Figure 1AAs shown, the communication network 100A may include terminal equipment 110, terminal equipment 120, control node 130, access and mobility management function (AMF) 140 and sensing function (SF) 150.

[0022] It should be understood that Figure 1A The number of devices is given for illustrative purposes and does not constitute any limitation on this disclosure. The communication network 100A may include any suitable number of devices suitable for implementing embodiments of this disclosure.

[0023] In some implementations, the terminal device 110 may include at least one of a sensing module and a communication module. For example, such as Figure 1A As shown, the terminal device 110 includes a sensing module 110-1 and a communication module 110-2.

[0024] In some implementations, the sensing module 110-1 in the terminal device 110 may include at least one of the Uu sensing module 110-11 or the sidelink sensing module 110-12.

[0025] In some implementations, Uu sensing modules 110-11 may be configured to perform Uu sensing functions based on network assistance or control, and the Uu sensing functions may include at least one of downlink sensing functions and uplink sensing functions. Sidelink sensing modules 110-12 may be configured to perform sidelink sensing functions.

[0026] Similarly, in some embodiments, the terminal device 120 may include at least one of a sensing module and a communication module. For example, as Figure 1A As shown, the terminal device 120 includes a sensing module 120-1 and a communication module 120-2.

[0027] In some implementations, the control node 130 may include at least one of a sensing module and a communication module. For example, as... Figure 1A As shown, the control node 130 includes a sensing module 130-1 and a communication module 130-2.

[0028] In some implementations, control node 130 may be implemented as a network device (such as a gNB in ​​NR). In such implementations, control node 130 may be referred to as network device 130.

[0029] Alternatively, in some embodiments, control node 130 may be implemented as a roadside unit (RSU). In such embodiments, control node 130 may be referred to as RSU 130.

[0030] Alternatively, in some embodiments, the control node 130 may be implemented as a sense transmit / receive point (TRP). In such embodiments, the control node 130 may be referred to as TRP 130.

[0031] Alternatively, in some embodiments, terminal device 120 may be implemented as a sensing TRP. In such embodiments, terminal device 120 may be referred to as TRP 120.

[0032] In some implementations, AMF 140 may be a node in the core network. AMF 140 may provide matching information about control node 130 or terminal device 110 based on sensing requirements.

[0033] The communications in communication network 100A may conform to any suitable standard, including but not limited to Global System for Mobile Communication (GSM), LTE, LTE-Evolution, LTE-Advanced (LTE-A), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access (CDMA), GSM EDGE Radio Access Network (GERAN), Machine Type Communication (MTC), etc. Furthermore, these communications may be performed according to any generation of communication protocols currently known or to be developed in the future. Examples of communication protocols include, but are not limited to, first-generation (1G), second-generation (2G), 2.5G, 2.75G, third-generation (3G), fourth-generation (4G), 4.5G, fifth-generation (5G), and sixth-generation (6G) communication protocols.

[0034] In some implementations, communication in communication network 100A may include ISAC. Communication networks employing ISAC can share hardware architecture, channel characteristics, and signal processing, and integrate various types of sensing information (such as sensing data from the environment and radar-based sensing information) as well as communication information to achieve higher resource efficiency and provide a smarter, more integrated network solution. ISAC networks can be applied in a wider range of scenarios, including smart homes, smart manufacturing, and environmental monitoring.

[0035] In some implementations, control node 130 may include at least one of the following: The first interface between control node 130 and terminal device 110 The second interface between control node 130 and AMF 140, or The third interface between control node 130 and SF 150.

[0036] In some implementations, terminal device 110 may include at least one of the following: The first interface between control node 130 and terminal device 110 The fourth interface between terminal device 110 and AMF 140, or The fifth interface between terminal device 110 and terminal device 120.

[0037] In implementations where control node 130 is a gNB, the first interface between control node 130 and terminal device 110 can be a Uu interface. In some implementations, sidelink sensing information can be exchanged between control node 130 and terminal device 110 on the Uu interface.

[0038] In some implementations, the Uu sensing process can be performed between the control node 130 and the terminal device 110, and Uu sensing function related information can be exchanged, for example, between the sensing module 130-1 of the control node 130 and the sensing module 110-1 of the terminal device 110.

[0039] In some implementations, the fifth interface between terminal device 110 and terminal device 120 may be a unified air interface, such as a PC5 interface. In such implementations, a sidelink sensing process may be performed between terminal device 110 and terminal device 120, and sidelink sensing function-related information may be exchanged on the PC5 interface (i.e., between sensing module 110-1 of terminal device 110 and sensing module 120-1 of terminal device 120).

[0040] In the example communication network 100A, there is no interface between SF 150 and control node 130. Therefore, SF 150 exchanges information indirectly with control node 130 through AMF 140.

[0041] In the example communication network 100A, terminal device 110 includes a fourth interface between terminal device 110 and AMF 140. AMF 140 can send sensing-related information about terminal device 110 to terminal device 110 via the fourth interface.

[0042] Figure 1B A schematic diagram of another example communication network 100B that can implement embodiments of the present disclosure is illustrated. Example communication network 100B is similar to example communication network 100A. The difference between example communication network 100B and example communication network 100A is that, in example communication network 100B, control node 130 includes a third interface between control node 130 and SF 150. SF 150 can exchange sensing-related information with sensing module 130-1 in control node 130 via the third interface.

