为了便于理解本申请实施例，首先说明以下内容。
本申请实施例中，可选的，目标BWP可为网络配置、预配置或协议约定的用于接收PRS的BWP，即用于测量PRS的BWP。
可选的，目标BWP可以是定位专用BWP，或者定位BWP。比如，这种BWP包含但不限于以下特性，可以由网络配置或协议约定：
1)有较大的带宽(比如100M、200M、400M等)，可用于PRS测量。比如配置目标BWP时，子载波间隔(Sub-Carrier Space，SCS)和/或资源块(Resource Block，RB)数均可以较大，如可通过资源标识符值(Resource Indicator Value，RIV)指示。
可选的，定位专用BWP的带宽和SCS可以配置为载波带宽和SCS一 致。如参见表1，对于某个频段1(Frequency Range 1，FR1)的载波，支持3种SCS，并在某SCS下支持表1中某个RB数对应的带宽，那么可以配置3种定位专用BWP，与载波带宽和SCS一致。同理，如参见表2，对于某个FR2的载波，支持2种SCS，那么可以配置2种定位专用BWP，与载波带宽和SCS一致。

表2：FR1中RB数的传输带宽配置
Figure PCTCN2021105408-appb-000002
2)只有需要测量PRS时，才可以配置或使用该BWP。
3)BWP配置中存在专门的标识信息用于与常规BWP区分，如定位BWP用途(usage)标识、或者专门的BWP ID，如BWP ID>3。
4)具有周期性，用于适应周期性PRS的测量。
5)具有周期偏移。
6)有持续时间(duration)配置，用于指示BWP时域持续生效时间。
7)BWP-inactivetimer(BWP去激活定时器)的定时时长较短，或者没有BWP-inactivetimer配置。
8)BWP-inactivetimer用于指示UE，当一段时间没有定位参考信号的测量或当一段时间没有定位参考信号的测量和数据的调度(是否有业务)，则切换至默认BWP或常规BWP。
可选的，目标BWP可以是常规的BWP，比如用于正常数据传输的BWP，若常规BWP也可以满足定位测量的需求，那么也可以用于定位测量。
本申请实施例中，可选的，终端在根据接收到的BWP激活信令切换至目 标BWP之前，还可以获取一个或多个目标BWP配置信息，该目标BWP配置信息由网络侧配置、预配置或协议约定。
本申请实施例适应的场景包括但不限于工业物联网(Industrial Internet of Things，IIoT)场景等。考虑到IIoT定位中的时延(latency)要求，目标BWP可以是预配置或协议约定的BWP。比如，预配置或约定几个固定的带宽(bandwidth)和/或参数集(numerology)的BWP为目标BWP。为了减小时延，IIoT场景中的PRS和定位频率层(positioning frequency layer)可能只存在一个，且PRS或positioning frequency layer的中心频点与网络配置的BWP(如当前激活的BWP)的中心频点一致。那么，终端测量当前激活的BWP外的PRS时，只需要做同频的BWP适应(adaption)就可以。因此，只需网络预配置或者约定几个固定的bandwidth和/或numerology的BWP即可。
本申请实施例中，BWP配置信息可以包括以下参数至少之一：
BWP标识(ID)；
BWP子载波间隔(SCS)；
BWP循环前缀(Cyclic Prefix，CP)类型；
资源标识符值(RIV)；
BWP用途(usage)，该BWP usage用于指示BWP是否为用于测量PRS的BWP；
BWP频域位置信息。
可选的，BWP子载波间隔和BWP循环前缀类型还可以称为BWP的参数集(numerology)。
可选的，BWP usage中，可以是通过如下信息元素(Information Element，IE)：enum{pos}来指示BWP是专用于定位的BWP还是常规BWP。进一步的若配置了{pos}，则该BWP为专门用于接收PRS的BWP，否则该BWP为常规BWP。
可选的，BWP频域位置信息可以包含BWP的起始频域位置及BWP带宽信息。
可选的，上述BWP配置信息还可以包括：定位辅助数据；该定位辅助数据至少包括PRS时频域位置信息。
进一步可选的，该PRS频域位置信息为相对于BWP的频域信息，即这里给出的PRS频域位置信息并不是绝对的频域位置，而是相对于BWP频域位置的位置。
