[0053] FIG. 1 is a schematic diagram of a wireless communication system in accordance with some embodiments of the invention. As shown in FIG. 1, the wireless communication system is a communication system based on cellular mobile communication technologies. The wireless communication system includes terminals 11 and base stations 12.

[0054] Terminal 11 may be a device that provides communication for voice and/or data to a user. Terminal 11 may communicate with one or more core networks via a radio access network (RAN, radio access network). Terminal 11 may be an Internet of Things (IoT) UE such as a touch device, a mobile phone (or "cell" phone), and a computer with an IoT UE. The terminal 11 may be a fixed, portable, handheld, hand-held, computer-embedded, or vehicle-mounted device, such as a station (STA), subscriber unit, subscriber station, mobile station, mobile device, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or UE. Alternatively, terminal 11 may also be an unmanned aerial vehicle device.

Alternatively, the terminal 11 may also be a roadside device such as a street lamp, traffic light, or other roadside device with a wireless communication function.

[0055] Base station 12 may be a network device in a wireless communication system. The wireless communication system may be a 4th generation (4G) mobile communication system, also known as a long term evolution (LTE) system. Alternatively, the wireless communication system may also be a 5th generation (5G) mobile communication system, also known as a new radio (NR, new radio) system or a 5G NR system. Alternatively, the wireless communication system may also be a next generation 5G system. The access network in the 5G system may be called a new generation-radio access network (NG-RAN) or a machine-type communication system (MTS).

[0056] Base station 12 may be an evolved base station (eNB) used in a 4G system. Alternatively, base station 12 may also be a base station (gNB) that uses a centralized distributed architecture in a 5G system. When the base station 12 adopts a centralized distributed architecture, it typically includes a central unit (CU, central unit) and at least two distributed units (DU, distributed unit). The central unit is equipped with protocol stacks of packet data convergence protocol (PDCP), radio link control (RLC) and media access control (MAC). The protocol stack of the physical (PHY) layer is installed in the DU. The specific implementation method of the base station 12 is not limited to the embodiments of the invention.

[0057] A wireless connection between base station 12 and terminal 11 may be established via an air interface. In various embodiments, the air interface may be an air interface based on the 4G mobile network technology standard, or the air interface may be an air interface based on the 5G mobile network technology standard, for example, the air interface is an NR air interface, or the air interface may also be an air interface, based on the next generation 5G mobile network technology standard.

[0058] In some embodiments of the invention, an end-to-end (E2E) connection can also be established between the terminals 11, for example, in the case of vehicle-to-vehicle communication (V2V, vehicle to vehicle), vehicle-to-infrastructure communication (V2I, vehicle to infrastructure ) and the connection of the vehicle with the pedestrian (V2P, vehicle to pedestrian) within the framework of the connection of the vehicle with all objects (V2X, vehicle to everything).

[0059] In some embodiments of the invention, the wireless communication system described above may also include a network control device 13.

[0060] The base stations 12 are respectively connected to the network control device 13 . The network manager 13 may be a core network device in a wireless communication system, for example, the network manager 13 may be a mobility management entity (MME) in an evolved packet core (EPC). Alternatively, the network management device may also be another core network device such as serving gateway (SGW, serving gateway), public data network gateway (PGW), policy and charging rules function (PCRF). function) or home subscriber server (HSS, home subscriber server). The implementation form of the network control device 13 is not limited to embodiments of the invention.

[0061] Entities involved in embodiments of the invention include, but are not limited to, terminals such as UEs that communicate on the forward link and base stations for cellular mobile communications.

[0062] An application scenario of the embodiments is that in the prior art, the core network transmits positioning assistance information to the base station via an NRPPa message, and the base station transmits it to the UE via a system message. The steps are illustrated in Fig. 2.

[0063] Through the information transfer mechanism of FIG. 2, the network side may transmit positioning assistance information to the UE. Some broadcast system messages carry positioning assistance information. The positioning assistance information includes information related to the PRS configuration(s) for the UE to perform the positioning measurement.

[0064] In addition, the UE may request an on-demand positioning system message. When the UE is in an RRC connected state, it may make a request based on a system information block (SIB) type; and, when the UE is in the RRC idle state or the idle state, it may make a request based on a system information message (SI message). The network transmits a positioning system message in accordance with a request from the UE.

