Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a resource configuration method, apparatus, device, chip, storage medium, and program product. Background Art

[0002] The perception process refers to the process in which a sensing device continuously performs perception operations (such as sending and receiving perception signals) within a specified time period to obtain perception data, and then sends the perception data to the Sensing Function (SF) for processing to obtain the perception results. Perception working modes in related technologies include independent perception and collaborative perception. In the collaborative perception working mode, for the terminal, due to the large difference between the uplink communication signal strength and the perceived signal reflected signal strength power, when in medium and long-range detection, the communication signal strength will be much greater than the perceived signal strength, thus making it impossible to effectively collect the perception signal with a smaller strength.

[0032] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] It should be noted that in the embodiments of the present application, the term "and / or" is merely a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the embodiments of the present application, the character " / " generally indicates that the associated objects are in an "or" relationship.

[0034] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0035] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0036] An integrated communication and perception system refers to a system that has both communication and perception capabilities through integrated design (spectrum resource sharing, integrated air interface, integrated hardware architecture, etc.), multi-point collaboration, and intelligent information interaction. Its working modes are divided into two categories: independent perception and collaborative perception.

[0037] Independent perception: Figure 1 The figure shows the process of independent sensing mode. Node A transmits a synaesthesia signal and receives the target's reflected signal, obtaining characteristic parameters of the surrounding environment and implementing sensing functions such as target detection, positioning, identification, and tracking. The advantage is that it can complete the process of sensing non-networked targets without the assistance of other networked nodes. The main challenges are the low energy of the echo signal and the presence of self-interference.

[0038] Collaborative Perception: Figure 2The figure shows a schematic diagram of the collaborative sensing process. Node A transmits a synaesthesia signal, and collaborative node B receives the reflected signal from the target. After information exchange and fusion processing between one or more nodes, the environmental characteristic parameters between the transmitting and receiving nodes are obtained. The advantages of this method are the elimination of self-interference between transmission and reception, and the ability to achieve collaborative reception processing gain through multi-node collaboration. The main challenge lies in inter-node synchronization.

[0039] The network elements involved in the 5G network system include: User Equipment (UE), Radio Access Network (RAN), User Plane Function (UPF), Access and Mobility Management Function (AMF), Location Management Function (LMF), Session Management Function (SMF), Policy Control Function (PCF), Application Function (AF), Network Exposure Function (NEF), Unified Data Management (UDM), Network Data Analytics Function (NWDAF), etc.

[0040] The technical solutions of the embodiments of the present application can be applied to, but are not limited to, a 5G network system architecture. For example, they can also be applied to an enhanced 5G network system architecture, a 6G network system architecture, or a future network system architecture.

[0041] Taking the 5G network system architecture as an example, the Sensing Function (SF) can be introduced into the 5G core network. The basic functions of SF include: sensing authorization, sensing control, sensing data processing, and sensing result output.

[0042] refer to Figure 3 , Figure 3The core network structure diagram provided for the embodiment of the present application is as follows: the standard perception scheme in the 3rd Generation Partnership Project (3GPP) is: the service request end (such as AF) sends a perception request to the SF, the SF authorizes or controls the perception device (such as UE and / or RAN) to perform the perception operation, the perception device sends the perception data obtained by performing the perception operation to the SF, the SF processes the perception data to obtain the perception result, and opens the perception result. The deployment form of SF can be an independent deployment or a joint deployment with a 5GC network element (such as AMF or LMF, etc.). In addition, according to the deployment requirements, SF can exist in two forms: SF-C (control plane) and SF-U (user plane). Among them, when the UE is used as a perception device, the transmission path of the perception data can be UE→RAN→UPF→SF-U or UE→RAN→SF-U. When the base station is used as a perception device, the transmission path of the perception data can be RAN→UPF→SF-U or RAN→SF-U.

