[0077] To facilitate understanding of the embodiments of this application, the following points will be explained first:

[0078] In this application, "instruction" can include direct instruction, indirect instruction, explicit instruction, and implicit instruction. When describing a certain instruction information for the purpose of instructing A, it can be understood that the instruction information carries A, directly instructs A, or indirectly instructs A.

[0079] In this application, " / " can indicate that the objects before and after are in an "or" relationship. For example, A / B can mean A or B. "And / or" can be used to describe three relationships between the related objects. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. A and B can be singular or plural.

[0080] In this application, "at least one" means one or more, and "more than one" means two or more, such as three, four, or more. Similar expressions (such as at least one, at least one, etc.) are used in the same way. "At least one of the following," "one or more of the following," or similar expressions refer to any combination of these items, which may include only a single item or a combination of multiple items. For example, at least one of a, b, or c can mean: a, or b, or c; a and b; or a and c; or b and c; or a, b, and c. Where a, b, and c can be single or multiple.

[0081] In this application, for the convenience of describing the technical solutions of the embodiments of this application, the terms "first" and "second" may be used to distinguish them. The terms "first" and "second" do not limit the quantity or execution order, and the terms "first" and "second" are not necessarily different.

[0082] In this application, the words "exemplary," "example," or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary," "example," or "for example" should not be construed as being more preferred or advantageous than other embodiments or designs. The use of the words "exemplary," "example," or "for example" is intended to present the relevant concepts in a specific manner to facilitate understanding.

[0083] In this application, "sending information / data" only indicates the direction of information / data transmission, including direct transmission via the device's communication interface (such as an air interface, or simply air interface). "Sending" can also be understood as the "output" of a module interface. "Sending" can include indirect transmission by the processing unit through the communication interface, meaning that after the processing unit outputs information / data through the module interface, it is transmitted to the device's communication interface and then sent out. "Receiving information / data" only indicates the direction of information / data transmission, including direct reception via the communication interface. "Receiving" can also be understood as the "input" of a module interface. "Receiving information / data" can include indirect reception by the processing unit through the communication interface, meaning that after the communication interface receives information / data, it is transmitted to the processing unit's module interface and then input to the processing unit. "Sending information / data to… (such as a terminal)" can be understood as the destination of the information being the terminal. It can include sending information / data directly or indirectly to the terminal. "Receiving information / data from… (such as a terminal)" can be understood as the source of the information being the terminal, and can include receiving information / data directly or indirectly from the terminal. Information / data may undergo necessary processing, such as format changes, between the source and destination, but the destination can understand the valid information / data from the source. Similar statements in this application can be understood in a similar way, and will not be repeated here.

[0084] The technical solutions of this application embodiment can be applied to various communication systems, such as: Long Term Evolution (LTE) systems, 5G (5G) systems, etc. th The solutions provided in this application, including those for generational (5G) communication systems, satellite communication systems, wireless fidelity (WiFi) systems, and others, can also be applied to future communication systems or other communication systems. This application does not limit the scope of these applications.

[0085] Figure 1 is a schematic diagram of the architecture of a communication system applicable to the communication method provided in this application. Figure 1 shows a schematic diagram of a possible, non-limiting system architecture. As shown in Figure 1, the communication system 100 includes a radio access network (RAN) 10 and a core network (CN) 20. Optionally, the communication system 100 also includes the Internet (not shown in Figure 1). The RAN 10 includes at least one RAN node (110a-110c in Figure 1, collectively referred to as 110) and at least one terminal (120a-120j in Figure 1, collectively referred to as 120). The RAN 10 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). The terminal 120 is wirelessly connected to the RAN node 110. The RAN node 110 is wirelessly or wiredly connected to the core network 20. The core network equipment in the core network 20 and the RAN node 110 in the RAN 10 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.

[0086] RAN 10 can support the third-generation partner program (3G). rd RAN 10 can be a cellular system related to the Generation Partnership Project (3GPP), such as 4G, 5G mobile communication systems, or future-oriented evolution systems. RAN 10 can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (Wi-Fi) system. RAN 10 can also be a communication system that integrates two or more of the above systems.

[0087] RAN node 110, sometimes also referred to as access network equipment, RAN entity, or access node, is part of the communication system and is used to help terminals achieve wireless access. Multiple RAN nodes 110 in communication system 100 can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative. For example, network element 120i in Figure 1 can be a non-ground device such as a helicopter or drone, which can be configured as a mobile base station. For terminals 120j accessing RAN 10 through network element 120i, network element 120i is the base station. Network element 110a in Figure 1 can be a non-ground device such as a satellite; for network element 110a, network element 120i is the terminal. RAN node 110 and terminal 120 are sometimes both referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functions, and network elements 120a-120j can be understood as communication devices with terminal functions.

[0088] In one possible scenario, a RAN node can be a base station (BS), an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node can be a macro base station (as shown in Figure 1, 110a), a micro base station or indoor station (as shown in Figure 1, 110b), a relay node or donor node, or a radio controller in a CRAN scenario. Optionally, a RAN node can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0089] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with each RAN node performing a portion of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be separate entities or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0090] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0091] A terminal can also be called a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc.

[0092] In the embodiments of this application, the terminal and network device can be hardware devices, or software functions running on dedicated hardware, or software functions running on general-purpose hardware, such as virtualization functions instantiated on a platform (e.g., cloud platform), or entities that include dedicated or general-purpose hardware devices and software functions. This application does not limit the specific form of the terminal and network device.

[0093] With the continuous development of communication technologies, the Internet of Things (IoT), artificial intelligence (AI), big data, and automation technologies are reshaping traditional industries and giving rise to intelligent applications such as smart cities and autonomous driving. As a crucial infrastructure supporting these emerging intelligent applications, mobile communication systems are gradually evolving into a unified infrastructure of integrated sensing and communication (ISAC), making ISAC technology one of the key potential technologies for future mobile communications.

[0094] In an ISAC system, network devices (such as base stations) possess not only communication capabilities but also sensing capabilities. Sensing capabilities refer to the device's ability to perceive target objects or environmental information via wireless signals, including but not limited to target localization (ranging, velocity, angle measurement, etc.), target imaging, target detection, target tracking, and target recognition. Network devices can be responsible for the centralized storage, management, distribution, and computation of target object or environmental information. Furthermore, terminals in the ISAC system (such as UEs and RSUs), in addition to their communication capabilities, can also assist network devices in providing sensing services (including but not limited to high-precision positioning, high-resolution imaging, and virtual environment reconstruction), and undertake some sensing computation and storage tasks.

