[0035] In the above embodiment, the terminal itself determines the PRS or PRS set for bandwidth aggregation to obtain which PRS or PRS sets used for bandwidth aggregation can be used for transmission during positioning measurement, thereby increasing the transmission opportunity for subsequent PRS transmission after bandwidth aggregation.

[0036] In combination with some embodiments of the first aspect, in some embodiments, the method further includes: receiving first information, the first information being used to indicate the PRS or PRS set for which bandwidth aggregation is desired; determining the PRS or PRS set for which bandwidth aggregation is desired in the positioning measurement, including: determining the PRS or PRS set for which bandwidth aggregation is desired in the positioning measurement based on the PRS or PRS set for which bandwidth aggregation is desired.

[0037] In the above embodiment, the terminal can determine the PRS or PRS set that can actually be used for bandwidth aggregation in the PRS or PRS set for bandwidth aggregation pre-configured by the network through the configuration information sent by the network device, thereby avoiding the situation in which the PRS or PRS set that cannot be used for transmission exists in the PRS or PRS set for bandwidth aggregation pre-configured by the network during subsequent aggregation.

[0127] In some embodiments, the network device 102 may include at least one of an access network device and a core network device.

[0128] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a wireless fidelity (WiFi) system, but is not limited thereto.

[0130] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0131] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0132] In some embodiments, the core network device may be a device including one or more network elements, or may be multiple devices or a group of devices including one or more network elements, or may be physical. The core network may include, for example, at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

[0133] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0134] [Corrected 22.05.2023 in accordance with Rule 91] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto. The entities shown in FIG1a are illustrative only. The communication system may include all or part of the entities shown in FIG1a, or may include other entities other than those shown in FIG1a. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0135] The embodiments of the present disclosure can be applied to long term evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, ultra mobile broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE802.20, ultra-wideband (UWB), Bluetooth (registered trademark)), public land mobile network (PLMN) network, device-to-device (D2D) system, machine-to-machine (M2M) system, Internet of Things (IoT) system, vehicle-to-everything (V2X), systems using other positioning measurement methods, and next-generation systems based on these. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A with 5G, etc.) for application.

[0136] In the embodiment of the present disclosure, the terminal performs positioning measurement based on a reference signal, for example, performs positioning measurement based on a PRS.

[0137] [Corrected 22.05.2023 according to Rule 91] Figure 1b shows a schematic diagram of a PRS configuration shown in an exemplary embodiment of the present disclosure. Referring to Figure 1b, the network device configures multiple positioning frequency layers (PFLs) for the terminal, such as PFL1 and PFL2 in Figure 1b. Among them, each of the multiple PFLs will be configured with one or more PRSs / PRSs or PRS sets (PRS sets) for each transmission reception point (TRP). For example, in Figure 1b, PRS set1 and PRS set2 are configured for TRP1 and TRP2 respectively in PFL1. PRS set3 and PRS set4 are configured for TRP1 and TRP2 respectively in PFL2. Among them, the PRSs configured in each of the multiple PFLs, or the PRSs included in the PRS set configured in each PFL have many common features, such as the same subcarrier spacing, cyclic suffix length, etc.

[0138] In the PRS-based positioning measurement, the measurement can be performed independently based on each PRS set. For example, a measurement is performed based on PRS set 1 of TRP1 and a measurement result is obtained, and a measurement is performed based on PRS set 3 and a measurement result is obtained.

[0139] In an embodiment of the present disclosure, in order to improve positioning measurement accuracy, bandwidth aggregation (bandwidth aggregation) can be performed based on PRSs under continuous carriers of a single frequency band (intra-band). For example, referring to FIG1b , PRS sets of the same TRP in different PFLs can be aggregated. For example, in FIG1b , PRS set1 and PRS set3 of TRP1 in PFL1 and PFL2 can be aggregated together for measurement. Bandwidth aggregation of the PRS set of the same TRP in different PFLs can be understood as treating the PRSs distributed in two different frequency domains as one PRS. When performing positioning measurement at the receiving end, the PRS / PRS set on the two PFLs is regarded as an orthogonal frequency division multiplexing (OFDM) symbol for processing.

