as the minimum frequency in the second bandwidth; or it can be replaced with: the first frequency domain unit corresponding to the minimum index in the first bandwidth is the same as the second frequency domain unit corresponding to the minimum index in the second bandwidth; or it can be replaced with: the first frequency domain unit corresponding to the lowest index in the first bandwidth is the same as the second frequency domain unit corresponding to the lowest index in the second bandwidth. For example, both the first and second frequency domain units are RB. Another example is that both the first and second frequency domain units are RE.

[0315] 2) The highest frequency in the first bandwidth is the same as the highest frequency in the second bandwidth.

[0316] Optionally, the highest frequency in the first bandwidth is the same as the highest frequency in the second bandwidth, which can be understood as: the highest frequency of the mapped first signal is the same as the highest frequency of the mapped fifth signal. Having the highest frequency in the first bandwidth be the same as the highest frequency in the second bandwidth helps reduce the complexity of signal mapping.

[0317] The highest frequency can be replaced with: the maximum frequency, the frequency domain unit corresponding to the maximum index, or the frequency domain unit corresponding to the highest index. Correspondingly, if the highest frequency in the first bandwidth is the same as the highest frequency in the second bandwidth, it can be replaced with: the maximum frequency in the first bandwidth is the same as the maximum frequency in the second bandwidth; or it can be replaced with: the first frequency domain unit corresponding to the maximum index in the first bandwidth is the same as the second frequency domain unit corresponding to the maximum index in the second bandwidth; or it can be replaced with: the first frequency domain unit corresponding to the highest index in the first bandwidth is the same as the second frequency domain unit corresponding to the highest index in the second bandwidth. For example, both the first and second frequency domain units are RB. For example, both the first and second frequency domain units are RE.

[0318] 3) The center frequency point of the first bandwidth is the same as the center frequency point of the second bandwidth.

[0319] Optionally, the center frequency point of the first bandwidth is the same as the center frequency point of the second bandwidth, which can be understood as: the center frequency point of the mapped first signal is the same as the center frequency point of the mapped fifth signal. Having the center frequency point of the first bandwidth be the same as the center frequency point of the second bandwidth helps reduce the complexity of blind detection at the signal receiver.

[0320] In one optional implementation, the first bandwidth and the second bandwidth may satisfy at least one of the following: the CP corresponding to the first bandwidth is the same as the CP corresponding to the second bandwidth, such as both the CP corresponding to the first bandwidth and the second bandwidth being normal CPs or both being extended CPs; or, the SCS corresponding to the first bandwidth is the same as the SCS corresponding to the second bandwidth. Through this implementation, the first signal and the fifth signal can be transmitted on the frequency-overlapping BWP, and the same CP and SCS can reduce interference between signal transmissions. Furthermore, this implementation also helps to reduce the complexity of signal mapping at the transmitting end and the complexity of blind detection and decoding at the receiving end.

[0321] The first signal is carried by the first bandwidth. Optionally, the first signal may be carried by the first frequency domain resources within the first bandwidth. Please refer to the description of S301 for the first signal and the first frequency domain resources; further details will not be provided here.

[0322] The fifth signal is carried by the second bandwidth. For example, the first device transmits the fifth signal on the second bandwidth. This fifth signal can be used for communication, sensing, or both. The fifth signal can be, for example, a reference signal, control signaling, or data; this application does not limit the implementation of the fifth signal. As an example, the fifth signal can be used only for communication; for example, it can be a communication SRS, communication CSI-RS, communication DMRS, physical random access channel, or SR. As yet another example, the fifth signal can be used only for sensing; for example, it can be a sensing SRS, sensing CSI-RS, sensing DMRS, SSB, physical random access channel, sensing SR, or PRS. As yet another example, the fifth signal can be used for both communication and sensing; for example, it can be an SRS for both communication and sensing, or a CSI-RS for both communication and sensing, or a DMRS for both communication and sensing, or a physical random access channel for both communication and sensing, or an SR for both communication and sensing. For details, please refer to the description of the second signal; further elaboration is unnecessary. This application does not limit the implementation method of the fifth signal.

[0323] Optionally, the fifth signal can be replaced by the second signal. For example, the fifth signal can be carried by the first sub-frequency domain resource in the second bandwidth. Please refer to the description of S301 for the second signal and the first sub-frequency domain resource, which will not be repeated here.

[0324] In one alternative implementation, the first bandwidth and the second bandwidth may include any of the following:

[0325] 1) The first bandwidth is the first BWP, and the second bandwidth is the second BWP. The second BWP can be part or all of the bandwidth in the first BWP. For example, the bandwidth of the first BWP can be an integer multiple of the bandwidth of the second BWP. For example, please refer to (1) and (2) in Figure 8 regarding the first BWP and the second BWP. In Figure 8 (1), the second BWP is part of the bandwidth in the first BWP. In Figure 8 (2), the second BWP is the first BWP, or the first BWP is the second BWP. Optionally, the first BWP can be called a sensing BWP, and the naming of the first BWP is not limited in this application. Optionally, the second BWP can be called a communication BWP, and the naming of the second BWP is not limited in this application. Optionally, the second BWP being part or all of the bandwidth in the first BWP can be replaced by: the first BWP includes the second BWP.

[0326] In other words, the first device maintains two BWPs, namely the first BWP and the second BWP. Similarly, the second device also maintains two BWPs, namely the first BWP and the second BWP.

[0327] 2) The first bandwidth is the first BWP, and part or all of the bandwidth in the first BWP is the second bandwidth, or in other words, the second bandwidth is part or all of the bandwidth in the first BWP. For example, the bandwidth of the first BWP can be an integer multiple of the second bandwidth. For example, regarding the second bandwidth being part of the bandwidth in the first BWP, please refer to (3) in Figure 8. In (3) of Figure 8, the second bandwidth is part of the bandwidth in the first BWP. Regarding the second bandwidth being the first BWP, please refer to (2) in Figure 8, which will not be repeated here. Optionally, the second bandwidth being part or all of the bandwidth in the first BWP can be replaced by: the first BWP includes the second bandwidth.

[0328] In other words, the first device maintains one BWP, namely the first BWP. Similarly, the second device also maintains one BWP, namely the first BWP. The second bandwidth is not a BWP. That is, the second bandwidth is used to transmit sensing signals and / or communication signals, but this second bandwidth is not a BWP.

[0329] 3) The second bandwidth is the second BWP, which is part or all of the bandwidth in the first bandwidth. For example, the first bandwidth may be an integer multiple of the bandwidth of the second BWP. For example, regarding the second BWP being part of the first bandwidth, please refer to (4) in Figure 8. In (4) of Figure 8, the second BWP is part of the first bandwidth. Regarding the second BWP being part of the first bandwidth, please refer to (2) in Figure 8, which will not be repeated here. Optionally, the second BWP being part or all of the first bandwidth can be replaced by: the first bandwidth includes the second BWP.

