Description

用途指示、确定方法和装置、通信装置和存储介质 技术领域
本公开涉及通信技术领域，具体而言，涉及用途指示方法、用途确定方法、用途指示装置、用途确定装置、通信装置和计算机可读存储介质。
背景技术
5G NR(New Radio，新空口)引入了多种定位技术，可以实现对UE(User Equipment，用户设备)的定位。其中的一些定位技术，需要网络向UE提供定位辅助信息，例如定位参考信号(Positioning Reference Signal，PRS)配置。
在定位过程中向UE发送定位辅助信息，会导致时延增加。为了降低时延，相关技术中采用了为UE预配置定位辅助信息的方式，也即在对UE进行定位之前，网络侧设备就将定位辅助信息配置给UE。
另外，网络侧设备还可以为UE配置按需请求(on-demand)的PRS配置，按需请求的PRS配置例如可以是包括多个PRS配置的集合，UE在从集合中选取一个PRS配置并向网络侧设备发送请求，以请求该配置。
在网络侧设备既适用于为UE预配置定位辅助信息时，又适用于为UE配置按需请求的PRS配置时，就需要信令中既携带预配置定位辅助信息，又携带配置按需请求的PRS配置，定位辅助信息和按需请求的PRS配置一般需要占用较多的比特，导致信令开销较大。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。
图1是根据本公开的实施例示出的一种用途指示方法的示意流程图。本实施例 所示的用途指示方法可以由网络侧设备执行，所述网络侧设备包括但不限于基站、核心网，所述网络侧设备可以与作为用户设备的终端通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图1所示，所述用途指示方法可以包括以下步骤：
在步骤S101中，向终端发送定位参考信号PRS配置集合；
在步骤S102中，向所述终端指示所述PRS配置集合的用途。
在一个实施例中，所述网络侧设备既可以为终端预配置定位辅助信息，又可以为终端配置按需请求的PRS配置，其中，定位辅助信息可以包括PRS配置，终端可以根据PRS配置接收PRS，进而根据接收到的PRS进行定位过程。
在这种情况下，网络侧设备如果通过信令既携带PRS配置作为预配置的PRS配置发送给终端，又携带PRS配置集合作为按需请求的PRS配置发送给终端，将会占用较多的信令资源，导致信令开销较大，例如需要通过在信令中设置两个信息元素(Information Element，IE)，一个IE携带PRS配置作为预配置的PRS配置，另一个IE携带PRS配置集合作为按需请求的PRS配置。
根据本公开的实施例，网络侧设备只需通过一条信令携带PRS配置集合发送给终端，并向终端指示PRS配置集合的用途，而无需通过信令既携带预配置的PRS配置，又携带按需请求的PRS配置，有利于节约信令资源。
在一个实施例中，网络侧设备可以通过显式和/或隐式的方式向所述终端指示所述PRS配置集合的用途。
以显式方式为例，网络侧设备可以向终端发送用途指示，以指示PRS配置集合的用途。其中，PRS配置集合的用途包括3种，也即PRS配置集合中的PRS配置作为终端按需请求的PRS配置；或者PRS配置集合中的PRS配置作为给终端设备预配置的PRS配置；或者PRS配置集合中的PRS配置既作为所述终端按需请求的PRS配置，又作为给终端设备预配置的PRS配置。
由于PRS配置集合的用途可以只包括上述3种，所述可以设置用途指示只占用2比特，即可实现对上述3种用途的指示。
而若通过一条信令单独指示PRS配置集合中的PRS配置作为终端按需请求的PRS配置，这条信令需要指示整个PRS配置集合，所需占用的资源大于2比特。