[0095] In one implementation, a sensing module with a physical entity can be added to an existing network device or terminal, enabling the existing network device or terminal to have sensing capabilities, thereby providing sensing services to users.

[0096] In one implementation, software algorithms related to sensing services can be added to existing network devices or terminals, and new messages, signaling, flags, or data added to the transmitted air interface data to provide sensing services can be added.

[0097] In addition, the ISAC system may also include a sensing management function (SeMF). The SeMF is primarily responsible for high-level management functions related to sensing services, and its role is similar to that of the location management function (LMF) network element in 5G. This application does not limit the form of the SeMF; the SeMF can be a core network element, a network element mounted on the RAN side, or a dedicated sensing function management module with a physical entity.

[0098] In the process of providing sensing services in an ISAC network, the control of the quality of sensing services (hereinafter referred to as sensing quality) is crucial. Measures such as reasonable network resource allocation, data transmission, and synchronization are used to improve the quality of sensing services. While relevant schemes define sensing quality, which reflects the overall sensing quality of the network, they do not design a detailed and practical sensing quality management scheme.

[0099] To address this issue, embodiments of this application disclose a communication method and a perception quality management scheme that performs perception quality control based on a newly introduced sensing resource mapping scheme (SRMS) level (or perception resource level). In some embodiments, the SRMS level can also be described as an SRMS index.

[0100] Closely related to sensing quality is the amount of time-frequency domain resources occupied by the sensing measurement signal, which includes the number of time-domain symbols and the total frequency-domain bandwidth. The total bandwidth is related to the subcarrier spacing (SCS) and the number of frequency-domain resource blocks (RBs). Therefore, in the communication method shown in this application embodiment, the sensing quality of the ISAC system can be controlled by adjusting the following three physical layer parameters: the number of time-domain symbols of the sensing measurement signal, the number of frequency-domain RBs, and the subcarrier spacing (CSC). The newly introduced SRMS level can be used to indicate the number of symbols, the number of RBs, and the CSC of the sensing measurement signal, as detailed in the following embodiments.

[0101] Furthermore, the communication method illustrated in this application also defines a sensing quality indicator (SQI) level. The SQI level reflects the level of sensing quality, such as spatial accuracy, velocity accuracy, and measurement signal quality, when the current network provides sensing services. Generally, the higher the SQI level, the better the sensing quality of the sensing services provided by the current system. In some embodiments, the SQI level can also be described as an SQI index.

[0102] Referring to Figure 2, the overall process for perceived quality management based on SRMS levels and SQI includes:

[0103] S1, Terminal sensing measurement, to obtain sensing measurement results.

[0104] S2, the terminal determines the SQI level based on the sensing measurement results.

[0105] S3, the terminal reports the SQI level to the network device.

[0106] S4, network devices determine SRMS level based on SQI level.

[0107] S5, the network device adjusts the time-frequency domain resource quantity of the sensing measurement signal based on the SRMS level, and sends the SRMS level to the terminal.

[0108] It should be noted that some steps in the above process can be executed on the terminal device or on the network device. For example, S1-S2 can also be executed by the network device (S3 will not be included in this example). For details, please refer to the detailed embodiments below.

[0109] The communication method for realizing perceived quality management provided in this application will be described in detail below with reference to Figure 3.

[0110] As shown in Figure 3, the communication method includes S301 and S302.

[0111] S301, the network device acquires a first signal quality indication, which is used to indicate the signal quality of the first sensing measurement signal.

[0112] The first sensing measurement signal can be understood as the signal used for sensing measurement in the current network.

[0113] The signal quality of the first sensing measurement signal can be characterized by its measured value. Optionally, the measured value of the first sensing measurement signal includes at least one of the following: signal-to-noise ratio (SNR), signal-to-interference-plus-noise ratio (SINR), reference signal receiving power (RSRP), received signal quality (RSRQ), received signal strength indication (RSSI), delay, or channel quality indication (CQI). For example, taking the measured value of the first sensing measurement signal as SINR, the higher the SINR of the first sensing measurement signal, the better the signal quality of the first sensing measurement signal.

[0114] In some embodiments, the first signal quality indicator may also be described as a first perceived quality indicator (first SQI).

[0115] In some embodiments, the first signal quality indicator may be an index of the first signal quality indicator. The index of the first signal quality indicator is used to indicate the signal quality of the first sensing measurement signal, and also to indicate the amount of time-domain resources and / or frequency-domain resources used by the first sensing measurement signal.

[0116] In one example, the index of the first signal quality indicator includes a first index, which indicates the amount of time-domain resources and frequency-domain resources used by the first sensing measurement signal. The first index of the first signal quality indicator may be denoted as the first SQI index.

[0117] In one example, the index of the first signal quality indicator includes a second index and / or a third index. The second index indicates the amount of time-domain resources used by the first sensing measurement signal, and the third index indicates the amount of frequency-domain resources used by the first sensing measurement signal. The second index of the first signal quality indicator can be denoted as the first SQI-T (sensing quality indicator-time) index, and the third index of the first signal quality indicator can be denoted as the first SQI-F (sensing quality indicator-frequecy) index.

[0118] In S301, the first sensing measurement signal can be a sensing measurement signal sent from the network device to the terminal device. The network device obtains a first signal quality indication from the terminal device. The first signal quality indication is determined by the terminal device based on the measurement result of the first sensing measurement signal. Alternatively, the first sensing measurement signal can be a sensing measurement signal sent from the terminal device to the network device. The network device obtains the first signal quality indication based on the measurement result of the first sensing measurement signal. Several implementations of S301 will be described below with reference to Figures 4 and 5.

[0119] In embodiment 1 of S301, referring to FIG4, S301 includes S401-S402:

[0120] S401, the network device sends the first sensing measurement signal to the terminal device.

[0121] S402, the terminal device sends a first signal quality indication to the network device.

