[0072] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0073] In the embodiments of the present disclosure, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0074] In order to solve the above problems, the embodiments of the present disclosure provide a positioning method, an apparatus and a storage medium, which obtain a positioning request sent by a communication device, and the positioning request is used to instruct the UE to send positioning information on the direct communication link sidelink interface. Thus, the sidelink interface resources in the UE are saved, and the efficiency of positioning on the sidelink interface is greatly improved.

[0075] The positioning method, device and storage medium of this embodiment are described below with reference to the accompanying drawings.

[0076] Among them, it should be noted that the technical solution provided by the embodiment of the present disclosure can be applicable to a variety of systems, especially 5G systems. For example, the applicable system can be a global system of mobilecommunication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new air interface (NR) system, etc. These various systems include terminal equipment and network side equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0077] Figure 1 It is a flow chart of a positioning method provided according to an embodiment of the present disclosure, and the positioning method is applied to a user equipment UE.

[0078] like Figure 1 As shown, the method includes:

[0079] Step 101: Acquire a positioning request sent by a communication device, where the positioning request is used to instruct the UE to send positioning information on a direct communication link sidelink interface.

[0080] The communication device may be any of the following types of devices: UE, base station and positioning server.

[0081] It is understandable that the positioning request may be in the form of a signal or a message, etc., and the present disclosure does not limit this.

[0082] The positioning request may include at least one of the following information: the identification of the communication device, the type of positioning information, the identification of the positioning information, the method of sending the positioning information, the duration of sending the positioning information, the period of sending the positioning information, the beam direction of sending the positioning information, the resource index number corresponding to the positioning information, and the message name of the request, wherein different message names correspond to different positioning information.

[0083] Among them, the identification of the communication equipment can be in various forms, such as UE1, UE3, base station a, base station C, LMF1, LMF5A, etc., which can represent the uniqueness of the communication identification, and this disclosure does not limit this.

[0084] In addition, the types of positioning information may be various, such as Global Navigation Satellite System (GNSS) positioning assistance data, or specific data of a GNSS positioning assistance data center, such as GNSS reference time assistance data, GNSS reference position assistance data, etc., which are not limited in the present disclosure.

[0085] In addition, the identifier of the positioning information can represent the uniqueness of the positioning information, that is, it can indicate whether it is positioning auxiliary information, a positioning pilot signal, or other positioning information, etc., which is not limited in the present disclosure.

[0086] It is understandable that there may be multiple ways to send positioning information, such as unicast, multicast or broadcast, and the present disclosure does not limit this.

[0087] In addition, the duration of sending the positioning information can be any duration, such as 10ms, 1s, etc., and the present disclosure does not limit this.

[0088] It is understandable that the period for sending positioning information may also be set according to actual needs, such as sending once every 5 minutes, or once every 3 minutes, etc., and the present disclosure does not limit this.

[0089] In addition, the resource index number corresponding to the positioning information may also be pre-set content, and the resources may be of various types, such as time domain, frequency domain, spatial domain, etc., which is not limited in the present disclosure.

[0090] It can be understood that the message name of the request can be one or more, such as message 2, message A, message d, etc. Different message names can correspond to different positioning information. For example, the message name is message 2, which may correspond to auxiliary information related to the positioning pilot signal sent by the NR-RAN node. Or the message name is message A, which may correspond to auxiliary information related to the positioning pilot signal sent on the wireless interface (Uu interface). Or the message name is message d, which may correspond to auxiliary information related to the positioning pilot signal sent on the sidelink interface, etc., which is not limited in this disclosure.

[0091] It is understandable that the positioning request may include one message name, or may also include multiple message names, etc., which is not limited in the present disclosure.

[0092] In addition, the positioning information may be at least one of the following information: positioning auxiliary information and a positioning pilot signal.

[0093] The positioning assistance information may be information used to assist the communication device in performing positioning-related processes, such as informing the communication device to monitor the time domain / frequency domain position of the positioning pilot signal.

[0094] In addition, when the positioning request is in the form of a signal, it may be a designated signal, and the designated signal may correspond to at least one of the following: the type of positioning information, the message containing the positioning information, and the resource corresponding to the positioning information.

[0095] It is understandable that the designated signal and the corresponding related positioning information may be content agreed upon in advance by the user equipment UE and the communication device. For example, when the positioning request is designated signal 1, it may correspond to GNSS-related auxiliary information, or, when the positioning request is designated signal 2, it may correspond to auxiliary information related to the positioning pilot signal sent by the NR-RAN node, etc. This disclosure does not limit this.

[0096] For example, the UE obtains a positioning request sent by the communication device, which may be in the form of a message, which may include LMF, GNSS-related auxiliary information, etc., and then the UE can quickly send GNSS-related auxiliary information to the LMF on the sidelink interface according to the positioning request.

[0097] Alternatively, the UE obtains the positioning request sent by the communication device, which may be designated signal 2. According to the agreement, designated signal 2 corresponds to auxiliary information related to the positioning pilot signal sent by the NR-RAN node. After that, the UE can quickly send the auxiliary information related to the positioning pilot signal sent by the NR-RAN node to the surrounding in the form of broadcast on the sidelink interface according to the positioning request. Alternatively, the auxiliary information related to the positioning pilot signal sent by the NR-RAN node can also be sent to the surrounding in the form of multicast.