[0043] In addition, in the example communication network 100B, terminal device 110 does not include a fourth interface between terminal device 110 and AMF 140. Terminal device 110 can exchange information with AMF 140 through control node 130.

[0044] Figure 1C A schematic diagram of another example communication network 100C that can implement embodiments of the present disclosure is illustrated. Example communication network 100C is similar to example communication networks 100A and 100B. The difference between example communication network 100C and example communication networks 100A and 100B is that example communication network 100C does not include terminal devices 110 and AMF 140 as in example communication networks 100A and 100B.

[0045] In some implementation schemes, Figure 1C The control node 130 can be implemented as a sensor transmit / receive point (TRP). In such embodiments, the control node 130 may be referred to as TRP 130. TRP 130 can communicate with terminal device 120 via a PC5 interface between TRP 130 and terminal device 120. TRP 130 can perform sensing processes with terminal device 120 via the PC5 interface between TRP 130 and terminal device 120.

[0046] For ISAC networks, resources for sensing and communication should be determined. If TDD bands are used for ISAC networks, the TDD allocation scheme for communication resources should be considered as the baseline scheme for resource allocation for sensing and communication.

[0047] Figure 2A , Figure 2B and Figure 2C Examples of TDD allocation schemes for communication resources according to some embodiments of this disclosure are illustrated. Figure 2A , Figure 2B and Figure 2C In the example, communication resources include downlink (DL) resources, flexible (F) resources, and uplink (UL) resources. Resource allocation for communication resources is determined based on TDD configuration.

[0048] exist Figure 2A and Figure 2B In the example, the TDD configuration can be public to the UE. Therefore, the TDD configuration can be accessed via " tdd-UL-DL-ConfigurationCommon "The information element (IE) is used to send it."

[0049] Specifically, in Figure 2A In the example, tdd-UL-DL-ConfigurationCommon IE may include at least one of the following: Subcarrier Spacing (SCS); A pattern; For this mode, configure at least one of the following: The period can be equal to 0.5 ms, 0.625 ms, 1 ms, 1.25 ms, 2 ms, 2.5 ms, 5 ms or 10 ms; The number of DL time slots in this cycle is represented by N_d; The number of DL symbols in this period is represented by n_d; The number of UL time slots in this cycle is represented by N_u; The number of UL symbols in this period, represented by n_u; or The F slot / symbol is located between the DL symbol and the UL symbol.

[0050] exist Figure 2B In the example, tdd-UL-DL-ConfigurationCommon IE may include at least one of the following: SCS; Two modes, each with periods P1 and P2, are respectively. For the first mode, configure at least one of the following: The period (P1) can be equal to 0.5 ms, 0.625 ms, 1 ms, 1.25 ms, 2 ms, 2.5 ms, 5 ms or 10 ms; The number of DL time slots in period P1 is represented by N1_d; The number of DL symbols in period P1 is represented by n1_d; The number of UL time slots in period P1 is represented by N1_u; The number of UL symbols in period P1 is represented by n1_u; or The F slot / symbol is located between the DL symbol and the UL symbol.

[0051] For the second mode, configure at least one of the following: The period (P2) can be equal to 0.5 ms, 0.625 ms, 1 ms, 1.25 ms, 2 ms, 2.5 ms, 5 ms or 10 ms; The number of DL time slots in period P2 is represented by N2_d; The number of DL symbols in period P2 is represented by n2_d; The number of UL time slots in period P2 is represented by N2_u; The number of UL symbols in period P2 is represented by n2_u; or The F slot / symbol is located between the DL symbol and the UL symbol.

[0052] exist Figure 2B In the example, for both modes, the sum of the first cycle P1 and the second cycle P2 should be divided by 20 ms.

[0053] exist Figure 2C In the example, the TDD configuration can be a UE-specific configuration and is used to reconfigure according to... tdd- UL- DL- ConfigurationCommon The F symbol is determined by IE. Specifically, in Figure 2C In the example, tdd- UL- DL- ConfigurationDedicated IE may include at least one of the following: The time slot index within the period, for example, time slot #k; The number of DL symbols in a time slot (e.g., time slot #k) is represented by k_d; or The number of UL symbols in a time slot (e.g., time slot #k) is represented by k_u.

[0054] As described above, a scheme for allocating sensing resources within the sensing resource set needs to be defined.

[0055] In view of this, embodiments of the present disclosure provide a solution for ISAC. In this solution, a first device determines a first resource pattern for sensing a set of sensing resources. The first device determines at least one sensing resource within the set of sensing resources based on the first resource pattern. The first device transmits or receives sensing signals on the at least one sensing resource. This solution provides a scheme for allocating sensing resources within a set of sensing resources.

[0056] In the following text, reference will be made to Figures 3 to 9 The principles of this disclosure are described.

[0057] Figure 3 Signaling diagrams illustrating example procedures 300 for ISAC according to some embodiments of this disclosure are shown. For discussion purposes, reference will be made to... Figure 1A or Figure 1B Process 300 is described. Process 300 may involve... Figure 1A or Figure 1B The terminal equipment 110, network equipment 130, and SF 150 are included.

[0058] In process 300, the sensing service is managed by SF 150, and the configuration used for sensing is determined by SF 150.

[0059] like Figure 3 As shown, SF 150 sends 310 configuration for sensing to network device 130.

