为详细说明本申请实施例提供的验证终端位置的方法，以下将结合几个具体的实施例进行说明。
实施例一
该实施例主要介绍终端(UE)上报的额外信息，该额外信息用于网络侧设备验证终端的位置信息。
该实施例中，UE可以报告一些附加测量(即额外信息)用于UE位置的验证，其中UE位置可以是基于GNSS估计的UE位置和/或UE基于非GNSS定位方法计算的UE位置。
对于上行(Uplink，UL)定位，是NR节点(NR Node B，gNB)在探测参考信号(Sounding Reference Signal，SRS)上进行定位测量，在这种情况下，UE不必向gNB或LMF报告信息，因此通常无需考虑这种情况。
对于下行(Downlink，DL)定位，是UE在定位参考信号(Positioning Reference Signals，PRS)上进行测量，可以是UE辅助定位(UE-assisted positioning)，也可以是基于UE的定位(UE-based positioning)。在UE辅助定位中，UE可以报告计算位置所需的具体信息，其中包括额外信息；在基于UE的定位中，UE可以报告位置信息，还可以报告额外信息。
在一些实施例中，对于NTN情况下基于UE的定位，如DL-TDOA定位方法，具体可以是基于DL RSTD定位，或基于DL-PRS-RSRP定位，UE可以进一步汇报至少如下一种信息：
1)用于位置估计的每个PCI，GCI和TRP标识的测量信息质量(the measurement information quality of each{PCI,GCI,and TRP ID}selected for location estimation)。
2)国家信息。

8)用于位置估计选择的每个PCI，GCI和TRP标识的每个测量质量(Quality for each measurement,for each{PCI,GCI,and TRP ID}selected for location estimation)。
在一些实施例中，对于NTN情况下基于UE的定位方法，如DL-AoD定位方法，具体可以是基于DL PRS RSRP定位，UE可以进一步汇报至少如下一种信息：
1)用于位置估计的每个PCI，GCI和TRP标识的测量信息质量，比如参考信号接收功率(Reference Signal Receiving Power，RSRP)，参考信号接收质量(Reference Signal Receiving Quality，RSRQ)。
2)国家信息。
3)每次测量的PCI，GCI或TRP标识(PCI,GCI和TRP ID for each measurement)。
4)下行PRS RSRP(DL-PRS-RSRP measurement)。
5)时间戳信息(Time stamp of the measurements)。
在一些实施例中，对于NTN情况下基于终端或终端独立(UE-based/standalone)的TBS定位方法，UE可以进一步汇报至少如下一种信息：
1)国家信息。
2)TBS测量量(TBS measurements)，可以是代码相位测量量(code phase(MBS))。
3)每次测量的测量质量参数(Measurement quality parameters for each measurement)。
在一些实施例中，对于NTN情况下基于终端或终端独立的GNSS定位(UE assisted GNSS positioning)方法，UE可以进一步汇报至少如下一种信息：
1)国家信息。
2)代码相位测量量，也叫做拟极差(Code phase measurements,also called pseudorange)。

6)每次测量的测量质量参数(Measurement quality parameters for each measurement)。
7)其他与非GNSS相关的测量信息(Additional,non-GNSS related measurement information)。
在一些实施例中，对于NTN情况下基于终端或终端独立的气压传感器定位(Barometric pressure sensor positioning)方法，UE可以进一步汇报至少如下一种信息：
1)国家信息。
2)大气压力传感器测量量(Barometric pressure sensor measurements)。
在一些实施列中，UE为NTN主小区汇报终端专属绝对TA，该TA包括定时预补偿(UE specific absolute TA including timing precompensation(16bits)for PCell in NTN)。
在一些实施例中，UE对于不同小区(cell)或者不同服务卫星(satellite)提供多个不同汇报，也即所述终端对不同的小区或服务卫星上报的所述额外信息不同。
在一些实施例中，UE可以基于RRC，媒体接入控制控制单元(Medium Access Control Control Element)MAC CE或者LPP信令汇报额外信息。
在一些实施例中，UE触发性的上报额外用信息。比如，引入一个“network Verification”子域(subfield)，用于指示UE是否需要额外向网络汇报用于网络验证UE位置的额外信息，具体如下示例所示。
触发报告(triggered Reporting)信元：此信元(Information element，IE)表示请求触发报告，并包含以下子域(triggered Reporting：This IE indicates that triggered reporting is requested and comprises the following subfields)：
1)小区变更(cell Change)域：如果此子域设置为真(TRUE)，则每次主小区发生更改时，目标设备都会提供请求的位置信息(cell Change:If this field is set to TRUE,the target device provides requested location information each time the primary cell has changed)。