而若通过一条信令单独指示PRS配置集合中的PRS配置作为给终端设备预配置的PRS配置，这条信令至少要能够指示PRS配置集合中的每个PRS配置，所以占用的资源也大于2比特。
因此，本实施例在通过显示方式指示PRS配置集合的用途的情况下，相对于通过信令既携带PRS配置集合作为预配置的PRS配置发送给终端，又携带PRS配置集合作为按需请求的PRS配置发送给终端，所需占用资源相对较少，有利于节约信令资源。
以隐式方式为例，网络侧设备在将PRS配置集合发送给终端后，若没有发送用途指示，则默认PRS配置集合作为终端按需请求的PRS配置，若发送了用途指示，则默认是指示PRS配置集合中的一个或多个PRS配置给终端作为给终端预配置的PRS配置，无论是不发送用途指示，还是发送用途指示，相对于通过信令既携带PRS配置集合作为预配置的PRS配置发送给终端，又携带PRS配置集合作为按需请求的PRS配置发送给终端，所需占用资源都是相对较少的，因此有利于节约信令资源。
需要说明的是，在通过隐式方式指示的情况下，若没有发送用途指示，也可以是默认PRS配置集合中的PRS配置作为给终端预配置的PRS配置。而没有发送用途指示具体是默认指示哪种用途，可以在基站与终端通信协议中约定。
在一个实施例中，所述向所述终端指示所述PRS配置集合的用途包括：
向所述终端指示所述PRS配置集合中的PRS配置作为所述终端按需请求的PRS配置，且所述PRS配置集合中的PRS配置作为给所述终端设备预配置的PRS配置；
或者向所述终端指示所述PRS配置集合中的PRS配置作为所述终端按需请求的PRS配置；
或者向所述终端指示所述PRS配置集合中的PRS配置作为给所述终端预配置的PRS配置。
也即网络侧设备指示PRS配置集合的用途，可以指示上述3种用途之一。
需要说明的是，对于PRS配置集合的用途进行指示，可以是针对整个PRS配置集合进行指示，也即指示PRS配置集合中全部PRS配置的用途；也可以是针对PRS配置集合中的部分PRS配置进行指示，也即指示PRS配置集合中一个或多个PRS配置的用途。
网络侧设备可以指示PRS配置集合中的PRS配置仅作为终端按需请求的PRS配置。在这种情况下，终端可以在PRS配置集合中选择需要请求的PRS配置，并生成按需PRS请求发送给网络侧设备，以请求所选择的PRS配置。网络侧设备接收到终端的请求后，可以向所述终端发送所述终端请求的PRS配置，例如可以指示终端允许使用所选择的PRS配置，例如可以将终端所选择的PRS配置对应的标识发送给终端，例如可以将终端所选择的PRS配置发送给终端。
网络侧设备可以指示PRS配置集合中的PRS配置仅作为给终端预配置的PRS配置。在这种情况下，终端在定位过程中可以直接使用预配置的PRS配置来接收下行PRS。进一步地，终端不能向所述网络侧设备发送按需PRS请求，或者终端可以向网络侧设备发送按需PRS请求，但是按需PRS请求所请求的PRS配置，不包含所述PRS配置集合中的PRS配置和/或PRS配置标识，以免网络侧设备不能支持所请求的PRS配置和/或无法识别终端所请求的PRS配置标识。
网络侧设备可以指示PRS配置集合中的PRS配置既作为终端按需请求的PRS配置，指示PRS配置集合中的PRS配置又作为给终端预配置的PRS配置。在这种情况下，终端一方面可以根据网络侧设备的指示，将PRS配置集合中的一个或多个PRS配置作为预配置的PRS配置，另一方面，还可以根据PRS配置集合向网络侧设备发送按需PRS请求，例如在PRS配置集合中选择PRS配置，并向网络侧设备发送按需PRS请求，以请求选择的PRS配置。例如在预配置的PRS配置不满足终端需要的情况下，终端可以在PRS配置集合中，在预配置的PRS配置以外的PRS配置中选择满足终端需要的PRS配置，并向网络侧设备发送按需PRS请求，以请求选择的PRS配置。