[0060] In some implementations, the configuration for sensing may indicate sensing service-related information, requirements, capabilities, etc. For example, the configuration for sensing may include at least one of the following: resource allocation for sensing services, sensing signal-related information, sensing measurement-related information, or sensing result-related information.

[0061] Network device 130 receives the configuration for sensing from SF 150 and forwards it 320 to the terminal device (such as terminal device 110).

[0062] When sensing services are needed, SF 150 sends a 330 sensing request to network device 130. Subsequently, network device 130 further assigns terminal device 110 to perform the sensing process by sending a 340 sensing request to terminal device 110.

[0063] Figure 4 Signaling diagrams illustrating example procedures 400 for ISAC according to some embodiments of this disclosure are shown. For discussion purposes, reference will be made to... Figure 1A or Figure 1B Process 400 is described. Process 400 may involve Figure 1A or Figure 1B The terminal equipment 110, network equipment 130, and SF 150 are included.

[0064] In process 400, the sensing service is managed by SF 150, while the configuration for sensing is determined by network device 130.

[0065] Accordingly, network device 130 sends 410 configuration for sensing to terminal devices (such as terminal device 110).

[0066] When sensing services are needed, SF 150 sends a 420 sensing request to network device 130. Subsequently, network device 130 further assigns terminal device 110 to perform the sensing process by sending a 430 sensing request to terminal device 110.

[0067] Sensing service-related information and configuration can be provided through processes 300 and 400.

[0068] Figure 5 A flowchart illustrating example method 500 according to some embodiments of the present disclosure is shown. In some embodiments, method 500 may be implemented in a first device such as... Figure 1A or Figure 1B This is implemented at terminal device 110, terminal device 120, network device 130, or SF 150.

[0069] At box 510, the first device determines a first resource mode for sensing a set of sensing resources.

[0070] At box 520, the first device determines at least one sensing resource within the sensing resource set based on a first resource pattern used for sensing.

[0071] At box 530, the first device transmits or receives sensing signals on the at least one sensing resource.

[0072] Method 500 provides a scheme for allocating sensing resources within a sensing resource set.

[0073] In some implementations, the sensing resource set may include at least one of the following: a resource set for transmitting or receiving sensing signals, a resource set for reporting sensing results, or a resource set for transmitting or receiving control information related to sensing.

[0074] In some implementations, the sensing resources in the sensing resource set are different from the communication resources. In other words, no communication signals are transmitted on the sensing resources in the sensing resource set.

[0075] In some implementations, the sensing resource set may include a dedicated sensing resource set. Therefore, in an ISAC system, different resource sets can be used for sensing and communication. This provides greater flexibility for sensing services and reduces the impact on the communication system.

[0076] Alternatively, in some implementations, the sensing resource set may include a shared resource set used for both communication and sensing.

[0077] In some implementations, the sensing resource set may include at least one of the following: a set of time-domain resources or a set of frequency-domain resources.

[0078] In some implementations, the sensing resource set may include resources of at least one of the following: Carrier used for sensing services Cells used for this sensing service The bandwidth portion (BWP) used for this sensing service, or The resource pool used for this sensing service.

[0079] In some implementations, the sensing resource set may include at least one of the following: The first resource set for Uu sensing services The second resource set for sidelink (i.e., PC5) sensing services Third resource set for downlink sensing services The fourth resource set used for uplink sensing services The fifth resource set used for sensing transmit-receive points (TRPs), A sixth resource set for the first sensing resource allocation scheme, wherein network device 130 schedules resources in the sixth resource set, or A seventh resource set for the second sensing resource allocation scheme, wherein resources in the seventh resource set are selected and used by at least one terminal device.

[0080] In some implementations, the sensing resource set can be configured or pre-configured by network nodes. For example, the sensing resource set can be configured or pre-configured by SF 150, network device 130, or AMF 140. Alternatively, the sensing resource set can also be predefined in the ISAC system.

[0081] In some implementations, the first resource mode used for sensing can indicate the allocation of sensing resources within the sensing resource set.

[0082] In some implementations, the sensing resources within the sensing resource set are orthogonal to each other. Utilizing orthogonal sensing resources in the sensing resource set can avoid sensing resource conflicts and facilitate sensing resource indication.

[0083] In some implementations, the first resource mode for sensing may indicate that each of the at least one sensing resource includes at least one of the following: The first number of first-type resource units (RU). The second number of resource units in the time domain, The third number of resource units in the frequency domain, The fourth number of resource elements (REs), or The fifth number of resource blocks (RBs).

[0084] In the following text, the first quantity, the second quantity, and the third quantity are represented by Nr, Nt, and Nf, respectively.

[0085] In the following text, for the sake of brevity, the resource unit of the first type is also referred to as RU, the resource unit in the time domain is also referred to as TU, and the resource unit in the frequency domain is also referred to as FU.

[0086] In some implementations, the number of RUs, TUs, FUs, REs, and RBs included in a sensing resource is equal to the size of the sensing resource.

[0087] In some embodiments, the first resource mode for sensing may indicate that each of at least one sensing resource includes a first number of resource units (RUs) of a first type. In such embodiments, the first resource mode for sensing is also referred to as an RU-based sensing resource mode. In such embodiments, each resource unit of the first type, i.e., one RU, may include one resource unit in the delay domain and one resource unit in the Doppler domain, and the RU is a basic resource unit in the delay-Doppler domain. Such embodiments provide a scheme for the allocation of sensing resources in the delay and Doppler domains. In both the delay and Doppler domains, an easy-to-use sensing signal format can be provided, and more accurate measurement results can be obtained.