[0330] In other words, the first device maintains one BWP, i.e., the second BWP. Similarly, the second device also maintains one BWP, i.e., the second BWP. The first bandwidth is not a BWP. That is, the first bandwidth is used to transmit sensing signals, but this first bandwidth is not a BWP.

[0331] In S701, the first device may determine a first bandwidth and / or determine a second bandwidth. Optionally, the first bandwidth may be predefined, preconfigured, configured for the first device, or configured for a third device; this application does not limit this. Optionally, the second bandwidth may be predefined, preconfigured, configured for the first device, or configured for a third device; this application does not limit this. The third device may be the second device, or a device other than the first and second devices.

[0332] In one alternative implementation, the first device may send a first message that can be used to indicate a first bandwidth, and / or the first message can be used to indicate a second bandwidth. For example, the first device may send the first message to a second device; accordingly, the second device receives the first message from the first device.

[0333] In another alternative implementation, the first device may receive a first message that can be used to indicate a first bandwidth, and / or the first message can be used to indicate a second bandwidth. For example, a third device may send the first message to the first device; accordingly, the first device receives the first message from the third device. The third device may be a second device, or a device other than the first and second devices.

[0334] The first message may be carried in the second bandwidth, or it may be carried only in the second bandwidth, or it may not be carried in frequency domain resources other than the second bandwidth. The frequency domain range of the second bandwidth may be smaller than that of the first bandwidth. The first message is carried only in the second bandwidth. In other words, the frequency domain resource range of the first bandwidth indicated by the first message is larger than the frequency domain resource range that can carry the first message. This allows the configuration message (i.e., the first message) of the first and second bandwidths to be detected within a smaller frequency domain range (i.e., within the second bandwidth), which is easy to implement.

[0335] Optionally, the first message can be understood as a configuration message for the first bandwidth and / or a configuration message for the second bandwidth. In other words, the configuration of the first and second bandwidths can be achieved through the first message, and the same detection method and the same format can be used for decoding, which can reduce the complexity of blind detection and simplify the implementation.

[0336] As an example, a first message may indicate a first bandwidth and / or a second bandwidth via a field. For instance, a first message may include a first field that can be used to indicate a first bandwidth and / or a second bandwidth.

[0337] As another example, the first message can indicate the first bandwidth and / or the second bandwidth through two fields.

[0338] For example, the first message includes a second field and a third field, where the value of the third field includes a first value and / or a second value. The first value can be used to indicate that the second field indicates a first bandwidth, and the second value can be used to indicate that the second field indicates a second bandwidth. The first value indicating that the second field indicates a first bandwidth can be replaced by: the first value indicating that the bandwidth indicated by the second field is the first bandwidth; or it can be replaced by: the first value indicating that the bandwidth indicated by the second field is the bandwidth used for sensing; or it can be replaced by: the first value indicating that the bandwidth indicated by the second field is the bandwidth used to carry sensing signals. The second value indicating that the second field indicates a second bandwidth can be replaced by: the second value indicating that the bandwidth indicated by the second field is the second bandwidth; or it can be replaced by: the second value indicating that the bandwidth indicated by the second field is the bandwidth used for communication and / or sensing; or it can be replaced by: the second value indicating that the bandwidth indicated by the second field is the bandwidth used to carry communication signals and / or carry sensing signals. For example, the first value is 0 and the second value is 1; or the first value is 1 and the second value is 0. This application does not limit the first and second values.

[0339] For example, the first message includes a second field and an eighth field. The value of the eighth field can include at least one of the following: an eighth value, a ninth value, or a tenth value. Specifically, the eighth value can be used to indicate that the bandwidth indicated by the second field is for sensing; the ninth value can be used to indicate that the bandwidth indicated by the second field is for communication; and the tenth value can be used to indicate that the bandwidth indicated by the second field is for both sensing and communication. The option that the eighth value indicates the bandwidth indicated by the second field is for sensing can be replaced by: the eighth value indicates the bandwidth indicated by the second field is for carrying sensing signals. The option that the ninth value indicates the bandwidth indicated by the second field is for communication can be replaced by: the ninth value indicates the bandwidth indicated by the second field is for carrying communication signals. The option that the tenth value indicates the bandwidth indicated by the second field is for both sensing and communication can be replaced by: the tenth value indicates the bandwidth indicated by the second field is for carrying both sensing and communication signals.

[0340] Optionally, in the above examples, the second field (or the first field) may indicate bandwidth configuration information, such as indicating at least one of the following: the start position of the bandwidth, the number of frequency domain units included in the bandwidth, and the end position of the bandwidth. Optionally, indicating the first bandwidth may be replaced by indicating the configuration information of the first bandwidth. Optionally, indicating the second bandwidth may be replaced by indicating the configuration information of the second bandwidth.

[0341] In one optional implementation, the field length of the first field can be determined by the number of frequency domain units included in the second bandwidth, such as by the number of second frequency domain units included in the second bandwidth. Optionally, the field length of the second field can also be determined by the number of frequency domain units included in the second bandwidth.

[0342] It should be understood that this application does not limit the implementation form of the first message. Furthermore, the configuration message for the first bandwidth and the configuration message for the second bandwidth can be the same message or they can be different messages; this application does not limit this. For example, the first device can send message #3 and send message #4, where message #3 indicates the first bandwidth and message #4 indicates the second bandwidth; this application does not limit the sending order of messages #3 and #4. As another example, the first device can receive message #3 and receive message #4, where message #3 indicates the first bandwidth and message #4 indicates the second bandwidth; this application does not limit the receiving order of messages #3 and #4.

[0343] S702: The second device determines the first bandwidth.

[0344] Alternatively, S702 can also be described as: the second device determines the second bandwidth, or the second device determines the first bandwidth and the second bandwidth. Figure 7 illustrates this with the second device determining the first bandwidth as an example. Furthermore, S702 is an optional step, indicated by dashed lines in Figure 7.

[0345] Optionally, the first bandwidth can be predefined, preconfigured, configured for the first device, or configured for the third device; this application does not limit this. Optionally, the second bandwidth can be predefined, preconfigured, configured for the first device, or configured for the third device; this application does not limit this.

[0346] In one alternative implementation, the second device may send a first message that can be used to indicate a first bandwidth, and / or the first message can be used to indicate a second bandwidth. For example, the second device may send a first message to the first device; correspondingly, the first device receives the first message from the second device.

[0347] In another alternative implementation, the second device may receive a first message that can be used to indicate a first bandwidth, and / or the first message can be used to indicate a second bandwidth. For example, a third device may send the first message to the second device; accordingly, the second device receives the first message from the third device. The third device may be the first device, or a device other than the first and second devices.

