[0002] The communication and sensing integrated system realizes cooperative sensing node scheduling and interference coordination through the configuration of communication and sensing reference signals. When the communication and sensing integrated system needs to schedule a certain node, it will configure the resources of the communication and sensing reference signal for this node, otherwise it will not configure. In related technologies, the sensing signal commonly used for sensing target positioning is the positioning reference signal (PRS), but the PRS only supports direct configuration through the LTE positioning protocol (LPP) signaling or the NR positioning protocol A (NRPPa) signaling.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0034] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0035] To facilitate the understanding of the embodiments of the present application, the following content is first described.

[0036] The embodiments of the present application are applicable to cooperative sensing. The types of cooperative sensing include the following two categories:

[0037] (1) The first category is single transmit and single receive. As Figure 1A shown, the process of single transmit and single receive includes: node A sends a sensing signal; the echo signal formed after being reflected by the sensing target is received by node B; node B measures the echo signal, and the measurement result of the echo signal is calculated by the sensing processor and then the sensing result of the sensing target is output.

[0038] (2) The second category is single transmit and multiple receive / multiple transmit and single receive. As Figure 1B shown, the process of single transmit and multiple receive / multiple transmit and single receive includes: node A, node B, and node C are respectively the transmitting node (or receiving node) and receiving node (or transmitting node) to realize the transmission of the sensing signal and the reception and measurement of the echo signal. Compared with single transmit and single receive cooperative communication and sensing, in this type, the network can select appropriate transmitting nodes and receiving nodes to participate in cooperative sensing through node scheduling, interference coordination, etc., to improve the sensing performance.

[0039] The following will, with reference to the accompanying drawings, elaborate on the resource allocation method, device, communication equipment, and readable storage medium provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0040] Please refer to Figure 2 , Figure 2 which is a flowchart of a resource allocation method provided by an embodiment of the present application. This method is applied to a terminal, such asFigure 2 As shown, the method includes the following steps:

[0041] Step 21: The terminal receives first configuration information from the base station, where the first configuration information is used to configure a first resource for a first sensing signal, and the first sensing signal is used for target sensing;

[0042] Step 22: When the first condition is met, the terminal sends configuration update information to the base station; the first condition includes any one of the following: the first resource cannot meet the resource requirements of the terminal, or the first resource is in excess;

[0043] Step 23: The terminal receives second configuration information from the base station, where the second configuration information is used to configure a second resource for the first sensing signal.

[0044] In an embodiment of the present application, the first sensing signal includes, but is not limited to, a positioning reference signal (PRS), a channel state information reference signal (CSI-RS), a phase-tracking reference signal (PTRS), etc.

[0045] The second resource is different from the first resource. The second resource can be understood as being obtained based on the configuration update information of the terminal on the basis of the first resource. That is to say, the first configuration information configures the pre-updated / non-updated resource, and the second configuration information configures the updated resource.

[0046] Optionally, the first configuration information can be carried by radio resource control (RRC) signaling, and the second configuration information can be carried by downlink control information (DCI).

[0047] Optionally, the manner in which the terminal sends the configuration update information includes, but is not limited to, being carried by uplink control information (UCI).

[0048] Optionally, after the above step 23, the terminal can perform target sensing according to the second resource, such as using the first sensing signal to perform target sensing on the second resource. This sensing method can be single transmit and single receive, that is, the base station transmits and this terminal receives; or it can be single transmit and multiple receive, that is, the base station transmits and multiple cooperative terminals receive.

[0049] Optionally, the perception types of the target perception include, but are not limited to, target detection, ranging, speed measurement, angle measurement, etc., so that the present solution can support multiple perception types and support the measurement of multiple functions, improving the perception performance.

[0050] Optionally, the first resource and the second resource are bound to the perception type. In this way, through the binding of the first resource and the second resource to the perception type, after the first resource and the second resource are configured, the corresponding perception type can be determined without having to indicate the perception type again, thus saving resource overhead.

[0051] In the resource configuration method of the embodiment of the present application, after the terminal receives the first configuration information from the base station, the first configuration information is used to configure the first resource of the first perception signal, and the first perception signal is used for target perception. When the first resource cannot meet the resource requirements of the terminal or the first resource is in excess, the terminal can send configuration update information to the base station and receive the second configuration information from the base station. The second configuration information is used to configure the second resource of the first perception signal. Thus, in combination with the characteristic that the perception resource requirements (affected by factors such as perception performance requirements and signal-to-interference-plus-noise ratio of the received perception signal) in the target perception stage often change, a multi-level configuration mechanism for the perception signal can be adopted to realize flexible configuration of the perception signal, and enable the base station to reconfigure resources for the terminal when the configured resources cannot meet the resource requirements of the terminal or are in excess, so as to meet the resource requirements of the terminal and avoid resource waste.

