Abstract

A wireless communication method for use in a wireless terminal is disclosed, wherein the wireless communication method includes transmitting positioning status information to a wireless network node in a physical uplink channel.

Description

[0001] This document relates generally to wireless communications.

[0002] Figure 1 The basic principle steps involved in the positioning system, positioning measurement and position estimation are shown and are briefly summarized below.

[0003] DL PRS (Downlink Positioning Reference Signal) and measurement requests are configured by the core network entity, ie, Location Management Function (LMF), which are transmitted to the UE (User Equipment) and are transparent to the serving positioning node.

[0004] The serving positioning node and the neighbor positioning nodes will also be informed about the DL PRS configuration, which should be transmitted by the corresponding positioning nodes.

[0005] Subsequently, the UE receives the DL PRS configured by the LMF.

[0006] Then, the UE transmits the UL RS configured by the serving positioning node.

[0007] Next, the UE performs position estimation and / or measurement results based on the reference signal.

[0008] Finally, the UE reports the position estimation and / or measurement results to the core network entity, which is transparent to the serving positioning node.

[0009] However, there are some drawbacks in the current design of positioning status information reporting, such as frequent signaling interactions between the UE and LMF, large delays in positioning information reporting, and / or the UE can only report position estimates or measurement results to the core network entity.

[0104] Generally, according to an embodiment, positioning measurements or position estimates may be transmitted (e.g., reported) in one or more physical channels (e.g., a physical uplink control channel (PUCCH) and / or a physical uplink shared channel (PUSCH)) to overcome one or more of the above-mentioned problems of the prior art.

[0105] Example 1

[0106] According to an embodiment, a positioning state information (PSI) report may be transmitted on the PUCCH. That is, at least one of the following position estimates may be reported in the PSI report on the PUCCH: the UE's latitude (degrees), the UE's longitude (degrees), the UE's altitude, an uncertainty region for the UE's position, a confidence level for the uncertainty region, a relative position (e.g., the UE's coordinates relative to a reference point), the UE's horizontal velocity, the vertical velocity, and the uncertainty of the velocity (e.g., associated with the horizontal velocity and / or the vertical velocity).

[0107] According to an embodiment, by reporting PSI including position estimate on PUCCH, the position of the UE can be periodically reported with low latency. In addition, PUCCH is more reliable than other channels because of its small payload.

[0108] Example 2

[0109] According to an embodiment, the PSI report may be transmitted on the PUSCH. That is, the UE may be configured to report position estimation and / or measurement results on the PUSCH.

[0110] The position estimate may refer to at least one of the following position and velocity information: the UE's latitude (degrees), the UE's longitude (degrees), the UE's altitude, the uncertainty area of the UE's position, the confidence level of the uncertainty area, the relative position (e.g., the coordinates of the UE relative to a reference point), the horizontal velocity, the vertical velocity, and the uncertainty of the velocity.

[0111] The measurement result may refer to at least one of the following information: primary measurement information and additional measurement information. In an embodiment, multiple DL PRS resources may be configured for each positioning node, and the network may require the UE to report one or more additional measurements based on different DL PRS resources.

[0112] The main measurement information may include at least one of the following information: positioning node identification (ID) information, RS index used for measurement, timestamp used for measurement, positioning measurement information (e.g., DL PRS reference signal received power (RSRP), DL reference signal time difference (RSTD) and UE receive-transmit (Rx-Tx) time difference), measurement quality (e.g., measurement can be obtained from multiple receptions, so the measurement quality may include the average value of the measurement, the standard deviation of the measurement and the confidence level of the measurement), additional path information (e.g., when receiving DL PRS, the UE may be required to report a specific path time in addition to the first detected path time, where the measurement quality of the additional path may also need to be reported), and UE reception beam information (e.g., beam information of the RS received for measurement).

[0113] Additional measurement information may include the RS index (of the RS) used for measurement, the timestamp used for measurement, measurement quality, additional path information, and it may also be necessary to report UE receive beam information in the additional measurement information. The definitions of DL PRS RSRP, DL RSTD, and UE Rx-Tx time difference are as follows:

[0114] - DL PRS reference signal received power (DL PRS-RSRP) is defined as the linear average of the power contributions (in [W]) of the resource elements carrying the DL PRS reference signal configured for RSRP measurement within the considered measurement frequency bandwidth.

[0115] - DL Reference Signal Time Difference (DL RSTD) is the DL relative timing difference between positioning node j and reference positioning node i, which is defined as T SubframeRxj -T SubframeRxi , where T SubframeRxj is the time when the UE starts receiving a subframe from positioning node j, and T SubframeRxi is the time when the UE starts receiving a subframe from positioning node i, which is closest in time to the subframe received from positioning node j. Multiple DL PRS resources can be used to determine the start of a subframe from a positioning node.