[0088] In some implementations, resource units within the latency domain may indicate latency resolution. Hereinafter, latency resolution is defined by... express.

[0089] In some implementations, the resource unit in the delay domain may include one of the following: a sixth number of microseconds (μs) or a seventh number of milliseconds (ms).

[0090] In some implementations, the delay resolution may be determined based on at least one of the following: the length of the orthogonal frequency division multiplexing (OFDM) symbol; Ts; Tc; the operating frequency band of the communication system, sensing system, or communication and sensing system; or the maximum delay in the communication system, sensing system, or communication and sensing system.

[0095] In some implementations, the Doppler resolution may be determined based on at least one of the following: the subcarrier spacing (SCS) used for sensing; the operating frequency band of the communication system; the sensing system or a communication and sensing system; the maximum Doppler in the communication system, sensing system, or communication and sensing system; or the maximum speed in the communication system, sensing system, or communication and sensing system. In such implementations, the maximum speed may be an absolute speed or a relative speed.

[0096] In some implementations, the first number of resource units of the first type may include one resource unit in the delay domain and a maximum number of resource units in the Doppler domain. This will refer to Figure 6A Describe it.

Figure 6A In the example, each sensing resource includes a resource unit in the delay domain (i.e., The maximum number of resource units in the Doppler domain is equal to a first number (i.e., Nr). For example, the sensing resource may have an index #t. In such implementations, Nr may represent the size of the sensing resource, where Nr >= 1.

[0098] In some implementations, the first number of resource units of the first type may include the maximum number of resource units in the delay domain and one resource unit in the Doppler domain. This will be referenced. Figure 6B Describe it.

[0099] Figure 6B Examples of RU-based sensing resource patterns according to some embodiments of this disclosure are illustrated. Figure 6B In the example, each sensing resource includes the maximum number of resource units in the delay domain and one resource unit in the Doppler domain (i.e., The maximum number of resource units in the delay domain is equal to the first number (i.e., Nr). For example, a sensing resource may have an index #. In such implementations, Nr may represent the size of the sensing resource, where Nr >= 1.

[0100] In some implementations, the first number of resource units of the first type may include a first plurality of resource units in the delay domain and a second plurality of resource units in the Doppler domain.

[0101] In some implementations, the first plurality of resource units in the delay domain are continuous or discrete, and the second plurality of resource units in the Doppler domain are continuous or discrete. This will be referred to... Figure 6C Describe it.

[0102] Figure 6C Examples of RU-based sensing resource patterns according to some embodiments of this disclosure are illustrated. Figure 6C In the example, each sensing resource includes four continuous resource units in the delay domain and three discrete resource units in the Doppler domain.

[0103] In some implementations, the first number of resource units of the first type may include a twelfth number of resource unit blocks (RUBs), and each RUB may include a thirteenth number of resource units in the delay domain and a fourteenth number of resource units in the Doppler domain. In such implementations, the first resource mode for sensing is also referred to as a RUB-based sensing resource mode.

[0104] In the following text, the twelfth, thirteenth, and fourteenth quantities are represented by Nru, Nde, and Ndp, respectively.

[0105] In some implementations, each of the thirteenth (i.e., Nde) or fourteenth (i.e., Ndp) quantities can be determined based on at least one of the following: configuration, pre-configuration, or pre-definition.

[0106] In some implementations, each of the first quantity (Nr), the twelfth quantity (i.e., Nru), the thirteenth quantity (i.e., Nde), or the fourteenth quantity (i.e., Ndp) can be determined based on at least one of the following: The number of subcarriers in a communication system; a sensing system or a communication and sensing system; The number of symbols in a frame or subframe; Bandwidth of a communication system, a sensing system, or a communication and sensing system; The size of the Fast Fourier Transform (FFT) of the communication system, sensing system, or a combination of communication and sensing systems; SCS used for sensing; The length of the symbol; The maximum latency in a communication system, sensing system, or a combination of communication and sensing systems; Maximum Doppler in communication systems, sensing systems, or communication and sensing systems; or The maximum speed in a communication system, sensing system, or a communication and sensing system.

[0107] Figure 6D Examples of RUB-based sensing resource patterns according to some embodiments of this disclosure are illustrated. Figure 6D In the example, the RUB comprises four resource units in the delay domain (i.e., Nde = 4) and five resource units in the Doppler domain (i.e., Ndp = 5). Each sensing resource comprises four RUBs (i.e., Nru = 4). The RUBs included in the sensing resources are discrete in both the delay and Doppler domains. In such implementations, Nru may represent the size of the sensing resource, where Nru >= 1.

[0108] In some implementations, the first resource mode for sensing may indicate that each of at least one sensing resource includes a second number of TUs (i.e., Nt TUs). In such implementations, the first resource mode for sensing is also referred to as a TU-based sensing resource mode. In such implementations, each TU may include one of the following: µs, ms, symbol, time slot, Ts, or Tc.

[0109] In some implementations, resource patterns used for sensing can be defined within a period. The period for the resource patterns used for sensing (also referred to as the pattern period for brevity) can be configured, pre-configured, or pre-defined.