[0348] The first message may be carried in the second bandwidth, or the first message may be carried only in the second bandwidth, or the first message may not be carried in frequency domain resources other than the second bandwidth.

[0349] The first message, first bandwidth, second bandwidth, etc., can be referred to in the description of S701 and will not be repeated here. It is understood that the execution order of S701 and S702 is only an example, and this application does not limit it. For example, the second device may determine the first bandwidth before the first device determines it.

[0350] S703: The first device sends a first signal, or the first device sends a fifth signal.

[0351] For example, the first device transmits a first signal on a first bandwidth. For example, the first device transmits a fifth signal on a second bandwidth.

[0352] As an example, the first device transmits a first signal over a first bandwidth. This first bandwidth does not include a second bandwidth. In other words, the first signal is used solely for sensing, and the first bandwidth carries the sensing signal. For example, the first signal carried over the first bandwidth is used for sensing.

[0353] As an example, the first device transmits a fifth signal on the second bandwidth. For example, the first device may transmit the fifth signal only on the second bandwidth, and this fifth signal may be used for sensing and / or communication. For example, the first device may transmit the fifth signal on the second bandwidth and not transmit signals on any bandwidth other than the second bandwidth in the first bandwidth.

[0354] As an example, a first device transmits a first signal over a first bandwidth, wherein a second bandwidth is a portion or all of the bandwidth of the first bandwidth. In other words, the first bandwidth is used for both sensing and communication; or, the first bandwidth is used to carry a sensing signal, and a portion of the first bandwidth can also be used to carry a communication signal. For example, the first bandwidth is used to carry a sensing signal, and the second bandwidth within the first bandwidth is used to carry a communication signal. For example, the first bandwidth is used to carry a sensing signal, and the second bandwidth within the first bandwidth is used to carry both a communication signal and a sensing signal. In this example, since the second bandwidth within the first bandwidth is used to carry both sensing and communication signals, it can also be said that the first bandwidth is used to carry both sensing and communication signals.

[0355] In one optional implementation, the first device may determine the frequency domain resources occupied by the first signal (i.e., the first frequency domain resources), and / or, the first device may determine the frequency domain resources occupied by the fifth signal. The first frequency domain resources belong to a first bandwidth. The frequency domain resources occupied by the fifth signal belong to a second bandwidth. Optionally, the first frequency domain resources include the frequency domain resources occupied by the fifth signal.

[0356] As mentioned above, the fifth signal can be replaced by the second signal. Next, we will use the example of the fifth signal being the second signal for explanation. Accordingly, the frequency domain resources occupied by this fifth signal are the first sub-frequency domain resources. These first sub-frequency domain resources belong to the second bandwidth.

[0357] For example, the first device may send a second message or receive a second message. The second message may be used to indicate a first frequency domain resource, and / or the second message may be used to indicate a first sub-frequency domain resource. Specific implementation details can be found in the description of S301, and will not be repeated here.

[0358] The second message may be carried within the second bandwidth, or it may be carried only within the second bandwidth, or it may not be carried in frequency domain resources other than the second bandwidth. The frequency domain range of the second bandwidth may be smaller than that of the first bandwidth. The second message is carried only within the second bandwidth, which allows for the detection of configuration messages (i.e., the second message) for the first frequency domain resources and the first sub-frequency domain resources within a smaller frequency domain range (i.e., within the second bandwidth), making it easy to implement.

[0359] The aforementioned second message may include a fourth field, which can be used to indicate the first frequency domain resource and / or indicate the first sub-frequency domain resource. In an optional implementation, the field length of the fourth field may be determined by the number of frequency domain units included in the second bandwidth, such as by the number of second frequency domain units included in the second bandwidth. Optionally, the field length of the fifth field may also be determined by the number of frequency domain units included in the second bandwidth. The fourth field, fifth field, and second frequency domain units are described in S301 and will not be repeated here.

[0360] Understandably, the execution order of S702 and S707 is merely an example, and this application does not limit it. For example, the second device may also determine the first bandwidth after the first device sends the first signal or the fifth signal.

[0361] Next, either S704 or S705 can be executed; that is, S704 and S705 can be parallel steps, as indicated by the dashed box in Figure 7. For example, for a single-station sensing mode, S704 can be executed. For example, for a dual-station sensing mode, S705 can be executed.

[0362] S704: The first device receives the sixth signal.

[0363] The sixth signal includes the echo signal of the first signal and / or the first signal, or the sixth signal includes the echo signal of the fifth signal and / or the fifth signal. Figure 7 illustrates an example where the sixth signal includes the echo signal of the first signal, or includes the echo signal of the fifth signal. The echo signal of the first signal can be referred to in the description of S304, and will not be repeated here.

[0364] Optionally, the echo signal of the fifth signal may be the echo signal reflected by the target; or the echo signal of the fifth signal may include the echo signal reflected by the target and the echo signal reflected by other tangible objects in the environment where the target is located; or the echo signal of the fifth signal may be a sum of the echo signal reflected by the target and the echo signal reflected by other tangible objects in the environment where the target is located. For ease of understanding, the following description uses the example of the echo signal of the fifth signal being reflected by the target.

[0365] As an example, the sixth signal may be an echo signal of the first signal, or it may be an echo signal of the fifth signal. For example, the first device transmits the first signal and receives an echo signal reflected from the target, i.e., receives the sixth signal, which is an echo signal of the first signal. Optionally, if the fifth signal is a sub-signal of the first signal, the echo signal of the first signal may include the echo signal of the fifth signal. As another example, the first device transmits a fifth signal, which is used for sensing or for sensing and communication; and receives an echo signal reflected from the target, i.e., receives the sixth signal, which is an echo signal of the fifth signal.

[0366] As another example, the sixth signal can be the first signal, or the sixth signal can be the fifth signal. For example, the first device sends a first signal that is received directly by the first device without being reflected by a target, i.e., it receives the sixth signal, which is the first signal. As another example, the first device sends a fifth signal used for sensing or for sensing and communication, and this fifth signal is received directly by the first device without being reflected by a target, i.e., it receives the sixth signal, which is the fifth signal.

[0367] As another example, the sixth signal may include the first signal and its echo, or the sixth signal may include the fifth signal and its echo. For example, the first device transmits the first signal and receives an echo signal reflected by a target and a first signal not reflected by the target, i.e., receives the sixth signal, which includes the echo signal of the first signal and the first signal, or the sixth signal is a sum of the echo signal of the first signal and the first signal. As another example, the first device transmits a fifth signal for sensing or for sensing and communication; and receives an echo signal reflected by a target and a fifth signal not reflected by the target, i.e., receives the sixth signal, which includes the echo signal of the fifth signal and the fifth signal, or the sixth signal is a sum of the echo signal of the fifth signal and the fifth signal.

