[0022] Detailed Description Various exemplary arrangements of the present solution are described below with reference to the accompanying figures to enable those skilled in the art to make and use the present solution. As will be apparent to those skilled in the art after reading this disclosure, various changes or modifications of the embodiments described herein can be made without departing from the scope of the present solution. Thus, the present solution is not limited to the exemplary arrangements and applications described and illustrated herein. Additionally, any specific order or hierarchy of steps in the methods disclosed herein is merely an example approach. Based on design preferences, the specific order or hierarchy of steps in a disclosed method or process can be rearranged while remaining within the scope of the present solution. Thus, those skilled in the art will understand that the methods and techniques disclosed herein present various steps or acts in a sample order, and that the present solution is not limited to the specific order or hierarchy presented, unless expressly stated otherwise.

[0023] To improve positioning accuracy, carrier phase positioning (CPP) technology is utilized as an auxiliary tool to improve the shortcomings of current positioning technology. For example, the present technical solution targets technical improvements to TDOA (Time Difference of Arrival), AOA (Angle of Arrival), AOD (Angle of Departure), multiple RTT (Multiple Round Trip Time), and other positioning methods to achieve precise positioning function by collecting at least phase information of different positioning reference signals (PRS) or sounding reference signals (SRS). The measured / reported phase information is used to improve positioning performance and identify possible error sources.

[0024] FIG. 1 illustrates an example wireless communication system 100 in which the techniques disclosed herein may be implemented, according to certain implementations of the present disclosure. In the following discussion, the wireless communication system 100 may implement any wireless network, such as a cellular network or a narrowband Internet of Things (NE-IoT) network, and is referred to herein as “system 100.” Such example system 100 includes a BS 102, a UE 104, and a cluster of cells 126, 130, 132, 134, 136, 138, and 140 that overlay a geographic area 101, which may communicate with each other via communication link 110 (e.g., a wireless communication channel). In FIG. 1, the BS 102 and the UE 104 are contained within the respective geographic boundaries of cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one BS that operates within its allocated bandwidth and provides adequate wireless coverage to its intended users.

[0025] For example, the BS 102 may operate within an allocated channel transmission bandwidth to provide adequate coverage to the UE 104. The BS 102 and the UE 104 may communicate via downlink radio frames 118 and uplink radio frames 124, respectively. Each radio frame 118 / 124 may be further divided into subframes 120 / 127, which may include data symbols 122 / 128. In this disclosure, the BS 102 and the UE 104 are generally described herein as non-limiting examples of "communication nodes" that may practice the methods disclosed herein. Such communication nodes may be capable of wireless and / or wired communication according to various implementations of the present solution.

[0026] In some implementations, the wireless communication system 100 may support multiple-input multiple-output (MIMO) communication. For example, MIMO is a key technology in new radio (NR) systems. MIMO may be functional in both frequency division duplex (FDD) and time division duplex (TDD) systems, among others. MIMO technology may support communication using reporting mechanisms such as channel status information (CSI). The CSI report may include various types, portions, groups, and fields. The techniques described herein may provide improvements to various aspects of CSI reporting and the reporting process. For example, a wireless communication device may receive multiple reference signals and configuration parameters from a network by the wireless communication device. The wireless communication device may determine a CSI report based on the multiple reference signals and configuration parameters, where the CSI report includes CSI part 1 and CSI part 2. The wireless communication device may report the CSI report to the network. In some cases, the reporting process may include one or more of the following: configuration parameters may be configured to enable two or more channel quality indicators (CQIs) within a CSI report; the reference signal may be aperiodic or semi-persistent; and each of the CSI window length, FDD or TDD basic unit size, offset between two CSI reference signal (CSI-RS) resources, and length of the FDD or TDD basis vector is greater than or equal to a threshold. Additionally or alternatively, the wireless communication device may transmit a user equipment (UE) capability report to the network indicating that the wireless communication device supports a certain number of CQI reports, where the number is a positive integer. The wireless communication system may implement a codebook to further support CSI reporting, among other uses.

