在本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“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可选或更具优势。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。
下面结合附图介绍本公开的实施例。本公开实施例提供的PRS资源配置方法、终端和网络设备可以应用于无线通信系统中。该无线通信系统可以为5G系统，或者演进型长期演进(Evolved Long Term Evolution，eLTE)系统，或者LTE系统，或者后续演进通信系统等。
请参见图1，图1是本公开实施例可应用的一种网络系统的结构图，如图1所示，包括终端11和多个网络设备，在此以所述多个网络设备为3个为例，即：第一网络设备12、第二网络设备13和第三网络设备14，其中，终端11可以是用户终端(User Equipment，UE)或者其他终端侧设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开实施例中并不限定终端11的具体类型。上述网络设备可以是4G基站，或者5G基站，或者以后版本的基站，或者其他通信系统中的基站，或者称之为节点B，演进节点B，或者传输接收点(Transmission Reception Point，TRP)，或者接入点(Access Point，AP)，或者所述领域中其他词汇，只要达到相同的技术效果，所述网络设备不限于特定技术词汇。另外，上述网络设备可以是主节点(MN，Master Node)，或者辅节点(SN，Secondary Node)。需要说明的是，在此并不限定网络设备的具体类型。
请参见图2，图2是本公开实施例提供的一种PRS资源配置方法的流程图，该方法应用于终端，如图2所示包括以下步骤：
步骤201、根据PRS资源的起始PRB位置和PRB数目，确定BWP内PRS的资源位置。
其中，上述PRS资源可以是服务小区配置的PRS资源，或者上述PRS资源可以是邻小区配置的PRS资源。进一步的，上述PRS资源可以在公共资源块网格(common resource block grid)中PRS的资源位置，该PRS资源的 位置可以由该PRS资源的起始PRB位置(starting RB)与该PRS占用的PRB数目(nrofRBs)确定。
终端可以通过以下任一种方式确定PRS资源的起始PRB位置、PRB数目及频域粒度：
网络配置；
协议规定；
协议规定多个值，由网络侧指示其中的一个值。
其中，上述网络配置可以是网络设备向终端配置起始PRB位置、PRB数目及频域粒度中的至少一项，例如：通过终端与位置服务器之间的LTE定位协议(LTE Positioning Protocol，LPP)向终端配置起始PRB位置、PRB数目及频域粒度中的至少一项，或者，可以通过终端与网络设备之间的其他定位协议向终端配置起始PRB位置、PRB数目及频域粒度中的至少一项，对此不作限定。
另外，上述协议规定多个值，由网络侧指示其中的一个值可以是，通过LPP信令来指示其中的一个值，当然，对此不作出限定，例如：也可以通过RRC信令或者其他信令为指示。
另外，上述确定BWP内PRS的资源位置过程，可以应用于测量间隔(measurement gap)未被配置的情况。目前的定位技术中在没有配置测量间隔的情况下，由于目标定位技术中，提供给终端的下行PRS配置与DL BWP配置独立，这样如果采用目前的定位技术，会存在终端很难准确地测量到PRS的问题。本公开实施例中，在没有配置测量间隔的情况下，根据PRS资源的PRB位置和PRB数目，确定BWP内PRS的资源位置，以提高终端检测到PRS的概率，进而可以使终端根据确定后的BWP内PRS的资源位置准确地测量到PRS。
另外，需要说明的是，上述BWP内PRS的资源位置也可以理解为BWP内的PRS资源，或者终端在BWP内可测量PRS的资源位置。
另外，上述BWP可以是一个或者多个BWP，进一步的，可以是一个或者多个激活BWP(active BWP)。
步骤202、在所述资源位置上执行测量。
该步骤中，终端可以在所述资源位置上执行测量来自多个小区或者多个传输点发送的PRS，以测量得到多个小区或者多个传输点之间的RSTD和RSRP中的至少一项，之后，将测量得到的结果发送给网络设备进行定位。
通过上述步骤可以使得终端能够在该资源位置上检测到PRS，提升了终端检测到PRS的概率。
作为一种可选的实施方式，所述确定BWP内PRS的资源位置，包括：
确定所述BWP内PRS资源的初始公共资源块(common resource block，CRB)索引，以及所述BWP内PRS资源的带宽。

进一步的，在所述起始PRB位置的索引小于所述BWP的起始PRB索引的情况下，所述初始CRB的索引为所述BWP的起始PRB索引；或者
在所述起始PRB位置的索引大于或者等于所述BWP的起始PRB索引的情况下，所述初始CRB的索引为所述起始PRB位置的索引。
该实施方式中，可以准确地BWB内PRS的资源位置。
更进一步的，在所述起始PRB位置的索引大于或者等于所述BWP的起始PRB索引，且所述初始CRB的索引为所述起始PRB位置的索引的情况下，若