[0368] Optionally, the first device receives the sixth signal and can perform corresponding processing based on the sixth signal, such as acquiring sensing data based on the sixth signal. This application does not limit this.

[0369] S705: The second device receives the seventh signal.

[0370] The seventh signal includes the echo signal of the first signal and / or the first signal, or the seventh signal includes the echo signal of the fifth signal and / or the fifth signal. Figure 7 illustrates an example where the seventh signal includes the echo signal of the first signal, or the seventh signal includes the echo signal of the fifth signal. Furthermore, the echo signals of the first and fifth signals can be referred to in the description of S704, and will not be repeated here.

[0371] As an example, the seventh signal may be an echo signal of the first signal, or it may be an echo signal of the fifth signal. For example, a first device transmits a first signal; correspondingly, a second device receives the echo signal reflected by the target, i.e., receives the seventh signal, which is an echo signal of the first signal. Optionally, if the fifth signal is a sub-signal of the first signal, the echo signal of the first signal may include the echo signal of the fifth signal. As another example, a first device transmits a fifth signal, which is used for sensing or for sensing and communication; correspondingly, a second device receives the echo signal reflected by the target, i.e., receives the seventh signal, which is an echo signal of the fifth signal.

[0372] As another example, the seventh signal can be the first signal, or it can be the fifth signal. For instance, the first device sends a first signal that is received directly by the second device without being reflected by a target; that is, the second device receives the seventh signal, which is the first signal. As another example, the first device sends a fifth signal used for sensing or for sensing and communication; this fifth signal is received directly by the second device without being reflected by a target; that is, the second device receives the seventh signal, which is the fifth signal. Yet another example, the first device sends a fifth signal used only for communication; accordingly, the second device receives the seventh signal, which is the fifth signal.

[0373] As another example, the seventh signal may include the first signal and its echo, or the seventh signal may include the fifth signal and its echo. For example, a first device transmits a first signal; a second device receives an echo signal reflected by a target and a first signal not reflected by the target, i.e., receives a seventh signal, which includes the echo signal of the first signal and the first signal, or the seventh signal is a sum of the echo signal of the first signal and the first signal. As another example, a first device transmits a fifth signal used for sensing or for sensing and communication; a second device receives an echo signal reflected by a target and a fifth signal not reflected by the target, i.e., receives a seventh signal, which includes the echo signal of the fifth signal and the fifth signal, or the seventh signal is a sum of the echo signal of the fifth signal and the fifth signal.

[0374] In one optional implementation, the second device may determine the frequency domain resources occupied by the first signal (i.e., the first frequency domain resources), and / or, the second device may determine the frequency domain resources occupied by the fifth signal. The first frequency domain resources belong to a first bandwidth. The frequency domain resources occupied by the fifth signal belong to a second bandwidth. Optionally, the first frequency domain resources include the frequency domain resources occupied by the fifth signal. For specific implementation details, please refer to the relevant description in S703, which will not be repeated here. Optionally, the frequency domain resources occupied by the fifth signal may be first sub-frequency domain resources, and correspondingly, the fifth signal is the second signal.

[0375] Optionally, the second device receives the seventh signal and can perform corresponding processing based on the seventh signal, such as acquiring sensing data based on the seventh signal. This application does not limit this.

[0376] In the second sensing method described above, the sensing signal is carried by a first bandwidth, and the communication signal is carried by a second bandwidth. The first bandwidth includes the second bandwidth, thus realizing the design of sensing and communication resources. Furthermore, the fact that the first bandwidth includes the second bandwidth means that the first bandwidth can transmit both sensing and communication signals, saving signaling overhead and increasing spectral efficiency. Additionally, if the second bandwidth is a portion of the frequency domain resources within the first bandwidth, the frequency domain resources occupied by the sensing signal are greater than those occupied by the communication signal, allowing the sensing signal to be transmitted over a wider bandwidth. Generally, a wider bandwidth results in better sensing performance. Therefore, the second sensing method described above can also improve sensing performance, such as increasing ranging accuracy.

[0377] Optionally, the first or second sensing method described above may further include: during or while performing sensing, the first device and / or the second device may stop the timing of the first inactivity timer; or, during or while performing sensing, the third device may not configure the first inactivity timer; or, during or while performing sensing, the third device may configure the value of the first inactivity timer to positive infinity. The first inactivity timer may include a sensing BWP inactivity timer and / or a communication BWP inactivity timer. For example, the first inactivity timer may be an inactivity timer corresponding to a first bandwidth, and when the first inactivity timer expires, it may switch from the active first bandwidth to the initial bandwidth or the default bandwidth. As another example, the first inactivity timer may be an inactivity timer corresponding to a second bandwidth, and when the first inactivity timer expires, it may switch from the active second bandwidth to the initial communication bandwidth or the default communication bandwidth. In this embodiment, during or while performing sensing, by stopping the timing of the first inactive timer, not configuring the first inactive timer, or configuring the value of the first inactive timer to positive infinity, it is not necessary to switch to the initial bandwidth or default bandwidth during or while performing sensing. This allows the sensing signal to be transmitted in the active bandwidth. Typically, the active bandwidth is greater than the initial bandwidth or default bandwidth, and the wider the bandwidth, the better the sensing performance. Thus, this embodiment can improve sensing performance, such as improving ranging accuracy.

[0378] The term "performing sensing" can be understood as: sending sensing signals, receiving sensing signals, within the sending period of sensing signals, running sensing services, running sensing processes, within the coherent processing time corresponding to the sensing signals, or within the estimated duration required to perform sensing. This application does not limit this. "Performing sensing" can be understood as: when sending sensing signals, when performing corresponding processing based on sensing signals, when executing sensing services, or when allowing sensing processes.

[0379] The first and second sensing methods described above can be used independently or in combination. The following will introduce them in conjunction with Figures 9 and 10.

[0380] Figure 9 is a flowchart illustrating the third sensing method provided in this embodiment. This third sensing method can also be called a third integrated communication and sensing method, or a third integrated sensing method. In this embodiment, the first device adopts a single-station sensing mode, and the third device is any device other than the first device. As shown in Figure 9, the method includes the following:

[0381] S901: The third device sends a first message to the first device; correspondingly, the first device receives the first message from the third device.

[0382] The first message can be used to indicate a first bandwidth and / or a second bandwidth. The first bandwidth is used to carry sensing signals. The second bandwidth is used to carry sensing signals and / or communication signals. The first bandwidth includes the second bandwidth. The first message may be carried in the second bandwidth, or the first message may be carried only in the second bandwidth, or the first message may not be carried in frequency domain resources other than the second bandwidth.

[0383] The first bandwidth, the second bandwidth, and the first message can be referred to in the description in S701, and will not be repeated here.

[0384] It should be understood that if the third device and the first device are the same device, S901 is also stated as: the third device (or the first device) determines the first bandwidth and / or the second bandwidth.