另外，在指示PRS配置集合中的多个PRS配置作为预配置的PRS配置，且PRS配置集合中的PRS配置作为按需请求的PRS配置的情况下，网络侧设备可以在后续定位过程中，向终端发送定位请求信息时，通过定位请求信息在多个PRS配置中指示一个PRS配置作为供终端使用的PRS配置。在这种情况下，终端可以确定定位请求信息所指示的PRS配置是否满足需要(例如定位需要)，若不满足需要，可以在PRS配置集合中，在定位请求信息所指示的PRS配置以外的PRS配置中选择满足终端需要的PRS配置，并向网络侧设备发送按需PRS请求，以请求选择的PRS配置。
在一个实施例中，所述向所述终端指示所述PRS配置集合中的PRS配置作为给所述终端预配置的PRS配置包括：
向所述终端指示所述PRS配置集合中的多个PRS配置作为给所述终端预配置 的PRS配置；
或者所述向所述终端指示所述PRS配置集合中的PRS配置作为所述终端按需请求的PRS配置，且所述PRS配置集合中的PRS配置作为给所述终端设备预配置的PRS配置包括：
向所述终端指示所述PRS配置集合中的多个PRS配置作为给所述终端预配置的PRS配置，且所述PRS配置集合对应的PRS配置作为按需请求的PRS配置。
在一个实施例中，网络侧设备在向终端指示所述PRS配置集合中的多个PRS配置作为给终端预配置的PRS配置时，可以指示PRS配置集合中的所有PRS配置作为给终端预配置的PRS配置，在这种情况下，通过1个比特即可进行指示；也可以指示PRS配置集合中的一个或多个PRS配置作为给终端预配置的PRS配置，在这种情况下，需要通过多个比特进行指示。
在一个实施例中，在网络侧设备指示PRS配置集合中的PRS配置仅作为给终端预配置的PRS配置的情况下，网络侧设备可以指示PRS配置集合中的多个PRS配置作为给终端预配置的PRS配置。
在一个实施例中，在网络侧设备指示PRS配置集合中的PRS配置既作为终端按需请求的PRS配置，又作为给终端预配置的PRS配置的情况下，网络侧设备可以指示PRS配置集合中的多个PRS配置作为给终端预配置的PRS配置。
在一个实施例中，在网络侧设备指示PRS配置集合中的多个PRS配置作为给终端预配置的PRS配置时，终端在定位过程中当需要使用预配置的PRS配置时，只能使用其中的一个PRS配置，进而在选择的这个PRS配置对应的时频资源上接收下行PRS。
以下对终端如何从多个PRS配置中选择一个PRS配置当做预配置的PRS配置使用进行示例性说明。
图2是根据本公开的实施例示出的另一种用途指示方法的示意流程图。如图2所示，所述方法还包括：
在步骤S201中，向所述终端发送定位请求信息，其中，所述定位请求信息中携带有指示信息，所述指示信息用于指示所述多个PRS配置中的第一目标PRS配置作为PRS配置。
在一个实施例中，在网络侧设备指示PRS配置集合中的多个PRS配置作为给终端预配置的PRS配置时，但终端在定位过程中只会按照一个PRS配置接收下行PRS。
因此，网络侧设备在后续需要对终端进行定位，向终端发送定位请求信息时，可以在定位请求信息中携带有指示信息，通过指示信息指示多个PRS配置中的第一目标PRS配置作为PRS配置，从而使得终端只需根据这一个第一目标PRS配置接收下行PRS即可。
图3是根据本公开的实施例示出的又一种用途指示方法的示意流程图。如图3所示，所述向所述终端指示所述PRS配置集合中的PRS配置作为所述终端按需请求的PRS配置，且所述PRS配置集合中的PRS配置作为给所述终端设备预配置的PRS配置包括：
在步骤S301中，向所述终端指示所述PRS配置集合中的一个或多个PRS配置作为给所述终端预配置的PRS配置，且所述PRS配置集合对应的PRS配置作为按需请求的PRS配置。
