[0013] In an embodiment of the present application, the LMF sends down a configuration carrying multiple sets of PRS configurations, and a base station or a TPR has multiple sets of alternative PRS configurations. In this way, when positioning the UE, a PRS configuration that meets the current positioning requirements can be selected to ensure that the positioning requirements are met while minimizing the signaling overhead.

[0036] The base station 12 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system.

[0037] Among them, the base station 12 can be an evolved base station (eNB) adopted in the 4G system. Alternatively, the base station 12 can also be a base station (gNB) adopting a centralized distributed architecture in the 5G system. When the base station 12 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU).

The implementation form of the network management device 13 is not limited in the embodiments of the present disclosure.

[0042] Figure 2A As shown, LMF exchanges various information of PRS positioning with base stations (including but not limited to gNB) through NRPPa messages specified by the NRPPa protocol, for example, including but not limited to PRS configuration. Figure 2A In the process, LMF requests a DL-TDOA request from gNB, which also includes the PRS configuration recommended by LMF. After receiving the request, gNB sends a DL-TDOA response to LMF, which also includes the PRS configuration information of the base station. At the same time, the base station sends PRS according to the PRS configuration information.

[0043] Figure 2B As shown, the LMF directly interacts with the UE through the LPP message specified by the LPP protocol through the transparent transmission of the base station for various information of PRS positioning, for example, including but not limited to PRS configuration.

[0044] 5G R16 introduces a variety of positioning technologies to achieve UE positioning. For some of these positioning technologies, the network needs to provide positioning assistance information to the UE, such as Figure 2C As shown, LMF provides positioning assistance information to UE through LPP message. In addition, LMF can also send positioning assistance information to the base station through NRPPa message, and then the base station sends it to UE through system message, such as Figure 2C As shown, it may include:

[0045] 1.LMF sends NRPPa positioning assistance message (NRPPa AssitanceInformation Control) to the base station and other wireless network access nodes, for example, Figure 2CThe next generation radio access network (NG-RAN) node (Node) wireless network access node such as the 5G base station shown;

[0046] 2. The NG-RAN node sends RRC System Information to the UE;

[0047] 3. LMF sends a broadcast key notification (Nlmf_Broadcast_CipheringKeyData Notify (Ciphering Keys)) to the Access Management Function (AMF). The Ciphering Keys are keys used to encrypt information broadcast by the base station.

[0048] 4. The NG-RAN node sends an NRPPa message feedback (Assistance Information Feedback) to the LMF to feedback whether the information sent by the LMF is correctly received. However, this step is an optional step.

[0049] 5.LMF sends NRPPa positioning assistance message (NRPPa AssitanceInformation Control) to base stations and other wireless network access nodes.

[0050] 6. Send RRC System Information.

[0051] 7.LMF sends NRPPa positioning assistance message (NRPPa AssitanceInformation Control) to base stations and other wireless network access nodes.

[0052] In related technologies, the PRS configuration of R16 is static configuration. However, considering the positioning accuracy requirements of UE and system overhead, dynamic PRS configuration can reduce system overhead while meeting high-precision positioning requirements. Therefore, it is necessary to implement dynamic positioning broadcast auxiliary information.

[0053] like Figure 3A As shown, an embodiment of the present application provides a positioning reference signal PRS configuration processing method, which is applied to a positioning management function LMF, including:

[0054] S110: Send down first configuration information carrying multiple sets of PRS configurations, where the multiple sets of PRS configurations correspond to one base station or one TRP; the PRS configurations are used for positioning measurement of user equipment UE.

[0055] In this way, a base station can have multiple sets of alternative TPS configurations; or, a TRP has multiple sets of alternative TPS configurations.

[0056] The first configuration information can be sent from LMF to the base station or TPR, or it can be transparently transmitted to the UE through the base station or TRP. If sent to the base station or TPR, the first configuration information can be carried through the NRPPa message. If the LMF is sent directly to the UE, the first configuration information is carried through the LPP message.

[0057] The PRS configuration may include at least one of the following:

[0058] PRS resource configuration is used to indicate the resource location of the positioning reference signal.

[0059] The PRS measurement mode configuration is used for measuring the PRS, including but not limited to: at least one of a downlink-time difference of arrival (DL-TDOA), an uplink-time difference of arrival (UL-TDOA), a downlink-angle of arrival (DL-AOA), and an enhanced cell identity positioning method (E-CID);

[0060] Measurement parameter configuration, including but not limited to: Position Reference Signals-Reference Signal Receiving Power (PRS-RSRP) and Position Reference Signals-Reference Signal Time Difference (PRS-RSTD);

[0061] The positioning service quality requirement configuration includes but is not limited to: positioning accuracy and / or positioning delay.

[0062] By sending multiple sets of PRS configurations at the same time, you can select the PRS configuration that meets the current positioning requirements during positioning, ensuring that the positioning requirements are met while minimizing signaling overhead.

[0063] In some embodiments, different sets of PRS configurations satisfy different positioning accuracies; and / or different sets of PRS configurations require different positioning overheads.

[0064] Due to the multiple PRS configurations, the base station and the UE can select a PRS configuration suitable for the current positioning requirement when performing positioning measurements.

[0065] The positioning accuracy is determined by the positioning distance, and the positioning accuracy includes: some positioning accuracy requires positioning to the 10-meter level, some positioning accuracy requires positioning to the meter level, and some positioning accuracy requires positioning to the decimeter or centimeter level.

