[0131] For the specific implementation of the embodiment shown in FIG1B , please refer to the subsequent content and will not be described in detail here.

[0132] In a first aspect, embodiments of the present disclosure provide a resource determination method. Figure 2 is a schematic flow chart illustrating a resource determination method according to an embodiment of the present disclosure. The resource determination method illustrated in this embodiment can be performed by a first node, which includes, but is not limited to, an access network device. The first node can communicate with a second node, which includes, but is not limited to, at least one of the following: a terminal or a core network device.

[0133] As shown in FIG2 , the resource determination method may include the following steps:

[0134] In step S201, relevant resources used by a terminal for direct link positioning are determined according to first information received from a second node.

[0135] It should be noted that the embodiment shown in FIG. 2 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0136] According to an embodiment of the present disclosure, a first node receives first information from a second node and then determines, based on the first information, relevant resources for direct link positioning by a terminal. Accordingly, the first node can determine the relevant resources for direct link positioning by the terminal based on external information, namely, the first information from the second node. This helps ensure that the determined relevant resources for direct link positioning by the terminal are well-suited for the terminal, thereby ensuring a positioning effect achieved by the terminal based on the resources with reference to direct link positioning.

[0137] In some embodiments, the related resources for direct link positioning include at least one of the following:

[0138] Ranging and Sidelink Positioning Protocol (RSPP) transmission resources. It should be noted that RSPP can also be called Sidelink Positioning Protocol (SLPP);

[0139] Direct link location resources.

[0140] For example, ranging and direct link positioning protocol transmission resources are used by terminals to transmit positioning and direct link related information (for example, interaction of positioning capabilities, discovery of terminals, selection of terminals, negotiation of positioning methods, negotiation of positioning resources, transmission of positioning measurement results, etc.), and direct link positioning resources are used by terminals to send and / or receive reference signals used for positioning in the direct link positioning process (for example, direct link positioning reference signals).

[0141] In some embodiments, the direct link positioning resource includes at least one of the following:

[0142] Direct link positioning reference signal frequency information, such as bandwidth, frequency, etc.

[0143] Direct link positioning reference signal time information, such as the starting position and duration of the transmission.

[0144] In some embodiments, the first information includes at least one of the following:

[0145] Direct link positioning request information;

[0146] Authorization information of the terminal.

[0147] It should be noted that when the first information includes direct link positioning request information and terminal authorization information, the direct link positioning request information and the terminal authorization information may come from the same node. In this case, the first node may be one node; and when the direct link positioning request information and the terminal authorization information come from different nodes, in this case, the first node may be multiple nodes, for example, the first node includes a terminal and a core network device.

[0148] In some embodiments, the first information is carried in at least one of the following:

[0149] NGAP message, wherein the first node includes an access network device and the second node includes a core network device;

[0150] F1AP message, wherein the first node includes a gNB-DU in a split radio access network architecture, and the second node includes a gNB-CU or a gNB-CU-CP in a split radio access network architecture;

[0151] XnAP message, wherein the first node includes a target base station in a handover process, and the second node includes a source base station in a handover process, or the first node includes a new serving base station, and the second node includes a last serving base station;

[0152] New Air Interface Positioning Protocol A message, wherein the first node includes an access network device and the second node includes a core network device;

[0153] Signaling, wherein the first node includes an access network device and the second node includes the terminal.

[0154] In some embodiments, the first node includes at least one of the following: an access network device (e.g., a base station), a gNB-DU (Distributed Unit) under a wireless access network separation architecture.

[0155] In some embodiments, the second node includes at least one of the following: an access network device (e.g., a base station), a terminal, a core network device, a gNB-CU (Central Unit) under a wireless access network separation architecture, and a gNB-CU-CP (Control Plane) under a wireless access network separation architecture.

[0156] The following describes, through several embodiments, a case where the first information includes direct link positioning request information.

[0157] For example, when the first information includes direct link positioning request information, and the first node includes an access network device, and the second node includes a core network device, such as a location management function (LMF), the second node can send the direct link positioning request information to the first node in a new radio positioning protocol A (NR positioning protocol A, NRPPA) message.

[0158] The NRPPA message may be an NRPPA message related to the terminal, for example, the NRPPA message includes at least one of the following: a positioning information request of the terminal, a direct link positioning configuration request of the terminal.

[0159] For example, when the first information includes direct link positioning request information, and the first node includes an access network device, and the second node includes a terminal, the second node may send the direct link positioning request information to the first node in signaling.

[0160] The signaling includes at least one of the following: RRC (Radio Resource Control) signaling, physical layer signaling (such as downlink control information (DCI)), and media access control layer signaling (such as media access control layer control element (MAC CE)).

[0161] For example, when the first information includes direct link positioning request information, and the first node includes a gNB-DU under a wireless access network separation architecture, and the second node includes a gNB-CU or a gNB-CU-CP under a wireless access network separation architecture, the second node can send the direct link positioning request information to the first node in an F1AP (F1 Application Protocol) message.

[0162] The F1AP message may be an F1AP message related to the terminal, for example, the F1AP message includes at least one of the following: a positioning information request of the terminal, and a direct link positioning configuration request of the terminal.

[0163] For example, when the first information includes direct link positioning request information, and the first node includes an access network device, and the second node includes a core network device, such as an Access and Mobility Management Function (AMF), the second node can send the direct link positioning request information to the first node in an NGAP (Next Generation Application Protocol) message.

