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能力信息发送方法的示意流程图。本实施例所示的能力信息发送方法可以由终端执行，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。所述终端可以与网络设备通信，所述网络设备包括但不限于4G、5G、6G等通信系统中的网络设备，例如基站、核心 网等。
如图1所示，所述能力信息发送方法可以包括以下步骤：
在步骤S101中，确定上行定位参考信号相关能力的能力信息；
在步骤S102中，将所述能力信息发送至网络设备。
在一个实施例中，终端可以确定自身上行定位参考信号相关能力的能力信息，进而将能力信息发送至网络设备。其中，所述上行定位参考信号包括但不限于探测参考信号SRS(Sounding Reference Signal)。
在一个实施例中，终端可以自发发送所述能力信息，例如周期性发送所述能力信息、在所述能力信息满足预设条件时发送所述能力信息。
在一个实施例中，终端可以根据网络设备的请求发送所述能力信息，例如网络设备可以先向终端发送获取所述能力信息的请求，终端在接收到所述请求后，向网络设备发送所述能力信息。
根据本公开的实施例，终端通过将上行定位参考信号相关能力的能力信息发送至网络设备，使得网络设备可以根据接收到的能力信息准确、全面地确定终端上行定位参考信号的相关能力，以便在需要根据上行定位参考信号进行相关业务时，网络设备可以根据需要对终端发送上行定位参考信号的操作进行适当的配置。
需要说明的是，所述能力信息对于网络设备而言是作为辅助信息，并不能决定网络设备后续对终端进行如何配置，也即网络设备具体对终端进行如何配置，仍然由网络设备自身决定，例如网络设备可以综合分析多个终端发送的辅助信息以及网络负载情况，决定是否根据接收到的能力信息为终端进行对应的配置。
在一个实施例中，所述能力信息携带在无线资源控制RRC(Radio Resource Control)消息或长期演进定位协议LPP(LTE Positioning Protocol)消息中。
例如在网络设备包括基站的情况下，终端可以通过RRC消息携带所述能力信息发送至基站；例如在网络设备包括核心网的情况下，网络设备可以通过LPP消息携带所述能力信息发送至核心网，所述核心网可以包括LMF(Location Management Function，定位管理功能)。
在一个实施例中，所述将所述能力信息发送至网络设备包括：
向所述网络设备发送所支持的定位算法信息，其中，在所述定位算法信息中携 带有所述能力信息。
终端在通过发送上行定位参考信号进行定位时，还需要上报所支持的定位算法信息，例如multi-RTT(多小区往返时间定位法(Multi-RTT,Multiplecell-Round Trip Time),UL-TDOA(上行到达时间差，Uplink Time Difference of Arrival)，UL-AoD(上行离开角，Angel of Departure),UL-carrier phase(上行载波相位)等算法。终端可以将所述能力信息携带在所支持的定位算法信息一起上报给网络设备。
在一个实施例中，所述能力信息包括以下至少之一：
支持关联有效区域的上行定位参考信号的能力，包括支持关联有效区域的上行定位参考信号和不支持关联有效区域的上行定位参考信号；
支持关联有效时间的上行定位参考信号的能力，包括支持关联有效时间的上行定位参考信号和不支持关联有效时间的上行定位参考信号；
支持调整关联有效区域的上行定位参考信号发送功率的能力，包括支持调整关联有效区域的上行定位参考信号发送功率和不支持调整关联有效区域的上行定位参考信号发送功率；
支持调整关联有效时间的上行定位参考信号发送功率的能力，包括支持调整关联有效时间的上行定位参考信号发送功率和不支持调整关联有效时间的上行定位参考信号发送功率；
支持根据第一信号的相关信息确定上行定位参考信号的定时提前量TA(Timing Advance)的能力，包括支持根据第一信号的相关信息确定上行定位参考信号的TA和不支持根据第一信号的相关信息确定上行定位参考信号的TA；
支持根据第二信号的相关信息确定所述TA的调整值的能力，包括支持根据第二信号的相关信息确定所述TA的调整值和不支持根据第二信号的相关信息确定所述TA的调整值；
