在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。

为便于理解本申请实施例，对本申请中涉及到的术语做简单说明。
一、PRS频率层。
RRS频率层可以是PRS资源集的集合，该PRS资源集具有通过某一个信令配置的公共参数，其中，该信令可以是NR-DL-PRS-Positioning Frequency Layer。
二、模式。
本申请实施例中提及的模式包括模式1和模式2。其中，终端设备测量PRS频率层的处理时间既可以位于该PRS频率层的测量时间窗内，也可以位于该PRS频率层的测量时间窗外，此时对应的模式为模式1；终端设备测量PRS频率层的处理时间位于该PRS频率层的测量时间窗内，此时对应的模式为模式2。
三、测量时间窗。
测量时间窗可以是测量间隔(measurement gap，MG)，也可以是定位参考信号处理窗(positioning reference signal processing window，PPW)，也可以是其它时间窗，本申请对此不予限制。在测量时间窗内，终端设备可以基于不同的模式确定PRS频率层的测量时间，对于终端设备在测量时间窗内确定PRS频率层的测量时间时所采用的具体模式，本申请实施例并不予以限制。例如，在MG内，终端设备可以采用模式1测量PRS频率层的测量时间，也可以采用模式2测量PRS频率层的测量时间；再例如，在PPW内，终端设备可以采用模式1测量PRS频率层的测量时间，也可以采用模式2测量PRS频率层的测量时间。其中，PRS频率层可以是LMF为终端设备配置的，PPW和MG可以是网络设备为终端设备配置的。
在本申请实施例中，当测量时间窗为PPW时，该测量时间窗长度为PPW的长度；当测量时间窗为MG时，该测量时间窗长度为MG长度除前后0.5ms或0.25ms外的长度。
四、{N,T}。
{N,T}为R16标准中引入的终端设备向LMF上报的能力，其中，N为终端设备测量PRS频率层的持续时间能力，T为终端设备测量PRS频率层的处理时间能力，{N,T}与终端设备确定PRS频率层的测量时间时所采用的模式1相关联。T可以位于测量时间长度内，也可以位于测量时间窗长度外。当T位于测量时间窗长度外时，对终端设备接收数据的影响较小，但同时增加了终端设备测量PRS频率层的处理时间。
五、{N2,T2}。
{N2,T2}为R17标准中引入的终端设备向LMF上报的能力，其中，N2为终端设备测量PRS频率层的持续时间能力，T2为终端设备测量PRS频率层的处理时间能力，{N2,T2}与终端设备确定PRS频率层的测量时间时所采用的模式2相关联。T2位于测量时间窗长度内，对终端设备接收数据的影响较大，但同时减小了终端设备测量PRS频率层的处理时间。因此，终端设备基于模式2进行的PRS频率层的测量是一种低时延测量。
现有技术中，当PRS频率层的个数不止一个时，终端设备如何基于模式2测量至少一个PRS频率层的总测量时间，目前并未有相关方案予以说明。
鉴于上述技术问题，本申请提供了一种通信方法，可以使得终端设备确定基于模式2测量至少一个PRS频率层的总测量时间。通过该方法，能够减少终端设备采用模式2测量至少一个PRS频率层的总测量时间。
下面将结合附图详细说明本申请提供的各个实施例。
图1示出了本申请实施例提供的一种通信方法100的示意图。如图1所示，方法100可以包括如下步骤。
110，终端设备确定采用模式2测量Q个PRS频率层中的每个PRS频率层所用的时间。
其中，Q为正整数。
可选地，终端设备测量Q个PRS频率层中的第二PRS频率层所用的时间可以根据第一时间和/或第二时间确定。
其中，第二PRS频率层为Q个PRS频率层中的其中之一。
其中，第一时间为测量第二PRS频率层所用的采样时间。
其中，第二时间为测量第二PRS频率层的最后一个样点的测量时间。
示例性地，终端设备采用模式2测量第二PRS频率层所用的时间满足公式(1)：
其中，