[0066] The positioning accuracy is determined by the signal quality of the PRS, and the positioning accuracy may include: the accuracy of the received power or received quality of the PRS needs to be at a decibel level or a 0.1 decibel level, etc.

[0067] Location costs include but are not limited to:

[0068] Resource overhead, for example, the overhead of time-frequency resources for sending and receiving PRS;

[0069] Signaling overhead: signaling overhead occurs in the process of sending and receiving PRS and reporting positioning results;

[0070] Power overhead, for example, if the power of transmitting PRS is large, the power consumption overhead is large.

[0071] For example, different sets of PRS configurations may differ in at least one of the following:

[0072] PRS sending cycle;

[0073] The transmission bandwidth of PRS;

[0074] The sending resources of PRS.

[0075] The larger the transmission period, the longer the time interval between two adjacent PRS transmissions.

[0076] The larger the transmission bandwidth of the PRS is, the larger the resources occupied in the frequency domain for sending the PRS once are.

[0077] The transmission resources of the PRS include but are not limited to time domain resources and / or frequency domain resources.

[0078] For example, for the measurement accuracy of positioning measurement, the more times or resources of PRS may be sent. If the signaling overhead is to be reduced, the fewer times or resources of PRS may be sent. In short, a set of PRS configurations can be selected from multiple sets of spare PRS configurations for positioning measurement according to the positioning requirements of this positioning or the current period.

[0079] When performing positioning measurement, the base station sends a PRS; the UE receives the PRS; and the UE realizes positioning of the UE based on the reception result of the PRS.

[0080] In some embodiments, sending first configuration information carrying multiple sets of PRS configurations includes: sending a broadcast assistance message carrying the first configuration information to a base station or a transceiver point TPR; and / or sending a positioning assistance message carrying the first configuration information to a user equipment UE.

[0081] The LMF may indicate to the base station or the TPR or the UE which set of PRS configurations is used for the current positioning according to the positioning requirements of the UE to be currently positioned and the positioning requirements that can be met by each set of PRS configurations in the multiple sets of PRS configurations currently issued. For example, the method further includes: issuing first indication information, wherein the first indication information indicates that a PRS configuration for positioning is selected from the multiple sets of PRS configurations.

[0082] For example, if the first indication information is sent via an LPP message, the first indication information is used to instruct the UE to select a set of PRS configurations from multiple sets of PRS configurations for positioning measurement. If the first indication information is sent via an NRPPa message, the first indication information is used to instruct the base station or TPR to select a set of PRS configurations from multiple sets of PRS configurations for positioning measurement.

[0083] At this time, in one embodiment, sending the first indication information includes: sending the first indication information to the base station or TRP by broadcasting an auxiliary message.

[0084] In another embodiment, the first indication information is sent to the user equipment UE via a positioning request message, wherein the positioning request message also carries a triggering instruction for triggering UE positioning.

[0085] In some other embodiments, LMF sends the first indication information to the base station or TPR, and may also send the first indication information to the UE at the same time, and the first indication information sent to the base station or TPR is carried by the NRPPa message, while the first indication information to the UE is carried by the LPP message.

[0086] In some embodiments, the method further comprises:

[0087] The second configuration information carrying the reconfiguration is sent down; the second configuration information includes: at least one set of updated PRS configuration, or, second indication information; the second indication information indicates at least one set of PRS configuration to be updated.

[0088] If the second configuration information can directly carry the updated PRS configuration, then after receiving the PRS configuration, the base station can directly use the PRS configuration in the second configuration information to replace the PRS configuration to be updated (ie, invalid).

[0089] In some embodiments, the second configuration information may be referred to as reconfiguration information.

[0090] If the second configuration information only carries the second indication information, the second indication information may indicate how to update one or more sets of PRS configurations previously configured according to the first configuration information. For example, the second indication information carries the offset of the PRS configuration before and after the update. For example, for PRS configuration 1, the period before the update is A; after the update is B; at this time, the second indication information may carry the offset of B relative to A.

[0091] The method further includes: sending a broadcast assistance message carrying the second configuration information to the base station or the transceiver point TPR.

[0092] The second configuration information may also be sent via a broadcast assistance message. In this way, the base station or TPR may receive the broadcast assistance information via an NRPPa message between the base station or TPR and the LMF.

[0093] For example, the method further includes:

[0094] Receive confirmation information of the second configuration information, wherein the confirmation information is used to indicate that the second configuration information is received.

[0095] Receiving a confirmation message of the second configuration information includes: receiving an NRPPa message carrying confirmation information sent by a base station or TRP.

[0096] The base station or TRP informs the LMF that the second configuration information has been received by sending a confirmation message, or that the received second configuration information has updated the PRS configuration in the base station.

[0097] In some embodiments, the method further comprises:

[0098] Receive third indication information reported by the base station or TRP, wherein the third indication information indicates the PRS configuration selected by the base station or TPR for positioning from multiple sets of PRS configurations.

[0099] The base station or TRP can compare the load or impact on the wireless environment of each set of PRS configurations for positioning measurement based on its current load and / or wireless environment, and can select one or more sets of PRS configurations suitable for the current load condition and / or wireless environment as the recommended PRS configuration, and then report the third indication information to the LMF. After receiving the third indication information, the LMF can determine a set of PRS configurations for current positioning based on the third indication information. The current positioning here includes but is not limited to: this positioning and / or one or more sub-positionings within the current time period. For example, the LMF can send a first indication information to the base station based on the third indication information, and the PRS configuration for positioning indicated in the first indication information may be the same as one or more sets of PRS configurations indicated by the third indication information, or may be different.

