[0003] Currently, in 5G systems, location information can be transmitted to User Equipment (UE) via the 5G Radio Access Network (NG-RAN). However, in the Central Unit (CU)-Distributed Unit (DU) architecture of a 5G base station, the Central Unit (gNB-CU) typically obtains the location information from the Distributed Unit (gNB-DU) after the location information exchange, through a UE uplink message modification process. This increases location latency and adds additional signaling load. Summary of the Invention

[0004] This disclosure provides a method, apparatus, communication device, and storage medium for processing location configuration information.

[0005] According to a first aspect of this disclosure, a method for processing location configuration information is provided, executed by a gNB-DU, comprising:

[0006] Information related to the Sounding Reference Signal (SRS) configuration is sent to the gNB-CU so that the gNB-CU can send the SRS configuration-related information to the UE, wherein the SRS configuration-related information is used for the UE's positioning.

[0007] According to a second aspect of this disclosure, a method for processing location configuration information is provided, executed by a gNB-CU, comprising:

[0008] A method for processing location configuration information, wherein the method is executed by the base station central unit gNB-CU, includes:

[0009] Receive SRS configuration-related information sent by gNB-DU;

[0010] The SRS configuration-related information is sent to the UE, wherein the SRS configuration-related information is used for UE positioning.

[0011] According to a third aspect of this disclosure, a method for processing location configuration information is provided, executed by a UE, comprising:

[0012] Receive SRS configuration-related information sent by gNB-CU, wherein the SRS configuration-related information is obtained by gNB-CU from base station distribution unit gNB-DU;

[0013] The UE's location is determined based on information related to the SRS configuration.

[0014] According to a fourth aspect of this disclosure, a positioning configuration information processing apparatus is provided, applied to a gNB-DU, comprising:

[0015] The first transmitting module is configured to send SRS configuration-related information to the gNB-CU, so that the gNB-CU sends the SRS configuration-related information to the UE, wherein the SRS configuration-related information is used for the UE's positioning.

[0016] According to a fifth aspect of this disclosure, a positioning configuration information processing apparatus is provided, applied to a gNB-CU, comprising:

[0017] The second receiving module is configured to receive SRS configuration-related information sent by the gNB-DU;

[0018] The second transmitting module is configured to send SRS configuration-related information to the UE, wherein the SRS configuration-related information is used for UE positioning.

[0019] According to a sixth aspect of this disclosure, a positioning configuration information processing apparatus is provided, applied to a UE, comprising:

[0020] The third receiving module is configured to receive information related to the SRS configuration sent by the gNB-CU; wherein the information related to the SRS configuration is obtained by the gNB-CU from the base station distribution unit gNB-DU;

[0021] The second processing module is configured to determine the UE's location based on information related to the SRS configuration.

[0022] According to a seventh aspect of this disclosure, a communication device is provided, comprising:

[0023] processor;

[0024] Memory used to store processor-executable instructions;

[0025] The processor is configured to implement the positioning configuration information processing method of any embodiment of this disclosure when executing executable instructions.

[0026] According to an eighth aspect of this disclosure, a computer storage medium is provided, which stores a computer-executable program that, when executed by a processor, implements the positioning configuration information processing method of any embodiment of this disclosure.

[0027] The technical solutions provided in this disclosure may have the following beneficial effects:

[0028] This embodiment of the present disclosure can send SRS configuration-related information from the gNB-DU to the gNB-CU, so that the gNB-CU can send the SRS configuration-related information to the UE. This SRS configuration-related information is used for UE positioning. This ensures that the gNB-CU sends the SRS configuration-related information to the UE, enabling the UE to perform positioning based on the SRS configuration-related information. Compared to the operation of obtaining positioning-related information from the gNB-DU through the gNB-CU based on the UE context modification process after positioning information exchange and then sending it to the UE, this embodiment of the present disclosure only requires the gNB-CU to directly send the SRS configuration-related information determined by the gNB-DU to the UE, enabling the UE to achieve positioning. This reduces positioning latency and signaling interaction, thereby saving power consumption of communication equipment (e.g., gNB-DU, gNB-CU, and / or UE), and also reduces additional signaling overhead.

Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 130 is not limited in this embodiment.

[0055] To facilitate understanding by those skilled in the art, this disclosure provides multiple embodiments to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0056] To better understand the technical solutions described in any embodiment of this disclosure, firstly, some aspects of the positioning-related technologies will be explained:

[0057] In one embodiment, location of UEs in the Radio Resource Control Inactive (RRC_Inactive) state is supported in R17. For example... Figure 2 As shown, the uplink positioning process for this RRC_Inactive UE includes the following steps.

[0058] Step S201: The communication device executes the delayed 5GC-MT-LR procedure for periodic or triggered positioning events in steps 1-21 of Clause 6.3.1 of TS 23.273 in the protocol;

[0059] Here, the communication equipment includes at least one of the following: UE, NG-RA, Access and Mobility Management Function (AMF), and Positioning Management Function (LMF).

[0060] Step S202: The UE determines that it is in the RRC_Inactive state;

[0061] Step S203: The UE detects an event;

[0062] Step S204: The UE sends an event report of uplink NAS transmission, including RRC recovery request and UL information transmission;

[0063] Step S205: NG-RAN sends an LCS event report;

[0064] Step S206: The LMF sends a location information request message;

[0065] Step S207: gNB in ​​NG-RAN determines UL-SRS resources;

[0066] Step S208: NG-RAN sends a location response message;

[0067] Step S209: LMF sends an NRPPa measurement request;

[0068] Step S210: The LMF sends confirmation information for the LCS event report;

[0069] Step S211: NG-RAN sends event report confirmation information via DL SDT;

[0070] Step S212: NG-RAN sends RRC signaling carrying UL-SRS configuration information;

[0071] Step S213: NG-RAN performs UE positioning measurements based on UL-SRS configuration information;

[0072] Step S214: NG-RAN sends NRPPa measurement response;

[0073] Step S215: Execute the delayed 5GC-MT-LR procedure for periodic or triggered location events in Steps 28-31 of Clause 6.3.1 of TS 23.273 in the protocol.

[0074] In the above embodiment, in step S206, NG-RAN can generate the positioning configuration information in the RRC_Inactive state, such as the SRS configuration-related information in the RRC_Inactive state; and send it to the UE through step S210.

[0075] If the NG-RAN is a CU-DU separated architecture, the SRS configuration-related information should be generated by the gNB-DU, while the gNB-CU is ultimately responsible for sending the SRS configuration-related information to the RRC_Inactive UE. Therefore, the gNB-DU needs to send the SRS configuration-related information to the gNB-CU. In this embodiment, the SRS-related configuration information includes SRS configuration information and specific configuration information added in the RRC_Inactive state.

[0076] like Figure 3 As shown, this embodiment of the disclosure provides a location configuration information processing method, executed by a gNB-DU, including:

[0077] Step S31: Send SRS configuration-related information to gNB-CU so that gNB-CU sends SRS configuration-related information to UE, wherein the SRS configuration-related information is used for UE positioning.

[0078] The gNB-DU and gNB-CU involved in the embodiments of this disclosure can be distributed units or central units of other base stations; the base station can be, but is not limited to, various types of base stations; for example, it can be a 2G base station, a 3G base station, a 4G base station, a 5G base station, or other evolved base stations; as long as the base station has a CU-DU architecture. Here, the gNB-DU and gNB-CU can be deployed together or separately.

[0079] In some embodiments, step S31 may include sending SRS configuration-related information to the gNB-CU in response to determining that the UE is in an RRC inactive state or an RRC idle state, so that the gNB-CU sends the SRS configuration-related information to the UE; the SRS configuration-related information is used for the UE's positioning.

