Description

Communication methods, electronic devices, and computer storage media

[0001] This application claims priority to Chinese Patent Application No. 202410942115.6, filed on July 15, 2024, entitled "Communication Method, Electronic Device and Computer Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method, electronic device, and computer storage medium. Background Technology

[0003] Communication-sensing integration is a key technology in next-generation wireless communication systems. It aims to integrate wireless communication and sensing functions into a single system, utilizing the various propagation characteristics of wireless signals to achieve sensing functions such as positioning, detection, imaging, and identification of sensing targets, thereby acquiring information about the surrounding physical environment, improving communication performance, and enhancing user experience.

[0004] In integrated communication and sensing technology, the position and velocity of targets in the environment are sensed by measuring the echo signals of the sensed signals. The echo signal is the signal generated when the sensed signal is reflected by the sensed target in the environment. The time delay of the echo signal relative to the sensed signal reflects the distance of the sensed target; the Doppler frequency shift of the echo signal relative to the sensed signal reflects the velocity of the sensed target. When sensing the position and velocity of targets, there are usually certain accuracy requirements, i.e., error requirements, such as distance measurement accuracy and velocity measurement accuracy. How to perform reasonable operations during the sensing and measurement process to meet these accuracy requirements has become a pressing technical problem.

[0005] Summary of the Invention

[0006] The purpose of this application is to provide a communication method, electronic device, and computer storage medium that can meet the sensing accuracy requirements by adjusting the beam direction of the sensing signal, adjusting the transmission power of the sensing signal, and sending a measurement report during the sensing measurement process.

[0007] The aforementioned and other objectives will be achieved through the features described in the independent claims. Further implementations are illustrated in the dependent claims, the specification, and the drawings.

[0008] In a first aspect, a communication method is provided, applied to a first device, comprising:

[0009] At least one echo signal is measured to obtain measurement results corresponding to each of the at least one echo signal, and each of the at least one echo signal corresponds to a different sensing target;

[0010] Based on the measurement results corresponding to the at least one echo signal, perform at least one of the following operations: adjust the beam direction of the transmitted sensing signal; adjust the transmission power of the sensing signal; and send a measurement report to the second device.

[0011] By implementing the method of the first aspect, during the sensing measurement process, at least one operation can be performed based on the measurement results corresponding to the echo signals to adjust the beam pointing of the sensing signal, adjust the transmission power of the sensing signal, and send a measurement report to meet the sensing accuracy requirements.

[0012] In conjunction with the first aspect, in one possible implementation, the step of performing at least one of the following operations based on the measurement results corresponding to the at least one echo signal: adjusting the beam direction of the transmitted sensing signal; adjusting the transmission power of the sensing signal; and sending a measurement report to the second device, including:

[0013] If the measurement results corresponding to the at least one echo signal meet the target conditions, then at least one of the following operations is performed: adjusting the beam direction of the sensing signal; adjusting the transmission power of the sensing signal; and sending a measurement report to the second device.

[0014] By implementing this method, if the measurement results of the echo signal meet the target conditions, the sensing accuracy requirements can be met by adjusting the beam direction of the sensing signal, adjusting the transmission power of the sensing signal, or sending a measurement report, thereby reducing unnecessary operation adjustments or the reporting of measurement reports.

[0015] In conjunction with the first aspect, in one possible implementation, the target condition includes at least one of a first condition, a second condition, a third condition, a fourth condition, or a fifth condition:

[0016] The first condition includes: the difference between the first measurement result and the reference value is greater than or equal to a first threshold;

[0017] The second condition includes: the first measurement result is greater than or equal to the second threshold;

[0018] The third condition includes: the difference between the reference value and the first measurement result is greater than or equal to the third threshold;

[0019] The fourth condition includes: the first measurement result is less than or equal to the fourth threshold;

[0020] The fifth condition includes: the change between the first measurement result and the second measurement result is greater than or equal to the fifth threshold, the second measurement result is the minimum measurement result of the previous cycle, or the second measurement result is the value reported by the first device last time;

[0021] Wherein, the first measurement result is the minimum measurement result among the measurement results corresponding to the at least one echo signal, and the reference value is the expected measurement result of the at least one echo signal.

[0022] Implementing this method provides the target conditions that the echo signal needs to meet, so as to flexibly determine the timing of the operation to be performed and meet certain sensing accuracy requirements.

[0023] In conjunction with the first aspect, in one possible implementation, prior to sending the measurement report to the second device, it further includes:

[0024] The target conditions are determined based on the perception strategy of the first device preference and the perception strategy of the second device preference.

[0025] Wherein, the perception strategy preferred by the first device is one of the resource priority strategy, the power priority strategy, or a compromise strategy, and the perception strategy preferred by the second device is one of the resource priority strategy, the power priority strategy, or a compromise strategy.

[0026] The resource priority strategy indicates that time-frequency resources of the sensing signal should be saved first, the power priority strategy indicates that transmission power of the sensing signal should be saved first, and the compromise strategy indicates that both saving time-frequency resources and saving transmission power of the sensing signal should be considered simultaneously.

[0027] By implementing this method, the target conditions for triggering the sending of measurement reports are determined based on the perception strategy preferred by the first device and the perception strategy preferred by the second device. The conditions included in the target conditions can be flexibly determined, thereby meeting the requirements of various perception strategy scenarios.

[0028] In conjunction with the first aspect, in one possible implementation, if both the perception strategy preferred by the first device and the perception strategy preferred by the second device are power-first strategies, the target condition includes the third condition and / or the fourth condition.

[0029] If both the perception strategy preferred by the first device and the perception strategy preferred by the second device are resource priority strategies, the target condition includes the first condition and / or the second condition.

[0030] If both the perception strategy preferred by the first device and the perception strategy preferred by the second device are compromise strategies, or if the perception strategies preferred by the first device and the perception strategies preferred by the second device are different, the target condition includes at least one of the first condition, the second condition, the third condition, the fourth condition, or the fifth condition.

[0031] By implementing this approach, the combination of conditions contained in the target conditions is determined through a sensing strategy. This allows for scenarios that prioritize saving the transmission power of sensing signals, prioritize saving the time and frequency resources of sensing signals, or simultaneously consider both saving the transmission power and saving the time and frequency resources of sensing signals.

[0032] In conjunction with the first aspect, in one possible implementation, the measurement report indicates at least one of the following values:

[0033] The difference between the first measurement result and the reference value;

[0034] The difference between the first measurement result and the second threshold or the fourth threshold;

[0035] The change between the first measurement result and the second measurement result;

[0036] The average value of the measurement results corresponding to each of the at least one echo signal;

[0037] The first measurement result;

[0038] The difference between the average value of the measurement results corresponding to the at least one echo signal and the first measurement result;

[0039] The measurement results corresponding to each of the at least one echo signal.