[0100] For example, receiving the third indication information reported by the base station or the TRP includes:

[0101] When the first indication information is not sent, the third indication information is received from the base station or TRP; the first indication information is sent by the LMF and is used to indicate the PRS configuration selected from multiple sets of PRS configurations for positioning.

[0102] For example, if the LMF does not have a clear demand for positioning at present, it may not send the first indication information, or it may receive the third indication information sent by the base station or TPR before sending the first indication information. Subsequently, the LMF may send the first indication information according to the third indication information. Alternatively, when the LMF agrees with the PRS configuration recommended by the base station for positioning, it may inform the base station by sending feedback information.

[0103] For example, the feedback information may be confirmation information, where the confirmation information is used to indicate that the PRS configuration recommended by the base station or the TPR is agreed to for positioning.

[0104] For another example, the feedback information may be a denial message, which indicates that the LMF disagrees with the PRS configuration suggested by the base station or TPR through the third indication message. In this case, the LMF may continue to issue the first indication message to specifically indicate the PRS configuration that the LMF wants the base station or TPR to use.

[0105] refer to Figure 3B As shown, this embodiment provides a PRS configuration processing method, including:

[0106] S210: Send an NRPPa message to a base station or a TPR, the NRPPa message carrying first configuration information of multiple sets of PRS configurations, and the multiple sets of PRS configurations are configurations of the same base station; or the multiple sets of PRS configurations are configurations of the same TPR.

[0107] Different sets of PRS configurations satisfy different positioning accuracies; and / or different sets of PRS configurations require different positioning overheads.

[0108] Different sets of PRS configurations differ in at least one of the following: a transmission period of the PRS; a transmission bandwidth of the PRS; and a transmission resource of the PRS.

[0109] In some embodiments, the NRPPa message received by the base station or TRP may carry first indication information in addition to the first configuration information. The first indication information indicates to the base station or TRP the PRS configuration used for the current positioning among the multiple PRS configurations.

[0110] Of course, in some embodiments, the first indication information and the first configuration information can be sent in the same NRPPa message to reduce the number of interactions between the LMF and the base station or the LMF and the TRP.

[0111] In some embodiments, the first indication information and the first configuration information may be sent in different NRPPa messages.

[0112] For example, if the LMF has not determined the first indication information when sending the first configuration information, the first configuration information and the first indication information are sent respectively through two NRPPa messages.

[0113] like Figure 3B As shown, in some embodiments, the method further includes:

[0114] S220: Send an NRPPa message carrying second configuration information; the second configuration information includes: at least one set of updated PRS configuration, or, second indication information; the second indication information indicates at least one set of PRS configuration to be updated.

[0115] In some embodiments, Figure 3B As shown, the method also includes:

[0116] S230: Receive confirmation information of the second configuration information, wherein the confirmation information is used to indicate that the second configuration information is received.

[0117] In some embodiments, Figure 3B As shown, the method also includes:

[0118] S240: When the first indication information is not sent, receiving third indication information from the base station or TRP; the first indication information is sent by the LMF and is used to indicate the PRS configuration selected from the set of PRS configurations for positioning.

[0119] like Figure 3C As shown, this embodiment provides a PRS configuration processing method, including:

[0120] S310: Send positioning assistance information to the UE, wherein the positioning assistance information is carried by an LPP message, and the positioning assistance information carries first configuration information of multiple sets of PRS configurations, and the multiple sets of PRS configurations correspond to one base station or one TRP; the PRS configuration is used for positioning measurement of the user equipment UE.

[0121] The LPP message here is transparently transmitted by the LMF to the UE through the base station.

[0122] In some embodiments, the positioning assistance information includes a cell identifier for positioning measurement and / or a base station identifier for positioning measurement; and resource location information of a positioning reference signal for positioning measurement.

[0123] In some embodiments, the cell identifier may be: an identifier of the last serving cell or a neighboring cell of the last serving cell.

[0124] In some other embodiments, the base station identifier may be: the identifier of the base station of the serving cell where the UE last stayed, or the identifier of the base station of the neighboring cell of the serving cell where the UE last stayed.

[0125] Through the cell identifier and / or base station identifier, the UE can know the measurement object. When performing positioning measurement, the PRS sent by the cell or base station is measured. Therefore, when performing positioning measurement, the UE needs to know the resource location information of the PRS. The resource location information indicates the time-frequency resources sent by the PRS.

[0126] Different sets of PRS configurations satisfy different positioning accuracies; and / or different sets of PRS configurations require different positioning overheads.

[0127] For example, different sets of PRS configurations differ in at least one of the following: a transmission period of the PRS; a transmission bandwidth of the PRS; and a transmission resource of the PRS.

[0128] In some embodiments, Figure 3C As shown, the method also includes:

[0129] S320: Send first indication information to the user equipment UE via a positioning request message. The positioning request message is a type of LPP message, and is originally used to instruct the UE to perform positioning measurement.

[0130] For example, after the UE receives the positioning request message, it will perform positioning measurements according to the PRS configuration and report the positioning results. In an embodiment of the present application, since the UE receives multiple sets of PRS configurations of a base station or a TRP from the LMF, the positioning request message also carries a first indication information indicating which PRS configuration is used for the current positioning. In this way, the positioning request message will not only trigger the UE to perform positioning measurements, but also inform the UE based on which set of PRS configurations to perform positioning measurements.