[0065] PRS version R16 configuration mode is static configuration. When the UE has a positioning requirement, the network side transmits the fixed PRS configuration to the UE for positioning. It may not satisfy various positioning requirements of the UE.

[0066] As shown in FIG. 3, some embodiments of the invention provide a method for transmitting information. In a base station of a wireless communication system, the method may include the following.

[0067] In step 301, a first request message carrying the recommended PRS configuration is received.

[0068] In step 302, a target PRS configuration is determined in accordance with the recommended PRS configuration.

[0069] In step 303, the PRS is transmitted to the UE using the target PRS configuration.

[0070] The wireless communication system may include, but is not limited to, a 5G cellular mobile communication system. The UE may include a telephone terminal and the like.

[0071] In cellular mobile communications, a UE may perform PRS-based positioning. The UE may accordingly measure the time of arrival (TOA, time of arrival) of the PRSs transmitted by the plurality of base stations and perform positioning by triangulation using the time difference of the TOA and the sides of arrival of the PRS.

[0072] The first request message may be sent by the UE to request system information. The base station may transmit system information according to the content requested by the first request message, for example, the first request message may request system information for positioning.

[0073] The PRS configuration may include: PRS period, PRS occupied bandwidth, number of transmission and reception points (TRP), and the like.

[0074] The positioning accuracy obtained based on different PRS configurations may be different. For example, the shorter the PRS period and/or the denser the frequency domain, the higher the positioning accuracy. Different PRS configurations have different positioning overhead. For example, the shorter the PRS period and/or the higher the density in the frequency domain, the greater the amount of positioning overhead.

[0075] The recommended PRS configuration may be a PRS configuration determined by the UE based on its own positioning accuracy and/or load. The UE may determine the required positioning accuracy based on its own positioning scenario and determine the recommended PRS configuration. Alternatively, the UE may determine the allowable amount of positioning overhead based on its own load condition and determine the recommended PRS configuration. Different positioning scenarios have different positioning accuracy requirements. For example, pedestrian navigation requires higher positioning accuracy than car navigation. Thus, the UE may send a recommended PRS configuration that can satisfy the current positioning requirement to the base station. The recommended PRS configuration may be selected from the PRS configurations agreed in advance by the base station and the UE, or may be determined by the UE separately.

[0076] The target PRS configuration is a configuration that can be determined by the base station and finally used to transmit the PRS. The base station may determine the target PRS configuration based on the recommended PRS configuration. The target PRS configuration may be the same as or different from the recommended PRS configuration.

[0077] The base station may preset PRS configuration determination rules to determine the target PRS configuration. The recommended PRS configuration may be defined as the target PRS configuration, or a PRS configuration that is close to the recommended PRS configuration may have priority for acceptance as the target PRS configuration. Thus, the base station can determine the positioning requirement of the UE, such as positioning accuracy, based on the recommended PRS configuration, and the target PRS configuration selected by the base station can satisfy various positioning requirements of the UE as far as possible.

[0078] Thus, based on the recommended PRS configuration of the UE, a target PRS configuration is determined. On the one hand, the positioning requirement report is realized by the recommended PRS configuration, and the base station can dynamically select the target PRS configuration, so that the PRS configuration is dynamically selected and the PRS configuration selection flexibility is increased. On the other hand, the UE reports the recommended PRS configuration according to its own positioning requirement. The base station determines the target PRS configuration according to the recommended PRS configuration of the UE, which can satisfy the positioning requirement of the UE and improve the adaptability of the PRS configuration to positioning scenarios.

[0079] In some embodiments, the method may also include: transmitting system information, wherein the system information carries one or more candidate PRS configurations, and one or more candidate PRS configurations are configured for the UE to select a recommended PRS configuration in accordance with a configuration selection condition .

[0080] The base station may preset one or more possible PRS configurations based on its own load situation and/or current network support capability. One or more possible PRS configurations are sent to the UE via system information. The different possible PRS configurations may have different PRS periods and/or occupied PRS bandwidths and/or number of TRPs, and the like.

[0081] The base station may transmit system information by broadcasting. Alternatively, the base station may unicast the system information to the UE via an RRC message based on a user request.

[0082] After receiving one or more candidate PRS configurations, the UE may select a recommended PRS configuration from one or more candidate PRS configurations when there is a positioning requirement and transmit it to the base station.

[0083] A configuration selection condition may be set according to a positioning requirement. Positioning requirements may be different positioning accuracy values, and so on. Different positioning accuracy requires different PRS configurations.