[0040] Implementing this method provides various values ​​indicated in the measurement report, which allows network devices to reasonably adjust the transmission power of the sensing signal and / or the time-frequency resources of the sensing signal based on the measurement report.

[0041] In conjunction with the first aspect, in one possible implementation, at least one of the following is indicated by the second device: the reference value, the target condition, the threshold value among the various conditions included in the target condition, the feedback granularity of the value indicated in the measurement report, the reporting unit of the value indicated in the measurement report, and the perception strategy of the second device preference.

[0042] The feedback granularity of the values ​​indicated in the measurement report is one of the following: sensing target, sensing beam, and sensing node.

[0043] If the feedback granularity is a sensing beam, then the measurement report indicates the at least one value corresponding to each sensing beam, and the at least one echo signal is the echo signal corresponding to different sensing targets within the coverage area of ​​the same sensing beam;

[0044] If the feedback granularity is a sensing node, then the measurement report indicates the at least one value corresponding to the first device, and the at least one echo signal is the echo signal corresponding to all sensing targets sensed by the first device;

[0045] If the feedback granularity is a sensing target, then the measurement report indicates the at least one value corresponding to each sensing target;

[0046] The reporting unit of the value indicated in the measurement report is used to determine the reported value corresponding to the indicated value, and the reported value is less than the indicated value.

[0047] By implementing this method, the second device can indicate relevant information in the measurement report feedback, thereby facilitating the first device to report the measurement report.

[0048] In conjunction with the first aspect, in one possible implementation, after sending the measurement report to the second device, the method further includes:

[0049] Receive adjustment information from the second device, the adjustment information being determined by the second device based on the measurement report;

[0050] The adjustment information includes a first indication information and / or a second indication information, wherein the first indication information indicates the adjusted transmission power of the sensing signal, and the second indication information indicates the adjusted time-frequency resources of the sensing signal.

[0051] By implementing this method, the second device can adjust the transmission power of the sensing signal and / or the time-frequency resources of the sensing signal based on the measurement report reported by the first device, thereby ensuring a certain sensing accuracy requirement.

[0052] In conjunction with the first aspect, in one possible implementation, if the measurement results corresponding to the at least one echo signal satisfy the target condition, then at least one of the following operations is performed: adjusting the beam direction of the transmitted sensing signal; adjusting the transmission power of the sensing signal; and sending a measurement report to the second device, including:

[0053] If the measurement results corresponding to the at least one echo signal meet the target conditions, then the transmission power of the sensing signal is adjusted.

[0054] Wherein, adjusting the transmission power of the sensing signal if the measurement results corresponding to the at least one echo signal respectively meet the target conditions includes:

[0055] If the measurement results corresponding to the at least one echo signal meet the target conditions, the transmission power of the sensing signal is adjusted according to the sensing strategy preferred by the first device and the sensing strategy preferred by the second device.

[0056] By implementing this method, when the measurement results of the echo signal meet the target conditions, the transmission power of the sensing signal is further adjusted based on the sensing strategy, thereby satisfying the scenario of prioritizing saving the transmission power of the sensing signal or the scenario of prioritizing saving the time and frequency resources of the sensing signal.

[0057] In conjunction with the first aspect, in one possible implementation, if the measurement results corresponding to the at least one echo signal respectively meet the target conditions, adjusting the transmission power of the sensing signal according to the sensing strategy preferred by the first device and the sensing strategy preferred by the second device includes:

[0058] If the measurement results corresponding to the at least one echo signal satisfy the first condition and / or the second condition, and both the sensing strategy preferred by the first device and the sensing strategy preferred by the second device are power-first strategies, then the transmission power of the sensing signal is reduced; or,

[0059] If the measurement results corresponding to the at least one echo signal satisfy the third condition and / or the fourth condition, and both the sensing strategy preferred by the first device and the sensing strategy preferred by the second device are resource priority strategies, then the transmission power of the sensing signal is increased.

[0060] Implementing this method, when the measurement result corresponding to the echo signal meets the first condition and / or the second condition, does not directly reduce the transmission power of the sensing signal. Instead, it is necessary to determine whether to reduce the transmission power of the sensing signal based on whether both the sensing strategy preferred by the first device and the sensing strategy preferred by the second device are power-priority strategies, thereby satisfying the scenario of prioritizing saving the transmission power of the sensing signal.

[0061] When the measurement result corresponding to the echo signal meets the third and / or fourth conditions, instead of directly increasing the transmission power of the sensing signal, it is necessary to determine whether to increase the transmission power of the sensing signal based on whether both the sensing strategy preferred by the first device and the sensing strategy preferred by the second device are resource priority strategies, so as to meet the scenario of prioritizing the saving of time and frequency resources of the sensing signal.

[0062] In conjunction with the first aspect, in one possible implementation, reducing the transmission power of the sensing signal includes:

[0063] The transmission power of the sensing signal is reduced by a first power step, the first power step being indicated by the second device;

[0064] Increasing the transmission power of the sensing signal includes:

[0065] The transmission power of the sensing signal is increased by a second power step, which is indicated by the second device.

[0066] For example, the first power step size is the same as the second power step size, or the first power step size is different from the second power step size.

[0067] By implementing this method, the transmission power of the sensing signal is reduced or increased according to the power step size, thereby improving the adjustment accuracy of the transmission power of the sensing signal.

[0068] In conjunction with the first aspect, in one possible implementation, the at least one echo signal is an echo signal corresponding to different sensing targets within the coverage area of ​​the first sensing beam, and the first sensing beam is the beam that transmits the sensing signal.

[0069] Based on the measurement results corresponding to the at least one echo signal, perform at least one of the following operations: adjust the beam direction of the transmitted sensing signal; adjust the transmission power of the sensing signal; send a measurement report to the second device, including:

[0070] Based on the measurement results corresponding to the at least one echo signal, the beam direction for transmitting the sensing signal is adjusted.

[0071] The step of adjusting the beam direction of the sensing signal based on the measurement results corresponding to the at least one echo signal includes:

[0072] The optimal beam pointing of the first sensing beam is determined based on the measurement results corresponding to the at least one echo signal and the angle of arrival corresponding to the at least one echo signal.

[0073] The beam pointing of the first sensing beam is adjusted to the optimal beam pointing.

[0074] By implementing this method, the sensing beam that transmits the sensing signal can be adjusted to the optimal beam direction, thereby meeting the sensing accuracy requirements as much as possible and reducing the transmission power, thus reducing power consumption.

[0075] In conjunction with the first aspect, in one possible implementation, the measurement result is a measurement value used to represent the quality of echo signal reception.