[0098] It should be noted that the above examples are only illustrative and cannot be used as limitations on the positioning request, content of positioning information, and sending method in the embodiments of the present disclosure.

[0099] Step 102: Send positioning information on the sidelink interface.

[0100] The positioning information may be at least one of the following information: positioning auxiliary information, positioning pilot signal, etc., which is not limited in the present disclosure.

[0101] For example, the UE may send relevant positioning information on the sidelink interface based on the acquired positioning request and the information carried in the positioning request.

[0102] Furthermore, the UE may also send the positioning information required by the base station on the sidelink interface according to the sending mode, resources used for sending, sending duration, and / or sending period and other information carried in the positioning request.

[0103] Alternatively, the UE may send a positioning pilot signal on demand on a sidelink interface based on the acquired positioning request and information carried in the positioning request.

[0104] For example, the positioning request obtained by the UE may be "request to send positioning pilot signal 2 on the sidelink interface", so that the positioning pilot signal 2 may be sent on the sidelink interface based on the positioning request.

[0105] Alternatively, according to the acquired positioning request, only positioning pilot signals in certain beam directions may be sent on the sidelink interface.

[0106] Furthermore, the positioning pilot signal required by the base station may be sent according to the sending mode, resources used for sending, sending duration, and / or sending period and other information carried in the request message.

[0107] It should be noted that the above examples are only illustrative and cannot be used as a limitation on sending positioning information on the sidelink interface in the embodiments of the present disclosure.

[0108] The embodiment of the present disclosure obtains a positioning request sent by a communication device, where the positioning request is used to instruct the UE to send positioning information on a direct communication link sidelink interface. The positioning information can then be sent on the sidelink interface, thereby saving sidelink interface resources in the UE and greatly improving the efficiency of positioning on the sidelink interface.

[0109] The following takes the communication device as a base station as an example. Figure 2 The positioning method provided by the present disclosure is further described.

[0110] Step 201: obtain a positioning request sent by a base station, where the positioning request is used to instruct the UE to send positioning information on a direct communication link sidelink interface.

[0111] Step 202: Send positioning information on the sidelink interface according to the positioning request.

[0112] It should be noted that the contents related to the positioning request can refer to the description of other embodiments of the present disclosure and will not be repeated here.

[0113] In addition, the positioning information may be positioning auxiliary information, positioning pilot signal, etc., which is not limited in the present disclosure.

[0114] For example, the positioning request sent by the base station and obtained by the UE may be "request to send positioning assistance information".

[0115] Optionally, the positioning request may carry the type of positioning assistance information requested to be sent, which may be one or more types, and the present disclosure does not limit this.

[0116] For example, the positioning request may also be a request for the UE to send GNSS positioning assistance data, or a request for the UE to send a specific data in the GNSS positioning assistance data (such as GNSS reference time assistance data, GNSS earth position parameter assistance data). Or the positioning request may also be a request for the UE to send auxiliary information related to the NR-RAN node sending the positioning pilot signal; or a request for auxiliary information related to the positioning pilot signal sent on the Uu interface; or a request for auxiliary information related to the positioning pilot signal sent on the sidelink interface, etc., which is not limited in this disclosure.

[0117] In addition, the positioning request may also include a message name of the request. It is understandable that different message names may correspond to different positioning information, and the positioning request may include one message name, or may also include multiple message names, which is not limited in the present disclosure.

[0118] For example, message 1 may include GNSS-related auxiliary information, message 2 may include auxiliary information related to the positioning pilot signal sent by the NR-RAN node, message 3 may be auxiliary information related to the positioning pilot signal sent on the Uu interface, and message 4 may be auxiliary information related to the positioning pilot signal sent on the sidelink interface. The positioning request sent by the base station obtained by the UE may be a request to send message 1, or the positioning request sent by the base station obtained by the UE may be a request to send message 1, message 2, and message 4, etc., which is not limited in this disclosure.

[0119] In addition, the positioning request may also include a sending method, which may be broadcast, multicast or a dedicated channel, etc., which is not limited in the present disclosure.

[0120] It is understandable that the positioning request also includes the resources used for sending, which may be in the time domain, frequency domain, and / or spatial domain, etc., and the present disclosure does not limit this.

[0121] For example, the UE can send relevant positioning information on the sidelink interface by obtaining the "request to send positioning assistance information" sent by the base station and the information carried in the request.

[0122] It should be noted that “requesting to send positioning assistance information” is only an illustrative description and cannot be used as a limitation on the positioning request sent by the base station in the embodiment of the present disclosure.

[0123] Furthermore, the UE may also send the positioning information required by the base station on the sidelink interface according to the sending mode, resources used for sending, sending duration, and / or sending period and other information carried in the positioning request.

[0124] In the disclosed embodiment, after obtaining the positioning request sent by the base station, the UE can send positioning assistance information when the positioning assistance information is needed, thereby saving the overhead on the sidelink interface and improving efficiency.

[0125] In addition, the positioning request may also be a positioning pilot signal. For example, the positioning request sent by the base station acquired by the UE may be "requesting to send a positioning pilot signal on the sidelink interface".