[0116] -UE Rx–Tx time difference is defined as T UE-Rx –T UE-TX , where T UE-Rx is the timing of the downlink subframe #i received by the UE from the positioning node, which is defined by the first detected path time, and T UE-TX is the timing at which the UE transmits an uplink subframe #j that is closest in time to the subframe #i received from the positioning node. A plurality of DL PRS resources may be used to determine the start of one subframe of the first arrival path for the positioning node.

[0117] According to an embodiment, by transmitting PSI in PUSCH, PSI feedback can be triggered whenever needed (eg, PUSCH can be triggered dynamically). In addition, because PUSCH is equipped with a large payload, the network can require the UE to report position estimates or measurement results in PUSCH.

[0118] Example 3

[0119] According to an embodiment, the PSI report may be divided into two parts. That is, a PSI report may be divided into two parts, wherein, once configured by higher layer signaling, the bit width of the first part is fixed, and the bit width of the second part is indicated by the first part.

[0120] According to an embodiment, the first part of the PSI report may have at least one of the following: an indication of the number of reported positioning nodes or the number of reported positioning node pairs for DL RSTD measurements, an indication of the number of reported additional paths or whether additional paths are reported, an indication of the number of additional measurements or whether additional measurements are reported in the second part, an indication of whether measurement quality is reported, an indication of whether a timestamp is reported, and an indication of whether UE receive beam information is reported.

[0121] According to an embodiment, the second part of the PSI report may have at least one of the following as indicated by the first part: some information of the main measurement and / or some information of one or more additional measurements.

[0122] According to an embodiment, the second part of the PSI report may be divided into one or more subparts, eg, a first subpart for the main measurement, a second subpart for the first additional measurement, a third subpart for the second additional measurement, and so on.

[0123] Example 3-1

[0124] According to an embodiment, a two-part PSI report for DL PRS RSRP measurement may include a first part of a PSI report having at least one of the following: the number of reported positioning nodes is 3; no additional measurements are reported; no timestamps are reported; measurement quality is reported; and UE receive beam information is not reported.

[0125] In this embodiment, the PSI report for DL PRS RSRP measurement may include a second part of the PSI report having the following contents:

[0126] - Positioning node ID information of the first positioning node; DL PRS RSRP value; DL PRS index used for measurement; and measurement quality of DL PRS RSRP;

[0127] - Positioning node ID information of the second positioning node; DL PRS RSRP value; DLPRS index used for measurement; measurement quality of DLPRS RSRP; and

[0128] - Positioning node ID information of the third positioning node; DL PRS RSRP value; DLPRS index used for measurement; and measurement quality of DLPRS RSRP.

[0131] In this embodiment, the PSI report for DL RSTD measurement may include a second part of the PSI report having the following contents:

[0132] - a first subsection comprising at least one of the following:

[0133] a. A primary measurement of the first pair having at least one of the following information:

[0136] The second pair of reference positioning node ID information; the second pair of neighboring positioning node ID information; the DL RSTD value; the DL PRS index from the reference positioning node used for measurement; the DL PRS index from the neighboring positioning node used for measurement; the first additional path time of the reference positioning node; the second additional path time of the reference positioning node; the first additional path time of the neighboring positioning node; and the second additional path time of the neighboring positioning node.

[0137] - A second subsection comprising at least one of the following:

[0138] a. A first additional measurement of the first pair having at least one of the following information (wherein the reference positioning node ID information and the neighbor positioning node ID information associated with the measurement are the same as the primary measurement of the first pair):

[0139] DL RSTD value; DL PRS index from the reference positioning node used for measurement; DL PRS index from the neighboring positioning node used for measurement; first additional path time of the reference positioning node; second additional path time of the reference positioning node; first additional path time of the neighboring positioning node; and second additional path time of the neighboring positioning node; and

[0140] b. A first additional measurement of the second pair having at least one of the following information (wherein the reference positioning node ID information and the neighbor positioning node ID associated with the measurement are the same as the primary measurement of the second pair):

[0141] DL RSTD value; DL PRS index from the reference positioning node used for measurement; DL PRS index from the neighboring positioning node used for measurement; first additional path time of the reference positioning node; second additional path time of the reference positioning node; first additional path time of the neighboring positioning node; and second additional path time of the neighboring positioning node.

[0142] - A third subsection comprising at least one of the following:

[0143] a. A second additional measurement of the first pair having at least one of the following information (wherein the reference positioning node ID information and the neighbor positioning node ID information associated with the measurement are the same as the primary measurement of the first pair):

[0144] DL RSTD value; DL PRS index from the reference positioning node used for measurement; DL PRS index from the neighboring positioning node used for measurement; first additional path time of the reference positioning node; second additional path time of the reference positioning node; first additional path time of the neighboring positioning node; and second additional path time of the neighboring positioning node; and

[0145] b. A second additional measurement of the second pair having at least one of the following information (wherein the reference positioning node ID information and the neighbor positioning node ID information associated with the measurement are the same as those of the primary measurement of the second pair):

[0146] DL RSTD value; DL PRS index from the reference positioning node used for measurement; DL PRS index from the neighboring positioning node used for measurement; first additional path time of the reference positioning node; second additional path time of the reference positioning node; first additional path time of the neighboring positioning node; and second additional path time of the neighboring positioning node.