[0076] This approach uses measurements related to the quality of the echo signal reception to determine whether to perform the corresponding operation, in order to meet certain sensing accuracy requirements.

[0077] Secondly, a communication method is provided, applied to a second device, comprising:

[0078] Receive measurement reports from the first device;

[0079] Based on the measurement report, adjust the transmission power of the sensing signal and / or adjust the time-frequency resources of the sensing signal.

[0080] In conjunction with the second aspect, in one possible implementation, the measurement report indicates at least one of the following values:

[0081] The difference between the first measurement result and the reference value;

[0082] The difference between the first measurement result and the second or fourth threshold;

[0083] The change between the first and second measurement results;

[0084] The average value of the measurement results corresponding to at least one echo signal;

[0085] First measurement result;

[0086] The difference between the average value of the measurement results corresponding to at least one echo signal and the first measurement result;

[0087] The measurement results corresponding to at least one echo signal;

[0088] Wherein, the first measurement result is the minimum measurement result among the measurement results corresponding to at least one echo signal received by the first device, the reference value is the expected measurement result of the at least one echo signal, the at least one echo signal is the echo signal of the same sensing signal, and the at least one echo signal corresponds to different sensing targets.

[0089] The second measurement result is the minimum measurement result of the previous cycle, or the second measurement result is the value reported by the first device last time.

[0090] In conjunction with the second aspect, in one possible implementation, the method further includes:

[0091] The adjustment information is sent to the first device. The adjustment information includes a first indication information and / or a second indication information. The first indication information indicates the adjusted transmission power of the sensing signal, and the second indication information indicates the adjusted time-frequency resources of the sensing signal.

[0092] The beneficial effects of the second aspect and its various possible implementations can be seen in the first aspect and its various possible implementations.

[0106] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0107] To facilitate understanding, the relevant terms and concepts involved in the embodiments of this application will be introduced below.

[0108] 1. Perception

[0109] Sensing refers to the detection of parameters of a target in the physical environment, such as the target's position and velocity. It can be understood as a radar detection system detecting a target by emitting electromagnetic waves and analyzing the echo signals reflected from the object. The target can be a tangible object in the environment capable of reflecting electromagnetic waves, such as fixed objects like mountains, forests, or buildings. It can also include movable objects such as vehicles, drones, pedestrians, and terminal devices. The target can also be referred to as the perceived target, the object being sensed, the target being detected, the object being sensed, the object being detected, or the device being sensed, etc., and this application does not limit the terminology used in its embodiments. Sensing can also be called detection.

[0110] 2. Sensing signals

[0111] Sensing signals are signals used to sense (or detect) a target (or object). Sensing signals are also called detection signals, linear frequency modulated signals, radar signals, radar sensing signals, radar detection signals, environmental sensing signals, etc. Sensing signals can be pulse signals or signals from wireless communication systems. For example, a sensing signal can be an orthogonal frequency division multiplexing (OFDM) signal obtained by modulating a specific sequence on a subcarrier. This specific sequence can be any of the following sequences: Zadoff-Chu sequence (ZC sequence), pseudo-random sequence, predefined sequence, etc. Pseudo-random sequences include any of the following sequences: longest linear feedback shift register sequence (m-sequence), Gold sequence, etc. Predefined sequences can be, for example, random data symbols modulated by quadrature phase shift keying (QPSK), quadrature amplitude modulation (QAM), etc.

[0112] 3. Echo signal

[0113] An echo signal is a signal generated when a sensed signal is reflected by a sensed target. It can be understood that echo signals can be reflected not only by the sensed target but also by other objects in the environment. The time delay of the echo signal relative to the sensed signal reflects the distance to the sensed target. The Doppler shift of the echo signal relative to the sensed signal reflects the velocity of the sensed target.

[0114] 4. Sensing Beam

[0115] Targets within the coverage area of ​​a sensing beam can be detected by transmitting sensing signals through the sensing beam. One or more targets can exist within the coverage area of ​​the same sensing beam.

[0116] 5. Sensing accuracy

[0117] Sensing accuracy can also be understood as error. For example, sensing accuracy includes at least one of the following: ranging (or time delay) accuracy, velocity (or Doppler) accuracy, angle (azimuth, pitch) accuracy, acceleration (X / Y / Z directions) accuracy, angular velocity (around X / Y / Z axes) accuracy, etc.

[0118] In this embodiment, the sensing accuracy is affected by the quality of the echo signal reception and also by the time-frequency resources of the sensing signal, such as the time-domain interval, frequency-domain interval, the number of time-domain symbols actually occupied by the time-domain resources, and the number of frequency-domain units actually occupied by the frequency-domain resources. The following section uses the calculation of the speed measurement accuracy σ as an example.v As an example, the following formula is the formula for calculating speed measurement accuracy:

[0119] Where Δv is the velocity resolution, and the signal-to-noise ratio (SNR) is the SNR of the echo signal. Δv is calculated using the following formula:

[0120] Where λ is the wavelength, M is the number of sensing symbols, and T is the period of the sensing symbols.

[0121] From Formula 1 above, we can see that σ v A lower SNR results in higher speed measurement accuracy, and increasing the SNR can improve speed measurement accuracy. Increasing the SNR can be achieved by increasing the transmission power of the sensing signal or by allocating more time-frequency resources to the sensing signal. The following example illustrates how allocating more time-frequency resources to the sensing signal to increase SNR involves allocating multiple time-frequency resources to the sensing signal and transmitting the same sensing signal on different time-frequency resources. The sensing node can then coherently combine the echo signals received on these multiple time-frequency resources, thereby increasing the SNR.

[0122] As can be seen from Formulas 1 and 2 above, at a specific SNR, σ can also be reduced by decreasing Δv, which in turn increases the perceptual resolution. v The goal is to reduce and improve speed measurement accuracy. This can be achieved by reducing Δv as shown in Formula 2, for example, by adjusting the sensing symbol period or the number of sensing symbols.

[0123] Figure 1 is a schematic diagram of a communication system architecture applicable to an embodiment of this application. As shown in Figure 1, the communication system architecture may include a first device and a second device. Figure 1 uses a mobile phone as the first device and a base station as the second device for illustration. The first device can also be called a sensing node. This first device can receive echo signals and measure the echo signals to obtain measurement results. Optionally, the first device can send a measurement report to the second device, which indicates relevant information about the measurement results. The sensing signal corresponding to the echo signal can be sent by the second device, as shown in Figure 2A, illustrating a collaborative sensing scenario between the first and second devices. Alternatively, the sensing signal corresponding to the echo signal can be sent by the first device, as shown in Figure 2B, illustrating a self-transmitting and self-receiving sensing scenario by the first device.