[0126] Furthermore, the positioning request may carry an identifier of the positioning pilot signal requested to be sent. For example, if the identifier of the positioning pilot signal in the positioning request obtained by the UE is 1, it may instruct the UE to send the positioning pilot signal with the identifier 1 on the sidelink interface.

[0127] It should be noted that the above-mentioned identifier 1 is only an example and cannot be used as a limitation on the identifier of the positioning pilot signal in the embodiment of the present disclosure.

[0128] In addition, the positioning request may also carry the type of positioning pilot signal requested to be sent. For example, one or more positioning pilot signals that can be sent on the sidelink interface may be defined, where different positioning pilot signals can meet different application scenarios. For example, positioning pilot signal 1 is suitable for commercial indoor scenarios, positioning pilot signal 2 is suitable for industrial deployment scenarios, and so on. The base station currently requires an industrial deployment scenario, and the positioning request sent by the base station obtained by the UE may be "request to send positioning pilot signal 2 on the sidelink interface", which is not limited in this disclosure.

[0129] In addition, the positioning request may also carry the beam direction of the positioning pilot signal requested to be sent. For example, when the UE sends the positioning pilot signal using beam scanning on the sidelink interface, the positioning request sent by the base station obtained by the UE may be "requesting the UE to send the positioning pilot signal only on a specific beam or a certain set of beams", thereby reducing the overhead of the positioning pilot signal and also reducing the beams monitored by the receiving UE.

[0130] It should be noted that the above examples are only illustrative and cannot be used as a limitation on the content of the positioning request in the embodiments of the present disclosure.

[0131] It is understandable that the positioning request may also carry the resources used for sending, such as time domain, frequency domain and / or spatial domain, sending duration, sending period, etc., which is not limited in the present disclosure.

[0132] Afterwards, the UE can send a positioning pilot signal on the sidelink interface as needed based on the positioning request sent by the base station and the information carried in the positioning request.

[0133] For example, the UE may send the positioning pilot signal 2 on the sidelink interface according to the acquired “request to send the positioning pilot signal 2 on the sidelink interface” sent by the base station.

[0134] Alternatively, according to the acquired positioning request, only positioning pilot signals in certain beam directions may be sent on the sidelink interface.

[0135] Furthermore, the positioning pilot signal required by the base station may be sent according to the sending mode, resources used for sending, sending duration, and / or sending period and other information carried in the request message.

[0136] In the disclosed embodiment, the above-mentioned method can save the overhead of sending the positioning pilot signal on the sidelink interface, and also reduce the range of the sidelink positioning pilot signal monitored by the UE, thereby improving efficiency.

[0137] In addition, when the communication device is a base station or a positioning server, the positioning request may also include positioning information.

[0138] It is understandable that the positioning information may be acquired and stored in advance by the UE, or may be sent to the UE by the base station or the positioning server in a positioning request. The base station may send the positioning information to the UE through one positioning request, or may send the positioning information to the UE through multiple positioning requests, which is not limited in this disclosure.

[0139] It should be noted that the communication equipment base station in the embodiment of the present disclosure may also be replaced with an LMF, and the present disclosure does not limit this.

[0140] In an embodiment of the present disclosure, a UE obtains a positioning request sent by a base station, where the positioning request is used to instruct the UE to send positioning information on a sidelink interface of a direct communication link. Thereafter, the positioning information can be sent on the sidelink interface according to the positioning request, thereby saving sidelink interface resources in the UE and greatly improving the efficiency of positioning on the sidelink interface.

[0141] In a possible implementation, the UE may also send a positioning-related indication message that it can provide on the sidelink interface, so that other UEs around the UE can send a positioning request to the UE when there is a positioning requirement. Figure 3 The above process is described in detail.

[0142] Step 301: Send an indication message on a sidelink interface, wherein the indication message is used to indicate information of a positioning signal that can be provided by a user equipment UE.

[0143] Among them, the indication message may include at least one of the following information: whether to send positioning information on the sidelink interface, the type of positioning information sent on the sidelink interface, the name of the sending message associated with each positioning information, the corresponding resource index number of the positioning information sent on the sidelink interface, the corresponding resource of the positioning information sent on the sidelink interface, the sending method of the positioning information, the signal identifier associated with each positioning information, the name of the request message associated with each positioning information, the type of positioning information corresponding to each positioning request signal, the resource of the positioning information corresponding to each positioning request signal, and the resource index number of the positioning information corresponding to each positioning request signal.

[0144] In addition, there may be multiple transmission modes, such as dedicated channel, unicast, multicast, broadcast, etc., which are not limited in the present disclosure.

[0145] In addition, the information of the positioning signal that the UE can provide may be a type of positioning assistance information, which may be one or more types, and the present disclosure does not limit this.

[0146] For example, the UE can inform the surrounding UEs that it can provide GNSS positioning assistance data; or the UE can inform the surrounding UEs that it can provide a specific data in the GNSS positioning assistance data (such as GNSS reference time assistance data, GNSS reference position assistance data). Or the UE can inform the surrounding UEs that it can provide auxiliary information related to the positioning pilot signal sent by the NR-RAN node. Or the UE can inform the surrounding UEs that it can provide auxiliary information related to the positioning pilot signal sent by the UE on the Uu interface, or the UE can inform the surrounding UEs that it can provide auxiliary information related to the positioning pilot signal sent by the UE on the sidelink interface, etc. This disclosure is not limited to this.