[0122] In one example, after receiving a first sensing measurement signal from a network device, the terminal device determines a first signal quality indication based on the first sensing measurement signal. Specifically, the terminal device determines a first sensing measurement result based on the first sensing measurement signal, and then determines the first signal quality indication based on the first sensing measurement result and a fourth mapping relationship. After determining the first signal quality indication, the terminal device sends the first signal quality indication to the network device so that the network device is aware of the first signal quality indication.

[0123] The first sensing measurement result is used to indicate the measured value of the first sensing measurement signal.

[0124] The fourth mapping relationship is used to indicate the mapping relationship between the measured values ​​of multiple sensing measurement signals and multiple signal quality indicators. It should be noted that the fourth mapping relationship can be constructed through extensive pre-testing (see steps a to d below). The form of the fourth mapping relationship includes, but is not limited to, tables, formulas, or functions. For example, the formula for the fourth mapping relationship f is expressed as follows: I SQI =f(N) symbols ,Bandwidth,SensingMeasurements)

[0125] In the formula, I SQI N represents the index value indicating the signal quality of the sensed measurement signal. symbols This represents the number of symbols used for sensing measurements, Bandwidth represents the total bandwidth used for sensing measurements, and SensingMeasurements represents the measured values ​​of the sensing measurement signal.

[0126] The process of constructing the fourth mapping relationship will be explained in detail below, taking the measured value of the sensing measurement signal SINR as an example.

[0127] The process of constructing the fourth mapping relationship includes:

[0128] Step a: Preset the network's sensing accuracy. For example, taking meter-level accuracy as an example, set the target threshold T for the sensing accuracy. Acc It equals 1 meter.

[0129] Step b involves setting a set of time-frequency domain resource quantities, such as setting a set of time-domain symbol counts and frequency-domain bandwidths, and setting a SQI (e.g., SQI level or SQI index) corresponding to this set of time-frequency domain resource quantities. Then, sensing measurements are performed on the sensing measurement signals of these time-frequency domain resources.

[0130] Step c: Adjust the intensity of the sensing measurement signal to achieve the target threshold for sensing accuracy (e.g., T). Acc The SINR of the sensing measurement signal when the distance is equal to 1 meter is used to construct a mapping relationship between SQI and SINR.

[0131] Step d: Reset a set of time-frequency domain resource quantities and the SQI corresponding to this set of time-frequency domain resource quantities. Repeat steps b to c above to build another set of SQI-SINR mapping relationships until the SINR corresponding to all SQIs is calibrated.

[0132] It should be noted that the number of SQIs in the fourth mapping is predefined and related to the number of bits occupied by each SQI. In one example, if SQI occupies n bits, then the number of SQI indices in the fourth mapping is 2. n For example, if SQI occupies 4 bits, then the maximum number of SQI indices in the fourth mapping relationship can be 16 (i.e., 2^35). 4 SQI has 16 selectable levels.

[0133] It should be noted that after the fourth mapping relationship is constructed, it can be stored in the network device and / or terminal device so that the network device or terminal device can determine the SQI corresponding to the measured value of the sensed measurement signal (such as SINR) based on the fourth mapping relationship.

[0134] In embodiment 2 of S301, referring to Figure 5, S301 includes S501-S502:

[0135] S501, the terminal device sends the first sensing measurement signal to the network device.

[0136] S502, the network device determines a first signal quality indication based on the first sensing measurement signal.

[0137] After receiving the first sensing measurement signal from the terminal device, the network device determines the first sensing measurement result based on the first sensing measurement signal. Based on the first sensing measurement result and the fourth mapping relationship, the network device determines the first signal quality indication.

[0138] The first sensing measurement result indicates the measured value of the first sensing measurement signal. The fourth mapping relationship indicates the mapping relationship between the measured values ​​of multiple sensing measurement signals and multiple signal quality indicators.

[0139] In this embodiment, the implementation principle of the network device determining the first signal quality indication based on the first sensing measurement signal is similar to that of the terminal device in Embodiment 1 of S301, and can be referred to Embodiment 1 of S301, which will not be repeated here.

[0140] S302, the network device sends the first information based on the first signal quality indication.

[0141] The first information is used to indicate the time-domain information and / or frequency-domain information used for sensing measurements.

[0142] Optionally, the first information includes at least one of the following: first resource index information, first time-domain resource quantity, or first frequency-domain resource quantity. The first resource index information is used to indicate the first time-domain resource quantity and / or the first frequency-domain resource quantity used for sensing measurements. In some embodiments, the first resource index information may also be described as first sensing resource index information.

[0143] For example, the first time-domain resource quantity includes the number of symbols, and the first frequency-domain resource quantity includes the total bandwidth.

[0144] In one example, the first information includes first resource index information.

[0145] In one example, the first information includes a first time-domain resource quantity and a first frequency-domain resource quantity.

[0146] In one example, the first information includes first resource index information, first time-domain resource quantity, and first frequency-domain resource quantity.

[0147] In one example, the first information includes the first time-domain resource quantity.

[0148] In one example, the first information includes the amount of first frequency domain resources.

[0149] It should be noted that, in the embodiments of this application, the time-domain resource quantity includes, but is not limited to, the number of time-domain symbols, time units, time length, symbol interval, etc. The symbol interval can be understood as the frequency at which a sensing measurement signal is sent once every certain number of symbols; for example, a symbol interval of 5 means that a sensing measurement signal is sent once every 5 symbols. The frequency-domain resource quantity includes, but is not limited to, the number of frequency-domain redundancies (RBs), or the frequency-domain density, or the total frequency-domain bandwidth.

[0150] In some embodiments, the first information includes first resource index information, which includes a first resource index. The first resource index is used to indicate a first time-domain resource quantity and a first frequency-domain resource quantity. In this embodiment, the first resource index information includes only one resource index, which simultaneously indicates a set of time-frequency domain resource quantities.

[0151] In some embodiments, the first information includes first resource index information, which includes a first time-domain resource index and / or a first frequency-domain resource index.

[0152] In one example, the first resource index information includes a first time-domain resource index, which indicates a first time-domain resource quantity used for sensing measurements. Exemplarily, the first time-domain resource quantity can be a symbol number. In some embodiments, the first resource index information can also be described as first sensing resource index information. The first time-domain resource index can also be described as a first time-domain sensing resource mapping scheme-time (SRMS-T) index.