Local area networks (WLAN), wireless fidelity (WiFi) systems, next-generation communication systems, or other communication systems. NR systems can also be called fifth-generation mobile networks (5G) communication systems.

[0125] The first device may be, but is not limited to, terminal devices and network devices, and the second device may be, but is not limited to, terminal devices and network devices.

[0126] Network equipment includes, but is not limited to: fifth-generation mobile communication systems (5G). th Next-generation base stations (generation nodeB, gNB) in 5G, and sixth-generation mobile communication systems (6G) thNetwork devices in 6G (6G generation) include base stations, evolved node Bs (eNBs), radio network controllers (RNCs), node Bs (NBs), base station controllers (BSCs), base transceiver stations (BTSs), home base stations (e.g., home evolved node Bs or home node Bs (HNBs), baseband units (BBUs), transmitting and receiving points (TRPs), transmitting points (TPs), and mobile switching centers. Network devices can also be radio controllers, centralized units (CUs), and / or distributed units (DUs) in cloud radio access networks (CRAN) scenarios. Alternatively, network devices can be relay stations, access points, vehicle-mounted equipment, terminal equipment, wearable devices, and network equipment in future mobile communications or future evolved PLMNs. Network devices can also be sensing functions or sensing functional entities. In some embodiments, the network device may also be a means of providing wireless communication capabilities for terminal devices, such as a chip system. For example, a chip system may include a chip, and may also include other discrete components.

It should be noted that terminal equipment can support at least one wireless communication technology, such as Long Term Evolution (LTE) or New Radio (NR). For example, terminal devices can be mobile phones, tablets, desktop computers, laptops, all-in-one computers, in-vehicle terminals, virtual reality (VR) terminals, augmented reality (AR) terminals, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, wearable devices, terminal devices in future mobile communication networks, or terminal devices in future evolved public land mobile networks (PLMNs), etc. In some embodiments of this application, the terminal device may also be a device with transceiver functions, such as a chip system. The chip system may include a chip, and may also include other discrete components.

[0128] The form of network devices and terminal devices is not limited in the embodiments of this application.

[0129] Figure 2A is a schematic diagram of a collaborative sensing scenario provided by an embodiment of this application. In this application scenario, the second device sends a sensing signal, and the first device receives the echo signal generated by the reflection of the sensing signal through a sensing target in the environment (Figure 2A uses a building as an example of a sensing target). In Figure 2A, one sensing target is used as an example, but it can also include multiple sensing targets. One sensing target corresponds to one echo signal. If there are multiple sensing targets, the first device can receive the echo signals corresponding to each of the multiple sensing targets, that is, the first device can receive multiple echo signals. It can be understood that the multiple sensing targets can be sensing targets within the coverage area of ​​the same sensing beam, or they can be sensing targets within the coverage areas of different sensing beams in multiple sensing beams. For example, if four sensing targets need to be sensed, sensing target 1 and sensing target 2 are sensing targets within the coverage area of ​​sensing beam 1, and sensing target 3 and sensing target 4 are sensing targets within the coverage area of ​​sensing beam 2.

[0130] The first device can measure each echo signal and obtain the measurement result corresponding to each echo signal. If the measurement result corresponding to the echo signal meets the target condition, for example, the minimum measurement result among the measurement results corresponding to multiple echo signals is greater than one threshold value or less than another threshold value, a measurement report is sent to the second device. This measurement report indicates relevant information about the measurement result. This allows the second device to adjust the transmission power of the sensing signal and / or adjust the time-frequency resources of the sensing signal according to the measurement report, thereby ensuring that the sensing result meets a certain sensing accuracy.

[0131] Figure 2B is a schematic diagram of a self-transmitting and self-receiving sensing scenario provided by an embodiment of this application. In this application scenario, the first device transmits a sensing signal and receives the echo signal generated by the reflection of the sensing signal from a sensing target in the environment. The first device can sense sensing targets within the coverage area of ​​one sensing beam or multiple sensing beams. As shown in Figure 2B, the first device can sense sensing targets within the coverage areas of two sensing beams, namely sensing beam 1 and sensing beam 2. For example, the first device can transmit sensing signals using sensing beam 1 and sensing beam 2 respectively. Optionally, the first device can transmit sensing signals using sensing beam 1 and sensing beam 2 at different times. The first device can sense vehicles and pedestrians within the coverage area of ​​sensing beam 1, and can sense pedestrians within the coverage area of ​​sensing beam 2. Specifically, the first device uses sensing beam 1 to transmit a sensing signal and receives the echo signals corresponding to vehicles and pedestrians within the coverage area of ​​sensing beam 1. The first device uses sensing beam 2 to send sensing signals and receives echo signals corresponding to pedestrians within the coverage area of ​​sensing beam 2.

[0132] The first device can measure each echo signal to obtain the measurement result corresponding to each echo signal. If the measurement result corresponding to the echo signal meets the target condition, for example, the smallest measurement result among the measurement results corresponding to multiple echo signals is greater than or less than a threshold value, then at least one of the following operations can be performed: adjusting the beam direction of the transmitted sensing signal; adjusting the transmission power of the sensing signal; and sending a measurement report to the second device, which indicates relevant information about the measurement result. This ensures that the sensing result meets a certain sensing accuracy. The multiple echo signals can be echo signals corresponding to sensing targets within the coverage area of ​​a single sensing beam, or they can be echo signals corresponding to different sensing targets within the coverage areas of multiple sensing beams, that is, echo signals of all sensing targets sensed by the first device.

[0133] Please refer to Figure 3, which is a flowchart illustrating a communication method provided in an embodiment of this application. As shown in Figure 3, the communication method of this embodiment includes, but is not limited to, the following steps:

[0134] 301, The first device measures at least one echo signal and obtains the measurement results corresponding to each of the at least one echo signal.

[0135] Each of the at least one echo signal corresponds to a different sensing target.

[0136] In this embodiment, the first device is a sensing node. The first device can measure at least one echo signal to obtain measurement results corresponding to each of the at least one echo signal. The measurement results are measurement values ​​used to represent the quality of echo signal reception; that is, one measurement result corresponds to one echo signal. The measurement results may include, but are not limited to,: Reference Signal Recived Quality (RSRQ), Reference Signal Receiving Power (RSRP), SNR, Signal to Interference plus Noise Ratio (SINR), minimum value, maximum value, average value, etc.

[0137] In this measurement process, the measurement result corresponding to one echo signal is the minimum value. This minimum value can be understood as the minimum of multiple measurements taken by the first device on the target corresponding to the echo signal within one cycle. These measurements can be values ​​such as RSRQ, RSRP, SNR, SINR, etc. The measurement result corresponding to one echo signal is the maximum value. This maximum value can be the maximum of multiple measurements taken by the first device on the target corresponding to the echo signal. Finally, the measurement result corresponding to one echo signal is the average value. This average value can be the average of multiple measurements taken by the first device on the target corresponding to the echo signal.