[0164] The NGAP message may be an NGAP message related to the terminal, for example, the NGAP message includes at least one of the following: a context establishment request of the terminal, a context modification request of the terminal.

[0165] The following describes, through several embodiments, a case where the first information includes authorization information of the terminal.

[0166] For example, when the first information includes authorization information of the terminal, and the first node includes an access network device, and the second node includes a core network device, such as AMF, the second node can send the authorization information of the terminal to the first node in an NGAP message.

[0167] The NGAP message may be an NGAP message related to the terminal, for example, the NGAP message includes at least one of the following: a context establishment request of the terminal, a context modification request of the terminal.

[0168] For example, when the first information includes authorization information of the terminal, and the first node includes a gNB-DU under a wireless access network separation architecture, and the second node includes a gNB-CU or gNB-CU-CP under a wireless access network separation architecture, the second node can send the direct link positioning request information to the first node in an F1AP (F1 Application Protocol) message, and the second node can send the authorization information of the terminal to the first node in the F1AP message.

[0169] The F1AP message may be an F1AP message related to the terminal, for example, the F1AP message includes at least one of the following: a context establishment request of the terminal, and a context modification request of the terminal.

[0170] For example, the terminal can perform switching. When the first information includes the authorization information of the terminal, the first node can include the target base station corresponding to the target cell to which the terminal needs to switch, and the second node can include the source base station corresponding to the source cell where the terminal was located before the switching. The second node can send the authorization information of the terminal to the first node in the XnAP (Xn Application Protocol) message.

[0171] The XnAP message may be an XnAP message related to the terminal, for example, the XnAP message includes a handover request.

[0172] For example, a terminal (e.g., in an inactive state) can change its service base station. When the first information includes the authorization information of the terminal, the first node can include the changed service base station, which can also be called the new service base station. The second node can include the service base station before the terminal is changed, which can also be called the last service base station. The second node can send the authorization information of the terminal to the first node in an XnAP (Xn Application Protocol) message.

[0173] The XnAP message may be an XnAP message related to the terminal, for example, the XnAP message includes: a context feedback message of the terminal.

[0174] The specific content of the direct link positioning request information is exemplarily described below through several embodiments.

[0175] In some embodiments, the direct link positioning request information includes at least one of the following:

[0176] the role of the terminal;

[0177] an identifier of the terminal;

[0178] Task identifier for direct link positioning;

[0179] Service type for direct link positioning;

[0180] Quality of Service (QoS) for direct link positioning;

[0181] Transmission characteristics of the direct link Positioning Reference Signal (PRS);

[0182] Direct link positioning reference signal transmission stop information;

[0183] The cell information where the direct link positioning terminal is located.

[0184] In some embodiments, the role of a terminal (also referred to as the type of terminal) refers to the role of the terminal in a direct link positioning process or task. For example, the role includes at least one of the following: anchor terminal (anchor UE), target terminal (target UE), location terminal (location UE), server terminal (server UE); for example, the role includes at least one of the following: server terminal only (server UE only) or server terminal or non-direct link positioning terminal, direct link positioning terminal (SL Positioning UE), wherein the direct link positioning terminal includes a terminal participating in direct link positioning, such as an anchor terminal and a target terminal. The first node can determine relevant resources for direct link positioning for the terminal based on the role of the terminal.

[0185] It should be noted that, in the embodiments of the present disclosure, the anchor terminal, the target terminal, and the location terminal may also be referred to as a reference terminal (reference UE).

[0186] In some embodiments, the role of the terminal can be classified according to whether it participates in direct link positioning (i.e., whether it receives and / or sends direct link positioning reference signals). For example, a terminal participating in direct link positioning (e.g., anchor UE, location UE, or target UE) needs to be allocated direct link positioning reference signal resources, while a terminal not participating in direct link positioning (e.g., server UE or client UE) cannot be allocated direct link positioning reference signal resources.

[0187] In some embodiments, the role of the terminal can be classified according to whether it receives or sends a direct link positioning reference signal. For example, a terminal that needs to send a direct link positioning reference signal needs to be allocated corresponding direct link positioning reference signal resources, and a terminal that only receives a direct link positioning reference signal cannot be allocated direct link positioning reference signal resources (e.g., resources used to send a direct link positioning reference signal).

[0188] In some embodiments, the role of the terminal can be classified according to whether it needs to interact through the RSPP protocol. For example, a terminal that needs to interact with the RSPP protocol needs to be allocated corresponding RSPP resources, while a terminal that does not need to interact with the RSPP protocol (for example, a terminal that is only responsible for sending and receiving direct link positioning reference signals and interacts through the network) cannot be allocated RSPP protocol resources.

[0189] In some embodiments, the role of the terminal can be classified according to the reception and / or transmission of the direct link positioning reference signal. For example, the role of the terminal includes at least one of the following: direct link TP (Transmission Point), direct link RP (Reception Point), and direct link TRP (Transmission-Reception Point).

[0190] In some embodiments, the terminal identifier can be used to uniquely identify a specific terminal. For example, the terminal identifier can be an identifier (ID) of a cell where the terminal is located, or a Cell-Radio Network Temporary Identifier (C-RNTI) assigned to the terminal. The first node can determine relevant resources for direct link positioning for the terminal based on the terminal identifier.

[0191] In some embodiments, a direct link positioning task (Transaction) identifier, also known as a service identifier or a transaction identifier, may be used to identify a specific direct link positioning task. The first node may determine relevant resources for direct link positioning for the terminal based on the direct link positioning task identifier.