[0027] 2 illustrates a block diagram of an exemplary wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) in accordance with some implementations of the present solution. System 200 may include components and elements configured to support known or conventional operational features not necessarily described in detail herein. In one illustrative implementation, system 200 may be used to communicate (e.g., transmit and receive) data symbols within a wireless communication environment, such as wireless communication environment 100 of FIG. 1, as described above.

[0028] System 200 generally includes a BS 202 and a UE 204. BS 202 includes a base station (BS) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each of which is coupled and interconnected, as needed, with one another via a data communication bus 220. UE 204 includes a UE transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each of which is coupled and interconnected, as needed, with one another via a data communication bus 240. BS 202 communicates with UE 204 via a communication channel 250, which may be any wireless channel or other medium suitable for the transmission of data as described herein.

[0029] System 200 may further include any number of modules other than those shown in FIG. 2 . Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in connection with the implementations disclosed herein may be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, the various illustrative components, blocks, modules, circuits, and steps are described generally in terms of their functionality. Whether such functionality is implemented as hardware, firmware, or software may depend on the particular application and design constraints imposed on the overall system. Those familiar with the concepts described herein may implement such functionality in a suitable manner for each particular application, but such implementation decisions should not be interpreted as limiting the scope of the present disclosure.

[0030] According to some implementations, the UE transceiver 230 may be referred to herein as an “uplink” transceiver 230, including a radio frequency (RF) transmitter and an RF receiver, each including circuitry coupled to the antenna 232. A duplex switch (not shown) may alternatively couple the uplink transmitter or receiver to the uplink antenna in a time-duplexed manner. Similarly, according to some implementations, the BS transceiver 210 may be referred to herein as a “downlink” transceiver 210, including an RF transmitter and an RF receiver, each including circuitry coupled to the antenna 212. A downlink duplex switch may alternatively couple the downlink transmitter or receiver to the downlink antenna 212 in a time-duplexed manner. The operation of the two transceiver modules 210 and 230 may be coordinated in time such that the downlink transmitter is coupled to the downlink antenna 212 at the same time that the uplink receiver circuitry is coupled to the uplink antenna 232 for reception of transmissions over the wireless transmission link 250. In some implementations, there is close time synchronization with a minimum guard time between duplex direction changes.

[0031] The UE transceiver 230 and the BS transceiver 210 are configured to communicate via a wireless data communication link 250 and cooperate with a suitably configured RF antenna arrangement 212 / 232 capable of supporting a particular wireless communication protocol and modulation scheme. In some illustrative implementations, the UE transceiver 230 and the BS transceiver 210 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G and 6G standards and the like. However, it should be understood that the present disclosure is not necessarily limited in application to any particular standard and associated protocol. Rather, the UE transceiver 230 and the BS transceiver 210 may be configured to support alternative or additional wireless data communication protocols, including future standards or variations thereof.

[0032] According to various implementations, the BS 202 may be, for example, an evolved NodeB (eNB), a serving eNB, a target eNB, a femto station, or a pico station. In some implementations, the UE 204 can be various types of user devices, such as a mobile phone, a smartphone, a personal digital assistant (PDA), a tablet, a laptop computer, a wearable computing device, etc. The processor modules 214 and 236 may be implemented or realized with a general-purpose processor, an associative memory, a digital signal processor, an application-specific integrated circuit, a field-programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described herein. As such, a processor may be realized as a microprocessor, a controller, a microcontroller, a state machine, or the like. A processor may also be implemented as a combination of computing devices, such as a digital signal processor and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a digital signal processor core, or any other such configuration.

[0033] Furthermore, the methods described in connection with the implementations disclosed herein may be implemented in hardware, firmware, software modules executed directly by processor modules 214 and 236, respectively, or in any practical combination thereof. Memory modules 216 and 234 may be embodied as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. In this regard, memory modules 216 and 234 may be coupled to processor modules 210 and 230, respectively, such that processor modules 210 and 230 may read information from and write information to memory modules 216 and 234, respectively. Memory modules 216 and 234 may also be integrated within their respective processor modules 210 and 230. In some implementations, memory modules 216 and 234 may each include cache memory for storing temporary variables or other intermediate information during execution of instructions to be executed by processor modules 210 and 230, respectively. Memory modules 216 and 234 may each include non-volatile memory for storing instructions to be executed by processor modules 210 and 230, respectively.