[0140] FIG1c shows a schematic diagram of muted and unmuted signals based on a muting mechanism in an exemplary embodiment of the present disclosure.

[0141] Referring to FIG1c , the network device 102 configures a reference signal for the terminal (wherein the terminal 101 and the network device 102 are not drawn, but the actual execution subject of the corresponding action is the terminal 101 or the network device 102). For example, two muting modes can be provided for the PRS set. In one muting mode, one or more PRSs involved in the PRS set are muted. For example, the shaded portion in the PRS set 1 selected by the oval frame in FIG1c is the muted PRS. In one muting mode, the entire PRS set is muted. For example, the shaded portion in the PRS set 1 selected by the square frame in FIG1c is the muted PRS.

[0142] In some embodiments, a muted or discarded reference signal may be understood as a reference signal that is not sent by the network device 102. The terminal 101 will not receive the muted or discarded reference signal in the corresponding time-frequency resources.

[0143] In the embodiment of the present disclosure, the terminal determines a PRS / PRS set for bandwidth aggregation, so as to perform positioning measurement based on the PRS / PRS set for bandwidth aggregation.

[0144] For the convenience of description in the embodiments of the present disclosure, the PRS / PRS set for bandwidth aggregation determined by the terminal is referred to as a first reference signal.

[0145] It is understood that the first reference signal is a reference signal used for positioning measurement. The first reference signal includes at least one of at least two PRSs and at least two PRS sets. For example, the first reference signal includes at least two PRSs, or includes at least two PRS sets. Alternatively, the first reference signal may include one or more PRSs and one or more PRS sets.

[0146] It is understood that in the embodiments of the present disclosure, PRS is sometimes also referred to as PRS resource, and PRS set is sometimes also referred to as PRS or PRS set. In the embodiments of the present disclosure, the terms are sometimes used interchangeably, and the consistency of their meanings should be understood.

[0147] In the embodiment of the present disclosure, the terminal determines the PRS / PRS set for bandwidth aggregation, which can be understood as a way for the terminal to select the PRS / PRS set for bandwidth aggregation to improve the accuracy of positioning measurement while considering increasing PRS transmission opportunities and reducing measurement delay.

[0148] FIG2a is a schematic diagram illustrating an interaction of a positioning measurement method according to an embodiment of the present disclosure. As shown in FIG2a , an embodiment of the present disclosure relates to a positioning measurement method for a communication system 100, the method comprising:

[0149] Step S2101 , the network device 102 sends first information to the terminal 101 .

[0150] In some embodiments, the terminal 101 receives first information sent by the network device 102 .

[0151] In some embodiments, the first information is used to indicate parameter information for the terminal to perform positioning measurement.

[0152] In some embodiments, the first information is used to indicate at least two PRSs or two PRS sets for which bandwidth aggregation is desired to be performed in positioning measurement.

[0153] In some embodiments, the first information is used to indicate a reference signal for performing positioning measurement.

[0154] In some embodiments, the first information may be configuration information, for example, configuration information sent by a network device to a terminal. The configuration information may be information for configuring positioning measurements.

[0155] In some embodiments, the first information is used to indicate a reference signal for which bandwidth aggregation is desired in positioning measurement.

[0156] In some embodiments, the reference signal for which bandwidth aggregation is desired in positioning measurement is called a second reference signal. The second reference signal includes at least two PRSs or two PRS sets configured by the network device for which bandwidth aggregation is desired in positioning measurement.

[0157] In some embodiments, the second reference signal includes a different reference signal.

[0158] In some embodiments, the second reference signal includes a PRS or a set of PRSs that can be used for bandwidth aggregation and a PRS or a set of PRSs that cannot be used for bandwidth aggregation.

[0159] In some embodiments, the PRS or PRS set that cannot be used for bandwidth aggregation generally includes at least one of the following: a discarded PRS or PRS set, and a muted PRS or PRS set.