[0153] In one example, the first resource index information includes a first frequency domain resource index, which indicates the amount of first frequency domain resources used for sensing measurements. For example, the amount of first frequency domain resources may be total bandwidth, number of redundancies (RBs), or frequency density, etc. In some embodiments, the first frequency domain resource index may also be described as a first frequency domain sensing resource mapping scheme-frequency (SRMS-F) index.

[0154] In one example, the first resource index information includes a first time-domain resource index and a first frequency-domain resource index.

[0155] In S302, the network device can determine first information based on a first signal quality indication and one or more pre-existing mapping relationships (such as the first mapping relationship below) within the network device (such as the second and third mapping relationships below). This first information indicates the time-domain and / or frequency-domain information required for sensing measurements. The network device can also determine the required time-domain and / or frequency-domain information (such as the second time-domain resource quantity and the second frequency-domain resource quantity below) for sensing measurements based on the first signal quality indication and a pre-existing mapping relationship (such as the second mapping relationship below), and obtain the network-configured time-domain and / or frequency-domain information for sensing measurements from the first network element through interaction with the first network element. Alternatively, the network device can directly send the first signal quality indication to the first network element, which will then configure the time-domain and / or frequency-domain information for sensing measurements. Several implementations of S302 are described below with reference to Figures 6 to 9.

[0156] In embodiment 1 of S302, referring to FIG6, S302 includes S601-S602:

[0157] S601, the network device determines the first time-domain resource quantity and the first frequency-domain resource quantity based on the first signal quality indication and the first mapping relationship.

[0158] The first mapping relationship is used to indicate the mapping relationship between the first signal quality indicator and the first time-frequency domain information. The first time-frequency domain information includes the first time-domain resource quantity and the first frequency-domain resource quantity. The first time-frequency domain information is used for sensing and measurement.

[0159] It should be noted that the first mapping relationship is predefined and is stored in the network device and / or terminal device beforehand. The form of the first mapping relationship includes, but is not limited to, tables, formulas, or functions.

[0160] For example, taking the first mapping relationship as a table, the number of SQI indices in the first mapping relationship is related to the number of bits occupied by SQI. In one example, SQI occupies n bits (n is a positive integer), then the number of SQI indices in the first mapping relationship is 2. n For example, if SQI occupies 4 bits, then the number of SQI indices in the first mapping is 16 (i.e., 2^35). 4 That is, SQI has 16 selectable levels. Table 1 shows a first mapping relationship, which includes multiple sets of Signal Quality Indicator (SQI) indices and first time-frequency domain information (number of symbols (N)). symbols The mapping relationship between time-domain resources and total bandwidth is shown in Table 1. It should be noted that Table 1 uses the time-domain resources as the number of symbols and the frequency-domain resources as the total bandwidth as an example to illustrate the first mapping relationship. In reality, other parameters may be used to represent the time-frequency domain resources.

[0161] Table 1

[0162] For example, suppose the network device obtains a first signal quality indicator with an SQI index of 6, and the network device determines the first time domain resource quantity as 84 symbols and the first frequency domain resource quantity as 140MHz total bandwidth based on the first mapping relationship shown in Table 1.

[0163] The network device determines the first time-domain resource quantity and the first frequency-domain resource quantity based on the first signal quality indication and the first mapping relationship. The first time-domain resource quantity and the first frequency-domain resource quantity are used for sensing measurement.

[0164] S602, the network device sends first information to the terminal device, the first information including the first time domain resource quantity and the first frequency domain resource quantity.

[0165] In the above-described S302 implementation 1, the network device obtains a first signal quality indication and, in conjunction with a preset first mapping relationship, determines a set of time-frequency domain resource quantities (first time-domain resource quantity and first frequency-domain resource quantity) corresponding to the first signal quality indication. The network device then sends this set of time-frequency domain resource quantities to the terminal device for sensing and measurement.

[0166] By implementing this solution, flexible control of the time-frequency domain resources of sensing measurement signals can be achieved at the physical layer, thereby enabling real-time regulation of sensing quality by the network and improving the quality of sensing services.

[0167] In embodiment 2 of S302, referring to FIG7, S302 includes S701-S703:

[0168] S701, the network device determines the second time-domain resource quantity and the second frequency-domain resource quantity based on the first signal quality indication and the second mapping relationship.

[0169] The second mapping relationship is used to indicate the mapping relationship between the first signal quality indication and the second time-frequency domain information. The second time-frequency domain information includes the second time-domain resource quantity and the second frequency-domain resource quantity. The second time-frequency domain information is used for sensing and measurement.

[0170] It should be noted that the second mapping relationship is predefined and pre-stored in the network device and / or terminal device. The form of the second mapping relationship includes, but is not limited to, tables, formulas, or functions.

[0171] The second mapping relationship will be introduced below with three examples.

[0172] In one example, the second mapping includes multiple signal quality indicator indices (multiple SQI indices), each corresponding to a number of symbols and a total bandwidth. These multiple signal quality indicator indices include a first index of a first signal quality indicator. The first index of the first signal quality indicator is used to indicate the amount of time-frequency domain resources (such as the number of symbols and total bandwidth) used by the first sensing measurement signal. In this example, one signal quality indicator index in the second mapping simultaneously indicates a set of time-frequency domain resources used for sensing measurements.

[0173] For example, taking the second mapping relationship as a table, the number of SQI indices in the second mapping relationship is related to the number of bits occupied by SQI. In one example, if SQI occupies n bits, then the number of SQI indices in the second mapping relationship is 2. n For example, if SQI occupies 4 bits, then the number of SQI indices in the second mapping is 16 (i.e., 2^35). 4 This means that SQI has 16 selectable levels. The second mapping relationship can be found in Table 1.

[0174] For example, suppose the first index of the first signal quality indicator obtained by the network device is SQI of 4, and the network device determines the second time domain resource quantity as the number of symbols of 28 and the second frequency domain resource quantity as the total bandwidth of 80MHz based on the second mapping relationship shown in Table 1.