[0043] A sensing device is a device that performs sensing tasks (or sensing operations). Sensing tasks can be performed by the UE, by the base station, or by the UE and the base station in collaboration. For example, the UE sends a sensing signal and receives a sensing signal formed by the target object reflecting the sensing signal. For example, the base station sends a sensing signal and receives a sensing signal formed by the target object reflecting the sensing signal. For example, the UE sends a sensing signal and the base station receives a sensing signal formed by the target object reflecting the sensing signal. For example, the base station sends a sensing signal and the UE receives a sensing signal formed by the target object reflecting the sensing signal. After receiving the sensing signal, the sensing device processes the sensing signal to generate sensing data, and sends the sensing data to the SF. The SF processes the sensing data to obtain a sensing result.

[0044] Relying on the large-scale deployment of communication networks to build a collaborative synaesthesia network has the advantages of collaborative reception and fusion processing gain, no need for self-interference cancellation, low overhead without long CP, no need for hardware modification, low-cost and fast technology implementation. However, in actual networking, the collaborative perception mode of base station A sending and B receiving requires changing the uplink and downlink configuration of the transmitting and receiving base stations, breaking the traditional uplink and downlink configuration method. Figure 4 The figure shows the collaborative sensing process in which base station A transmits and B receives signals. While receiving the sensing signal reflection, node B also needs to receive the uplink signal from its service user. That is, in addition to receiving the reflected signal sent by node A that reaches node B via the target, node B also receives uplink communication signals from communication users 1-3 within its coverage area.

[0045] In related technologies, when building a collaborative sensing network, the communication signal strength is significantly greater than the reflected signal strength of the sensing signal for terminals. During medium- and long-range detection, if the difference between the communication signal strength and the reflected signal strength is too large, the limited bit count of the receiver ADC will exceed the available dynamic range of the hardware ADC, drowning out the weaker sensing signal and preventing effective sensing signal acquisition.

[0046] Based on the above technical problems, the present application embodiment proposes a resource configuration method. Figure 5 A flow chart of a resource configuration method applied to a first network device provided in an embodiment of the present application is shown as follows: Figure 5 As shown, the method may include the following steps:

[0047] Step 501: Send first indication information to a terminal device.

[0048] Among them, the first indication information is used to indicate at least one perception resource in the first perception resource set, and the at least one perception resource is used to instruct the terminal device to perform uplink transmission adjustment on the target resource, and the uplink transmission adjustment includes no uplink transmission and / or uplink power adjustment.

[0049] In an embodiment of the present application, the first network device first sends first configuration information to the terminal device, and the first configuration information is used to configure a first perception resource set. Then, the first network device sends first indication information to the terminal device, and the first indication information is used to indicate at least one perception resource in the first perception resource set, wherein the at least one perception resource is used to instruct the terminal device to perform uplink transmission adjustment on the target resource, where the uplink transmission adjustment includes no uplink transmission and / or uplink power adjustment, and the target resource here refers to a resource that requires uplink transmission adjustment in uplink communication.

[0050] Here, the first indication information includes a first bitmap, where bits in the first bitmap correspond to sensing resources in the first sensing resource set, and the value of the bit indicates whether the sensing resource corresponding to the bit belongs to at least one sensing resource. For example, if the bit value is 1, it indicates that the sensing resource corresponding to the bit belongs to at least one sensing resource, and if the bit value is 0, it indicates that the sensing resource corresponding to the bit does not belong to at least one sensing resource.

[0051] Here, the first sensing resource set includes M sensing resources, where M is a positive integer; the first configuration information includes sensing resource pattern information of the M sensing resources. The sensing resource pattern information includes at least one of the following:

[0052] First information, used to indicate the starting PRB of the sensing resource;

[0053] The second information is used to indicate the number of PRBs of the sensing resource;

[0054] The third information is used to indicate the PRB index of the sensing resource;

[0055] The fourth information is used to indicate the starting symbol of the sensing resource;

[0056] The fifth information is used to indicate the number of symbols of the sensing resource;

[0057] The sixth information is used to indicate the symbol index of the perception resource;

[0058] The seventh information is used to indicate the starting time slot and time slot period of the sensing resource;

[0059] The eighth information is used to indicate the time domain comb structure of the sensing resource;

[0060] The ninth information is used to indicate the frequency domain comb structure of the perception resource.