可选的，上述BWP配置信息还可以包括：下行信道和/或下行信号关联的配置信息，比如物理下行共享信道(Physical Downlink Shared Channel，PDSCH)和/或物理下行控制信道(Physical Downlink Control Channel，PDCCH)配置信息等。该下行信道包括控制信道和/或数据信道。这些信道和/或信号可以在目标BWP上传输。
可选的，本申请实施例中，上述的定位参考信号PRS可以理解为用于定位的参考信号，包含但不限于下行定位参考信号PRS、同步信号块(Synchronization Signal and PBCH block，SSB)、信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)、跟踪参考信号(Tracking Reference Signal，TRS)等等。
本申请实施例中，位置服务器与终端之间的信令包含但不限于以下之一：
LTE定位协议(LTE Positioning Protocol，LPP)信令、NR定位协议(NR Positioning Protocol，NRPP)信令、NRPPa与(gNB与UE之间信令)的组合、LPPa与(gNB与UE之间信令)的组合。
可选的，gNB与UE之间的信令包含但不限于以下至少一项：
无线资源控制(Radio Resource Control，RRC)信令、媒体接入控制控制单元(Media Access Control Control Element，MAC CE)、下行控制信息(Downlink Control Information，DCI)、消息1(Msg1)、消息3(Msg3)、广播信令、寻呼(Paging)信令等等。
可选的，gNB与位置服务器之间的信令包含但不限于以下之一：NRPPa、LPPa等。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的定位测量方法进行详细地说明。
请参见图2，图2是本申请实施例提供的一种定位测量方法的流程图，该方法应用于终端，如图2所示，该方法包括如下步骤：
步骤201：切换至目标BWP。
本实施例中，目标BWP可以是常规BWP或定位专用的BWP。目标BWP所在的服务小区可称为目标服务小区。该目标服务小区可以是常规或定位专用的服务小区。
可选的，目标BWP所在的目标服务小区可以为以下任意一项：激活的服务小区、已配置但未激活的服务小区、未配置的服务小区。
一种实施方式中，该目标服务小区可为主小区组(Master Cell Group，MCG)和辅小区组(Secondary Cell Group，SCG)中的主小区(Primary cell，Pcell)、特殊小区(Special cell，Spcell)、主辅小区(Primary secondary cell，Pscell)、辅小区(Secondary cell，Scell)中的之一。
比如，上述已配置但未激活的服务小区可为已配置的scell，但需要MAC CE信令激活。
又比如，上述未配置的服务小区需要gNB通过RRC重配信令添加。
需指出的，上述服务小区(serving cell)还可以称为分量载波(Component Carrier，CC)或载波。在切换至目标BWP以执行PRS测量的情况在，在同一正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号上，PRS与下行信道或信号可以复用在不同的RB上。
步骤202：在目标BWP中执行PRS测量。
本实施例中，终端在执行PRS测量时，可以根据PRS的配置，对该PRS执行测量。需指出的，PRS的配置还可以理解为定位频率层(positioning frequency layer)的配置。终端对某个或某几个定位频率层的测量可以切换至目标BWP上执行。
在一些实施例中，终端在目标BWP上也可以执行多个定位频率层的测量。相应的，终端对目标BWP的请求也可以是基于多个定位频率层的配置综合得出的BWP请求。相应的，终端对PRS的测量也可以是对某个或某几个定位频率层的测量。
在本申请实施例中，终端可以切换至目标BWP，并在该目标BWP中执行PRS测量。由此，终端在执行PRS测量时，可以切换到满足条件的合适的目标BWP上实现，从而既可以完成PRS测量，又可以不中断数据传输，从而解决现有的利用measurement gap执行PRS测量的方法造成的中断数据传 输的问题。
本申请实施例中，在执行PRS测量之前，终端还可以接收服务基站发送的目标信令，以根据该目标信令，在目标BWP中执行PRS测量。需指出的，根据该目标信令确定的目标BWP可以有1个或多个。