其中，Tmeas,i为终端设备测量第二PRS频率层所用的时间，Lavailable_PRS,i为第一时间，Tlast,i为第二时间，M为其它因素导致第二PRS频率层的测量时间的放大的因子，例如，在毫米波频率测量中，终端设备采用多个接收波束测量时的波束扫描因子等，本申请对其它因素导致第二测量时间放大的因子不做限定。为每个时隙内终端设备需要测量的PRS资源数的最大值，N'为每个时隙内终端设备可以测量的PRS资源数的能力，N2为终端设备测量第二PRS频率层的持续时间能力，Nsample为测量第二PRS频率层的样点数，Teffect,i为第二PRS频率层的有效测量周期，Twindow,i为第二PRS频率层的第二测量时间窗的周期，T2为终端设备测量第二PRS频率层的处理时间能力，Tavailable_PRS,i为第二PRS频率层的可获得周期，Tavailable_PRS,i可以是TPRS,i与Twindow,i的最小公倍数，TPRS,i为第二PRS频率层的周期。
应理解，终端设备可以根据公式(1)和公式(2)确定采用模式2测量第二PRS频率层所用的时间，也可以根据公式(1)和公式(2)确定采用模式2测量除第二PRS频率层外的其它PRS频率层所用的时间。
120，终端设备根据Q个PRS频率层中的每个PRS频率层所用时间的最大值，确定第二测量时间。
示例性地，终端设备确定第二测量时间满足公式(3)：
Tmeas2＝max(Tmeas,i++Tuncertainty,i)      (3)
其中，Tmeas2为第二测量时间，Tuncertainty,i为大于或等于零的余量，例如，Tuncertainty,i为从第二测量时间的起始时刻(即Q个PRS频率层对应的所有测量时间窗中的第一个测量时间窗)到第i个PRS频率层的第一个测量时间窗之间的距离，Tmeas,i为终端设备测量Q个PRS频率层中的第i个PRS频率层所用的时间。
其中，第i个PRS频率层为Q个PRS频率层中的其中之一，即第i个PRS频率层可以为第二PRS频率层。
基于上述技术方案，终端设备可以确定采用模式2测量Q个PRS频率层中的每个PRS频率层所用 的时间，并根据Q个PRS频率层中的每个PRS频率层所用时间的最大值，确定第二测量时间。通过该方法，可以减少终端设备采用模式2测量至少一个PRS频率层的总测量时间。
基于步骤110，终端设备确定第一时间可以有以下几种可能的方式。
一种可能的方式，第一时间为PRS资源的持续时间，该PRS资源的持续时间位于第一窗口内，该第一窗口的长度为第二PRS频率层的第二测量时间窗长度与T2之间的差，该第一窗口的起始位置为第二测量时间窗长度的起点。
其中，T2为终端设备测量第二PRS频率层的处理时间能力长度。
如图2所示，第一窗口的长度为第二PRS频率层的第二测量时间窗长度与T2之间的差，PRS资源的持续时间位于第一窗口内，可以理解为，PRS资源的持续时间可以是第一窗口的长度中的全部，也可以是第一窗口的长度中的部分。
应理解，第二测量时间窗可以是周期性出现的，一个周期内的第二测量时间窗可以记为第二测量时间窗的一个实例，多个周期内的第二测量时间窗可以记为第二测量时间窗的多个实例。如果一个Tavailable_PRS,i或者TPRS,i内有第二测量时间窗的多个实例，则第一时间为Tavailable_PRS,i或者TPRS,i内PRS资源的持续时间，该PRS资源的持续时间位于该第二测量时间窗的多个实例的第一窗口内。也就是说，第一时间是PRS资源在一个Tavailable_PRS,i或者TPRS,i内的持续时间，在计算第一时间时，仅考虑在第一窗口内的PRS资源，例如，在计算第一时间时，仅考虑第二测量时间窗内前Hms内的PRS资源，其中，H为第二测量时间窗长度与T2之间的差。
另一种可能的方式，第一时间为PRS资源的持续时间与N2之间的最小值，该PRS资源的持续时间位于第一窗口内，该第一窗口的长度为第二PRS频率层的第二测量时间窗长度与T2之间的差，该第一窗口的起始位置为第二测量时间窗长度的起点。
其中，第一时间为PRS资源的持续时间与N2之间的最小值，可以理解为，第一时间为PRS资源的持续时间，PRS资源的持续时间小于或等于N2。
其中，T2为终端设备测量第二PRS频率层的处理时间能力，N2为终端设备测量第二PRS频率层的持续时间能力。