[0061] Among them, the starting PRB represents the first physical resource block allocated to the perception resource, the number of PRBs represents the total number of physical resource blocks allocated to the perception resource, the PRB index represents the position of the physical resource block allocated to the perception resource in the frequency domain, the starting symbol represents the first symbol allocated to the perception resource, the number of symbols represents the total number of symbols allocated to the perception resource, and the symbol index represents the position of the symbol allocated to the perception resource in the time domain.

[0062] As an implementation method, the PRBs where the perception resources are located can be determined by the starting PRB of the perception resources and the number of PRBs of the perception resources; as another implementation method, the PRBs where the perception resources are located can be determined by the PRB index of the perception resources.

[0063] As one implementation method, the symbols where the perception resource is located can be determined by the starting symbol of the perception resource and the number of symbols of the perception resource; as another implementation method, the symbols where the perception resource is located can be determined by the symbol index of the perception resource.

[0064] The starting time slot indicates the first time slot where the sensing resource is located within a time slot cycle. The time slots where the sensing resource is located can be determined by the starting time slot and the time slot cycle of the sensing resource.

[0065] It should be noted that one time slot includes multiple symbols. Exemplarily, one time slot includes 14 symbols.

[0066] The time-domain comb structure can be represented by the parameter Nt,comb. The value of Nt,comb indicates that one symbol out of multiple symbols in the time domain belongs to a sensing resource. For example, Nt,comb = 1 means that every symbol in the time domain belongs to a sensing resource. Nt,comb = 2 means that one out of every two symbols in the time domain belongs to a sensing resource.

[0067] The frequency domain comb structure can be represented by the parameter Nf,comb. The value of Nf,comb indicates that one of the multiple PRBs in the frequency domain is a sensing resource. For example, Nf,comb = 3 means that one of every three PRBs in the frequency domain is a sensing resource. Nf,comb = 4 means that one of every four PRBs in the frequency domain is a sensing resource.

[0068] In some implementations, the first network device may further send second indication information to the terminal device to indicate that the target resource is the intersection or union of at least one perception resource.

[0069] In some embodiments, the first network device may also obtain second configuration information from the second network device or the perception server for configuring a second perception resource set, wherein the second perception resource set is used for the second network device to send a perception signal, and the first perception resource set is a subset of the second perception resource set or the first perception resource set is the same as the second perception resource set.

[0070] Here, the second sensing resource set includes N sensing resources, where N is a positive integer, and the second configuration information includes sensing resource pattern information of the N sensing resources. The sensing resource pattern information includes at least one of the following:

[0071] First information, used to indicate the starting PRB of the sensing resource;

[0072] The second information is used to indicate the number of PRBs of the sensing resource;

[0073] The third information is used to indicate the PRB index of the sensing resource;

[0074] The fourth information is used to indicate the starting symbol of the sensing resource;

[0075] The fifth information is used to indicate the number of symbols of the sensing resource;

[0076] The sixth information is used to indicate the symbol index of the perception resource;

[0077] The seventh information is used to indicate the starting time slot and time slot period of the sensing resource;

[0078] The eighth information is used to indicate the time domain comb structure of the sensing resource;

[0079] The ninth information is used to indicate the frequency domain comb structure of the perception resource.

[0080] In the technical solution of the embodiment of the present application, the first network device sends a first indication message to the terminal device, and the first indication message is used to indicate at least one perception resource in the first perception resource set, and the at least one perception resource is used to instruct the terminal device to perform an uplink transmission adjustment without uplink transmission and / or uplink power adjustment on the target resource. In this way, by instructing the terminal device to perform an uplink transmission adjustment on the target resource, it is possible to avoid the problem that the reflected signal of the perception signal conflicts with the uplink communication signal, resulting in the failure of the perception task.

[0081] The embodiment of the present application also proposes a resource configuration method. Figure 6 A schematic diagram of a process for configuring resources for a terminal device according to an embodiment of the present application is provided. Figure 6 As shown, the method may include the following steps:

[0082] Step 601: Receive first indication information sent by a first network device.

[0083] The first indication information is used to indicate at least one perception resource in the first perception resource set, and the at least one perception resource is used to instruct the terminal device to perform uplink transmission adjustment on the target resource, wherein the uplink transmission adjustment includes no uplink transmission and / or uplink power adjustment.