[0131] For example, UE positioning measurements include but are not limited to:

[0132] The UE receives the PSR sent by the base station or TPR on the corresponding time-frequency resources according to the PRS configuration indicated by the first indication information.

[0133] like Figure 4A As shown, an embodiment of the present disclosure provides a method for processing first configuration information of a positioning reference signal PRS, which includes:

[0134] S410: Receive first configuration information carrying multiple sets of PRS configurations, where the multiple sets of PRS configurations correspond to one base station or one TRP; the PRS configurations are used for positioning measurement of a user equipment UE.

[0135] The LMF will send down the first configuration information carrying multiple sets of PRS configurations, so that the base station or TPR or UE will receive multiple sets of PRS configurations from the same base station or TPR.

[0136] In some embodiments, the method further comprises:

[0137] S420: Receive first indication information, where the first indication information is used to indicate selection of a PRS configuration for positioning from a plurality of PRS configurations.

[0138] Multiple sets of PRS configurations are received, wherein different sets of PRS configurations satisfy different positioning accuracies; and / or different sets of PRS configurations require different positioning overheads.

[0139] The differences between the multiple sets of PRS configurations include, but are not limited to: different sets of PRS configurations differ in at least one of the following: a PRS transmission period; a PRS transmission bandwidth; a PRS transmission resource.

[0140] The direct communication between LMF and base station or TPR may comply with the NRPPa protocol, while the communication between LMF and UE complies with the LPP protocol. Therefore, the following distinguishes the different receiving entities corresponding to the two protocols and gives examples.

[0141] like Figure 4B As shown, the embodiment of the present application provides a positioning reference signal PRS configuration processing method applied to a base station or a transceiver node TRP, including:

[0142] S510: Receive a broadcast assistance message carrying first configuration information, wherein the first configuration information carries multiple sets of PRS configurations. Multiple sets of PRS configurations in the multiple sets of PRS configurations belong to the same base station or the same TRP. For example, the first configuration information has M sets of PRS configurations, wherein N1 sets belong to base station 1 and N2 sets belong to base station 2. Both N1 and N2 are positive integers equal to or greater than 2. Multiple sets of PRS configurations of different base stations or TPRs may be partially identical or securely identical.

[0143] For example, if a total of S wireless network access nodes including the base station and the TPR receive the NRPPa message, the NRPPa message carries the first configuration information of M sets of PRS configurations, and the M sets belong to each wireless network access node, and each base station or TPR has M sets of PRS configurations. Of course, it is also possible that multiple sets of the M sets belong to some of the wireless network access nodes, and other multiple sets belong to the remaining wireless network access nodes.

[0144] In short, the first configuration information carried in the broadcast assistance message sent by LMF to the base station or TRP may include: multiple sets of PRS configurations for a base station, or multiple sets of PRS configurations for a TPR. In this way, the first configuration information carried in the broadcast assistance message received by a single base station or a single TRP may be multiple sets of PRS configurations configured by LMF for itself.

[0145] Different sets of PRS configurations have different positioning accuracy and / or different positioning overhead. When the base station cooperates with the UE to perform positioning measurement of the UE, it can select a PRS configuration suitable for the current positioning measurement from multiple sets of PRS configurations according to the accuracy requirements and / or overhead restrictions of the current UE positioning measurement, so as to meet the positioning requirements of different positioning measurements and improve the quality of service (QoS) of the positioning measurement.

[0146] like Figure 4B As shown, the method also includes:

[0147] S520: In response to the broadcast assistance message not carrying the first indication information, select a set of PRS configurations for positioning from multiple sets of PRS configurations; wherein the first indication information is sent by the LMF and is used to indicate the PRS configuration for positioning selected from the set of PRS configurations;

[0148] S530: Report third indication information, where the third indication information is used to instruct the base station or TPR to select a PRS configuration for positioning.

[0149] If the NRPPa message does not carry the first indication information, the base station or TPR determines a set of PRS configurations for positioning by itself, and cooperates with the UE to locate the UE.

[0150] At this time, the base station or TPR will report the TPR configuration determined by itself or recommended for use through the third indication information. The third indication information reported here may also be an NRPPa message.

[0151] After the base station or TRP reports the third indication information, the base station or TPR will receive the first indication information and / or feedback information sent by the LMF according to the third indication information, so that the base station or TPR can know the PRS configuration used for positioning this time or in the current period according to the PRS configuration used for positioning indicated by the first indication information and / or feedback information. In some embodiments, the broadcast assistance message also carries the first indication information; the method also includes: selecting the PRS configuration used for positioning from multiple sets of PRS configurations according to the first indication information.

[0152] If any NRPPa message carries the first indication information, the base station or TPR selects the PRS configuration for positioning from multiple sets of PRS configurations according to the first indication information. At this time, the base station or TRP does not need to report the third indication information. If the current base station needs to cooperate with the UE to perform positioning measurements, the PRS is sent according to the PRS configuration indicated by the first indication information, and the positioning result formed by the base station through the PRS positioning measurement is forwarded. For example, the positioning result of the UE is sent to the LMF by transparent transmission or non-transparent transmission. The positioning results here include but are not limited to: specific location information (for example, longitude and latitude information) and / or measurement results of PRS, such as PRS receiving power information, etc.