[0147] In an embodiment, the second part of the PSI report may be divided into more subparts, for example three subparts, where the first subpart is for the main measurement, the second subpart is for the first additional measurement, and the third subpart is for the second additional measurement.

[0148] According to an embodiment, by adopting a two-part PSI report for reporting PSI, the report content (which is indicated in the first part of the PSI) can be determined by the UE. In addition, the UE can report some additional path information for more accurate positioning. In addition, the UE can report some additional measurements, which allows the network to decide which measurement can be used to locate the UE. Last but not least, different parts of the PSI report can be mapped to the PUSCH in different orders, for example, the most important part can be mapped to the most significant bit.

[0149] Example 4

[0150] According to an embodiment, PSI report processing priority may be given. That is, if PSI (report) and channel state information (CSI) (report) are triggered by the same signaling, the UE may be instructed to process only PSI (eg, prioritize PSI (report)).

[0151] In an embodiment, once semi-persistent PSI or aperiodic PSI reporting is triggered, the UE may be instructed to stop processing all other ongoing CSI reports.

[0152] In an embodiment, the UE's computation resource usage may depend on the configuration of the PSI report, for example, the total number of positioning nodes and the total number of DL PRS resources configured for obtaining the PSI report.

[0153] In an embodiment, the configuration of PSI reporting may exceed the UE processing capability. In this case, the UE may select some positioning nodes indicated with high priority for reporting and / or the UE may select some DL PRS resources indicated with high priority.

[0154] According to an embodiment, PSI report feedback priority may be given. That is, if some CSI reports and PSI reports are multiplexed on the same physical channel, the PSI report may be indicated with the highest priority.

[0155] In an embodiment, for two-part PSI reporting, the PSI report is mapped onto the PUSCH according to the following order:

[0156] The mapping priority from high priority to low priority is the first part PSI, the first subpart in the second part PSI, the second subpart of the second part PSI, the third subpart of the second part PSI, ...

[0157] In an embodiment, for a two-part PSI report, if the PUSCH payload is insufficient for the entire PSI report, the UE may omit a portion of the second part of the PSI report (i.e., at least one subpart may be omitted). In an embodiment, subparts with lower mapping priority are omitted first. In other words, the second part of the PSI report may be omitted in ascending order from the last subpart to the first subpart.

[0158] For example, the second part of the PSI report includes 3 subparts. The third subpart in the second part of the PSI report will be omitted first, then the second subpart in the second part of the PSI report will be omitted, and finally the first subpart in the second part of the PSI report will be omitted.

[0159] In an embodiment, when there is an urgent positioning requirement, the priority of PSI may be higher than that of CSI.

[0160] Based on embodiment 4, the UE may process the PSI report according to its priority, which may ensure more accurate measurement by using limited UE capabilities.

[0161] Example 5

[0162] Figure 4 The usage of time slots for preparing PSI reports according to an embodiment of the present disclosure is shown.

[0163] In an embodiment, since the bandwidth / center frequency / SCS (subcarrier spacing) of the DL PRS may differ from that of the serving cell, the DL PRS may only be received by the UE during measurement gaps. The network configures the measurement gap pattern, with the measurement gap length represented by MGL and the periodicity represented by MGRP (Measurement Gap Repetition Period). In this embodiment, the timing of transmitting the PSI report may take into account the measurement gap configuration.

[0164] In an embodiment, the time gap for preparing the PSI report may satisfy one of the following conditions: the time gap T0 may not be less than a predetermined threshold, and / or the time gap T1 may not be less than a predetermined threshold. Note that the time gap T0 is the time gap between the time when the last RS used for the PSI report is received and the time when the PSI report is sent, and the time gap T1 is the time gap between the end time of the measurement gap in which the last RS used for the PSI report is located and the time when the TSI report is transmitted.

[0165] The threshold may be determined according to the UE capability, and one of the above two options may be selected depending on the UE capability.

[0166] In an embodiment, when the UE is able to process RS within the measurement gap, the restriction associated with the time gap T0 may be employed.

[0167] In an embodiment, when the UE can only buffer one or more RSs received within a measurement gap, the restriction associated with the time gap T1 may be employed.

[0168] Based on UE capabilities, the UE may select restrictions associated with one of the time slots T0 or T1 for preparing the PSI report.

[0169] Generally, according to an embodiment, when measurement of the UE Rx-Tx time difference is required, the DL RS and UL RS used for the measurement can be considered to be activated by the same MAC CE and / or triggered by the same DCI.
