技术领域
本公开涉及通信技术领域，尤其涉及一种测量上报及接收方法、装置及设备。
背景技术
为了获得终端的地理位置信息，现有技术中一种常见的终端定位方法是测量多个网络侧发设备到终端的下行离开角(Downlink Angle of Departure，DL-AoD)，利用多个网络侧发设备到终端的下行离开角，可以计算得到终端的位置。具体的，网络侧发送设备可以是基站或收发点(TRP，Transmission Reception Point)。
新无线(New Radio，NR，也被称为新空口)系统中，每个基站发送多个下行定位参考信号(Positioning Reference Signal，PRS)，每个定位参考信号经过赋形后指向不同的方向。终端测量每个波束的参考信号接收功率(Reference Signal Received Power，RSRP)，并向网络侧的定位服务器反馈每个波束的RSRP取值。定位服务器根据接收到的每个波束的RSRP取值，确定相应基站到终端的离开角，进而确定终端的位置信息。
图1给出了现有技术的下行离开角测量的原理示意图。图1中，终端14分别测量基站11、基站12和基站13中的多个波束。例如终端14测量基站11的3个波束，如波束15～17后，反馈每个波束对应的RSRP。定位服务器根据上述3个波束的RSRP，以及服务器已知的3个波束对应的发送角度，可以通过插值的方式获得基站11到终端14的到达角。类似的，基站12和基站13执行相同的操作。这样，定位服务器在获得多个基站到终端14的到达角后，可以采用已有的基于角度的算法计算得到终端的位置信息。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备 固有的其它步骤或单元。说明书以及权利要求中“和/或”表示所连接对象的至少其中之一。
本文所描述的技术不限于长期演进型(Long Time Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统以及NR系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(UltraMobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE 802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了NR系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用。
以下描述提供示例而并非限定权利要求中阐述的范围、适用性或者配置。可以对所讨论的要素的功能和布置作出改变而不会脱离本公开的精神和范围。各种示例可恰适地省略、替代、或添加各种规程或组件。例如，可以按不同于所描述的次序来执行所描述的方法，并且可以添加、省去、或组合各种步 骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
如前文所述的，现有技术的基于下行离开角的定位方案中，终端需要反馈其测量到的多个基站的波束的RSRP，且每个基站又分别包括有多个波束。例如，终端测量到M个基站，每个基站包含N个发送波束。这样终端需要反馈M×N个RSRP的取值。这些测量量的上报将占用较大的资源开销。
为了减少定位测量上报的资源开销，本公开实施例提供了一种测量上报方法，如图2所示，该方法在应用于终端侧时，包括：
步骤21，终端测量多个网络侧发送设备发送的定位参考信号，并根据同一网络侧发送设备发送的多个定位参考信号，确定该网络侧发送设备的离开角指示信息。
这里，上述网络侧发送设备具体可以基站和/或收发点(Transmission Reception Point，TRP)。通常，一个小区可以包括由多个TRP联合覆盖。终端可以测量多个网络侧发送设备发送的定位参考信号(PRS)，针对每个网络侧发送设备，根据该网络侧发送设备所发送的多个定位参考信号的测量结果(如RSRP)，确定该网络侧发送设备的离开角指示信息，从而可以获得多个网络侧发送设备各自的离开角指示信息。
步骤22，所述终端将所述多个网络侧发送设备的离开角指示信息发送给网络侧定位设备。
