可选地，在本公开实施例中PRS可以表示所有可用于测量到达时间(Time of Arrival，TOA)的参考信号，例如：PRS可以包括用于传统下行到达时间差(Downlink Time Difference Of Arrival，DL-TDOA)定位的PRS，信道状态信息参考信号(Channel state indication reference signal，CSI-RS)等。
以下针对申请中的技术术语的含义进行说明：
下行PRS资源定义为一个用于下行PRS传输的资源单元(Resource Element，RE)集合。在时域上，该RE集合可以包含一个时隙中1个或多个连续符号。
下行PRS资源集是同一个TRP的一组下行PRS资源的集合。下行PRS资源集中的每个下行PRS资源关联到单个TRP发送的单个空间发送滤波器(即发送波束)。一个TRP可配置一个或2个下行PRS资源集。UE是否支持2个下行PRS资源集的配置取决于UE能力。
下行PRS定位频率层是一个或跨多个TRP的，具有相同SCS、CP类型、Point A、PRS带宽和起始PRB位置的下行PRS资源集的集合。
可选地，针对周期性下行PRS，下行PRS资源周期的取值范围为：{4,8,16,32,64,5,10,20,40,80,160,320,640,1280,2560,5120,10240}2 μ时隙，其中，μ＝{0,1,2,3}分别对应于PRS子载波间隔{15,30,60,120}kHz。
其中，NR PRS配置和带宽部分(BandWidth Part，BWP)配置相互独立，即NR PRS的配置不受BWP配置带宽的约束。同一个下行PRS定位频率层的所有下行PRS资源集具有相同的下行PRS带宽和起始PRB值。下行PRS起始PRB参数的颗粒度为1，最小值为0，最大值为2176。下行PRS带宽配置的颗粒度是4PRB，最大值取决于UE向网络上报的UE处理下行PRS带宽能力，且下行PRS带宽不小于24PRB。
其中，当UE没有配置测量Gap时，UE不期望进行PRS接收和测量的处理。当配置了测量Gap时，UE可在配置的测量Gap内，测量已激活下行BWP内、与激活下行BWP子载波间隔相同或不相同的PRS资源，或测量已激活下行BWP之外(包括同频或异频)的下行PRS资源。UE根据需要，通过RRC信令申请测量间隙Gap。在测量间隙内，UE不处理其他下行物理信道和信号。
其中，针对周期性下行PRS，定义了两种类型的测量Gap：基于UE(Per-UE)的测量Gap和基于频率范围(Freqeuncy Range，FR)(Per-FR)的测量Gap，并且给出了24种测量Gap图样的测量Gap长度(Measurement Gap Length，MGL)和测量Gap重复周期(Measurement Gap Repetition Period，MGRP)， 如下表1所示。其中，所有的测量Gap都是周期性配置的。

具体地，本公开的实施例提供了一种测量配置方法，解决了目前针对非周期下行PRS或半持续下行PRS在测量Gap内的处理方法，还没有解决方案的问题。
如图1所示，本公开的实施例提供了一种测量配置方法，具体包括以下步骤：
步骤11：为终端配置非周期下行PRS或半持续下行PRS的目标测量间隔Gap。
其中，所述目标测量Gap为非周期测量Gap或者半持续测量Gap。
可选地，针对非周期下行PRS的目标测量Gap为非周期测量Gap，针对 半持续测量Gap的目标测量Gap为半持续测量Gap。
可选地，对非周期下行PRS或半持续下行PRS的测量Gap可以是专用于定位的测量Gap，即与用于其它用途的当前的测量Gap占用不同的时间资源；也可以是和当前的测量Gap复用相同的时间资源。