[0084] In an embodiment of the present application, the terminal device first receives first configuration information sent by the first network device, and the first configuration information is used to configure a first perception resource set. Then, the terminal device receives first indication information sent by the first network device, and the first indication information is used to indicate at least one perception resource in the first perception resource set, wherein the at least one perception resource is used to instruct the terminal device to perform uplink transmission adjustment on the target resource, where the uplink transmission adjustment includes no uplink transmission and / or uplink power adjustment, and the target resource here refers to a resource that requires uplink transmission adjustment in uplink communication.

[0085] Here, the first indication information includes a first bitmap, where bits in the first bitmap correspond to sensing resources in the first sensing resource set, and the value of the bit is used to indicate whether the sensing resource corresponding to the bit belongs to at least one sensing resource or does not belong to at least one sensing resource. For example, if the bit value is 1, it means that the sensing resource corresponding to the bit belongs to at least one sensing resource, and if the bit value is 0, it means that the sensing resource corresponding to the bit does not belong to at least one sensing resource.

[0086] Here, the first sensing resource set includes M sensing resources, where M is a positive integer; the first configuration information includes sensing resource pattern information of the M sensing resources. The sensing resource pattern information includes at least one of the following:

[0087] First information, used to indicate the starting PRB of the sensing resource;

[0088] The second information is used to indicate the number of PRBs of the sensing resource;

[0089] The third information is used to indicate the PRB index of the sensing resource;

[0090] The fourth information is used to indicate the starting symbol of the sensing resource;

[0091] The fifth information is used to indicate the number of symbols of the sensing resource;

[0092] The sixth information is used to indicate the symbol index of the perception resource;

[0093] The seventh information is used to indicate the starting time slot and time slot period of the sensing resource;

[0094] The eighth information is used to indicate the time domain comb structure of the sensing resource;

[0095] The ninth information is used to indicate the frequency domain comb structure of the perception resource.

[0096] In some embodiments, the terminal device may also receive the second indication information sent by the first network device, which is used to indicate that the target resource is the intersection or union of at least one perception resource.

[0097] In the technical solution of an embodiment of the present application, a terminal device receives first indication information sent by a first network device, the first indication information is used to indicate at least one perception resource in a first perception resource set, and the at least one perception resource is used to instruct the terminal device to perform uplink transmission adjustment without uplink transmission and / or uplink power adjustment on the target resource. In this way, by instructing the terminal device to perform uplink transmission adjustment on the target resource, it is possible to avoid the problem that the reflected signal of the perception signal conflicts with the uplink communication signal, resulting in the failure of the perception task.

[0098] The present application also proposes an application scenario of a resource configuration method, which is divided into three stages:

[0099] (1) Obtaining perception resource configuration information

[0100] Node B obtains sensing resource configuration information from node A or the sensing server. The configuration information includes but is not limited to at least one sensing resource time-frequency position and a sending period.

[0101] Among them, the time-frequency position of the perception resource includes but is not limited to the time domain starting symbol, number of symbols, symbol index and the frequency domain starting PRB, number of PRBs, PRB index, time domain comb, frequency domain comb, etc.

[0102] For example, the configuration information of a perception resource can be:

[0103] Sensing-Resource::=SEQUENCE{

[0104] startingPRB 2

[0105] nrofPRBs 8

[0106] SymbolIndex 2, 6, 10

[0107] Periodicityandoffset slot 5:2

[0108] Nt,comb=2

[0109] Nf,comb=2

[0110] }

[0111] Among them, startingPRB represents the starting PRB in the frequency domain, and its value is 2; nrofPRBs represents the number of PRBs, and its value is 8; SymbolIndex represents the symbol index, and the symbol index here includes 2, 6, and 10. It can be seen that the symbol index of the starting symbol is 2 and the number of symbols is 3; Periodicityandoffset represents the period and offset, and the starting time slot here is 2 and the time slot period is 5; Nt,comb represents the time domain comb structure, and its value is 2, indicating that one out of every two symbols in the time domain belongs to the perception resource; Nf,comb represents the frequency domain comb structure, and its value is 2, indicating that one out of every two PRBs in the frequency domain belongs to the perception resource.