[0147] In addition, the information of the positioning signal that the UE can provide can also be in the form of a message. For example, message 1 includes GNSS-related auxiliary information, message 2 includes auxiliary information related to the positioning pilot signal sent by the NR-RAN node, message 3 is a request for auxiliary information related to the positioning pilot signal sent on the Uu interface, and message 4 is a request for auxiliary information related to the positioning pilot signal sent on the sidelink interface. If the UE stores message 1 and message 4, it can inform the surrounding UEs of the contents of message 1 and message 4 on the sidelink interface, and this disclosure does not limit this.

[0148] It is understandable that the UE may also provide information on whether it is sending on the sidelink interface and the sending method, which may be broadcast, multicast, or unicast, etc., and the present disclosure does not limit this.

[0149] In addition, the UE may also provide a correspondence between the type of positioning request signal and positioning assistance information or the message corresponding to the positioning assistance information. For example, positioning request signal 1 corresponds to GNSS reference time assistance data, and positioning request signal 2 corresponds to GNSS reference position assistance data. Or positioning request signal 3 corresponds to GNSS positioning assistance data, and positioning request signal 4 corresponds to auxiliary information related to the positioning pilot signal sent by the NR-RAN node, etc. This disclosure does not limit this.

[0150] For example, the positioning signal information that the UE can provide may be GNSS-related auxiliary information that can be sent on the sidelink interface, such as GNSS reference time assistance data, or GNSS positioning assistance data, etc. The UE can send the positioning signal information that it can provide to the surrounding in the form of broadcast on the sidelink interface.

[0151] It should be noted that the above examples are only illustrative and cannot be used as a limitation on the positioning signal information that the UE can provide in the embodiments of the present disclosure.

[0152] Optionally, the indication message sent by the UE on the sidelink interface may also be a positioning pilot signal. The UE may inform other surrounding UEs of relevant information of the positioning pilot signal that it may send.

[0153] For example, the UE can inform other UEs around it and send a positioning pilot signal on the sidelink interface.

[0154] Alternatively, the UE may inform other UEs around it of the type of positioning pilot signals that can be sent on the sidelink interface. For example, one or more positioning pilot signals sent on the sidelink interface may be defined, and different positioning pilot signals meet different application scenarios. For example, positioning pilot signal 1 is applicable to commercial indoor scenarios, positioning pilot signal 2 is applicable to industrial deployment scenarios, etc., which is not limited in the present disclosure.

[0155] Alternatively, the UE may inform other UEs around it that it may send a resource configuration of a positioning pilot signal on the sidelink interface, which may be one set or multiple sets. For example, a set of positioning pilot signal resource configurations (recorded as configuration 1) may be defined, corresponding to the configuration of positioning pilot signals with a relatively dense period and / or a relatively large bandwidth; a set of positioning signal resource configurations (recorded as configuration 2) may be defined, corresponding to the configuration of positioning pilot signals with a relatively sparse period and / or a relatively small bandwidth, etc., and the present disclosure does not limit this.

[0156] Alternatively, the UE may inform other UEs around it of the relationship between the positioning request signal and the positioning pilot signal type and / or resource configuration. For example, positioning request signal 1 corresponds to positioning pilot signal 1, and positioning request signal 2 corresponds to positioning pilot signal 2. Or positioning request signal 1 corresponds to positioning pilot signal 1 under configuration 1, and positioning request signal 2 corresponds to positioning pilot signal 1 under configuration 2, etc., which is not limited in the present disclosure.

[0157] It should be noted that the above examples are only illustrative and cannot be used as a limitation on sending indication messages on the sidelink interface in the embodiments of the present disclosure.

[0158] Step 302: Acquire positioning requests sent by other UEs.

[0159] Among them, the other UE may be one, or may be multiple, which is not limited in the present disclosure.

[0160] In the embodiment of the present disclosure, if the location request received is sent by another UE, corresponding location information can be sent according to the location request. If multiple other UEs are received, they may receive different location requests at the same time according to different links or different channels, or they may receive different location requests at different times, which is not limited in the present disclosure.

[0161] In addition, the positioning request may be a designated signal, and the designated signal may correspond to at least one of the following: a type of positioning information, a message containing the positioning information, and a resource corresponding to the positioning information.

[0162] Among them, the designated signal and its corresponding content may be agreed upon in advance by the communication device and the UE. For example, it has been agreed in advance that signal 1 corresponds to GNSS reference time assistance data, signal 2 corresponds to GNSS positioning assistance data, etc. This disclosure does not limit this.

[0163] For example, the acquired positioning request may be "request to send positioning assistance information".

[0164] Among them, the positioning request may be a signal. Furthermore, the positioning request may be a request signal sent in accordance with the corresponding relationship between the positioning request signal and the type of positioning assistance information or the message corresponding to the positioning assistance information, combined with its own needs. For example, if other UEs expect to receive GNSS positioning assistance data, then other UEs can use request signal 1 to send a request to the UE, and the positioning request obtained by the UE may be request signal 1, which is not limited in this disclosure.