本公开实施例中，通过网络设备为终端配置非周期下行PRS或半持续下行PRS的目标测量间隔Gap，解决了目前针对非周期下行PRS或半持续下行PRS在测量Gap内的处理方法，还没有解决方案的问题；并且能够避免针对对非周期下行PRS或半持续下行PRS在周期测量Gap内进行处理时，可能存在无法处理，或无法满足较低定位时延的指标的问题，也即能够降低定时时延。
可选地，网络设备可以根据目标消息信息，为所述终端配置所述目标测量Gap；其中，所述目标消息信息为终端上报的终端定位测量能力信息或终端已上报数据的历史信息。也即网络设备可以选择/自主选择配置非周期下行PRS或半持续下行PRS的目标测量Gap。
例如：网络设备可以选择显示和/或隐式的方法配置非周期下行PRS或半持续下行PRS的目标测量Gap，如网络设备根据终端上报的终端定位测量能力信息，选择显示和/或隐式的方法配置非周期下行PRS或半持续下行PRS的目标测量Gap。
可选地，所述目标测量Gap的时间单位与所述终端上报的终端定位测量能力信息相关；所述目标测量Gap的时间单位为：子帧、时隙或正交频分复用(Orthogonal frequency division multiplex，OFDM)符号。例如：根据终端定位测量能力等级与目标测量Gap的时间单位的对应关系，确定终端上报的终端定位测量能力等级对应的目标测量Gap的时间单位。
可选地，所述终端定位测量能力信息包括以下至少一项：
在相同的子帧或时隙内，终端能否同时进行定位测量和下行处理；
在下行激活带宽部分，终端能否同时进行定位测量和下行处理；
在相同频段的不同带宽部分，终端能否同时进行定位测量和下行处理；
在不同频段内，终端能否同时进行定位测量和下行处理；
其中，所述下行处理包括下行信道处理或除了下行PRS之外的下行信号 的处理。
可选地，终端定位测量能力等级与目标测量Gap的时间单位的对应关系也可以参见隐式配置目标测量Gap的实施例中，终端定位测量能力信息与配置参数的对应关系。
又例如：网络设备可以自主选择显示和/或隐式的方法配置非周期下行PRS或半持续下行PRS的目标测量Gap，如网络设备根据终端已上报数据的历史信息，自主选择显示和/或隐式的方法配置非周期下行PRS或半持续下行PRS的目标测量Gap。
可选地，所述步骤11可以具体包括：发送所述目标测量间隔Gap的配置参数至所述终端；和/或，为所述终端配置非周期下行PRS或半持续下行PRS的目标持续时间；其中，所述目标持续时间为所述非周期下行PRS或半持续下行PRS所在的子帧、时隙或OFDM符号，通过配置所述目标持续时间的方式来配置所述目标测量Gap。
例如：网络设备可以通过显式的方式配置非周期下行PRS或半持续下行PRS的目标测量Gap，并发送所述目标测量间隔Gap的配置参数至所述终端，以通知UE非周期下行PRS或半持续下行PRS的目标测量Gap。
可选地，所述发送所述目标测量Gap的配置参数至所述终端的步骤，可以具体包括：通过第一信令发送所述目标测量Gap的配置参数至所述终端。
其中，所述第一信令可以为：长期演进定位协议(LTE Positioning Protocol，LPP)信令、无线资源控制(Radio Resource Control，RRC)信令、媒体接入控制的控制单元(Medium Access Control Control Element，MAC-CE)信令或者下行控制信息(Downlink Control Information，DCI)信令。
可选地，在所述目标测量Gap为非周期下行PRS的非周期测量Gap的情况下，所述发送所述目标测量Gap的配置参数至所述终端，包括：
将所有下行小区的非周期下行定位参考信号PRS资源集的起始时刻的最小值，确定为所述非周期测量Gap的第一起始时刻；
将所有下行小区的非周期下行PRS资源集的结束时刻的最大值，确定为所述非周期测量Gap的第一结束时刻；