[0138] For example, the sensing signal corresponding to the at least one echo signal can be sent by a first device, that is, the first device performs self-sensing and self-receiving, such as the self-sensing and self-receiving scenario shown in Figure 2B. For example, the sensing signal corresponding to the at least one echo signal can be sent by a second device, that is, the first device and the second device cooperate in sensing, such as the cooperative sensing scenario shown in Figure 2A.

[0139] In one implementation, the first or second device can use a single sensing beam to transmit sensing signals, meaning that the at least one echo signal is an echo signal reflected from different sensing targets within the coverage area of ​​the same sensing beam. In another implementation, the first or second device can also use multiple sensing beams to transmit sensing signals. For example, as shown in Figure 2B, the first device can use sensing beam 1 and sensing beam 2 respectively to transmit sensing signals, that is, to sense sensing targets within the coverage area of ​​multiple sensing beams. Correspondingly, the aforementioned at least one echo signal is an echo signal reflected from sensing targets within the coverage area of ​​multiple sensing beams.

[0140] 302, the first device performs at least one of the following operations based on the measurement results corresponding to at least one echo signal: adjusting the beam direction of the transmitted sensing signal; adjusting the transmission power of the sensing signal; and sending a measurement report to the second device.

[0141] The measurement report indicates relevant information about the measurement results corresponding to each of the at least one echo signal.

[0142] The first device may perform one or more of the following operations based on the measurement results corresponding to at least one echo signal: adjusting the beam direction of the transmitted sensing signal, adjusting the transmission power of the sensing signal, and sending a measurement report to the second device. For example, the first device may adjust the beam direction of the transmitted sensing signal and the transmission power of the sensing signal based on the measurement results corresponding to at least one echo signal. This application does not limit the combination of operations that can be performed.

[0143] In one implementation, if the sensing signal is transmitted by a first device, such as in the scenario shown in Figure 2B, the first device may perform at least one of the following operations: adjust the beam direction of the transmitted sensing signal; adjust the transmission power of the sensing signal; and send a measurement report to a second device. In another implementation, if the sensing signal is transmitted by a second device, such as in the scenario shown in Figure 2A, the operations that the first device may perform may include sending a measurement report to the second device.

[0144] In some implementations, the first device can perform at least one of the above operations if the measurement results corresponding to at least one echo signal meet the target conditions. Adjusting the beam pointing of the transmitted sensing signal may or may not require meeting the target conditions. For example, after obtaining the measurement results corresponding to at least one echo signal, the first device can adjust the beam pointing of the transmitted sensing signal based on these results. Even if the measurement results of the echo signals meet the reference values, i.e., meet the expected echo signal reception quality, the transmission power of the sensing signal can be minimized to save power consumption.

[0145] The target conditions are illustrated below with examples. The target conditions may include at least one of the following first, second, third, fourth, or fifth conditions. Examples of each condition are provided below. In each of these conditions, the first measurement result can be understood as the minimum measurement result among the measurement results corresponding to at least one echo signal. For example, the at least one echo signal can be the echo signal corresponding to at least one sensing target within the coverage area of ​​a sensing beam. For example, the at least one echo signal can be the echo signal corresponding to all sensing targets sensed by the first device, and these all sensing targets can be sensing targets within the coverage area of ​​one or more sensing beams. By determining whether the minimum measurement result satisfies the target conditions, it can be ensured that even the sensing targets that are most difficult to satisfy the sensing accuracy requirements can meet the sensing accuracy requirements, thus ensuring that all sensing targets can meet the sensing accuracy requirements.

[0146] The reference value can be understood as the expected measurement result of at least one echo signal, that is, the expected reception quality of the echo signal, and this reference value may be indicated by a second device.

[0147] The first condition includes: the difference between the first measurement result and the reference value is greater than or equal to a first threshold. For example, the first threshold can be greater than or equal to 0, that is, the first measurement result is greater than or equal to the reference value.

[0148] The second condition includes: the first measurement result is greater than or equal to the second threshold. For example, the second threshold may be greater than or equal to a reference value.

[0149] The third condition includes: the difference between the reference value and the first measurement result is greater than or equal to a third threshold. For example, the third threshold can be greater than or equal to 0, meaning the reference value is greater than or equal to the first measurement result. The third threshold can be determined based on the first device's current transmission power and its maximum transmission power. For instance, the third threshold is equal to the first device's maximum transmission power minus its current transmission power. The third threshold can be determined by the first device. Setting the third threshold to the first device's maximum transmission power minus its current transmission power ensures that the first device only reports the measurement report when it adjusts to its maximum transmission power, avoiding frequent reporting, consuming network resources, and fully utilizing the first device's adaptive power adjustment to meet sensing accuracy requirements.

[0150] The fourth condition includes: the first measurement result is less than or equal to the fourth threshold. The fourth threshold is less than or equal to the reference value.

[0151] The fifth condition includes: the change between the first measurement result and the second measurement result is greater than or equal to the fifth threshold, where the second measurement result is the minimum measurement result of the previous cycle, and the first measurement result can be understood as the minimum measurement result of the current cycle; or, the second measurement result is the value last reported by the first device. The value last reported by the first device can be the minimum measurement result of a historical cycle. The minimum measurement result can be the minimum measurement result among at least one echo signal received within a corresponding cycle.

[0152] The thresholds and / or target conditions included in the first to fifth conditions above can also be indicated by the second device to the first device. For example, some conditions can be predefined, and the second device can select the conditions included in the target conditions from the predefined conditions and indicate them to the first device. For example, the second device can indicate the identifier of the conditions included in the target conditions and / or the thresholds in each of the conditions included in the target conditions to the first device.

[0153] In some implementations, the operations triggered by the target conditions for the first device to perform may differ, and the thresholds within the same condition may vary. For example, the second threshold in the second condition that triggers the first device to send a measurement report to the second device may be greater than a reference value, while the second threshold in the second condition that triggers the first device to adjust the transmission power of the sensing signal may be equal to the reference value. As another example, the fourth threshold in the fourth condition that triggers the first device to send a measurement report to the second device may be less than the reference value, while the fourth threshold in the fourth condition that triggers the first device to adjust the transmission power of the sensing signal may be equal to the reference value.

[0154] The following examples illustrate each operation. It is understood that each of these operations can be performed individually or in combination:

[0155] Operation 1: Adjust the beam direction for transmitting the sensing signal.