[0084] Thus, the base station determines a range of possible PRS configurations, and the UE selects a PRS configuration from a range of possible PRS configurations, which reduces the cases where the UE blindly determines the recommended PRS configuration, and thus improves the PRS configuration determination efficiency.

[0085] In some embodiments, step 301 may include: receiving a first request message carrying a recommended PRS configuration identifier.

[0086] The base station can identify each possible PRS configuration. A unique configuration identifier can be set for each possible PRS configuration.

[0087] When the base station delivers PRS candidate configurations, PRS candidate IDs may be carried simultaneously.

[0088] For example, configuration identifier 1 corresponds to a possible PRS configuration including: PRS period 1, PRS frequency band 1, and the like.

[0089] After receiving the PRS candidate configurations and the PRS candidate IDs, the UE selects a recommended PRS configuration from the PRS candidate configurations and transmits the recommended PRS configuration. The UE may send a detailed configuration of the recommended PRS configuration, such as a period; it can also carry the recommended PRS configuration at the same time; or it may also send only the recommended PRS configuration ID.

[0090] Thus, when only the PRS Recommended Configuration ID is transmitted, the amount of data transmitted can be reduced, thereby reducing the amount of overhead.

[0091] In some embodiments, one or more possible PRS configurations are carried in the new radio information element (IE) downlink PRS ancillary data of the new radio type 6-1 system information downlink measurement ancillary data.

[0092] New Radio Downlink PRS Assistance Data (nr-DL-PRS-AssistanceData) in the New Radio Downlink Measurement Assistance Data (NR-DL-Measurement-AD) information element in a Type 6-1 Positioning System Message (posSibType6) -1) carry one or more possible PRS configurations.

[0093] In this way, the existing information is used to carry the possible PRS configurations, and the efficiency of using the existing information is improved.

[0094] In some embodiments, the method may also include: transmitting a target PRS configuration to the UE in response to the first request message, wherein the target PRS configuration is configured to direct the UE to receive the PRS.

[0095] If the base station does not transmit possible PRS configurations in advance, after the base station receives the recommended PRS configuration, the base station can determine the target PRS configuration in real time based on its own load situation and/or current network support capability, and transmit her on UE.

[0096] If the recommended PRS configuration is selected by the UE from one or more possible PRS configurations previously transmitted by the base station, after the base station receives the recommended PRS configuration, it can select the target PRS configuration from the possible PRS configurations that correspond to its own load situation. and/or current network support capabilities. The target PRS configuration may be the same as or different from the recommended PRS configuration.

[0097] In response to the recommended PRS configuration in the first request message, after the base station determines the target PRS configuration, it can transmit the target PRS configuration downlink to the UE, by carrying the target PRS configuration in RRC signaling, and the like.

[0098] After receiving the target PRS configuration, the UE may receive the PRS for the configuration resources such as the period and frequency band indicated by the target PRS configuration according to the target PRS configuration, and then perform positioning.

[0099] In some embodiments, the first request message may include: a first IE containing a recommended PRS configuration; and a second IE containing a system information trigger request.

[00100] The first IE is different from the second IE. The first IE may be a newly added IE, or the first IE may be an IE other than the second IE in the first request message, which has reserved bits and may carry the recommended PRS configuration.

[001 01] The UE may add an IE to the first request message to carry the recommended PRS configuration. The recommended PRS configuration can also be characterized by a configuration ID.

[00102] For example, the UE may add an IE to the first request message to carry the recommended PRS configuration identifier. For example, the PRS configuration represented by configuration identifier 1: PRS period 1 and PRS frequency band 1.

[00103] Alternatively, the UE may add an IE to the first request message to carry configuration details of the recommended PRS configuration. For example, a new IE is added, and the IE includes: PRS period, PRS bandwidth, and other information.

[00104] Using the newly added IE to carry the recommended PRS configuration can increase the amount of information carried in the existing information and improve the efficiency of the first request message.

[00105] In some embodiments, step 301

may include: receiving the first request message carrying the recommended PRS configuration sent by the UE in on-demand mode.

[00106] The on-demand mode may be a method whereby the UE receives one or more candidate PRS configurations when there is a positioning requirement, selects a recommended PRS configuration from one or more candidate PRS configurations, and transmits it to the base station.