[0112] (2) Conflicting Resource Judgment

[0113] When Node B is in cooperative sensing reception mode (sensing priority is higher than communication), Node B determines whether the sensing resources reported by Node A conflict with the Physical Uplink Shared Channel (PUSCH) resources scheduled by it.

[0114] The conflict determination method includes but is not limited to the node B receiving the perception signal resource and the user's uplink signal resource at the same time in the same time-frequency resource.

[0115] (3) Resource indication process

[0116] When the perception signal resource received by the Node B conflicts with the PUSCH resource configured by the Node B for its service user, the Node B sends indication information to the user with the resource conflict, indicating the resource set that the user with the resource conflict needs to avoid in the uplink communication, that is, performing uplink transmission adjustment in the uplink communication according to the resource set to be avoided, including but not limited to no uplink transmission (no uplink signal is sent), uplink power adjustment, etc.

[0117] The indication information is UE-specific and is used to avoid conflicts between PUSCH resources and cooperative sensing reception tasks during transmission. The indication process includes semi-static configuration via Radio Resource Control (RRC) signaling and dynamic configuration via Downlink Control Information (DCI) signaling:

[0118] RRC signaling semi-static configuration

[0119] RRC signaling semi-static configuration is used to configure sensing resources, including PRBs, time slots, frequencies, etc. Semi-static configuration means that the configuration information is fixed for a period of time, but when the demand changes, the configuration information may be adjusted to ensure that the resource allocation and scheduling during the communication process can meet the performance requirements of the system.

[0120] Here, the form of RRC signaling semi-static configuration is as follows:

[0121]

[0122]

[0123] Among them, Sensing-Resource-patternGroup represents the mapping pattern set of configured sensing resources, Sensing-Resource-pattern1,…,Sensing-Resource-patternM respectively represent the mapping patterns of different sensing resources in the set, and each mapping pattern of sensing resource corresponds to a different Sensing-Resource-patternID. M is the maximum number of mapping patterns of sensing resources supported by the user.

[0124] DCI signaling dynamic configuration

[0125] After the semi-static configuration of RRC signaling, the Node B generates DCI signaling based on the real-time status and needs of the system. This signaling includes information about downlink data transmission, such as the transmission resources and transmission format, and adds an uplink communication resource conflict avoidance field and an uplink communication resource avoidance type field in the DCI signaling format DCI0_0 and / or DCI0_1 to indicate the perception resources configured in the RRC signaling. The Node B then transmits the generated DCI signaling to the user. The user determines the PUSCH resources that need to be adjusted for uplink transmission based on the indication information in the DCI signaling to ensure that PUSCH data transmission does not conflict with the collaborative perception reception task.

[0126] Specifically, in the existing DCI0_0 and / or DCI0_1, an uplink communication resource conflict avoidance field is added to indicate whether the mapping pattern of the perception resource configured in the RRC signaling belongs to the perception resource corresponding to the PUSCH resource for which the user performs uplink transmission adjustment. The number of bits occupied by the uplink communication resource conflict avoidance field is equal to the number of mapping patterns of the perception resources configured in the mapping pattern set of the perception resources configured in the RRC signaling, that is, the different bits occupied by the field have a corresponding relationship with the mapping patterns of the perception resources configured in the perception resource mapping pattern set configured in the RRC signaling, and the value of the bit is used to indicate whether the resource corresponding to the mapping pattern of the perception resource corresponding to the bit needs to be avoided, that is, whether the PUSCH resource transmitted simultaneously with the resource needs to be adjusted for uplink transmission. For example, if the bit value is 1, it means that the resources corresponding to the mapping pattern of the perception resource corresponding to the bit need to be avoided, that is, the PUSCH resources transmitted simultaneously with the resource need to be adjusted for uplink transmission. If the bit value is 0, it means that the resources corresponding to the mapping pattern of the perception resource corresponding to the bit do not need to be avoided, that is, the PUSCH resources transmitted simultaneously with the resource do not need to be adjusted for uplink transmission.