[0156] The first device can transmit sensing signals through one or more sensing beams. For each sensing beam, the first device can adjust the beam pointing of the sensing beam to the optimal beam pointing, that is, adjust the beam pointing of the transmitting sensing signal to the optimal beam pointing. The following example uses adjusting the beam pointing of the first sensing beam to the optimal beam pointing; the first sensing beam is any sensing beam that transmits the sensing signal. At least one echo signal is the echo signal corresponding to different sensing targets within the coverage area of ​​the first sensing beam.

[0157] The first device can acquire the measurement results of each echo signal in the at least one echo signal, as well as the angle of arrival of each echo signal. For example, as shown in Figure 4, the coverage area of ​​the first sensing beam includes two sensing targets, θ b The beam direction of the first sensing beam is θ1, the angle of arrival of the echo signal corresponding to sensing target 1 is θ2, and the angle of arrival of the echo signal corresponding to sensing target 2 is θ2.

[0158] The first device determines the optimal beam pointing of the first sensing beam based on the measurement results and angle of arrival of each echo signal. The following example illustrates the specific implementation of determining the optimal beam pointing, using RSRP as the measurement result:

[0159] Case 1: If the coverage area of ​​the first sensing beam includes a sensing target, the optimal beam direction is the direction of the echo signal corresponding to that sensing target.

[0160] Scenario 2: If the coverage area of ​​the first sensing beam includes multiple sensing targets, for example, as shown in Figure 4, where one sensing beam covers two sensing targets, determining the optimal beam pointing in the case of multiple sensing targets within the first sensing beam coverage area requires satisfying the following principle: Maximize the minimum RSRP (i.e., the first measurement result) among the RSRPs corresponding to the multiple echo signals, while the RSRPs of the echo signals of all sensing targets need to meet the reference value, i.e., meet the expected reception quality of the echo signals. Specifically: Maximize RSRP1, RSRP1 = min(RSRP1 / 2) i )

[0161] It also needs to meet RSRP requirements. i ≥RSRP0, i=1,2,3,…m, where RSRP0 is the reference value and m is the number of sensed targets. The following example illustrates the specific steps for the first device to determine the optimal beam direction when the above principles are met:

[0162] Step 1: Calculate the difference ΔRSRP between the RSRP of each echo signal and the reference value RSRP0. i ΔRSRP i =RSRP i -RSRP0

[0163] Where i = 1, 2, 3...m, and m is the number of perceived targets.

[0164] Step 2: Calculate the angle of arrival θ for each echo signal. i Antenna gain loss Δf relative to the beam pointing of the first sensing beam i Where, Δf i =f(θ) i )-f(θ b i = 1, 2, 3, ..., m. m is the number of perceived targets. f(θ) b f(θ) represents the antenna gain corresponding to the beam direction of the first sensing beam in the antenna pattern of the first device. i Let be the antenna gain corresponding to the angle of arrival of the echo signal of the i-th sensed target in the antenna pattern of the first device.

[0165] Step 3: Traverse the sensing targets within the coverage area of ​​the first sensing beam and determine the beam angle range for each sensing target that satisfies the reference value RSRP0: [θ i -θ i,d ,θ i +θ i,d ]. θ i,d =f -1 (ΔRSRP i +Δf i )

[0166] θ i,d This represents the corresponding antenna gain loss Δf i In the case of deviation from the arrival angle θ i The angle value of the direction.

[0167] Step 4: Determine whether the intersection of the beam angle ranges of all sensed targets that satisfy the reference value RSRP0 is empty.

[0168] Step 5: If the intersection is empty, send an indication message to the second device indicating that the sensing accuracy requirement cannot be met. If the intersection is not empty, record the minimum RSRP among the RSRPs of the echo signals corresponding to all sensing targets. The angle of arrival of the echo signal of the sensing target corresponding to the minimum RSRP is θ1. Within the intersection angle range, select the angle with the smallest difference from θ1 as the optimal beam pointing, that is, select the angle closest to the direction of θ1.

[0169] The optimal beam pointing of each sensing beam can be determined by referring to the determination methods in steps 1 to 5 above.

[0170] The first device can adjust the beam pointing of the first sensing beam to the optimal beam pointing and use the adjusted first sensing beam to transmit sensing signals. If the first device transmits sensing signals through multiple sensing beams, the beam pointing of each sensing beam is adjusted to the optimal beam pointing corresponding to that sensing beam, and the sensing signal is transmitted using the adjusted sensing beam. After transmitting the sensing signal using the sensing signal with the optimal beam pointing, at least one received echo signal can be further measured to obtain the measurement results corresponding to each echo signal. Based on the measurement results corresponding to at least one echo signal, the transmission power of the sensing signal is adjusted and / or a measurement report is sent to the second device. Specific details can be found in the descriptions of subsequent operations 2 and 3, and will not be elaborated here. Further adjusting the transmission power of the sensing signal under the optimal beam pointing condition can minimize the transmission power of the sensing signal and save power consumption.

[0171] Operation 2: Adjust the transmission power of the sensing signal.

[0172] The first device can adjust the transmission power of the sensing signal when the measurement results corresponding to at least one echo signal meet the target conditions. For example, if the first measurement result meets the first and / or second conditions in the target conditions, the transmission power of the sensing signal can be reduced to save power consumption. If the first measurement result meets the third and / or fourth conditions in the target conditions, the transmission power of the sensing signal can be increased to meet the expected reception quality of the echo signal, i.e., meet the reference value, and thus meet the sensing accuracy requirements. The first measurement result is the minimum measurement result among the measurement results corresponding to at least one echo signal.

[0173] In this embodiment of the application, when the first device adjusts the transmission power of the sensing signal, it can determine the specific way to adjust the transmission power of the sensing signal based on the target conditions satisfied by the measurement results corresponding to at least one echo signal, the sensing strategy preferred by the first device, and the sensing strategy preferred by the second device. The following is an explanation with reference to specific examples.

[0174] Example 1: If the measurement results corresponding to at least one echo signal satisfy a first condition and / or a second condition, that is, if the first measurement result satisfies the first condition and / or the second condition (the target condition includes the first condition and / or the second condition), the transmission power of the sensing signal can be reduced only if both the sensing strategy preferred by the first device and the sensing strategy preferred by the second device are power-priority strategies. Here, the power-priority strategy indicates prioritizing saving the transmission power of the sensing signal; that is, the first device can only reduce the transmission power of the sensing signal to save transmission power, and the first device cannot increase the transmission power of the sensing signal. When it is necessary to increase the transmission power of the sensing signal, for example, when the minimum measurement result among the measurement results corresponding to at least one echo signal is less than the reference value, since both the first and second devices prefer a power-first strategy, the transmission power of the sensing signal cannot be increased. However, the second device can be requested to allocate more time-frequency resources of the sensing signal to meet the sensing accuracy requirements. That is, the first device will send a measurement report, triggering the second device to adjust the time-frequency resources of the sensing signal to allocate more time-frequency resources to meet the sensing accuracy requirements, thereby achieving the purpose of prioritizing the saving of the transmission power of the sensing signal. The target conditions for triggering the first device to send a measurement report can be referred to the specific description of operation 3. For example, it can be that the minimum measurement result among the measurement results corresponding to at least one echo signal is less than or equal to the fourth threshold, and / or the difference between the reference value and the first measurement result is greater than or equal to the third threshold, and the first device sends a measurement report.