[0175] In one example, the second mapping relationship includes multiple second signal quality indicator indices, multiple third signal quality indicator indices, the number of symbols corresponding to each second signal quality indicator index, and the total bandwidth corresponding to each third signal quality indicator index. The multiple second signal quality indicator indices include second indices of a first signal quality indicator, and the multiple third signal quality indicator indices include third indices of a first signal quality indicator. Specifically, the second indices of the first signal quality indicator are used to indicate the amount of time-domain resources (e.g., the number of symbols) used by the first sensing measurement signal, and the third indices of the first signal quality indicator are used to indicate the amount of frequency-domain resources (e.g., the total bandwidth) used by the first sensing measurement signal.

[0176] In this example, the signal quality indicator index in the second mapping relationship includes two types. One type is the second signal quality indicator index, which is used to indicate the amount of time-domain resources (such as the number of symbols) used for sensing measurements. The second signal quality indicator index can be denoted as the SQI-T index. The other type is the third signal quality indicator, which is used to indicate the amount of frequency-domain resources (such as total bandwidth, number of RBs, or frequency density) used for sensing measurements. The third signal quality indicator index can be denoted as the SQI-F index.

[0177] For example, taking the second mapping relationship as a table, the number of SQI-T indices in the second mapping relationship is related to the number of bits occupied by SQI-T, and the number of SQI-F indices is related to the number of bits occupied by SQI-F. The number of bits occupied by SQI-T and SQI-F can be the same or different. Below, we take an example where both SQI-T and SQI-F occupy 4 bits each. The second mapping relationship includes two tables, denoted as the SQI-T table and the SQI-F table respectively.

[0178] Table 2 shows a SQI-T table, which includes multiple sets of mappings between Second Signal Quality Indicator (SQI-T) indices and the number of symbols. Table 3 shows a SQI-F table, which includes multiple sets of mappings between Third Signal Quality Indicator (SQI-F) indices and the total bandwidth. It should be noted that Table 2 illustrates the SQI-T table in the second mapping relationship using time-domain resources as the number of symbols; however, other parameters may actually represent the time-domain resources. Table 3 illustrates the SQI-F table in the second mapping relationship using frequency-domain resources as the total bandwidth; however, other parameters may also represent the frequency-domain resources.

[0179] Table 2

[0180] Table 3

[0181] For example, suppose the index for the network device to obtain the first signal quality indication includes a first SQI-T index of 6 and a first SQI-F index of 7. Based on the SQI-T table shown in Table 2, the network device determines the second time domain resource quantity as 84 symbols. Based on the SQI-F table shown in Table 3, the network device determines the second frequency domain resource quantity as 180MHz total bandwidth.

[0182] In one example, the second mapping relationship includes a third function and a fourth function, wherein the third function indicates the mapping relationship between the second signal quality indicator and the number of symbols, and the fourth function indicates the mapping relationship between the third signal quality indicator and the total bandwidth.

[0183] For example, the third function can be represented as N Symbols =g3(I SQI-T )=a·I SQI-T The fourth function can be expressed as Bandwidth = g4(I SQI-F )=b·I SQI-F Where g3(x) represents the third function, I SQI-T Represents the index value of SQI-T, g4(x) represents the fourth function, I SQI-FThis represents the SQI-F index value. a and b are preset values, for example, a is 12 and b is 40MHz.

[0184] In the above examples, g3(x) and g4(x) are both formulas expressing a linear mapping relationship. It should be noted that the definitions of g3(x) and g4(x) in this application embodiment are not limited.

[0185] Based on the three examples above, it can be seen that when a network device obtains a first signal quality indication, it can determine a set of time-frequency domain resources (second time-domain resources and second frequency-domain resources) corresponding to the first signal quality indication by combining the second mapping relationship shown in any of the above examples (such as Table 1, or Table 2 and Table 3, or g3(x) and g4(x)). This set of time-frequency domain resources can be regarded as the time-frequency domain resources required for sensing measurement.

[0186] S702, the network device determines the first resource index information based on the second time domain resource quantity, the second frequency domain resource quantity, and the third mapping relationship.

[0187] The third mapping relationship is used to indicate the mapping relationship between the first resource index information and the third time-frequency domain information, which is used for sensing and measurement. The third time-frequency domain information includes the third time-domain resource quantity and the third frequency-domain resource quantity.

[0188] In one example, the third time-domain resource quantity is equal to the second time-domain resource quantity, and the third frequency-domain resource quantity is equal to the second frequency-domain resource quantity. For example, suppose the network device determines, through the second mapping relationship shown in Table 1, that the second time-domain resource quantity is 28 symbols and the second frequency-domain resource quantity is 80MHz total bandwidth. The third mapping relationship shown in Table 6 includes this set of second time-frequency domain information; therefore, the third time-domain resource quantity is 28 symbols and the third frequency-domain resource quantity is 80MHz total bandwidth. Based on the third time-domain resource quantity and the third frequency-domain resource quantity, and the third mapping relationship shown in Table 6, the network device determines the first resource index information as having a first resource index (SRMS index) of 8.

[0189] In one example, the third time-domain resource quantity is equal to the second time-domain resource quantity, but the third frequency-domain resource quantity is not equal to the second frequency-domain resource quantity (or described as the third frequency-domain resource quantity not being the second frequency-domain resource quantity). For example, suppose the network device determines, through the second mapping relationship shown in Table 1, that the second time-domain resource quantity is 28 symbols and the second frequency-domain resource quantity is 80MHz total bandwidth. The third mapping relationship shown in Table 7 does not include this set of second time-frequency domain information; therefore, the third time-domain resource quantity is 28 symbols and the third frequency-domain resource quantity is 144 RBs. Based on the third time-domain resource quantity and the third frequency-domain resource quantity, and the third mapping relationship shown in Table 7, the network device determines the first resource index information as 11 for the first resource index (SRMS index).

[0190] It should be noted that the third mapping relationship is predefined and pre-stored in network devices and / or terminal devices. The form of the third mapping relationship includes, but is not limited to, tables, formulas, or functions.

[0191] The third mapping relationship will be introduced below with four examples.

[0192] In one example, the third mapping relationship includes multiple time-domain resource indices and multiple frequency-domain resource indices, the number of symbols corresponding to each time-domain resource index, and the total bandwidth corresponding to each frequency-domain resource index. The multiple time-domain resource indices include a first time-domain resource index, and the multiple frequency-domain resource indices include a first frequency-domain resource index.