[0160] In some embodiments, the generation of discarded PRSs or PRS sets is based on the following reasons: PRSs are transmitted in the PPW, and the terminal performs measurements in the PPW. Priorities of various channels or signals are defined in the PPW. If a high-priority channel or signal needs to be transmitted, the PRSs in the PPW are discarded.

[0161] In some embodiments, the muted PRS or PRS set is generated based on a muting pattern.

[0162] In some embodiments, the PRS or PRS set that can be used for wideband aggregation typically includes non-dropped signals and non-muted signals.

[0163] In some embodiments, the first information is used to indicate one or more lists, wherein the one or more lists include the PRS or PRS set for which bandwidth aggregation is desired.

[0164] In some embodiments, the first information is used to indicate one or more PRS lists, and the one or more PRS lists include the second reference signal.

[0165] In some embodiments, the first information is used to indicate one or more PRS lists, where the one or more PRS lists include one or more PRS lists including the PRS or PRS set that is desired to be bandwidth aggregated.

[0166] In some embodiments, the first information is used to indicate one or more identifiers, and the PRS or PRS set included in the second reference signal has the same identifier.

[0167] In some embodiments, the first information is used to indicate one or more identifiers, and the PRS or PRS set to be bandwidth aggregated is expected to have the same identifier.

[0168] In some embodiments, a muted or discarded reference signal may be understood as a reference signal that is not sent by the network device 102. The terminal 101 will not receive the muted or discarded reference signal in the corresponding time-frequency resources.

[0169] In some embodiments, the muted or discarded PRS or PRS set in the second reference signal is referred to as a first sub-reference signal, and the non-muted or non-discarded PRS or PRS set in the second reference signal is referred to as a second sub-reference signal.

[0170] In this embodiment of the present disclosure, when the second reference signal configured in the first information sent by network device 102 includes a first sub-reference signal, although network device 102 expects to perform bandwidth aggregation based on the first sub-reference signal, because network device 102 did not send the first sub-reference signal, terminal 101 cannot perform bandwidth aggregation based on the first sub-reference signal. Continuing with Figure 1c, network device 102 indicates that it expects to perform bandwidth aggregation on PRS set 1 and PRS set 2. However, the terminal cannot perform bandwidth aggregation on PRS set 1 and PRS set 2.

[0171] In some embodiments, the second reference signal includes a muted or dropped PRS or a set of PRSs, and the second reference signal includes a non-muted or non-dropped PRS or a set of PRSs.

[0172] In some embodiments, the second reference signal includes a first sub-reference signal.

[0173] In some embodiments, the second reference signal includes a second sub-reference signal.

[0174] In some embodiments, the second reference signal includes a first sub-reference signal and a second sub-reference signal.

[0175] In some embodiments, the PRS or PRS set desired to be bandwidth aggregated includes at least one of the following: a muted PRS or PRS set, a discarded PRS or PRS set, an unmuted PRS or PRS set, and an undiscarded PRS or PRS set.

[0176] In some embodiments, network device 102 sends configuration information, where the configuration information includes first information. Optionally, terminal 101 receives the configuration information. The configuration information is used to configure a PRS or a set of PRSs that the network device desires to perform bandwidth aggregation on during positioning measurement. The configuration information may be Radio Resource Control (RRC) signaling or Media Access Control–Control Element (MAC-CE) signaling.

[0177] In step S2102 , the terminal 101 determines a PRS or a PRS set for bandwidth aggregation.

[0178] In some embodiments, the bandwidth-aggregated PRS or PRS set is a bandwidth-aggregated PRS or PRS set selected by a terminal in positioning measurement.

[0179] In some embodiments, the PRS or PRS set for bandwidth aggregation includes at least two PRSs or at least two PRS sets for positioning measurement, wherein the at least two PRSs or PRS sets are used for bandwidth aggregation.

[0180] In some embodiments, the PRS or PRS set to be bandwidth aggregated is determined based on the first information.

[0181] In some embodiments, the PRS or PRS set to be bandwidth aggregated is the same as the PRS or PRS set to be bandwidth aggregated indicated by the first information.