[0192] In some embodiments, a service type for direct link positioning may be used to indicate a service type used for direct link positioning, where the service type includes at least one of a V2X (vehicle to everything) and a ProSe (Proximity Services) identifier. The first node may determine, for the terminal, relevant resources for direct link positioning based on the service type for direct link positioning.

[0193] In some embodiments, the quality of service of the direct link positioning may be used to indicate the quality of service required for the direct link positioning. The first node may determine, for the terminal, relevant resources for direct link positioning based on the quality of service of the direct link positioning.

[0194] In some embodiments, the quality of service of the direct link positioning includes a range requirement, and the first node may determine relevant resources for direct link positioning for the terminal according to the quality of service of the direct link positioning.

[0195] In some embodiments, direct link positioning reference signal transmission stop information can be used by the first node to determine when to release a specific direct link positioning reference signal resource allocated to the terminal or to determine the time to allocate a specific direct link positioning reference signal resource to the terminal. The first node can determine relevant resources for direct link positioning for the terminal based on the direct link positioning reference signal transmission stop information.

[0196] In some embodiments, the cell information where the direct link positioning terminal is located can also be referred to as the information of the cell where the terminal participating in the direct link positioning is located. The first node can send the relevant resources used by the terminal for direct link positioning to the third node based on the cell information where the direct link positioning terminal is located.

[0197] For example, the first node can determine that the base station corresponding to the cell where the anchor terminal participating in the direct link positioning is located is the first node, and the base station corresponding to the cell where the target terminal participating in the direct link positioning is located is the third node based on the cell information where the direct link positioning terminal is located. Then, after the first node determines the relevant resources used by the anchor terminal for direct link positioning, it can send information about the relevant resources used by the anchor terminal for direct link positioning to the third node, so that when the third node determines the relevant resources used by the target terminal for direct link positioning, it can avoid conflict with the relevant resources used by the anchor terminal for direct link positioning.

[0198] In some embodiments, the transmission characteristic information of the direct link positioning reference signal includes at least one of the following: cell information; bandwidth information; transmission type; transmission information; start time; duration; and end time. The first node may determine, for the terminal, relevant resources for direct link positioning based on the transmission characteristic information of the direct link positioning reference signal to improve resource utilization efficiency and avoid interference.

[0199] In some embodiments, the authorization information of the terminal includes at least one of the following:

[0200] Authorizing role information of the terminal;

[0201] Authorized transmission quality of service information;

[0202] Authorized positioning service quality information.

[0203] In some embodiments, the role information of the authorized terminal can be used to indicate whether the first node terminal is authorized for a specific role. When the terminal is authorized for a specific role, the first node can determine the services, resources, service quality and other related information corresponding to the specific role, and then determine the relevant resources for direct link positioning for the terminal based on these relevant information.

[0204] It should be noted that, in addition to the several roles described in the preceding embodiments, the role information of the authorized terminal may also include other roles. For example, roles permitted to receive and / or transmit specific resources may include at least one of the following: terminals permitted to receive direct link positioning reference signal resources, terminals permitted to transmit direct link positioning reference signal resources, terminals permitted to both receive and transmit direct link positioning reference signal resources, and terminals permitted to use ranging and direct link positioning protocol resources. Distinguishing terminals based on these roles facilitates more reasonable and accurate resource allocation by the first node. For example, for terminals permitted to receive direct link positioning reference signal resources, the first node may allocate direct link positioning reference signal resources for reception; and for terminals permitted to transmit direct link positioning reference signal resources, the first node may allocate direct link positioning reference signal resources for transmission.

[0205] In some embodiments, the authorized transmission quality of service information may be used by the first node to determine direct link positioning protocol transmission resources for the terminal.

[0206] For example, the authorized transmission service quality information may include: a mapping table between direct link positioning services and direct link transmission service quality parameters, and the type of the direct link positioning service may be, for example, V2X or ProSe.

[0207] In some embodiments, the first node may determine the direct link positioning protocol transmission resources based on the authorized transmission service quality information and the direct link positioning service type;

[0208] In some embodiments, the first node may use the authorized transmission quality of service information as the default or default quality of service of the terminal to determine the direct link positioning protocol transmission resources of the terminal in a direct link positioning task.

[0209] In some embodiments, the authorized positioning service quality information may be used by the first node to determine a direct link positioning reference signal resource for the terminal.

[0210] For example, the authorized positioning service quality information may include: a mapping table between direct link positioning services and direct link positioning service quality parameters, and the type of the direct link positioning service may be, for example, V2X or ProSe.

[0211] In some embodiments, the first node may determine the direct link positioning reference signal resource according to the authorized positioning service quality information and the direct link positioning service type;

[0212] In some embodiments, the first node may use the authorized positioning service quality information as the default or default service quality of the terminal to determine the direct link positioning reference signal resources of the terminal in an SL positioning task.

[0213] FIG3 is a schematic flow chart of another resource determination method according to an embodiment of the present disclosure. The method shown in this embodiment can be performed by the first node. As shown in FIG3, the resource determination method further includes at least one of the following:

[0214] In step S301, it is determined to allocate the relevant resources for direct link positioning to the terminal, and configuration information of the relevant resources for direct link positioning is sent to the second node; it is determined not to allocate the relevant resources for direct link positioning to the terminal, and allocation failure information of the relevant resources for direct link positioning is sent to the second node.

