[0109] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0110] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0111] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0112] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0113] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0114] To support multiplexing and resource reservation of PDCCH (Physical Downlink Control Channel) or PDSCH, the standard supports RB (Resource Block) level bitmaps in the frequency domain and symbol-level bitmaps in the time domain. It also allows configuration of a slot-level bitmap to indicate which slot has a rate matching pattern configured. Resources configured with a rate matching pattern can be indicated by the terminal via a rate matching indicator in the DCI (Downlink Control Information) to determine whether the resources in the rate matching pattern are available for scheduled PDSCH transmission. In addition to RB-symbol level rate matching, the standard also includes RE (Resource Element) level rate matching, which uses ZP CSI-RS (Zero Power CSI-RS) as rate matching resources, primarily for resource avoidance with LTE (Long Term Evolution) reference signals.

[0115] In summary, regardless of whether it's RB-symbol level or RE level rate matching resources, after configuration, these resources are generally no longer used for PDSCH information transmission, and the UE (User Equipment) behavior is in an idle state, meaning it neither performs any measurements nor receives any signals. From the perspective of resource reservation, future rate matching technologies related to PUSCH (Physical Uplink Shared Channel) may also be defined.

[0116] In existing communication systems, apart from Sidelink, which enables terminal-side detection of sensing results to obtain information on other users' resource usage, other resource allocations are primarily used for communication functions. However, sensing functions can be implemented not only at the terminal side but also at the base station side. Therefore, implementing sensing functions in existing communication systems requires configuring specific available sensing resources. Sensing resources refer to resources used to receive or transmit sensing signals or environmental information sent by target objects. The sensing function mainly refers to the act of collecting information on target attributes and status; the obtained information can be used to assist communication access or management, improving service quality and communication efficiency.

[0117] Towards next-generation communication networks, the communication spectrum is evolving towards higher frequency bands such as millimeter waves and terahertz, leading to increasing overlap between the communication spectrum and the traditional sensing spectrum. This makes integrated design between the two possible. Integrated sensing and communication refers to the fusion of communication and sensing functions, enabling future communication systems to simultaneously perform both communication and sensing capabilities. While transmitting information, these systems can also detect, track, identify, and image targets or environments, as well as acquire information such as location, distance, and speed. Integrated sensing and communication also facilitates the joint scheduling of communication and sensing resources.

[0118] In order to make full use of existing resources to realize sensing functions, such as Figure 1 As shown, an embodiment of the present invention provides a resource configuration method applied to a terminal, comprising:

[0119] Step 101: Receive resource configuration information sent by the network device; wherein the resource configuration information includes: a rate matching pattern index and first information, the rate matching pattern index is used to indicate rate matching resources, the first information is used to indicate the relationship between the rate matching pattern index and the target sensing resource, and the target sensing resource is used to implement sensing functions.

[0120] In this step, the first information can be used to indicate which rate matching resources can be reused as sensing resources (i.e., as target sensing resources), and further indicate the rate matching resources for receiving or sending sensing information, thereby realizing the sensing function.

[0121] Among them, the sensing function means that the terminal sends sensing signals or receives sensing signals sent by other terminals. For example, it can obtain information such as the status of the surrounding environment or the resource usage of other terminals through signal acquisition and processing.

[0122] Step 102: Determine the target sensing resource based on the resource configuration information.

[0123] In this embodiment, rate matching resources can be configured as sensing resources by means of signaling indication (e.g., receiving resource configuration information sent by network devices). In this way, the terminal can determine the rate matching resources that can be reused as sensing resources through the received resource configuration information, and then use them to realize the sensing function.

[0124] It should be noted that, by reusing existing rate matching resources as sensing resources, this embodiment of the invention can achieve sensing on rate matching resources without changing the basic configuration of existing rate matching, thereby making full use of existing resources and improving resource utilization. Here, reuse can also be understood as redefinition, that is, on known resources, through signaling instructions, the behavior of the UE (i.e., the terminal) on rate matching is regulated to achieve the effect of completing the sensing function on rate matching resources that do not transmit data.

[0125] Optionally, the first information includes: bitmap information and / or rate matching sensing state parameters corresponding to the rate matching pattern index.

[0126] It should be noted that each terminal can be configured with multiple rate matching patterns. Network devices can configure whether to reuse rate matching resources as sensing resources through higher-layer signaling (e.g., through rate matching sensing status parameters), or they can use a bitmap to indicate which rate matching resource to reuse as a sensing resource. The bitmap information can be a pattern-level bitmap, and the number of bits in the pattern-level bitmap is less than or equal to the maximum number of configurable rate matching patterns.

[0127] Optionally, determining the target sensing resource based on the resource configuration information includes at least one of the following:

[0128] (i) Determine the target sensing resource based on the rate matching pattern index and the bitmap information.