[0127] Specifically, in the existing DCI0_0 and / or DCI0_1, an uplink communication resource avoidance type field is added. This field only occupies 1 bit, and the value of this bit is used to indicate that the resources that need to be avoided are the intersection or union of the mapping patterns of one or more perception resources. For example, if the bit value is 1, it means that the resources that need to be avoided are the intersection of the mapping patterns of one or more perception resources. If the bit value is 0, it means that the resources that need to be avoided are the union of the mapping patterns of one or more perception resources. If no indication is given, the bit value of this field defaults to 0, that is, the resources that need to be avoided are the union of the mapping patterns of one or more perception resources jointly configured by RRC and DCI, so as to reserve the maximum resources to prevent conflicts.

[0128] It should be noted that when Node B is in non-cooperative sensing reception mode, the above-mentioned RRC configuration and DCI configuration are invalid, the uplink communication resource conflict avoidance field is 000, the uplink communication resource avoidance type field is 0 or 1, or DCI0_0 and / or DCI0_1 do not include the uplink communication resource conflict avoidance field and the uplink communication resource avoidance type field.

[0129] For example, the semi-static configuration of RRC signaling can be:

[0132] Among them, the mapping pattern set of the sensing resources configured in the RRC signaling includes Sensing-Resource-pattern1, Sensing-Resource-pattern2 and Sensing-Resource-pattern3, and Sensing-Resource-pattern1, Sensing-Resource-pattern2 and Sensing-Resource-pattern3 are respectively configured with corresponding sensing resources, such as Figure 7a The following is a schematic diagram of the sensing resource configuration of Sensing-Resource-pattern1 in the mapping pattern set of the configured sensing resources, as shown in Figure 7b The following is a schematic diagram of the sensing resource configuration of Sensing-Resource-pattern2 in the mapping pattern set of the configured sensing resources, as shown in Figure 7c The figure shows a sensing resource configuration diagram of Sensing-Resource-pattern3 in the mapping pattern set of the configured sensing resources.

[0133] If the uplink communication resource avoidance field is 110 in DCI0_0 and DCI0_1, it means that the resources corresponding to Sensing-Resource-pattern1 and Sensing-Resource-pattern2 need to be avoided, that is, the PUSCH resources transmitted simultaneously with the resource need to be adjusted for uplink transmission. The uplink communication resource avoidance type field is 1, which means that the intersection of Sensing-Resource-pattern1 and Sensing-Resource-pattern2 is taken, that is, the result of the intersection of Sensing-Resource-pattern1 and Sensing-Resource-pattern2 is the sensing resource that needs to be avoided, such as Figure 8 The figure shows the result of the intersection of Sensing-Resource-pattern1 and Sensing-Resource-pattern2.

[0134] If the uplink communication resource avoidance field is 110 in DCI0_0 and DCI0_1, it means that the resources corresponding to Sensing-Resource-pattern1 and Sensing-Resource-pattern2 need to be avoided, that is, the PUSCH resources transmitted simultaneously with the resources need to be adjusted for uplink transmission. If the uplink communication resource avoidance type field is 0, it means that Sensing-Resource-pattern1 and Sensing-Resource-pattern2 are taken as the union, that is, the result of taking the union of Sensing-Resource-pattern1 and Sensing-Resource-pattern2 is the sensing resource that needs to be avoided, such as Figure 9 The figure shows the result of union of Sensing-Resource-pattern1 and Sensing-Resource-pattern2.

[0135] In the technical solution of the embodiment of the present application, when uplink data transmission conflicts with the collaborative perception reception task, a mapping pattern set of perception resources is semi-statically configured through RRC signaling, and a field is added to the format DCI0_0 and / or DCI0_1 of the DCI signaling to indicate the perception resources configured in the RRC signaling, so that the user can determine the PUSCH resources that need to be adjusted for uplink transmission according to the indication information in the DCI signaling, and dynamically adjust the resource allocation of uplink data transmission to ensure that PUSCH data transmission does not conflict with the collaborative perception reception task, so that the perception task is received successfully, and improve the system performance and resource utilization.