[0182] In some embodiments, the PRS or PRS set to be bandwidth aggregated includes a PRS or PRS set that is desired to be bandwidth aggregated.

[0183] In some embodiments, the PRS or PRS set for bandwidth aggregation is a partial PRS or PRS set in the PRS or PRS set configured by the first information.

[0184] In some embodiments, the PRS or PRS set to be bandwidth aggregated includes at least one of the PRS or PRS set that is not muted and the PRS or PRS set that is not dropped among the PRS or PRS set to be bandwidth aggregated.

[0185] In some embodiments, the terminal 101 determines the PRS or PRS set to be bandwidth aggregated in the positioning measurement based on the PRS or PRS set to be bandwidth aggregated.

[0186] In some embodiments, the terminal 101 determines the PRS or PRS set for which bandwidth aggregation is desired as the PRS or PRS set for which bandwidth aggregation is performed in the positioning measurement.

[0187] In some embodiments, the terminal 101 determines the non-muted PRS or PRS set in the PRS or PRS set for which bandwidth aggregation is desired, and at least one PRS or PRS set in the PRS or PRS set for which bandwidth aggregation is desired, as the PRS or PRS set for which bandwidth aggregation is performed in the positioning measurement.

[0188] In some embodiments, the terminal 101 determines at least one of: a muted PRS or a set of PRSs, a dropped PRS or a set of PRSs, an unmuted PRS or a set of PRSs, and a non-dropped PRS or a set of PRSs.

[0189] Step S2103 , the network device 102 sends third information to the terminal 101 .

[0190] In some embodiments, the third information is used to indicate whether the terminal is allowed to independently select a PRS or a PRS set for bandwidth aggregation in positioning measurement.

[0191] In some embodiments, the third information is used to indicate that the terminal is allowed to independently select a PRS or a PRS set for bandwidth aggregation in positioning measurement, that is, the third information is used to indicate that the terminal can independently select a PRS for bandwidth aggregation.

[0192] In some embodiments, the third information is used to indicate that the terminal is allowed to independently select the PRS or PRS set for bandwidth aggregation in the positioning measurement. When the PRS or PRS set in the reference signal for bandwidth aggregation is expected to be muted or discarded, the terminal can perform positioning measurement based on the PRS or PRS set that is not muted or discarded.

[0193] In some embodiments, the third information is used to indicate that the terminal is not allowed to independently select a PRS or a PRS set for bandwidth aggregation in positioning measurement, that is, the third information is used to indicate that the terminal cannot independently select a PRS for bandwidth aggregation.

[0194] In some embodiments, the third information is used to indicate that the terminal is not allowed to independently select a PRS or a PRS set for bandwidth aggregation in positioning measurement, and the terminal is not allowed to perform positioning measurement based on a PRS or a PRS set that is not discarded or muted. For example, when a reference signal for which bandwidth aggregation is desired includes a muted or discarded PRS or a PRS set, the terminal is not allowed to perform positioning measurement based on a PRS or a PRS set that is not discarded or muted.

[0195] In some embodiments, when the third indication information indicates that the terminal is allowed to independently select a PRS or a PRS set for bandwidth aggregation in positioning measurement, the terminal 101 determines a PRS or a PRS set that is not muted or discarded.

[0196] In some embodiments, the third information is configuration information, for example, based on resource pool pre-configuration.

[0197] In some embodiments, the third information is indication information, such as information based on network indication.

[0198] In step S2104, the terminal 101 performs positioning measurement based on the PRS or PRS set for bandwidth aggregation.

[0199] In some embodiments, the terminal 101 performs positioning measurement at a time corresponding to the determined PRS or PRS set for bandwidth aggregation in the positioning measurement.

[0200] For example, a schematic diagram of a positioning measurement signal according to an exemplary embodiment is shown in FIG2b . At time t2, the non-muted and non-discarded RPS sets of the three PFLs, PFL1, PFL2, and PFL3, are aggregated. For example, the RPS sets corresponding to the non-shaded portions of PRS set 2 of PFL2, PRS set 3 of PFL3, and PRS set 1 of PFL1 are aggregated, and positioning measurement is performed.