如图2所示，第一窗口的长度为第二PRS频率层的第二测量时间窗长度与T2之间的差，PRS资源的持续时间位于第一窗口内，可以理解为，PRS资源的持续时间可以是第一窗口的长度中的全部，也可以是第一窗口的长度中的部分。此时，第一时间为PRS资源的持续时间与N2之间的最小值。例如，当PRS资源的持续时间大于N2时，第一时间为N2；再例如，当PRS资源的持续时间小于N2时，第一时间为PRS资源的持续时间；再例如，当PRS资源的持续时间等于N2时，第一时间为可以是N2，也可以是PRS资源的持续时间。
另一种可能的方式，如图3所示，假设将第二测量时间窗长度记为L，则第二测量时间窗长度L可以分为个时间段，其中，第m个时间段的长度为N2与T2的和。在第m个时间段内，第一子时间为第m个时间段内PRS资源的持续时间与N2之间的最小值，在第二测量时间窗内，第一时间为M个第一子时间的和。
其中，T2为终端设备测量第二PRS频率层的处理时间能力，N2为终端设备测量第二PRS频率层的持续时间能力。
基于上述技术方案，通过规定采用模式2测量第二PRS频率层所用的采样时间，可以在第二测量时间窗内预留足够的测量第二PRS频率层的处理时间，确保终端设备可以在第二测量时间窗内完成处理，进而降低测量时延。
基于步骤110，终端设备确定第二时间可以有以下几种可能的方式。
一种可能的方式，当第二PRS频率层的所有PRS资源在第二PRS频率层的第二测量时间窗内时，第二时间为第二PRS频率层的第二测量时间窗长度。
应理解，在第二PRS频率层所在的带宽范围内，可以有一个PRS资源，也可以有多个PRS资源，本申请实施例对此不予限制。
示例性地，假设在第二PRS频率层所在的带宽范围内有6个PRS资源，当该6个PRS资源均在第二测量时间窗内时，第二时间为第二测量时间窗长度。
另一种可能的方式，当第二PRS频率层存在PRS资源不在第二PRS频率层的第二测量时间窗内 时，第二时间为第二PRS频率层的可获得周期。
示例性地，假设在第二PRS频率层所在的带宽范围内有6个PRS资源，当有2个PRS资源不在第二测量时间窗内时，第二时间为第二PRS频率层的可获得周期。
可选地，终端设备可以确定采用模式1测量P个PRS频率层中的每个PRS频率层所用的时间。
关于终端设备采用模式1测量P个PRS频率层中的每个PRS频率层所用时间的计算公式，可参考公式(1)、公式(2)以及现有方案，在此不再进行赘述。
可选地，终端设备根据P个PRS频率层中的每个PRS频率层所用时间的和，确定第一测量时间，其中，P为正整数。
示例性地，终端设备确定第一测量时间满足公式(4)：
Tmeas1＝sum(Tmeas,i)+(P-1)*max(Teffect,i)      (4)
其中，Tmeas1为第一测量时间，Tmeas,i为终端设备测量P个PRS频率层中的第i个PRS频率层所用的时间，Teffect,i为P个PRS频率层中的第一PRS频率层的有效测量周期。
其中，第一PRS频率层为P个PRS频率层中的其中之一，第i个PRS频率层为P个PRS频率层中的其中之一，即第i个PRS频率层可以为第一PRS频率层。
可选地，终端设备根据第一测量时间和第二测量时间，确定第三测量时间。
其中，第三测量时间为测量P+Q个PRS频率层所用的时间。
示例性地，终端设备根据第一测量时间、第二测量时间和第一余量，确定第三测量时间，该第三测量时间为第一测量时间、第二测量时间和第一余量的和。
其中，第一余量可以是不同频率层之间进行转换时所用的时间，第一余量为大于或等于0的数。例如，第一余量可以是第一频率层转换为第二频率层时所用的时间；再例如，第一余量可以是第二频率层转换为第一频率层时所用的时间；再例如，第一余量可以是max(Teffect,i)。
现有技术中，PRS频率层的测量模式可以是模式1，也可以是模式2。然而，终端设备如何确定PRS频率层的测量模式为模式1还是模式2，目前并未有相关方案予以说明。例如，终端设备如何确定方法100中提及的第一PRS频率层的测量模式为模式1，以及，终端设备如何确定第二PRS频率层的测量模式为模式2，现有方案中并未有相关说明。
鉴于上述技术问题，本申请提供了一种通信方法。通过该方法，本申请可以使得终端设备确定PRS频率层的测量模式为模式1还是模式2，从而能够明确终端设备的测量行为。
图4示出了本申请实施例提供的又一种通信方法400的示意图。如图4所示，方法400可以包括如下步骤。