[0080] Sending SRS configuration-related information to the gNB-CU can be done spontaneously by the gNB-DU when certain conditions are met, or it can be done based on a received request, the latter of which will be described later.

[0081] The gNB-DU and gNB-CU involved in the embodiments of this disclosure can be replaced by a first network node and a second network node. The first network node and the second network node can be network elements or functions of the access network or core network. The first network node and the second network node can be logical nodes that are flexibly deployed in the communication network, and there are no restrictions here.

[0082] The UE involved in the embodiments of this disclosure can be various mobile terminals or fixed terminals. For example, the UE can be, but is not limited to, a mobile phone, a computer, a server, a wearable device, a vehicle terminal, a roadside unit (RSU), a game control platform, or a multimedia device.

[0083] In some embodiments, the UE can be an RRC-inactive UE and / or an RRC-connected UE; wherein, the inactive UE includes: an RRC-inactive UE and / or an RRC-idle UE.

[0084] The SRS configuration-related information in this embodiment can also be location configuration-related information. Here, location configuration-related information can be, but is not limited to, SRS configuration-related information. This location configuration-related information can also be information related to other signal configurations, as long as it can be used for UE positioning; no limitations are placed on the location configuration-related information.

[0085] For example, this disclosure provides a location configuration information processing method, executed by a gNB-DU, including:

[0086] The location configuration information is sent to the gNB-CU base station. This location configuration information is used by the gNB-CU to send the location configuration information to the UE for the UE's location.

[0087] In some embodiments, information related to SRS configuration is used for UE location in RRC inactive state or RRC idle state.

[0088] This disclosure provides a location configuration information processing method, executed by a gNB-DU, including:

[0089] Information related to SRS configuration is sent to the base station gNB-CU so that gNB-CU can send the information related to SRS configuration to the UE. The information related to SRS configuration is used for UE positioning in RRC inactive state or RRC idle state.

[0090] Thus, in this embodiment of the disclosure, the gNB-DU can send information related to SRS configuration to the RRC-unconnected UE (such as an RRC-inactive UE or an RRC-idle UE) via the gNB-CU, so that the RRC-unconnected UE can achieve positioning.

[0091] Here, information related to SRS configuration can be used for UE location, which includes, but is not limited to, at least one of the following operations: determining SRS transmission, determining SRS release, and / or determining the method of transmitting SRS. Here, determining SRS transmission includes at least determining when to transmit SRS; determining SRS release includes at least determining when to release SRS.

[0092] In some embodiments, the information related to SRS configuration includes at least one of the following:

[0093] The first type of configuration information used for UE positioning in RRC inactive state or RRC idle state includes at least one of the following: time and frequency resources and period information;

[0094] The second type of configuration information for UE positioning in the RRC inactive state or RRC idle state includes at least one of the following: Part bandwidth (BWP) information; Reference Signal Receiving Power (RSRP) threshold information for Time Alignment (TA) verification; Downlink path loss reference information for TA verification; Absolute RSRP threshold information of the Synchronization Signal Block (SSB) set for downlink path loss reference for TA verification; and TA timing information indicating SRS positioning transmission.

[0095] In some embodiments, BWP information includes: Supplementary Uplink Part bandwidth (BWP-SUL); and / or Normal Uplink Part bandwidth (BWP-NUL).

[0096] In some embodiments, the RSRP threshold information includes at least one of the following:

[0097] A second indication message indicating an increase in the RSRP threshold;

[0098] The third indication information indicates a reduction in the RSRP threshold.

[0099] Here, the second type of configuration information can be used to indicate the time for sending information related to SRS configuration and / or the time for releasing information related to SRS configuration.

[0100] For example, the first type of configuration information could be: srs-PosRRCInactiveConfig.

[0101] For example, RSRP threshold information could be: inactivePosSRS-RSRP-changeThresh.

[0102] For example, downlink path loss reference information could be: inactivePosSRS-NrofSS-BlocksToAverage.