[0175] The first device may reduce the transmission power of the sensing signal according to a first power step size, which may be indicated by a second device. The first power step size is the amount of power that needs to be reduced in each step of the sensing signal transmission power reduction. The first power step size and the second power step size may be the same or different.

[0176] Example 2: If the measurement results corresponding to at least one echo signal satisfy the third condition and / or the fourth condition, that is, if the first measurement result satisfies the third condition and / or the fourth condition (the target condition includes the third condition and / or the fourth condition), and if both the first device's preferred sensing strategy and the second device's preferred sensing strategy are resource-priority strategies, then the transmission power of the sensing signal can be increased. Here, the resource-priority strategy indicates prioritizing the conservation of time-frequency resources in the sensing signal; that is, the first device can only increase the transmission power of the sensing signal to avoid increasing the time-frequency resources of the sensing signal, thereby achieving the sensing accuracy requirement and prioritizing the conservation of time-frequency resources. The first device cannot reduce the transmission power of the sensing signal. In cases where it is necessary to reduce the transmission power of the sensing signal, for example, when the minimum measurement result among the measurement results corresponding to at least one echo signal is greater than the reference value, since both the first and second devices prefer a resource priority strategy, they cannot reduce the transmission power of the sensing signal. However, they can request the second device to allocate fewer time-frequency resources of the sensing signal to meet the reference value. The first device can send a measurement report to trigger the second device to adjust the time-frequency resources of the sensing signal to allocate fewer time-frequency resources, thereby achieving the purpose of prioritizing the saving of time-frequency resources of the sensing signal. The target conditions for triggering the first device to send a measurement report can be referred to the specific description of operation 3. For example, it can be that the minimum measurement result among the measurement results corresponding to at least one echo signal is greater than a second threshold, and / or the difference between the first measurement result and the reference value is greater than or equal to a first threshold, and the first device sends a measurement report.

[0177] The first device may increase the transmission power of the sensing signal according to a second power step size, which is indicated by the second device. The second power step size is the amount of power that needs to be increased in the transmission power of the sensing signal each time.

[0178] Understandably, if the measurement result of the echo signal received by the first device still does not meet the reference value when the first device increases the transmission power of the sensing signal to the maximum transmission power, then the first device can be triggered to send a measurement report to the second device when the measurement result of at least one echo signal meets the third condition and / or the fourth condition.

[0179] In Examples 1 and 2 above, if the measurement results corresponding to at least one echo signal satisfy at least one of the first, second, third, fourth, and fifth conditions, and if the preferred sensing strategy of the first device differs from that of the second device, or if both the preferred sensing strategies of the first and second devices are compromise strategies, then a measurement report needs to be sent. The second device determines, based on the measurement report, to adjust the transmission power of the sensing signal and / or adjust the time-frequency resources of the sensing signal, as detailed in the specific description of Operation 3. Accordingly, the thresholds in each condition can be thresholds used to trigger the first device to send a measurement report. The compromise strategy can be understood as simultaneously saving the transmission power of the sensing signal and saving the time-frequency resources of the sensing signal.

[0180] Operation 3: Send a measurement report to the second device. The measurement report indicates relevant information about the measurement results corresponding to at least one echo signal.

[0181] The first device may send a measurement report to the second device if the measurement results corresponding to at least one echo signal meet the target conditions.

[0182] In this embodiment, the target condition can be determined by the first device based on a perception strategy preferred by the first device and a perception strategy preferred by the second device. The perception strategy preferred by the first device is one of a resource-priority strategy, a power-priority strategy, or a compromise strategy, and the perception strategy preferred by the second device is also one of a resource-priority strategy, a power-priority strategy, or a compromise strategy. The perception strategy preferred by the second device can be indicated by the second device to the first device.

[0183] For example, if both the first and second devices prefer a power-first sensing strategy, then the target conditions include a third and / or a fourth condition. That is, when both the first and second devices prefer a power-first sensing strategy, if the measurement results corresponding to at least one echo signal (i.e., the first measurement result) satisfy the third and / or fourth conditions, the first device will send a measurement report to the second device. When the measurement results corresponding to at least one echo signal satisfy the third and / or fourth conditions, it is necessary to increase the transmission power of the sensing signal. However, since both the first and second devices prefer a power-first strategy, i.e., prioritizing saving the transmission power of the sensing signal, the transmission power of the sensing signal cannot be increased; instead, a measurement report can only be sent to the second device. The second device then allocates more time-frequency resources to ensure that the first measurement result meets the reference value.

[0184] For example, if both the first and second devices prefer a resource-first sensing strategy, the target conditions include a first condition and / or a second condition. That is, when both the first and second devices prefer a resource-first sensing strategy, if the measurement results corresponding to at least one echo signal (i.e., the first measurement result) satisfy the first condition and / or the second condition, the first device will send a measurement report to the second device. When the measurement results corresponding to at least one echo signal satisfy the first condition and / or the second condition, it is necessary to reduce the transmission power of the sensing signal. However, since both the first and second devices prefer a resource-first strategy, i.e., prioritizing the saving of time-frequency resources for the sensing signal, the transmission power of the sensing signal cannot be reduced; instead, a measurement report can only be sent to the second device. Thus, the second device schedules fewer time-frequency resources, prioritizing the saving of time-frequency resources rather than prioritizing the saving of transmission power.

[0185] For example, if both the perception strategy preferred by the first device and the perception strategy preferred by the second device are compromise strategies, or if the perception strategies preferred by the first device and the second device differ, the target condition may include at least one of a first condition, a second condition, a third condition, a fourth condition, or a fifth condition. That is, if the measurement results corresponding to at least one echo signal satisfy at least one of the first, second, third, fourth, or fifth conditions, then the first device will send a measurement report to the second device. This allows the second device to determine how to adjust the transmission power of the sensing signal and / or adjust the time-frequency resources of the sensing signal.

[0186] In this embodiment of the application, the measurement report may indicate at least one of the following values: the difference between a first measurement result and a reference value; the difference between a first measurement result and a second threshold; the difference between a first measurement result and a fourth threshold; the change between the first measurement result and the second measurement result; the average value of the measurement results corresponding to at least one echo signal; the first measurement result; the difference between the average value of the measurement results corresponding to at least one echo signal and the first measurement result; and the measurement result corresponding to at least one echo signal.