[0215] It should be noted that the embodiment shown in FIG. 3 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0216] In some embodiments, the first node determines, based on the first information, relevant resources for direct link positioning of the terminal. This may include, in addition to allocating relevant resources for direct link positioning to the terminal, also determining not to allocate relevant resources for direct link positioning to the terminal. When allocating relevant resources for direct link positioning to the terminal, specific ranging and direct link positioning protocol transmission resources, and / or direct link positioning resources, may be determined based on the first information.

[0217] For example, the first node determines to allocate relevant resources for direct link positioning to the terminal based on the first information, and can send the configuration information of the determined relevant resources for direct link positioning to the second node. The configuration information can serve as a response message to the first information, so that the second node can determine the relevant resources of the terminal for direct link positioning based on the configuration information.

[0218] For example, if the first node determines not to allocate resources related to direct link positioning to the terminal based on the first information, it may send allocation failure information of the resources related to direct link positioning to the second node. The allocation failure information may serve as a response message to the first information, so that the second node can determine, based on the allocation failure information, that allocation of resources related to direct link positioning to the terminal has failed. The failure information may also carry a specific failure reason, such as authorization failure or resource unavailability.

[0219] In some embodiments, the configuration information and / or the allocation failure information is carried in at least one of the following:

[0220] New Air Interface Positioning Protocol A message, wherein the first node includes an access network device and the second node includes a core network device;

[0221] NGAP message, wherein the first node includes an access network device and the second node includes a core network device;

[0222] signaling, wherein the first node includes an access network device and the second node includes the terminal;

[0223] F1AP message, wherein the first node includes a gNB-DU under a wireless access network separation architecture, and the second node includes a gNB-CU or gNB-CU-CP under a wireless access network separation architecture.

[0224] For example, the first node includes an access network device, the second node includes an LMF, and the first node can send configuration information or allocation failure information to the second node in an NRPPA message.

[0225] The NRPPA message may be an NRPPA message related to the terminal. For example, when it is determined that relevant resources for direct link positioning are allocated to the terminal, the NRPPA message includes at least one of the following: a positioning information feedback message and a direct link positioning configuration feedback message; for example, when it is determined that relevant resources for direct link positioning are not allocated to the terminal, the NRPPA message includes at least one of the following: a positioning information request failure message and a direct link positioning configuration failure message.

[0226] For example, the first node includes an access network device, and the second node includes a terminal. The first node may send configuration information or allocation failure information to the second node in signaling. The signaling may be, for example, RRC signaling, DCI, MAC CE, etc.

[0227] For example, the first node includes a gNB-DU under a wireless access network separation architecture, and the second node includes a gNB-CU or gNB-CU-CP under a wireless access network separation architecture. The first node can send configuration information or allocation failure information to the second node in an F1AP message.

[0228] The F1AP message may be an F1AP message related to the terminal. For example, when it is determined that relevant resources for direct link positioning are allocated to the terminal, the F1AP message includes at least one of the following: a positioning information feedback message and a direct link positioning configuration feedback message; for example, when it is determined that relevant resources for direct link positioning are not allocated to the terminal, the F1AP message includes at least one of the following: a positioning information request failure message and a direct link positioning configuration failure message.

[0229] For example, the first node includes an access network device, and the second node includes an AMF. The first node may send configuration information or allocation failure information to the second node in an NGAP message. The NGAP message may be an NGAP message related to the terminal. For example, when determining to allocate relevant resources for direct link positioning to the terminal, the NGAP message includes at least one of the following: a context establishment feedback message for the terminal, or a context modification feedback message for the terminal. For example, when determining not to allocate relevant resources for direct link positioning to the terminal, the NGAP message includes at least one of the following: a context establishment failure message for the terminal, or a context modification failure message for the terminal.

[0230] It should be noted that when the second node is a terminal, the terminal can determine the relevant resources for direct link positioning based on the configuration information, and then participate in the direct link positioning based on the determined relevant resources; when the second node is not a terminal, the second node can, upon receiving the configuration information, provide resource configuration information as needed, or send the configuration information to the terminal for the terminal to determine the relevant resources for direct link positioning, or, upon receiving the allocation failure information, the second node can provide resource allocation failure information as needed, or send the allocation failure information to the terminal for the terminal to determine that the allocation of relevant resources for direct link positioning has failed.

[0231] FIG4 is a schematic flow chart of another resource determination method according to an embodiment of the present disclosure. The method shown in this embodiment can be executed by the first node. As shown in FIG4, the resource determination method further includes:

[0232] In step S401, information on related resources used by the terminal for direct link positioning is sent to a third node.

[0233] It should be noted that the embodiment shown in FIG. 4 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0234] In some embodiments, the first node may send information about resources used by the terminal for direct link positioning (eg, configuration information or allocation failure information) to a third node, where the third node is different from the second node.

[0235] For example, the first node may determine, based on the cell information where the direct link positioning terminal is located, that the base stations corresponding to the cells where the multiple terminals participating in the direct link positioning are located are different.

[0236] For example, the base station corresponding to the cell where the anchor terminal participating in direct link positioning is located is the first node, and the base station corresponding to the cell where the target terminal participating in direct link positioning is located is the third node. Then, after the first node determines the relevant resources used by the anchor terminal for direct link positioning, it can send information about the relevant resources used by the anchor terminal for direct link positioning to the third node.

[0237] For another example, the base station corresponding to the cell where the target terminal participating in direct link positioning is located is the first node, and the base station corresponding to the cell where the anchor terminal participating in direct link positioning is located is the third node. Then, after the first node determines the relevant resources used by the target terminal for direct link positioning, it can send information about the relevant resources used by the target terminal for direct link positioning to the third node.