[0201] At time t3 and time t4, terminal 101 aggregates PRS set 2 and PRS set 3 of PFL 2 and PFL 3 for bandwidth aggregation, and performs positioning measurement.

[0202] In some embodiments, terminal 101 performs positioning measurements on PRSs or PRS sets that are not muted or dropped.

[0203] In some embodiments, the third indication information indicates that the terminal is allowed to independently select the PRS or PRS set for bandwidth aggregation in the positioning measurement, and the terminal 101 measures the PRS or PRS set that is not muted or discarded.

[0204] In some embodiments, positioning measurements are performed at the time corresponding to the determined PRS or PRS set for bandwidth aggregation in the positioning measurement. For example, a schematic diagram of a positioning measurement signal according to an exemplary embodiment is shown in FIG2b . Since it is determined that the terminal will only perform measurements at the time corresponding to a PRS or PRS set that is not muted or discarded, the terminal will only perform measurements at time t2 and will not perform measurements at times t3 or t4.

[0205] In some embodiments, terminal 101 does not perform positioning measurements based on PRSs or PRS sets that are not muted or dropped.

[0206] In some embodiments, terminal 101 does not perform positioning measurements on PRSs or PRS sets that are not muted or discarded.

[0207] In some embodiments, the terminal 101 does not perform positioning measurements at a time corresponding to at least one of the non-muted PRS or PRS sets in the PRS or PRS sets for which bandwidth aggregation is desired, and the non-discarded PRS or PRS sets.

[0208] In some embodiments, when the third indication information indicates that the terminal is not allowed to independently select a PRS or a PRS set for bandwidth aggregation in positioning measurement, the terminal 101 does not perform positioning measurement.

[0209] In some embodiments, when the third indication information indicates that the terminal is not allowed to independently select a PRS or PRS set for bandwidth aggregation during positioning measurement, terminal 101 does not perform positioning measurement at the time corresponding to at least one of a non-muted PRS or PRS set and a non-discarded PRS or PRS set among the PRS or PRS sets for which bandwidth aggregation is desired. For example, a schematic diagram of a positioning measurement signal according to an exemplary embodiment is shown. As shown in FIG2b , because the third indication information indicates that the terminal is not allowed to independently select a PRS or PRS set for bandwidth aggregation during positioning measurement, the terminal does not perform positioning measurement at times t3 and t4.

[0210] Step S2105 , the terminal 101 reports the second information to the network device 102 .

[0211] In some embodiments, the second information is used to indicate a measurement result of the positioning measurement. For example, the second information is used to indicate that the positioning measurement result is to be reported to the network, and at the same time, which PRSs or PRS sets are aggregated to obtain the measurement result.

[0212] In some embodiments, the second information is used to indicate positioning frequency layer information.

[0213] In some embodiments, the second information is used to indicate a component carrier.

[0214] For example, the second information indicates that the reported content includes a component carrier or a positioning frequency layer list.

[0215] In some embodiments, the positioning frequency layer information is used to indicate the PRSs or PRS sets under which component carriers are bandwidth aggregated during positioning measurements. For example, the positioning frequency layer information may indicate that the measurement result is the result of aggregating the PRSs or PRS sets under the component carriers or positioning frequency layer lists in the list.

[0216] In some embodiments, the second information is used to indicate whether to perform positioning measurement based on a PRS or a PRS set for bandwidth aggregation.

[0217] In some embodiments, the second information is used to indicate whether the measurement result of the positioning measurement was obtained based on the PRS or PRS set for which bandwidth aggregation is desired. For example, the second information is used to inform the network device whether the measurement result was obtained based on the PRS or PRS set for which aggregation is required based on the network configuration.

[0218] In some embodiments, the positioning frequency layer information is used to indicate the PRS or PRS set for bandwidth aggregation in the positioning measurement. For example, the positioning frequency layer information indicates that the measurement result is the result of aggregating the PRS or PRS set under these component carriers or positioning frequency layer lists.