[0385] S902: The third device sends a second message to the first device; correspondingly, the first device receives the second message from the third device.

[0386] The second message can be used to indicate a first frequency domain resource and / or a first sub-frequency domain resource. The first frequency domain resource belongs to a first bandwidth. The first frequency domain resource is used to carry a first signal, which is a sensing signal. The first sub-frequency domain resource belongs to a second bandwidth. The first sub-frequency domain resource is used to carry a second signal, which is a communication signal. The first frequency domain resource includes the first sub-frequency domain resource. Optionally, the second signal can be replaced by a fifth signal.

[0387] The second message may be carried in the second bandwidth, or the second message may be carried only in the second bandwidth, or the second message may not be carried in frequency domain resources other than the second bandwidth.

[0388] The first signal, second signal, fifth signal, first frequency domain resource, first sub-frequency domain resource, and second message can be referred to the relevant descriptions in the first and second sensing methods mentioned above, and will not be repeated here.

[0389] It should be understood that if the third device and the first device are the same device, S902 can also be expressed as: the third device (or the first device) determines the first frequency domain resources and / or the first sub-frequency domain resources.

[0390] S903: The first device stops the timing of the first inactive timer.

[0391] S903 is an optional step, indicated by a dashed line in Figure 9. For example, the third device may not configure the first inactive timer, or may configure the value of the first inactive timer to positive infinity. The first inactive timer is described in the foregoing related descriptions and will not be repeated here.

[0392] S904: The first device sends a first signal, or the first device sends a second signal.

[0393] The first signal is carried by a first frequency domain resource, such as when the first device transmits the first signal on the first frequency domain resource. The second signal is carried by a first sub-frequency domain resource, such as when the first device transmits the second signal on the first sub-frequency domain resource. Optionally, the second signal can be replaced by a fifth signal.

[0394] For details on the implementation of S904, please refer to the descriptions of S303 and S703; they will not be repeated here.

[0395] S905: The first device receives the third signal.

[0396] The third signal includes the first signal and / or the echo signal of the first signal, or the third signal includes the second signal and / or the echo signal of the second signal. Optionally, if the second signal is the fifth signal, the third signal can be the seventh signal. Figure 9 illustrates an example where the third signal includes the echo signal of the first signal, or the third signal includes the echo signal of the second signal.

[0397] For details on the implementation of S905, please refer to the descriptions of S304 and S704; they will not be repeated here.

[0398] It is understood that the execution order of the steps in Figure 9 is merely an example, and this application does not limit it. For example, the first device may stop the timing of the first inactive timer after receiving the second message, or it may stop the timing of the first inactive timer before receiving the second message.

[0399] Figure 10 is a flowchart illustrating the fourth sensing method provided in this application embodiment. This fourth sensing method can also be called the fourth integrated communication and sensing method, or the fourth integrated sensing method. In this embodiment, the first device adopts a dual-station sensing mode, and the third device is a device other than the first and second devices. As shown in Figure 10, the method includes the following:

[0400] S1001: The third device sends a first message to the first device; correspondingly, the first device receives the first message from the third device.

[0401] The first message can be used to indicate a first bandwidth and / or a second bandwidth. The first bandwidth is used to carry sensing signals.

The first message may be carried in the second bandwidth, or the first message may be carried only in the second bandwidth, or the first message may not be carried in frequency domain resources other than the second bandwidth.

[0402] The first bandwidth, the second bandwidth, and the first message can be referred to in the description in S701, and will not be repeated here.

[0403] It should be understood that if the third device and the first device are the same device, S1001 can also be expressed as: the third device (or the first device) determines the first bandwidth and / or the second bandwidth.

[0404] S1002: The third device sends a first message to the second device; correspondingly, the second device receives the first message from the third device.

[0406] It should be understood that if the third device and the second device are the same device, S1002 can also be expressed as: the third device (or the second device) determines the first bandwidth and / or the second bandwidth.

[0407] S1003: The third device sends a second message to the first device; correspondingly, the first device receives the second message from the third device.

[0409] The second message may be carried in the second bandwidth, or the second message may be carried only in the second bandwidth, or the second message may not be carried in frequency domain resources other than the second bandwidth.

[0410] The first signal, second signal, fifth signal, first frequency domain resource, first sub-frequency domain resource, and second message can be referred to the relevant descriptions in the first and second sensing methods mentioned above, and will not be repeated here.

[0411] It should be understood that if the third device and the first device are the same device, S1003 can also be expressed as: the third device (or the first device) determines the first frequency domain resources and / or the first sub-frequency domain resources.

[0412] S1004: The third device sends a second message to the second device; correspondingly, the second device receives the second message from the third device.

[0413] The implementation method of S1004 can be referred to the description of S1001, and will not be repeated here.

[0414] It should be understood that if the third device and the second device are the same device, S1004 can also be expressed as: the third device (or the second device) determines the first frequency domain resources and / or the first sub-frequency domain resources.

[0415] S1005: The first device and / or the second device stop the timing of the first inactive timer.

[0416] Step S1005 is optional and is represented by a dashed line in Figure 10. For example, the third device may not configure the first inactive timer, or the value of the first inactive timer may be configured to positive infinity. The first inactive timer is described in the foregoing related descriptions and will not be repeated here.

[0417] S1006: The first device sends a first signal, or the first device sends a second signal.

[0418] The first signal is carried by a first frequency domain resource, such as when the first device transmits the first signal on the first frequency domain resource. The second signal is carried by a first sub-frequency domain resource, such as when the first device transmits the second signal on the first sub-frequency domain resource. Optionally, the second signal can be replaced by a fifth signal.

Figure 10 illustrates an example where the fourth signal includes the echo signal of the first signal, or the fourth signal includes the echo signal of the second signal.

[0422] For the implementation of S1007, please refer to the descriptions of S305 and S705, which will not be repeated here.

[0423] It is understood that the execution order of the steps in Figure 10 is merely an example, and this application does not limit it. For example, the first device may stop the timing of the first inactive timer after receiving the second message, or it may stop the timing of the first inactive timer before receiving the second message. As another example, the third device may send the first message to the first device first, and then send the first message to the second device; or, the third device may send the first message to the second device first, and then send the first message to the first device. As yet another example, the third device may send the second message to the first device first, and then send the second message to the second device; or, the third device may send the second message to the second device first, and then send the second message to the first device.

[0424] This application also provides a communication method and apparatus to avoid wasting the processing power of devices. This communication method and apparatus may not have sensing capabilities. The communication method and apparatus provided in this application relate to the field of communication technology.