目标BWP的激活信令；其中对于目标BWP的激活，可以是激活1个或多个目标BWP；比如，将新激活或新添加的服务小区(如scell)的第一激活BWP切换至目标BWP。
可选的，目标BWP可以为激活的目标服务小区中的第一激活BWP(first active DL BWP)，或者，目标BWP可以为添加的目标服务小区中的第一激活BWP(first active DL BWP)。
可选的，在目标BWP上执行PRS测量的情况下，终端可以向该服务基站发送第一请求信令，该第一请求信令用于指示终端将(或期望)在目标BWP执行PRS测量。需指出的，此处的“期望”也可以表述为偏好的(preference)。比如，当UE期望测量当前激活BWP外的PRS，或者numerology与当前BWP不同的PRS时，UE请求在目标BWP执行PRS测量。而UE请求的目标BWP和服务基站指示的目标BWP可以相同也可以不同。
一种实施方式中，终端可以在接收服务基站发送的目标信令之前，向该服务基站发送第一请求信令。

-比如，该目标服务小区配置信息可包括以下至少一项：服务小区所在的频带band标识、服务小区A点(point A)位置信息、服务小区起始位置信息、服务小区带宽、子载波间隔等。这里point A为参考点A，即频域位置以这个频点为参考，比如指示某个频域位置时，可以根据某子载波间隔下，高于这个频点N个RB来确定。
11)部分或者全部的PRS配置信息。可选的，该PRS配置信息可包含但不限于PRS频域信息、PRS时域信息等。

-又比如，该PRS时域信息可包括但不限于以下至少一项：PRS时域位置信息、PRS周期及周期偏移、PRS occasion(时机)配置信息、PRS重复配置信息等等。

18)当前位置服务或定位测量的优先级。其中，该优先级可用于辅助服务基站判断是否接受相应请求和/或确定后续行为。比如，若PRS测量的优先级为高，则服务基站将切换至目标BWP用于PRS测量，即使增大了信令开销或功耗。或者，当前位置服务或定位测量的重要程度。其中，该重要程度可用于辅助服务基站判断是否接受相应请求和/或确定后续行为。比如，若PRS测量的重要程度为高，则服务基站将切换至目标BWP用于PRS测量，即使增大了信令开销或功耗。
需指出的，上述的优先级或重要可分多个等级，比如等级0,1,2,3…，其中0代表最高等级；终端可以指示优先级或重要程度为这些等级中的一种。
需要说明的是，在所述目标BWP中执行下行定位参考信号测量的优先级(或重要程度)可以由所述位置服务器指示或所述终端确定或预配置或协议约定。例如，在由所述终端确定时，所述终端可根据接收到的如服务质量QoS等定位请求信息确定，本实施例对此不做限制。
20)不请求测量间隔(measurement gap)的理由。比如，UE不期望数据传输中断时间过长，或者存在符合条件的BWP配置等。
21)测量间隔(measurement gap)的请求标识。可理解的，当包含了这个参数时，该参数用于指示服务gNB，若拒绝UE在目标BWP执行PRS测量，服务gNB可以配置measurement gap用于PRS测量。进一步的，第一请求信令还可以包含UE期望的measurement gap配置信息等等。
需指出的，在本申请实施例中，第一请求信令可以通过RRC信令传输，比如可以包含在measurement gap的请求信令中通过RRC发送至服务gNB。第一请求信令可以是包含1个将某个激活的BWP切换至另一目标BWP请求的信令，也可以是包含将N(N为大于1的整数)个激活的BWP切换到对应的N个目标BWP的请求的信令。当然，第一请求信令还可以包含新的BWP的激活请求。这种新的BWP激活，并不是从当前的激活的BWP切换过来的，而是需要先激活或添加scell后，再进行激活的BWP。当然，上面这些不同的BWP切换或激活请求，可以由一条信令携带，也可以由多条请求信令分别携带。比如每条信令携带一个BWP切换或激活请求。比如每个BWP切换或激活请求和一个定位频率层对应/关联。
本申请实施例中，在向服务基站发送第一请求信令之后，如果服务基站拒绝该第一请求信令，可以向终端反馈拒绝响应。对应的，终端可以接收服务基站反馈的拒绝响应。

本申请实施例中，终端还可向位置服务器发送反馈信息，其中该反馈信息包括：用于指示终端是否向服务基站发送了第一请求信令的第一指示信息。 这样借由第一指示信息，可使得位置服务器获知终端是否向服务基站发送了第一请求信令，以请求在目标BWP中执行PRS测量。

本申请实施例中，在目标BWP上执行PRS测量的情况下，终端还可以向服务基站发送第二请求信令。其中，该第二请求信令可以用于指示终端将停止在目标BWP上执行PRS测量。
一种实施方式中，终端可以在向服务基站发送第一请求信令之后，再向服务基站发送第二请求信令。
进一步的，该第二请求信令还可以用于指示服务基站执行以下操作中的至少一项：

需指出的，对于包含BWP配置信息的定位测量结果，可以隐含地表示该定位测量结果不是在measurement gap中执行测量获得的。若终端未请求measurement gap，且未请求目标BWP，则终端在定位测量结果中还可以上报指示未请求measurement gap且未请求目标BWP的信息。
本申请实施例中，在定位测量结果包括多个服务小区(CC)的测量结果的情况下，终端在上报定位测量结果时，可以分别向每个服务小区上报各自的测量结果。这样，可以便于服务小区获知各自的测量结果。
比如，若该定位测量结果包括CC1的测量结果1、CC2的测量结果2和CC3的测量结果3，则终端针对CC1上报测量结果1，针对CC2上报测量结果2，针对CC3上报测量结果3。