[0238] When the information about the terminal's related resources for direct link positioning includes configuration information, the third node can avoid conflicts with the anchor terminal's related resources for direct link positioning when determining the target terminal's related resources for direct link positioning according to the configuration information.

[0239] When the information about the terminal's direct link positioning related resources includes allocation failure information, the third node may not consider the anchor terminal's direct link positioning related resources when determining the target terminal's direct link positioning related resources based on the allocation failure information.

[0240] In some embodiments, the first node and the second node are different base stations. The first node may carry information about relevant resources used by the terminal for direct link positioning in an XnAP message and send it to the third node.

[0241] The XnAP message may be a message related to or not related to the terminal. For example, the XnAP message includes at least one of the following: an interface establishment related message, a radio access network (RAN) configuration update related message, and a direct link configuration notification message.

[0242] In some embodiments, sending information about resources related to direct link positioning used by a terminal to a third node includes sending information about resources related to direct link positioning used by the terminal to the third node through a fourth node.

[0243] The first node sends information about the relevant resources used by the terminal for direct link positioning to the third node. The information about the relevant resources used by the terminal for direct link positioning can be sent directly to the third node as in the previous embodiment, or the information about the relevant resources used by the terminal for direct link positioning can be sent to the third node through the fourth node.

[0244] It should be noted that the fourth node and the second node may be the same node or different nodes.

[0245] For example, when the fourth node is an LMF, an NRPPA message can be sent to the third node carrying information about the relevant resources used by the terminal for direct link positioning. The NRPPA message can be a message related to the terminal or a message not related to the terminal, such as a direct link configuration notification message.

[0246] It should be noted that the above embodiments of the first node, the second node, the third node, and the fourth node are merely exemplary descriptions, and the situations of the first node, the second node, the third node, and the fourth node are not limited to the above embodiments.

[0247] In a second aspect, embodiments of the present disclosure provide a resource determination method. Figure 5 is a schematic flow chart illustrating a resource determination method according to an embodiment of the present disclosure. The resource determination method illustrated in this embodiment can be performed by a second node, including but not limited to at least one of the following: a terminal or a core network device. A first node can communicate with the second node, including but not limited to an access network device.

[0248] As shown in FIG5 , the resource determination method may include the following steps:

[0249] In step S501, first information is sent to a first node, wherein the first information is used by the first node to determine relevant resources used by a terminal for direct link positioning.

[0250] It should be noted that the embodiment shown in FIG. 5 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0251] According to an embodiment of the present disclosure, a second node may send first information to a first node, which may be used by the first node to determine relevant resources for direct link positioning of a terminal. Accordingly, the first node may determine relevant resources for direct link positioning of the terminal based on external information, namely, the first information from the second node. This helps ensure that the determined relevant resources for direct link positioning of the terminal are well-suited for the terminal, thereby ensuring a positioning effect achieved by the terminal based on the resources with reference to direct link positioning.

[0252] In some embodiments, the related resources for direct link positioning include at least one of the following:

[0253] Ranging and direct link positioning protocol transmission resources. It should be noted that the ranging and direct link positioning protocol can also be called the direct link positioning protocol;

[0254] Direct link location resources.

[0255] For example, ranging and direct link positioning protocol transmission resources are used by terminals to transmit positioning and direct link related information (for example, interaction of positioning capabilities, discovery of terminals, selection of terminals, negotiation of positioning methods, negotiation of positioning resources, transmission of positioning measurement results, etc.), and direct link positioning resources are used by terminals to send and / or receive reference signals used for positioning in the direct link positioning process (for example, direct link positioning reference signals).

[0256] In some embodiments, the direct link positioning resource includes at least one of the following:

[0257] Direct link positioning reference signal frequency information, such as bandwidth, frequency, etc.

[0259] In some embodiments, the first information includes at least one of the following:

[0260] Direct link positioning request information;

[0261] Authorization information of the terminal.

[0262] It should be noted that when the first information includes direct link positioning request information and terminal authorization information, the direct link positioning request information and the terminal authorization information may come from the same node. In this case, the first node may be one node; and when the direct link positioning request information and the terminal authorization information come from different nodes, in this case, the first node may be multiple nodes, for example, the first node includes a terminal and a core network device.

[0263] In some embodiments, the first information is carried in at least one of the following:

[0264] NGAP message, wherein the first node includes an access network device and the second node includes a core network device;

[0265] F1AP message, wherein the first node includes a gNB-DU in a split radio access network architecture, and the second node includes a gNB-CU or a gNB-CU-CP in a split radio access network architecture;

[0266] XnAP message, wherein the first node includes a target base station in a handover process, and the second node includes a source base station in a handover process, or the first node includes a new serving base station, and the second node includes a last serving base station;

[0267] New Air Interface Positioning Protocol A message, wherein the first node includes an access network device and the second node includes a core network device;

[0269] In some embodiments, the first node includes at least one of the following: an access network device (e.g., a base station), a gNB-DU (Distributed Unit) under a wireless access network separation architecture.

[0270] In some embodiments, the second node includes at least one of the following: an access network device (e.g., a base station), a terminal, a core network device, a gNB-CU under a wireless access network separation architecture, and a gNB-CU-CP under a wireless access network separation architecture.

[0271] The following describes, through several embodiments, a case where the first information includes direct link positioning request information.