在一个实施例中，在网络侧设备指示PRS配置集合中的PRS配置既作为终端按需请求的PRS配置，又作为给终端预配置的PRS配置的情况下，网络侧设备可以指示PRS配置集合中的一个或多个PRS配置作为给终端预配置的PRS配置，使得终端可以仅基于这一个PRS配置接收下行PRS。
图4是根据本公开的实施例示出的又一种用途指示方法的示意流程图。如图4所示，所述方法还包括：
在步骤S401中，接收所述终端发送的PRS配置请求；
在步骤S401中，向所述终端发送所述终端请求的PRS配置。
在一个实施例中，在网络侧设备指示PRS配置集合中的一个或多个PRS配置作为给终端预配置的PRS配置时，这一个或多个预配置的PRS配置，可能不满足终端定位的需求，例如终端需要更高精度的定位需求，则需要PRS配置的带宽更大，周期更小，而预配置的PRS配置带宽相对较小，和/或周期相对较大。
由于网络侧设备还指示了PRS配置集合中的PRS配置也可以作为终端按需请求的PRS配置，因此终端可以根据需要在PRS配置集合中选择预配置的PRS配置以外的PRS配置，并向网络侧设备发送请求，以请求所选择的PRS配置。进而网络侧设备可以向终端发送终端请求的PRS配置，例如可以指示终端允许使用所选择的PRS 配置，例如可以将终端所选择的PRS配置对应的标识发送给终端，例如可以将终端所选择的PRS配置发送给终端。据此，可以确保终端根据满足定位需求的PRS配置来接收下行PRS，确保顺利地接收到PRS。
在一个实施例中，所述方法还包括：确定为所述终端提供的PRS集合的用途；
所述向所述终端指示所述PRS配置集合的用途包括：
在为所述终端提供的PRS集合既作为按需请求的PRS，又作为预配置给所述终端的PRS时，指向所述终端指示所述PRS配置集合中的PRS配置作为所述终端按需请求的PRS配置，且所述PRS配置集合中的PRS配置作为给所述终端设备预配置的PRS配置；
在为所述终端提供的PRS集合仅作为按需PRS时，向所述终端指示所述PRS配置集合中的PRS配置作为所述终端按需请求的PRS配置；
在为所述终端提供的PRS集合仅作为预配置给所述终端的PRS时，向所述终端指示所述PRS配置集合中的PRS配置作为给所述终端预配置的PRS配置。
在一个实施例中，网络侧设备为终端提供的PRS集合可以具有指定用途，例如为终端提供的PRS集合仅作为按需请求的PRS，那么PRS配置也就只能作为按需请求的PRS配置，从而向终端指示PRS配置集合中的PRS配置作为终端按需请求的PRS配置；例如为终端提供的PRS集合仅作为预配置给终端的PRS时，那么PRS配置也就只能作为给终端预配置的PRS配置，从而向终端指示PRS配置集合中的PRS配置作为给终端预配置的PRS配置；例如为终端提供的PRS集合既作为按需请求的PRS，又作为预配置给终端的PRS时，那么PRS配置既能作为给终端预配置的PRS配置，又能作为按需请求的PRS配置，因此可以向终端指示PRS配置集合中的PRS配置作为终端按需请求的PRS配置，且PRS配置集合中的PRS配置作为给终端设备预配置的PRS配置。
其中，网络侧设备可以根据网络的能力和定位的需求，确定为终端提供的PRS集合的指定用途。例如在需要定位的时延相对较低时，为终端提供的PRS集合可以作为预配置给终端的PRS；例如在网络的能力可以支持按需请求PRS时，为终端提供的PRS集合可以作为按需请求的PRS；例如在既需要定位的时延相对较低，网络的能力可以支持按需请求PRS时，为终端提供的PRS集合既可以作为预配置给终端的PRS，又可以作为按需请求的PRS。
在一个实施例中，所述网络侧设备包括核心网，用于向所述终端指示所述PRS配置集合的用途的指示信息，携带在所述核心网向所述终端发送的LTE(Long Term Evolution，长期演进)定位协议消息(LPP，LTE Positioning Protocol)中。