这里，网络侧定位设备可以是上述多个网络侧发送设备中的一个，例如，可以是其中的一个基站或TRP，还可以是设置于网络侧的定位服务器。终端将所获得的多个网络侧发送设备的离开角指示信息发送给网络侧定位设备，具体的，可以发送给网络侧的基站、TRP或定位服务器。在发送给定位服务器时，上述离开角指示信息可以经由终端的服务基站(TRP)转发至定位服务器。
通过以上步骤，本公开实施例可以将多个网络侧发送设备的离开角指示信息发送给网络侧定位设备，从而网络侧定位设备可以根据这些离开角指示信息，确定出终端的位置信息，实现对终端的定位。在上述测量上报方法中，终端不再需要上报多个网络侧发送设备的多个定位参考信号的RSRP的取值，而仅需要上报每个网络侧发送设备的离开角指示信息，从而可以大大减少定 位测量上报的资源开销，节约了信令资源。
本公开实施例中，在上述步骤21之前，终端还可以接收网络侧定位设备(如基站或TRP)发送的测量配置信息，所述测量配置信息包括有所述定位参考信号的配置信息和上报的测量量的配置信息。其中，所述定位参考信号的配置信息具体可以包括定位参考信号的时频域资源位置等信息，所述测量量包括有离开角指示信息。这样，所述终端根据所述定位参考信号的配置信息，可以对网络侧发送设备发送的定位参考信号进行检测和测量，以及，在进行测量时，根据上报的测量量的配置信息，进行针对性的测量上报。
本公开实施例中所述的离开角指示信息具体可以是以下信息中的一种或多种：离开角所对应的离开角索引；离开角的取值。其中，所述离开角的取值用于指示离开角的具体角度。所述离开角所对应的离开角索引用于指示离开角所对应的定位参考信号，由于离开角所对应的定位参考信号可能与网络侧发送设备发送的某一个定位参考信号相同，也可能与网络侧发送设备发送的所有定位参考信号均不同。因此，所述离开角索引具体可以采用某个已知的定位参考信号的索引+偏移量的方式进行表示，如采用网络侧发送设备发送的多个定位参考信号中的一个定位参考信号的索引(即参考索引)，以及，相对于所述参考索引的偏移量进行表示。当然，上述离开角索引也可以直接采用离开角索引的索引值表示。
在所述离开角索引采用所述参考索引和偏移量表示时根据本公开的至少一个实施例，上述步骤21中确定离开角指示信息时，具体可以包括：
A)所述终端可以根据多个网络侧发送设备发送的定位参考信号的参考信号接收功率(RSRP)，选择出满足预设条件的网络侧发送设备。
例如，根据定位所需要的网络侧发送设备的最少数量Y，按照各个网络侧发送设备发送的定位参考信号的最大RSRP的从高到低的排序，选择出前X个网络侧发送设备，这里X大于或等于Y，且小于或等于所述多个网络侧发送设备的总数量。这样可以在一定程度上减少终端的计算量。
又例如，根据各个网络侧发送设备发送的定位参考信号的最大RSRP的从高到低的排序，选择出最大RSRP大于预设门限的网络侧发送设备。这样可以保证所选择出的用于计算离开角指示信息的网络侧发送设备具有较高的 可靠性，进而保证计算出的离开角的准确性。
当然，本公开实施例也可以不作任何选择，从而在确定离开角指示信息时，利用所有网络侧发送设备的定位参考信号的RSRP。
B)针对每个选择出的网络侧发送设备，利用该网络侧发送设备发送的多个定位参考信号的索引和RSRP进行曲线拟合，根据拟合得到的曲线上的最大RSRP的位置点，确定该网络侧发送设备的离开角所对应的参考索引以及索引偏移量。
这里，可以采用曲线拟合的方式，获得拟合曲线，并找到拟合曲线上最大RSRP的位置点，该位置点对应于网络侧发送设备的离开角的离开角索引，从而可以将与该位置点相邻的网络侧发送设备发送的某个定位参考信号的索引作为所述参考索引，以及，根据该位置点与参考索引之间的距离，确定所述索引偏移量。
在所述离开角指示信息为离开角的取值时，根据本公开的另一些实施例，上述步骤21中确定离开角指示信息时，具体可以包括：
a)所述终端可以根据多个网络侧发送设备发送的定位参考信号的参考信号接收功率(RSRP)，选择出满足预设条件的网络侧发送设备。
b)针对每个选择出的网络侧发送设备，利用该网络侧发送设备发送的多个定位参考信号的索引和RSRP进行曲线拟合，根据拟合得到的曲线上的最大RSRP的位置点，确定该网络侧发送设备的离开角索引。
上述步骤a和b，与上述的步骤A和B相类似，这里不再赘述。
c)根据预先获得的网络侧发送设备所发送的每个定位参考信号对应的波束方向的角度信息，确定所述离开角索引对应的角度信息，得到该网络侧发送设备的离开角的取值。