[0110] In some implementations, the time unit of the mode period can be one of the following: seconds, ms, µs, frames, subframes, time slots, or symbols.

[0111] In some implementations, each sensing resource may include Nt TUs and all available frequency resources in the sensing resource set. That is, time division multiplexing (TDM) is applied among the sensing resources in the sensing resource set, and the same frequency domain resources are maintained for each sensing resource. Because all frequency domain resources are included in each sensing resource, the TU-based sensing resource mode enables sensing services to have higher measurement accuracy and performance. In addition, the TU-based sensing resource mode requires limited resource indication overhead.

[0112] In such implementations, Nt may represent the size of the sensing resource, where Nt >= 1. One or more values ​​of Nt may be configured, preconfigured, or predefined for TU-based sensing resource patterns.

[0113] Figure 7AExamples of TU-based sensing resource patterns according to some embodiments of this disclosure are illustrated. Figure 7A In the example, a single sensing resource pattern is defined for the sensing resource set.

[0114] The sensing resource set includes sensing resources of sensing BWPs with 100 RBs in the frequency domain. These sensing resources have the same size, and this size is pre-configured by the SF 150.

[0115] Each of these sensing resources contains Nt TUs and all frequency resources in the sensing BWP. The sensing BWP is configured with an extended cyclic prefix (ECP). That is, each time slot includes 12 symbols. A TU is one OFDM symbol, and the mode period is equal to one time slot. Each of these sensing resources contains four TUs (i.e., Nt = 4), and the sensing resources in each time slot are assigned indices #0 to #2.

[0116] The positioning reference signal (PRS) is used as the sensing signal. Each PRS used for sensing is transmitted over 4 symbols.

[0117] In some implementations, a first resource mode may indicate that each of at least one sensing resource includes a second number of resource units in the time domain. The second number is configured, pre-configured, or predefined with at least one value for the first resource mode. In other words, the first resource mode may indicate that at least one sensing resource includes at least a first sensing resource in the time domain and a second sensing resource in the time domain. The first sensing resource includes a fifteenth number of TUs, and the second sensing resource includes a sixteenth number of TUs. The fifteenth number is different from the sixteenth number. This will be referred to... Figure 7B Describe it.

[0118] Figure 7B Another example of a TU-based sensing resource pattern according to some embodiments of this disclosure is illustrated. Figure 7B In the example, a single sensing resource pattern is defined for the set of sensing resources. The first resource pattern indicates that each sensing resource in at least one sensing resource includes a second number of TUs. The second number (i.e., Nt) is configured, pre-configured, or predefined with two values ​​for the first resource pattern.

[0119] The sensing resource set includes sensing resources of a sensing BWP with 100 RBs in the frequency domain.

[0120] The mode period is 10 ms. Within the mode period, TU = 100 μs, each of the sensing resources #0 to #9 includes 5 TUs (i.e., Nt = 5), and each of the sensing resources #10 to #14 includes 10 TUs (i.e., Nt = 10).

[0121] Signals based on preambles are used as sensing signals. For example, a pre-configured sequence is transmitted over sensing resources.

[0122] In some implementations, at least one resource mode for sensing is configured or pre-configured for a set of sensing resources. In such implementations, the first device may determine one of the at least one resource mode as the first resource mode.

[0123] Figure 7C Another example of a TU-based sensing resource pattern according to some embodiments of this disclosure is illustrated. Figure 7C In the example, multiple sensing resource patterns are defined for the sensing resource set.

[0124] The sensing resource set includes sensing resources with sensing carriers having a frequency resource of 100 MHz. The mode period is equal to 160 ms. TU = m μs.

[0125] For each set of sensing resources, TU-based sensing resource patterns #1, #2, and #3 are defined. For TU-based sensing resource pattern #1, each sensing resource comprises 2 TUs (i.e., Nt = 2). For TU-based sensing resource pattern #2, each sensing resource comprises 4 TUs (i.e., Nt = 4). For TU-based sensing resource pattern #3, each sensing resource comprises 8 TUs (i.e., Nt = 8).

[0126] Figure 7D Another example of a TU-based sensing resource pattern according to some embodiments of this disclosure is illustrated. Figure 7D In the example, a single sensing resource pattern is defined for the sensing resource set.

[0127] The sensing resource set comprises sensing resources in a pool that have certain time-domain and frequency-domain resources. The time-domain resources included in the sensing resource set are logically continuous, meaning they are not continuous in the physical time domain. TU-based sensing resource patterns are allocated within the sensing resource set. In other words, the pattern period is based on the logically continuous resources in the sensing resource set. The pattern period is equal to 10 ms.

[0128] TU is an OFDM symbol. Each of these sensing resources consists of 4 TUs (i.e., Nt = 4).

[0129] In some implementations, the first resource mode for sensing may indicate that each of at least one sensing resource includes a third number of FUs (i.e., Nf FUs). In such implementations, the first resource mode for sensing is also referred to as an FU-based sensing resource mode. In such implementations, each FU may include one of the following: Hz, kHz, SCS for sensing, subcarrier, RB, BWP, or carrier.