[0153] In some embodiments, Figure 4C As shown, the method also includes:

[0154] S610: receiving request information of an on-demand SI sent by a UE in an RRC connected state;

[0155] S620: According to the first indication information and the request information, a system message carrying a PRS configuration for positioning is sent to the UE via an RRC message.

[0156] If the base station is in the RRC connected state, the information exchange between the base station or TPR and the UE is relatively flexible. In order to reduce signaling overhead, if a request message from the UE is received, the base station or TPR will combine the first indication information and the request information and only send the PRS configuration for positioning to the UE through the RRC message.

[0157] In some embodiments, Figure 4D As shown, the method also includes:

[0158] S710: receiving on-demand SI request information sent by UE;

[0159] S720: Based on the request information, broadcast a system message carrying the first configuration information, and send an RRC message carrying fourth indication information; wherein the fourth indication information is determined based on the first indication information, indicating a PRS configuration selected from multiple sets of PRS configurations for positioning.

[0160] After receiving the request information, the base station or TPR will broadcast a system message, so that the UE will know the multiple PRS configurations of the current base station or TPR based on the reception of the broadcast system message. The base station or TPR will also send the fourth indication information through the RRC message. The fourth indication information and the first indication information here both point to the same set of PRS configurations for positioning, but the indication method of the indication bit may be different, and the IE carrying the fourth indication information and the first indication information are different.

[0161] In this embodiment, the UE sending the on-demand SI request information may be in an RRC connected state, an RRC idle state, or an RRC inactive state.

[0162] In some embodiments, the RRC message includes:

[0163] A first indication IE carrying fourth indication information; wherein the fourth indication information is determined based on the first indication information, indicating a PRS configuration selected from multiple sets of PRS configurations for positioning.

[0164] A dedicated first indication IE is introduced in the RRC message. The IE may include a bit sequence. One bit in the bit sequence may correspond to a set of PRS configurations. The bit value of the bit may indicate whether a certain set of PRS configurations is used for positioning.

[0165] In some embodiments, the request information is sent by the UE when the base station or TPR has not broadcast a system message including a PRS configuration or has broadcast a system message including multiple sets of PRS configurations.

[0166] In one embodiment, the UE receives a positioning request message sent by the LMF to trigger the UE to perform positioning measurement, but does not know the PRS configuration. At this time, the UE reports the on-demand SI request information.

[0167] In another embodiment, the UE receives a positioning request message sent by the LMF to trigger the UE to perform positioning measurements, and also receives multiple sets of PRS configurations sent by the base station or TPR, but currently does not know which set of PRS configurations to use for positioning measurements. At this time, the UE will report on-demand SI request information.

[0168] The UE that requests multiple sets of PRS configurations from the base station or TPR by reporting the on-demand SI request information, or that requests the fourth indication information, may be in an RRC connected state, an RRC idle state, or an RRC inactive state.

[0169] In some embodiments, the method further comprises:

[0170] Receiving a random access request from a UE in an RRC idle state or an RRC inactive state;

[0171] In response to a random access request carrying request information of the first configuration information, a system message carrying the first configuration information is broadcast, and a random access response RAR carrying fifth indication information is sent to a UE in an RRC idle state or an RRC inactive state; wherein the fifth indication information is determined based on the first indication information, indicating a PRS configuration selected from multiple sets of PRS configurations for positioning.

[0172] If the UE is in an RRC idle state or an RRC inactive state, the UE may send the first configuration information and / or the fifth indication information through a random access procedure.

[0173] The random access here may be a 2-step random access or a 4-step random access.

[0174] In the embodiment of the present application, for example, the UE carries the request information for requesting auxiliary information in a 2-step access message (Message, Msg) A. In this way, the base station or TPR will receive MsgA, and if it is found that MsgA carries the request information, it will return the message carrying the auxiliary information to the UE through a random access response, for example, MsgB.

[0175] In the embodiment of the present application, for example, the UE carries the request information for requesting auxiliary information with the access message (Message, Msg) 1 through step 4. In this way, the base station or TPR will receive Msg1, and if it is found that Msg1 carries the request information, it will return the message carrying the auxiliary information to the UE through a random access response, for example, Msg2 or Msg4.

[0176] For example, the base station carries the auxiliary information in a random access response (Random, Access Response, RAR) and carries the auxiliary information in a MAC RAR of the RAR.

[0177] In some embodiments, in response to a random access request for requesting auxiliary information, a random access response may carry a random access preamble (RAP) (Identity, ID) and fifth indication information.

[0178] In some embodiments, the fifth indication information has the same function as the first indication information, but the information content of the fifth indication information may be the same as or different from the information content of the first indication information. The information format of the fifth indication information may be the same as or different from the information format of the first indication information.

[0179] In some embodiments, the RAP ID and the fifth indication information may be carried in the same IE, for example, carried in reserved bits in the IE originally used to carry the RAP ID.

[0180] In some other embodiments, a new IE is added to the RAR or a dedicated IE is used alone to carry the fourth indication information. For example, in some embodiments, the RAR includes: a second indication IE carrying the fifth indication information.

[0181] The second indication IE may be a newly added IE in the RAR or a reserved IE in the RAR.

[0182] In some embodiments, a new MAC sub-protocol data unit (PDU) is added in the RAR to carry the fifth indication information.

[0183] In some embodiments, the second indication IE carries: a configuration identifier of a PRS configuration used for this positioning; wherein multiple communication nodes share the PRS configuration identified by the configuration identifier; the communication node is: a base station and / or a TRP;

[0184] or,

[0185] The second indication IE carries a node identifier of the communication node, wherein the node identifier has a corresponding relationship with the PRS configuration.