其中，startingRB为所述起始PRB位置的索引，

为所述BWP的带宽，N initial RB为所述初始CRB的索引，

另外，若
Figure PCTCN2020085646-appb-000012
则终端不对该PRS资源执行测量。
在应用过程中，可以通过网络设备发送的指示信息或者协议预配置的方式控制终端执行上述确定BWP的带宽的步骤。
本实施方式中，可以根据startingRB、

nrofRBs、
Figure PCTCN2020085646-appb-000014
以及N initial RB之间的数量关系，确定所述

的取值，以准确地确定BWB内PRS的
Figure PCTCN2020085646-appb-000016
。
作为一种可选的实施方式，所述在所述资源位置上执行测量，包括：
若所述PRS资源的参数配置(numerology)与所述BWP的numerology匹配，则在所述资源位置上执行测量。
其中，上述PRS资源的numerology与所述BWP的numerology匹配可以是，上述PRS资源的numerology与所述BWP的numerology相同或者相似。
该实施方式中，PRS资源的numerology与所述BWP的numerology匹配的情况下，才执行测量，从而可以节约终端的功耗。
进一步的，可以是在没有配置测量间隔的情况下，且PRS资源的numerology与所述BWP的numerology匹配的情况下，才执行测量。也就是说，在没有配置测量间隔的情况下，若所述PRS资源的numerology与所述BWP的numerology不匹配，则终端不在该PRS资源内执行测量。其中，这里的不匹配可以是PRS资源的numerology与所述BWP的numerology全部或者部分不同。
当然，在一些实施方式中，若配置有测量间隔，且PRS的numerology与所述BWP的numerology不同，则终端也可以不对该PRS资源执行测量。
需要说明的是，在上述不匹配的情况下，本公开实施例中，可以通过图3所示的实施例中发送第一信令，以使得网络设备配置与第一信令对应的测量间隔，使得终端执行测量，具体可以参见图3所示的实施例。
作为一种可选的实施方式，所述PRS资源的频域粒度为1RB、2RB、4RB或8RB；
其中，在所述频域粒度为1RB的情况下，所述起始PRB位置的索引为(0,1,2,3..275*8-1)中一数值，所述PRB数目为(Xmin,Xmin+1,Xmin+2…Xmax)中一数值，其中，Xmin取值为1、11、12、24或25，Xmax为264、272、273、 275或2200；或者
在所述频域粒度为2RB的情况下，所述起始PRB位置的索引为(0,2,4,8..2198)中一数值，所述PRB数目为(Xmin,Xmin+2,Xmin+4…Xmax)中一数值，其中，Xmin取值为2、12或24，Xmax为264、272、274、276或2200；或者
在所述频域粒度为4RB的情况下，所述起始PRB位置的索引为(0,4,8,..2196)中一数值，所述PRB数目为(Xmin,Xmin+4,Xmin+8…Xmax)中一数值，Xmin取值为4、12或24，Xmax取值为264、272、276或2200；或者
在所述频域粒度为8RB的情况下，所述起始PRB位置的索引为(0,8,16,24..2192)中一数值，所述PRB数目为(Xmin,Xmin+8,Xmin+16…Xmax)，Xmin取值为8、16或24，Xmax取值为264、272、280或2200。
本实施方式中，可以根据PRS资源的频域粒度的取值，确定起始PRB位置的索引和PRB数目的取值范围，从而简化了确定起始PRB位置的索引和PRB数目的过程。
作为一种可选的实施方式，若所述PRS资源跨多个载波单元(Component Carrier，CC)中的多个BWP，所述确定BWP内PRS的资源位置，包括：
确定所述多个BWP内的PRS的资源位置；
所述在所述资源位置上执行测量，包括：
在所述多个BWP中的全部或者部分BWP内的PRS的资源位置上执行测量。
需要说明的是，同一时刻，同一载波，终端只可以工作在1个激活BWP(active BWP)上。例如：PRS资源跨N个CC，则PRS就可能跨M个BWP，其中，M<＝N。也就是说，所述PRS资源跨多个CC中的多个BWP可以表示为：PRS资源跨N个CC中的M个BWP。该实施方式下，终端以在这M个BWP上测量PRS。
本实施方式中，可以在PRS资源跨多个CC中的多个BWP的情况下，通过在所述多个BWP中的全部或者部分BWP内的PRS的资源位置上执行测量，实现对跨多个CC中的多个BWP的PRS资源的测量，从而提升了测量 过程的适用性。
在实施中，所述部分BWP可以包括：