发送所述非周期测量Gap的第一配置参数至所述终端；
其中，所述第一配置参数包括：所述第一起始时刻、所述第一结束时刻和第一持续时间中的任意两个，所述第一持续时间是从所述第一起始时刻到所述第一结束时刻的持续时间长度，如第一持续时间L1＝T2-T1；其中，T2为第一起始时刻，T1为第一起始时刻。
例如：网络设备一共配置了N个发送和接收点(Transmit and Receive Point，TRP)，每个TRP可以包括至少一个下行PRS资源集；T1表示非周期测量Gap起始时刻，T2表示非周期测量Gap结束时刻，L1表示非周期测量Gap的持续时间。
其中，网络设备可以通过显式信令通知T1、T2和L1中的任意两个值。可选地，显式信令可以是LPP信令、RRC信令、MAC-CE信令或者DCI信令。
其中，T1＝min{T1(TRP#1),T1(TRP#2),…,T1(TRP#N)}；即T1为所有下行小区的非周期下行PRS资源集的起始时刻的最小值。
T2＝max{T2(TRP#1),T2(TRP#2),…,T2(TRP#N)}；即T2为所有下行小区的非周期下行PRS资源集的结束时刻的最大值。
L＝T2-T1。
其中，T1、T2和L的时间单位可以是子帧或者时隙或者OFDM符号。子帧的优点在于绝对时间，由于PRS周期的单位是子帧，可以保证一致；时隙的优点在于PRS资源和PRS资源集的时域映射是以时隙为基本单位；OFDM符号的优点在于颗粒度较小，占用的时频资源开销较小。
如图2所示，采用时隙为单位，一共配置了N个TRP，每个TRP包含1个下行PRS资源集，每个下行PRS资源集包含4个下行PRS资源，每个下行PRS资源包含6个OFDM符号，所有TRP的下行PRS资源集之间采用连续的时隙分配，即时分复用(Time division multiplexing，TDM)方式。因此，每个下行PRS资源集占用2个连续的时隙。N个TRP一共占用2N个连续的下行时隙，即L1＝2N。
可选地，所述目标测量Gap为半持续下行PRS的半持续测量Gap的情况下，所述发送所述目标测量Gap的配置参数至所述终端的步骤，可以包括：
在一个半持续下行PRS周期内，将所有下行小区的半持续下行PRS资源 集的起始时刻的最小值，确定为所述半持续测量Gap的第二起始时刻；
在所述半持续下行PRS周期内，将所有下行小区的半持续下行PRS资源集的结束时刻的最大值，确定为所述半持续测量Gap的第二结束时刻；
发送所述半持续测量Gap的第二配置参数至所述终端；
其中，所述第二配置参数包括：所述半持续测量Gap的重复周期和一个半持续测量Gap的配置参数；所述一个半持续测量Gap的配置参数包括：所述第二起始时刻、所述第二结束时刻和第二持续时间中的任意两个，所述第二持续时间是从所述第二起始时刻到所述第二结束时刻的持续时间长度，如第二持续时间L2＝T2-T1；其中，T1为第二起始时刻，T2为第一起始时刻。
其中，所述半持续下行PRS的半持续测量Gap的重复周期等于或者大于半持续下行PRS的重复周期。
可选地，在所述目标测量Gap为半持续下行PRS的半持续测量Gap的情况下，所述方法还包括：
发送第二信令至所述终端；其中，所述第二信令用于激活所述半持续测量Gap；或者，发送第三信令至所述终端；其中，所述第三信令用于指示激活半持续下行PRS以及激活所述半持续测量Gap。
可选地，针对半持续测量Gap，当半持续下行PRS去激活时，自动失效。
例如：一共配置了N个TRP，不同TRP的下行PRS资源集之间采用TDM复用方式，T1表示半持续测量Gap起始时刻，T2表示半持续测量Gap的结束时刻，L2表示半持续测量Gap在一个周期内的持续时间，P表示半持续测量Gap的重复周期。
其中，网络设备可以通过显式信令通知T1、T2和L2之间的任意两个，以及P。可选地，显式信令可以是LPP信令、RRC信令、MAC-CE信令或者DCI信令。