[0103] For example, the absolute RSRP threshold information of the set of Synchronization Signal Blocks (SSBs) for downlink path loss reference can be: inactivePosSRS-AbsThreshSS-BlocksConsolidation.

[0104] For example, the TA timing information can be: TA timer. For instance, the TA timing information can be: srs-TimeAlignmentTimer.

[0105] Of course, in other embodiments, the first type of configuration information can be other location configuration information; and / or the second type of configuration information can also be other location configuration information. For example, in some embodiments, the first type of configuration information can be existing SRS configuration-related information in R17; the second type of configuration information can be newly added SRS configuration-related information.

[0106] This embodiment of the present disclosure can send SRS configuration-related information from the gNB-DU to the gNB-CU, so that the gNB-CU can send the SRS configuration-related information to the UE. This SRS configuration-related information is used for UE positioning. This ensures that the gNB-CU sends the SRS configuration-related information to the UE, enabling the UE to perform positioning based on the SRS configuration-related information. Compared to the operation of obtaining positioning-related information from the gNB-DU through the gNB-CU based on the UE context modification process after positioning information exchange and then sending it to the UE, this embodiment of the present disclosure only requires the gNB-CU to directly send the SRS configuration-related information determined by the gNB-DU to the UE, enabling the UE to achieve positioning. This reduces positioning latency and signaling interaction, thereby saving power consumption of communication equipment (e.g., gNB-DU, gNB-CU, and / or UE), and also reduces additional signaling overhead.

[0107] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0108] In some embodiments, sending information related to the detection reference signal (SRS) configuration to the base station central unit gNB-CU in step 31 includes sending a positioning information response message carrying information related to the SRS configuration to the gNB-CU.

[0109] This disclosure provides a location configuration information processing method, executed by a gNB-DU, including: sending a location information response message carrying information related to SRS configuration to a gNB-CU.

[0110] For example, the location information response message could be a Positioning Information Response.

[0111] That is, the base station central unit gNB-DU informs gNB-CU of the SRS configuration-related information by sending a location information response message carrying SRS configuration-related information to gNB-CU. Then gNB-CU can forward the information to UE so that UE can achieve positioning.

[0112] Thus, in this embodiment of the disclosure, information related to SRS configuration can be carried in the location information response message, which can further reduce signaling interaction.

[0113] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0114] like Figure 4 As shown, this embodiment of the disclosure provides a location configuration information processing method, executed by a gNB-DU, including:

[0115] Step S41: Receive a location information request message sent by gNB-CU, wherein the location information request message is used to request information related to SRS configuration.

[0116] In some embodiments of this disclosure, the information related to SRS configuration may be the information related to SRS configuration in step S31, which will not be repeated here.

[0117] For example, a location information request message could be a Positioning Information Request.

[0118] In one embodiment, the location information request message is used to request location configuration-related information. Thus, it can request location configuration-related information for positioning using SRS or other signals.

[0119] That is, the gNB-DU can send SRS configuration-related information to the gNB-CU upon request from the gNB-CU. However, it should be understood that the gNB-DU can also send SRS configuration-related information to the gNB-CU on its own when certain conditions are met. For example, when the gNB-DU confirms that the UE is in an inactive state (e.g., the UE has an ongoing SDT procedure), the gNB-DU can send SRS configuration-related information to the gNB-CU.

[0120] In one embodiment, the location information request message is used to request SRS configuration-related information for a UE in an RRC inactive state and / or an RRC idle state. Thus, SRS configuration-related information can be requested from a UE in an RRC inactive state and / or an RRC idle state.

[0121] In some embodiments, the location information response message is determined based on the location information request message.

[0122] In some embodiments, before step S31, the method includes: receiving a location information request message sent by the gNB-CU, wherein the location information request message is used to request information related to SRS configuration.

[0123] This disclosure provides a location configuration information processing method, executed by a gNB-DU, including:

[0124] Receive a location information request message sent by gNB-CU, wherein the location information request message is used to request information related to SRS configuration;

[0125] Send SRS configuration related information to gNB-CU.