在网络侧设备为核心网的情况下，核心网(例如核心网中的定位管理功能LMF)可以将指示述PRS配置集合的用途的指示信息携带在发送至(由基站透传)终端的LTE定位协议消息中，例如可以在对终端进行定位之前就发送给终端，例如指示信息可以携带在LPP提供辅助数据(LPP provide assistance data)中，可以连带PRS配置以外的定位辅助信息一并发送给终端。
在一个实施例中，所述网络侧设备包括基站，用于向所述终端指示所述PRS配置集合的用途的指示信息，携带在所述基站广播的定位系统消息中。
在网络侧设备为基站的情况下，基站可以将指示述PRS配置集合的用途的指示信息携带在广播的定位系统消息发送至终端，例如可以定义新的定位系统消息类型来包含所述PRS集合，例如新定义的类型为posSibType6-4。
需要说明的是，在这种情况下，PRS配置的源头可以是核心网，也即核心网先将PRS配置作为定位辅助信息发送给基站，基站再向终端广播携带定位辅助信息的定位系统消息。
图5是根据本公开的实施例示出的一种用途确定方法的示意流程图。本实施例所示的用途确定方法可以由终端备执行，所述终端可以作为用户设备与网络侧设备通信，所述网络侧设备包括但不限于基站、核心网，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图5所示，所述用途确定方法可以包括以下步骤：
在步骤S501中，接收网络侧设备发送的定位参考信号PRS配置集合；
在步骤S502中，根据所述网络侧设备的指示确定所述PRS配置集合的用途。
在一个实施例中，所述网络侧设备既可以为终端预配置定位辅助信息，又可以为终端配置按需请求的PRS配置，其中，定位辅助信息可以包括PRS配置，终端可以根据PRS配置接收PRS，进而根据接收到的PRS进行定位过程。
在这种情况下，网络侧设备如果通过信令既携带PRS配置作为预配置的PRS配置发送给终端，又携带PRS配置集合作为按需请求的PRS配置发送给终端，将会占 用较多的信令资源，导致信令开销较大。
根据本公开的实施例，网络侧设备只需通过一条信令携带PRS配置集合发送给终端，并向终端指示PRS配置集合的用途，而无需通过信令既携带预配置的PRS配置，又携带按需请求的PRS配置，有利于节约信令资源。
在一个实施例中，网络侧设备可以通过显式和/或隐式的方式向所述终端指示所述PRS配置集合的用途。
以显式方式为例，网络侧设备可以向终端发送用途指示，以指示PRS配置集合的用途。其中，PRS配置集合的用途包括3种，也即PRS配置集合中的PRS配置作为终端按需请求的PRS配置；或者PRS配置集合中的PRS配置作为给终端设备预配置的PRS配置；或者PRS配置集合中的PRS配置既作为所述终端按需请求的PRS配置，又作为给终端设备预配置的PRS配置。
由于PRS配置集合的用途可以只包括上述3种，所述可以设置用途指示只占用2比特，即可实现对上述3种用途的指示。
而若通过一条信令单独指示PRS配置集合中的PRS配置作为终端按需请求的PRS配置，这条信令需要指示整个PRS配置集合，所需占用的资源大于2比特。
而若通过一条信令单独指示PRS配置集合中的PRS配置作为给终端设备预配置的PRS配置，这条信令至少要能够指示PRS配置集合中的每个PRS配置，所以占用的资源也大于2比特。
因此，本实施例在通过显示方式指示PRS配置集合的用途的情况下，相对于通过信令既携带PRS配置集合作为预配置的PRS配置发送给终端，又携带PRS配置集合作为按需请求的PRS配置发送给终端，所需占用资源相对较少，有利于节约信令资源。