[0165] Or the positioning request may also be a message. Furthermore, it may carry the type of positioning assistance information requested to be sent, which may be one or more types. For example, the positioning request may be for requesting the UE to send GNSS positioning assistance data, or the positioning request may be for requesting the UE to send GNSS reference time assistance data, GNSS earth position parameter assistance data, etc. Or the positioning request may be for requesting the UE to send auxiliary information related to the positioning pilot signal sent by the NR-RAN node. Or the positioning request may be for requesting the auxiliary information related to the positioning pilot signal sent on the Uu interface, or for requesting the auxiliary information related to the positioning pilot signal sent on the sidelink interface, etc., which is not limited in the present disclosure.

[0166] It is understandable that the positioning request may also include a sending method, such as broadcast, multicast, or unicast, etc., which is not limited in the present disclosure.

[0167] In addition, the positioning request may also include a sending duration, a sending cycle, etc., which is not limited in the present disclosure.

[0168] Step 303: Send positioning information on the sidelink interface according to the positioning request.

[0169] Among them, the UE can send relevant positioning assistance information on the sidelink interface according to the acquired positioning request and the information carried in the request. Further, the UE can send the positioning assistance information required in the positioning request according to the sending mode, the resources used for sending, the sending duration, and / or the sending period and other information carried in the request message.

[0170] Optionally, after sending the request, listen for the required positioning assistance information.

[0171] In the disclosed embodiment, the UE sends positioning information on the sidelink interface according to the acquired positioning request, which can save the overhead of sending positioning auxiliary information on the sidelink and improve efficiency.

[0172] Alternatively, the UE may send a positioning pilot signal on demand on the sidelink interface based on the acquired positioning request and the information carried in the request. One possible approach may be that the UE determines the type of positioning pilot signal sent on the sidelink interface, the resources used, and other information based on the positioning requests of multiple other UEs around it and the content in the positioning requests, and sends the positioning pilot signal on the sidelink interface.

[0173] For example, the UE may send positioning pilot signal 2 on the sidelink interface according to the obtained positioning request. Or, according to the obtained positioning request, only the positioning pilot signal in certain beam directions may be sent on the sidelink interface. Furthermore, the UE may also send the required positioning pilot signal according to the information such as the sending mode, the resources used for sending, the sending duration, and / or the sending period carried in the positioning request.

[0174] It should be noted that the above examples are only illustrative and cannot be used as a limitation on the sending of positioning pilot signals, etc. in the embodiments of the present disclosure.

[0175] Optionally, after sending the positioning request, the UE may monitor the required positioning pilot signal.

[0176] In the disclosed embodiment, the above method can reduce the overhead of sending positioning pilot signals on the sidelink, and also reduce the beams monitored by the receiving UE, thereby improving efficiency.

[0177] In the embodiment of the present disclosure, an indication message is sent on the sidelink interface, the indication message is used to indicate the information of the positioning signal that the UE can provide, and then a positioning request sent by the communication device is obtained, and then the positioning information is sent on the sidelink interface according to the positioning request. In this way, the sidelink interface resources in the UE can be further saved, and the efficiency of positioning on the sidelink interface can be greatly improved.

[0178] In a possible implementation, if the current UE does not store relevant positioning information and needs to be positioned, a positioning request can be sent to the communication device. Figure 4 The above process is further explained.

[0179] Step 401: Send a positioning request to a communication device.

[0180] The communication equipment may be a UE, a base station and a positioning server.

[0181] In addition, the positioning request may be a message, or a signal, etc., which is not limited in the present disclosure.

[0182] In the disclosed embodiment, if the current UE does not have relevant positioning information and needs to be positioned, a positioning request may be sent to other communication devices.

[0183] For example, the current UE can directly send "GNSS positioning assistance data required" to the communication device. Alternatively, the corresponding signal can be sent according to the correspondence between the signal and the positioning information agreed in advance. For example, signal 1 corresponds to the auxiliary information related to the positioning pilot signal sent by the NR-RAN node, and signal 2 corresponds to the auxiliary information related to the positioning pilot signal sent on the sidelink interface. If the current UE needs to send auxiliary information related to the positioning pilot signal sent by the NR-RAN node, it can directly send signal 1 to the communication device.

[0184] It should be noted that the above examples are only illustrative and cannot be used as a limitation on sending a positioning request to a communication device in the embodiments of the present disclosure.

[0185] Optionally, if the communication device is another UE, the other UE may send corresponding positioning information to the current UE on the sidelink interface according to the acquired positioning request.

[0186] Optionally, if the communication device is a base station, the base station may forward the acquired positioning request to other UEs around, and the other UEs around send positioning information to the current UE. Alternatively, the base station may also directly send the corresponding positioning information to the current UE according to the acquired positioning request, which is not limited in the present disclosure.

[0187] Optionally, if the communication device is an LMF, the LMF may forward the acquired positioning request to other surrounding UEs, and the other surrounding UEs may send positioning information to the current UE. Alternatively, the LMF may also directly send the corresponding positioning information to the current UE based on the acquired positioning request, which is not limited in the present disclosure.

[0188] Step 402: Receive positioning information sent by other UEs on the sidelink interface.

[0189] Among them, the base station and LMF can also send corresponding positioning requests to other UEs, so that the current UE can receive positioning information sent by other UEs on the sidelink interface.