2)报告持续时间(reporting Duration)域：指示触发报告的最大持续时间，单位可以为秒。如果被设置为0，则被认为是无限持续时间。目标设备应在报告持续时间内或在收到LPP中止或LPP错误消息之前继续触发报告(reporting Duration:Maximum duration of triggered reporting in seconds.A value of zero is interpreted to mean an unlimited(i.e."infinite")duration.The target device should continue triggered reporting for the reporting Duration or until an LPP Abort or LPP Error message is received)。
3)网络验证(network Verification)域：如果此子域设置为真(TRUE)，则目标设备(如UE)将为网络提供额外信息，以验证UE的位置(network Verification:If this field is set to TRUE,the target device provides additional information for network to verify the UE location)。
在一些实施例中，UE被请求上报额外信息，可以基于特定的定位方法或者使用公共的字段。比如，对于下行TDOA引入一个“nr-network Verification-Request”字段，用于 指示UE是否被请求额外向网络汇报用于网络验证UE位置的信息，具体如下所示。
再比如，在位置信息请求公共信元(Common IEs Request Location Information)里引入一个“nr-network Verification-Request”字段，用于指示UE是否被请求额外向网络汇报用于网络验证UE位置的额外信息，具体如下所示。
在一些实施例中，UE周期性的上报额外用于网络验证UE位置的额外信息。比如，引入NTN-specific的上报间隔(reporting interval)和/或上报数量(reporting amount)，具体如下所示。
周期报告(periodical Reporting)信元，该信元表明需要周期性报告，包括以下子域(periodical Reporting，This IE ind icates that periodic reporting is requested and comprises the following subfields)：
1)报告数量(reporting Amount)域，表示请求的周期位置信息报告的数量。枚举值 对应于1、2、4、8、16、32、64或无限/未定义的报告。如果报告数量域为“无限/未定义”，目标设备应继续周期报告直到收到LPP中止消息。发送方不得使用值“ra1”(reporting Amount indicates the number of periodic location information reports requested.Enumerated values correspond to 1,2,4,8,16,32,64,or infinite/indefinite number of reports.If the reporting Amount is'infinite/indefinite',the target device shou-ld continue periodic reporting until an LPP Abort message is received.The value'ra1'shall not be used by a sender)。
2)NTN报告数量(reporting Amount NTN)域，表示为NTN请求的周期位置信息报告的数量。枚举值对应于1、2、4、8、16、32、64或无限/未定义的报告。如果NTN报告数量域为“无限/未定义”，目标设备应继续周期报告直到收到LPP中止消息。发送方不得使用值“ra1”(reporting Amount NTN indicates the number of periodic location information reports requested for NTN.Enumerated values correspond to 1,2,4,8,16,32,64,or infinite/indefinite number of reports.If the reporting Amount is'infinite/indefinite',the target device shou-ld continue periodic reporting until an LPP Abort message is received.The value'ra1'shall not be used by a sender)。
3)报告间隔(reporting Interval)域，表示位置信息报告与第一个位置信息报告的响应时间要求之间的间隔。枚举值ri0-25、ri0-5、ri1、ri2、ri4、ri8、ri16、ri32、ri64分别对应于1、2、4、8、10、16、20、32和64秒的报告间隔。如果在目标设备能够获得新的测量值或新的位置估计值之前报告间隔过期，则需要不包含测量值或位置估计值的测量报告。发送方不得使用“no Periodical Reporting”值(reporting Interval indicates the interval between location information reports and the response time requirement for the first location information report.Enumerated values ri0-25,ri0-5,ri1,ri2,ri4,ri8,ri16,ri32,ri64correspond to reporting intervals of 1,2,4,8,10,16,20,32,and 64seconds,respectively.Measurement reports containing no measurements or no location estimate are required when a reporting Interval expires before a target device is able to obtain new measurements or obtain a new location estimate.The value'no Periodical Reporting'shall not be used by a sender)。