可选的，当终端配置了测量间隔(measurement gap)，且在该测量间隔内目标服务小区激活或去激活时，终端可以在该测量间隔中执行PRS测量。此情况下，measurement gap的优先级高于服务小区激活和去激活的优先级。换句话说，在测量间隔期间，终端不期望进行服务小区的激活或去激活。
此外，若终端配置了measurement gap，且在measurement gap内目标服务小区激活或去激活，终端还可以中断measurement gap中的PRS测量，比如，PRS有多个测量周期实例instance，中断某个测量周期instance的PRS测量。此情况下，measurement gap的优先级低于服务小区激活和去激活的优先级。换句话说，在服务小区激活或去激活期间，终端不期望被配置测量间隔执行PRS测量，或者终端不期望执行PRS测量。
一种实施方式中，在定位测量时，终端不期望同时配置measurement gap和服务小区的激活/去激活。
可选的，当终端接收到目标服务小区的去激活信令，且该目标服务小区的去激活信令中包括测量间隔的配置的指示时，终端根据该目标服务小区的去激活信令，可以在配置的测量间隔中执行PRS测量或继续执行PRS测量，以保证PRS测量的顺利执行。

需指出的，该第三指示信息可以理解为1个开关。在有该第三指示信息的情况下，当UE期望测量激活BWP外或者numerology与激活BWP不同的PRS时，UE就可以请求BWP切换或者请求measurement gap。在没有该第三指示信息的情况下，UE只能请求measurement gap。
可选的，在执行PRS测量之前，当终端支持请求测量间隔，和支持请求目标BWP切换或激活时，终端可以从位置服务器和服务基站中的至少一者接收第四指示信息，该第四指示信息用于指示测量间隔和BWP切换的优先级，并根据该第四指示信息，向位置服务器请求测量间隔，并在测量间隔中执行PRS测量，或者根据该第四指示信息，向位置服务器请求目标BWP切换或激活，并在目标BWP中执行PRS测量。
需指出的，对于上述优先级，除了可以由网络指示外，还可以由协议约定、预配置、预定义和终端选择其中之一确定。比如，协议约定measurement gap请求优先级高于BWP切换的优先级，或者measurement gap请求优先级低于BWP切换的优先级、或者measurement gap请求优先级与BWP切换的优先级相同。
本申请实施例中，UE在目标BWP执行PRS测量，可以至少包含以下几种情况：

请参见图5A，图5A是本申请实施例提供的另一种定位测量方法的流程图，该方法应用于终端，如图5A所示，该方法包括如下步骤：
步骤501：获取定位测量的测量间隔。
需指出的，为了完成定位，终端一般需要测量多个小区广播发送的PRS。为了保证高精度的定位，网络侧设备会配置较大的带宽的PRS，通常PRS带宽越大，定位精度越高。大带宽的PRS有时候会超出终端当前工作的激活(active)BWP的范围，因此为了终端测量active BWP外的PRS，可允许终端使用测量间隔(measurement gap)测量active BWP外的PRS。
一种实施方式中，终端可以向服务基站发送请求信令，请求配置measurement gap。服务基站决定如何配置measurement gap，随后向终端下发measurement gap配置，终端可以使用配置的measurement gap测量PRS。
步骤502：在所述测量间隔中执行PRS测量。
本申请实施例中，终端可以获取定位测量的测量间隔，并在该测量间隔中，执行PRS测量；由此，可以实现终端的PRS测量，尤其是可以实现终端使用测量间隔测量active BWP外的PRS。
本申请实施例中，可选的，当终端配置了测量间隔，且在该测量间隔内有服务小区激活或去激活时，终端可以在该测量间隔中执行PRS测量。此情况下，measurement gap的优先级高于服务小区激活和去激活的优先级。换句话说，在测量间隔期间，终端不期望进行服务小区的激活或去激活。
此外，若终端配置了measurement gap，且在measurement gap内有服务小区激活或去激活，终端还可以中断measurement gap中的PRS测量，比如，PRS有多个测量周期instance，中断某个测量周期instance的PRS测量。此情况下，measurement gap的优先级低于服务小区激活和去激活的优先级。换句话说，在服务小区激活或去激活期间，终端不期望被配置测量间隔执行PRS测量，或者终端不期望执行PRS测量。
一种实施方式中，在定位测量时，终端不期望同时配置measurement gap和服务小区的激活/去激活。
可选的，在服务小区的激活或去激活信令中携带有所述测量间隔的配置的情况下，终端可以根据服务小区的激活或去激活信令，在配置的测量间隔中执行PRS测量，以保证PRS测量的顺利执行。
可选的，当终端的请求测量间隔可以由服务小区激活或去激活触发时，终端可以获取目标服务小区的激活或去激活信令，并根据服务小区的激活或去激活信令，向服务基站请求测量间隔，以在请求到的测量间隔执行PRS测量。