在终端需要将测量结果上报至网络设备，在一种实施方式中，终端不对全部或者部分BWP中测量得到的测量结果进行联合，而是分别将所述全部或者部分BWP中测量得到的测量结果进行上报，在另一种实施方式中，终端将所述全部或者部分BWP中的PRS资源进行联合后得到的资源上进行测量得到的测量结果进行上报，或者将所述全部或者部分BWP中测量得到的测量结果进行平均或者加权平均得到的测量结果进行上报，以将多个BWP中测量得到的测量结果联合成一个测量结果。
在实际应用中，终端具体采用哪一种上报方式对测量结果进行上报，可 以基于网络指示、预设协议规定或者终端自主选择等方式确定。

请参阅图3，是本公开实施例提供的一种测量间隔配置方法的流程图，该方法应用于终端，如图3所示，该方法包括以下步骤：
步骤301、发送第一信令，所述第一信令用于辅助网络设备进行用于测量PRS的测量间隔的配置。
在具体实施中，所述测量间隔也可以称之为：measurement gap，在配置测量间隔的情况下，终端可以通过配置的measurement GAP测量激活BWP(例如：active DL BWP)外的PRS。或者，在配置测量间隔的情况下，终端可以通过配置的measurement GAP测量与激活BWP numerology不同的PRS。
另外，网络设备在接收到所述第一信令的情况下，根据该第一信令对用于测量PRS的测量间隔进行配置，例如：网络设备通过RRC信令或者LPP信令配置相应的测量间隔。或者网络侧在接收到所述第一信令的情况下，也可以不配置测量间隔。其中，配置或者不配置测量间隔，由网络侧决定。
本实施方式中，在终端需要所述测量间隔进行测量的情况下，通过终端发送所述第一信令，实现了使网络设备根据该第一信令配置所述测量间隔， 从而提高终端测量到PRS的概率。
目前的定位技术中，由于测量间隔与PRS的配置相对独立，从而使得终端很难准确地测量到PRS。本公开实施例中，在需要配置测量间隔的情况下，通过终端发送第一信令，以使网络设备根据所述第一信令用于进行用于测量PRS的测量间隔的配置，以提高终端检测到PRS的概率，进而可以使终端能够准确地测量到PRS。
作为一种可选的实施方式，所述第一信令为向网络设备发送的信令，所述第一信令用于指示所述终端期望的测量间隔配置；
或者，所述第一信令为向网络设备发送的包括定位辅助信息的信令，且所述第一信令用于指示配置与所述定位辅助信息关联的测量间隔配置。
该实施方式中，在所述第一信令用于指示所述终端期望的测量间隔配置的情况下，可以按照所述终端的期望对所述测量间隔进行配置，从而提升了配置的测量间隔与终端之间的匹配程度。另外，在所述第一信令用于指示配置与所述定位辅助信息关联的测量间隔配置的情况下，可以按照定位辅助信息的需求对测量间隔进行配置，从而提升了配置的测量间隔与定位辅助信息之间的匹配程度。
在具体实施中，所述网络设备为服务基站，也就是说，终端向服务小区(serving cell)发送上述信令。

其中，上述指示的终端使用测量间隔执行测量可以是，终端将开始使用测量间隔执行测量，或者终端立马使用测量间隔执行测量，或者终端已经准确使用测量间隔执行测量。
该实施方式中，终端通过第一信令告知网络设备，即将开始使用测量间隔执行测量或者请求使用测量间隔执行测量，从而使网络设备在接收到该第一信令的情况下，做出相应的反馈，例如：同意终端使用所述测量间隔执行 测量并为终端配置相应的测量间隔等。
进一步的，在所述第一信令用于指示所述终端期望的测量间隔配置的情况下，所述第一信令可以包括如下至少一项：
PRS资源的频率信息、PRS测量偏移信息、测量间隔图样标识信息(measurement gap pattern ID)、测量间隔定时提前量(measurement gap timing advance)和测量间隔的数量。
上述PRS测量偏移信息可以NR系统中的PRS测量偏移信息(measurement NR PRS offset)，用来向网络侧指示终端测量PRS时需要的gap offset。所述PRS可以是服务小区发送的PRS，也可以是邻小区发送的PRS。所述gap offset可以是终端根据服务小区和/或邻小区PRS的时域信息，计算得到的偏移量。所述gap offset可以是距离服务小区系统帧号(System Frame Number，SFN)0中subframe0起点的subframe偏移。
同样的，所述测量间隔图样标识信息、测量间隔定时提前信息都可以是终端E根据PRS时域信息得到。
所述测量间隔的数量也可以根据终端的需求得到。测量间隔的数量可以是1个或者多个。若1个测量间隔无法满足UE对服务小区或邻小区PRS的测量，UE可以请求配置多个测量间隔。
其中，上述测量间隔图样标识信息可以表示用户希望的测量间隔，以及还可以表示终端不期望的测量间隔。
在具体实施中，可以使网络设备为用于测量所述PRS的测量间隔与所述终端上的PRS资源的频率信息、PRS测量偏移信息、测量间隔图样标识信息、测量间隔定时提前量等适配，从而提升了PRS资源配置的准确性。
在具体实施中，所述定位辅助信息可以包括如下至少一项：
PRS资源的搜索窗信息、PRS时域配置信息、PRS静默图样信息(PRS muting pattern)和小区定时信息。
其中，上述PRS时域配置信息可以包括：PRS周期、时域偏移和PRS的测量时机(occasion)信息。
作为一种可选的实施方式，所述方法还包括：
发送第二信令，所述第二信令用于指示所述网络设备所述终端将停止使 用测量间隔的执行测量。
本实施方式中，终端可以通过发送第二信令，告知网络设备所述终端将停止使用测量间隔的执行测量，这样，网络设备可以在终端停止使用测量间隔的执行测量之后，停止对该测量间隔的相关处理，例如：网络设备通过RRC信令配置测量间隔停止，从而减少了网络设备上资源的占用。
作为一种可选的实施方式，所述发送第一信令，包括：
若PRS资源不在所述终端的激活BWP内，则发送第一信令；或者