这里，也可以利用该网络侧发送设备发送的多个定位参考信号的索引和各个定位参考信号对应的波束方向的角度信息进行曲线拟合，根据拟合得到的曲线上的所述离开角索引所对应的角度信息，确定该网络侧发送设备的离开角的取值。
另外，本公开实施例在上述确定离开角索引和离开角索引所对应的角度信息时，可以采用的曲线拟合方式包括但不限于线性拟合和高阶多项式拟合 等，本公开实施例对此不作具体限定。
为了便于计算离开角索引对应的角度信息，在上述步骤21之前，终端还可以接收网络侧发送设备发送的定位参考信号对应的波束方向的角度信息，以便于进行上述曲线拟合计算处理。
另外，本公开实施例在上述步骤22中，所述终端还可以将所述网络侧发送设备的离开角指示信息所对应的RSRP发送给网络侧定位设备，其中，所述网络侧发送设备的离开角指示信息所对应的RSRP为上述步骤b或B中拟合得到的曲线上的最大RSRP。这样，网络侧定位设备可以根据各个网络侧发送设备的离开角指示信息所对应的RSRP，从多个网络侧发送设备中选择出该RSRP大于预设质量门限的网络侧发送设备，利用所选择出的网络侧发送设备的离开角指示信息，进行终端的定位，这样可以减少计算量并提高定位结果的准确性。
请参照图3，本公开实施例提供的测量接收方法，应用于网络侧定位设备，该网络侧定位设备可以是多个网络侧发送设备中的一个，例如，可以是其中的一个基站或TRP，还可以是设置于网络侧的定位服务器。如图3所示，该方法包括：
步骤31，网络侧定位设备接收终端测量上报的多个网络侧发送设备的离开角指示信息。
这里，所述离开角指示信息包括以下信息中的至少一种：离开角所对应的离开角索引；离开角的取值。其中，所述离开角索引可以直接采用所述离开角索引的索引值表示，也可以采用网络侧发送设备发送的多个定位参考信号中的一个定位参考信号的参考索引，以及，相对于所述参考索引的偏移量来表示。
所述网络侧定位设备具体可以是网络侧的定位服务器和/或网络侧发送设备。其中，所述网络侧发送设备具体可以包括TRP和/或基站。在所述网络侧设备为定位服务器时，所述定位服务器可以接收经由服务基站(TRP)转发的所述终端上报的多个网络侧发送设备的离开角指示信息。
步骤32，所述网络侧定位设备根据所述多个网络侧发送设备的离开角指示信息，确定所述终端的位置信息。
这里，在所述离开角指示信息为网络侧发送设备的离开角的取值时，所述网络侧设备可以根据所述多个网络侧发送设备的离开角的取值，利用各种角度定位算法，确定所述终端的位置信息。具体的角度定位算法本公开实施例不作限定。
在所述离开角指示信息为离开角所对应的离开角索引时，所述网络侧设备可以根据每个网络侧发送设备的离开角所对应的离开角索引以及该网络侧发送设备所发送的每个定位参考信号对应的波束方向的角度信息，确定该网络侧发送设备的离开角索引对应的角度信息，得到该网络侧发送设备的离开角的取值；然后，根据所述多个网络侧发送设备的离开角的取值，利用角度定位算法，确定所述终端的位置信息。具体的，确定网络侧发送设备的离开角索引对应的角度信息，可以参考前文中的曲线拟合的处理方式，为节约篇幅，此处不再详述。
通过以上步骤，本公开实施例中网络侧定位设备只需要接收每个网络侧发送设备的离开角指示信息，而不需要接收每个网络侧发送设备发送的各个定位参考信号的RSRP，即可计算出终端的位置，从而可以大大降低定位过程中定位测量上报的资源开销。
另外，在上述步骤32中，如果是由网络侧的定位服务器根据所述多个网络侧发送设备的离开角指示信息，确定所述终端的位置信息，则在确定终端的位置信息之前，网络侧的定位服务器还可以接收网络侧发送设备上报的定位参考信号对应的波束方向的角度信息，以便于定位服务器据此进行终端定位。
另外，根据本公开的至少一个实施例，在上述步骤31之前，网络侧定位设备(如基站或TRP)还可以向所述终端发送测量配置信息，所述测量配置信息包括有所述定位参考信号的配置信息和上报的测量量的配置信息，所述测量量包括有离开角指示信息。这样所述终端根据所述定位参考信号的配置信息，可以对网络侧发送设备发送的的定位参考信号进行检测和测量，以及，在进行测量时，根据上报的测量量的配置信息，进行针对性的测量上报。
可选的，在上述步骤31中，所述网络侧定位设备还可以接收所述终端发送的多个网络侧发送设备的离开角指示信息所对应的RSRP。在上述步骤32 中，网络侧定位设备可以根据网络侧发送设备的离开角指示信息所对应的RSRP，从多个网络侧发送设备中选择出该RSRP大于预设质量门限的网络侧发送设备，并根据所选择出的网络侧发送设备的离开角指示信息，确定所述终端的位置信息。以上处理方式能够保证用于终端定位处理的离开角的可信度，可以减少定位处理的计算量并提高定位结果的准确性。