[0034] The network communications module 218 generally represents the hardware, software, firmware, processing logic, and / or other components of the BS 202 that enable bidirectional communications between the BS transceiver 210 and other network components and communications nodes configured to communicate with the BS 202. For example, the network communications module 218 may be configured to support Internet or WiMAX traffic. In a typical deployment, without limitation, the network communications module 218 provides an 802.3 Ethernet interface so that the BS transceiver 210 may communicate with conventional Ethernet-based computer networks. As such, the network communications module 218 may include a physical interface for connection to a computer network (e.g., a mobile switching center (MSC)). As used herein with respect to specified operations or functions, the terms “configured for,” “configured to,” and conjugations thereof, refer to devices, components, circuits, structures, machines, signals, etc. that are physically constructed, programmed, formatted, and / or arranged to perform the specified operations or functions.

[0035] 3 depicts an exemplary carrier phase positioning configuration according to the present implementation. As illustrated by way of example in FIG. 3, the exemplary carrier phase positioning configuration 300 may include at least base stations 310 and 320, transmissions 312 and 322 to and from the UE, a transmitted integer portion of the carrier phase 314, the UE 330, and a fractional portion of the carrier phase 332.

[0036] An application scenario for carrier phase-based positioning is described. For example, for a user equipment (UE), e.g., a target device, the carrier phase measured on a signal from a gNB is: [ka]

[0037] where λ=c / f is the wavelength of the radio signal (c is the speed of light and f is the carrier frequency of the radio wave transmitted by the transmitter), N is the integer part of the carrier phase (the number of complete wavelengths exchanged between the transmitter and receiver), φ is the carrier phase, and φ / (2π) indicates the fractional part of the carrier phase, D is the distance between the UE and the gNB (LOS distance), and w is the measurement noise.

[0038] 4 depicts an exemplary carrier phase positioning configuration using a positioning reference unit (PRU) according to this implementation. As illustrated by way of example in FIG. 4, the exemplary carrier phase positioning configuration using a PRU 400 can include at least a fixed UE 410 and transmissions 420 and 422 to and from the fixed UE.

[0039] Carrier phase positioning using a PRU is described. For more accurate evaluation, carrier phase positioning allows the system to incorporate a PRU to assist in location measurement for a target device. For each pair of gNB and UE, an equation referencing the relationship between measured distance and carrier phase is summarized in Equation 1. Some techniques utilize double differences between different UEs and gNBs to mitigate or eliminate the side effects of measurement errors and further achieve better positioning performance.

[0040] At least one aspect is directed to determining a measurement period using a measurement gap. In one TDOA positioning procedure, when the physical layer receives the last NR-TDOA-ProvideAssistanceData message and the NR-TDOA-RequestLocationInformation message from the LMF, the UE determines the measurement period T RSTD,Total During this time, it shall be possible to measure multiple Downlink (DL) Reference Signal Time Difference (RSTD) measurements, defined as follows: [ka]

[0041] In the formula, max() is an operation on the maximum value. For example, T RSTD,i is the measurement period for PRS RSTD measurements in positioning frequency tier i, as defined below: [ka]

[0042] For the carrier phase (CP) aided positioning procedure, the measurement period T CP,Total The DL CP measurement during may be defined as follows: [ka]