示例性地，基于方法100，终端设备可以根据向LMF上报的第一能力，确定第一PRS频率层的测量模式为模式1。
示例性地，终端设备可以根据向LMF上报的第二能力，确定第二PRS频率层的测量模式为模式2。
基于上述技术方案，终端设备可以根据向LMF上报的能力，确定PRS频率层的测量模式为模式1 还是模式2，从而能够明确终端设备的测量行为。
基于步骤420，终端设备根据向LMF上报的能力，确定PRS频率层的测量模式，可以有以下几种方式。
方式#A：当终端设备向LMF上报的能力为{N,T}时，终端设备确定PRS频率层的测量模式为模式1；或者，当终端设备向LMF上报的能力为{N2,T2}时，终端设备确定PRS频率层的测量模式为模式2。

示例性地，基于方法100，当终端设备向LMF上报的第一能力为{N,T}和{N2,T2}，时，终端设备可以接收来自LMF的第一指示信息，该第一指示信息指示第一PRS频率层的测量模式为模式1。
示例性地，基于方法100，当终端设备向LMF上报的第二能力为{N,T}和{N2,T2}时，终端设备可以接收来自LMF的第一指示信息，该第一指示信息指示第二PRS频率层的测量模式为模式2。
方式#C：当终端设备向LMF上报的能力为{N,T}和{N2,T2}时，终端设备接收来自网络设备的第二指示信息，该第二指示信息用于指示PRS频率层的测量时间窗长度。终端设备可以根据第二指示信息，确定PRS频率层的测量模式为模式1或模式2。
举例来说，当PRS频率层的测量时间窗长度大于或等于第一阈值时，终端设备确定PRS频率层的测量模式为模式2；或者，当PRS频率层的测量时间窗长度小于该第一阈值时，终端设备确定PRS频率层的测量模式为模式1。
其中，该第一阈值可以是T2+X1，X1为大于等于0的数，该X1可以是协议预定义的，例如，协议预定义X1可以是一个时隙的长度；X1也可以是N2，也可以是其它值，本申请实施例对此不予限制。
示例性地，基于方法100，当终端设备向LMF上报的第一能力为{N,T}和{N2,T2}时，终端设备可以接收来自网络设备的第二指示信息，该第二指示信息用于指示第一PRS频率层的第一测量时间窗长度。终端设备根据第一测量时间窗长度小于第一阈值，确定该第一PRS频率层的测量模式为模式1。
示例性地，基于方法100，当终端设备向LMF上报的第二能力为{N,T}和{N2,T2}时，终端设备可以接收来自网络设备的第二指示信息，该第二指示信息用于指示第二PRS频率层的第二测量时间窗长度。终端设备根据第二测量时间窗长度大于或等于第一阈值，确定第二PRS频率层的测量模式为模式2。
应理解，基于方法100，当终端设备向LMF同时上报第一能力和第二能力时，终端设备可以根据方式#A～方式#C中的其中一种或者不同组合形式，确定第一PRS频率层的测量模式为模式1，以及，确定第二PRS频率层的测量模式为模式2。
例如，当终端设备向LMF上报的第一能力为{N,T}，以及，终端设备向LMF上报的第二能力为{N2,T2}时，终端设备可以根据方式#A，确定第一PRS频率层的测量模式为模式1，以及，终端设备可以根据方式#A，确定第二PRS频率层的测量模式为模式2。
再例如，当终端设备向LMF上报的第一能力为{N,T}，以及，终端设备向LMF上报的第二能力为{N,T}和{N2,T2}时，终端设备可以根据方式#A，确定第一PRS频率层的测量模式为模式1，以及，终端设备可以根据方式#B或方式#C，确定第二PRS频率层的测量模式为模式2。

现有技术中，网络设备可以为终端设备配置PRS频率层的测量时间窗长度，然而，当网络设备为终端设备配置的PRS频率层的测量时间窗长度较小，例如，网络设备为终端设备配置的PRS频率层的测量时间窗长度小于第一阈值时，终端设备可能无法将PRS频率层的测量模式确定为模式2。
因此，由于网络设备为终端设备配置的PRS频率层的测量时间窗长度不满足低时延测量的条件，可能会导致终端设备无法进行低时延测量。
示例性地，基于方法400，在方式#A中，即使终端设备向LMF上报的能力为{N2,T2}，当网络设备为终端设备配置的PRS频率层的测量时间窗长度较小时，终端设备可能也无法正确的使用模式2进行测量。