[0190] In the disclosed embodiment, the UE sends a positioning request to the communication device, and then can receive positioning information sent by other UEs on the sidelink interface, so that the current UE can perform positioning according to the received positioning information. Figure 5 It is a flowchart of a positioning method provided according to another embodiment of the present disclosure, and the positioning method is applied to a communication device.

[0191] like Figure 5 As shown, the method includes:

[0192] Step 501: Send a positioning request to a first UE, wherein the positioning request is used to instruct the first UE to send positioning information on a sidelink interface.

[0193] The communication device may be any of the following types of devices: UE, base station and positioning server, which is not limited in the present disclosure.

[0194] It is understandable that the positioning request may be in the form of a signal or a message, etc., and the present disclosure does not limit this.

[0195] The positioning request may include at least one of the following information: the identification of the communication device, the type of positioning information, the identification of the positioning information, the method of sending the positioning information, the duration of sending the positioning information, the period of sending the positioning information, the beam direction of sending the positioning information, the resource index number corresponding to the positioning information, and the message name of the request, wherein different message names correspond to different positioning information.

[0196] Among them, the identification of the communication equipment can be in various forms, such as UE1, UE3, base station a, base station C, positioning server 1, positioning server 5A, etc., which can represent the uniqueness of the communication identification, and this disclosure does not limit this.

[0197] In addition, the type of positioning information may be multiple, such as GNSS positioning assistance data, or specific data of a GNSS positioning assistance data center, etc., which is not limited in the present disclosure.

[0198] In addition, the identifier of the positioning information can represent the uniqueness of the positioning information, that is, it can indicate whether it is positioning auxiliary information, a positioning pilot signal, or other positioning information, etc., which is not limited in the present disclosure.

[0199] It is understandable that there may be multiple ways to send positioning information, such as unicast, multicast, broadcast, etc., and the present disclosure does not limit this.

[0200] In addition, the duration of sending the positioning information may be any duration, such as 5 ms, 1.5 s, etc., and the present disclosure does not limit this.

[0201] It is understandable that the period for sending positioning information may also be set according to actual needs, such as sending once every 3 minutes, or once every 1 minute, etc., and the present disclosure does not limit this.

[0202] In addition, the resource index number corresponding to the positioning information may also be pre-set content, and the resources may be of various types, such as time domain, frequency domain, spatial domain, etc., which is not limited in the present disclosure.

[0203] It is understandable that the message name of the request may also be multiple, such as message 2, message A, message d, etc. Different message names correspond to different positioning information. For example, the message name is message 2, which may correspond to auxiliary information related to the positioning pilot signal sent by the NR-RAN node. Or the message name is message A, which may correspond to auxiliary information related to the positioning pilot signal sent on the Uu port. Or the message name is message d, which may correspond to auxiliary information related to the positioning pilot signal sent on the sidelink interface, etc., which is not limited in this disclosure.

[0204] In addition, the positioning request may include one message name in sequence, or may include multiple message names at one time, which is not limited in the present disclosure.

[0205] It is understandable that the positioning request may also be in the form of a signal, and each signal and the corresponding positioning information may be content agreed in advance between the first UE and the communication device. For example, when the positioning request is signal 1, it may correspond to GNSS-related auxiliary information, or, when the positioning request is signal 2, it may correspond to auxiliary information related to the positioning pilot signal sent by the NR-RAN node, and the present disclosure does not limit this.

[0206] In addition, the positioning information may be at least one of the following information: positioning auxiliary information and a positioning pilot signal.

[0207] The positioning assistance information may be information used to assist the communication device in performing positioning-related processes, such as informing the communication device to monitor the time domain / frequency domain position of the positioning pilot signal.

[0208] For example, the communication device needs to obtain GNSS-related auxiliary information and can send a GNSS-related positioning request to the first UE. Alternatively, it is agreed in advance that signal 1 corresponds to GNSS-related auxiliary information and signal 2 corresponds to auxiliary information related to the positioning pilot signal sent by the NR-RAN node, and the communication device can send signal 2 to the first UE.

[0209] It should be noted that the above examples are only illustrative and cannot be used as limitations on positioning requests, etc. in the embodiments of the present disclosure.

[0210] In the disclosed embodiment, the communication device sends a positioning request to the first UE, and the positioning request is used to instruct the first UE to send positioning information on the sidelink interface. Thus, the sidelink interface resources in the UE are saved and the efficiency of positioning on the sidelink interface is greatly improved.

[0211] The following takes the communication device as a base station as an example. Figure 6 The positioning method provided by the present disclosure is further described.

[0212] Step 601: Receive a positioning request sent by a second UE, and send a positioning request to a first UE.

[0213] After receiving the positioning request sent by the second UE, the base station can determine that there is a sidelink positioning requirement within a certain range of the current base station, and thus can send a positioning request to the first UE.

[0214] For example, the positioning request sent by the second UE may be "request to send positioning assistance information".

[0215] Optionally, the positioning request may carry the type of positioning assistance information requested to be sent, which may be one or more types, and the present disclosure does not limit this.

[0216] In addition, the positioning request may also be a request for the first UE to send GNSS positioning assistance data, or a request for the first UE to send a specific data in the GNSS positioning assistance data (such as GNSS reference time assistance data, GNSS earth position parameter assistance data). Or the positioning request may also be a request for the first UE to send auxiliary information related to the NR-RAN node sending the positioning pilot signal; or a request for auxiliary information related to the positioning pilot signal sent on the Uu interface; or a request for auxiliary information related to the positioning pilot signal sent on the sidelink interface, etc., which is not limited in this disclosure.