[0219] In some embodiments, the second information is used to indicate whether to perform positioning measurement based on a PRS or a PRS set in which bandwidth aggregation is performed on the second reference signal.

[0220] In some embodiments, the second information is used to indicate whether the positioning measurement is performed based on a PRS or PRS set for which bandwidth aggregation is desired. For example, the second information is used to inform the network device whether the measurement result is obtained based on a PRS or PRS set for which aggregation is desired according to the network configuration.

[0281] In some embodiments, the above method may include the method described in the above embodiments related to the communication system 100, the terminal 101, the network device 102, etc., which will not be repeated here.

[0282] The method provided in the embodiment of the present disclosure includes the following:

[0283] Method 1: Users select the PRS resource or resource set to be aggregated

[0284] Configuration: The network configures for the user which two or more PRS resources or resource sets need to be aggregated for bandwidth in positioning measurement, specifically

[0285] Configure a PRS set / resource for bandwidth aggregation list for each TRP. The PRS resource sets or resources in the list are the reference signals that the network wants to aggregate.

[0286] Alternatively, configure multiple link IDs. In the PRS set / resource configuration, the reference signals with the same link ID are included as the reference signals that need to be aggregated.

[0287] Measurement: When performing positioning measurements, the user determines whether the PRS being measured will be transmitted based on the muting option or the priority of each channel or channel in the PPW, and then selects the PRS set to be aggregated. If there are PRSs that will not be transmitted, the user performs positioning measurements based on other PRS set(s).

[0288] As shown in the figure below, at t1 and t2, the PRS sets of the three PFLs are aggregated; at t3 and t4, the user only aggregates the PRSs of PFL2 and PFL3.

[0289] Method 2: The network indicates whether the user can select the PRS resource or resource set to be aggregated

[0290] If the network indicates that the user can make his own choice, the user will make the choice in the same way as in Method 1 and report it.

[0291] If the network indicates that the user cannot make a selection, the user will only perform measurements when no PRS resources / resource sets are muted or discarded. As shown in the figure below, the user will not perform measurements at t3 and t4, but will perform measurements at t2.

[0292] In some embodiments, a method for a user to determine a PRS resource / resource set for bandwidth aggregation includes determining whether the PRS to be measured will be sent according to the muting option or the priority of each channel or channel in the PPW when performing positioning measurement based on the PRS, and then selecting the PRS resource / resource set to be aggregated.

[0293] If there are PRS resources that are not sent, the user will only measure other PRSs in the PRS resource set that the network expects to aggregate when performing positioning measurements. If the PRS resource set that the network expects to aggregate is not sent, no measurement will be performed.

[0294] In some embodiments, network configuration information is received, and the configuration information is used to configure for a user which two or more PRS resources or resource sets are expected to be bandwidth aggregated in positioning measurements. A PRS set / resource for bandwidth aggregation list is configured for each TRP, and the PRS resource sets or resources in the list are reference signals that the network wishes to aggregate. Alternatively, multiple link IDs are configured, and the PRS set / resource configuration includes the reference signals that need to be aggregated.

[0295] In some embodiments, after the user performs measurement based on the selected PRS resource / resource set, the positioning measurement result is reported to the network, and at the same time, the measurement result obtained by the aggregation of the PRS resource / resource set is reported.

[0296] In some embodiments, the report includes a CC or PFL list, indicating that the measurement result is the result of aggregating the PRS resources / resource sets under these CC / PFLs.

[0297] In some embodiments, a 1-bit representation is added to the report content to inform the network whether the measurement result is obtained by measuring the PRS resource / resource set aggregated based on the needs of the network configuration.

[0298] In some embodiments, the network receives an indication message indicating that the user can select the PRS resource or resource set to be aggregated.

[0299] In some embodiments, the network receives an indication that the user cannot select the PRS resource or resource set to be aggregated.

[0300] The user will only perform measurements when no PRS resources / resource sets are muted or discarded. As shown in the figure below, the user will not perform measurements at t3 and t4, but will perform measurements at t2.