[0186] In some embodiments, the aforementioned first indication IE may also carry: a configuration identifier of the PRS configuration used for this positioning; wherein, multiple communication nodes share the PRS configuration identified by the configuration identifier; the communication node is: a base station and / or a TRP; or, the first indication IE may also carry a node identifier of the communication node, wherein the node identifier has a corresponding relationship with the PRS configuration.

[0187] For example, X adjacent base stations share at least one set of PRS configurations. If this set of PRS configurations is used to perform positioning measurements on the UE, the configuration identifier of this set of PRS configurations may be carried in the first indication IE and / or the second indication IE. If so, when the UE receives the configuration identifier of the PRS configuration, it will be considered that multiple base stations or TRPs share this set of PRS configurations for positioning measurements. For example, the UE completes its own positioning measurement by interacting with signals from three base stations or TPRs. At this time, if the first indication IE received by the UE carries a configuration identifier of a set of PRS configurations, the UE believes that all three base stations use this set of PRS configurations to send PRSs, thereby performing positioning measurements.

[0188] In some embodiments, a base station identifier of a base station or a TRP identifier of a TPR establishes a corresponding relationship with a PRS configuration. The PRS configurations corresponding to different communication nodes may be the same or different. For example, but not limited to: a base station or TPR has a default PRS configuration, or a preferred PRS configuration. At this time, the base station or TPR can establish a corresponding relationship with the default PRS configuration or the preferred PRS configuration. If the default PRS configuration or the preferred PRS configuration is used, the base station identifier or TRP identifier can be carried as a communication identifier. In this way, when the UE receives the first indication IE carrying the communication identifier, it will determine the node identifier of each base station or TPR based on the indication information of the corresponding relationship pre-issued by the base station or TPR to determine which set of PRS configurations to use for positioning measurement.

[0189] In another embodiment, the first indication IE and / or the second indication IE carry both a node identifier and a configuration identifier; the node identifier is used to indicate a base station and / or TPR participating in UE positioning measurement. The configuration identifier can be used to indicate a PRS configuration that a base station or TPR will use.

[0190] In some other embodiments, the first indication IE and / or the second indication IE carry both the node identifier and the configuration identifier, and carry the node identifier and the configuration identifier correspondingly; that is, one node identifier corresponds to one configuration identifier. For example, (TRP ID1, PRS configuration ID1); (TRP ID2, PRS configuration ID3). TRP ID1 is the identifier of TRP1. TRP ID2 is the identifier of TRP. PRS configuration ID1 is the identifier of PRS configuration 1. PRS configuration ID3 is the identifier of PRS configuration 3. At this time, TPR 1 indicated by the first indication IE uses PRS configuration 1; TRP2 uses PRS configuration 3.

[0191] In some embodiments, the method further comprises:

[0192] receiving a broadcast assistance message carrying second configuration information; the second configuration information comprising: at least one set of updated PRS configurations, or, second indication information; the second indication information indicating at least one set of PRS configurations to be updated;

[0193] At least one set of PRS configuration is updated according to the second configuration information.

[0194] When LMF sends the first configuration information through broadcast auxiliary information, LMF will directly send the updated PRS configuration through the second configuration information when one or more sets of PRS configurations need to be updated, or send the second indication information for updating one or more sets of PRS configurations.

[0195] The second indication information may be information indicating how to update one or more sets of PRS configurations.

[0196] In some embodiments, the method further includes: in response to receiving the second configuration information, reporting an NRPPa message carrying confirmation information, wherein the confirmation information is used to indicate confirmation of receipt of the second configuration information.

[0197] The confirmation information is used to indicate that the second configuration information sent by the LMF has been received, indicating that the current base station or TPR has received the second configuration information and updated at least one set of PRS configurations.

[0198] In some embodiments, the broadcast assistance message includes: a new radio NR downlink measurement assistance information element IE;

[0199] Among them, the NR downlink positioning reference signal auxiliary information in the NR downlink measurement assistance IE includes the first configuration information.

[0200] In this embodiment, the NR downlink measurement assistance IE in the broadcast assistance message is used to carry the first configuration information. For example, the reserved bit or reserved sequence of the NR downlink measurement assistance IE may be used to carry the first configuration information.

[0219] The RRC message includes: a first indication IE carrying fourth indication information; wherein the fourth indication information is determined based on the first indication information, and indicates a PRS configuration selected from a plurality of PRS configurations for positioning.

[0220] In some embodiments, the RRC message includes a first indication IE. The first indication IE carries fourth indication information.

[0221] In some embodiments, the first indication IE carries: a configuration identifier of the PRS configuration used for this positioning; wherein multiple communication nodes share the PRS configuration identified by the configuration identifier; the communication node is: a base station and / or a TRP; or, the first indication IE carries a node identifier of the communication node, wherein the node identifier has a corresponding relationship with the PRS configuration.

[0234] In some embodiments, the second indication IE carries: a configuration identifier of a PRS configuration used for this positioning; wherein multiple communication nodes share the PRS configuration identified by the configuration identifier; the communication node is: a base station and / or a TRP;

[0235] or,

[0236] The second indication IE carries a node identifier of the communication node, wherein the node identifier has a corresponding relationship with the PRS configuration.