[0217] In addition, the positioning request may also include a message name of the request. It is understandable that different message names may correspond to different positioning information, and the positioning request may include one message name, or may also include multiple message names, which is not limited in the present disclosure.

[0218] For example, message 1 may include GNSS-related auxiliary information, message 2 may include auxiliary information related to the positioning pilot signal sent by the NR-RAN node, message 3 may be auxiliary information related to the positioning pilot signal sent on the Uu interface, and message 4 may be auxiliary information related to the positioning pilot signal sent on the sidelink interface. The positioning request sent by the base station to the first UE may be a request to send message 1, or the positioning request sent by the base station to the first UE may be a request to send message 1, message 2, and message 4, etc., which is not limited in this disclosure.

[0219] In addition, the positioning request may also include a sending method, which may be broadcast, multicast or a dedicated channel, etc., which is not limited in the present disclosure.

[0220] It is understandable that the positioning request may also include the resources used for sending, which may be in the time domain, frequency domain, and / or spatial domain, etc., and the present disclosure does not limit this.

[0221] In addition, the positioning request may also be a positioning pilot signal. For example, the base station obtains the positioning request sent by the second UE, which may be "requesting to send a positioning pilot signal on a sidelink interface".

[0222] Furthermore, the positioning request may carry an identifier of the positioning pilot signal requested to be sent. For example, if the identifier of the positioning pilot signal in the positioning request obtained by the base station is 1, the positioning request may be sent to the first UE.

[0223] It should be noted that the above-mentioned identifier 1 is only an example and cannot be used as a limitation on the identifier of the positioning pilot signal in the embodiment of the present disclosure.

[0224] In addition, the positioning request may also carry the type of positioning pilot signal requested to be sent. For example, one or more positioning pilot signals that can be sent on the sidelink interface may be defined. Among them, different positioning pilot signals can meet different application scenarios. For example, positioning pilot signal 1 is suitable for commercial indoor scenarios, positioning pilot signal 2 is suitable for industrial deployment scenarios, etc.

[0225] It should be noted that the content that can be carried in the positioning request can refer to the description of other embodiments of the present disclosure and will not be repeated here.

[0226] It can be understood that the positioning request may be a designated signal, and the designated signal corresponds to at least one of the following: the type of positioning information, the message containing the positioning information, and the resource corresponding to the positioning information.

[0227] For example, the designated signal may be request signal 1, which corresponds to GNSS reference time assistance data, or the designated signal may be request signal 2, which corresponds to GNSS reference position assistance data. Alternatively, the designated signal may be request signal 3, which corresponds to GNSS positioning assistance data, or the designated signal may be request signal 4, which corresponds to auxiliary information related to the positioning pilot signal sent by the NR-RAN node, etc., and the present disclosure does not limit this.

[0228] It should be noted that the positioning request is a specific description of a designated signal, and reference may be made to the descriptions of other embodiments of the present disclosure, which will not be repeated here.

[0229] In addition, when the communication device is a base station or a positioning server, the positioning request may also include positioning information.

[0230] It is understandable that the positioning information may be acquired and stored in advance by the first UE. Alternatively, it may be sent by the base station or the positioning server to the first UE in a positioning request. The base station or the positioning server may send the positioning information to the UE through one positioning request, or may send the positioning information to the UE through multiple positioning requests, which is not limited in the present disclosure.

[0231] It should be noted that the communication equipment base station in the embodiment of the present disclosure may also be replaced with an LMF, and the present disclosure does not limit this.

[0232] It is understandable that the base station may determine, based on its own algorithm, that there is a large demand for sidelink positioning at present, and may send a positioning request to the first UE. Alternatively, the base station may obtain a positioning request sent by a positioning server, determine that the first UE is currently required to send auxiliary positioning information, and thus may send a positioning request to the first UE. This disclosure does not limit this.

[0233] For example, the base station receives a positioning request from the positioning server, which is auxiliary data of GNSS earth position parameters in a broadcast format and is sent every 2 minutes. Then, the base station can send the positioning request to the first UE.

[0234] Alternatively, the base station obtains a positioning request sent by the positioning server, which may be auxiliary information related to the positioning pilot signal sent by the NR-RAN node, in broadcast form, and sent every 3 minutes. After that, the base station can send the positioning request to the first UE.

[0235] It should be noted that the above examples are only illustrative and cannot be used as limitations on the positioning request and the like in the embodiments of the present disclosure.

[0236] The embodiment of the present disclosure receives a positioning request sent by a second UE and sends a positioning request to a first UE, thereby saving sidelink interface resources in the UE and greatly improving the efficiency of positioning on the sidelink interface.

[0237] The following takes the communication device as UE as an example. Figure 7 The positioning method provided by the present disclosure is further explained.

[0238] Step 701: Obtain an indication message sent by the first UE on the sidelink interface, wherein the indication message is used to indicate information of a positioning signal that can be provided by the first UE.