可选的，为了便于终端计算离开角的取值，在上述步骤31之前，网络侧定位设备(如基站或TRP)还可以将定位参考信号对应的波束方向的角度信息指示给终端，这样终端可以利用上述角度信息，计算得到离开角的取值并上报给网络侧定位设备。
以上分别从终端和网络侧对本公开实施例的测量上报和接收方法进行了说明。下面通过两个终端和网络侧的交互示例，对以上方法作进一步的说明。
示例1：
该示例1以离开角指示信息为离开角所对应的离开角索引为例进行说明。
假设每个收发点(TRP)配置M＝8个定位参考信号(PRS)的资源，每个PRS经过不同的赋形，指向不同的方向。网络侧(可以是定位服务器或者基站)配置终端的上报量为N＝6个TRP的离开角指示信息，且将所述收发点的PRS资源的配置信息指示给终端。
1)基站将每个TRP发送的M＝8个PRS中每个PRS经过赋形后对应的角度信息，上报给定位服务器。
2)终端确定每个TRP发送的M＝8个PRS中的每个PRS的RSRP。并从中确定N＝6个TRP进行离开角指示信息上报。一种确定方式是此N＝6个TRP中，每个TRP发送的M＝8个PRS中的最大RSRP排序在前6。
3)终端针对所述N＝6个TRP中的每个TRP，确定离开角指示信息。以第K个TRP为例，其测得的RSRP分别表示为RSRP1，RSRP2，…，RSRP8。对此8个RSRP进行线性插值、二阶插值或者高阶插值测量，如图4所示，以高阶多项式进行曲线拟合，可以得到该曲线上的最大RSRP(即虚线处的RSRP)，该最大RSRP对应的参考信号的参考索引为3，且索引偏移量为0.5，即离开角索引的索引值为3+0.5＝3.5。同时，也可以通过拟合后的多项式计算得出虚线处的最大RSRP的取值。
4)终端将N＝6个TRP中，每个TRP的离开角指示信息(即离开角所对应的离开角索引)上报给定位服务器。
5)定位服务器根据预先获得的基站上报的所述N＝6个TRP中每个TRP发送的每个PRS对应的角度信息，以及，终端上报的每个TRP的离开角指示信息，确定N＝6个TRP的离开角。一种离开角的确定方式如图5所示，对于第K个TRP，定位服务器已知M＝8个PRS对应的角度信息，表示为。这里可以采用线性拟合的方式，定位服务器可以确定索引为3，且偏移量为0.5处的角度信息，其为此TRP对应的离开角。
6)定位服务器根据N＝6个TRP对应的6个离开角，采用现有的角度定位的算法可以获得终端的位置信息。
示例2：
该示例2以离开角指示信息为离开角的取值为例进行说明。
假设每个收发点(TRP)配置M＝8个PRS的资源，每个PRS经过不同的赋形，指向不同的方向。
1)网络侧(可以是定位服务器或者基站)配置终端的上报量为N＝6个TRP的离开角指示信息，且将所述收发点的PRS资源的配置信息指示给终端。
2)基站将每个TRP发送的M＝8个PRS中每个PRS经过赋形后对应的角度信息，上报给定位服务器。
3)定位服务器将所述每个TRP发送的PRS中的每个PRS对应的角度信息指示给终端。
4)终端确定每个TRP发送的M＝8个PRS中的每个PRS的RSRP，并从中确定N＝6个TRP进行离开角指示信息上报。一种确定方式是此N＝6个TRP中，每个TRP发送的M＝8个PRS中的最大RSRP排序在前6。
5)终端针对所述N＝6个TRP中的每个TRP，确定离开角指示信息。以第K个TRP为例，其测得的RSRP分别表示为RSRP1,RSRP2,…,RSRP8。对此8个RSRP进行线性插值、二阶插值或者高阶插值等处理。仍然以图4中所示的采用高阶多项式进行拟合为例，可以得到最大的RSRP(即虚线处的RSRP)其对应的参考信号的索引为3，且索引偏移量为0.5，即离开角索引的索引值为3.5。同时，也可以通过拟合后的多项式计算得出虚线处的RSRP取 值。
6)终端根据定位服务器指示的每个PRS对应的角度信息，确定N＝6个TRP的离开角。仍然以图5所示的曲线拟合为例，对于第K个TRP，终端已知M＝8个PRS对应的角度信息，表示为。采用线性拟合的方式，定位服务器可以确定索引为3，且偏移量为0.5处的角度信息，其为此TRP对应的离开角。
7)终端将确定出的N＝6个TRP对应的6个离开角作为离开角指示信息上报给定位服务器。
8)定位服务器采用现有的角度定位的算法可以获得终端的位置信息。