[0425] In a communication system, the number of activated measurement resources and / or activated Channel State Information Reference Signal (CSI-RS) ports are indicators related to the processing capacity of the terminal equipment. The terminal equipment performs measurements within the specified number of activated measurement resources and / or activated CSI-RS ports. The terminal equipment can report the number of activated measurement resources and / or activated CSI-RS ports to the network. Therefore, when configuring or activating the terminal equipment for measurement and / or measurement reporting, the network must meet the requirements for the number of activated measurement resources and / or activated CSI-RS ports.

[0426] When a measurement resource is associated with N channel state information (CSI) reports, it is calculated N times when calculating the number of active measurement resources and / or active CSI-RS ports, thus occupying N calculation slots for these operations. However, this repeated occupation of active measurement resources and / or active CSI-RS ports leads to a waste of processing power in the terminal device.

[0427] To address the above problems, this application proposes the following communication method and communication device.

[0428] First, let's introduce some basic concepts.

[0429] 1. CSI report configuration

[0430] The terminal device reports the measurement results according to the CSI report configuration.

[0431] CSI report configuration is defined by a combination of one or more of the following parameters: report configuration identifier (reportConfigID), measurement resource parameters, report type parameters, measurement quantity parameters, codebook parameters, and Channel Quality Indicator (CQI) table parameters.

[0432] The measurement resource parameters indicate the corresponding measurement resources configured in the CSI report. Measurement resources can be one or more combinations of the following: channel measurement resources and interference measurement resources. Interference measurement resources include, for example, CSI interference measurement (CSI-IM) resources for measuring interference and / or non-zero-power CSI-RS (NZP CSI-RS) resources for measuring interference.

[0433] The report type parameter indicates whether the CSI report is a periodic report, a semi-persistent report, or an aperiodic report. This may further include information for configuring the period length and / or time-domain offset of periodic and semi-persistent CSI reports.

[0434] During wireless communication, the specific process by which network devices (such as transmission reception points (TRPs)) obtain CSI report configurations is as follows.

[0435] Network devices configure CSI measurement-related reporting configurations through the information element (IE) CSI-ReportConfig. An example of CSI-ReportConfig is as follows:

[0436] Here, CSI-ReportConfig includes the following parameters:

[0437] 1. reportConfigId is used to identify the ID of CSI-ReportConfig;

[0438] 2. `resourcesForChannelMeasurement` indicates the resources associated with channel measurement (such as CSI-RS, SSB, etc.).

[0439] 3. csi-IM-ResourcesForInterference is used to indicate CSI-IM resources for measurement interference.

[0440] 4. nzp-CSI-RS-ResourcesForInterference is used to indicate NZP CSI-RS resources for measurement interference.

[0441] 5. `reportConfigType` indicates the period of the CSI report, which can be periodic, semi-continuous, or aperiodic. `reportSlotConfig` is used to configure the period and / or offset of periodic and semi-continuous CSI reports.

[0442] 6. `reportQuantity` indicates the content of the CSI measurement, including one or more of the following: precoding matrix indication (PMI) information, channel quality indication (CQI) information, rank indication (RI) information, and layer indication (LI) information. It can be `cri-RI-PMI-CQI`, meaning the UE measures and reports CRI, RI, PMI, and CQI; or it can be `cri-RI-CQI`, meaning the UE measures and reports CRI, RI, and CQI.

[0443] 7. `timeRestrictionForChannelMeasurements` indicates whether time-domain filtering is required for channel measurements in CSI measurements.

[0444] 8. `timeRestrictionForInterferenceMeasurements` indicates whether time-domain filtering is required for interference measurement resources in CSI measurements.

[0445] 9. codebookConfig is used to indicate the codebook type for CSI measurements, including type 1 Single panel, type 1 multi panel, type II, Enhanced type II codebook, etc.

[0446] 10. cqi-Table is used to indicate the form used in CQI measurement reports.

[0447] Network devices transmit channel state sounding signals on reference signal resources. For example, in NR, the channel state sounding signal can be NZP CSI-RS.

[0448] The UE receives channel state sounding signals on pre-configured reference signal resources to perform channel estimation. Furthermore, the TRP configures a set of interference measurement resources corresponding to the reference signal resources for the UE. Each reference signal resource is associated with one interference measurement resource. The UE receives signals on these pre-configured interference measurement resources and performs interference measurements. Based on the channel measurement results obtained on one reference signal resource and the interference measurement results obtained on one associated interference measurement resource, the UE calculates one CSI. When the configured set of reference signal resources includes multiple reference signal resources, the UE can calculate multiple CSIs on these multiple reference signal resources and their associated multiple interference measurement resources. The UE selects one CSI to form a CSI report and sends the CSI report to the TRP via the uplink channel.

[0449] Furthermore, network devices can perform scheduling based on the CSI reports fed back by each UE, for example, sending downlink data to the UE on the PDSCH.

[0450] It should be noted that in the NR protocol, the network device configures reference signal resources and interference measurement resources for the UE. The UE performs corresponding channel measurements and interference measurements based on the signals on the reference signal resources and the signals on the interference measurement resources, respectively. However, for the sake of simplicity, the above process is simplified to the following description in this embodiment: the UE performs CSI measurements on the reference signal resources and interference measurement resources.

[0451] 2. Active CSI-RS resource

[0452] The UE reports its capabilities, determining the number of active measurement resources and / or the number of active CSI-RS ports. If the UE reports 8 supported active CSI-RS resources, the base station cannot configure more than 8 active CSI-RS resources. If the UE reports 64 supported active CSI-RS ports, the base station cannot configure more than 64 active CSI-RS ports.

[0453] The current protocol stipulates that when a CSI-RS resource is associated with N CSI reports, the CSI-RS resource needs to be calculated N times when calculating the active CSI-RS resource. That is, when a CSI-RS resource is associated with N CSI reports, it occupies N active CSI-RS resources.

[0454] Furthermore, existing protocols specify periodic CSI-RS resources, which remain active from the time the periodic CSI-RS resource is configured by the higher layer until the periodic CSI-RS resource configuration is released; for semi-persistent CSI-RS resources, these resources remain active from the time the UE receives the activation command until the UE receives the deactivation command; for non-periodic CSI-RS resources, these resources are active from the time the physical downlink control channel (PDCCH) is received until the end of the CSI report associated with the resource.

[0455] The communication method proposed in this application is described in detail below.

[0456] This application provides a communication method applicable to a terminal device. The method includes: receiving first information and second information, wherein the first information is used to indicate a first CSI report configuration and the second information is used to indicate a second CSI report configuration; the measurement resources corresponding to the first CSI report configuration and the measurement resources corresponding to the second CSI report configuration are the same, wherein the first CSI report configuration and the second CSI report configuration are associated, and the measurement resources corresponding to the first CSI report configuration and the measurement resources corresponding to the second CSI report configuration do not duplicate the number of activated measurement resources and / or the number of activated CSI-RS ports.