[0129] In an optional embodiment of the present invention, the network device can use a Bitmap to indicate whether a resource configured with a Ratematching pattern can be reused as a sensing resource. Specifically, when configuring a Ratematching pattern through higher-layer signaling, the network device can define a pattern-level Bitmap to indicate whether the Rate matching resource corresponding to rateMatchPatternId can be reused as a sensing resource.

[0130] like Figure 2As shown, each individual square represents an OFDM (Orthogonal Frequency Division Multiplexing) symbol in the time domain and a subcarrier in the frequency domain. In this optional embodiment, the UE configures four rate matching patterns, where squares filled with different patterns represent different patterns. Assuming the Bitmap value used to indicate whether rate matching resources are reused is Bitmap=0101, it means that the UE reuses the resources configured with rate matching pattern 1 and the resources configured with rate matching pattern 3 as sensing resources to complete the sensing function, while the UE performs rate matching on the resources configured with rate matching pattern 2 and the resources configured with rate matching pattern 4.

[0131] (ii) When the parameter value of the rate matching sensing state parameter is a preset parameter value, the rate matching resource indicated by the rate matching pattern index is determined as the target sensing resource.

[0132] It should be noted that each rate matching pattern index (i.e., rateMatchPatternId) corresponds to a specific value of a rate matching pattern. rateMatchPatternId is used to indicate the rate matching resource corresponding to the physical channel.

[0133] In another optional embodiment of the present invention, when configuring the rate matching pattern via higher-layer signaling, the higher-layer signaling configuration can be used to indicate which rate matching resource can be reused as a sensing resource. Specifically, when configuring the rate matching pattern, a higher-layer parameter (e.g., a rate matching sensing status parameter) can be used to indicate whether the rate matching resource corresponding to rateMatchPatternId can be reused as a sensing resource.

[0134] The rate matching sensing status parameter (rateMatchSensingStatus) can be an enumerated parameter, for example, its value can be {on, off}. A partial configuration code example is shown below:

[0135] RateMatchPattern::=SEQUENCE{

[0136] rateMatchPatternId RateMatchPatternId,

[0137] rateMatchSensingStatus ENUMERATED{ON,OFF},OPTIONAL

[0138] …

[0139] }

[0140] In this way, the UE can determine the corresponding behavior on the rate matching resource corresponding to rateMatchPatternId by judging the value of the received rateMatchSensingStatus. For example, when the value of rateMatchSensingStatus is on, it means that the UE is sensing on the rate matching resource; when the value of rateMatchSensingStatus is off, it means that the UE is performing rate matching (i.e., rateMatch) on the rate matching resource.

[0141] Optionally, the method further includes:

[0142] Receive downlink control information (DCI) sent by network devices;

[0143] The step of determining the target sensing resource based on the resource configuration information includes:

[0144] The target sensing resource is determined based on the DCI and the resource configuration information.

[0145] In this embodiment, after the network device configures or indicates a certain Ratematching resource (e.g., a resource configured with Rate matching pattern_1) for the purpose of implementing the sensing function through higher-layer signaling or through a Bitmap, the network device can further indicate through the DCI rate matching indicator that this reserved resource configured with Rate matching pattern_1 can be multiplexed for the PDSCH transmission scheduled by this DCI. That is, the Rate matching resource is configured (indicated) for data transmission. In this case, the resource configured with Rate matching pattern_1 can only be used for the PDSCH transmission scheduled by the DCI.

[0146] In other words, if a network device instructs communication data transmission to occur on a certain Rate matching resource, then communication data transmission will occur on that Rate matching resource, and this Rate matching resource cannot be reused as a sensing resource. That is, the priority of communication data transmission is higher than the priority of sensing signal transmission. When a conflict arises between the configuration of reusing a Rate matching resource as a sensing resource via resource configuration information and the DCI indication used for scheduling data transmission, the terminal follows the DCI indication. This ensures that sensing resources can be configured in the communication system to achieve on-demand sensing functionality without interfering with or preempting normal communication resources.

[0147] Optionally, determining the target sensing resource based on the DCI and the resource configuration information includes: determining a first resource for Physical Downlink Shared Channel (PDSCH) transmission based on the rate matching indicator in the DCI; and determining the target sensing resource based on the first resource and the resource configuration information.

[0148] In this embodiment, the network device can determine which Ratematching resource is used for PDSCH transmission based on the rate matching indicator in the DCI, and then determine the Ratematching resource that can be reused as a sensing resource.

[0149] like Figure 3 As shown, in an optional embodiment of the present invention, when configuring the rate matching pattern through higher-layer signaling, a Bitmap (e.g., Bitmap = 0101) is used to instruct the UE to perform the sensing function on resources configured with rate matching pattern 1 and resources configured with rate matching pattern 3, and the UE to perform rate matching on resources configured with rate matching pattern 2 and resources configured with rate matching pattern 4. If the network device instructs the resource configured with rate matching pattern 1 to be used for PDSCH transmission in this DCI scheduling via DCI, then the resource configured with rate matching pattern 1 cannot be reused as a sensing resource. In this case, rate matching is performed on resources configured with rate matching pattern 1, resources configured with rate matching pattern 2, and resources configured with rate matching pattern 4, and the resource configured with rate matching pattern 3 can be reused as a sensing resource.

