Description

Technical Field

[0001] The present disclosure relates to the field of communication systems, and more particularly, to a wireless communication method and apparatus for positioning measurement. Background Art

[0002] The positioning performance and accuracy of current positioning measurements are limited by the bandwidth of the positioning reference signal (PRS). In current systems, PRS can be transmitted on multiple frequency layers, but new radio (NR) systems can only support positioning measurements based on PRS separately in each frequency layer. The PRS bandwidth of a positioning frequency layer is limited to 100MHz. Therefore, positioning performance is also limited. Current NR systems cannot aggregate PRSs from multiple frequency layers to form an equivalent larger PRS bandwidth, thereby potentially improving the accuracy of positioning measurements.

[0032] Positioning technology is one of the core technologies of wireless communication systems and navigation systems. 5G NR systems support positioning technology. In the 3rd Generation Partnership Project (3GPP) Release 16, the following positioning schemes are specified: downlink (DL) time difference of arrival (TDOA) method, uplink (UL) TDOA method, multiple round trip time (RTT) method, downlink angle of departure (DL-AoD) method, uplink angle of arrival (AoA) method, and enhanced cell identifier (E-CID) method.

[0033] In 3GPP NR, the downlink positioning reference signal (PRS) is introduced to support downlink positioning measurements, and the sounding reference signal (SRS) for positioning is introduced to support uplink positioning measurements. Specifically, NR Release 16 supports the following positioning measurements: DL reference signal time difference (RSTD) measured by DL PRS, UL relative time of arrival (RTOA) measured by SRS for positioning, UE receive-transmit (Rx-Tx) time difference, gNB Rx-Tx time difference, DL PRS reference signal received power (RSRP), UL SRS RSRP, and UL AoA.

[0034] NR-based positioning solutions involve the following functional entities: UE: The UE measures DL PRS resources sent from multiple different transmission / reception points (TRPs) or SRS resources sent for positioning. TRP: To determine the location of a UE, multiple TRPs are usually involved. Each TRP can send DL PRS to the UE or receive and measure SRS sent by the UE for positioning. Location server: This can also be called location management function (LMF).

[0035] Figure 1An example of NR positioning based on DL measurement is shown. As shown in the example, the basic process is as follows. The LMF and TRP coordinate the DL PRS configuration. Each TRP sends DL PRS resources according to the configuration. The UE measures the DL PRS resources sent from multiple TRPs, and then measures the DL PRS RSRP and / or DL ​​RSTD. The UE reports the positioning measurement results to the LMF. Finally, the LMF calculates the position of the UE based on the reported positioning measurement results. Specifically, in the DL-AoD method, the UE measures the RSRP or path RSRP of one or more DL RS resources, and then reports the measurement results to the LMF. The LMF can determine the departure angle of a UE relative to each TRP, and then the LMF can calculate the position of the UE.

[0036] As specified in NR, a UE may be configured with one or more DL PRS resource sets, each of which may consist of one or more DL PRS resources. For each DL PRS resource set, the UE is provided with the following configuration parameters:

[0037] dl-PRS-Periodicity-and-ResourceSetSlotOffset defines the DL PRS resource period and takes a value time slots, where μ = 0, 1, 2, 3 for dl-PRS-SubcarrierSpacing = 15, 30, 60, 120 kHz, respectively, and defines the time slot offset of the DL PRS resource set relative to SFN0 time slot 0. All DL PRS resources in a DL PRS resource set are configured with the same DL PRS resource period.

[0038] dl-PRS-MutingOption1 and dl-PRS-MutingOption2 define the time locations in a DL PRS resource set where DL PRS resources are not expected to be transmitted. If dl-PRS-MutingOption1 is configured, each bit in the bitmap of dl-PRS-MutingOption1 corresponds to a configurable number of consecutive instances of a DL PRS resource set, provided by the higher-layer parameter dl-prs-MutingBitRepetitionFactor, where for an instance indicating muting, all DL PRS resources in that resource set are muted. The length of the bitmap can be {2, 4, 6, 8, 16, 32} bits. If dl-PRS-MutingOption2 is configured, each bit in the bitmap of dl-PRS-MutingOption2 corresponds to a single repetition index for each DL PRS resource in each instance of nr-DL-PRS-ResourceSet, and the length of the bitmap is equal to the value of dl-PRS-ResourceRepetitionFactor.

[0039] NR-DL-PRS-SFN0-Offset defines the time offset of SFN0 timeslot 0 of the transmitting cell relative to SFN0 timeslot 0 of the reference cell.

[0040] The bandwidth of the DL PRS resource may be outside the bandwidth of an active bandwidth part (BWP), and the subcarrier spacing used by the DL PRS resource may also be different from the subcarrier spacing of the active BWP. Therefore, the UE requires measurement gaps to measure the DL PRS resource. The measurement gaps used for positioning are configured via radio resource control (RRC). When the UE needs to measure the DL PRS resource and there is no measurement gap, the UE can request a measurement gap via RRC signaling.