[00107] In the on-demand mode, the UE may receive system information with possible PRS configurations only when required and/or analyze the possible PRS configurations in the system information. This can reduce the cost of the UE.

[00108] In some embodiments, receiving the first request message carrying the recommended PRS configuration sent by the UE in on-demand mode includes one of the following: receiving a DedicatedSIBRequest carrying the recommended PRS configuration; or receiving a dedicated RRCSystemInfoRequest carrying the recommended PRS configuration.

[001 09] When the UE is in the RRC connected state, the recommended PRS configuration may be carried in a DedicatedSIBRequest message.

[00110] When the UE is in an idle or idle state, the recommended PRS configuration may be carried in an RRCSystemInfoRequest message.

[00111] Thus, using different messages to carry the recommended PRS configuration can adapt to different states of the UE, which improves the adaptability of the recommended PRS configuration in the uplink.

[00112] As shown in FIG. 4, some embodiments of the invention provide a method for transmitting information. At a UE of a wireless communication system, the method may include the following.

[00113] In step 401, a first request message carrying a recommended PRS configuration is transmitted, wherein the recommended PRS configuration is configured for the base station to determine the target PRS configuration.

[00114] In step 402, a PRS is received from a base station using a target PRS configuration.

[00115] The wireless communication system may include, but is not limited to, a 5G cellular mobile communication system. The UE may include a telephone terminal and the like.

[00116] In cellular mobile communications, a UE may perform PRS-based positioning. The UE may respectively measure the TOAs of the PRSs transmitted by the plurality of base stations and perform positioning by triangulation using the time difference of the TOAs and the sides of arrival of the PRS.

[00117] The first request message may be sent by the UE to request system information. The base station may transmit system information according to the content requested by the first request message, for example, the first request message may request system information for positioning.

[00118] The PRS configuration may include: PRS period, PRS occupied bandwidth, number of transmit and receive points (TRP), and the like.

[00119] The positioning accuracy obtained based on different PRS configurations may be different. For example, the shorter the PRS period and/or the denser the frequency domain, the higher the positioning accuracy. Different PRS configurations have different positioning overhead. For example, the shorter the PRS period and/or the higher the density in the frequency domain, the greater the amount of positioning overhead.

[00120] The recommended PRS configuration may be a PRS configuration determined by the UE based on its own positioning accuracy and/or load. The UE may determine the required positioning accuracy based on its own positioning scenario and determine the recommended PRS configuration. Alternatively, the UE may determine the allowable amount of positioning overhead based on its own load condition and determine the recommended PRS configuration. Different positioning scenarios have different positioning accuracy requirements. For example, pedestrian navigation requires higher positioning accuracy than car navigation. Thus, the UE may send a recommended PRS configuration that can satisfy the current positioning requirement to the base station. The recommended PRS configuration may be selected from the PRS configurations agreed in advance by the base station and the UE, or may be determined separately by the UE.

[00121] The target PRS configuration is a configuration that can be determined by the base station and finally used to transmit the PRS. The base station may determine the target PRS configuration based on the recommended PRS configuration. The target PRS configuration may be the same as or different from the recommended PRS configuration.

[00122] The base station may preset PRS configuration determination rules to determine the target PRS configuration. The recommended PRS configuration may be defined as the target PRS configuration, or a PRS configuration that is close to the recommended PRS configuration may have priority for acceptance as the target PRS configuration. Thus, the base station can determine the positioning requirement of the UE, such as positioning accuracy, based on the recommended PRS configuration, and the target PRS configuration selected by the base station can satisfy various positioning requirements of the UE as far as possible.

[00123] Thus, based on the recommended PRS configuration of the UE, a target PRS configuration is determined. On the one hand, positioning requirement reporting is realized by the recommended PRS configuration, and the base station can dynamically select the target PRS configuration, so that the PRS configuration is dynamically selected and the PRS configuration selection flexibility is increased. On the other hand, the UE reports the recommended PRS configuration according to its own positioning requirement. The base station determines the target PRS configuration according to the recommended PRS configuration of the UE, which can satisfy the positioning requirement of the UE and improve the adaptability of the PRS configuration to positioning scenarios.

[00124] In some embodiments, prior to step 401, the method may include: receiving system information, wherein the system information carries one or more possible PRS configurations; and selecting a recommended PRS configuration from one or more possible PRS configurations in accordance with the configuration selection condition.