[0272] For example, when the first information includes direct link positioning request information, and the first node includes an access network device, and the second node includes a core network device, such as a location management function (LMF), the second node can send the direct link positioning request information to the first node in a new radio positioning protocol A (NR positioning protocol A, NRPPA) message.

[0273] The NRPPA message may be an NRPPA message related to the terminal, for example, the NRPPA message includes at least one of the following: a positioning information request of the terminal, a direct link positioning configuration request of the terminal.

[0274] For example, when the first information includes direct link positioning request information, and the first node includes an access network device, and the second node includes a terminal, the second node may send the direct link positioning request information to the first node in signaling.

[0275] The signaling includes at least one of the following: RRC (Radio Resource Control) signaling, physical layer signaling (such as downlink control information (DCI)), and media access control layer signaling (such as media access control layer control element (MAC CE)).

[0276] For example, when the first information includes direct link positioning request information, and the first node includes a gNB-DU under a wireless access network separation architecture, and the second node includes a gNB-CU or a gNB-CU-CP under a wireless access network separation architecture, the second node can send the direct link positioning request information to the first node in an F1AP (F1 Application Protocol) message.

[0277] The F1AP message may be an F1AP message related to the terminal, for example, the F1AP message includes at least one of the following: a positioning information request of the terminal, and a direct link positioning configuration request of the terminal.

[0278] For example, when the first information includes direct link positioning request information, and the first node includes an access network device, and the second node includes a core network device, such as an Access and Mobility Management Function (AMF), the second node can send the direct link positioning request information to the first node in an NGAP (Next Generation Application Protocol) message.

[0279] The NGAP message may be an NGAP message related to the terminal, for example, the NGAP message includes at least one of the following: a context establishment request of the terminal, a context modification request of the terminal.

[0280] The following describes, through several embodiments, a case where the first information includes authorization information of the terminal.

[0281] For example, when the first information includes authorization information of the terminal, and the first node includes an access network device, and the second node includes a core network device, such as AMF, the second node can send the authorization information of the terminal to the first node in an NGAP message.

[0282] The NGAP message may be an NGAP message related to the terminal, for example, the NGAP message includes at least one of the following: a context establishment request of the terminal, a context modification request of the terminal.

[0283] For example, when the first information includes authorization information of the terminal, and the first node includes a gNB-DU under a wireless access network separation architecture, and the second node includes a gNB-CU or gNB-CU-CP under a wireless access network separation architecture, the second node can send the direct link positioning request information to the first node in an F1AP (F1 Application Protocol) message, and the second node can send the authorization information of the terminal to the first node in the F1AP message.

[0284] The F1AP message may be an F1AP message related to the terminal, for example, the F1AP message includes at least one of the following: a context establishment request of the terminal, and a context modification request of the terminal.

[0285] For example, the terminal can perform switching. When the first information includes the authorization information of the terminal, the first node can include the target base station corresponding to the target cell to which the terminal needs to switch, and the second node can include the source base station corresponding to the source cell where the terminal was located before the switching. The second node can send the authorization information of the terminal to the first node in the XnAP (Xn Application Protocol) message.

[0286] The XnAP message may be an XnAP message related to the terminal, for example, the XnAP message includes a handover request.

[0287] For example, a terminal (e.g., in an inactive state) can change its service base station. When the first information includes the authorization information of the terminal, the first node can include the changed service base station, which can also be called the new service base station. The second node can include the service base station before the terminal is changed, which can also be called the last service base station. The second node can send the authorization information of the terminal to the first node in an XnAP (Xn Application Protocol) message.

[0288] The XnAP message may be an XnAP message related to the terminal, for example, the XnAP message includes: a context feedback message of the terminal.

[0289] The specific content of the direct link positioning request information is exemplarily described below through several embodiments.

[0290] In some embodiments, the direct link positioning request information includes at least one of the following:

[0291] the role of the terminal;

[0292] an identifier of the terminal;

[0293] Task identifier for direct link positioning;

[0294] Service type for direct link positioning;

[0295] Quality of service for direct link positioning;

[0296] Transmission characteristic information of the direct link positioning reference signal;

[0297] Direct link positioning reference signal transmission stop information;

[0298] The cell information where the direct link positioning terminal is located.

[0299] In some embodiments, the role of a terminal (also referred to as the type of terminal) refers to the role of the terminal in a direct link positioning process or task. For example, the role includes at least one of the following: anchor terminal (anchor UE), target terminal (target UE), location terminal (location UE), server terminal (server UE); for example, the role includes at least one of the following: server terminal only (server UE only) or server terminal or non-direct link positioning terminal, direct link positioning terminal (SL Positioning UE), wherein the direct link positioning terminal includes a terminal participating in direct link positioning, such as an anchor terminal and a target terminal. The first node can determine relevant resources for direct link positioning for the terminal based on the role of the terminal.

[0300] It should be noted that, in the embodiments of the present disclosure, the anchor terminal, the target terminal, and the location terminal may also be referred to as a reference terminal (reference UE).

[0301] In some embodiments, the role of the terminal can be classified according to whether it participates in direct link positioning (i.e., whether it receives and / or sends direct link positioning reference signals). For example, a terminal participating in direct link positioning (e.g., anchor UE, location UE, or target UE) needs to be allocated direct link positioning reference signal resources, while a terminal not participating in direct link positioning (e.g., server UE or client UE) cannot be allocated direct link positioning reference signal resources.