[0052] In addition, with the help of the multi-level configuration mechanism in the present application, the perception configuration overhead can also be saved, the perception configuration efficiency can be improved, and real-time scheduling of the perception resources can be realized.

[0053] For example, when the first configuration information is carried by RRC signaling and the second configuration information is carried by DCI, a multi-level configuration mechanism combining high-layer signaling and DCI can be realized.

[0054] Optionally, the configuration update information may include at least one of the following:

[0055] The first indication information, which is used to indicate an update of the resource configuration of the first perception signal;

[0056] The second indication information, which is used to indicate that the first resource does not meet the resource requirements of the terminal, or to indicate that the first resource is in excess;

[0057] The resource information of the first perception signal required by the terminal.

[0058] In this way, the base station can update the resource configuration of the first perception signal based on the received first indication information, second indication information, and / or the resource information of the first perception signal required by the terminal.

[0059] For example, the configuration update information may include the first indication information and the resource information of the first sensing signal of the terminal requirements, such that after receiving the first indication information, the base station updates the resource configuration of the first sensing signal according to the resource information of the first sensing signal of the terminal requirements.

[0060] For another example, the configuration update information may include the second indication information and the resource information of the first sensing signal of the terminal requirements, such that after receiving the second indication information, the base station updates the resource configuration of the first sensing signal according to the resource information of the first sensing signal of the terminal requirements.

[0061] For yet another example, the configuration update information may only include the resource information of the first sensing signal of the terminal requirements, such that the base station updates the resource configuration of the first sensing signal according to the resource information of the first sensing signal of the terminal requirements.

[0062] For yet another example, the configuration update information may only include the first indication information or the second indication information, such that the base station updates the resource configuration of the first sensing signal according to the first indication information or the second indication information in combination with its own situation.

[0063] In the embodiments of the present application, the terminal may determine that the currently configured resources need to be updated and send configuration update information to the base station when the currently configured resources cannot meet the terminal resource requirements or are in excess (i.e., far exceed the terminal resource requirements).

[0064] Optionally, if the configured resources meet the terminal resource requirements and are not in excess, the terminal may directly perform target sensing according to the configured resources without sending a resource configuration update indication to the base station.

[0065] It should be noted that for the resource requirements of the terminal, they can be obtained by converting the sensing performance; the sensing performance includes sensing accuracy, which can be obtained by measuring the first sensing signal, and the specific measurement content includes but is not limited to sensing resolution, Signal to Interference plus Noise Ratio (SINR), etc. After obtaining the sensing performance, the resource requirements corresponding to the sensing performance can be obtained by querying a pre-set table.

[0066] Optionally, the resource configuration method in this embodiment may further include:

[0067] 1) When the ratio of the first parameter to the configuration parameter of the first resource is greater than or equal to the first update threshold, the terminal determines that the first resource cannot meet the resource requirements of the terminal;

[0068] 2) Alternatively, when the ratio of the configuration parameter of the first resource to the first parameter is greater than or equal to the second update threshold, the terminal determines that the first resource is in excess, that is, determines that the first resource far exceeds the resource requirements of the terminal.

[0069] Optionally, the configuration parameter of the first resource includes at least one of the following:

[0070] Resource Element (RE) interval, symbol interval, repetition factor.

[0071] The first parameter in the above 1) and 2) is the parameter of the resource of the first perception signal of the terminal demand corresponding to the configuration parameter of the first resource, such as RE interval, symbol interval or repetition factor, etc. The first update threshold and the second update threshold can be pre-configured for the terminal through higher layer signaling (such as RRC signaling), or can be pre-set, protocol-agreed, etc., and this is not limited.

[0072] In this way, with the help of the first update threshold and the second update threshold, it can be simply determined whether the configured resources meet the terminal resource requirements or are in excess.

[0073] For example, referring to Figure 3 As shown, the target perception process in this embodiment may include:

[0074] S1: The base station initially configures the first resource of the UE-specific first perception signal for the terminal through RRC signaling for target perception; the configuration parameter a of the first resource includes but is not limited to RE interval, symbol interval, repetition factor, etc.