[0150] Optionally, determining the target sensing resource based on the first resource and the resource configuration information includes: determining the first sensing resource based on the rate matching pattern index and the bitmap information; and determining the rate matching resource in the first sensing resource that is different from the first resource as the target sensing resource.

[0151] In this embodiment, candidate sensing resources (i.e., first sensing resources) can be initially determined by indicative rate matching pattern index and bitmap information of the rate matching resources. Furthermore, target sensing resources that can be used for sensing can be selected from the first sensing resources. The target sensing resources cannot be the first resources used for physical downlink shared channel (PDSCH) transmission.

[0152] Optionally, determining the target sensing resource based on the first resource and the resource configuration information includes: when the parameter value of the rate matching sensing state parameter is a preset parameter value, determining the rate matching resource indicated by the rate matching pattern index as the second sensing resource; and determining the rate matching resource in the second sensing resource that is different from the first resource as the target sensing resource.

[0153] In this embodiment, candidate sensing resources (i.e., second sensing resources) can be initially determined by indicating the rate matching pattern index of the rate matching resource and the parameter value of the rate matching sensing state parameter. Furthermore, target sensing resources that can be used for sensing can be selected from the second sensing resources. The target sensing resources cannot be the first resources used for physical downlink shared channel (PDSCH) transmission.

[0154] The resource configuration method of this embodiment, without changing the basic configuration of the existing rate matching pattern, can determine the rate matching resources that can be reused as sensing resources through resource configuration information, thereby achieving the effect of completing the sensing function on the rate matching resources, making full use of existing resources to realize the sensing function, and improving resource utilization.

[0155] like Figure 4 As shown, an embodiment of the present invention provides a resource configuration method applied to a network device, comprising:

[0156] Step 401: Determine resource configuration information;

[0157] Step 402: Send resource configuration information to the terminal, or perform sensing based on the resource configuration information; wherein, the resource configuration information includes: a rate matching pattern index and first information, the rate matching pattern index is used to indicate rate matching resources, the first information is used to indicate the relationship between the rate matching pattern index and the target sensing resource, and the target sensing resource is used to implement the sensing function.

[0158] In this embodiment, when the network device is performing sensing, its sensing resource configuration does not need to be indicated to the terminals covered by its network. In other words, the network device can receive sensing signals or receive echoes of signals sent by the network device on the Rate matching resource through resource scheduling.

[0159] Optionally, the first information includes: bitmap information and / or rate matching sensing state parameters corresponding to the rate matching pattern index.

[0160] Optionally, the method further includes sending a DCI to the terminal.

[0161] In this way, the terminal can determine the first resource for PDSCH transmission based on the rate matching indicator in the DCI. Therefore, when a conflict arises between the network device's instruction to multiplex the rate matching resource as a sensing resource and the DCI instruction used for scheduling data transmission, the terminal will prioritize the DCI instruction and use the rate matching resource for communication data transmission. This ensures that sensing resources are configured in the communication system to achieve on-demand sensing without interfering with or preempting normal communication resources.

[0162] Optionally, the step of sensing based on the resource configuration information includes: determining the target sensing resource based on the resource configuration information; and receiving a sensing signal on the target sensing resource.

[0163] Here, the sensing signal can be sent by the device that needs to be measured, or by a device in the environment, or it can be an echo signal reflected back by other objects from a signal sent by the network device itself.

[0164] In this embodiment, the network device can determine the resources used for sensing based on resource configuration information, and then receive sensing signals on the resources to realize the sensing function.

[0165] The resource configuration method of this embodiment can indicate to the terminal, through resource configuration information, the rate matching resources that can be reused as sensing resources, or determine the resources used for sensing by network devices, thereby realizing the sensing function of network devices and the effect of the terminal completing the sensing function on rate matching resources. It makes full use of existing resources to realize the sensing function and improves resource utilization.

[0166] like Figure 5 As shown, a resource configuration device according to an embodiment of the present invention is applied to a terminal and includes:

[0167] The receiving module 510 is used to receive resource configuration information sent by the network device; wherein, the resource configuration information includes: a rate matching pattern index and first information, the rate matching pattern index is used to indicate rate matching resources, the first information is used to indicate the relationship between the rate matching pattern index and the target sensing resource, and the target sensing resource is used to implement sensing functions;

[0168] The processing module 520 is used to determine the target sensing resource based on the resource configuration information.

[0169] In this embodiment, rate matching resources can be configured as sensing resources by means of signaling indication (e.g., receiving resource configuration information sent by network devices). In this way, the terminal can determine the rate matching resources that can be reused as sensing resources through the received resource configuration information, and then use them to realize the sensing function.

[0170] Optionally, the first information includes: bitmap information and / or rate matching sensing state parameters corresponding to the rate matching pattern index.