[0130] In some implementations, each sensing resource may include Nf function units (FUs) and Nt transfer units (TUs) in a sensing resource set. That is, frequency division multiplexing (FDM) is applied among the sensing resources in the sensing resource set. FU-based sensing resource patterns require limited resource indication overhead. In such implementations, Nf may represent the size of the sensing resource, where Nf >= 1. One or more values ​​of Nf may be configured, preconfigured, or predefined for FU-based sensing resource patterns. Values ​​of Nt may also be configured, preconfigured, or predefined for FU-based sensing resource patterns. That is, the same value of Nt can be used for all sensing resources in an FU-based sensing resource pattern.

[0131] In some implementations, in the FU-based sensing resource mode, the sensing resource can be a broadband sensing resource that includes all available frequency domain resources in the sensing resource set. That is, Nf is equal to the maximum value of the FUs included in the sensing resource set.

[0132] Alternatively, in some implementations, in the FU-based sensing resource mode, the sensing resource can be a narrowband sensing resource comprising a portion of the available frequency domain resources in the sensing resource set. That is, Nf is less than the maximum value of the FUs contained in the sensing resource set. Nf can be predefined, configured, or pre-configured. In such implementations, each sensing resource comprises Nf consecutive FUs.

[0133] In some implementations, the FU-based sensing resource pattern may include a comb-based sensing resource pattern. In such implementations, each sensing resource comprises Nf discrete resource units in the frequency domain. In other words, each sensing resource uses a comb-based discrete FU.

[0134] In some implementations, the comb-based sensing resource pattern can be allocated across all available frequency resources in the sensing resource set, or within a given frequency range in the sensing resource set.

[0135] Figure 8A Examples of FU-based sensing resource patterns according to some embodiments of this disclosure are illustrated. Figure 8A In the example, multiple sensing resource patterns are defined for the sensing resource set.

[0136] The sensing resource set includes sensing resources for sensing carriers with a frequency resource of 100 MHz. Nt = one symbol, and Nt is predefined in the ISAC system. FU = 20 MHz. FU-based sensing resource patterns #1 and #2 are defined for the sensing resource set. For FU-based sensing resource pattern #1, the sensing resources include 5 FUs (i.e., Nf = 5). That is, the sensing resources in FU-based sensing resource pattern #1 are broadband sensing resources.

[0137] For FU-based sensing resource mode #2, each sensing resource in the sensing resource includes one FU (i.e., Nf = 1). That is, each sensing resource in FU-based sensing resource mode #2 is a narrowband sensing resource. The sensing resources in FU-based sensing resource mode #2 have the same size.

[0138] Figure 8B Another example of a FU-based sensing resource pattern according to some embodiments of this disclosure is illustrated. Figure 8B In the example, a single sensing resource pattern is defined for the sensing resource set.

[0139] The sensing resource set includes sensing resources of a sensing BWP with 100 RBs in the frequency domain. Nt = one symbol, and FU = 1 RB.

[0140] exist Figure 8B In the example, a first resource mode may indicate that each of at least one sensing resource includes a third number of resource elements in the frequency domain. This third number is configured, pre-configured, or predefined with at least one value for the first resource mode. In other words, the resource mode indicates that at least one sensing resource includes at least a third sensing resource and a fourth sensing resource in the frequency domain. The third sensing resource includes a seventeenth number of FUs, and the second sensing resource includes an eighteenth number of FUs. The seventeenth number is different from the eighteenth number. In other words, the sizes of the sensing resources are different.

[0141] For example, the seventeenth quantity equals 10, and the eighteenth quantity equals 50. Each sensing resource in sensing resources #0 to #4 includes 10 TUs, and sensing resource #5 includes 50 TUs. Each sensing resource in sensing resources #0 to #5 includes consecutive RBs and is a narrowband sensing resource.

[0142] Figure 8C Examples of comb-based sensing resource patterns according to some embodiments of this disclosure are illustrated. Figure 8C In the example, the sensing resource set includes sensing resources for sensing carriers with a frequency resource of 100 MHz.

[0143] The comb-based sensing resource pattern is allocated across all available frequency resources in the sensing resource set. Nt = 1 ms, and Nt is pre-configured. FU = 1 MHz. Comb factor = 4. That is, each sensing resource includes one FU for every four consecutive FUs. Each sensing resource includes 25 discrete FUs within a 100 MHz band in the sensing resource set.

[0144] In some implementations, the first resource mode for sensing may indicate that each of at least one sensing resource includes a fourth number of REs. Each RE includes a symbol in the time domain and a subcarrier in the frequency domain. In such implementations, the first resource mode for sensing is also referred to as an RE-based sensing resource mode.

[0145] In some implementations, the first resource mode for sensing may indicate that each of at least one sensing resource includes a fifth number of RBs. In such implementations, the first resource mode for sensing is also referred to as an RB-based sensing resource mode.

[0146] In some implementations, RE-based or RB-based sensing resource modes can reuse traditional RS resource allocation schemes in NR systems. For example, RS may include at least one of the following: PRS, sounding reference signal (SRS), or channel state information-reference signal (CSI-RS). RE-based or RB-based sensing resource modes are more compatible with traditional NR systems.