其中，T1＝min{T1(TRP#1),T1(TRP#2),…,T1(TRP#N)}；即T1是在一个半持续下行PRS周期内，所有下行小区的半持续下行PRS资源集的起始时刻的最小值。
T2＝max{T2(TRP#1),T2(TRP#2),…,T2(TRP#N)}；即T2是在所述半持续下行PRS周期内，所有下行小区的半持续下行PRS资源集的结束时刻的最大 值。
L2＝T2-T1；T3＝T1+P；T4＝T2+P。
其中，T3为下一个重复周期的半持续测量Gap的起始时刻，T4为下一个重复周期的半持续测量Gap的结束时刻。T1、T2、T3、T4、L2和P的时间单位可以是子帧或者时隙或者OFDM符号(具体可以根据终端定位测量能力信息确定)。
如图3所示，采用时隙为单位，一共配置了N个TRP，每个TRP包含1个下行PRS资源集，每个下行PRS资源集包含4个下行PRS资源，每个下行PRS资源包含6个OFDM符号，所有TRP的下行PRS资源集之间采用连续的时隙分配，即TDM复用方式。因此，每个下行PRS资源集占用2个连续的时隙。N个TRP一共占用2N个连续的下行时隙，即L＝2N。半持续下行PRS重复两次，P＝8N。
又例如：网络设备可以通过隐式配置的方式，为终端配置非周期下行PRS或半持续下行PRS的目标测量Gap。即网络设备不通过显式信令配置UE的定位测量Gap，而是在配置非周期下行PRS或者半持续下行PRS所在的时域资源(或者称为目标持续时间，如非周期下行PRS或者半持续下行PRS所在的子帧、时隙或者OFDM符号)，终端通过协议预定义方式，默认进行下行定位信号接收和测量处理。
可选地，UE可以根据其向网络设备上报的终端定位测量能力信息，选择在隐式的配置方式确定的定位测量Gap内，选择下面两种方式之一进行处理：
方式1：UE只能进行定位测量操作，不能接收处理下行信道和第一下行信号。
方式2：UE既可以进行定位测量操作，也可以接收处理下行物理信道和第一下行信号。
其中，第一下行信息号是除了下行PRS之外的下行信号。
可选地，上述方式1和方式2可以通过协议预定义，或者高层信令通知。
其中，UE定位测量能力等级与UE定位测量能力(如在相同的子帧/时隙内，UE能否进行定位测量和下行处理的能力)和起始时刻T1、持续时间L和结束时刻T2之间的对应关系，如下表2所示，其中，N表示配置的TRP 个数。
表2：
Figure PCTCN2021124125-appb-000002
可选地，针对上述UE定位测量能力等级为等级4和等级5的有效时隙和有效条件判断规则如表3所示。其中，N1和N2为大于等于1的正整数。
表3：
Figure PCTCN2021124125-appb-000003
Figure PCTCN2021124125-appb-000004
可选地，上述表2和表3可以通过协议预定义，或者高层信令通知。
可选地，在所述终端定位测量能力信息包括：在下行激活带宽部分、在相同频段的不同带宽部分、在不同频段内，终端能否同时进行定位测量和下行处理的情况下，终端可以根据表4所示的UE定位测量能力等级与针对带宽的UE定位测量能力之间的对应关系，在目标测量Gap内，进行下行定位参考信号PRS接收和测量。
表4：
Figure PCTCN2021124125-appb-000005
又例如：网络设备可以通过显式配置和隐式配置的方式，为终端配置非周期下行PRS或者半持续下行PRS的目标测量Gap。
当通过显式配置和隐式配置的方式确定的目标测量Gap不一致时，可以采用显式配置的方式确定的目标测量Gap，或者也可以采用隐式配置的方式确定的目标测量Gap；其可由协议约定。
可选地，可以约定显式配置的方式具有较高的优先级，即当通过显式配置和隐式配置的方式确定的目标测量Gap不一致时，以显式配置的方式确定的目标测量Gap为准。