[0457] Accordingly, this application provides a communication method that can be applied to a network device. The method includes: sending first information and second information, wherein the first information is used to indicate a first CSI report configuration, and the second information is used to indicate a second CSI report configuration, wherein the measurement resources corresponding to the first CSI report configuration are the same as the measurement resources corresponding to the second CSI report configuration; wherein the first CSI report configuration and the second CSI report configuration are associated, and the measurement resources corresponding to the first CSI report configuration and the measurement resources corresponding to the second CSI report configuration do not duplicate the number of activated measurement resources and / or the number of activated CSI-RS ports.

[0458] According to this solution, based on the relationship between the first and second CSI report configurations, the number of active measurement resources and / or active CSI-RS ports corresponding to the first and second CSI report configurations can be determined to avoid duplicate usage of the same measurement resources in different CSI report configurations. This avoids duplicate usage of the same number of active measurement resources and / or active CSI-RS ports when the same measurement resources are associated with different CSI report configurations.

[0459] One possible implementation is that the first information includes one or more of the following parameters of the first CSI report configuration: report configuration identifier, measurement resource parameter, report type parameter, measurement quantity parameter, codebook parameter, and CQI table parameter. Another possible implementation is that the second information includes one or more of the following parameters of the second CSI report configuration: report configuration identifier, measurement resource parameter, report type parameter, measurement quantity parameter, codebook parameter, and CQI table parameter.

[0460] The first and second information can be carried in the same signaling or in different signaling.

[0461] Another possible implementation is that the second CSI report configuration does not include measurement resources, and / or the measurement resources configured in the second CSI report configuration are the same as those configured in the first CSI report configuration. The second CSI report configuration not including measurement resources can be understood as the measurement resources associated with the second CSI report configuration being the same as those associated with the first CSI report configuration by default, and the resource IDs associated with the first and second CSI report configurations being the same. When counting or calculating the number of activated measurement resources and / or the number of activated CSI-RS ports, the resources configured in the first and second CSI report configurations constitute a set of resources.

[0462] One way to implement the above association is to include a first field in the second information, whereby the first field indicates the association between the first CSI report configuration and the second CSI report configuration. The first field may be, for example, an identifier for the first CSI report configuration, or information indicating the first CSI report configuration. Alternatively, the association may involve the second field included in the second information and the second field included in the first information having the same value. The second field may be, for example, a specific identifier or a specific field.

[0463] In this way, the correlation between the first CSI report configuration and the second CSI report configuration can be directly determined through the displayed instructions, avoiding complex judgment methods.

[0464] When the above-mentioned relationship exists, the first CSI report configuration and the second CSI report configuration must also satisfy the following: the parameters in the first parameter type set of the first CSI report configuration and the second CSI report configuration are the same.

[0465] Optionally, the first parameter type set includes one or more of the following parameter types: measurement resource parameters, measurement quantity parameters, codebook parameters, and CQI table parameters; or,

[0466] The first parameter type set includes all of the following parameter types: measurement resource parameters, measurement quantity parameters, codebook parameters, and CQI table parameters; or,

[0467] The first parameter type set includes parameter types other than the following: reportConfigID, report type parameters; or,

[0468] The first parameter type set includes other parameter types besides the following: report type parameters.

[0469] It can be understood that "parameters are the same" means parameters of the same type are the same. For example, if the measurement resource parameters indicate channel measurement resources and interference measurement resources, then "measurement resource parameters are the same" means that both channel measurement resources and interference measurement resources are the same.

[0470] Thus, the limitation is that only when the parameters of the first CSI report configuration and the second CSI report configuration are the same in the first parameter type set can the number of activated measurement resources and / or activated CSI-RS ports be avoided. This is because when the parameters in the first parameter type set are different, the terminal device needs to perform different signal processing or calculations for the reported content of the first CSI report configuration and the second CSI report configuration, consuming more of the terminal device's computing power. Conversely, when the parameters in the first parameter type set are the same, the terminal device can report the same content for the first CSI report configuration and the second CSI report configuration. For example, the content reported for the first CSI report configuration can be reported again for the second CSI report configuration, without consuming more of the terminal device's computing power. This limitation in this application can prevent network configuration or triggered measurements from exceeding the terminal device's processing capacity.

[0471] Furthermore, the first information may include parameters from the first parameter type set configured in the first CSI report. The parameters from the first parameter type set configured in the second CSI report may refer to the parameters from the first parameter type set included in the first information. The second information may not include parameters from the first parameter type set. This saves signaling resources.

[0472] The following is a specific embodiment provided by this application based on the above communication method.

[0473] The UE receives first CSI report configuration information (CSI-Reportconfig1) and second CSI report configuration information (CSI-Reportconfig2). The first and second CSI report configuration information include one or more of the following: reportConfigID, channel measurement resources, interference measurement resources, reporting period, reported measurement quantity, codebook, and CQI table. The second CSI report configuration information also includes associated report configuration information, such as associatedReportConfigID. The associated report configuration information indicates that the second report configuration information is associated with the first report configuration information. When the second report configuration information is associated with the first report configuration information, one or more of the following conditions are met:

[0474] ● The CSI measurements associated with the second report configuration information do not consume CSI-RS activation resources or the CSI-RS activation port.

[0475] ●One or more of the following in the second report configuration information may not be configured: reportConfigID, channel measurement resources, interference measurement resources, reporting period, reported measurement quantity, codebook, and CQI table. Refer to the configuration in the first report configuration information.

[0476] ●One or more of the following in the second report configuration information are the same as those in the first report configuration information: reportConfigID, channel measurement resources, interference measurement resources, reporting period, reported measurement quantity, codebook, and CQI table.

[0477] Another way to implement the above-mentioned relationship is to satisfy the following condition for the first CSI report configuration and the second CSI report configuration: the parameters in the first parameter type set of the first CSI report configuration and the second CSI report configuration are the same.

[0478] Optionally, the first parameter type set includes one or more of the following parameter types: measurement resource parameters, measurement quantity parameters, codebook parameters, and CQI table parameters; or,

[0479] The first parameter type set includes all of the following parameter types: measurement resource parameters, measurement quantity parameters, codebook parameters, and CQI table parameters; or,

[0480] The first parameter type set includes parameter types other than the following: reportConfigID, report type parameters; or,

[0481] The first parameter type set includes other parameter types besides the following: report type parameters.

[0482] Thus, the limitation is that only when the parameters of the first CSI report configuration and the second CSI report configuration are the same in the first parameter type set can the number of activated measurement resources and / or activated CSI-RS ports be avoided. This is because when the parameters in the first parameter type set are different, the terminal device needs to perform different signal processing or calculations for the reported content of the first CSI report configuration and the second CSI report configuration, consuming more of the terminal device's computing power. Conversely, when the parameters in the first parameter type set are the same, the terminal device can report the same content for the first CSI report configuration and the second CSI report configuration. For example, the content reported for the first CSI report configuration can be reported again for the second CSI report configuration, without consuming more of the terminal device's computing power. This limitation in this application can prevent network configuration or triggered measurements from exceeding the terminal device's processing capacity.