[0043] In the formula, N RxBeam,i is the UE Rx beam sweep factor, CSSF PRS,i is the carrier-specific scaling factor for NR PRS-based positioning measurements in positioning frequency layer i, and K p,PRS,i is a scaling factor for measuring in the measurement gap pattern to which the positioning frequency layer is associated, [ka] is the maximum number of DL PRS resources in the positioning frequency layer i configured in a slot, and L available_PRS,i is T available_PRS,i the duration of available PRS in positioning frequency stratum i to be measured during N sample is the number of PRS CP measurement samples, and T last,i is the measurement duration for the last PRS CP sample in positioning frequency layer i, and T effect,i is the periodicity of PRS CP measurement in positioning frequency layer i. By using this method, the UE can measure the carrier phase of the PRS within the CP measurement period, and the positioning efficiency can be improved. For the carrier phase (CP)-aided positioning procedure, the measurement period T CP,TotalThe DL CP measurement during may be defined as follows: [ka] During the ceremony, [ka] And, In the formula, K carrier_PRS is a scaling factor for PRS-based NR positioning measurements in RRC_INACTIVE, and N RxBeam,i is a scaling factor for the Rx beam sweep, [ka] is the maximum number of DL PRS resources of positioning frequency layer i configured in a slot, N′ is the UE capability in terms of the number of DL PRS resources that can be processed in a slot, and L available_PRS,i is T PRS,i the duration of the PRS available for measurement within the positioning frequency stratum i to be measured during N sample is the number of PRS CP measurement samples, and T last is the measurement duration for the last PRS CP sample, including sampling and processing time, and T effect,i is the periodicity of the PRS CP measurements in positioning frequency tier i.

[0044] For example, the PRS processing capability for CP measurements can be the same or different from that for RSTD measurements. For example, the PRS processing capability for CP measurements can be the same or different from that for RSTD measurements, and the UE can cp The duration of DL-PRS symbols in ms that can be processed per ms, N cp The PRS processing capabilities for CP measurements may be reported, and the report may contain one or more information elements (IEs). For example, the report may include N cp For example, the report may include an IE that includes or corresponds to a value for T cpFor example, T effect,i is the periodicity of PRS CP measurements in positioning frequency tier i, defined as follows: [ka]

[0045] For example, T i is defined above as T cp corresponds to the value of (T CP,i In the calculation equation, N is the number of cp corresponds to the value of

[0046] For example, PEG is CP,i A scaling factor k for measurements on the same PRS resource with multiple Rx PEGs (phase error groups) can be added to the calculation equation. multiPEG,i becomes: [ka] Other parameters [ka] can be the same as that of the RSTD measurement.

[0047] For example, the UE may report scaling factors for RSTD and CP measurements. This report may contain various IEs. For example, the report may contain an IE that includes or corresponds to a scaling factor for RSTD measurements. For example, the report may contain an IE that includes or corresponds to a scaling factor for CP measurements.

[0048] For example, the total measurement period for PFL i can be defined as: [ka]

[0049] The total measurement period for all PFLs T_(RSTD_CP,Total) is defined as follows: [ka]

[0050] For example, all PFL T RSTD_CP,Total The total measurement period for can be calculated as follows: [ka]

[0051] The scaling factor is between 0 and a preconfigured value.

[0052] For CP-assisted positioning, the UE can measure the CP along with other attributes. For example, the UE can report the PRS processing capability for measuring the CP and other attributes. For example, the report can include the duration N of the DL-PRS symbol in ms. combination For example, the UE may include T combination The report may contain various IEs. For example, the report may contain N combination For example, the report may include an IE that includes or corresponds to a value for T combination For example, the report may contain an IE including or corresponding to a measurement item. For example, the other attributes may include one of the following: RSTD, RSRP, RSRPP, UE Rx-Tx difference, and other measurement options. For example, the UE may specify a measurement period T combined,Total During this time, multiple DL PRS measurements can be taken, defined as follows: combined,i can be calculated using the combined UE measurement capabilities. [ka]

[0053] Optionally, the UE can report PRS processing capabilities within the PPW (without a measurement gap). For example, a PPW configuration for CP positioning may include two offsets for N2 and T2, and the report may contain various IEs. For example, the report may contain an IE including or corresponding to a value for N2. For example, the report may contain an IE including or corresponding to a value for T2. For example, the report may contain an IE including or corresponding to an offset for N2, i.e., ΔN2. For example, the report may contain an IE including or corresponding to an offset for T2, i.e., ΔT2. For example, the report may contain an IE including or corresponding to a measurement item.

[0054] For example, the UE capability for PPW can be (N2 + ΔN2, T2 + ΔT2). Compared to measuring a single attribute, the duration of measuring multiple attributes will be shorter or the period will be longer. Generally, ΔN2 is less than 0 and ΔT2 is greater than 0.