[0075] S2: The terminal determines the resource demand parameter a' of the first perception signal, and the resource demand parameter a' can be characterized by RE interval, symbol interval or repetition factor.

[0076] S3: The terminal divides the resource demand parameter a' of the first perception signal by the corresponding parameter a configured in the first resource, and compares the obtained ratio with the first update threshold and the second update threshold to determine whether the current resource configuration needs to be updated:

[0077] ① If the reciprocal of the ratio is greater than or equal to the first update threshold, it indicates that the current configuration cannot meet the terminal resource requirements (it can be understood as unable to meet the perception performance requirements), and the resource configuration of the first perception signal needs to be updated, and step S4 is executed;

[0078] ② If the ratio is greater than or equal to the second update threshold, it indicates that the current configuration far exceeds the perception performance requirements, that is, the first resource is in excess, and the resource configuration of the first perception signal needs to be updated, and S4 is executed;

[0079] ③ Otherwise, if the conditions in ① and ② above are not met, it indicates that the resource allocation of the first sensing signal does not need to be updated, and step S7 is executed.

[0080] Optionally, the first update threshold and the second update threshold are pre-configured for the terminal through higher-layer signaling.

[0081] S4: The terminal sends a resource allocation update indication (corresponding to the first indication information above) and a resource requirement parameter a' to the base station. Optionally, the resource allocation update indication and the resource requirement parameter a' can be carried in the UCI and sent to the base station.

[0082] S5: After the base station receives the resource allocation update indication and determines that the resource allocation needs to be updated, it updates the resource allocation of the first sensing signal according to the resource requirement parameter a', and notifies the terminal of the configuration result through DCI.

[0083] S6: The terminal performs target sensing using the first sensing signal with the updated configuration.

[0084] S7: The terminal performs target sensing using the current first sensing signal; at this time, the base station determines to continue using the already configured first resource to send the first sensing signal.

[0085] The following uses the RE interval as an example to illustrate the configuration update process.

[0086] Target sensing scenario 1:

[0087] Suppose the base station cooperates with multiple terminals to achieve target ranging. First, the base station configures the following parameters for the SensingRS resources of the cooperative terminals' sensing signals through RRC signaling, which characterize the SensingRS frequency-domain pattern:

[0088] SensingRS-REDistance = 4

[0089] SensingRS-REOffset = 0

[0090] The above configuration indicates that the SensingRS signal appears once every 4 REs, and the first SensingRS signal appears on the RE numbered 0.

[0091] In addition, the base station also sends the first update threshold (SensingRS-Threshold1) and the second update threshold (SensingRS-Threshold2) to the cooperative terminals through RRC signaling, as follows:

[0092] SensingRS-Threshold1 = 1

[0093] SensingRS-Threshold2 = 2

[0094] Secondly, the terminal determines the RE interval requirement by measuring SensingRS as follows:

[0095] SensingRS-REDistance-Demand = 6

[0096] Divide this RE interval requirement by the configured RE interval of SensingRS, and compare the obtained ratio with the first update threshold and the second update threshold: Since 4 / 6 < 1 and 6 / 4 < 2, it indicates that the configured RE interval can meet the RE interval requirement and the RE interval requirement is only slightly larger than the configured RE interval. Therefore, there is no need to update the existing configuration.

[0097] Finally, the terminal performs target sensing using the existing SensingRS configuration.

[0098] Target sensing scenario 2:

[0099] Suppose the base station collaborates with multiple terminals to achieve target ranging. First, the base station configures the following parameters for the SensingRS resources of the collaborative terminals through RRC signaling, which characterize the SensingRS frequency domain pattern:

[0100] SensingRS-REDistance = 4

[0101] SensingRS-REOffset = 0

[0102] The above configuration indicates that the SensingRS signal appears once every 4 REs, and the first SensingRS signal appears on the RE numbered 0.

[0103] In addition, the base station also sends the first update threshold (SensingRS-Threshold1) and the second update threshold (SensingRS-Threshold2) to the collaborative terminals through RRC signaling as follows:

[0104] SensingRS-Threshold1 = 1

[0105] SensingRS-Threshold2 = 2

[0106] Secondly, the terminal determines the RE interval requirement by measuring SensingRS as follows:

[0107] SensingRS-REDistance-Demand = 2

[0108] Divide the RE interval requirement by the RE interval configured by SensingRS, and compare the obtained ratio with the first update threshold and the second update threshold: Since 4 / 2 > 1, it indicates that the configured RE interval cannot meet the RE interval requirement, so the existing configuration needs to be updated.