[0147] Consider an example of a RE-based sensing resource pattern. In this example, the PRS is used as the sensing RS, and the PRS resource allocation scheme is reused as the allocation scheme for the sensing resource pattern. A set of symbols and frequency resources are assigned as dedicated sensing resources. The IE for the allocation of the sensing resource pattern can be provided as follows: NR-SenRS-AssistanceDataPerFreq nr-SenRS-FrequencyLayer NR-SenRS-ResourceSet ::= SEQUENCE { nr-SenRS-ResourceSetID nr-SenRS-Periodicity-and-ResourceSetSlotOffset nr--SenRS-ResourceRepetitionFactor nr-SenRS-ResourceTimeGap nr-SenRS-NumSymbols nr-SenRS-ResourcePower nr-SenRS-ResourceList in: NR-SenRS-AssistanceDataPerFreq indicates the auxiliary data used for sensing RS within the frequency layer. nr-SenRS-FrequencyLayer indicates the configuration of the frequency layer used for sensing. nr-SenRS-ResourceSetID indicates the identifier of the resource set used for sensing. nr-SenRS-Periodicity-and-ResourceSetSlotOffset indicates the period in the time slot used to sense the RS and the time slot offset relative to SFN / DFN #0 time slot #0. nr--SenRS-ResourceRepetitionFactor indicates the number of times the resource used to sense RS is repeated. nr-SenRS-ResourceTimeGap indicates the time gap in the time slot between two repeating resources used to sense RS. nr-SenRS-NumSymbols indicates the number of symbols included in each resource of the resources used to sense RS. nr-SenRS-ResourcePower indicates the transmit power of the sensing RS. nr-SenRS-ResourceList indicates a list of resources used for sensing RS.

[0148] The following sections will describe some implementation schemes for sensing resource indication based on resource patterns used for sensing.

[0149] In some implementations, the first device may determine the first resource mode based on at least one of the following: configuration, pre-configuration, or pre-definition. For example, the first resource mode may be configured or pre-configured via higher-layer signaling.

[0150] In some implementations, the first device may determine the index of each of the at least one sensing resources based on a first resource pattern. In such implementations, the allocation of the at least one sensing resource may indicate the index of each of the at least one sensing resources in the first resource pattern. For example, as referenced... Figure 6A , Figure 6B , Figure 7A , Figure 7B , Figure 7D , Figure 8B , Figure 8C As described, if a single resource pattern for sensing is defined for a set of sensing resources, then the sensing resources can be identified by an index of that sensing resource. Such implementations require less indication overhead.

[0151] In some implementations, the allocation of at least one sensing resource may also be associated with an index of a second device that transmits sensing signals on at least one sensing resource. The index of the second device can be used to generate the sensing signals. The first device may determine at least one sensing resource based on a first resource pattern and the index of the second device. For example, the second device may include one of the following: Figure 1A or Figure 1B Network device 130, Figure 1C TRP 130 in the middle, Figure 1A or Figure 1B Terminal devices 110 or 120.

[0152] In some implementations, the first device may determine a first index of the first resource pattern based on the first resource pattern, and determine a second index of each of the at least one sensing resource. For example, as referenced Figure 7C and Figure 8A As described, if multiple resource patterns for sensing are defined for a set of sensing resources, then the sensing resources can be identified by the index of a first resource pattern and the index of the sensing resources in the first resource pattern.

[0153] In some implementations, the first device may receive a first configuration of a set of sensing resources and a second configuration of a first resource mode.

[0154] In some implementations, the second configuration of the first resource mode may indicate at least one of the following: An index for the first resource pattern of the sensed resource set. The cycle of the first resource model, The temporal offset between the start of the first resource mode and the boundary of the sensed resource set. The type of resource unit in the sensing resource set. The size of the sensing resources within the sensing resource set. The configured authorization identifier, The period of transmitting the sensing signal, At least one index of at least one sensed resource in the first resource mode, or The transmission power parameter for transmitting the sensing signal.

[0155] Consider a first example of an indication of sensing resources based on a resource pattern used for sensing. In this first example, the resources of a dedicated BWP (i.e., a sensing BWP) are configured as a sensing resource set, and a resource pattern for sensing the sensing resource set is assigned via higher-layer signals from network device 130 as follows: Sensing-BWP-Config Sensing-pattern-Config sensing-pattern-Id sensing-pattern { SenPattern-Periodicity SenPattern-Offset SenPattern-ResourceUnit SenPattern-NumUnit } in: “Sensing-BWP-Config” indicates the frequency domain configuration used for sensing BWP; "sensing-pattern-Id" indicates the identifier (ID, identity) of the resource pattern used to sense the resource set. “SenPattern-Periodicity” indicates the period of the resource pattern used for sensing; "SenPattern-Offset" indicates the temporal offset between the start of the resource pattern used for sensing and the boundary of the resource set; "SenPattern-ResourceUnit" indicates the type of resource unit of the sensed resource, such as TU, FU, or RU; “SenPattern-NumUnit” indicates the size of the sensing resource, such as Nt, Nf, or Nr.

[0156] In the first example, network device 130 schedules sensing resources for terminal device 110 and instructs terminal device 110 via a DCI having an index of the sensing BWP, an ID of the resource mode, and an index of the sensing resource in the resource mode. Terminal device 110 should then send sensing signals on the assigned sensing resources.