[00125] The base station may preset one or more possible PRS configurations based on its own load situation and/or current network support capability. One or more possible PRS configurations are sent to the UE via system information. The different possible PRS configurations may have different PRS periods and/or occupied PRS bandwidths and/or number of TRPs, and the like.

[00126] The base station may transmit system information by broadcasting. Alternatively, the base station may unicast the system information to the UE via an RRC message based on a user request.

[00127] After receiving one or more candidate PRS configurations, the UE may select a recommended PRS configuration from one or more candidate PRS configurations when there is a positioning requirement and transmit it to the base station.

[00128] A configuration selection condition may be set according to a positioning requirement. The positioning requirements may be different positioning accuracy values and the like. Different positioning accuracy requires different PRS configurations.

[00129] Thus, the base station determines the range of possible PRS configurations, and the UE selects the PRS configuration from the range of possible PRS configurations, which reduces the cases where the UE blindly determines the recommended PRS configuration, and thus improves the efficiency of PRS configuration determination.

[00130] In some embodiments, step 401 may include: sending a first request message carrying a recommended PRS configuration identifier.

[00131] The base station can identify each possible PRS configuration. A unique configuration identifier can be set for each possible PRS configuration.

[00132] When the base station delivers PRS candidate configurations, PRS candidate IDs may be carried simultaneously.

[00133] For example, configuration identifier 1 corresponds to a possible PRS configuration including: PRS period 1, PRS frequency band 1, and the like.

[00134] After receiving the PRS candidate configurations and the PRS candidate IDs, the UE selects a recommended PRS configuration from the PRS candidate configurations and transmits the recommended PRS configuration. The UE may send a detailed configuration of the recommended PRS configuration, such as a period; it can also carry the recommended PRS configuration at the same time; or it may also send only the recommended PRS configuration identifier.

[00135] Thus, when only the PRS Recommended Configuration ID is transmitted, the amount of data transmitted can be reduced, thereby reducing the amount of overhead.

[00136] In some embodiments, one or more possible PRS configurations are carried in the new radio information element (IE) downlink PRS ancillary data of the new radio type 6-1 system information downlink measurement ancillary data.

[00137] New Radio Downlink PRS Assistance Data (nr-DL-PRS-AssistanceData) in the New Radio Downlink Measurement Assistance Data (NR-DL-Measurement-AD) information element in a Type 6-1 Positioning System Message (posSibType6) -1) carry one or more possible PRS configurations.

[00138] In this way, existing information is used to carry possible PRS configurations, and the efficiency of using existing information is improved.

[00139] In some embodiments, the method may also include: determining a predetermined PRS configuration as a recommended PRS configuration in response to not receiving system information.

[00140] If the system message transmitted by the base station does not include the possible PRS configurations, or the base station does not broadcast the system positioning message required by the current UE, the UE may directly transmit the recommended PRS configuration according to different positioning requirements.

[001 41] The UE may set a plurality of predefined PRS configurations according to different positioning requirements. If system information including possible PRS configurations is not received, it selects one predefined PRS configuration from a plurality of predefined PRS configurations and determines it as a recommended PRS configuration.

[00142] In some embodiments, step 402 may include: receiving a target PRS configuration transmitted by the base station in response to the first request message, and receiving a PRS from the base station using the target PRS configuration.

[00143] If the base station does not transmit possible PRS configurations in advance, after the base station receives the recommended PRS configuration, the base station may determine the target PRS configuration in real time based on its own load situation and/or current network support capability, and transmit her on UE.

[00144] If the recommended PRS configuration is selected by the UE from one or more possible PRS configurations previously transmitted by the base station, after the base station receives the recommended PRS configuration, it can select the target PRS configuration from the possible PRS configurations that correspond to its own load situation. and/or current network support capability. The target PRS configuration may be the same as or different from the recommended PRS configuration.

[00145] In response to the recommended PRS configuration in the first request message, after the base station determines the target PRS configuration, it can transmit the target PRS configuration downlink to the UE by carrying the target PRS configuration in RRC signaling and the like.

[001 46] After receiving the target PRS configuration, the UE may receive the PRS in the configuration resources such as the period and frequency band indicated by the target PRS configuration according to the target PRS configuration, and then perform positioning.

[00147] In some embodiments, the positioning request information includes: a first IE containing a recommended PRS configuration; and a second IE containing a system information trigger request.