[0055] Measurement period T combined,Total can be defined as follows, where T RSTD_wo_gap,i is the measurement period for multiple PRS attribute measurements in positioning frequency tier i. [ka]

[0056] For example, compared to single attribute measurements, the UE can measure RSTD_CP,Total During this time, multiple attribute measurements can be measured (using RSTD as an example), defined as follows, where SF is a scaling factor between 1 and a predetermined value: [ka]

[0057] The above measurement period calculation process is performed within the measurement gap. For the case outside the measurement gap, the similar parameters are [ka] can also be used, and UE capability reporting related parameters (N cp , T cp , N combination , T combination ) can be included within the PPW (PRS Processing Window) processing capability.

[0058] FIG. 5 depicts an exemplary communication diagram according to the present implementation. As illustrated in FIG. 5 as an example, the exemplary communication diagram 500 may include at least a target UE 510, a PRU 520, a report transmission 522, an LMF 530, a PRU or PRS selection transmission 532, an error transmission 534, an estimation output 540, an error output 550, and error classification outputs 552, 554, and 556. In a CP-aided positioning process, there may be an antenna reference point (ARP) location error and an initial carrier phase error for the TRP transmitting antenna. If the ARP error or carrier phase corresponding to the same beam set for the TRP remains unchanged, an explicit ARP error or carrier phase error can be evaluated with the help of multiple PRUs.

[0059] 6 depicts an exemplary calibration architecture according to this implementation. As illustrated by way of example in FIG. 6, the exemplary calibration architecture 600 may include at least a TRP 610, PRS transmissions 620, 622, and 624, a PRU location 630, and a UE region 640.

[0060] For example, the first part may include PRU / PRS selection. Criteria for PRU selection to calibrate ARP error or carrier phase error include: 1) the selected PRU can receive the same PRS as the target UE; and 2) the selected PRU can be in the line-of-sight (LOS) direction of the TRP. For example, there are multiple PRUs located around the UE, and the TRP transmits multiple PRSs during the positioning process. PRU4 and PRU5 are selected as reference PRUs for calibrating error resources. In this scenario, PRU4, PRU5, and the target UE share the same ARP location error or carrier phase error. The LMF may send the selected PRU ID and PRS information to the PRU in an LTE Positioning Protocol (LPP) message containing various IEs. For example, the IEs may correspond to one or more of the PRU's ID, a PRS resource ID, a PRS resource set ID, and a PRS ID.

[0061] For example, the second part may include a PRU CP report. The PRU may report CP measurement results for the corresponding PRS resource ID, PRS resource set ID, and PRS ID in an LPP message, which may include various IEs. For example, the IEs may correspond to one or more of the PRU's ID, CP measurement results, PRS resource ID, PRS resource set ID, and PRS ID.

[0062] In the third part, the LMF can calculate the ARP location and CP error. For example, the third part can include an ARP error calculation (carrier phase error is omitted). Assume the TRP antenna location is (x, y), the ARP error is (ex, ey), and the actual ARP antenna location is (x, y) = (x + ex, y + ey). The following calculation explains the calculation details for (ex, ey). Assume the coordinates of PRU4 and PRU5 are (x4, y4) and (x5, y5), respectively. The measured PRS CPs of PRU4 and PRU5 are, [ka] The actual distance between the TRP and PRU4 is: [ka]

[0063] The actual distance between the TRP and PRU5 is: [ka]

[0064] where λ is the wavelength of the measured PRS and N is the integer part. Combining the above equations, the actual TRP antenna location (X, Y) can be calculated. The estimated APR error (ex, ey) can also be calculated.