[0302] In some embodiments, the role of the terminal is classified according to whether it receives or sends a direct link positioning reference signal. For example, a terminal that needs to send a direct link positioning reference signal needs to be allocated corresponding direct link positioning reference signal resources, and a terminal that only receives a direct link positioning reference signal cannot be allocated direct link positioning reference signal resources (e.g., resources for sending a direct link positioning reference signal).

[0303] In some embodiments, the role of the terminal can be classified according to whether it needs to interact through the RSPP protocol. For example, a terminal that needs to interact with the RSPP protocol needs to be allocated corresponding RSPP resources, while a terminal that does not need to interact with the RSPP protocol (for example, a terminal that is only responsible for sending and receiving direct link positioning reference signals and interacts through the network) cannot be allocated RSPP protocol resources.

[0304] In some embodiments, the role of the terminal can be classified according to the reception and / or transmission of the direct link positioning reference signal, for example, the role of the terminal includes at least one of the following: direct link TP, direct link RP, direct link TRP.

[0305] In some embodiments, the terminal identifier can be used to uniquely identify a specific terminal. For example, the terminal identifier can be an identifier (ID) of a cell where the terminal is located, or a Cell-Radio Network Temporary Identifier (C-RNTI) assigned to the terminal. The first node can determine relevant resources for direct link positioning for the terminal based on the terminal identifier.

[0306] In some embodiments, a direct link positioning task (Transaction) identifier, also known as a service identifier or a transaction identifier, may be used to identify a specific direct link positioning task. The first node may determine relevant resources for direct link positioning for the terminal based on the direct link positioning task identifier.

[0307] In some embodiments, a service type for direct link positioning may be used to indicate a service type used for direct link positioning, where the service type includes at least one of a V2X (vehicle to everything) and a ProSe (Proximity Services) identifier. The first node may determine, for the terminal, relevant resources for direct link positioning based on the service type for direct link positioning.

[0308] In some embodiments, the quality of service of the direct link positioning may be used to indicate the quality of service required for the direct link positioning. The first node may determine, for the terminal, relevant resources for direct link positioning based on the quality of service of the direct link positioning.

[0309] In some embodiments, the quality of service of the direct link positioning includes a range requirement, and the first node may determine relevant resources for direct link positioning for the terminal according to the quality of service of the direct link positioning.

[0310] In some embodiments, direct link positioning reference signal transmission stop information can be used by the first node to determine when to release a specific direct link positioning reference signal resource allocated to the terminal or to determine the time to allocate a specific direct link positioning reference signal resource to the terminal. The first node can determine relevant resources for direct link positioning for the terminal based on the direct link positioning reference signal transmission stop information.

[0311] In some embodiments, the cell information where the direct link positioning terminal is located can also be referred to as the information of the cell where the terminal participating in the direct link positioning is located. The first node can send the relevant resources used by the terminal for direct link positioning to the third node based on the cell information where the direct link positioning terminal is located.

[0312] For example, the first node can determine that the base station corresponding to the cell where the anchor terminal participating in the direct link positioning is located is the first node, and the base station corresponding to the cell where the target terminal participating in the direct link positioning is located is the third node based on the cell information where the direct link positioning terminal is located. Then, after the first node determines the relevant resources used by the anchor terminal for direct link positioning, it can send information about the relevant resources used by the anchor terminal for direct link positioning to the third node, so that when the third node determines the relevant resources used by the target terminal for direct link positioning, it can avoid conflict with the relevant resources used by the anchor terminal for direct link positioning.

[0313] In some embodiments, the transmission characteristic information of the direct link positioning reference signal includes at least one of the following: cell information; bandwidth information; transmission type; transmission information; start time; duration; and end time. The first node may determine, for the terminal, relevant resources for direct link positioning based on the transmission characteristic information of the direct link positioning reference signal to improve resource utilization efficiency and avoid interference.

[0314] In some embodiments, the authorization information of the terminal includes at least one of the following:

[0315] Authorizing role information of the terminal;

[0316] Authorized transmission quality of service information;

[0317] Authorized positioning service quality information.

[0318] In some embodiments, the role information of the authorized terminal can be used to indicate whether the first node terminal is authorized for a specific role. When the terminal is authorized for a specific role, the first node can determine the services, resources, service quality and other related information corresponding to the specific role, and then determine the relevant resources for direct link positioning for the terminal based on these relevant information.

[0319] It should be noted that, in addition to the several roles described in the preceding embodiments, the role information of the authorized terminal may also include other roles. For example, roles permitted to receive and / or transmit specific resources may include at least one of the following: terminals permitted to receive direct link positioning reference signal resources, terminals permitted to transmit direct link positioning reference signal resources, terminals permitted to both receive and transmit direct link positioning reference signal resources, and terminals permitted to use ranging and direct link positioning protocol resources. Distinguishing terminals based on these roles facilitates more reasonable and accurate resource allocation by the first node. For example, for terminals permitted to receive direct link positioning reference signal resources, the first node may allocate direct link positioning reference signal resources for reception; and for terminals permitted to transmit direct link positioning reference signal resources, the first node may allocate direct link positioning reference signal resources for transmission.

[0320] In some embodiments, the authorized transmission quality of service information may be used by the first node to determine direct link positioning protocol transmission resources for the terminal.

[0321] For example, the authorized transmission service quality information may include: a mapping table between direct link positioning services and direct link transmission service quality parameters, and the type of the direct link positioning service may be, for example, V2X or ProSe.

[0322] In some embodiments, the first node may determine the direct link positioning protocol transmission resources based on the authorized transmission service quality information and the direct link positioning service type;

[0323] In some embodiments, the first node may use the authorized transmission quality of service information as the default or default quality of service of the terminal to determine the direct link positioning protocol transmission resources of the terminal in a direct link positioning task.

[0324] In some embodiments, the authorized positioning service quality information may be used by the first node to determine a direct link positioning reference signal resource for the terminal.

[0325] For example, the authorized positioning service quality information may include: a mapping table between direct link positioning services and direct link positioning service quality parameters, and the type of the direct link positioning service may be, for example, V2X or ProSe.

[0326] In some embodiments, the first node may determine the direct link positioning reference signal resource according to the authorized positioning service quality information and the direct link positioning service type;

[0327] In some embodiments, the first node may use the authorized positioning service quality information as the default or default service quality of the terminal to determine the direct link positioning reference signal resources of the terminal in an SL positioning task.

[0328] In some embodiments, the method further comprises at least one of the following:

[0329] receiving configuration information of related resources for direct link positioning sent by the first node;

[0330] Receive the allocation failure information of the related resources used for direct link positioning sent by the first node.

[0331] In some embodiments, the first node determines, based on the first information, relevant resources for direct link positioning of the terminal. This may include, in addition to allocating relevant resources for direct link positioning to the terminal, also determining not to allocate relevant resources for direct link positioning to the terminal. When allocating relevant resources for direct link positioning to the terminal, specific ranging and direct link positioning protocol transmission resources, and / or direct link positioning resources, may be determined based on the first information.

[0332] For example, the first node determines to allocate relevant resources for direct link positioning to the terminal based on the first information, and the second node can receive the configuration information of the relevant resources for direct link positioning determined by the first node. The configuration information can serve as a response message to the first information, so that the second node can determine the relevant resources for direct link positioning of the terminal based on the configuration information.

[0333] For example, the first node determines not to allocate resources related to direct link positioning to the terminal based on the first information. The second node may receive information from the first node regarding a failure to allocate resources related to direct link positioning. The allocation failure information may serve as a response message to the first information, so that the second node may determine, based on the allocation failure information, that allocation of resources related to direct link positioning to the terminal has failed. The failure information may also carry a specific reason for the failure, such as authorization failure or resource unavailability.

[0334] In some embodiments, the configuration information and / or the allocation failure information is carried in at least one of the following:

[0335] New Air Interface Positioning Protocol A message, wherein the first node includes an access network device and the second node includes a core network device;

[0336] NGAP message, wherein the first node includes an access network device and the second node includes a core network device;

[0337] signaling, wherein the first node includes an access network device and the second node includes the terminal;

[0338] F1AP message, wherein the first node includes a gNB-DU under a wireless access network separation architecture, and the second node includes a gNB-CU or gNB-CU-CP under a wireless access network separation architecture.

[0339] For example, the first node includes an access network device, the second node includes an LMF, and the first node can send configuration information or allocation failure information to the second node in an NRPPA message.

[0340] The NRPPA message may be an NRPPA message related to the terminal. For example, when it is determined that relevant resources for direct link positioning are allocated to the terminal, the NRPPA message includes at least one of the following: a positioning information feedback message and a direct link positioning configuration feedback message; for example, when it is determined that relevant resources for direct link positioning are not allocated to the terminal, the NRPPA message includes at least one of the following: a positioning information request failure message and a direct link positioning configuration failure message.

[0341] For example, the first node includes an access network device, and the second node includes a terminal. The first node may send configuration information or allocation failure information to the second node in signaling. The signaling may be, for example, RRC signaling, DCI, MAC CE, etc.

[0342] For example, the first node includes a gNB-DU under a wireless access network separation architecture, and the second node includes a gNB-CU or gNB-CU-CP under a wireless access network separation architecture. The first node can send configuration information or allocation failure information to the second node in an F1AP message.

[0343] The F1AP message may be an F1AP message related to the terminal. For example, when it is determined that relevant resources for direct link positioning are allocated to the terminal, the F1AP message includes at least one of the following: a positioning information feedback message and a direct link positioning configuration feedback message; for example, when it is determined that relevant resources for direct link positioning are not allocated to the terminal, the F1AP message includes at least one of the following: a positioning information request failure message and a direct link positioning configuration failure message.

[0344] For example, the first node includes an access network device, and the second node includes an AMF. The first node may send configuration information or allocation failure information to the second node in an NGAP message. The NGAP message may be an NGAP message related to the terminal. For example, when determining to allocate relevant resources for direct link positioning to the terminal, the NGAP message includes at least one of the following: a context establishment feedback message for the terminal, or a context modification feedback message for the terminal. For example, when determining not to allocate relevant resources for direct link positioning to the terminal, the NGAP message includes at least one of the following: a context establishment failure message for the terminal, or a context modification failure message for the terminal.

[0345] It should be noted that when the second node is a terminal, the terminal can determine the relevant resources for direct link positioning based on the configuration information, and then participate in the direct link positioning based on the determined relevant resources; when the second node is not a terminal, the second node can, upon receiving the configuration information, provide resource configuration information as needed, or send the configuration information to the terminal for the terminal to determine the relevant resources for direct link positioning, or, upon receiving the allocation failure information, the second node can provide resource allocation failure information as needed, or send the allocation failure information to the terminal for the terminal to determine that the allocation of relevant resources for direct link positioning has failed.