[0109] Then, the terminal reports the following information through UCI to assist the base station in updating the SensingRS resource configuration:

[0110] SensingRS-update-indicator = 100

[0111] SensingRS-REDistance-Demand = 2

[0112] The 1st - 3rd bits in the above SensingRS-update-indicator respectively indicate whether the RE interval, symbol interval, and repetition factor need to be modified; taking 0 indicates no modification is required, and taking 1 indicates that modification is required.

[0113] After receiving the above parameters, the base station can determine from the 1st parameter in the SensingRS-update-indicator that the RE interval in the SensingRS resource configuration needs to be updated, and determine from the parameter SensingRS-REDistance-Demand that the number of updated RE intervals is 2. At this time, the base station can notify the cooperative terminal of the updated SensingRS parameters through the following DCI signaling:

[0114] SensingRS-REDistance = 2

[0115] SensingRS-REOffset = 0

[0116] The updated SensingRS frequency domain pattern is: The SensingRS signal appears once every 2 REs, and the first SensingRS signal appears on the RE numbered 0.

[0117] Finally, the terminal performs target sensing using the updated SensingRS configuration.

[0118] In the embodiments of the present application, in order to effectively implement target sensing, it is possible to first sense whether there is a sensing target within the coverage range in the initial stage, and then, after sensing that there is a sensing target within the coverage range, start the fine sensing of the sensing target.

[0119] Optionally, before the above step 21, the resource configuration method in this embodiment may further include:

[0120] The terminal receives third configuration information from the base station, where the third configuration information is used to configure a third resource for a second sensing signal, and the second sensing signal is used for target detection;

[0121] The terminal measures the second sensing signal on the third resource and reports the measurement result.

[0122] Thus, since the sensing target in the sensing system is usually a non-in-network object, a sensing target detection stage can be introduced before target sensing, so as to configure resources for the target detection stage and the target sensing stage respectively, effectively realizing target sensing.

[0123] Optionally, the second sensing signal includes but is not limited to a positioning reference signal (PRS), a channel state information reference signal (CSI-RS), a phase tracking reference signal (PTRS), etc. The type of the second sensing signal may be the same as or different from that of the above-mentioned first sensing signal. For example: both the second sensing signal and the first sensing signal are the positioning reference signal PRS; or, the first sensing signal is the positioning reference signal PRS, and the second sensing signal is the phase tracking reference signal PTRS.

[0124] Optionally, the first configuration information is sent when it is determined according to the measurement result that there is a sensing target, so as to start the fine sensing of the sensing target after it is sensed that there is a sensing target within the coverage area.

[0125] Optionally, the third resource is bound to the sensing type. In this way, through the binding of the third resource and the sensing type, after the third resource is configured, the corresponding sensing type can be determined as target detection without having to indicate the sensing type again, thus saving resource overhead.

[0126] Optionally, combining the characteristics that the sensing types in the two stages of target detection and target sensing in the sensing process are different, when configuring the sensing signal resources, the sensing resources can be bound to the sensing type, so as to implicitly indicate the corresponding sensing type by means of the configured sensing resources.

[0127] Optionally, the method for determining whether there is a sensing target may include at least one of the following:

[0128] Base station determination method; this method is a direct determination method of the base station. In this method, the terminal reports the measured quantity after each measurement;

[0129] Terminal-assisted determination method; this method is an indirect determination method of the base station. In this method, the terminal only needs to report the measured quantity and the determination result after the last measurement;

[0130] Terminal determination method; in this method, the terminal directly reports the determination result to the base station after the measurement is completed.

[0131] For example, refer to Figure 4 As shown, the target detection process in this embodiment may include:

[0132] S1: The base station configures a third resource for a second sensing signal of a specific cell (cell-specific) for the terminal through RRC signaling and sends the second sensing signal for target detection sensing.

[0133] Optionally, before configuring the third resource, a resource set of the second sensing signal may be configured first, and the sensing types bound to the sensing resources in the same resource set are the same.