需要说明的是，该实施方式中的上述PRS资源可以参见图2所示的实施例中的相关描述，例如：可以由服务小区或者邻小区配置，此处不作赘述。
需要说明的是，在实际应用中，终端还可以在PRS完全包含在终端的激活BWP内等情况下，不发送所述第一信令。本实施方式中，可以在需要终端发送第一信令，以辅助网络设备进行用于测量PRS的测量间隔的配置的情况下，控制终端发送所述第一信令，在其余情况下，不发送所述第一信令，从而减少了第一信令对终端资源的占用。
进一步的，所述满足第一条件可以是指如下至少一项：
所述PRS资源在所述终端的激活BWP内的部分资源的带宽小于带宽门限；
所述PRS资源在所述终端的激活BWP内的部分资源的带宽达不到测量精度要求；

需要说明的是，在实际应用中，上述第一条件可以通过网络设备的预配置、预设协议的规定或终端的自主选择等方式进行选择和确定。
本实施方式中，可以在所述PRS资源在所述终端的激活BWP内的部分资源的带宽小于带宽门限或者所述PRS资源在所述终端的激活BWP内的部分资源的带宽达不到测量精度要求，且PRS资源有部分资源在所述终端的激活BWP内的情况下，确定需要终端发送第一信令，以辅助网络设备进行用于测量PRS的测量间隔的配置，并据此控制终端发送所述第一信令，为是否发送第一信令提供了判断依据。
作为一种可选的实施方式，所述第一信令为定位能力上报信令，且所述定位能力上报信令包括BWP带宽信息。
其中，上述定位能力上报信令可以是用于上报终端LPP能力信息的上报消息，例如：在LPP能力信息上报的字段中，上报BWP带宽等信息

需要说明的是，本公开实施例中提供的多种PRS资源配置方法可以相互 结合实现，例如：在图3所示的实施例中，指示停止使用测量间隔的执行测量的情况下，可以采用图2所示的确定PRS资源配置的确定BWP内的资源位置，并执行测量。当然，本公开实施例提供的PRS资源配置方法的多种实施方式也可以单独进行，例如：以下通过四个方案进行举例说明：
实施例1：
PRS资源在公共资源块网格(common resource block grid)中的位置可由该PRS资源的起始PRB位置(startingRB)与该PRS占用的PRB数(nrofRBs)决定。该PRS资源的起始PRB位置为该PRS资源最低PRB相对于(CRB#0)的RB偏移。该PRS资源占用的PRB数为该PRS资源跨的PRB的数量(Number of PRBs across which this PRS resource spans)。

终端上报带宽最大的N个BWP上的PRS资源的测量结果，N可以为1；
终端上报带宽超过门限的N个BWP上的PRS资源的测量结果；
终端上报某1个或多个CC中BWP的测量结果；
(2)终端对多个CC或BWP上的测量的PRS资源进行联合处理，上报综合多个CC或BWP后的测量结果。联合处理方法可以是以下方法之一：
终端对多个CC或BWP上的测量的结果取平均或加权平均后上报；
终端联合多个CC或BWP上可测的PRS资源，等效为1个大带宽的PRS资源，对大带宽的PRS资源进行处理后上报。
终端上报方式可以由网络指示，协议规定或UE选择。
上报内容中可包含：Pcell标识/Scell标识，BWP ID，PRS resource ID，PRS resource set ID，TRP/cell ID等至少其中一项。

；
在measurement gap可以被配置时，终端可以向serving cell发送请求信令，请求measurement gap配置。或者终端在LPP能力信息中上报BWP相关信息，由LMF直接配置measurement gap；
PRS资源带宽跨CC传输时，UE可同时在多个DL active BWP上测量PRS资源。终端可以在全部或部分BWP上执行测量，终端可以按照BWP或CC上报测量结果或联合处理后上报综合的测量结果。