以隐式方式为例，网络侧设备在将PRS配置集合发送给终端后，若没有发送用途指示，则默认PRS配置集合作为终端按需请求的PRS配置，若发送了用途指示，则默认是指示PRS配置集合中的一个或多个PRS配置给终端作为给终端预配置的PRS配置，无论是不发送用途指示，还是发送用途指示，相对于通过信令既携带PRS配置集合作为预配置的PRS配置发送给终端，又携带PRS配置集合作为按需请求的PRS配置发送给终端，所需占用资源都是相对较少的，因此有利于节约信令资源。
需要说明的是，在通过隐式方式指示的情况下，若没有发送用途指示，也可以 是默认PRS配置集合中的PRS配置作为给终端预配置的PRS配置。而没有发送用途指示具体是默认指示哪种用途，可以在基站与终端通信协议中约定。
在一个实施例中，所述根据所述网络侧设备的指示确定所述PRS配置集合的用途包括：
根据所述网络侧设备的指示确定所述PRS配置集合中的PRS配置作为所述终端按需请求的PRS配置，且所述PRS配置集合中的PRS配置作为给所述终端设备预配置的PRS配置；
或者根据所述网络侧设备的指示确定所述PRS配置集合中的PRS配置作为所述终端按需请求的PRS配置；
或者根据所述网络侧设备的指示确定所述PRS配置集合中的PRS配置作为给所述终端预配置的PRS配置。
需要说明的是，网络侧对于PRS配置集合的用途进行指示，可以是针对整个PRS配置集合进行指示，也即指示PRS配置集合中全部PRS配置的用途；也可以是针对PRS配置集合中的部分PRS配置进行指示，也即指示PRS配置集合中一个或多个PRS配置的用途。
网络侧设备可以指示PRS配置集合中的PRS配置仅作为终端按需请求的PRS配置。在这种情况下，终端可以在PRS配置集合中选择需要请求的PRS配置，并生成按需PRS请求发送给网络侧设备，以请求所选择的PRS配置。网络侧设备接收到终端的请求后，可以向所述终端发送所述终端请求的PRS配置，例如可以指示终端允许使用所选择的PRS配置，例如可以将终端所选择的PRS配置对应的标识发送给终端，例如可以将终端所选择的PRS配置发送给终端。
网络侧设备可以指示PRS配置集合中的PRS配置仅作为给终端预配置的PRS配置。在这种情况下，终端在定位过程中可以直接使用预配置的PRS配置来接收下行PRS。进一步地，终端不能向所述网络侧设备发送按需PRS请求，或者终端可以向网络侧设备发送按需PRS请求，但是按需PRS请求所请求的PRS配置，不包含所述PRS配置集合中的PRS配置和/或PRS配置标识，以免网络侧设备不能支持所请求的PRS配置和/或无法识别终端所请求的PRS配置标识。
网络侧设备可以指示PRS配置集合中的PRS配置既作为终端按需请求的PRS配置，指示PRS配置集合中的PRS配置又作为给终端预配置的PRS配置。在这种情 况下，终端一方面可以根据网络侧设备的指示，将PRS配置集合中的一个或多个PRS配置作为预配置的PRS配置，另一方面，还可以根据PRS配置集合向网络侧设备发送按需PRS请求，例如在PRS配置集合中选择PRS配置，并向网络侧设备发送按需PRS请求，以请求选择的PRS配置。例如在预配置的PRS配置不满足终端需要的情况下，终端可以在PRS配置集合中，在预配置的PRS配置以外的PRS配置中选择满足终端需要的PRS配置，并向网络侧设备发送按需PRS请求，以请求选择的PRS配置。
另外，在指示PRS配置集合中的多个PRS配置作为预配置的PRS配置，且PRS配置集合中的PRS配置作为按需请求的PRS配置的情况下，网络侧设备可以在后续定位过程中，向终端发送定位请求信息时，通过定位请求信息在多个PRS配置中指示一个PRS配置作为供终端使用的PRS配置。在这种情况下，终端可以确定定位请求信息所指示的PRS配置是否满足需要(例如定位需要)，若不满足需要，可以在PRS配置集合中，在定位请求信息所指示的PRS配置以外的PRS配置中选择满足终端需要的PRS配置，并向网络侧设备发送按需PRS请求，以请求选择的PRS配置。
