Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a positioning method and apparatus. Background Technology

[0002] The purpose of research on location enhancement technologies in 5G New Radio (NR) access technology is to address the location requirements of new business use cases, including general business applications and industrial IoT applications. 3GPP has already conducted location research and standardization in NR wireless communication systems in Rel-16, and Rel-17 is further researching and standardizing location from the perspectives of higher accuracy, network and terminal performance.

[0003] The existing 3GPP Release 16 positioning protocol requires terminals to perform positioning measurements within a measurement gap (MG). In the Release 16 positioning protocol, downlink positioning pilots from each base station (gNB) / transmit and receive point (TRP) are transmitted periodically. Therefore, by properly configuring the measurement gap, the downlink positioning reference signal can be made to fall within the measurement gap. Summary of the Invention

[0123] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0124] In the 3GPP Release 16 positioning system, the Positioning Reference Signal (PRS) is transmitted periodically, rather than being customized based on the terminal's positioning needs. Even when there is no positioning need on the terminal or network side, the gNB / TRP will still transmit the PRS. This results in a waste of PRS resources and interference with neighboring cells. With periodically transmitted PRS, when a terminal has a positioning need, it needs to wait for the predetermined PRS transmission time to receive the PRS. The PRS transmission period directly affects the time delay of the positioning service.

[0125] Therefore, it is necessary to discuss the transmission of on-demand PRS, that is, the network side customizes PRS for the terminal according to the QoS requirements of the location. On-demand PRS may be sent non-periodically only within a certain period of time.

[0126] The on-demand PRS resources that the terminal needs to measure may come from one or more gNB / TRPs. Under the existing positioning architecture, one way to support on-demand PRS is for the Location Management Function (LMF) to notify the UE of the on-demand PRS resource configuration. However, according to existing protocol standards, the LMF is unaware of the UE's measurement gap (MG) configuration. Therefore, the on-demand PRS provided by the LMF to the UE may not fall within the measurement gap configured for the UE.

[0127] Therefore, the positioning method and apparatus provided in this application focus on the notification and configuration of measurement gaps during the on-demand PRS transmission process.

[0128] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0129] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), 5G systems, and 5G NR systems. All of these systems include terminal equipment and network equipment.

[0130] The terminal devices involved in the embodiments of this application can be devices that provide voice and / or data connectivity to a terminal, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called user equipment (UE). Wireless terminal devices can communicate with one or more core networks via the RAN. Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the wireless access network. Examples include personal communication service (PCS) phones, cordless phones, session initiated protocol (SIP) phones, wireless local loop (WLL) stations, and personal digital assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but this application does not limit the terminology.

[0131] The network device involved in this application embodiment can be a base station, which may include multiple cells. Depending on the specific application, a base station may also be called an access point, or it may refer to a device in the access network that communicates with a wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to convert received air frames to and from Internet Protocol (IP) packets, and act as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network equipment involved in the embodiments of this application can be a base transceiver station (BTS) in a global system for mobile communications (GSM) or code division multiple access (CDMA), or a network equipment (NodeB) in wide-band code division multiple access (WCDMA), or an evolved network device (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station in a next generation system, or a home evolved node B (HeNB), relay node, femto, pico, etc., and is not limited in the embodiments of this application.

[0132] The various embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be noted that the order in which the embodiments are presented in this application represents only a chronological order and does not represent the superiority or inferiority of the technical solutions provided by the embodiments.

[0133] This application provides a method for configuring the measurement gap for on-demand PRS, including the following three solutions:

[0134] Option 1: If the terminal has already configured a periodic measurement gap (MG), the UE or serving gNB informs the LMF of relevant parameters regarding the UE's measurement gap. This allows the LMF to request each gNB (including the serving gNB and neighboring gNBs) to configure the PRS during the UE's periodic MG when the terminal requests PRS from each gNB. In this way, the UE does not need to request a new MG. The LMF can request the relevant parameters for the measurement gap from the UE or serving gNB, or the UE or serving gNB can proactively inform the LMF of the relevant parameters for the UE's measurement gap.