以下结合具体实施例，基于网络设备侧和终端侧对本公开的上述方法进行说明：
实施例一：网络设备(以下以服务基站为例)采用显式信令方式向终端通知非周期或半持续下行PRS的定位测量Gap。其中，N＝8。
针对UE侧的执行过程如下：
步骤1、UE向服务基站上报UE定位测量能力信息。
步骤2、UE接收服务基站发送的非周期/半持续定位测量Gap的显式配置参数。
步骤3、UE根据上述步骤2获得的显式配置参数，分别进行对应处理。
例如：针对显式配置的定位测量Gap，UE在显式配置参数所指示的定位测量Gap，进行下行PRS接收和测量处理，获得定位测量量。
步骤4、UE向网络上报定位测量量，或者基于该定位测量量进行UE位置解算。
针对服务基站侧的执行步骤如下：
步骤1、服务基站根据UE上报的UE定位测量能力信息选择显式方法配置非周期/半持续的定位测量Gap。
例如：针对非周期下行PRS，定位测量Gap是非周期的，并可以采用以下方式定义配置参数。
非周期定位测量Gap的起始时刻T1为网络配置的所有下行小区的非周期下行PRS资源集的起始时刻的最小值；非周期的定位测量Gap的结束时刻T2为网络配置的所有下行小区的非周期下行PRS资源集的结束时刻的最大值；非周期的定位测量Gap的持续时间L1＝T2-T1。
例如：一共配置了N＝8个TRP，T1表示非周期定位测量Gap起始时刻，T2表示非周期定位测量Gap结束时刻，L1表示非周期定位测量Gap的持续时间。
其中，服务基站通过显式信令通知T1、T2和L1之间的任意两个值。显式信令可以是LPP信令、RRC信令、MAC-CE或者DCI信令。
其中，T1＝min{T1(TRP#1),T1(TRP#2),…,T1(TRP#8)}＝T1(TRP#1)；
T2＝max{T2(TRP#1),T2(TRP#2),…,T2(TRP#8)}＝T2(TRP#8)；
L1＝T2-T1＝T2(TRP#8)-T1(TRP#1)。
其中，T1、T2和L1的时间单位可以是子帧或者时隙或者OFDM符号。
示例1：针对室内工厂(InF)场景，最大TRP间隔为300米，传输时延为1微秒(us)，在OFDM符号的CP范围(针对SCS＝15KHz，CP长度为4.6us/5.2us)之内。可参见图2所示，采用时隙为单位，一共配置N＝8个TRP， 每个TRP包含1个下行PRS资源集，每个下行PRS资源集包含4个下行PRS资源，每个下行PRS资源包含6个OFDM符号，所有TRP的下行PRS资源集之间采用连续的时隙分配，即TDM复用方式。因此，每个下行PRS资源集占用2个连续的时隙。8个TRP一共占用16个连续的下行时隙，即L＝2N＝2*8＝16。
又例如：针对半持续定位测量Gap，半持续的定位测量Gap的重复周期等于或者大于半持续下行PRS的重复周期。可选地，本公开实施例中所说的半持续的定位测量Gap的重复周期等于半持续下行PRS的重复周期，可以是指半持续的定位测量Gap的重复周期与半持续下行PRS的重复周期相同，或者两者为整数倍关系。
针对半持续下行PRS的定位测量Gap，可以采用以下方式定义配置参数：在一个半持续下行PRS周期内，半持续的定位测量Gap的起始时刻T1为网络配置的所有下行小区的半持续下行PRS资源集的起始时刻的最小值；半持续的定位测量Gap的结束时刻T2为网络配置的所有下行小区的半持续下行PRS资源集的结束时刻的最大值；半持续的定位测量Gap的持续时间L2＝T2-T1。
例如：一共配置了8个TRP，不同TRP的下行PRS资源集之间采用TDM复用方式，T1表示半持续定位测量Gap起始时刻，T2表示半持续定位测量Gap的结束时刻，L2表示半持续定位测量Gap在一个周期内的持续时间，P表示半持续定位测量Gap的重复周期。