[0157] Consider a second example of an indication of sensing resources based on a resource pattern used for sensing. In this second example, resources on a dedicated carrier are configured for sensing, and the network device should schedule sensing resources for the terminal device via cross-carrier indication. The secondary cell (Scell) used for sensing and the associated sensing resource pattern on the carrier are configured by the network device via a system information block (SIB). For example, the SIB may include: Sensing-FreqConfigCommon Sensing-pattern-Config in: "Sensing-FreqConfigCommon" indicates the frequency domain configuration of the carrier used for sensing services; "Sensing-pattern-Config" indicates the configuration of the resource pattern used for sensing (such as a second configuration of the first resource pattern).

[0158] For TRP A and TRP B, network devices semi-statically assign sensing resources via higher-layer signaling: Sen-ConfiguredGrantConfig Sen-ConfigIndex Sen-Period Sen-Pattern-Id Sen-Resource-Id Sen-ResourcePower in: "Sen-ConfiguredGrantConfig" indicates the configured authorization used for sensing; "Sen-ConfigIndex" indicates the identifier of the configured authorization; “Sen-Period” indicates the period during which the sensing signal of the TRP is transmitted; “Sen-Pattern-Id” indicates the ID of the resource pattern used for sensing on the sensing carrier; "Sen-Resource-Id" indicates the ID of the sensed resource in the sensed resource pattern; "Sen-ResourcePower" indicates the transmit power parameter for transmitting the sense signal.

[0159] According to the assignment from the network device, TRP A and TRP B shall periodically send sensing signals on the resources, and at least one terminal device shall obtain the indexes of TRP A and TRP B and the relevant sensing resource allocation for each of TRP A and TRP B, and then detect the sensing signals from TRP A and TRP B.

[0160] The following sections will describe some implementations of sensing resource indications in the absence of resource patterns for sensing.

[0161] In some implementations, the allocation of sensing resources can be based on at least one of the following to indicate the starting location and size of the sensing resources: TU, FU, RE, RB, or RU. For example, a resource indication value (RIV) can be used as an indicator of the sensing resources. Such implementations can provide a more flexible sensing resource indication scheme.

[0162] In some implementations, the starting position of the sensing resource can be an indicator of the starting position of the sensing resource. For example, the starting position of the sensing resource can be an index of TU or FU.

[0163] In some implementations, the resource size of the sensing resource may indicate the number of resource units contained within the sensing resource. For example, the resource size of the sensing resource may indicate the number of TUs or FUs.

[0164] Consider an example of an indication of sensing resources in the absence of a resource mode for sensing. In this example, within a shared carrier used for both communication and sensing, network device 130 assigns semi-static sensing resources (in the absence of a resource mode for sensing) via a SIB for its sensing signal transmission. For example, the SIB may include: DLSensing-Config dlSensingresource-Id dlSensingresource-Periodicity dlSensingresource-slotOffset dlSensingresource-symbol dlSensingresource-startRB dlSensingresource-numRB in: “dlSensingresource-Id” indicates the ID of the sensing resource used by the network device 130 to send sensing signals; “dlSensingresource-Periodicity” indicates the period of time during which the sensing resource is used; “dlSensingresource-slotOffset” indicates the temporal offset between the starting time slot and the boundary of the system frame; The “dlSensingresource-symbol” indicates the symbol allocation used for sensing in the indicated time slot; “dlSensingresource-startRB” indicates the index of the starting RB used for sensing within the shared carrier; “dlSensingresource-numRB” indicates the number of RBs used for sensing from the starting RB.

[0165] Then, according to the SIB, the terminal devices (such as terminal devices 110 and 120) can periodically detect the sensing signals from network device 130 on the assigned resources.

[0166] Figure 9 This is a simplified block diagram of a device 900 suitable for implementing embodiments of the present disclosure. Device 900 can be considered as follows: Figure 1A , Figure 1B or Figure 1C Another example implementation of the terminal device 110, terminal device 120, control node 130, or SF 150 shown. Therefore, device 900 can be implemented as terminal device 110, terminal device 120, control node 130, or SF 150, or as at least a portion of these devices.

[0167] As shown in the figure, device 900 includes a processor 910, a memory 920 coupled to the processor 910, a suitable transceiver 940 coupled to the processor 910, and a communication interface coupled to the transceiver 940. The memory 910 stores at least a portion of a program 930. Depending on the requirements, the transceiver 940 can be used for bidirectional or unidirectional communication. The transceiver 940 may include at least one of a transmitter 942 and a receiver 944. The transmitter 942 and receiver 944 may be functional modules or physical entities. The transceiver 940 has at least one antenna to facilitate communication; however, in practice, the access node mentioned in this application may have several antennas. The communication interface can represent any interface necessary for communication with other network elements, such as the X2 / Xn interface for bidirectional communication between eNBs / gNBs, the S1 / NG interface for communication between the Mobility Management Entity (MME) / Access and Mobility Management Function (AMF) / SGW / UPF and eNBs / gNBs, the Un interface for communication between eNBs / gNBs and relay nodes (RNs), or the Uu interface for communication between eNBs / gNBs and terminal equipment.

[0168] In summary, the implementation schemes disclosed herein can provide the following solutions.

[0169] In a first aspect, a first device is provided. The first device includes a processor. The processor is configured to cause the first device to: determine a first resource pattern for sensing a set of sensing resources; determine at least one sensing resource within the set of sensing resources based on the first resource pattern; and transmit or receive a sensing signal on the at least one sensing resource.

[0170] In some implementations, the first resource mode indicates the allocation of sensing resources within the sensing resource set.