[0193] In this example, the resource indexes in the third mapping relationship include two types: one is the time-domain resource index (which can be denoted as SRMS-T), where one time-domain resource index corresponds to one time-domain resource quantity (such as the number of symbols); the other is the frequency-domain resource index (which can be denoted as SRMS-F), where one frequency-domain resource index corresponds to one frequency-domain resource quantity (such as the total bandwidth).

[0194] For example, taking the third mapping relationship as a table, the number of SRMS-T indices in the third mapping relationship is related to the number of bits occupied by SRMS-T, and the number of SRMS-F indices is related to the number of bits occupied by SRMS-F. The number of bits occupied by SRMS-T and SRMS-F can be the same or different. Below, we take an example where both SRMS-T and SRMS-F occupy 5 bits each. The third mapping relationship includes two tables, denoted as the SRMS-T table and the SRMS-F table, respectively.

[0195] Table 4 shows an SRMS-T table, which includes a mapping relationship between multiple sets of time-domain resource indices (SRMS-T) and the number of symbols. Table 5 shows an SRMS-F table, which includes a mapping relationship between multiple sets of frequency-domain resource indices (SRMS-F) and the total bandwidth.

[0196] It should be noted that Table 4 uses time-domain resource quantity as the sign number as an example to illustrate the SRMS-T table in the third mapping relationship. In reality, other parameters may also represent the time-frequency resource quantity. Table 5 uses frequency-domain resource quantity as the total bandwidth as an example to illustrate the SRMS-F table in the third mapping relationship. In reality, other parameters may also represent the frequency-domain resource quantity.

[0197] Table 4

[0198] Table 5

[0199] For example, assuming the network device determines the second time-domain resource quantity based on S701 as having 84 symbols and the second frequency-domain resource quantity as having a total bandwidth of 140MHz, the network device determines that the SRMS-T index includes 11 and 12 based on the SRMS-T table shown in Table 4. The network device determines that the SRMS-F index is 12 based on the SRMS-F table shown in Table 5. The first resource index information determined by the network device includes: the first time-domain resource index (SRMS-T index is 11 or 12) and the first frequency-domain resource index (SRMS-F index is 12).

[0200] In one example, the third mapping relationship includes a first function and a second function, the first function indicating the mapping relationship between the time-domain resource index and the number of symbols, and the second function indicating the mapping relationship between the frequency-domain resource index and the total bandwidth.

[0201] For example, the first function can be represented as N Symbols =g1(I SRMS-T )=α·I SRMS-T The second function can be expressed as Bandwidth = g2(I SRMS-F )=β·I SRMS-F Where g1(x) represents the first function, I SRMS-T Represents the index value of SRMS-T, g2(x) represents the second function, I SRMS-F This represents the index value of SRMS-F. α and β are preset values, for example, α is 4 and β is 25MHz.

[0202] In the above examples, g1(x) and g2(x) are both formulas expressing a linear mapping relationship. It should be noted that the definitions of g1(x) and g2(x) in this application embodiment are not limited.

[0203] The network device determines the number of symbols corresponding to the first time-domain resource index based on the first time-domain resource index and the first function; and determines the total bandwidth corresponding to the first frequency-domain resource index based on the first frequency-domain resource index and the second function.

[0204] In one example, the third mapping relationship includes multiple resource indices, each corresponding to a number of symbols and a total bandwidth. In this example, one resource index in the third mapping relationship simultaneously corresponds to a set of time-frequency domain resources.

[0205] For example, taking the third mapping relationship as a table, the number of SRMS indices in the third mapping relationship is related to the number of bits occupied by SRMS. In one example, SRMS occupies m bits (m is a positive integer), then the number of SRMS indices in the third mapping relationship is 2. mFor example, if SRMS occupies 5 bits, then the number of SRMS indices in the third mapping is 32 (i.e., 2^32). 5 SRMS has 32 selectable levels. Table 6 shows a third mapping relationship, which includes the mapping relationship between multiple sets of resource indices (SRMS indices) and third time-frequency domain information (number of symbols and total bandwidth). It should be noted that Table 6 uses the number of symbols as the time-domain resource quantity and the total bandwidth as the frequency-domain resource quantity as an example to illustrate the third mapping relationship. In reality, other parameters may also be used to represent the time-frequency domain resource quantity.

[0206] Table 6

[0207] For example, assuming the network device determines the second time-domain resource quantity based on S701 as having 84 symbols and the second frequency-domain resource quantity as having a total bandwidth of 140MHz, the network device determines the SRMS index as 12 based on the SRMS table shown in Table 6. The first resource index information determined by the network device includes the first resource index (the first SRMS index is 12).

[0208] In one example, the third mapping relationship includes multiple mapping tables, each mapping table corresponding to a subcarrier interval, each mapping table including multiple resource indices, and the number of symbols and resource blocks corresponding to each resource index.

[0209] Optionally, the subcarrier spacing includes three subcarrier spacings applicable to frequency range 1 (FR1), namely 15 kHz, 30 kHz and 60 kHz.

[0210] Optionally, the subcarrier spacing includes three subcarrier spacings applicable to frequency range 2 (FR2), namely 60 kHz, 120 kHz and 240 kHz.

[0211] Optionally, the subcarrier spacing includes two additional subcarrier spacings introduced in R17 that are applicable to FR2, namely 480kHz and 960kHz.

[0212] Because the maximum number of symbols per radio frame specified in the protocol differs under different subcarrier intervals, the bandwidth limit also differs for different subcarrier intervals. Therefore, corresponding SRMS tables can be configured for the aforementioned different subcarrier intervals. It can be understood that when the network sets a certain subcarrier interval, it can determine the SRMS level by querying the predefined SRMS table corresponding to that subcarrier interval, and perform sensing measurements based on the time-frequency domain resource quantity corresponding to the SRMS level.

[0213] Tables 7 to 14 show eight SRMS tables, each corresponding to a subcarrier interval. Each SRMS table includes multiple sets of resource indices (SRMS indices) and mapping relationships with third time-frequency domain information (number of symbols and number of resource blocks (RBs)). It should be noted that Tables 7 to 14 illustrate multiple mapping tables with the time-domain resource quantity represented by the number of symbols and the frequency-domain resource quantity represented by the number of RBs, but in reality, other parameters may be used to represent the time-frequency domain resource quantity.