[0483] This application provides another communication method that can be applied to a terminal device. The method includes: receiving third information, the third information being used to indicate a first CSI report configuration and a second CSI report configuration, wherein the measurement resources corresponding to the first CSI report configuration are the same as the measurement resources corresponding to the second CSI report configuration; wherein the measurement resources corresponding to the first CSI report configuration and the measurement resources corresponding to the second CSI report configuration do not repeatedly occupy the number of activated measurement resources and / or the number of activated CSI-RS ports, or it can be stated that the measurement resources corresponding to the third information do not repeatedly occupy the number of activated measurement resources and / or the number of activated CSI-RS ports, or it can be stated that when counting or calculating the number of activated measurement resources and / or the number of activated CSI-RS ports, the resources configured in the first CSI report configuration and the resources configured in the second CSI report configuration constitute a set of resources.

[0484] Accordingly, this application provides a communication method that can be applied to a network device. The method includes: sending third information, which indicates a first CSI report configuration and a second CSI report configuration, wherein the measurement resources corresponding to the first CSI report configuration are the same as the measurement resources corresponding to the second CSI report configuration; wherein the measurement resources corresponding to the first CSI report configuration and the measurement resources corresponding to the second CSI report configuration do not repeatedly occupy the number of activated measurement resources and / or the number of activated CSI-RS ports, or expressed as the measurement resources corresponding to the third information do not repeatedly occupy the number of activated measurement resources and / or the number of activated CSI-RS ports.

[0485] According to this solution, a third piece of information (such as an information element IE, or information corresponding to the same CSI report configuration identifier) ​​can be used to instruct the first CSI report configuration and the second CSI report configuration to ensure that the measurement resources corresponding to the first CSI report configuration and the measurement resources corresponding to the second CSI report configuration do not duplicate the number of activated measurement resources and / or activated CSI-RS ports. This avoids duplicate occupation of the number of activated measurement resources and / or activated CSI-RS ports when the same measurement resources are associated with different CSI report configurations.

[0486] One possible implementation is that the third information includes parameters from the second parameter type set. The parameters in the second parameter type set are parameters configured in both the first and second CSI reports. For example, the second parameter type set includes one or more of the following parameters: report configuration identifier, measurement resource parameters, measurement quantity parameters, codebook parameters, and CQI table parameters.

[0487] One possible implementation is that the third information further includes a first parameter of a first parameter type and a second parameter of the same type. The first parameter is a parameter configured for a first CSI report, and the second parameter is a parameter configured for a second CSI report. For example, the first parameter type is a report type parameter. The first parameter may indicate that the report type parameter configured for the first CSI report is a periodic report, and the second parameter may indicate that the report type parameter configured for the second CSI report is a non-periodic report.

[0488] In this way, the first CSI report configuration and the second CSI report configuration can share some parameter indication information to save signaling resources.

[0489] In this embodiment, if the parameters corresponding to any parameter type in the CSI report configuration are different, they are considered different CSI report configurations. For example, a CSI report configuration with a report type parameter indicating periodic reporting is different from a CSI report configuration with a report type parameter indicating non-periodic reporting. As another example, a CSI report configuration with a report type parameter indicating periodic reporting but different corresponding period lengths or time-domain offsets is also considered a different CSI report configuration.

[0490] Furthermore, the first CSI report configuration and the second CSI report configuration must also satisfy the following: the parameters in the first parameter type set of the first CSI report configuration and the second CSI report configuration are the same.

[0491] Optionally, the first parameter type set includes one or more of the following parameter types: measurement resource parameters, measurement quantity parameters, codebook parameters, and CQI table parameters; or,

[0492] The first parameter type set includes all of the following parameter types: measurement resource parameters, measurement quantity parameters, codebook parameters, and CQI table parameters; or,

[0493] The first parameter type set includes parameter types other than the following: reportConfigID, report type parameters; or,

[0494] The first parameter type set includes other parameter types besides the following: report type parameters.

[0495] It can be understood that "parameters are the same" means parameters of the same type are the same. For example, if the measurement resource parameters indicate channel measurement resources and interference measurement resources, then "measurement resource parameters are the same" means that both channel measurement resources and interference measurement resources are the same.

[0496] Optionally, the first parameter type set and the second parameter type set are the same parameter type set.

[0497] Thus, the limitation is that only when the parameters of the first CSI report configuration and the second CSI report configuration are the same in the first parameter type set can the number of activated measurement resources and / or activated CSI-RS ports be avoided. This is because when the parameters in the first parameter type set are different, the terminal device needs to perform different signal processing or calculations for the reported content of the first CSI report configuration and the second CSI report configuration, consuming more of the terminal device's computing power. Conversely, when the parameters in the first parameter type set are the same, the terminal device can report the same content for the first CSI report configuration and the second CSI report configuration. For example, the content reported for the first CSI report configuration can be reported again for the second CSI report configuration, without consuming more of the terminal device's computing power. This limitation in this application can prevent network configuration or triggered measurements from exceeding the terminal device's processing capacity.

[0498] The following is a specific embodiment provided by this application based on the above communication method.

[0499] The UE receives the first CSI report configuration information (CSI-Reportconfig1), which includes one or more of the following: reportConfigID, channel measurement resources, interference measurement resources, CSI report period, CSI report measurement quantity, codebook, and CQI table. The report period can be configured as one or more of the following: periodic, semi-persistent, aperiodic, {periodic and aperiodic CSI reports}, {semi-persistent and aperiodic CSI reports}, and {periodic and semi-persistent CSI reports}.

[0500] {Periodic and Aperiodic CSI Reports} refers to base stations triggering aperiodic CSI reports via DCI, in addition to periodic CSI reports. Periodic and aperiodic CSI reports share one or more of the same information, including reportConfigID, channel measurement resources, interference measurement resources, CSI report measurements, codebook, and CQI table. Optionally, periodic and aperiodic CSI reports do not duplicate the use of active CSI-RS resources and active CSI-RS ports.

This function can be implemented in hardware, software, or by hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the above functions.

This sensing device can also be called a communication-sensing integrated device, or a sensing-communication integrated device; or it can also be called a communication device, etc., and this application does not limit it in this regard.

[0502] Figure 11 illustrates a schematic diagram of a sensing device 1100 provided in an embodiment of this application. This sensing device 1100 can implement the functions or steps performed by the first device or the second device in the various method embodiments described above.

[0511] It should be noted that the sensing device 1100 may include a processing module 1101, but not a transceiver module 1102. Alternatively, the sensing device 1100 may include a transceiver module 1102, but not a processing module 1101.