其中，网络设备可以通过显式信令通知T1、T2和L2之间的任意两个值，以及P。显式信令可以是LPP信令、RRC信令、MAC-CE或者DCI信令。
可参见图3所示，采用时隙为单位，一共配置了8个TRP，每个TRP包含1个下行PRS资源集，每个下行PRS资源集包含4个下行PRS资源，每个下行PRS资源包含6个OFDM符号，所有TRP的下行PRS资源集之间采用连续的时隙分配，即TDM复用方式。因此，每个下行PRS资源集占用2个连续的时隙。N个TRP一共占用2N个连续的下行时隙，即L＝2N。半持续下行PRS重复两次，P＝8*8＝64。
其中，T1＝min{T1(TRP#1),T1(TRP#2),…,T1(TRP#8)}＝T1(TRP#1)；
T2＝max{T2(TRP#1),T2(TRP#2),…,T2(TRP#8)}＝T1(TRP#1)；
L＝T2-T1＝6；
T3＝T1+P＝T1+64；
T4＝T2+P＝T2+64。
步骤2、服务基站把非周期/半持续定位测量Gap的配置参数通过信令通知给UE。该信令可以是RRC信令、MAC-CE信令或者DCI信令。
其中，针对半持续定位测量Gap，当半持续定位PRS去激活时，自动失效。
步骤3、服务基站向UE发送非周期/半持续下行PRS。
实施例二：网络设备(如服务基站)采用显式结合隐式信令方式向终端通知非周期或半持续下行PRS的定位测量Gap。
针对终端侧的执行步骤如下：
步骤1、UE向服务基站上报UE定位测量能力信息。
步骤2、UE接收服务基站发送的非周期/半持续定位测量Gap的显式配置参数，以及UE通过协议预定义方式获得非周期定位测量Gap的隐式配置参数。
步骤3、UE根据上述步骤2获得的配置参数，进行处理。
例如：针对显式配置的定位测量Gap，UE在显式配置参数所指示的定位测量Gap，进行下行PRS接收和测量处理，获得定位测量量。针对隐式配置的定位测量Gap，UE根据预定义规则，在配置非周期下行PRS所在的子帧、时隙或者OFDM符号，默认进行下行定位信号接收和测量处理，获得定位测量量。
可选地，在通过显式结合隐式配置的方式中，可以是其中某些参数显示配置，另外一些参数协议预定义(即隐式配置)。
步骤4、UE向网络上报定位测量量，或者基于该定位测量量进行UE位置解算。
针对服务基站侧的执行步骤如下：
步骤1、服务基站根据UE上报的UE定位能力选择或者自主选择显示和隐式方法配置非周期的定位测量Gap。
例如：针对显式结合隐式配置的方法，首先进入步骤1.2，然后进入步骤1.1，如果隐式配置方法的参数和显式配置方法的参数冲突，则以显示配置的参数为准。
步骤1.1、显式配置方法：可参见上述实施例一，为避免重复，这里不再赘述。
步骤1.2、隐式配置方法：隐式配置定位测量Gap，即协议不通过显式信令通知UE的定位测量Gap，而是在配置非周期/半持续下行PRS所在的子帧、时隙或者OFDM符号，通过协议预定义方式默认进行下行定位信号接收和测量处理。
UE根据自身上报给网络的UE定位测量能力，选择在隐式的定位测量Gap内，选择下面方式1处理。
方式1：UE只能进行定位测量操作，不能接收处理其它下行信道/信号。其中，UE定位测量能力等级，与UE定位测量能力和起始时刻T1、持续时间L和结束时刻T2之间的对应关系如上述表2所示。其中，N＝4。
其中，表2中等级4和等级5的有效时隙和有效条件判断规则如表3所示。其中，N1和N2为大于等于1的正整数，例如：N1＝2，N2＝2。
UE定位测量能力等级与针对带宽的UE定位测量能力之间的对应关系如表4所示。
其中，上述方式和表格可以通过协议预定义，或者高层信令通知。
步骤2、服务基站把非周期定位测量Gap的配置参数通过信令通知给UE。该信令可以是RRC信令、MAC-CE信令或者DCI信令。
步骤3、服务基站向UE发送非周期/半持续下行PRS。