在一个实施例中，所述根据所述网络侧设备的指示确定所述PRS配置集合中的PRS配置作为所述终端按需请求的PRS配置包括：
根据所述网络侧设备的指示确定所述PRS配置集合中的多个PRS配置作为给所述终端预配置的PRS配置；
或者所述根据所述网络侧设备的指示确定所述PRS配置集合中的PRS配置作为所述终端按需请求的PRS配置，且所述PRS配置集合中的PRS配置作为给所述终端设备预配置的PRS配置包括：
根据所述网络侧设备的指示确定所述PRS配置集合中的多个PRS配置作为给所述终端预配置的PRS配置，且所述PRS配置集合对应的PRS配置作为按需请求的PRS配置。
在一个实施例中，网络侧设备在向终端指示所述PRS配置集合中的多个PRS配置作为给终端预配置的PRS配置时，可以指示PRS配置集合中的所有PRS配置作为给终端预配置的PRS配置，在这种情况下，通过1个比特即可进行指示；也可以指示PRS配置集合中的一个或多个PRS配置作为给终端预配置的PRS配置，在这种情况下，需要通过多个比特进行指示。
在一个实施例中，在网络侧设备指示PRS配置集合中的PRS配置仅作为给终 端预配置的PRS配置的情况下，网络侧设备可以指示PRS配置集合中的多个PRS配置作为给终端预配置的PRS配置。
在一个实施例中，在网络侧设备指示PRS配置集合中的PRS配置既作为终端按需请求的PRS配置，又作为给终端预配置的PRS配置的情况下，网络侧设备可以指示PRS配置集合中的多个PRS配置作为给终端预配置的PRS配置。
在一个实施例中，在网络侧设备指示PRS配置集合中的多个PRS配置作为给终端预配置的PRS配置时，终端在定位过程中，当需要使用预配置的PRS配置时，只能使用其中的一个PRS配置，进而在选择的这个PRS配置对应的时频资源上接收下行PRS。
以下对终端如何从多个PRS配置中选择一个PRS配置当做预配置的PRS配置使用进行示例性说明。
图6是根据本公开的实施例示出的另一种用途确定方法的示意流程图。如图6所示，所述方法还包括：
在步骤S601中，接收所述网络侧设备发送的定位请求信息；
在步骤S602中，根据所述定位请求信息中携带的指示信息，在所述多个PRS配置中确定第一目标PRS配置作为PRS配置。
在一个实施例中，在网络侧设备指示PRS配置集合中的多个PRS配置作为给终端预配置的PRS配置时，但终端在定位过程中只会按照一个PRS配置接收下行PRS。
因此，网络侧设备在后续需要对终端进行定位，向终端发送定位请求信息时，可以在定位请求信息中携带有指示信息，通过指示信息指示多个PRS配置中的第一目标PRS配置作为PRS配置，终可以根据定位请求信息中携带的指示信息，在多个PRS配置中确定第一目标PRS配置作为PRS配置，进而只需根据这一个第一目标PRS配置接收下行PRS即可。
图7是根据本公开的实施例示出的又一种用途确定方法的示意流程图。如图7所示，所述根据所述网络侧设备的指示确定所述PRS配置集合中的PRS配置作为所述终端按需请求的PRS配置，且所述PRS配置集合中的PRS配置作为给所述终端设备预配置的PRS配置包括：
在步骤S701中，根据所述网络侧设备的指示确定所述PRS配置集合中的一个 或多个PRS配置作为预配置的PRS配置，且所述PRS配置集合对应的PRS配置作为按需请求的PRS配置。
在一个实施例中，在网络侧设备指示PRS配置集合中的PRS配置既作为终端按需请求的PRS配置，又作为给终端预配置的PRS配置的情况下，网络侧设备可以指示PRS配置集合中的一个或多个PRS配置作为给终端预配置的PRS配置，使得终端可以仅基于这一个或多个PRS配置接收下行PRS。