[0065] For example, the third part can include error calculations (ARP errors are omitted). Assume that the actual antenna location of the TRP is (x, y), and the coordinates of PRU4 and PRU5 are (x4, y4) and (x5, y5), respectively. The measured PRS CPs of PRU4 and PRU5 are, respectively: [ka] The initial CP error for the TRP is [ka] Assuming that, the following calculations are [ka] For example, the actual distance between the TRP and PRU i (i=4 or 5) is given by: [ka] can be calculated. [ka]

[0066] For example, the third part may include ARP and CP error calculations. If both ARP and CP errors exist, at least three PRUs are required to calculate these error source values. There are three PRUs (PRU i, PRU j, PRU k) that meet the criteria for PRU selection (as listed in step 1), and the coordinates of PRU i, PRU j, and PRU k are (x i , y i ), (x j , y j ), (x k , y k ) The measured PRS CPs of PRU i, PRU j, and PRU k are respectively [ka] For example, the actual distance between the TRP and these PRUs is as follows, and by combining the following equations, the actual TRP antenna location (X, Y) and phase error [ka] can be calculated. [ka]

[0067] In the fourth part, the LMF may transmit the error to the UE. For UE-based positioning, the LMF may transmit various IEs to the target UE in the LPP message. For example, the IEs may include one or more of an ARP error (if applicable), a CP error (if applicable), a PRS ID, a PRS resource ID, and a PRS resource set ID. For example, the UE may obtain a more precise coordinate estimation result while calibrating the ARP error.

[0068] At least one aspect is directed to UL SRS-CP measurement requests and reporting. In 3GPP, the LMF would send measurement request signaling to an NG-RAN node to obtain the requested UL SRS measurement information. To obtain the UL SRS CP, the LMF can request for CP measurement results. The request can be added within a TRP measurement type that includes the UL SRS-CP option. Alternatively, the NG-RAN node would send measurement response signaling to the LMF to report the UL SRS measurement results. To report the UL SRSCP, the NG-RAN node can report the CP measurement results. The CP measurement results can be added within a TRP measurement result IE, where the IE includes one or more of the following: UL SRS-CP, additional route list and CP, UL SRS-CP quality, positioning SRS resource ID, and positioning SRS resource set ID. The UL SRS-CP quality can provide an estimate of the CP measurement uncertainty along with the following options: CP quality value and CP quality resolution.

[0069] 7 depicts an exemplary preferred subset architecture according to this implementation. As illustrated by way of example in FIG. 7, the exemplary preferred subset architecture 700 may include at least a preferred subset definition 710, a PRS priority option 720, a TRP priority option 730, a PRS UE-specific mode 740 and a non-UE-specific mode 742, a TRP UE-specific mode 750 and a non-UE-specific mode 752, and corresponding IDs 760, 762, 764, and 766. At least one aspect is directed to the preferred subset definition. In a CP-assisted positioning procedure, the LMF may provide the UE with a TRP or PRS subset and specify TRP / PRS information that the UE may measure with a higher priority, signifying associated DL-PRS resources that the target device should prioritize for DL-PRS CP measurement reporting within the measurement information.

[0070] FIG. 8 depicts an exemplary positioning configuration according to the present implementation. As illustrated in FIG. 8 as an example, the exemplary positioning configuration 800 can include at least a TRP 810 and PRS transmissions 820, 822, 824, 826, and 828. The TRP / PRS selection can satisfy the criterion that the transmission of the PRS between the TRP and the UE is an LOS path. For example, from the UE's perspective, TRP2 may have a higher CP measurement priority than TRP1. Also, among these transmitted PRSs, PRS3 and PRS4 may have a higher CP measurement priority than the other PRSs. For example, the TRP / PRS selection can include various options.

[0071] The first option may correspond to PRS selection. The system may define configuration information including dl-PRS-ResourcePrioritySubset1. When a UE receives a specific PRS, the CP will be measured with high priority. For UE-specific signaling, a PRS subset can be specified in NR-DL-PRS-Info, which contains dl-PRS-ResourcePrioritySubset1 for CP measurement priority. For example, the PRS subset can include or be associated with an IE including one or more of a PRS resource ID, a PRS resource set ID, and a PRS ID. For non-UE-specific signaling, the LMF may transmit the prioritized subset in other LPP messages, such as PRS configuration information. The prioritized subset can include an IE including one or more of a PRS resource ID, a PRS resource set ID, a PRS ID, and a UE ID.