[00148] The first IE is different from the second IE. The first IE may be a newly added IE, or the first IE may be an IE other than the second IE in the first request message, which has reserved bits and may carry the recommended PRS configuration.

[00149] The UE may add an IE to the first request message to carry the recommended PRS configuration. The recommended PRS configuration can also be characterized by a configuration ID.

[00150] For example, the UE may add an IE to the first request message to carry the recommended PRS configuration identifier. For example, the PRS configuration represented by configuration identifier 1: PRS period 1 and PRS frequency band 1.

[00151] Alternatively, the UE may add an IE to the first request message to carry details of the recommended PRS configuration. For example, a new IE is added, and the IE includes: PRS period, PRS bandwidth, and other information.

[00152] Using the newly added IE to carry the recommended PRS configuration can increase the amount of information carried in the existing information and improve the efficiency of the first request message.

[00153] In some embodiments, step 401 may include: transmitting a first request message carrying the recommended PRS configuration in an on-demand mode.

[00154] The on-demand mode may be a method whereby the UE receives one or more candidate PRS patterns when there is a positioning requirement, selects a recommended PRS pattern from one or more candidate PRS patterns, and transmits it to the base station.

[00155] In the on-demand mode, the UE may receive system information with possible PRS configurations only when required and/or analyze the possible PRS configurations in the system information. This can reduce the cost of the UE.

[00156] In some embodiments, transmitting a first request message carrying a recommended PRS configuration in on-demand mode includes one of the following: sending a DedicatedSIBRequest carrying a recommended PRS configuration; or sending a dedicated RRCSystemInfoRequest carrying the recommended PRS configuration.

[00157] When the UE is in an RRC connected state, the recommended PRS configuration may be carried in a DedicatedSIBRequest message.

[00158] When the UE is in an idle or idle state, the recommended PRS configuration may be carried in an RRCSystemInfoRequest message.

[001 59] Thus, using different messages to carry the recommended PRS configuration can adapt to different states of the UE, which improves the adaptability of the recommended PRS configuration in the uplink.

[00160] The following is an example in combination with any of the previous embodiments of the invention.

[00161] The base station transmits a positioning system message necessary for positioning the UE. The positioning system message includes downlink PRS configuration information applicable in the current network. The network may support many possible PRS configurations.

[00162] Possible PRS configurations indicate different PRS configurations that the network can support to meet different positioning requirements. For example: different PRS periods and PRS frequency bands, different number of TRPs, etc. In detail, each possible PRS configuration can be identified, ie, each possible PRS configuration has a configuration identifier. For example, ID 1 corresponds to a possible PRS configuration: PRS Period 1, PRS Band 1. nr-DL-PRS-AssistanceData in NR-DL-Measurement-AD in Positioning System Message 6-1 (posSibType6-1) carries the set of possible PRS configurations supported by the network.

[00163] When a UE requests an on-demand positioning system message, a recommended UE PRS configuration may be carried in the request message. The recommended PRS configuration may include PRS bandwidth, PRS period, etc.

[00164] The recommended PRS configuration of the UE may be one of many possible PRS configurations transmitted by the base station; that is, the UE obtains the possible PRS configurations that the current network can support through a positioning system message, and combines the positioning type, positioning accuracy, and various positioning requirements to select one recommended PRS configuration from a plurality of possible PRS configurations supported by the network and report it. .

[00165] If the system positioning message does not include the possible PRS configurations that the network can support, or the network does not broadcast the system positioning message required by the current UE, the UE may directly broadcast the recommended PRS configuration based on different positioning requirements.

[00166] When the UE transmits request information to request a positioning system message, this can be implemented by adding an IE to the request information. Different IE values correspond to one recommended PRS configuration; for example, 01 corresponds to one recommended PRS configuration, represented by PRS period 1 and PRS bandwidth 1.

[00167] For the case where the configuration flag is not set, the UE needs to clearly indicate the recommended PRS configuration when requesting the system positioning message, eg, add a new IE that includes the PRS period, PRS bandwidth, etc.

[00168] For a UE in an RRC connected state, a PRS configuration may be recommended in a DedicatedSIBRequest message; and for an idle or idle RRC UE, a recommended PRS configuration may be added to the RRCSystemInfoRequest message.

[00169] After the network receives the positioning system message request sent by the UE, it may send an updated target PRS configuration to the UE in accordance with the recommended PRS configuration for the UE. The target PRS configuration may be the same as or different from the recommended PRS configuration.