[0214] Table 7. SRMS table corresponding to SCS at 15kHz

[0215] For example, suppose the network device determines the second time-domain resource quantity based on S701 to be 84 symbols and the second frequency-domain resource quantity to be a total bandwidth of 140MHz, and the network sets the subcarrier spacing (SCS) to be 15kHz. Based on the SRMS table shown in Table 7, the network device determines that the SRMS index corresponding to the symbol quantity of 84 is 17, 18, 19, or 20. The first resource index information determined by the network device includes the first resource index (SRMS index is 17, 18, 19, or 20). This example does not limit the first resource index; the SRMS index can be greater than or equal to 17.

[0216] Table 8. SRMS table corresponding to SCS at 30kHz

[0217] For example, suppose the network device determines the second time-domain resource quantity based on S701 to be 84 symbols and the second frequency-domain resource quantity to be a total bandwidth of 140MHz, and the network sets the subcarrier spacing (SCS) to be 30kHz. Based on the SRMS table shown in Table 8, the network device determines that the SRMS index corresponding to the symbol quantity of 84 is 13 or 14. The first resource index information determined by the network device includes the first resource index (SRMS index is 13 or 14). This example does not limit the first resource index; the SRMS index can be greater than or equal to 13.

[0218] Table 9. SRMS table corresponding to SCS at 60kHz (FR1)

[0219] For example, assuming the network device determines the second time-domain resource quantity based on S701 as 84 symbols and the second frequency-domain resource quantity as a total bandwidth of 140MHz, and the network sets the subcarrier spacing (SCS) to 60kHz (FR1), the network device determines the SRMS index corresponding to the symbol quantity 84 as 11 or 12 based on the SRMS table shown in Table 9. The first resource index information determined by the network device includes the first resource index (SRMS index is 11 or 12). This example does not limit the first resource index; the SRMS index can be greater than or equal to 11.

[0220] Table 10 SRMS table corresponding to SCS at 60kHz (FR2)

[0221] For example, assuming the network device determines the second time-domain resource quantity based on S701 to be 84 symbols and the second frequency-domain resource quantity to be a total bandwidth of 140MHz, and the network sets the subcarrier spacing (SCS) to 60kHz (FR2), the network device, based on the SRMS table shown in Table 10, determines that the first resource index can be an SRMS index of 10, 11, or 12, etc., that is, it can choose any SRMS index in Table 10 corresponding to a symbol quantity greater than 84. In this example, the first resource index is not limited; the SRMS index can be greater than or equal to 10.

[0222] Table 11 SRMS Table for SCS at 120kHz

[0223] For example, suppose the network device determines the second time-domain resource quantity based on S701 as having a symbol count of 210, and the second frequency-domain resource quantity as having a total bandwidth of 320MHz. Furthermore, the network sets the subcarrier spacing (SCS) to 120kHz. Based on the SRMS table shown in Table 11, the network device determines that the first resource index can be an SRMS index of 7, 8, or 9, meaning it can select any SRMS index in Table 11 corresponding to a symbol count greater than 210. In this example, the first resource index is not limited; an SRMS index greater than or equal to 7 is acceptable.

[0224] Table 12 SRMS table corresponding to SCS at 240kHz

[0225] For example, assuming the network device determines the second time-domain resource quantity based on S701 to be 210 symbols and the second frequency-domain resource quantity to be a total bandwidth of 320MHz, and the network sets the subcarrier spacing (SCS) to be 240kHz, the network device, based on the SRMS table shown in Table 12, determines that the first resource index can be an SRMS index of 5, 6, or 7, that is, it can select the SRMS index corresponding to a symbol quantity greater than 210 in Table 12. In this example, the first resource index is not limited; the SRMS index can be greater than or equal to 5.

[0226] Table 13 SRMS Table for SCS at 480kHz

[0227] For example, suppose the network device determines the second time-domain resource quantity based on S701 to be 2^10 symbols and the second frequency-domain resource quantity to be 320MHz total bandwidth, and the network sets the subcarrier spacing (SCS) to be 480kHz. Based on the SRMS table shown in Table 13, the network device determines that the first resource index can be an SRMS index of 3, 4, or 5, that is, it can select the SRMS index corresponding to a symbol quantity greater than 2^10 in Table 13. In this example, the first resource index is not limited, and the SRMS index can be greater than or equal to 3.

[0228] Table 14 SRMS Table for SCS at 960kHz

[0229] For example, suppose the network device determines the second time-domain resource quantity based on S701 to have a symbol count of 2^10 and the second frequency-domain resource quantity to have a total bandwidth of 320MHz. Furthermore, the network sets the subcarrier spacing (SCS) to 960kHz. Based on the SRMS table shown in Table 14, the network device determines that the first resource index can be an SRMS index of 2, 3, or 4, i.e., it can select the SRMS index corresponding to a symbol count greater than 2^10 in Table 14. In this example, the first resource index is not limited; an SRMS index greater than or equal to 2 is acceptable.

[0230] Among the eight SRMS tables shown in Tables 7 to 14 above, the SRMS index can also have two types: SRMS-T index and SRMS-F index. Accordingly, each of the eight SRMS tables can be split into two tables (SRMS-T table and SRMS-F table) with separate time-frequency domain resources, which will not be elaborated here.

[0231] S703, the network device sends first information to the terminal device, the first information including first resource index information.

[0232] In embodiment 2 of S302 described above, the network device acquires a first signal quality indication and, in conjunction with a preset second mapping relationship, first determines a set of time-frequency domain resource quantities (second time-domain resource quantities and second frequency-domain resource quantities) corresponding to the first signal quality indication. The network device then, in conjunction with a preset third mapping relationship, determines the first resource index information corresponding to this set of time-frequency domain resource quantities. The network device sends the first resource index information to the terminal device, enabling the terminal device to perform sensing measurements based on the time-frequency domain resource quantities indicated by the first resource index information.

[0233] By implementing this solution, flexible control of the time-frequency domain resources of sensing measurement signals can be achieved at the physical layer, thereby enabling real-time regulation of sensing quality by the network and improving the quality of sensing services.

