技术领域
本申请实施例涉及通信技术领域，尤其涉及一种测量方法和装置。
背景技术
在5G发展过程中，对于毫米波(频率>6GHz)的应用要求已经确定，毫米波和波束成形技术的结合也使得5G通讯系统拥有高带宽并且支持大量用户同时通讯。目前对于毫米波的接收和测量技术受到了毫米波特性以及5G芯片集成化的影响，只能在空口技术(Over The Air，OTA)环境下进行，在TS38.810中定义了对于毫米波的测量方案，由于受限于对芯片的构造的了解程度不高，毫米波的特性，以及当前的基带测量参考点方案，目前对于基带侧毫米波的RSRP测量值精度的测试需要解决两个问题：一是测试仪器或环境需要知晓对测试机的波束成形增益；二是测试仪器或环境需要排除波束成形增益对误差值的影响。
现有技术中的一种测试方案是在非直接远场测试的情况下，通过在测试机(Device Under Test，DUT)测试时的同一位置放置一个已知增益的参考天线进行对比测试，根据DUT基带上报的参考信号接收功率(Reference Signal Receiving Power，RSRP)与已知增益的参考天线测量的RSRP确定DUT基带测量值的误差。由于该测试方案中带有波束成形增益，因此DUT基带上报的RSRP中同时包含波束成形增益和误差值，而且测试方案中已知增益的参考天线测量的RSRP中也包含波束成形增益，因此，上述波束成形增益会对RSRP测量值的误差造成干扰，导致确定的RSRP测量值的误差并不准确。

在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
为了解决背景技术中，现有的测试方案中的波束成形增益会对测试机基带测量的RSRP的误差造成干扰，导致确定的RSRP测量值的误差不准确的问题，本申请实施例提供了一种测量方法，该方法能够排除波束成形增益对测试结果造成的干扰，以获取更加精确的基带测量值的误差，提升校准的精确度。
结合图1-图3，如图4所示，本申请实施例提供的测量方法，可以包括S401-S404。
S401、测量设备检测测量毫米波信号的参考信号接收功率RSRP测量值。
示例性的，该测量毫米波信号是由图1所示的发射天线发出，该毫米波的频率大于6GHz。
示例性的，该RSRP测量值为带有波束成形增益的RSRP。测量设备检测测量毫米波的RSRP时，一方面由于测量方案中带有波束成形增益，另一方面由于测量设备测 量存在误差，因此该RSRP测量值中包含波束成形增益和基带测量的误差值。
S402、计算测量毫米波信号的信号到达角度AoA。
该信号到达角度AoA为毫米波波束到达的角度。
示例性的，计算测量毫米波信号的信号到达角度AoA可以包括：根据上述测量设备检测的测量毫米波信号的RSRP测量值，计算测量毫米波信号的AoA。例如，可以根据RSRP测量值，采用多信号分类MUSIC算法计算毫米波波束的AoA，具体可参见现有技术，在此不予赘述。本申请实施例对于计算测量毫米波信号的信号到达角度AoA的具体方法并不进行限定，在此仅是示例。
S403、根据AoA查找预配置的数据库，获取该AoA对应的波束成形增益基准值。
其中，该数据库包含至少一个AoA，以及与该至少一个AoA中每个AoA对应的波束成形增益基准值。
该波束成形增益基准值是指发射天线与测量设备射频天线的中心位置的距离为某一距离时，测量毫米波波束信号的AoA对应的波束成形增益的值。
示例性的，一个AoA对应的波束成形增益基准值可以根据在该AoA检测的至少两个RSRP测量值与RSRP真实值获得，该RSRP真实值可以由0dBi全向天线连接的信号分析仪测量的。
上述根据在一个AoA检测的至少两个RSRP测量值与RSRP真实值获得该AoA对应的波束成形增益基准值的具体获取方式可以包括以下步骤S403a-S403c。
S403a、在上述AoA检测至少两个RSRP测量值。
示例性的，该至少两个RSRP测量值是由与上述测量设备型号相同的至少两个测量设备测量的。例如，当该测量设备为基带芯片时，至少两个RSRP测量值是由与该基带芯片型号相同的至少两个基带芯片测量的。可以理解的，本申请实施例通过采用多个基带芯片进行多次测量的目的是为了排除单一基带芯片的影响，以获取较为准确的波束成形增益基准值。
如图5所示，测量设备在A点检测测量毫米波信号的RSRP测量值，记为RSRP A，该A点可以为任意一个位置，该A点确定后，发射天线和测量设备射频天线的中心位置的距离确定。可以理解的，该第一位置满足远场的距离条件。
S403b、在上述AoA检测RSRP真实值。
示例性的，该RSRP真实值可以由0dBi全向天线连接的信号分析仪测量得到。
如图6所示，该0dBi全向天线可以连接信号分析仪测量A点处接收的RSRP真实值，记为RSRP A’，由于0dBi全向天线的特性，其测量的RSRP值中是不包含波束成形增益的。
需要说明的是，该0dBi全向天线的球体中心和上述测量设备射频天线的中心位置对齐。如图7所示，0dBi全向天线的球体中心和测量设备射频天线的中心位置在A点处对齐。
可以理解的，当发射天线和测试机基带射频中心的距离不变时，在毫米波波束的入射角度不同时，该0dBi全向天线测量的RSRP值可以保持不变。
S403c、根据上述至少两个RSRP测量值和RSRP真实值获取上述AoA对应的波束成形增益基准值。