[0239] Among them, the indication message may include at least one of the following information: whether to send positioning information on the sidelink interface, the type of positioning information sent on the sidelink interface, the name of the sending message associated with each positioning information, the corresponding resource index number of the positioning information sent on the sidelink interface, the corresponding resource of the positioning information sent on the sidelink interface, the sending method of the positioning information, the signal identifier associated with each positioning information, the name of the request message associated with each positioning information, the type of positioning information corresponding to each positioning request signal, the resource of the positioning information corresponding to each positioning request signal, and the resource index number of the positioning information corresponding to each positioning request signal.

[0240] It should be noted that, for the specific description of the indication message, reference can be made to the description of other embodiments of the present disclosure and will not be repeated here.

[0241] Step 702: Send a positioning request to the first UE, where the positioning request is used to instruct the first UE to send positioning information on the sidelink interface.

[0242] The positioning request may be a message, or a signal, etc., which is not limited in the present disclosure.

[0243] For example, the positioning request sent to the first UE may be a "request to send positioning assistance information".

[0244] Among them, the positioning request may be a signal. Further, the positioning request may be a request signal sent by the UE according to the corresponding relationship between the positioning request signal and the type of positioning assistance information or the message corresponding to the positioning assistance information, combined with its own needs. For example, if the UE expects to receive GNSS positioning assistance data, the UE can use request signal 1 to send a request to the first UE, and this disclosure does not limit this.

[0245] Or the positioning request may also be a message. Further, it may carry the type of positioning assistance information requested to be sent, which may be one or more. For example, the positioning request may be a request for the UE to send GNSS positioning assistance data, or the positioning request may be a request for the UE to send GNSS reference time assistance data, GNSS earth position parameter assistance data, etc. Or the positioning request may be a request for the UE to send auxiliary information related to the positioning pilot signal sent by the NR-RAN node. Or the positioning request may be a request for auxiliary information related to the positioning pilot signal sent on the Uu interface, or a request for auxiliary information related to the positioning pilot signal sent on the sidelink interface, etc., which is not limited in the present disclosure.

[0246] It is understandable that the positioning request may also include a sending method, such as broadcast, multicast, or unicast, etc., which is not limited in the present disclosure.

[0247] In addition, the positioning request may also include a sending duration, a sending cycle, etc., which is not limited in the present disclosure.

[0248] In addition, the UE may also send a positioning pilot signal to the first UE.

[0249] For example, if the UE has a sidelink positioning requirement, the UE may send a positioning request signal to the first UE. Further, the UE may determine the specific positioning request signal to be sent according to the required positioning pilot type and / or configuration, for example, if request signal 1 corresponds to positioning pilot signal 1 and the UE expects to receive positioning pilot signal 1, the UE may send request signal 1 to the first UE, and the present disclosure does not limit this.

[0250] Alternatively, the UE sends a positioning request of "requesting to send a positioning pilot signal on a sidelink interface" to the first UE.

[0251] Furthermore, the positioning request may carry one or more types of information. For example, the positioning request may carry the type of positioning pilot signal requested to be sent, for example, if the UE expects to receive positioning pilot signal 2 at this time, the first UE may be requested to send positioning pilot signal 2 on the sidelink interface.

[0252] Alternatively, the positioning request may also carry the beam direction of the positioning pilot signal requested to be sent. For example, the first UE sends the positioning pilot signal using beam scanning on the sidelink interface, and the UE can only monitor the positioning pilot signal sent by the first UE on the sidelink on a specific beam or certain beams. At this time, the UE can request the first UE to send the positioning pilot signal only on a specific beam or a specific set of beams, thereby reducing the overhead of sending the positioning pilot signal on the sidelink and also reducing the beams monitored by the UE.

[0253] Alternatively, the positioning request may also carry the resources used for sending, such as the time domain, frequency domain, and / or spatial domain, etc., which is not limited in the present disclosure.

[0254] Alternatively, the positioning request may also carry a sending duration, a sending cycle, an index number of a resource requested to be sent, etc., which is not limited in the present disclosure.

[0255] In the embodiment of the present disclosure, an indication message sent by the first UE on the sidelink interface is obtained, and the indication message is used to indicate information of a positioning signal that the first UE can provide, and then a positioning request can be sent to the first UE, and the positioning request is used to instruct the first UE to send positioning information on the sidelink interface. Thus, the sidelink interface resources in the UE are saved, and the efficiency of positioning on the sidelink interface is greatly improved.

[0256] Figure 8 It is a structural schematic diagram of a positioning device provided according to an embodiment of the present disclosure, wherein the positioning device is applied to user equipment.

[0257] like Figure 8 As shown, the positioning device may include a transceiver 800, a processor 810, and a memory 820, wherein:

[0258] The transceiver 800 is used to receive and send data under the control of the processor 810 .

[0259] Among them, Figure 8In the embodiment, the bus architecture may include any number of interconnected buses and bridges, specifically linking together various circuits of one or more processors represented by processor 810 and memory represented by memory 820. The bus architecture may also link together various other circuits such as peripherals, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein. The bus interface provides an interface. The transceiver 800 may be a plurality of components, namely, a transmitter and a receiver, providing a unit for communicating with various other devices on a transmission medium, including, these transmission media include wireless channels, wired channels, optical cables and other transmission media.

[0260] like Figure 8 As shown, the positioning device may also include a user interface 830. For different user devices, the user interface 830 may also be an interface capable of externally or internally connecting required devices.