[0240] In any of the above attempts, the first indication IE may be an IE newly added in the RRC message or RAR, or may be any IE that already exists in the related art but has reserved bits.

[0241] like Figure 4E As shown, an embodiment of the present disclosure provides a PRS configuration processing method, which is applied to a user equipment UE, including:

[0242] S710: Receive a positioning assistance message carrying first configuration information; wherein, the multiple sets of the PRS configurations correspond to one base station or one TRP; and the PRS configuration is used for positioning measurement of a user equipment UE.

[0243] The positioning assistance message is an LPP message sent according to the LPP protocol. It is directly transmitted to the UE by the LMF. After receiving the positioning assistance message sent by the LMF, the base station transparently transmits it to the UE.

[0244] In this way, the UE can directly receive the first configuration information carrying multiple sets of PRS configurations of a base station or a TRP from the LMF.

[0245] In some embodiments, the PRS first configuration information processing method further includes:

[0246] S720: Receive a positioning request message, where the positioning request message includes: a trigger instruction for triggering UE positioning and first indication information;

[0247] S730: Selecting, according to the first indication information, a PRS configuration for current positioning from multiple PRS configurations;

[0248] S740: Perform positioning measurement according to the trigger instruction and the PRS configuration used for this positioning.

[0249] In some embodiments, the positioning request message includes:

[0250] The third indication IE carries the first indication information.

[0251] Multiple sets of PRS configurations are sent down. When triggering the UE to make a positioning request, the first indication information is carried in the positioning request message, thereby indicating to the UE which set of the multiple sets of PRS configurations sent down is used for positioning measurement.

[0252] In some embodiments, the third indication IE carries: a configuration identifier of a PRS configuration used for positioning; wherein multiple communication nodes share the PRS configuration identified by the configuration identifier; the communication node is: a base station and / or a TRP; or, the third indication IE carries a node identifier of a communication node, wherein different node identifiers correspond to different PRS configurations.

[0253] In some embodiments, the positioning assistance message includes:

[0254] Provide assistance data IE, wherein the provide assistance data IE carries first configuration information.

[0255] The method provided in this embodiment enables the network to update the PRS configuration and quickly notify the UE of the updated PRS configuration of the network, thereby realizing dynamic PRS configuration, meeting different positioning requirements, reducing system overhead, and improving resource utilization. The solution provided in this embodiment may be as follows:

[0256] Step 1: The network (LMF) sends positioning assistance information (LPP message) to the UE, and the positioning assistance information pre-configures multiple sets of downlink PRS configurations of multiple TRPs for the UE. The downlink PRS configuration here is one of the PRS configurations provided in any of the above embodiments.

[0257] For example, taking OTDOA positioning as an example, there is NR-DL-TDOA-ProvideAssistanceDataIE in the Provide Assistance Data (ProvideAssistanceData) IE in the Positioning Assistance (LPP Provide Assistance Data) message.

[0258] The NR-DL-TDOA-ProvideAssistanceData IE contains:

[0259] NR-DL-PRS-AssistanceDataPerTRP IE, in which multiple sets of downlink PRS configurations for multiple TRPs can be configured for the UE.

[0260] The above-mentioned multiple sets of downlink PRS configurations can meet different positioning requirements and positioning accuracy of UE. For example, the multiple sets of downlink PRS configurations include different PRS transmission periods, different PRS transmission bandwidths, different PRS resource IDs and the like.

[0261] Step 2: The network sends a positioning request message to the UE, indicating in the positioning request message one of the multiple PRS configurations in the positioning assistance message in step 1.

[0262] For example, a new IE may be added, and different IE values ​​may be used to indicate different PRS configurations, that is, all TRPs in the positioning assistance information use the same PRS configuration; or a new IE may be added, including each TRP ID, and each TRP ID corresponds to a different value to indicate a different PRS configuration.

[0263] Step 3: After the UE receives the positioning request message sent by the network, it determines the PRS configuration currently used by the network in combination with the positioning assistance information sent by the network to the UE, thereby completing the positioning measurement.

[0264] Step 4: When the network needs to reconfigure the downlink PRS configuration, the network (LMF) sends a downlink PRS reconfiguration request (corresponding to the second configuration information of the aforementioned embodiment) to all base stations / TRPs in the auxiliary information sent to the UE.

[0265] The reconfiguration request includes PRS first configuration information, where the PRS first configuration information is one of the multiple PRS configurations in the above positioning assistance information.

[0266] After receiving the above PRS reconfiguration request sent by the network (LMF), the base station / TRP sends a confirmation message (NRPPa message) to the network and sends the PRS according to the received PRS configuration;

[0267] The network indicates the updated downlink PRS configuration of the network in the positioning request sent to the UE.

[0268] In this embodiment, step 1, step 2, step 3 and step 4 are only used to distinguish different steps, and do not represent the order of the steps.

[0269] In one case, steps 1 to 4 are performed sequentially. In another case, step 4 may be performed before step 2 and step 3. In still another case, step 2 may be performed before step 1; the execution order of the steps here is only an example, and the specific implementation is not limited thereto.

[0270] This embodiment includes multiple sets of downlink PRS configurations in the positioning system message, and notifies the UE of the PRS configuration currently used by the network through LPP messages, MACRAR, RRC messages, etc. At the same time, the network can dynamically update the PRS configuration in the positioning system message. The downlink PRS configuration here is one of the PRS configurations provided in any of the aforementioned embodiments.