示例性地，基于方法400，在方式#B中，当网络设备为终端设备配置的PRS频率层的测量时间窗长度较小时，即使LMF向终端设备发送的第一指示信息指示PRS频率层的测量模式为模式2，终端设备可能也无法正确的使用模式2进行测量。也就是说，当终端设备根据第一指示信息确定PRS频率层的测量模式为模式2时，终端设备正确执行测量的条件是网络设备为终端设备配置的测量时间窗的长度大于或等于第一阈值。
鉴于上述技术问题，本申请提供了一种通信方法。通过该方法，本申请可以使得网络设备能够根据低时延相关的信息为终端设备配置PRS频率层的测量时间窗长度，进而可以根据LMF或者终端设备的需求使能终端设备使用模式2进行测量。

其中，网络设备获得PRS资源的持续时间的方式可以参考现有方案，例如，LMF可以通过NRPPa向网络设备发送测量预配置请求(MEASUREMENT PRECONFIGURATION REQUIRED)消息，该消息中包括PRS资源的持续时间的相关信息，从而可以使得网络设备可以获得PRS资源的持续时间。可选地，第一建议值可以包含在该NRPPa消息中。

基于上述技术方案，网络设备可以根据第三指示信息，确定PRS频率层的测量时间窗长度，使得网络设备能够根据低时延相关的信息为终端设备配置PRS频率层的测量时间窗长度，进而可以根据LMF或者终端设备的需求使能终端设备使用模式2进行测量。

示例性地，基于方法100，网络设备向终端设备发送第二指示信息，该第二指示信息用于指示第一PRS频率层的第一测量时间窗长度，以及，该第二指示信息用于指示第二PRS频率层的第二测量时间窗长度。其中，该第二测量时间窗长度可以是网络设备根据第三指示信息确定的。
关于终端设备根据第二指示信息，确定PRS频率层的测量模式为模式1或模式2的说明，可以参考方法400中的描述，在此不再进行赘述。
现有技术中，PRS频率层的测量时间窗可以是PPW，也可以是MG。然而，终端设备如何确定PRS频率层的测量时间窗为PPW还是MG，目前并未有相关方案予以说明。例如，终端设备如何确定方法100中提及的第一PRS频率层的第一测量时间窗为PPW还是MG，以及，终端设备如何确定第二PRS频率层的第二测量时间窗为PPW还是MG，现有方案中并未有相关说明。
鉴于上述技术问题，本申请提供了一种通信方法。通过该方法，本申请可以使得终端设备确定PRS频率层的测量时间窗为PPW还是MG，从而能够明确终端设备的测量行为，并确保终端设备、网络设备和LMF理解一致。
图6示出了本申请实施例提供的又一种通信方法600的示意图。如图6所示，方法600可以包括如下步骤。
610，终端设备接收来自网络设备的第四指示信息，该第四指示信息用于指示PPW是否处于激活状态，该PPW与PRS频率层相关联。
其中，PRS频率层可以是LMF为终端设备配置的，PPW和MG可以是网络设备为终端设备配置的。
示例性地，基于方法100，终端设备接收来自网络设备的第四指示信息，该第四指示信息用于指示第一PPW是否处于激活状态，该第一PPW与P个PRS频率层中的第一PRS频率层相关联。
其中，第一PPW与第一PRS频率层相关联，可以理解为，第一PPW配置在第一服务小区的第一部分带宽(bandwidth part，BWP)中，第一BWP包含第一PRS频率层，且第一BWP与第一PRS频率层的子载波间隔相同，则第一PPW与第一PRS频率层相关联。

示例性地，基于方法100，终端设备根据第四指示信息，确定第一PRS频率层的第一测量时间窗。
示例性地，基于方法100，终端设备根据第四指示信息，确定第二PRS频率层的第二测量时间窗。
基于上述技术方案，终端设备可以根据第四指示信息，确定PRS频率层的测量时间窗，从而能够明确终端设备的测量行为，并确保终端设备、网络设备和LMF理解一致。
基于步骤620，终端设备根据第四指示信息，确定PRS频率层的测量时间窗，可以有以下两种可能的方式。
一种可能的方式，当第四指示信息指示PPW处于激活状态时，终端设备确定PRS频率层的测量时间窗为PPW。
示例性地，当第四指示信息指示第一PPW处于激活状态时，终端设备确定第一PRS频率层的第一测量时间窗为第一PPW。
示例性地，当第四指示信息指示第二PPW处于激活状态时，终端设备确定第二PRS频率层的第二测量时间窗为第二PPW。
另一种可能的方式，当第四指示信息指示PPW处于未激活状态时，终端设备确定PRS频率层的测量时间窗为MG。