[0041] The positioning performance and accuracy of current positioning measurements are limited by the bandwidth of the Positioning Reference Signal (PRS). In current systems, PRS can be transmitted across multiple frequency layers, but New Radio (NR) systems only support positioning measurements based on PRS alone in each frequency layer. The PRS bandwidth of a single positioning frequency layer is limited to 100 MHz, thus limiting positioning performance. Current NR systems cannot aggregate PRS signals from multiple frequency layers to create an equivalently larger PRS bandwidth, potentially improving positioning measurement accuracy.

[0042] Some embodiments of the present disclosure provide a solution for phase difference measurement for positioning. Figure 2In some embodiments, one or more user equipment (UE) devices 10 and a base station (e.g., a next-generation Node B (gNB) or eNB) 20 communicating in a communication network system 30 (e.g., an NR system) according to an embodiment of the present disclosure are provided.

The UE may then aggregate them together to obtain the corresponding positioning measurement. The UE may report the positioning measurement results to the system. For each positioning measurement, the UE may report whether the measurement result is obtained by aggregating DL PRS resources. For each measurement result, the UE may also report the IDs of the DL PRS resources that the UE aggregated to obtain the measurement results.

[0067] In an exemplary method, the system may configure one or more DL PRS resource set configurations for the UE through higher layer signaling. Each DL PRS resource set consists of one or more DL PRS resources. When configuring the DL PRS resources, the system may provide indication information indicating which DL PRS resources the UE may aggregate for positioning measurement. For example, the system may provide indication information of a first DL PRS resource and a second DL PRS resource, the indication information indicating to the UE that the UE may aggregate the first DL PRS resource and the second DL PRS resource to obtain positioning measurement, such as RSTD measurement, UE Rx-Tx time difference measurement, and / or PRS RSRP measurement.

[0068] In a first example, the system may provide a first indicator in the configuration of a DL PRS resource. The indicator may be set to a number of values, such as 0, 1, 2, 3, etc. The first indicator in a DL PRS resource is used to indicate whether the DL PRS resource can be aggregated with another DL PRS resource. DL PRS resources with the same first indicator set to the same value may be aggregated for positioning measurements. In other words, the UE may aggregate two DL PRS resources with the same first indicator set to obtain positioning measurements.

[0069] In a second example, the system may provide one or more lists of DL PRS resource IDs to indicate whether two DL PRS resources may be aggregated for positioning measurement. DL PRS resources configured with DL PRS resource IDs in the same list may be aggregated for positioning measurement. For example, the system may provide a list of DL PRS resource IDs aggregated for positioning measurement: {first DL PRS resource ID, second DL PRS resource ID}. The UE may then aggregate the DL PRS resource with the first DL PRS resource ID and the DL PRS resource with the second DL PRS resource ID for positioning measurement.

[0070] In a third example, for the configuration of DL PRS resources, the UE may be configured with one or more DL PRS positioning frequency layer configurations, where a DL PRS positioning frequency layer is defined as a set of DL PRS resource sets with common parameters. A DL PRS positioning frequency layer configuration includes the following parameters common to all DL PRS resource sets in the positioning frequency layer: PRS subcarrier spacing, cyclic prefix, and / or PRS point A. In a DL PRS positioning frequency layer configuration, the UE may be provided with one or more DL PRS resource sets, each of which may include one or more DL PRS resources.

[0071] To support DL PRS resource aggregation indication, in some examples, the system may provide an indicator in a DL PRS positioning frequency layer configuration, the value of which may indicate whether DL PRS resources in two DL PRS positioning frequency layer configurations can be aggregated for positioning measurement. For example, the system provides an indicator in the first DL PRS positioning frequency layer and an indicator in the second DL PRS positioning frequency layer. If the indicators in the two DL PRS positioning frequency layer configurations are set to the same value, the UE may aggregate one DL PRS resource in the first DL PRS positioning frequency layer and the corresponding DL PRS resource in the second DL PRS positioning frequency layer for positioning measurement.

[0072] In some examples, the system may provide an indicator in a DL PRS resource set, the value of which may indicate whether the DL PRS resources in the two DL PRS resource sets can be aggregated for positioning measurement. For example, the system provides an indicator in the first DL PRS resource set and an indicator in the second DL PRS resource set. If the indicators in the two DL PRS resource sets are set to the same value, the UE may aggregate one DL PRS resource in the first DL PRS resource set and the corresponding DL PRS resource in the second DL PRS resource set for positioning measurement.

[0073] In a fourth example, for the configuration of DL PRS resources, the UE may be configured with one or more DL PRS positioning frequency layer configurations, wherein the DL PRS positioning frequency layer is defined as a collection of DL PRS resource sets with common parameters. A DL PRS positioning frequency layer configuration includes the following parameters common to all DL PRS resource sets in the positioning frequency layer: PRS subcarrier spacing, cyclic prefix, and / or PRS point A. In a DL PRS positioning frequency layer configuration, the UE may be provided with one or more DL PRS resource sets, each DL PRS resource set may include one or more DL PRS resources. In order to support DL PRS resource aggregation indication, the system may provide an associated DL PRS positioning frequency layer configuration in the first DL PRS positioning frequency layer configuration. With this configuration, all DL PRS resource sets configured in the first DL PRS positioning frequency layer configuration will also be applicable to the associated DL PRS positioning frequency layer. The UE may aggregate the resources of a DL PRS in the first DL PRS positioning frequency layer and the corresponding DL PRS resources in the associated DL PRS positioning frequency layer for positioning measurement.