[0134] Optionally, to inform the terminal of the sensing type, the base station may bind the configured sensing resources to a certain sensing type. The binding methods include but are not limited to: the base station implicitly indicates in the measurement report configuration corresponding to the sensing resources, and adds a sensing type field indication when configuring the sensing resources.

[0135] S2: The terminal measures the second sensing signal, and the base station or the terminal determines whether there is a sensing target in the sensing area. As Figure 4 shown, the corresponding determination methods include:

[0136] ① Terminal determination method, that is, the terminal determines whether the sensing target appears / exists: The terminal measures and determines whether the sensing target exists, and reports sensing_indicator; when the number of terminals reporting sensing_indicator = 1 exceeds the threshold, the base station determines that there is a sensing target, otherwise there is no sensing target;

[0137] ② Terminal-assisted determination method, that is, the terminal assists in determining whether the sensing target appears / exists: The terminal measures and reports {measurement_result, sensing_indicator, confidence_leve}; the base station determines whether the sensing target appears / exists according to the results reported by the terminal;

[0138] ③ Base station determination method, that is, the base station determines whether the sensing target appears / exists: The terminal measures and reports measurement_result; the base station determines whether the sensing target appears / exists according to the results reported by the terminal;

[0139] Optionally, the determination methods of ① to ③ can be reflected in the measurement report configured in S1.

[0140] S3: When there is a sensing target, the base station notifies each cooperative terminal and enters the target sensing stage.

[0141] The following describes the target detection in combination with specific embodiments.

[0142] In this embodiment, one base station and M terminals are set to participate in cooperative sensing to achieve target detection. The sensing transmitter is located at the base station, and the sensing receiver is located at the terminal.

[0143] First, the base station configures SensingRS resources for target detection through RRC signaling. To inform the terminal of the sensing type and the sensing target judgment method, the base station adds the SensingRS-ReportConfig field to the high-layer parameter SensingRS-Measurement IE and implicitly indicates it by configuring the terminal measurement reporting quantity.

[0144] For example, in the reporting quantity of a certain cooperative terminal, sensing_indicator = 0 indicates that the cooperative terminal judges that the sensing target does not exist; sensing_indicator = 1 indicates that the cooperative terminal judges that the sensing target exists; confidence_level indicates the confidence level judged by the cooperative terminal.

[0145] Regarding the sensing type indication:

[0146] When delay is fed back in the SensingRS-ReportConfig IE, it indicates that the resources configured by SensingRS-resourceSetID are used for ranging; and / or, when dopplershift is fed back in the SensingRS-ReportConfig IE, it indicates that the resources configured by SensingRS-resourceSetID are used for speed measurement; and / or, when AoA is fed back in the SensingRS-ReportConfig IE, it indicates that the resources configured by the parameter SensingRS-resourceSetID are used for angle measurement. In this embodiment, to achieve target detection, only dopplershift needs to be configured in the SensingRS-ReportConfig IE.

[0147] Regarding the sensing target judgment method indication:

[0148] When the sensing_indicator and confidence_level are not configured in the SensingRS-ReportConfig IE, it represents the base station judgment method; the base station uses the measurement quantities fed back by each cooperative terminal as input parameters and judges whether there is a sensing target through an internal algorithm;

[0149] When the SensingRS-ReportConfig IE configures both the sensing_indicator and the confidence_level simultaneously, it represents the terminal-assisted judgment method; the base station uses the measurement quantities, sensing_indicator, and confidence_level fed back by each cooperative terminal as input parameters, and judges whether there is a sensing target through an internal algorithm;

[0150] When the SensingRS-ReportConfig IE only configures the sensing_indicator, it represents the terminal judgment method; the terminal judges whether there is a sensing target through an internal algorithm. When more than a preset number of the M cooperative terminals feedback sensing_indicator = 1, it is determined that the sensing target exists; otherwise, it is determined that the sensing target does not exist.

[0151] When it is determined that the sensing target exists, the base station notifies each cooperative terminal and enters the target sensing phase.

[0152] Please refer to Figure 5 , Figure 5 which is a flowchart of a resource configuration method provided by an embodiment of the present application. This method is applied to a base station. As Figure 5 shown, the method includes the following steps:

[0153] Step 51: The base station sends first configuration information to the terminal, and the first configuration information is used to configure the first resource of the first sensing signal, and the first sensing signal is used for target sensing;

[0154] Step 52: The base station receives configuration update information from the terminal; the configuration update information is sent under the condition of meeting the first condition, and the first condition includes any one of the following: the first resource cannot meet the resource requirements of the terminal, the first resource is excessive;

[0155] Step 53: The base station sends second configuration information to the terminal, and the second configuration information is used to configure the second resource of the first sensing signal.