[0234] In embodiment 3 of S302, referring to Figure 8, S302 includes S801-S804:

[0235] S801, the network device determines the second time-domain resource quantity and the second frequency-domain resource quantity based on the first signal quality indication and the second mapping relationship.

[0236] S801 in this embodiment is similar to S701 in the previous text. For details, please refer to the previous text. It will not be repeated here.

[0237] S802, the network device sends second information to the first network element, the second information including the second time domain resource quantity and the second frequency domain resource quantity.

[0238] S803, the first network element sends third information to the network device, the third information including the first resource index information.

[0239] After receiving the second information from the network device, the first network element determines the first resource index information based on the second time-domain resource quantity and the second frequency-domain resource quantity in the second information, combined with the third mapping relationship. Specifically, the first network element allocates an upper limit of time-frequency domain resources for sensing and measurement according to the available time-frequency domain resources of the current system, and then determines the first resource index information by combining the third mapping relationship. The first resource index information includes a first time-domain resource index and / or a first frequency-domain resource index.

[0240] For ease of description, let's denote the second time-domain resource quantity in the second information as X. T The second frequency domain resource quantity is denoted as X. F The first network element obtains the amount of available time-frequency resources Y in the current system. T Frequency domain resource quantity Y F Taking time-domain resource allocation as an example, the first network element to X T and Y T Make a judgment:

[0241] In one example, if XT Less than or equal to Y T This indicates that the current system's time-domain resources can meet the time-domain resource requirements for sensing and measurement. The first network element is based on X. T And the third mapping relationship, determining that the amount of time-domain resources does not exceed X. T The largest time-domain resource index is used as the final time-domain resource index. For example, taking the third mapping relationship as Table 4, assume the second time-domain resource quantity X... T Given a sign number of 8, the available time-domain resources Y of the current system T If the symbol count is 28, then the first network element is based on Table 4 and X. T The largest SRMS-T index with no more than 8 symbols is determined as the final time-domain resource index, that is, the first time-domain resource index is the SRMS-T index with a value of 4.

[0242] In one example, if X T Greater than Y T This indicates that the current system's time-domain resources are insufficient to meet the time-domain resource requirements for sensing and measurement. The higher-level network is based on Y... T And the third mapping relationship, determining that the amount of time-domain resources does not exceed Y. T The largest frequency domain resource index is used as the final frequency domain resource index. For example, taking the third mapping relationship as shown in Table 4, assume the second time domain resource quantity X... T Given a symbol count of 56, the available time-domain resources Y of the current system. T If the symbol count is 14, then the first network element is based on Table 4 and Y. T The largest SRMS-T index with no more than 14 symbols is determined as the final time-domain resource index, that is, the first time-domain resource index is the SRMS-T index with a value of 6.

[0243] The principle of allocating frequency domain resources can be referred to the principle of allocating time domain resources, and will not be elaborated here.

[0244] After determining the first resource index information, the first network element sends third information to the network device, which includes the first resource index information.

[0245] S804, the network device sends first information to the terminal device, the first information including first resource index information.

[0246] In some embodiments, after receiving the third information, the network device determines the first time-domain resource quantity and the first frequency-domain resource quantity corresponding to the first resource index information based on the third mapping relationship. The network device then sends the first information to the terminal device. The first information includes the first resource index information, the first time-domain resource quantity, and the first frequency-domain resource quantity.

[0247] In this embodiment, the network device obtains a first signal quality indicator and, in conjunction with a preset second mapping relationship, determines a set of time-frequency domain resources (second time-domain resources and second frequency-domain resources) corresponding to the first signal quality indicator. This set of time-frequency domain resources represents the required time-frequency domain resources. The network device sends this set of time-frequency domain resources to a first network element, which then determines the upper limit of the time-frequency domain resources that can be allocated. The first network element then sends the first resource index information corresponding to the upper limit of the allocated time-frequency domain resources to the network device, enabling real-time control of the perceived quality by the network to improve the perceived service quality.

[0248] In some embodiments, the first network element allocates an upper limit of time-frequency domain resources for sensing measurements, namely, the first time-domain resource quantity and the first frequency-domain resource quantity, based on the second time-domain resource quantity and the second frequency-domain resource quantity in the second information, as well as the time-frequency domain resources currently available in the system. The first network element sends third information to the network device, the third information including the first time-domain resource quantity and the first frequency-domain resource quantity.

[0249] In some embodiments, the third information includes first resource index information, first time-domain resource quantity, and first frequency-domain resource quantity.

[0250] In embodiment 4 of S302, referring to FIG9, S302 includes S901, S902 and S903 (S903a-S905a, or S903b-S905b).

[0251] S901, the network device sends second information to the first network element, the second information including the first signal quality indication.

[0252] S902, the first network element determines the second time-domain resource quantity and the second frequency-domain resource quantity based on the first signal quality indication and the second mapping relationship.

[0253] The implementation principle of S902 is similar to that of S701 mentioned above, and can be referred to S701, so it will not be repeated here.

[0254] In one example, after S902, it includes:

[0255] S903a, the first network element determines the first resource index information based on the second time domain resource quantity, the second frequency domain resource quantity, and the third mapping relationship.

[0257] S905a, the network device sends first information to the terminal device, the first information including first resource index information.

[0258] The implementation principle of S903a is similar to that of S803 mentioned above, and will not be repeated here.

[0259] In one example, after S902, it includes:

[0260] S903b, the first network element allocates an upper limit of time-frequency domain resources for sensing and measurement based on the second time-domain resource quantity, the second frequency-domain resource quantity, and the time-frequency domain resources currently available in the system, that is, determines the first time-domain resource quantity and the first frequency-domain resource quantity.

[0261] S904b: The first network element sends third information to the network device. The third information includes the first time domain resource quantity and the first frequency domain resource quantity.

[0263] In some embodiments, the third information includes first resource index information, first time-domain resource quantity, and first frequency-domain resource quantity.

[0264] In embodiments 3 and 4 of S302 above, after the network device obtains the first signal quality indication or the amount of time-frequency domain resources (second time-domain resources and second frequency-domain resources) required for sensing measurement, it can interact with the first network element to obtain the latest amount of time-frequency domain resources allocated by the network for sensing measurement, thereby realizing the network's implementation of sensing quality control in order to improve the quality of sensing services.