4)NTN报告间隔(reporting Interval NTN)域，表示位置信息报告与NTN的第一个位置信息报告的响应时间要求之间的间隔。枚举值ri0-25、ri0-5、ri1、ri2、ri4、ri8、ri16、ri32、ri64分别对应于1、2、4、8、10、16、20、32和64秒的报告间隔。如果在目标设备能够获得新的测量值或新的位置估计值之前报告间隔过期，则需要不包含测量值或位置估计值的测量报告。发送方不得使用“no Periodical Reporting”值(reporting Interval NTN indicates the interval between location information reports and the response time requirement for the first location information report for NTN.Enumerated values ri0-25,ri0-5,ri1,ri2,ri4,ri8,ri16,ri32,ri64correspond to reporting intervals of 1,2,4,8,10,16,20,32,and64seconds,respectively.Measurement reports containing no measurements or no location estimate are required when a reporting Interval expires before a target device is able to obtain  new measurements or obtain a new location estimate.The value'no Periodical Reporting'shall not be used by a sender)。
在一些实施例中，网络额外配置UE是否需要额外汇报用于网络验证UE位置的额外信息。比如，在额外信息(Additional Information)信元里面引入网络验证位置的附加信息(Additional Information For Network Verified Location)参数用于指示是否UE是否需要额外汇报用于网络验证UE位置的额外信息，具体如下所示。
再比如，在位置信息请求公共信元(Common IEs Request Location Information)里面引入NTN额外信息(additional Information NTN)信元，该信元里面列出指示是否需要UE额外指示一些用于NTN验证UE位置的额外信息，具体如下所示。

在一些实施例中，网络额外配置NTN专属的定位调度定位请求信息。比如，引入NTN调度位置时间(scheduled Location Time NTN)字段，针对NTN网络定位做额外配置，具体如下所示。
再比如，位置信息请求公共信元(Common IEs Request Location Information)引入Scheduled Location Request NTN-r18字段，针对NTN网络定位做额外配置，具体如下所示。
在一些实施例中，网络额外配置NTN specific的请求(request)信息，可以是基于每种定位方法的，也可以是公共(common)的。比如，整个Common IEs Request Location Information可以是NTN专属的，引入Common IEs Request Location Information NTN。
在一些实施例中，UE汇报额外汇报用于NTN网络验证UE位置的信息的能力。比如，对于OTDOA定位方法，UE可以在OTDOA-Provide Capabilities信元里通过Additional Info For Net Verification Report字段汇报是否有能力在NTN网络向网络汇报用于网络验证UE位置的额外信息，具体如下所示。

实施例二
该实施例主要介绍NTN专属(specific)定位信号。该实施例引入NTN specific的定位信号，以提高UE定位精度。比如，提高上行定位信号在时间上的发送密度，以及汇报频率，从而提高UE定位精度已经UE位置的更新频率。
在一些实施例中，NTN specific定位信号可以是如下之一：1)上行定位信号，比如上行SRS信号专门用于NTN场景下的定位；2)下行定位信号，比如下行PRS信号专门用于NTN场景下的定位。
在一些实施例中，相对于TN定位信号，NTN specific定位信号可以具有如下一种或者多种特性：
1)时间周期范围。
2)频率大小范围。
3)重复(Repetition)次数范围。比如用于定位的PRS信号最大repetition次数可以增加。
4)Comb大小。比如,支持某些符号(symbol)上PRS所在物理资源块(Physical Resource Block，PRB)(每个PRB有12个RE)上的所有资源单元(Resource Element，RE),具体如图3所示。再比如，对于上行SRS再引入在频域上更稀疏的RE匹配(mapping)，比如comb-12或者comb-24,具体如图4和图5所示。
5)使用某个固定的配置，包括时间配置，频域配置和序列配置的至少之一。比如，每个可用时隙的最后一个符号用于发送NTN定位信号。
对于NTN特别是低地球轨道(Low Earth Orbit，LEO)场景，卫星移动速度快，UE位置上报的频率较高，而且服务卫星切换频率也较高，频繁重新配置定位信号将产生较长延时和很多信令开销，该实施例可以减少时延，降低信令开销。
实施例三
该实施例主要通过额外信息验证通过GNSS定位估计的UE位置。
在一些实施例中,UE报告的用于验证基于GNSS定位估计的UE位置的附加信息独立于非GNSS定位过程。比如UE可以额外汇报服务小区或者邻区上的参考信号(比如SSB)的测量值。
实施例四
该实施例主要针对NTN网络，只允能使网络有足够位置验证信息的定位方法。可选地，对于NTN网络，只允许如下一种或者多种定位估计方法：