[0156] In the embodiment of the present application, the first sensing signal includes but is not limited to a positioning reference signal PRS, a channel state information reference signal CSI-RS, a phase tracking reference signal PTRS, etc. The second resource is different from the first resource. The second resource can be understood as being obtained based on the configuration update information of the terminal on the basis of the first resource.

[0157] Optionally, the first resource and the second resource are bound to the sensing type.

[0158] Optionally, the first configuration information may be carried by radio resource control (RRC) signaling, and the second configuration information may be carried by downlink control information (DCI).

[0159] Optionally, the manner in which the terminal sends the configuration update information includes, but is not limited to, being carried by uplink control information (UCI).

[0160] Optionally, the first resource and the second resource are bound to the sensing type. In this way, through the binding of the first resource and the second resource to the sensing type, the corresponding sensing type can be determined after the first resource and the second resource are configured, without having to indicate the sensing type, thereby saving resource overhead.

[0161] Therefore, in combination with the characteristic that the sensing resource requirements (affected by factors such as sensing performance requirements and signal-to-interference-plus-noise ratio of the received sensing signal) in the target sensing phase often change, a multi-level configuration mechanism for the sensing signal can be adopted, so as to achieve flexible configuration of the sensing signal, and enable the base station to reconfigure resources for the terminal when the configured resources cannot meet the resource requirements of the terminal or are excessive, thereby meeting the resource requirements of the terminal and avoiding resource waste.

[0162] For example, when the first configuration information is carried by RRC signaling and the second configuration information is carried by DCI, a multi-level configuration mechanism combining high-layer signaling and DCI can be implemented.

[0163] Optionally, the configuration update information may include at least one of the following:

[0164] The first indication information, which is used to indicate an update to the resource configuration of the first sensing signal;

[0165] The second indication information, which is used to indicate that the first resource does not meet the resource requirements of the terminal, or to indicate that the first resource is excessive;

[0166] The resource information of the first sensing signal required by the terminal.

[0167] In this way, the base station can update the resource configuration of the first sensing signal based on the received first indication information, second indication information, and / or the resource information of the first sensing signal required by the terminal.

[0168] Optionally, before step 51, the resource configuration method in this embodiment may further include:

[0169] The base station sends third configuration information to the terminal, and the third configuration information is used to configure a third resource for a second sensing signal, and the second sensing signal is used for target detection.

[0170] Therefore, since the sensing target in the sensing system is usually a non-in-network object, a sensing target detection stage can be introduced before target sensing, so as to allocate resources for the target detection stage and the target sensing stage respectively, and effectively achieve target sensing.

[0171] Optionally, the second sensing signal includes but is not limited to a positioning reference signal (PRS), a channel state information reference signal (CSI-RS), a phase tracking reference signal (PTRS), etc. The type of the second sensing signal may be the same as or different from that of the above first sensing signal. For example, both the second sensing signal and the first sensing signal are the positioning reference signal PRS; or, the first sensing signal is the positioning reference signal PRS, and the second sensing signal is the phase tracking reference signal PTRS.

[0172] Optionally, the third resource is bound to the sensing type. In this way, through the binding of the third resource and the sensing type, after the third resource is configured, the corresponding sensing type can be determined as target detection without further indicating the sensing type, thus saving resource overhead.

[0173] Optionally, considering the characteristic that the sensing types in the two stages of target detection and target sensing in the sensing process are different, when configuring the sensing signal resources, the sensing resources can be bound to the sensing type, so as to implicitly indicate the corresponding sensing type by means of the configured sensing resources.

[0174] Optionally, the above step 51 may include: when the base station determines that there is a sensing target, the base station sends the first configuration information to the terminal.

[0175] Optionally, the method for determining whether there is a sensing target may include at least one of the following:

[0176] Base station determination method; this is a direct determination method of the base station. In this method, the terminal reports the measurement quantity after each measurement.

[0177] Terminal-assisted determination method; this is an indirect determination method of the base station. In this method, the terminal only needs to report the measurement quantity and the determination result after the last measurement.

[0178] Terminal determination method; in this method, the terminal directly reports the determination result to the base station after the measurement is completed.