[0135] In Scheme 1, the LMF needs to request the gNB / UE to report the periodic MG, recommend the PRS configuration based on the periodic MG already configured in the terminal (so that the PRS is in the MG), and then tell the UE the PRS configuration provided by the gNB.

[0136] The characteristic of this first option is:

[0137] LMF recommends PRS configurations to each gNB based on the already configured MG;

[0138] gNB configures PRS according to the LMF-recommended PRS configuration.

[0139] LMF will notify the UE of the gNB's PRS configuration.

[0140] The standardization impact of this scheme is as follows:

[0141] 1. The UE or gNB informs the LMF of the UE's measurement gap.

[0142] 2. LMF informs the serving cell and / or neighboring cells of the on-demand PRS configuration range.

[0143] Option 2: LMF determines the on-demand PRS transmission time based on whether the terminal supports positioning measurement without measurement gaps.

[0144] If the terminal supports positioning measurements without measurement gaps, the LMF recommends the optimal PRS configuration (e.g., minimum latency) to each gNB based on the terminal's capabilities.

[0145] If the terminal does not support positioning measurements without measurement gaps, the LMF should reserve time for MG reconfiguration between the time the terminal is notified of on-demand PRS and the time the UE detects the PRS when requesting on-demand PRS from each gNB (including the serving gNB and each neighboring gNBs). Therefore, after receiving the on-demand PRS configuration information, the UE can request the base station to configure or update the MG if necessary (i.e., if the on-demand PRS does not fall within the configured MG), and the serving cell will reconfigure the measurement gap according to the UE's request. This second scheme reduces latency compared to the first scheme.

[0146] The key features of this scheme are:

[0147] LMF recommends the best PRS configuration to each gNB based on the UE's capabilities;

[0148] The UE requests the configuration and reconfiguration of the MG based on the transmission time period of the on-demand PRS;

[0149] LMF should allow time for MG reconfiguration between the time it notifies the terminal of on-demand PRS and the time the UE detects PRS.

[0150] The standardization impact of this scheme is as follows:

[0151] The terminal reports whether it supports positioning measurements without measurement gaps.

[0152] LMF notifies the terminal of the on-demand PRS transmission time.

[0153] Option 3: The LMF requests or notifies the serving base station via the UE to reconfigure the MG. When configuring on-demand PRS, the serving cell and neighboring cells notify the LMF of candidate or actually sent on-demand PRS information. The LMF recommends MG information based on the on-demand PRS configuration information of the serving cell and neighboring cells, and then sends the recommended MG information to the serving cell. Alternatively, the LMF may notify the UE of the MG before notifying it of on-demand PRS, so that the UE obtains the reconfigured MG before detecting on-demand PRS. This option has lower latency and fewer signaling interactions for updating measurement gaps.

[0154] The characteristics of this solution are as follows (discussing the characteristics of solution three in conjunction with different implementation schemes of on-demand PRS):

[0155] Option 3-1:

[0156] Step 1: The serving gNB and neighboring gNBs report the candidate PRS resource pools to the LMF.

[0157] Step 2: LMF determines the recommended PRS information based on the candidate PRS resource pool. The recommended PRS information includes one or a combination of the following:

[0158] The on-demand PRS or on-demand PRS corresponds to the start time of the measurement gap;

[0159] The on-demand PRS or the on-demand PRS corresponding to the stop time of the measurement gap;

[0160] The duration of the on-demand PRS or on-demand PRS corresponding to the measurement gap;

[0161] The period corresponding to the on-demand PRS or on-demand PRS measurement gap;

[0162] On-demand PRS testing opportunities;

[0163] The number of repetitions of on-demand PRS or the corresponding measurement interval;

[0164] Time slots containing on-demand PRS.

[0165] The recommendation information in the PRS is requested by the user or base station.

[0166] Step 3: The LMF sends the recommended PRS or PRS parameters to the serving gNB and neighboring gNBs, and at the same time recommends the best MG configuration to the serving cell.

[0167] Specifically, if the LMF sends the recommended PRS parameters to the serving gNB and the neighboring gNB, the serving gNB and the neighboring gNB send an on-demand PRS request response to the LMF to determine the on-demand PRS configuration.

[0168] Step 4: The service cell performs MG reconfiguration based on the recommended MG.

[0169] The standardization impact of this scheme is that the first three steps mentioned above all affect standardization.

[0170] Option 3-2:

[0171] Step 1: The LMF will notify each base station of the expected On-demand PRS parameters, i.e., the recommended PRS information, based on the UE's positioning needs.

[0172] These on-demand PRS parameters include one or a combination of the following:

[0173] The on-demand PRS or on-demand PRS corresponds to the start time of the measurement gap;

[0174] The on-demand PRS or the on-demand PRS corresponding to the stop time of the measurement gap;

[0175] The duration of the on-demand PRS or on-demand PRS corresponding to the measurement gap;

[0176] The period corresponding to the on-demand PRS or on-demand PRS measurement gap;

[0177] On-demand PRS testing opportunities;

[0178] The number of repetitions of on-demand PRS or the corresponding measurement interval;

[0179] Time slots containing on-demand PRS.

[0180] The serving cell can determine the MG's time information and frequency based on the start and end times of on-demand PRS transmissions and the frequency of on-demand PRS transmissions.

[0181] Step 2: The serving cell and neighboring cells configure on-demand PRS according to the desired on-demand PRS parameters and notify the LMF to configure on-demand PRS.

[0182] Step 3: Based on these configured on-demand PRS, LMF notifies the UE of the on-demand PRS that needs to be measured. These PRS that need to be measured are the PRS that are actually sent.

[0183] LMF can be configured in this step to notify the service cell MG.

[0184] Step 4: When the actual PRS sent is different from the on-demand PRS configured by the base station, the LMF should notify the base station to finally notify the UE of the PRS measured, so that the resources corresponding to other PRS not used for UE measurement will be applied to other transmissions.

[0185] The standardization impact of this scheme is that all four steps mentioned above affect standardization.

[0186] The table below compares the characteristics and other features of these three schemes:

[0187]

[0188] The choice of which scheme to adopt among the above options can be determined through higher-layer signaling or protocol agreement. For example, higher-layer signaling could involve the base station instructing the UE to choose a scheme via RRC signaling. The following descriptions will cover both unilateral and implementation processes.

[0189] Descriptions are provided from the perspectives of the LMF side, base station side, and UE side:

[0190] The execution process on the LMF side specifically includes:

[0191] Step 1: The LMF sends a request for On-demand PRS related information to each base station or terminal.

[0192] The request specifically includes one or a combination of the following:

[0193] On-demand PRS candidate configuration request;

[0194] On-demand PRS configuration request;

[0195] MG information;

[0196] Terminal capability information indicates whether the terminal supports positioning measurements without measurement gaps.

[0197] The On-demand PRS configuration request includes the configuration time period of the on-demand PRS, i.e., the information of the on-demand PRS.

[0198] The On-demand PRS candidate configuration request is a request to provide the configuration time period (i.e., the resource pool of the time period) of the candidate on-demand PRS.

[0199] The key feature of this step is that the LMF sends an information request to each base station and sends a measurement MG; the on-demand PRS of each base station should fall within the measurement MG. This process corresponds to Scheme 1.

[0200] Step 1 may include, for example, the LMF requesting the terminal or base station whether the terminal supports reporting positioning measurement capabilities without measurement gaps;

[0201] Step 1 may further include: requesting the reporting of the measurement gap information from the terminal or the base station. The terminal may report the measurement gap information directly to the LMF, or it may report it to the LMF through the base station.

[0202] Step 2: The LMF receives the first relevant information from the On-demand PRS notified by the serving cell and / or UE;

[0203] The first relevant information of the On-demand PRS includes one or a combination of the following:

[0204] On-demand PRS candidate configurations;

[0205] On-demand PRS configuration;

[0206] MG information;

[0207] Terminal capability information.

[0208] For example, step 2 may include:

[0209] Does the LMF receiving terminal or the terminal reported by the base station support the ability to perform positioning measurements without measurement gaps?

[0210] Step 2 may further include: the LMF receiving on-demand PRS candidate configurations sent by the base station. Subsequent steps can then determine recommended on-demand PRS information based on these candidate configurations.

[0211] The key feature of this step is:

[0212] The time and location of the gNB notification to the LMF MG specifically include (corresponding to Scheme 1):

[0213] Before requesting a location service, the serving cell notifies the LMF of the MG information of the terminal to be located;

[0214] Alternatively, when configuring on-demand PRS, the serving cell may notify the LMF terminal of the current MG time.

[0215] Alternatively, the time and location at which the UE notifies the LMF MG specifically includes:

[0216] When reporting capabilities, the UE notifies the MG of the time and location (Scheme 2), and / or whether the terminal supports positioning measurement without measurement gaps (Scheme 1).

[0217] The time position for the gNB / UE to notify the LMF MG specifically includes (corresponding to Scheme 1): the LMF notifies the neighbor cell on-demand PRS at the expected time position, which is within the MG. This can reduce the signaling notification time.

[0218] Step 3: The LMF notifies the terminal / serving cell of the second relevant information of the on-demand PRS.

[0219] The second relevant information for on-demand PRS includes: on-demand PRS configuration, at least one of MG.

[0220] For example, step 3 may specifically include:

[0221] Determine recommended information for on-demand PRS and send it to the base station and / or terminal to control PRS measurements during measurement intervals.

[0222] Furthermore, step 3 may also include: sending on-demand PRS configuration to the terminal, wherein the on-demand PRS configuration may be an on-demand PRS configuration sent by the base station, and the on-demand PRS configuration is determined by the base station based on the on-demand PRS recommendation information.

[0223] Optionally, LMF can determine the recommended information for the on-demand PRS based on the measurement gap already configured in the terminal.

[0224] Alternatively, LMF determines the on-demand PRS recommendation information based on whether the terminal supports positioning measurement without measurement gaps.

[0225] In addition, the recommendation information for the on-demand PRS can also be determined based on the on-demand PRS candidate configuration.

[0226] The on-demand PRS recommendation information includes, for example, recommended measurement gap configuration information; the LMF sends the on-demand PRS recommendation information to the terminal, specifically including:

[0227] LMF sends recommended measurement gap configuration information to the serving base station of the terminal based on the on-demand PRS configuration information of the terminal's serving cell and neighboring cells;

[0228] Alternatively, before notifying the terminal of on-demand PRS, LMF sends recommended measurement gap configuration information to the terminal.

[0229] Specifically, for example:

[0230] a) If the terminal does not support positioning measurements without measurement gaps, the time between the LMF notifying the on-demand PRS and the UE detecting the PRS should be reserved for MG reconfiguration. After receiving the on-demand PRS configuration information, the UE requests an update to the MG from the base station, and the serving cell reconfigures the measurement gap according to the UE's request. According to the higher-layer assessment, the configuration time required for the periodic MG is 13ms to 13.5ms, making this scheme suitable for situations with high latency. This paragraph corresponds to Scheme Two. Or,

[0231] b) The LMF notifies the base station or UE of relevant information regarding MG reconfiguration. The LMF determines the recommended MG information based on the on-demand PRS configuration information of the serving cell and / or neighboring cells, and then the LMF sends the recommended MG information to the serving cell, or the LMF sends the MG information to the UE.

[0232] Specifically, the LMF sending the MG information to the serving cell includes: when the LMF sends an Observed Time Difference of Arrival (OTDOA) information request to the serving cell, it notifies the time information for MG reconfiguration; or when the LMF sends an on-demand PRS request to the serving cell or notifies that an on-demand PRS has been sent, it explicitly or implicitly notifies the serving gNB of the time location of the measurement gap.

[0233] The LMF sends the MG information to the UE, including: when the LMF sends a UE capability request or auxiliary data to the UE, it notifies the UE of the time and location of the measurement gap.

[0234] Alternatively, the LMF may send the MG information to the UE, including sending a measurement gap to the UE before sending on-demand PRS information to the terminal. The UE can obtain the measurement gap in advance and configure it accordingly, reducing latency.

[0235] The execution process on the serving cell side (i.e., the base station side) specifically includes:

[0236] Step 1: The serving cell receives an LMF information request, which is used to obtain one or a combination of the following information:

[0237] On-demand PRS candidate configurations;

[0238] On-demand PRS configuration;

[0239] MG information;

[0240] Information on whether the terminal supports positioning measurement without measurement gaps.

[0241] Step 2: The serving cell notifies the LMF of the first relevant information on the On-demand PRS.

[0242] Accordingly, the first relevant information of On-demand PRS includes at least one of: On-demand PRS candidate configuration, and / or on-demand PRS configuration, and / or MG information, and / or terminal capability information.

[0243] The time and location (i.e., MG information) of the MG notified to the LMF by the gNB includes: the serving cell notifying the LMF of the MG information of the terminal to be located before the location service request; or the serving cell notifying the LMF of the time of the MG location of the terminal when configuring on-demand PRS.

[0244] The time position of the gNB notification to the LMF MG also includes: the expected time position of the LMF notification to the neighboring cell on-demand PRS, which is within the MG.

[0245] Step 3: Receive LMF notification on-demand PRS second relevant information.

[0246] The second relevant information for on-demand PRS includes the recommendation information for on-demand PRS determined by LMF.

[0247] The recommended information for the on-demand PRS includes recommended measurement gap information, i.e., the time position of the MG.

[0248] The second relevant information for on-demand PRS may also include: on-demand PRS configuration.

[0249] Specifically, the LMF notifies the base station of the time information for reconfiguring the MG. The LMF determines the recommended information for the MG based on the configuration information of the on-demand PRS of the serving cell and / or neighboring cells. Therefore, the serving cell receives the MG recommendation information sent by the LMF.

[0250] The serving cell receives MG recommendation information from the LMF, such as receiving an OTDOAINFORMATION REQUEST from the LMF and obtaining the MG recommendation information, i.e., the time information for reconfiguring the MG. Alternatively, the serving cell receives an on-demand PRS request from the LMF or a notification sent via on-demand PRS, and the serving gNB learns the time position of the measurement gap explicitly or implicitly.

[0251] Step 4: The serving cell sends an on-demand PRS.

[0252] The execution process on the UE side specifically includes:

[0253] Step 1: The UE provides the LMF with the On-demand PRS requirement information;

[0254] The On-demand PRS demand information includes at least one of the following: On-demand PRS demand information, MG, and terminal capability information.

[0255] The UE provides On-demand PRS requirement information to the LMF, including: the UE provides On-demand PRS requirement information to the LMF based on the LMF's information request.

[0256] The UE notifies the LMF MG of the time and location, including: the UE notifies the MG of the time and location when reporting capabilities, and / or whether the terminal supports positioning measurement without measurement gaps.

[0257] The UE notifies the LMF of the MG at the desired time, which also includes the LMF notifying the neighbor cell on-demand PRS at the desired time, which is within the MG. This can reduce the signaling notification time.

[0258] Step 2: Receive the second relevant information of the on-demand PRS from the LMF notification.

[0259] The second relevant information for on-demand PRS includes: on-demand PRS configuration, and / or at least one of MG.

[0260] The LMF notifies the UE of the timing information for reconfiguring the MG. The LMF determines the MG configuration information based on the on-demand PRS configuration information of the serving cell and / or neighboring cells, and then the LMF sends the MG information to the serving cell, or the LMF sends the MG information to the UE.

[0261] The LMF sends the MG information to the serving cell, and the serving cell also notifies the UE of the MG information.

[0262] The LMF sending the MG information to the UE includes: when the LMF sends a UE capability request to the UE, it notifies the UE of the time and location of the measurement gap.

[0263] Step 3: The UE receives the on-demand PRS and performs on-demand PRS detection.

[0264] The following describes the overall process:

[0265] Option 1: Before the LMF determines the PRS, it obtains the periodic MG from the UE / gNB notification, thus the LMF determines the PRS resource within the MG. If the terminal has already configured a periodic MG, the LMF reserves a PRS configuration delay when determining the PRS for the terminal, allowing the PRS to be configured within the periodic MG. This way, the UE does not need to request a new MG, but the PRS still needs to be configured based on the periodic MG.

[0266] gNB notifies LMF MG of the time and location.

[0267] One implementation method (Option 1): Before requesting a location service, the serving cell notifies the LMF of the MG information of the terminal to be located.

[0268] Another implementation method (Option 2): When configuring on-demand PRS, the serving cell notifies the LMF of the time where the terminal's MG is located. The LMF then notifies the neighboring cells of the desired time and location of on-demand PRS, which is within the MG.

[0269] The UE notifies the LMF MG of the time and location.

[0270] When the UE reports its capabilities, it notifies the MG of the time and location. The LMF then notifies the neighboring cell of the desired time and location of the on-demand PRS, which is within the MG.

[0271] Option 2: LMF reserves space for PRS configuration on the terminal based on its capabilities:

[0272] If the terminal supports positioning measurements without measurement gaps, the LMF determines the low-latency PRS for the terminal without considering measurement gaps.

[0273] If the terminal does not support positioning measurements without measurement gaps, and the terminal needs to configure periodic / non-periodic measurement (MG), the LMF needs to allow time for the terminal to make MG requests and configure MG when determining the PRS for the terminal. According to the high-level assessment, the configuration time for periodic MG is 13ms to 13.5ms, and this solution is suitable for situations with high latency.

[0274] Option 3: The LMF notifies the base station or UE to reconfigure the MG's time information.

[0275] For example, when the serving cell and neighboring cells configure on-demand PRS, they notify the LMF of the on-demand PRS information. The LMF determines the MG configuration information based on the on-demand PRS configuration information of the serving cell and neighboring cells. Then, the LMF sends the MG information to the serving cell in an explicit or implicit manner, and the serving cell then notifies the UE of the MG information, or the LMF sends the MG information to the UE. Here, implicit means that the LMF notifies the base station of the on-demand PRS configuration, and the base station infers the measurement gap based on the on-demand PRS.

[0276] gNB notification method:

[0277] Option 1: When the LMF sends an OTDOA INFORMATION REQUEST to the serving cell, it notifies the time information for reconfiguring the MG.

[0278] Option 2: When the LMF sends an on-demand PRS request or notification to the serving cell, it may explicitly or implicitly notify the serving gNB of the time location of the measurement gap.

[0279] UE is notified in the following ways:

[0280] Option 1: When sending a UE capability request to the UE, the LMF notifies the UE of the time position of the measurement gap.

[0281] The following are detailed descriptions of several embodiments.

[0282] Example 1 (corresponding to Scheme 2):

[0283] Based on the UE's capabilities, the LMF recommends the optimal PRS configuration to each gNB. The UE requests MG configuration and reconfiguration based on the on-demand PRS transmission time period. The LMF ensures that time for MG reconfiguration should be reserved between the on-demand PRS notification time and the UE's PRS detection time. This scheme determines the on-demand PRS transmission time based on the terminal's capabilities, thus adaptively adjusting the delay based on those capabilities.

[0284] The implementation process of this embodiment is combined with Figure 1 illustrate:

[0285] Step 2-1: The LMF requests location capability from the UE and receives terminal capability information from the UE.

[0286] LMF determines the on-demand PRS resources based on whether the terminal supports positioning measurement without measurement gaps. If the terminal does not support positioning measurement without measurement gaps, the transmission time of the on-demand PRS determined by LMF should reserve time for MG configuration between the time the terminal receives the on-demand PRS.

[0287] Step 2-2: The UE provides positioning capabilities to the LMF.

[0288] Steps 2-3: The UE requests location assistance data from the LMF.

[0289] Steps 2-4: The LMF provides positioning assistance data to the UE, that is, it notifies the UE of the on-demand PRS configuration.

[0290] Steps 2-5: The LMF requests location information from the UE.

[0291] Steps 2-6: The UE performs positioning measurements to determine the positioning information.

[0292] Steps 2-7: The UE provides location information to the LMF.

[0293] Steps 2-8: LMF performs positioning calculations based on the positioning information provided by the UE.

[0294] Example 2 (corresponding to Scheme 1):

[0295] In this embodiment, the LMF recommends PRS configurations to each gNB based on the already configured MG; then, the gNB configures the PRS according to the LMF's recommended PRS configuration; further, the LMF notifies the UE of the PRS configuration. To enable on-demand PRS configuration requests, either the gNB or the UE needs to report MG-related information to the LMF. This scheme utilizes existing MGs and does not require MG reconfiguration.

[0296] The implementation process of this embodiment is combined with Figure 2 The specific process includes:

[0297] Step 3a-1: The LMF sends an information request to the base station, which includes a request for the base station to report the UE's MG information.

[0298] Step 3a-2: The LMF receives the information response from the base station and obtains the UE's MG information reported by the base station. The LMF notifies the UE of the on-demand PRS configuration, which falls within the MG in step 1.

[0299] Example 3 (corresponding to Scheme 3):

[0300] In this embodiment, each base station notifies the LMF of the candidate resource pool for on-demand PRS. The LMF determines the actual PRS to be sent from the pool and determines the recommended MG based on the actual PRS to be sent, and then notifies the gNB of the recommended MG.

[0301] The specific process of this embodiment includes:

[0302] LMF sends information requests to each base station;

[0303] LMF receives information responses from the base station and obtains candidate On-demand PRS configuration information (i.e., the candidate resource pool of on-demand PRS) from them;

[0304] The base station includes the base station of the serving cell and the base station of the neighboring cells.

[0305] LMF determines the on-demand PRS that the UE needs to measure from these candidate on-demand PRS, determines the recommended MG based on the union of the transmission times of these on-demand PRS, notifies each base station of these on-demand PRS, and notifies the serving cell of the recommended measurement interval.

[0306] The base station receives the on-demand PRS and recommended measurement gaps sent by the LMF to the UE, reconfigures the measurement gaps according to these on-demand PRSs, and notifies the UE of the reconfigured content.

[0307] In this embodiment, after the LMF determines the actual on-demand PRS, it notifies the base station of the actual on-demand PRS and simultaneously notifies the recommended MG. Without additional signaling interaction, the recommended MG is promptly notified to the base station using the signaling required in the on-demand PRS.

[0308] Example 4 (corresponding to Scheme 3):

[0309] In this embodiment, when the LMF sends an on-demand PRS information request to the serving gNB, it notifies the gNB of the recommended MG information. The LMF also notifies neighboring cells of the on-demand PRS configuration range, and the serving cell and neighboring cells configure on-demand PRS within the recommended MG.

[0310] The LMF implementation process in this embodiment includes:

[0311] Step 1: The LMF sends an on-demand PRS information request to each base station and sends an MG. The on-demand PRS of each base station should fall on the MG.

[0312] The On-demand PRS information request includes the configuration time period of the on-demand PRS.

[0313] Step 2: The LMF receives the on-demand PRS sent by each base station and notifies the UE of these on-demand PRS.

[0314] The process of serving the cell base station side includes:

[0315] Step 1: The base station receives the measurement gap sent by the LMF;

[0316] Step 2: The base station configures on-demand PRS according to the measurement gap sent by LMF. On-demand PRS should be within the measurement gap. The base station then reconfigures the measurement gap and notifies the UE of the reconfigured content.

[0317] In this scheme, the LMF needs to determine the on-demand PRS transmission time period based on positioning requirements. The LMF needs to notify each cell of the on-demand PRS transmission time period. When notifying the serving cell of the on-demand PRS transmission time period, the MG explicitly notifies the serving cell, or the protocol specifies that it is calculated from the on-demand PRS transmission time periods of the notified cells. This scheme, without additional signaling interaction, utilizes the necessary signaling in on-demand PRS to promptly notify the base station of the recommended MG.

[0318] Example 5 (corresponding to Scheme 3):

[0319] In this embodiment, the LMF notifies the UE once it determines the recommended MG, so that the UE can apply for an MG update as soon as possible.

[0320] The process on the LMF side in this embodiment:

[0321] Step 1: Before notifying the UE of on-demand PRS resources, the LMF notifies the UE of the measurement gap.

[0322] Step 2: The LMF sends on-demand PRS to the UE and notifies the UE of the configuration of these on-demand PRS (i.e., the time position of the on-demand PRS resources).

[0323] The process on the UE side:

[0324] Step 1: The UE receives the measurement gap sent by the LMF and sends a measurement gap reconfiguration request to the base station;

[0325] Step 2: UE receives LMF notification on-demand PRS configuration.

[0326] After obtaining the on-demand PRS, the terminal initiates an MG update request to the serving cell based on the time and location of the on-demand PRS resource, and then waits for the base station to configure the MG. In this embodiment, when the LMF determines the recommended MG, the LMF will send the recommended MG to the terminal before sending the on-demand PRS configuration, such as when requesting positioning capabilities, thereby reducing latency.

[0327] In summary, the embodiments of this application ensure that PRS measurements can be performed during measurement intervals during the on-demand PRS transmission implementation. Specifically, this includes:

[0328] The base station / UE reports to the LMF whether the UE supports location measurement without measurement gaps. Based on this capability, the LMF determines the configured on-demand PRS transmission time and notifies the UE of the time interval between adjacent on-demand PRS.

[0329] Before the LMF notifies the UE of the on-demand PRS, the base station / UE informs the LMF of the UE's measurement gap. The LMF determines the expected time period of the on-demand PRS and notifies the neighboring cells of this time period so that the PRS configured in each cell is within the measurement gap.

[0330] LMF determines the on-demand PRS based on the candidate PRS and notifies the serving cell base station of the measurement gap, and the serving cell base station reconfigures the measurement.

[0331] LMF notifies the serving cell of the measurement gap that the serving cell will configure PRS within the measurement gap, and also notifies neighboring cells that the configured on-demand PRS will also be within the measurement gap.

[0332] Before notifying the UE of on-demand PRS resources, LMF notifies the UE of the measurement gap. The UE can obtain the measurement gap in advance and configure the measurement gap in advance, thereby reducing latency.

[0333] Therefore, this application provides a method for ensuring that PRS can be measured during the measurement gap under on-demand PRS. Depending on different application scenarios, the measurement gap configuration corresponding to on-demand PRS can be achieved with minimal impact on existing standards, or a low-latency measurement gap configuration corresponding to on-demand PRS can be achieved.