示例性的，可以将上述至少两个RSRP测量值分别和RSRP真实值求差值，获得至少两个波束成形增益的值，再将该至少两个波束成形增益的值求平均值，获得该AoA对应的波束成形增益基准值。例如，测量毫米波信号的信号到达角度为AoA时，对应的波束成形增益基准值为
Figure PCTCN2019097564-appb-000001
其中，n为测量设备的个数，
Figure PCTCN2019097564-appb-000002
为第i个测量设备在A点检测的RSRP测量值。
可以理解的，上述步骤S303a-S303c仅获取了一个信号到达角度AoA对应的波束成形增益的基准值，对于其他信号到达角度对应的波束成形增益基准值可以采用上述同样的方法得到，并将得到的不同信号到达角度所对应的波束成增益的基准值存储在数据库中。
需要说明的是，数据库中存储的信号到达角度AoA的精度本申请实施例并不进行限定，实际应用中，可以根据厂商的不同需求进行设置，可选的，该信号到达角度的精度可以精细一些，例如，该信号到达角度的精度可以为0.5度或者1度。
示例性的，上述根据AoA查找预配置的数据库，获取AoA对应的波束成形增益基准值可以包括：在预配置的数据库中查找是否存在与当前AoA相同的AoA，若存在，将数据库中该AoA对应的波束成形增益确定为当前AoA对应的波束成形增益基准值。本申请实施例对于获取AoA对应的波束成形增益基准值的具体方法并不进行限定，在此仅是示例性说明。
S404、根据RSRP测量值和上述AoA对应的波束成形增益基准值计算测量毫米波信号的RSRP校准值。
其中，该RSRP校准值为排除了波束成形增益后的RSRP。
示例性的，上述根据RSRP测量值和上述AoA对应的波束成形增益基准值计算测量毫米波信号的RSRP校准值可以包括：根据RSRP测量值和波束成形增益基准值求差值，该差值为RSRP校准值。
可以理解的，该RSRP校准值是将包含波束成形增益的RSRP测量值减去该测量毫米波信号的信号到达角度对应的波束成形增益基准值后得到的，因此，该RSRP校准值中不再包含测量方案带来的波束成形增益，能够排除波束成形增益对测试结果的干扰。
本申请实施例提供的测量方法，通过测量设备检测测量毫米波信号的参考信号接收功率RSRP测量值；计算该测量毫米波信号的信号到达角度AoA；根据该AoA查找预配置的数据库，获取该AoA对应的波束成形增益基准值；根据RSRP测量值和该AoA对应的波束成形增益基准值计算测量毫米波信号的RSRP校准值。本申请实施例中的测量方法通过将基带测量的带有波束成形增益的RSRP测量值减去测量毫米波波束信号的信号到达角度对应的波束成形增益的基准值，能够获得不包含波束成形增益的RSRP校准值，从而排除基带波束成形增益对测试方案的影响。
本申请实施例还提供一种测量方法，如图8所示，该方法在步骤S404之后，还包括步骤S405。
S405、根据上述RSRP校准值和RSRP真实值计算测量设备检测的RSRP测量值的误差。
示例性的，上述根据RSRP校准值和RSRP真实值计算测量设备检测的RSRP测 量值的误差可以包括：计算RSRP校准值和RSRP真实值的差值，该差值为测量设备检测的RSRP测量值的误差。
需要说明的是，本申请实施例中的RSRP真实值是由0dBi全向天线连接的测量设备测量的，由于该0dBi全向天线的特性，其测量的RSRP真实值是不包含波束成增益的，与现有技术中采用已知增益的参考天线获取基带测量值的误差相比，本申请实施例采用0dBi全向天线测量RSRP能够排除现有技术中参考天线的波束成形增益对误差带来的影响。
可以理解的，由于上述RSRP校准值不包含波束成形增益，该RSRP校准值已经排除了测试方案中测量设备的波束成形增益，RSRP真实值为0dBi全向天线连接的信号分析仪测量的不包含波束成形增益的RSRP，故将RSRP校准值减去RSRP真实值的差值获得的RSRP测量值的误差，为排除测量设备和参考天线的波束成增益后的误差，该误差值相较于现有技术中直接根据基带测量的RSRP与已知增益的参考天线测量的RSRP确定的误差更为精确。
示例性的，上述获得的RSRP测量值的误差可以用于校准测量设备。例如，当该测量设备为基带芯片时，该基带芯片可以新增一个端口，用于外部设备(例如，校准设备)从外部调用基带芯片获得的排除波束成形增益的RSRP校准值，并将该RSRP校准值与RSRP真实值比较，确定基带芯片测量的RSRP测量值的误差，并根据该测量值的误差对测量设备进行校准。该端口可以只具备调用基带RSRP校准值的功能。
本申请实施例提供的测量方法，通过测量设备检测测量毫米波信号的参考信号接收功率RSRP测量值；计算该测量毫米波信号的信号到达角度AoA；根据该AoA查找预配置的数据库，获取该AoA对应的波束成形增益基准值；根据RSRP测量值和该AoA对应的波束成形增益基准值计算测量毫米波信号的RSRP校准值；根据上述RSRP校准值和RSRP真实值获取测量设备检测的RSRP测量值的误差。本申请实施例中的测量方法通过将基带测量的带有波束成形增益的RSRP测量值减去测量毫米波波束信号的信号到达角度对应的波束成形增益的基准值，能够获得不包含波束成形增益的RSRP校准值，并根据RSRP校准值与RSRP真实值，能够获取更为精确的RSRP测量值误差，该误差排除了基带波束成形增益和参考天线波束成形增益对测试方案的影响，提升了校准的精准度。