图8是根据本公开的实施例示出的又一种用途确定方法的示意流程图。如图8所示，所述方法还包括：
在步骤S801中，在所述预配置的PRS配置不满足需求的情况下，向所述网络侧设备发送PRS配置请求，用于请求所述PRS配置集合中所述预配置的PRS配置以外的PRS配置。
在一个实施例中，在网络侧设备指示PRS配置集合中的一个或多个PRS配置作为给终端预配置的PRS配置时，这个预配置的PRS配置，可能不满足终端定位需求，例如终端需要更高精度的定位需求，则需要PRS配置的带宽更大，周期更小，而预配置的PRS配置带宽相对较小，和/或周期相对较大。
由于网络侧设备还指示了PRS配置集合中的PRS配置也可以作为终端按需请求的PRS配置，因此终端可以根据需要在PRS配置集合中选择预配置的PRS配置以外的PRS配置，并向网络侧设备发送请求，以请求所选择的PRS配置。进而网络侧设备可以向终端发送终端请求的PRS配置，例如可以指示终端允许使用所选择的PRS配置，例如可以将终端所选择的PRS配置对应的标识发送给终端，例如可以将终端所选择的PRS配置发送给终端。据此，可以确保终端根据满足定位需求的PRS配置来接收下行PRS，确保顺利地接收到PRS。
在一个实施例中，所述网络侧设备的指示所述PRS配置集合中的多个PRS配置作为预配置的PRS配置，所述方法还包括：
根据所述网络侧设备的定位请求信息，确定所述多个PRS配置中的第二目标PRS配置作为PRS配置；
在所述第二目标PRS配置不满足需求的情况下，向所述网络侧设备发送PRS配置请求，用于请求所述PRS配置集合中所述第二目标PRS配置以外的PRS配置。
在一个实施例中，在网络侧设备指示PRS配置集合中的第二目标PRS配置作 为PRS配置时，这个第二目标PRS配置，可能不满足终端定位需求，例如终端需要更高精度的定位需求，则需要PRS配置的带宽更大，周期更小，而第二目标PRS配置带宽相对较小，和/或周期相对较大。
由于网络侧设备还指示了PRS配置集合中的PRS配置也可以作为终端按需请求的PRS配置，因此终端可以根据需要在PRS配置集合中选择第二目标PRS配置以外的PRS配置，并向网络侧设备发送请求，以请求所选择的PRS配置。进而网络侧设备可以向终端发送终端请求的PRS配置，例如可以指示终端允许使用所选择的PRS配置，例如可以将终端所选择的PRS配置对应的标识发送给终端，例如可以将终端所选择的PRS配置发送给终端。据此，可以确保终端根据满足定位需求的PRS配置来接收下行PRS，确保顺利地接收到PRS。
在一个实施例中，所述网络侧设备包括核心网，用于向所述终端指示所述PRS配置集合的用途的指示信息，携带在所述核心网向所述终端发送的LTE定位协议消息中。
在网络侧设备为核心网的情况下，核心网(例如核心网中的定位管理功能LMF)可以将指示述PRS配置集合的用途的指示信息携带在发送至(由基站透传)终端的LTE定位协议消息中，例如可以在对终端进行定位之前就发送给终端，例如指示信息可以携带在LPP提供辅助数据中，可以连带PRS配置以外的定位辅助信息一并发送给终端。
在一个实施例中，所述网络侧设备包括基站，用于向所述终端指示所述PRS配置集合的用途的指示信息，携带在所述基站广播的定位系统消息中。
在网络侧设备为基站的情况下，基站可以将指示述PRS配置集合的用途的指示信息携带在广播的定位系统消息发送至终端，例如可以定义新的定位系统消息类型来包含所述PRS集合，例如新定义的类型为posSibType6-4。
需要说明的是，在这种情况下，PRS配置的源头可以是核心网，也即核心网先将PRS配置作为定位辅助信息发送给基站，基站再向终端广播携带定位辅助信息的定位系统消息。