[0187] To save costs, the values ​​indicated in the aforementioned measurement report can be normalized based on the reporting unit δ to obtain the reported value included in the measurement report. The reported value is less than the value indicated in the measurement report. For example, the reported value = the value indicated in the measurement report / δ. The reporting unit δ can be indicated by a second device.

[0188] The feedback granularity of the values ​​indicated in the measurement report can be one of the following: sensing target, sensing beam, or sensing node. The feedback granularity of the values ​​indicated in the measurement report can also be indicated by a second device.

[0189] If the feedback granularity is a sensing beam, the measurement report can indicate at least one value corresponding to each sensing beam. For example, the measurement report can indicate a difference 1 corresponding to sensing beam 1 and a difference 2 corresponding to sensing beam 2. This difference can be, for example, the difference between a first measurement result and a reference value. Accordingly, in this embodiment, the first measurement result used to determine difference 1 is the minimum measurement result among the measurement results of the echo signals corresponding to different sensing targets within the coverage area of ​​sensing beam 1. The first measurement result used to determine difference 2 is the minimum measurement result among the measurement results of the echo signals corresponding to different sensing targets within the coverage area of ​​sensing beam 2.

[0190] If the feedback granularity is a sensing node, the measurement report can indicate at least one value corresponding to a sensing node, which is the first device. Accordingly, in the embodiments of this application, at least one echo signal used to determine the first measurement result can be the echo signals corresponding to all sensing targets sensed by the first device, and all sensing targets sensed by the first device can be sensing targets within the coverage area of ​​the same sensing beam or different sensing beams.

[0191] If the feedback granularity is a sensing target, the measurement report can indicate at least one value corresponding to each sensing target. For example, the measurement report can indicate at least one of the following: the measurement result corresponding to each sensing target, the difference between the measurement result corresponding to each sensing target and the reference value, the difference between the measurement result corresponding to each sensing target and the second threshold or the fourth threshold, and the change value between the measurement result corresponding to each sensing target and the second measurement result.

[0192] The second device receives a measurement report from the first device and adjusts the transmission power of the sensing signal and / or adjusts the time-frequency resources of the sensing signal based on the measurement report.

[0193] If the sensing signal is transmitted by a second device, for example, in the scenario shown in Figure 2A, the second device may transmit the sensing signal with an adjusted transmission power and / or transmit the sensing signal using adjusted time-frequency resources. For example, the second device may send adjustment information to the first device, which includes first indication information and / or second indication information, whereby the first indication information indicates the adjusted transmission power of the sensing signal and the second indication information indicates the adjusted time-frequency resources of the sensing signal.

[0194] If the sensing signal is sent by the first device, for example, in the scenario shown in Figure 2B, the second device can send adjustment information to the first device. This adjustment information includes first indication information and / or second indication information. The first indication information indicates the adjusted transmission power of the sensing signal, and the second indication information indicates the adjusted time-frequency resources for the sensing signal. If the adjustment information includes the first indication information, the first device can transmit the sensing signal using the adjusted transmission power. If the adjustment information includes the second indication information, the first device can transmit the sensing signal using the adjusted time-frequency resources.

[0195] The following examples illustrate how the second device adjusts the transmission power of the sensing signal and / or adjusts the time-frequency resources of the sensing signal.

[0196] Example 1: If the sensing strategy preferred by the first device and the sensing strategy preferred by the second device are both power-first strategies, and the measurement results corresponding to at least one echo signal satisfy the third condition and / or the fourth condition respectively, that is, the target conditions include the third condition and / or the fourth condition, the second device can increase the time-frequency resources of the sensing signal.

[0197] Example 2: If the perception strategy preferred by the first device and the perception strategy preferred by the second device are both resource-priority strategies, and the measurement results corresponding to at least one echo signal satisfy the first condition and / or the second condition respectively, that is, the target condition includes the first condition and / or the second condition, the second device reduces the time-frequency resources of the sensing signal.

[0198] Example 3: If both the preferred sensing strategy of the first device and the preferred sensing strategy of the second device are compromise strategies, or if the preferred sensing strategies of the first device and the preferred sensing strategies of the second device are different, and the measurement results corresponding to at least one echo signal satisfy at least one of the first, second, third, fourth, or fifth conditions (i.e., the target conditions may include at least one of the first, second, third, fourth, or fifth conditions), in one implementation, the second device can simultaneously adjust the time-frequency resources and transmission power of the sensing signal. For example, if the measurement results corresponding to at least one echo signal satisfy the first and / or second conditions, the transmission power of the sensing signal can be reduced, and the time-frequency resources of the sensing signal can be decreased; or, for example, if the measurement results corresponding to at least one echo signal satisfy the third and / or fourth conditions, the transmission power of the sensing signal can be increased, and the time-frequency resources of the sensing signal can be increased. In another implementation, the second device can determine whether to adjust the transmission power or the time-frequency resources of the sensing signal based on the currently available schedulable idle time-frequency resources and / or the interference of the first device's transmission power of the sensing signal to other devices. For example, if the measurement results corresponding to at least one echo signal satisfy the third and / or fourth conditions, and if the currently available idle time-frequency resources are limited and resources are scarce, then the transmission power of the sensing signal can be increased; if increasing the transmission power of the sensing signal would cause significant interference to other devices, then more time-frequency resources can be allocated. As another example, if the measurement results corresponding to at least one echo signal satisfy the first and / or second conditions, and if the currently available idle time-frequency resources are limited and resources are scarce, then the allocated time-frequency resources can be reduced; if transmitting the sensing signal has already caused significant interference to other devices, then the transmission power of the sensing signal can be reduced.

[0199] Please refer to Figure 5, which shows an example of a communication method provided in an embodiment of this application. The communication method shown in Figure 5 can be an example of a communication method based on the application scenario shown in Figure 2A. This communication method includes the following steps, which may include only some of the steps. The steps are described below:

[0200] 501, The second device sends sensing and measurement instruction information.

[0201] The sensing measurement indication information can indicate at least one of the following: reference value, target condition, threshold value among the various conditions included in the target condition, feedback granularity of the value indicated in the measurement report, reporting unit of the value indicated in the measurement report, and sensing strategy preferred by the second device.

[0202] 502, the second device sends the first scheduling message.

[0203] The first scheduling information can be used to indicate the time-frequency resources for sensing signals, so that the first device can receive the echo signal on the indicated time-frequency resources.

[0204] 503, The second device transmits a sensing signal at the first transmission power.

[0205] The second device can transmit sensing signals using one or more sensing beams. Each sensing beam covers one or more sensing targets.

[0206] 504, The first device receives the echo signal.