[0271] The method provided in this embodiment can be as follows:

[0272] The network (LMF) sends the broadcast assistance information (NRPPa message) required for UE positioning to the base station / TRP. The broadcast assistance information pre-configures multiple sets of downlink PRS configurations for multiple TRPs for the UE; specifically, multiple sets of downlink PRS configurations can be configured for multiple base stations / TRPs in the NR downlink positioning reference signal assistance information (nr-DL-PRS-Assistance Data) in the NR downlink measurement assistance IE (NR-DL-Measurement-AD) in the positioning system message type 6-1 (posSibType6-1). The positioning system message type 6-1 (posSibType6-1) here is a system message.

[0273] The above multiple sets of downlink PRS configurations can meet different positioning requirements, positioning accuracy and positioning types of UE. For example, the multiple sets of downlink PRS configurations include different PRS transmission periods, different PRS transmission bandwidths, different PRS resource IDs and the like.

[0274] The network (LMF) can instruct the base station / TRP to use one of multiple sets of downlink PRS; specifically, the network can instruct the base station / TRP to use a certain set of downlink PRS configuration when sending the above-mentioned positioning broadcast assistance message.

[0275] The network (LMF) sends a positioning broadcast auxiliary information reconfiguration request to the base station / TRP, requesting to reconfigure the downlink PRS configuration. Specifically, the reconfiguration message can be implemented in the same way as step 1, or only an indication message is sent to indicate the update to one of the configurations sent in step 1.

[0276] In some cases, the base station decides to use one of the above multiple PRS configurations and informs the LMF of the result.

[0277] When the base station / TRP receives the broadcast auxiliary information required for positioning sent by the network, it broadcasts multiple sets of downlink PRS configurations in the positioning system message and can return a confirmation message to the network; and according to the instructions of the network in step 2, it determines the downlink PRS configuration and sends the PRS signal.

[0278] One way is: the network sends a positioning request (such as an LPP positioning request message) to the UE, and indicates in the positioning request message one of the multiple PRS configurations in the broadcast assistance message required for UE positioning in step 1; specifically, this can be achieved by adding a new IE. Another way is: when an RRC connected UE requests a positioning system message through an on-demand SI, if the base station broadcasts the positioning system requested by the UE in a broadcast manner, an indication message is returned to the UE, indicating one of the multiple PRS configurations in the positioning assistance information broadcast by the base station; if the base station sends the positioning system message in a dedicated manner, the system message only contains the PRS configuration currently used by the network (i.e., one of the multiple PRSs).

[0279] Another way is: when a UE in RRC idle or inactive state requests a positioning system message in an on-demand manner, an indication message is returned to indicate one of the multiple PRS configurations in the positioning assistance information broadcast by the base station. Specifically, if the UE uses random access message 1 to request, the base station only includes RAP ID and indication information in the sent MAC RAR (which can be achieved by defining a new MAC subPDU format); if the UE uses an RRC system message request (RRCSystemInfoRequest) message to request a positioning system message, the base station returns an indication message indicating one of the multiple PRS configurations in the positioning assistance information broadcast by the base station.

[0280] For another example, the above indication information can be implemented as follows: by adding a new IE, different IE values ​​indicate different PRS configurations, that is, all TRPs in the positioning assistance information use the same PRS configuration; or adding a new IE, including each TRPID, and each TRP ID corresponds to a different value to indicate a different PRS configuration.

[0281] The UE determines the PRS configuration of TRP or the first configuration information of TRP based on the received PRS configuration indication information to complete the positioning measurement.

[0282] This embodiment provides a PRS configuration processing method which can be as follows:

[0283] LMF sends positioning broadcast assistance information to the base station. The positioning broadcast assistance information contains 3 sets of downlink PRS configurations, corresponding to different positioning requirements, and instructs the base station to currently use the first one (applied to situations where positioning accuracy requirements are low and positioning types are not urgent, so as to reduce PRS overhead and improve system resource utilization).

[0284] After receiving the positioning broadcast assistance information sent by LMF, the base station broadcasts three downlink PRS configurations in the positioning system message and applies the first configuration.

[0285] When the UE needs to be positioned, if the UE requests a positioning system message through MSG1, the base station indicates in the MAC RAR that the downlink PRS configuration currently used by the base station is the first one. The positioning system message here is one of the aforementioned system messages, and the positioning system message is a system message carrying the first configuration information.

[0286] The UE completes positioning measurements according to the indicated PRS configuration.

[0287] If the network has new positioning requirements (such as high precision), the LMF instructs the gNB to apply the third configuration. After receiving the request, the gNB uses the third set of PRS configuration to send PRS.

[0288] At this time, the PRS configuration can be updated in the above manner.

[0289] like Figure 5 As shown, an embodiment of the present disclosure provides a PRS configuration processing device, which is applied to a positioning management function LMF, including:

[0290] The first sending module 510 is configured to send first configuration information carrying multiple sets of PRS configurations, wherein the multiple sets of PRS configurations correspond to one base station or one TRP; the PRS configurations are used for positioning measurement of user equipment UE.

[0294] In some embodiments, different sets of PRS configurations satisfy different positioning accuracies;

[0295] and / or,

[0296] Different PRS configurations require different positioning overheads.

[0297] In some embodiments, different sets of PRS configurations differ in at least one of the following:

[0298] PRS sending cycle;

[0299] The transmission bandwidth of PRS;

[0300] The sending resources of PRS.

[0301] In some embodiments, the apparatus further comprises:
