Abstract
Description
Technical Field
[0001] This application belongs to the field of wireless communication technologies, and particularly relates to a method, apparatus, terminal, and network-side device for configuring a measurement gap request. Background Art
[0002] Taking the NR positioning of a New Radio (NR) communication system as an example, positioning reference signals (PRS) are introduced for a user equipment (UE) to perform positioning measurements. During actual measurements, the UE needs to measure the PRS broadcast by multiple cells. However, in order to ensure high-precision positioning measurements, the network-side device configures a PRS with a large bandwidth, which may sometimes exceed the range of the active bandwidth part (BWP) where the UE is currently operating. Therefore, to enable the UE to measure the PRS outside the active BWP, the NR communication system allows the UE to use a measurement gap to measure the PRS outside the active BWP.
[0003] When the UE expects to measure the PRS outside the active BWP or the PRS with a different numerology from the active BWP parameter set, the UE can send a measurement gap request to the gNB to request the gNB to configure a measurement gap for it, and the gNB can determine whether to configure a measurement gap for the UE according to its own situation.
[0004] However, in the related art, the decision of whether to configure a measurement gap for the UE is the behavior of the gNB itself, and the UE does not know whether the gNB has configured a measurement gap, so it is impossible to determine the bandwidth for measuring the PRS.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.
[0035] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are usually of the same category, and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means that the related objects before and after are in an "or" relationship.
[0036] It should be noted that the technology described in the embodiments of the present application is not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, and can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems.

However, the following description describes the New Radio (NR) system for example purposes, and the NR term is used in most of the following descriptions, although these technologies can also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems. th Generation, 6G) communication systems.
[0037] Figure 1The block diagram of a wireless communication system to which the embodiments of the present application can be applied is shown. The wireless communication system includes a terminal 11 and a network-side device 12. Among them, the terminal 11 can also be called a terminal device or a user terminal. The terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), etc. Terminal-side devices.

[0038] The network-side device 12 can be a base station, a core network or a positioning server, etc. Among them, the base station can be called a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting and receiving point (TRP), or some other suitable term in the field. As long as the same technical effect is achieved, the base station is not limited to a specific technical term. It should be noted that in the embodiments of the present application, only the base station gNB in the NR system is taken as an example, but the specific type of the base station is not limited. For example, the base station gNB can also be represented by a serving cell, etc.
[0039] Next, in conjunction with the accompanying drawings, the technical solutions provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.
[0040] As Figure 2 shown, it is a schematic flowchart of a measurement interval configuration request method 200 provided by an exemplary embodiment of the present application. The method 200 can be applied to a base station and can be specifically executed by hardware or software in the base station. Referring again to Figure 2 , the method 200 may at least include the following steps.
[0041] S210, receive a measurement interval request sent by a terminal and / or a location server.
[0042] Wherein, the measurement interval request is used to instruct the base station to configure a measurement interval for downlink positioning reference signal measurement.
[0043] Optionally, the downlink positioning reference signal includes, but is not limited to, at least one of signals such as PRS, Synchronization Signal and PBCH block (SSB), Tracking Reference Signal (TRS), CSI Reference Signal (CSI-RS), etc.
[0044] In addition, the downlink positioning reference signal measurement can be a conventional measurement or an on-demand measurement. Correspondingly, the downlink positioning reference signal configuration mentioned in subsequent embodiments can be a conventional configuration or an on-demand configuration; the positioning base station participating in the positioning measurement can be the base station participating in the positioning in conventional positioning or the base station participating in the positioning in on-demand positioning; the location server can be a network node / device that determines the conventional downlink positioning reference signal configuration or a network node / device that determines the on-demand downlink positioning reference signal configuration, and this embodiment does not limit this.
[0045] In practical applications, when the location server sends the measurement interval request to the base station, it can be sent directly or indirectly. For example, the location server can directly transmit the measurement interval request to the base station only through one signaling, such as signaling LPPa, etc.; or for another example, the location server can also transmit the measurement interval request to the base station through multiple signaling between multiple nodes. For example, the location server can first send the measurement interval request to the terminal, and then the terminal forwards it to the base station, etc., and this embodiment does not limit this. Correspondingly, when the base station sends the feedback information described in S220 to the location server, it can also be sent directly or indirectly, etc., and specifically, it can refer to the process of the location server sending the measurement interval request to the base station.
[0046] It can be understood that in the embodiments given in this application, the location server is a network node that determines the downlink positioning reference signal configuration, and the base station refers to the base station that currently provides services for the terminal. In addition, the measurement interval request received by the base station from the terminal in S210 can be sent independently by the terminal or can be a forwarded measurement interval request corresponding to the location server, and this embodiment does not limit this.
[0047] S220, perform at least one of the following according to the measurement interval request: configure a measurement interval for downlink positioning reference signal measurement, and send feedback information to the terminal and / or the location server.
[0048] Wherein, the feedback information is used to indicate whether the base station configures a measurement interval for downlink positioning reference signal measurement. In practical applications, if the base station configures the measurement interval, the base station may, after configuring the measurement interval, send the measurement interval configuration to the terminal and / or the location server. Thus, the terminal can perform the measurement of the positioning reference signal according to the measurement interval, or the location server can confirm according to the feedback that the configuration of the positioning reference signal does not need to be adjusted to perform the next positioning step. Of course, the base station can also determine whether to send feedback information indicating that the base station configures the measurement interval to the terminal and / or the location server according to actual requirements. For example, if the configuration of the measurement interval is supported, no feedback information is sent, implicitly indicating that the measurement interval is supported / configured, etc.
[0049] In practical applications, the base station may configure the measurement interval after sending the feedback information; or configure the measurement interval after the start time of the measurement interval indicated by the measurement interval request, which can be specifically set according to actual requirements.
[0050] After the base station configures the measurement interval and under the condition of meeting a predetermined condition, stop the measurement interval; wherein, the predetermined condition may include at least one of the following:
[0051] (1) Receive a measurement interval stop signaling. Wherein, the measurement interval stop signaling may be sent by the terminal or the location server or other network nodes.
[0052] (2) When the measurement interval request includes the effective duration of the measurement interval, the current effective time of the measurement interval reaches the interval effective duration.
[0053] (3) When the measurement interval request includes the cut-off time of the measurement interval, the current time reaches the cut-off time of the measurement interval.
[0054] In this application, the measurement interval request may indicate that the base station feeds back to the terminal and / or the location server whether a measurement interval for downlink positioning reference signal measurement can be configured, so that when the base station determines whether to configure the measurement interval according to its own situation, it feeds back whether the measurement interval is configured.
[0055] Alternatively, the terminal and / or the location server may not indicate to the base station to feed back whether the measurement interval can be configured through the measurement interval request, but the base station actively feeds back whether the measurement interval is configured.
[0056] If the base station feeds back to the terminal whether the measurement interval can be configured, the terminal can, based on this feedback, determine whether to perform the measurement of the downlink positioning reference signal on the active DL BWP or perform the measurement of the downlink positioning reference signal during the measurement interval. If the base station feeds back to the location server whether the measurement interval can be configured, the location server can, based on this feedback, determine the configuration of the downlink positioning reference signal such as the bandwidth, and then notify other positioning base stations participating in the positioning to avoid multiple positioning base stations participating in the positioning from sending downlink positioning reference signals with a large bandwidth or overhead according to the previous configuration, thus causing the problem of waste of downlink positioning reference signal resources.
[0057] It should be noted that, similar to the foregoing S210, when the base station sends the feedback message and / or the measurement interval configuration to the location server, it can be sent directly or indirectly, and this embodiment does not limit this.
[0058] In the foregoing measurement interval configuration request method 200 given in this embodiment, by receiving the measurement interval request sent by the terminal or / and the location server, the base station can, while determining whether to configure the measurement interval, also feed back the feedback information indicating whether to configure the measurement interval to the terminal or / and the base station, and finally enable the location server to understand the configuration situation of the measurement interval by the base station, so as to avoid problems such as possible resource waste caused by multiple positioning base stations participating in the positioning still sending downlink positioning reference signals according to the previous configuration with a large bandwidth or overhead, and ensure the smooth progress of the measurement of the downlink positioning reference signal.
[0059] As Figure 3 shown, it is a schematic flowchart of a measurement interval configuration request method 300 provided by an exemplary embodiment of the present application. This method 300 can be applied to a base station and can be specifically executed by hardware or software in the base station. Referring again to Figure 3 , method 300 may at least include the following steps.
[0060] S310, receive a measurement interval request sent by the terminal and / or the location server.
[0061] Among them, in addition to referring to the detailed description in the foregoing S210 for the relevant process of S310, in a possible implementation manner, the measurement interval request may include at least one of the following contents.
[0062] (1) Interval confirmation information: used to instruct the base station to confirm whether the measurement interval can be configured. In one implementation manner, the interval confirmation information can also be used to instruct the base station to feedback the confirmation result of whether the measurement interval can be configured, etc.
[0063] (2) Interval feedback information: used to indicate whether the base station can configure the measurement interval to the terminal and / or the location server. For example, the base station can feedback information to the terminal and / or the location server to indicate whether the base station configures the measurement interval.
[0064] (3) Interval request: used to indicate to the base station that the terminal will use the measurement interval to measure the downlink positioning reference signal.
[0065] (4) Measurement frequency point information: used to indicate the frequency point information when the terminal uses the measurement interval to perform downlink positioning reference signal measurement. For example, the measurement frequency point information can be but is not limited to absolute frequency point position information, etc.
[0066] (5) Requested measurement interval configuration information: used to implement the measurement of the downlink positioning reference signal. Optionally, the measurement interval configuration information can at least include at least one of gap pattern ID, gap offset, gap period, gap duration, gap TA.
[0067] Exemplarily, the measurement interval configuration information can be but is not limited to that shown in Table 1 below. For example, the gap period can be but is not limited to 20ms, 40ms, 80ms, 160ms, etc., and the gap duration can be 1.5ms, 3ms, 3.5ms, 4ms, 5.5ms, 6ms, etc.
[0068] (6) Start time of the measurement interval: The start time of the measurement interval refers to the time point at which the measurement interval becomes effective at or after a certain time point. For example, for on demand PRS configuration, the location server will configure the on demand PRS effective time. To match the on demand PRS effective time, the location server can indicate the effective time of the measurement interval to the base station, such as the start effective time of the measurement interval, the effective duration of the measurement interval, the cut-off time of the measurement interval, etc.
[0069] (7) Cut-off time of the measurement interval: The cut-off time of the measurement interval refers to the time point at which the measurement interval stops working / fails at or before a certain time point, which can be combined with the description in (6) above.
[0070] (8) Effective duration of the measurement interval: The effective duration of the measurement interval refers to the effective duration of the measurement interval, which can be combined with the description in (6) above.
[0071] (9) At least partial configuration information of the downlink positioning reference signal: The at least partial configuration information of the downlink positioning reference signal refers to the configuration information associated with the measurement interval, or the configuration information when the terminal expects to perform measurements during the measurement interval, which is used to assist the base station in determining how to configure the measurement interval.
[0072] In practical applications, according to the different types of the downlink positioning reference signal, the information included in the at least partial configuration information is different. For example, when the downlink positioning reference signal is PRS, the at least partial configuration information may include PRS frequency-domain position information (such as Frequency Layer information, band information, start position information, etc.), time-domain position information (such as PRS period, offset, duration, etc.), or the at least partial configuration information may further include the PRS identification information, etc.
[0073] Table 1
[0074]
[0075] Among them, the PRS identification (ID) information may include at least one of Positioning Frequency Layer ID, Transmission and Reception Point (TRP) ID, PRS resource set ID, PRS resource ID, band ID. Optionally, the Positioning Frequency Layer ID may be the Positioning Frequency Layer ID configured by the location server, or the ID of the terminal when sending the measurement interval request. For example, if the terminal requests a measurement interval for 4 Positioning Frequency Layers, the ID of the Positioning Frequency Layer may be 0, 1, 2, 3.
[0076] (10) Priority information (i.e., importance), which is used to indicate the priority of performing downlink positioning reference signal measurement or location service in the measurement interval, so as to assist the base station in confirming whether to configure the measurement interval and how to perform subsequent actions. For example, if the priority of performing downlink positioning reference signal measurement in the measurement interval is high, the base station will interrupt other services such as the physical downlink shared channel (PDSCH) and configure the measurement interval for downlink positioning reference signal measurement. In actual applications, the priority (or importance) can be divided into multiple levels (such as 0, 1, 2, 3..., 0 represents the highest level), and the terminal or the location server can indicate the priority (or importance) as any one of the aforementioned multiple levels.
[0077] It should be noted that the priority (or importance) of performing downlink positioning reference signal measurement in the measurement interval can be indicated by the location server or determined by the terminal or pre-configured or agreed upon by protocol. For example, when determined by the terminal, the terminal can determine it based on the received positioning request information such as QoS, and this embodiment does not impose any restrictions on this.
[0078] (11) bandwidth part BWP activation information, used to instruct the base station to activate the BWP when it is determined that the measurement interval cannot be configured, so as to perform the measurement of the downlink positioning reference signal in the activated BWP. Optionally, the BWP activation information may also include at least BWP configuration information expected by the terminal, such as BWP identification information, BWP frequency domain location information, etc.
[0079] As an implementation manner, when the base station determines not to configure the measurement interval, the base station may switch the current active DL BWP of the terminal to a target BWP, such as a new BWP or a positioning BWP, or the base station directly activates the target BWP, such as a new BWP or a positioning BWP. The positioning BWP is a BWP dedicated to positioning.
[0080] It should be noted that the measurement interval request may include one or more combinations of the above, and may also include other information in addition to the above eleven types of information, etc., and this embodiment does not limit this.
[0081] In addition, since the terminal can request a corresponding measurement interval for each Frequency Layer, each Frequency Layer can correspond to a set of parameters. Each set of parameters can at least include interval confirmation information, interval feedback information, interval request, measurement frequency point information, requested measurement interval configuration information, start time of the measurement interval, cut-off time of the measurement interval, effective duration of the measurement interval, at least partial configuration information of the downlink positioning reference signal, priority information, bandwidth part BWP activation information, etc. Among them, the interval confirmation information, interval feedback information, interval request, start time of the measurement interval, cut-off time of the measurement interval, effective duration of the measurement interval, priority information, and bandwidth part BWP activation information can be configured for each Frequency Layer or can be common parameters for multiple Frequency Layers. This embodiment does not limit this.
[0082] In the above possible implementation, the terminal or the location server interacts more useful information with the base station, so that the base station can obtain more useful information, increasing the possibility of the base station configuring the measurement interval and avoiding the positioning service not meeting the requirements due to the configuration problem of the measurement interval.
[0083] S320. The feedback information is used to indicate whether the base station configures a measurement interval for downlink positioning reference signal measurement.
[0084] Among them, the relevant description in S320, in addition to referring to the detailed description in the foregoing S220, is again referred to Figure 3 As shown, as a possible implementation, sending the feedback information to the terminal and / or the location server in S320 includes the following steps.
[0085] S3201. If the measurement interval configuration is not configured, send the feedback information to the terminal and / or the location server. Among them, the feedback information indicates that the base station does not configure the measurement interval. In practical applications, the actual content of the feedback information can be set according to requirements. For example, the feedback information can include at least one of the following:
[0086] (1) Downlink positioning reference signal identifier for which the measurement interval is not configured: Among them, according to the differences in the downlink positioning reference signal, the downlink positioning reference signal identifier is different. For example, the downlink positioning reference signal identifier can include a positioning frequency layer identifier, used to indicate which measurement intervals associated with the positioning frequency layer are not configured, or can include at least one of the TRP ID, PRS resource set ID, and PRS resource ID, used to indicate which measurement intervals associated with the positioning reference signal are not configured.
[0087] (2) Do not configure the configuration information of the measurement interval, which is used to indicate which of the requested measurement intervals is / are not configured. Optionally, the configuration information at least includes at least one of the frequency point information for performing measurements, interval mode identifier, interval offset, interval period, interval duration, and interval timing advance.
[0088] (3) At least part of the downlink BWP configuration information: It is used to indicate the range within the current carrier of the location server or / and the terminal where the terminal can perform downlink positioning reference signal measurements, etc.
[0089] Optionally, at least part of the configuration information in the downlink BWP configuration information may include active and / or inactive DL BWP configuration information within one or more carriers (such as including but not limited to at least one of frequency domain position, bandwidth, BWP timer, BWP identifier, subcarrier spacing, etc.), and the configuration information of the carrier where the BWP is located (such as including but not limited to at least one of carrier frequency domain position, bandwidth, identifier, etc. information).
[0090] (4) Recommended measurement interval configuration information: It is used to indicate the measurement interval configuration that the base station recommends more to the location server or / and the terminal compared to the requested measurement interval. Optionally, the measurement interval configuration information can be determined by the base station by synthesizing the measurement interval requests of one or more of the location servers and / or terminals.
[0091] (5) Recommended downlink positioning reference signal configuration information: The recommended downlink positioning reference signal configuration information can be determined by the base station by synthesizing the measurement interval requests of one or more of the location servers and / or terminals.
[0092] (6) BWP activation request indication signaling, which is used to indicate or trigger the terminal to initiate the BWP activation process and perform downlink positioning reference signal measurements in the newly activated BWP. Among them, the BWP activation request indication signaling is also used to indicate the configuration information of the activated BWP.
[0093] (7) The reason for not configuring the measurement interval. Optionally, the reason for not configuring the measurement interval may include excessive overhead, time domain channel not available for occupancy, frequency domain channel not available for occupancy, the current serving cell interval not being supported, etc.
[0094] It should be noted that the non - support of the current serving cell interval mentioned above means that for multiple terminals belonging to the same base station, and when the measurement interval configurations requested by these multiple terminals are all rejected by the base station, then the base station can feedback to the location server or / and the terminal the information including that the current serving cell interval is not supported.
[0095] S3202, if the measurement interval is configured, send the feedback information to the terminal and / or the location server.
[0096] Wherein, the feedback information indicates that the base station configures the measurement interval. Optionally, the feedback information may include configuration information of the measurement interval configured by the base station, etc., and this embodiment does not limit this.
[0097] Further, as another possible implementation manner of this embodiment, if the base station does not configure the measurement interval, it triggers a BWP activation process and sends a target BWP activation signaling to the terminal.
[0098] Wherein, the target BWP may be a dedicated positioning BWP or a certain BWP other than the currently activated downlink BWP of the terminal, for the terminal to perform measurement of the downlink positioning reference signal in the target BWP.
[0099] In addition, the target BWP activation signaling may at least include configuration information for activating the BWP, such as BWP identification information, etc. When the measurement interval is unavailable, the terminal can switch to the target BWP to perform measurement of the downlink positioning reference signal. Wherein, the target BWP may be configured by the network, pre-configured or agreed upon by the protocol.
[0100] In the measurement interval configuration method 300 given in this embodiment, the base station determines how to configure the measurement interval and whether to configure the measurement interval according to the measurement interval request, which can effectively avoid the problem of not meeting the positioning requirements or resource waste caused by the configuration problem of the measurement interval, and can meet the different positioning requirements of different terminals.
[0101] It should be noted that for the measurement interval configuration request methods 200 and 300 provided in the embodiments of the present application, the execution subject may be a measurement interval configuration request device, or a control module in the measurement interval configuration request device for executing the measurement interval configuration request methods 200 or 300.
[0102] As Figure 4 shown, it is a flowchart of a measurement interval configuration request method 400 provided by an exemplary embodiment of the present application. This method 400 can be applied to a location server and can be specifically executed by hardware or software in the location server. Referring again to Figure 4 , method 400 may at least include the following steps.
[0103] S410, send a preset signaling to the terminal.
[0104] Among them, the preset signaling includes at least part of the information in the current downlink positioning reference signal configuration information, so as to enable the terminal to determine whether a measurement interval is required according to the at least part of the information. The configuration information of the downlink positioning reference signal can also be expressed as the auxiliary information of the downlink positioning reference signal. In practical applications, the actual content included in the at least part of the information can be flexibly set according to requirements.
[0105] S420, send a measurement interval request to the base station of the terminal.
[0106] Among them, the measurement interval request is used to instruct the base station to configure a measurement interval for downlink positioning reference signal measurement, and / or the measurement interval request is used to instruct the base station to feedback to the terminal and / or the location server whether the measurement interval can be configured.
[0107] In practical applications, the location server may send the measurement interval request to the base station when the location server itself determines that the terminal needs measurement interval configuration, or when the location server sends the measurement interval request according to the information fed back by the terminal indicating the need for measurement interval configuration. This embodiment does not limit this.
[0108] In addition, the related descriptions of the downlink positioning reference signal and the data transmission method between the location server and the base station can refer to the detailed descriptions of the foregoing S210 and S220, and are not elaborated herein in this embodiment.
[0109] In the measurement interval configuration request method provided in this embodiment, the location server sends a measurement interval request to the base station of the terminal, so that the base station determines and feedbacks whether to configure the measurement interval, so that the location server and / or the terminal can understand the configuration of the measurement interval by the base station, thereby avoiding problems such as resource waste that may be caused by multiple positioning base stations participating in positioning still sending downlink positioning reference signals according to the previous configuration with a larger bandwidth or overhead.
[0110] As Figure 5 shown, it is a schematic flowchart of a measurement interval configuration request method 500 provided by an exemplary embodiment of the present application. The method 500 can be applied to a location server and can be specifically executed by hardware or software in the location server. Referring again to Figure 5 , the method 500 may at least include the following steps.
[0111] S510, send a preset signaling to the terminal.
[0112] Among them, in addition to referring to the detailed description of S410 above, the preset signaling can also be used to request the terminal to determine whether to request the measurement interval, and / or, the preset signaling is used to request at least one of the configuration information of the measurement interval expected by the terminal, the frequency points for performing measurements, and the downlink positioning reference signal identification information associated with the measurement interval. Thus, it can be used to implement information exchange between the location server and the terminal, enabling the terminal and / or the location server to more accurately determine whether measurement interval configuration is required, and enabling the location server to determine how to perform subsequent operations.
[0113] S520, send a measurement interval request to the base station of the terminal.
[0114] Among them, in addition to referring to the relevant description in S420 above, as a possible implementation, the measurement interval request may include at least one of the following:
[0115] (1) Interval confirmation information, used to indicate whether the base station can configure the measurement interval.
[0116] (2) Interval feedback information, used to indicate whether the base station can configure the measurement interval and feedback it to the terminal and / or the location server.
[0117] (3) Interval request, used to indicate to the base station that the terminal will use the measurement interval to measure the downlink positioning reference signal.
[0118] (4) Measurement frequency point information, used to indicate the frequency point information when the terminal uses the measurement interval to perform measurements.
[0119] (5) Requested measurement interval configuration information.
[0120] (6) Start time of the measurement interval.
[0121] (7) Cut-off time of the measurement interval.
[0122] (8) Effective duration of the measurement interval.
[0123] (9) At least partial configuration information of the downlink positioning reference signal.
[0124] (10) Priority information, used to indicate the priority of measuring the downlink positioning reference signal or providing location services during the measurement interval.
[0125] (11) Bandwidth part BWP activation information, used to indicate that when the base station determines that it cannot configure the measurement interval, it activates the BWP to perform the measurement of the downlink positioning reference signal in the activated BWP.
[0126] It should be noted that for the detailed content of the foregoing information included in the measurement interval request, reference may be made to the detailed description in the foregoing S310, and details are not described herein again in this embodiment.
[0127] S530, receive the feedback information sent by the base station, and / or receive the feedback information forwarded by the terminal.
[0128] Wherein, the feedback information is used to indicate whether the base station configures the measurement interval. Optionally, if the feedback information received by the location server indicates that the base station does not configure the measurement interval, the feedback information may include at least one of the following:
[0129] (1) The identifier of the downlink positioning reference signal for which the measurement interval is not configured.
[0130] (2) The configuration information for which the measurement interval is not configured.
[0131] (3) At least part of the information in the downlink BWP configuration information.
[0132] (4) The recommended measurement interval configuration information.
[0133] (5) The recommended downlink positioning reference signal configuration information.
[0134] (6) The BWP activation request indication signaling, which is used to indicate or trigger the terminal to initiate the BWP activation process and perform the measurement of the downlink positioning reference signal in the newly activated BWP.
[0135] (7) The reason for not configuring the measurement interval.
[0136] It should be noted that for the detailed content of the foregoing information included in the feedback information, reference may be made to the detailed description in the foregoing S320, and details are not described herein again in this embodiment.
[0137] In addition, as a possible implementation manner, in order to determine the measurement parameters of the new downlink positioning reference signal for the terminal and ensure the smooth progress of the measurement, when the feedback information received by the location server indicates that the base station does not configure the measurement interval, the location server may also perform at least one of the following:
[0138] (1) Determine the new downlink positioning reference signal configuration information to match the requirements of the base station.
[0139] Wherein, the new downlink positioning reference signal configuration information includes: the downlink positioning reference signal configuration information before the current downlink positioning reference signal configuration information of the terminal, or the downlink positioning reference signal configuration information obtained by updating (or modifying) the current downlink positioning reference signal configuration information according to the feedback information, or restoring the current demand-based downlink reference signal configuration to a conventional downlink reference signal configuration, etc.
[0140] It should be noted that updating the downlink positioning reference signal configuration information may be to restore the configuration of the Positioning Frequency Layer before the recovery measurement interval request is rejected. Correspondingly, when the location server sends the PRS configuration to the terminal and / or the base station participating in the positioning service, it may be to send the restored previous configuration of the Frequency Layer.
[0141] In practical applications, taking the downlink positioning reference signal as PRS as an example, determining the new downlink positioning reference signal configuration information may include: increasing, decreasing, or changing the PRS configuration according to the feedback information, including but not limited to at least one of the PRS bandwidth, increasing the PRS period (duration), decreasing the PRS period, increasing the Frequency Layer, etc., so as to match the requirements of the base station. Or, determining the new downlink positioning reference signal configuration information may further include: restoring the current demand-based downlink reference signal configuration to a conventional downlink reference signal configuration, restoring the reference signal configuration modified for on demand positioning to the conventional configuration before modification (for example, if the on demand positioning increases the PRS bandwidth on the basis of the original PRS configuration, then the terminal needs to request a measurement interval to perform PRS measurement after the bandwidth is increased, but this measurement interval is rejected by the base station. At this time, the location server can restore the bandwidth modified by the on demand PRS to the conventional bandwidth before modification). This embodiment does not limit this. Here, the aforementioned new downlink positioning reference signal configuration can also be understood as updated, modified, restored, etc. Optionally, in some cases, the conventional configuration may mean not sending a positioning reference signal.
[0142] In addition, when determining the new downlink positioning reference signal configuration information, the location server may also determine one or more positioning base stations participating in the positioning service and located around the terminal.
[0143] (2) Send the new downlink positioning reference signal configuration information to the terminal and / or the positioning base station participating in the downlink positioning reference signal positioning service.
[0144] Among them, the new downlink positioning reference signal configuration information can be sent to the terminal through signaling such as LPP, and the new downlink positioning reference signal configuration information can be sent to each positioning base station through signaling such as LPPa. Correspondingly, each positioning base station sends a downlink positioning reference signal to the terminal according to the received new downlink positioning reference signal configuration information, and the terminal measures the downlink positioning reference signal according to the downlink positioning reference signals sent by each positioning base station received and the downlink positioning reference signal configuration information sent by the location server.
[0145] It should be noted that in the conventional downlink reference signal configuration scenario, the location server may not send the conventional downlink reference signal configuration to the terminal or the positioning base station.
[0146] (3) Adjust the preset positioning requirement and / or the performance index of the terminal, and send the adjusted positioning requirement and / or the performance index of the terminal to the upper-layer network node.
[0147] Among them, the upper-layer network node may be a core network node or the like, and this embodiment does not limit this.
[0148] (4) Send an indication information that the preset positioning requirement cannot be met and the reason why the preset positioning requirement cannot be met to the upper-layer network node.
[0149] Among them, the reason why the preset positioning requirement cannot be met can be set according to the actual situation. For example, it can be that the base station does not configure the measurement interval, does not receive the measurement interval configuration feedback from the base station, the positioning base station signal transmission fails, etc.
[0150] (5) Send a BWP activation request to the base station. Optionally, at least the BWP configuration information expected by the terminal is included in the BWP activation request, such as the BWP identifier expected by the terminal.
[0151] As another possible implementation manner, if the feedback information received by the location server indicates that the base station configures the measurement interval, the current downlink positioning reference signal configuration information or other information in the current downlink positioning reference signal configuration information except the at least partial information is sent to the terminal and / or the positioning base stations participating in the downlink positioning reference signal positioning service, so that the terminal performs corresponding measurements based on the received downlink positioning reference signals to ensure the smooth progress of the measurement process.
[0152] As Figure 6 shown, it is a flowchart of a measurement interval configuration request method 600 provided by an exemplary embodiment of the present application. The method 600 can be applied to a location server and can be specifically executed by hardware or software in the location server. Referring again to Figure 6, Method 600 may at least include the following steps.
[0153] S610, Receive a demand-based positioning request for the terminal.
[0154] Among them, in this embodiment, a demand-based positioning request is adopted, which can flexibly increase or decrease the downlink positioning reference signal configuration according to the positioning requirements of one or more terminals. For example, if the pre-deployed downlink positioning reference signal is a downlink positioning reference signal with a small bandwidth, and for a terminal with a relatively high positioning accuracy requirement, a dedicated downlink positioning reference signal with a large bandwidth can be configured for this terminal through signaling. Thus, while meeting the requirements of terminals with high positioning accuracy, the problem of resource waste that may occur due to some terminals with low positioning accuracy requirements can be avoided, effectively meeting the positioning requirements of different terminals.
[0155] In practical applications, the positioning request may also be sent by a core network node or other network nodes. At the same time, in addition to the demand-based positioning request, it may also be a conventional positioning request. For specific details, reference may be made to the description in S210 above. This embodiment does not limit this.
[0156] S620, Obtain the capability information of the terminal.
[0157] Among them, when the location server obtains the capability information of the terminal, it can be realized by sending a capability information acquisition signaling to the terminal, etc. Optionally, the capability information of the terminal may be, but is not limited to, the maximum supported downlink positioning reference signal (such as PRS) configuration of the terminal, the capability of the terminal to process the downlink positioning reference signal, etc.
[0158] S630, Determine the current downlink positioning reference signal configuration information of the terminal based on the capability information of the terminal and / or the demand-based positioning request of the terminal.
[0159] S640, Determine the measurement interval configuration required for the terminal to measure the target positioning service.
[0160] Among them, the target positioning service is the positioning service corresponding to the current downlink positioning reference signal configuration information. There are various ways to determine the measurement interval configuration. For example, as a possible implementation, the implementation process of S640 may include: receiving the BWP configuration information (such as BWP frequency domain position information) of the terminal sent by the terminal and / or the base station; determining the measurement interval required for the terminal to measure the positioning service corresponding to the current downlink positioning reference signal configuration information according to the BWP configuration information and the current downlink positioning reference signal configuration information.
[0161] Optionally, the BWP configuration information at least includes the configuration information of active and / or inactive DL BWPs (which can also be understood as serving cells) within one or more carriers (for example, including but not limited to at least one of frequency domain position, bandwidth, BWP timer, BWP identifier, subcarrier spacing, etc.), and the configuration information of the carrier where the BWP is located (for example, including but not limited to at least one of carrier frequency domain position, bandwidth, identifier, etc.). This embodiment does not limit this.
[0162] S650, send a preset signaling to the terminal.
[0163] Among them, the relevant description of S650 can refer to the detailed description of the foregoing S510, and this embodiment will not repeat it here.
[0164] S660, receive the feedback indication returned by the terminal.
[0165] Among them, the feedback indication is used to indicate whether the terminal has requested the measurement interval and / or the reason why the terminal has requested the measurement interval. Optionally, the reason for requesting the measurement interval may be at least one of the preset positioning requirements not being met due to not performing positioning measurements in the measurement interval, the active BWP bandwidth being insufficient, the active BWP numerology being different from the PRS configuration, etc. The reason for not requesting the measurement interval may be that according to the current downlink positioning reference signal configuration information, even if the measurement interval is not requested, the preset positioning requirements can still be met, etc.
[0166] In practical applications, if the feedback indication indicates that the terminal has requested the measurement interval, the location server may wait for the feedback signaling from the terminal or the base station on whether the measurement interval has been configured, and determine to perform subsequent operations according to the feedback signaling. On the contrary, if the feedback indication indicates that the terminal has not requested the measurement interval, the location server can simply perform the subsequent positioning steps (in the case of not requesting the measurement interval, the location server can assume that based on the current PRS configuration, the terminal can meet the measurement accuracy requirements).
[0167] In addition, if the location server does not receive the feedback indication, it can be determined that the terminal has not requested the measurement interval, or the terminal does not require the measurement interval configuration, which can be specifically set according to actual requirements.
[0168] Optionally, the feedback indication may further include whether the terminal needs to request the measurement interval and / or the measurement interval configuration expected by the terminal. If the terminal feedbacks that it needs to request the measurement interval, the location server can execute the relevant steps in S670.
[0169] S670, send a measurement interval request to the base station of the terminal.
[0170] Among them, for the relevant description of S670, reference can be made to the detailed description of the foregoing S520, and this embodiment will not be elaborated herein.
[0171] It should be noted that in the measurement interval configuration request method 600 given above, the process of the location server executing the measurement interval configuration request may be, but is not limited to, the order in S610 - S670 above, and the process of executing the measurement interval configuration request may have more or fewer steps than the foregoing. For example, before the location server executes S650, it may execute at least one of the following:
[0172] (1) When receiving a demand - based positioning request for the terminal, obtain the capability information of the terminal.
[0173] (2) Based on the capability information of the terminal and / or the demand - based positioning request, determine the current downlink positioning reference signal configuration information of the terminal.
[0174] (3) Determine the measurement interval configuration required by the terminal to measure the target positioning service.
[0175] For the description of the relevant embodiments of (1) - (3), reference can be made to the embodiments of the foregoing base station, so it will not be elaborated herein.
[0176] In addition, for the measurement interval configuration request methods 400 - 600 provided in the embodiments of the present application, the execution subject may be a measurement interval configuration request device, or a control module in the measurement interval configuration request device for executing the measurement interval configuration request methods 400 - 600. In the embodiments of the present application, taking the measurement interval configuration request device as an example to execute the measurement interval configuration request method, the measurement interval configuration request device provided in the embodiments of the present application is described.
[0177] As Figure 7 shown, it is a schematic flowchart of a measurement interval configuration request method 700 provided in an exemplary embodiment of the present application. This method 700 can be applied to a terminal and can be specifically executed by hardware or software in the terminal. Referring again to Figure 7 , method 700 may at least include the following steps.
[0178] S710, receive a preset signaling sent by a location server.
[0179] Among them, the preset signaling includes at least part of the information in the current downlink positioning reference signal configuration information, and is used to determine whether a measurement interval configuration is required.
[0180] S720, according to the preset signaling, send a measurement interval gap request to a base station.
[0181] Among them, the measurement interval request is used to instruct the base station to configure the measurement interval for downlink positioning reference signal measurement.
[0182] S730. Perform the measurement of the downlink positioning reference signal according to whether the measurement interval is configured and / or the preset signaling.
[0183] Among them, when the terminal performs the measurement of the downlink positioning reference signal, each positioning base station participating in the positioning measurement determined by the location server can activate the UL BWP to send the downlink positioning reference signal to the terminal according to the received downlink positioning reference signal configuration information, so that the terminal can perform the positioning measurement based on the received downlink positioning reference signal.
[0184] In addition, it should be noted that the relevant processes in S710 - S730 can refer to the detailed description in the measurement interval configuration request 400 - 600. To avoid repetition, they will not be elaborated here.
[0185] In the foregoing measurement method provided in this embodiment, the terminal sends a measurement interval request to the location server, and then performs the measurement of the downlink positioning reference signal according to the measurement interval and / or the preset signaling, thereby avoiding problems such as possible resource waste caused by multiple positioning base stations participating in the positioning still sending downlink positioning reference signals according to the previous larger bandwidth or overhead configuration, and ensuring the smooth progress of the downlink positioning reference signal measurement.
[0186] As Figure 8 shown, it is a schematic flowchart of a measurement interval configuration request method 800 provided by an exemplary embodiment of the present application. This method 800 can be applied to a terminal and can be specifically executed by hardware or software in the terminal. Referring again to Figure 8 , the method 800 may at least include the following steps.
[0187] S810. Receive the preset signaling sent by the location server.
[0188] As a possible implementation manner, the preset signaling is further used to request the terminal to feedback whether it requests the measurement interval, and / or, the preset signaling is used to request at least one of the configuration information of the measurement interval expected by the terminal, the frequency point information for performing the measurement, and the downlink positioning reference signal identification information associated with the measurement interval.
[0189] In practical applications, after the terminal receives the preset signaling from the location server, the terminal may send a feedback indication to the location server, where the feedback indication is used to indicate whether the terminal requests the measurement interval. In addition, according to the difference of the preset signaling, the feedback indication may further be used to indicate at least one of the following:
[0190] (1) Whether the terminal sends the measurement interval request to the base station.
[0191] (2) The reason why the terminal sends the measurement interval request to the base station.
[0192] Among them, the reason for sending the measurement interval request may be at least one of information such as the preset positioning requirement cannot be met, the active BWP bandwidth is insufficient, and the active BWP numerology is different from the PRS configuration. Correspondingly, the reason for not sending the measurement interval request may be that the preset positioning requirement can be met, etc.
[0193] (3) The downlink positioning reference signal identifier associated with the measurement interval request.
[0194] Among them, regarding the downlink positioning reference signal identifier, reference may be made to the detailed description in the foregoing S3201, and this embodiment will not elaborate here.
[0195] S820. Send a measurement interval request to the base station according to the preset signaling.
[0196] Among them, the measurement interval request includes at least one of the following:
[0197] (1) Interval confirmation information, used to indicate whether the base station can configure the measurement interval.
[0198] (2) Interval feedback information, used to indicate whether the base station can configure the measurement interval and feedback to the terminal and / or the location server.
[0199] (3) Interval request, used to indicate to the base station that the terminal will use the measurement interval to measure the downlink positioning reference signal.
[0200] (4) Measurement frequency point information, used to indicate the frequency point information when the terminal uses the measurement interval to perform measurements.
[0201] (5) Requested measurement interval configuration information.
[0202] (6) The start time of the measurement interval.
[0203] (7) The end time of the measurement interval.
[0204] (8) The effective duration of the measurement interval.
[0205] (9) At least partial configuration information of the downlink positioning reference signal.
[0206] (10) Priority information, used to indicate the priority of measuring the downlink positioning reference signal or providing location services during the measurement interval.
[0207] (11) Bandwidth Part (BWP) activation information, which is used to indicate that when the base station determines that the measurement interval cannot be configured, BWP activation is performed to execute the measurement of the downlink positioning reference signal in the activated BWP.
[0208] It should be noted that for the detailed content of the foregoing information included in the measurement interval request, reference may be made to the detailed description in the foregoing S310, and this embodiment will not elaborate herein.
[0209] S830: Receive the feedback information sent by the base station.
[0210] Among them, if the feedback information indicates that the base station configures the measurement interval, then S840 to S850 are executed; otherwise, the preset operation in S860 is executed.
[0211] In addition, as a possible implementation manner, if the feedback information indicates that the base station does not configure the measurement interval, then the feedback information may include at least one of the following:
[0212] (1) Downlink positioning reference signal identifier for which the measurement interval is not configured.
[0213] (2) Configuration information for which the measurement interval is not configured.
[0214] (3) At least partial information in the downlink BWP configuration information.
[0215] (4) Recommended measurement interval configuration information.
[0216] (5) Recommended downlink positioning reference signal configuration information.
[0217] (6) BWP activation request indication signaling, which is used to indicate or trigger the terminal to initiate a BWP activation process and execute the measurement of the downlink positioning reference signal in the newly activated BWP.
[0218] Among them, when the BWP activation request indication signaling indicates that the base station triggers a BWP handover, switch to the target BWP, where the target BWP is the positioning BWP or a new BWP other than the downlink BWP currently activated by the terminal.
[0219] (7) Reason for not configuring the measurement interval.
[0220] It should be noted that for the detailed content of the foregoing information included in the feedback information, reference may be made to the detailed description in the foregoing S320, and this embodiment will not elaborate herein.
[0221] S840. Perform the measurement of the downlink positioning reference signal according to whether the measurement interval is configured and / or the preset signaling.
[0222] S850. Send the measurement result of the downlink positioning reference signal to the location server.
[0223] Wherein, the measurement result of the downlink positioning reference signal includes at least one of the following information:
[0224] (1) The measurement result of the downlink positioning reference signal. Wherein, the measurement result is an estimated value of the positioning measurement result.
[0225] (2) Whether the measurement of the downlink positioning reference signal is performed during the measurement interval.
[0226] Optionally, performing the measurement of the downlink positioning reference signal during the measurement interval may implicitly indicate that the measurement interval request has been sent to the base station; conversely, not performing the measurement of the downlink positioning reference signal during the measurement interval may implicitly indicate that the measurement interval request has been sent to the base station, but the measurement interval is not configured.
[0227] In addition, if the measurement of the downlink positioning reference signal is performed during the measurement interval, the terminal may also send the specific information of the downlink positioning reference signal measured during the measurement interval. For example, the type of the downlink positioning reference signal, the measurement bandwidth, the measured Frequency Layer, the measured PRS resource, the measured PRS resourceset, the measured TRP identifier, etc. Or, the terminal may also send the identifiers corresponding to the foregoing information, such as FrequencyLayer id, trp id, PRS resource set id, resource id, band id, etc.
[0228] Of course, if the measurement of the positioning reference signal is not performed during the measurement interval, the specific information of the corresponding positioning reference signal may also be sent. Reference may be made to the above embodiments, and this embodiment will not be elaborated herein.
[0229] (3) Whether the measurement interval request has been sent to the base station. Optionally, the specific information of the corresponding positioning reference signal may also be sent in the information of whether to request the measurement interval. Reference may be made to the above.
[0230] Wherein, as a possible implementation manner, when implementing the sending of (1), the terminal may not send any information to implicitly indicate whether the terminal has sent the measurement interval request.
[0231] In addition, if the terminal sends a measurement interval request, then, which downlink positioning reference signals (such as PRS) has the terminal not requested measurement interval configuration, such as the identifier of the downlink positioning reference signal that does not request measurement interval configuration, can also be sent.
[0232] (4) Associated downlink positioning reference signal identifier.
[0233] As an implementation, when the terminal sends the information in the above (1)-(4), it can be sent in the form of 0 / 1 bits.
[0234] Optionally, whether the terminal performs PRS measurement through the measurement interval and / or whether it requests measurement interval configuration can also be in the following ways:
[0235] The terminal only sends which positioning reference signals request the measurement interval but do not perform measurements in the measurement interval. Among them, the specific information of the positioning reference signal can refer to the corresponding description in the foregoing embodiments. For example, for a certain measurement result, bit '1' indicates that the measurement result is after requesting the measurement interval but not performing measurements in the measurement interval, and bit '0' indicates that the measurement result is after requesting the measurement interval and performing measurements in the measurement interval or not requesting the measurement interval. Based on this information, the network device can expect which PRS measurement results can definitely meet the positioning requirements.
[0236] S860, perform a predetermined operation, and the predetermined operation includes at least one of the following:
[0237] (1) Send a BWP activation request to the base station for requesting to perform measurement of the downlink positioning reference signal in a newly activated BWP.
[0238] (2) Send a BWP activation request confirmation signaling to the location server, where the BWP activation request confirmation signaling is used to indicate whether the terminal sends the BWP activation request to the base station.
[0239] Among them, through the setting of S860, when the base station does not configure the measurement interval, the terminal can perform measurement of the downlink positioning reference signal in a newly activated BWP, so as to realize the normal measurement of the downlink positioning reference signal and ensure the accuracy of the measurement result.
[0240] It should be noted that in the above-mentioned measurement method, after sending a measurement interval gap request to the base station, if the measurement interval is not configured, the terminal is not required and / or expected to process the downlink positioning reference signal. Alternatively, only when the terminal requests the measurement interval request and the measurement interval is not configured, the terminal is not required / expected to process the downlink positioning reference signal. That is, when the terminal does not request the measurement interval, the terminal is required / expected to process the downlink positioning reference signal and / or when the terminal requests a measurement interval and the measurement interval is configured, the terminal is required / expected to process the downlink positioning reference signal. Optionally, in English, it can be expressed as "UE is not expected / required to process DL PRS only if the measurement gap requested by the UE and the gap is not configured".