[0074] For example, the following message could be used to support this new functionality:

[0075] IE associated_nr-DL-PRS-PositioningFrequencyLayer can configure an associated DL PRS positioning frequency layer for DL ​​PRS resource aggregation. In some cases, the system may request the UE to aggregate DL PRS resources in more than two positioning frequency layers for positioning measurement. Therefore, the system can provide multiple associated DL PRS positioning frequency layer configurations in the first DL PRS positioning frequency layer configuration. In the above message design example, IE 2ndAssociated_nr-DL-PRS-PositioningFrequencyLayer can configure the second associated DL PRS positioning frequency layer for DL ​​PRS resource aggregation. In another example, IE associated_nr-DL-PRS-PositioningFrequencyLayer can provide a list of associated DL PRS positioning frequency layers.

[0076] In a fifth example, the UE may determine whether two DL PRS resources on two different PRS positioning frequency layers can be aggregated for positioning measurement based on the configuration of the DL PRS resources. For example, the first DL PRS positioning frequency layer and the second DL PRS positioning frequency layer are configured with the same subcarrier spacing and cyclic prefix. If the first DL PRS resource in the first DL PRS positioning frequency layer and the second DL PRS resource in the second DL PRS positioning frequency layer are transmitted in the same time slot and the same OFDM symbol, the UE may aggregate the first DL PRS resource and the second DL PRS resource for positioning measurement.

[0077] In an exemplary method, the system may request a UE to obtain a positioning measurement result and report the positioning measurement result to the system. For example, the system may request the UE to report the positioning measurement result of DL-TDOA positioning. For example, the system may request the UE to report the positioning measurement result of DL-AoD positioning. For example, the system may request the UE to report the UE Rx-Tx time difference measurement result. For one positioning measurement, the system may request the UE to obtain the positioning measurement result by aggregating multiple DL PRS resources on different DL PRS positioning frequency layers. In each positioning measurement report, the UE may report that a positioning measurement result is obtained by aggregating DL PRS resources in different DL PRS positioning frequency layers. For each positioning measurement report obtained by aggregating multiple DL PRS resources, the UE may also report the ID of the DL PRS resource that was aggregated to obtain the corresponding positioning measurement result.

[0078] In the first example, for DL-TDOA positioning, the system may request the UE to report DL RSTD measurements to the system. Depending on the configuration of DL PRS resources, the UE may obtain DL RSTD measurements by aggregating DL PRS resources. The UE may then report one or more DL RSTD measurements to the system. For each reported DL RSTD measurement, the UE may report the following:

[0079] An indicator indicating whether the corresponding DL RSTD measurement is obtained by aggregating DL PRS resources.

[0080] The UE performs aggregation to obtain the DL PRS resource ID of the corresponding DL RSTD measurement result.

[0081] RSRP measurement of the corresponding aggregated DL PRS resources used to obtain DL RSTD measurement.

[0082] The UE may also report the path RSRP of the aggregated DL PRS resources.

[0083] The UE may also report the relative arrival time of the aggregated DL PRS resources.

[0084] In a second example, for multi-RTT positioning, the system may request the UE to report UE Rx-Tx time difference measurements to the system. Depending on the configuration of DL PRS resources, the UE may obtain UE Rx-Tx time difference measurements by aggregating DL PRS resources. The UE may then report one or more UE Rx-Tx time difference measurements to the system. For each reported UE Rx-Tx time difference measurement, the UE may report the following:

[0085] Indicator used to indicate whether the corresponding UE Rx-Tx time difference measurement is obtained by aggregating DL PRS resources.

[0086] The UE performs aggregation to obtain the ID of the DL PRS resource corresponding to the UE Rx-Tx time difference measurement result.

[0087] RSRP measurement of the corresponding aggregated DL PRS resources used to obtain UE Rx-Tx time difference measurement.

[0088] The UE may also report the path RSRP of the aggregated DL PRS resources.

[0089] The UE may also report the relative arrival time of the aggregated DL PRS resources.

[0090] In the third example of DL-AoD positioning, the system may request the UE to report PRS RSRP measurements to the system. Depending on the configuration of DL PRS resources, the UE may obtain PRS RSRP measurements by aggregating DL PRS resources. The UE may then report one or more PRS RSRP measurements to the system. For each reported UE PRS RSRP measurement, the UE may report the following:

[0091] Indicator used to indicate whether the corresponding PRS RSRP measurement is obtained by aggregating DL PRS resources.

[0092] The UE performs aggregation to obtain the ID of the DL PRS resource corresponding to the PRS RSRP measurement result.

[0093] The UE may also report the path RSRP of the aggregated DL PRS resources.

[0094] The proposed method enables NR systems to aggregate multiple DL PRS resources on different frequency layers to form an equivalent PRS with a larger bandwidth for positioning measurements. A larger PRS bandwidth can improve the accuracy of positioning measurements, thereby enhancing the performance of positioning services.