[0072] The second option may correspond to TRP selection. The system may define configuration information such as dl-TRP-PrioritySubset. If the UE receives a PRS from this TRP, the CP will be measured with high priority. For UE-specific signaling, a TRP subset can be specified in NR-DL-PRS-Info, which contains dl-TRP-PrioritySubset for CP measurement priority. The TRP subset may include an IE for the PRS ID. Alternatively, the LMF may configure a priority indicator for each TRP to the UE. If the TRP and the current UE transmission path are an LOS path, the priority indicator can be set to 1; otherwise, the priority indication is 0. For non-UE-specific signaling, the LMF may transmit the priority subset in another LPP message, such as PRS configuration information. The priority subset may include one or more IEs including the PRS ID and the UE ID. In this way, positioning performance can be improved.

[0073] At least one aspect is directed to measurement threshold configuration. For example, the LMF can configure measurement thresholds for different positioning scenarios for the UE. For example, the configuration can include an IE for the measurement threshold. The threshold specifies whether the UE should report single or multiple measurement report results in a CP-assisted positioning procedure. For example, if the configured measurement threshold is X, the UE can measure / report RSTD along with the CP of the current PRS when RSRP>X. Otherwise, the UE can measure / report only one of these two measurement attributes. Using this method, PRSs with better quality can be measured, and signals with low RSRP will not be measured. In this way, carrier phase measurements can be more precise, further improving positioning accuracy.

At 1014, the method 1000 may receive a capability report indicating the capability of the wireless communication device. At 1016, the method 1000 may be received by a network node from the wireless communication device. At 1018, the method 1000 may be configured to measure the carrier phase of the reference signal within a period.

[0076] 11 depicts an exemplary method of carrier phase positioning according to the present implementation. At least one of the BS 102 or the UE 104 may perform the method 1100. At 1110, the method 1100 may report measurement results of a reference signal for positioning. At 1112, the method 1100 may be reported by a wireless communication device. At 1120, the method 1100 may receive configuration information of a reference signal for positioning. At 1122, the method 1100 may be received by a wireless communication node from a network node.

For example, in the wireless communication method, the capability report may further indicate a duration N of DL-PRS symbols in ms that the wireless communication device may process every T ms for carrier phase measurement.

[0085] For example, the wireless communication method may include applying, by the wireless communication device, a scaling factor for a phase error group (PEG) to a first period. For example, the wireless communication method may include reporting, by the wireless communication device, a first scaling factor for measuring a carrier phase of a reference signal. For example, the wireless communication method may include reporting, by the wireless communication device, a second scaling factor for measuring one or more other measurement attributes of the reference signal. For example, in the wireless communication method, in a second period, the wireless communication device is configured to measure the carrier phase, and the one or more other measurement attributes are defined according to the first scaling factor and / or the second scaling factor.

[0086] For example, the wireless communication method may include a second period that is applied for an ith one of a plurality of positioning frequency layers (PFLs). For example, the wireless communication method may include a second period that is applied for all of a plurality of positioning frequency layers (PFLs).

[0087] For example, a wireless communication method may include transmitting, by a wireless communication device, a capability report indicating its capability to measure the carrier phase of a reference signal along with one or more other measurement attributes.

For example, the method may include a capability report indicating at least one of: (1) a duration N of a DL-PRS symbol in ms that the wireless communication device may process every T ms; (2) an offset with respect to N and T; or (3) one or more measurement attributes.

[0088] For example, the wireless communication method may include a measurement attribute comprising RSTD, Reference Signal Received Power (RSRP), Reference Signal Received Path Power (RSRPP), UE Rx-Tx Difference, or a combination thereof. For example, the wireless communication method may include applying, by the wireless communication device, a scaling factor for measuring one or more other measurement attributes in a first period.

For example, in the wireless communication method, the configuration information may include at least one of 1) ARP (Antenna Reference Point) location error, 2) carrier phase error, 3) PRS ID, 4) PRS resource ID, and 5) PRS resource set ID.

[0089] For example, the wireless communication method may include reporting, by a wireless communication node, a measurement result of a reference signal for positioning to a network node.