[0126] Thus, in this embodiment of the disclosure, a request message can be sent from the gNB-CU to the gNB-DU to request the configuration information related to the SRS configuration required by the UE.

[0127] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0128] In some embodiments, sending SRS configuration-related information to the gNB-CU in step 31 includes:

[0129] In response to the received location information request message carrying first indication information, information related to SRS configuration is sent to the gNB-CU; wherein, the first indication information is used to indicate the SRS configuration related information of the UE that is in RRC inactive state or RRC idle state.

[0130] like Figure 5 As shown, this embodiment of the disclosure provides a location configuration information processing method, executed by a gNB-DU, including:

[0131] Step S51: In response to the received location information request message carrying first indication information, send information related to SRS configuration to gNB-CU; wherein, the first indication information is used to indicate the SRS configuration related information of the UE that is in RRC inactive state or RRC idle state.

[0132] In some embodiments of this disclosure, the information related to SRS configuration may be the information related to SRS configuration in step S31.

[0133] Here, the information related to SRS configuration is used to locate UEs in RRC active state or RRC idle state.

[0134] Thus, in this embodiment of the disclosure, when the location information request message received by the gNB-DU includes an indication that a UE is requesting an RRC inactive state or an RRC idle state, the gNB-DU sends SRS configuration-related information to the UE in the RRC active state or the RRC idle state, so that the UE in the RRC active state or the RRC idle state can achieve location. Here, this embodiment of the disclosure can use the direct indication in the location information request message to cause the gNB-DU to send SRS configuration-related information for the UE in the RRC inactive state or the RRC idle state.

[0135] In some embodiments, in step S31, the gNB-CU sends information related to the SRS configuration, including:

[0136] In response to determining that the UE is in an RRC inactive state or an RRC idle state, information related to SRS configuration is sent to the gNB-CU.

[0137] This disclosure provides a location configuration information processing method, executed by a gNB-DU, including: in response to determining that the UE is in an RRC inactive state or an RRC idle state, sending information related to SRS configuration to the gNB-CU.

[0138] This disclosure provides a location configuration information processing method, executed by a gNB-DU, including: in response to receiving a location information request message and determining that the UE is in an RRC inactive state or an RRC idle state, sending information related to SRS configuration to the gNB-CU.

[0139] Here, the location information request message may not include the first indication information. In this case, the location information request message is used to request information related to SRS configuration, which can be adapted to any state of the UE; for example, it can be adapted to a UE in RRC inactive state, a UE in RRC idle state, or a UE in RRC connected state.

[0140] Thus, in this embodiment of the disclosure, when the gNB-DU determines that the UE is in an RRC inactive state or an RRC idle state, it sends SRS configuration-related information for the UE in the RRC inactive state or an RRC idle state to the gNB-CU. This allows for the use of better bits in the location information request message, enabling the message to carry more additional bits for other operational information.

[0141] This disclosure provides a location configuration information processing method, executed by gNB-DU, including: determining that the UE is in an RRC inactive state based on the UE being in a Small Data Transmission (SDT) process.

[0142] Of course, in other embodiments, it is possible to determine whether the UE is in an RRC inactive state or an RRC idle state in any feasible manner.

[0143] In this embodiment of the disclosure, it is possible to accurately determine whether the UE is in the RRC inactive state by determining whether the UE is in the SDT process.

[0144] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0145] The following location configuration information processing method is executed by gNB-CU, and is similar to the location configuration information processing method executed by gNB-DU described above; and for technical details not disclosed in the embodiments of the location configuration information processing method executed by gNB-CU, please refer to the description of the example of the location configuration information processing method executed by gNB-DU, which will not be described in detail here.

[0146] like Figure 6 As shown, this embodiment of the disclosure provides a location configuration information processing method, executed by gNB-CU, including:

[0147] Step S61: Receive SRS configuration-related information sent by gNB-DU;