示例性地，当第四指示信息指示第一PPW处于未激活状态时，终端设备确定第一PRS频率层的第一测量时间窗为第一MG。
示例性地，当第四指示信息指示第二PPW处于未激活状态时，终端设备确定第二PRS频率层的第二测量时间窗为第二MG。
应理解，当PPW与MG相关联的PRS频率层不同时，PPW与MG可以同时存在。例如，第一PRS频率层的第一测量时间窗为第一PPW，与第二PRS频率层的第二测量时间窗为第二MG可以同时存在。
可选地，当PRS频率层没有相关联的PPW时，终端设备确定PRS频率层的测量时间窗为MG。
可选地，当PPW和MG在时域上相冲突时，终端设备在冲突的PPW的一个实例上不测量PRS频率层。
其中，该PPW与该MG相关联的PRS频率层不同。
示例性地，网络设备配置的该PPW的周期为80ms，时域的起始位置为0，网络设备配置的该MG的周期为160ms，时域的起始位置为0，则每经过160ms会有1个PPW与MG存在时域上的冲突，此时终端设备在冲突的PPW的一个实例上不测量PRS频率层。
示例性地，基于方法100，假设Q个PRS频率层中的每个PRS频率层的测量时间窗为PPW，P个PRS频率层中的每个PRS频率层的测量时间窗为MG，则终端设备可以确定在PPW内采用模式2测量Q个PRS频率层中的每个PRS频率层所用的时间，并根据Q个PRS频率层中的每个PRS频率层所用时间的最大值，确定第二测量时间，以及，终端设备还可以确定在MG内采用模式1测量P个PRS频率层中的每个PRS频率层所用的时间，并根据P个PRS频率层中的每个PRS频率层所用时间的和，确定第一测量时间。基于此，终端设备可以根据第一测量时间和第二测量时间，确定第三测量时间。
应理解，Q个PRS频率层中的每个PRS频率层的测量时间窗为PPW，即，该Q个PRS频率层的PPW的个数有Q个，且该Q个PPW中可以存在相同的PPW，也可以是该Q个PPW互不相同；P个PRS频率层中的每个PRS频率层的测量时间窗为MG，即，该P个PRS频率层的MG的个数有P个，且该P个MG可以存在相同的MG，也可以是该P个MG互不相同。
示例性地，基于方法100，假设Q个PRS频率层中的每个PRS频率层的测量时间窗为PPW2，P个PRS频率层中的每个PRS频率层的测量时间窗为PPW1，则终端设备可以确定在PPW2内采用模式2测量Q个PRS频率层中的每个PRS频率层所用的时间，并根据Q个PRS频率层中的每个PRS频率层所用时间的最大值，确定第二测量时间，以及，终端设备还可以确定在PPW1内采用模式1测量P个PRS频率层中的每个PRS频率层所用的时间，并根据P个PRS频率层中的每个PRS频率层所用时间的和，确定第一测量时间。基于此，终端设备可以根据第一测量时间和第二测量时间，确定第三测量时间。
应理解，Q个PRS频率层中的每个PRS频率层的测量时间窗为PPW2，即，该Q个PRS频率层的PPW2的个数有Q个，且该Q个PPW2中可以存在相同的PPW，也可以是该Q个PPW2互不相同；P个PRS频率层中的每个PRS频率层的测量时间窗为PPW1，即，该P个PRS频率层的PPW1的个数有P个，且该P个PPW1中可以存在相同的PPW，也可以是该P个PPW1互不相同。
示例性地，假设M个PRS频率层中的每个PRS频率层的测量时间窗为PPW，N个PRS频率层中的每个PRS频率层的测量时间窗为MG，则终端设备可以确定在PPW内采用模式1测量M个PRS频率层中的每个PRS频率层所用的时间，并根据M个PRS频率层中的每个PRS频率层所用时间的和，确定测量时间1，以及，终端设备还可以确定在MG内采用模式1测量N个PRS频率层中的每个PRS频率层所用的时间，并根据N个PRS频率层中的每个PRS频率层所用时间的和，确定测量时间2。基于此，终端设备可以根据测量时间1和测量时间2的和，确定测量时间3。
应理解，M个PRS频率层中的每个PRS频率层的测量时间窗为PPW，即，该M个PRS频率层的PPW的个数有M个，且该M个PPW中可以存在相同的PPW，也可以是该M个PPW互不相同；N个PRS频率层中的每个PRS频率层的测量时间窗为MG，即，该N个PRS频率层的MG的个数有N个，且该N个MG中可以存在相同的MG，也可以是N个MG互不相同。