支持向网络设备发送上行定位参考信号的能力，包括支持向网络设备发送上行定位参考信号和不支持向网络设备发送上行定位参考信号。
在一个实施例中，所述第一信号的相关信息和/或所述第二信号的相关信息包括以下至少之一：
路损pathloss；
强度，例如Reference Signal Receiving Power，参考信号接收功率；
信干噪比SINR(Signal to Interference plus Noise Ratio)。
在5G NR(New Radio，新空口)中引入了多种定位技术，可以实现对终端的定位，其中，在上行定位技术和上下行混合定位技术中，需要终端发送上行定位参考信号，因此，也就需要网络设备对终端发送上行定位参考信号进行配置，例如发送上行定位参考信号的定时提前量TA。
目前可以支持对非连接态(例如非激活inactive态度、空闲idle态)终端的定位，也即终端在处于非连接态时可以发送上行定位参考信号。还规定了当终端在非激活态进行小区重选，终端需要释放掉上行定位参考信号的配置(例如发送上行定位参考信号的TA)，这导致在终端进行小区重选时，由于没有上行定位参考信号的配置(例如TA)无效，而停止发送上行定位参考信号，从而导致在此期间无法根据上行定位参考信号对终端进行定位。
而在终端完成小区重选后，终端需要重新从网络设备获取上行定位参考信号的配置信息。在终端移动较快，频繁进行小区重选的场景中，会导致终端相对频繁地获取配置信息，对通信资源和终端电量造成较大消耗。
图2是根据本公开的实施例示出的另一种能力信息发送方法的示意流程图。如图2所示，所述方法还包括：
在步骤S201中，接收网络设备发送的区域指示信息；
在步骤S202中，根据所述区域指示信息确定有效区域；
在步骤S203中，当小区重选后所在的第一小区在所述有效区域内，使用接收所述区域指示信息时所在的小区提供的上行定位参考信号配置信息发送所述上行定位参考信号；
其中，所述支持关联有效区域的上行定位参考信号的能力包括：支持关联有效区域的上行定位参考信号。
在一个实施例中，支持关联有效区域的上行定位参考信号的能力，包括支持关联有效区域的上行定位参考信号和不支持关联有效区域的上行定位参考信号两种情况。
在终端支持关联有效区域的上行定位参考信号的情况下，网络设备根据能力信 息可以确定终端支持关联有效区域的上行定位参考信号，进而可以选择为终端配置有效区域，例如通过区域指示信息向终端指示有效区域。
终端根据区域指示信息可以确定有效区域，进而在进行小区重选后，可以判断所在的第一小区(例如重选到的小区)是否在有效区域内。若第一小区在有效区域内，可以继续使用接收所述区域指示信息时所在的小区提供的上行定位参考信号配置信息发送所述上行定位参考信号，从而不必重新从网络设备获取(例如向网络设备发送获取请求)上行定位参考信号的配置信息，有利益降低对通信资源和终端电量的消耗。
若第一小区不在有效区域内，终端可以重新从网络设备获取上行定位参考信号的配置信息。
在终端不支持关联有效区域的上行定位参考信号的情况下，网络设备根据能力信息可以确定终端不支持关联区域时间的上行定位参考信号，进而可以选择不为终端配置有效区域。在这种情况下，终端在进行小区重选后，可以释放上行定位参考信号的配置信息，还可以在重选到的小区重新从网络设备获取上行定位参考信号的配置信息。
图3是根据本公开的实施例示出的又一种能力信息发送方法的示意流程图。如图3所示，所述方法还包括：
在步骤S301中，接收网络设备发送的与有效区域中小区相关联的上行定位参考信号配置；
在步骤S302中，在所述有效区域内，根据所在小区关联的上行定位参考信号配置调整定位参考信号发送功率；
其中，所述支持调整关联有效区域的上行定位参考信号发送功率的能力包括：支持调整关联有效区域的上行定位参考信号发送功率。
在一个实施例中，支持调整关联有效区域的上行定位参考信号发送功率的能力，包括支持调整关联有效区域的上行定位参考信号发送功率和不支持调整关联有效区域的上行定位参考信号发送功率两种情况。
由于在有效区域内的不同位置，终端与网络设备之间的距离可以不同，如果终端发送上行定位参考信号的功率保持不变，那么在有效区域内距离网络设备较远的位置，网络设备接收到的上行定位参考信号的强度就会相对较小，从而影响接收效果。
在终端支持调整关联有效区域的上行定位参考信号发送功率的情况下，网络设备根据能力信息可以确定终端支持调整关联有效区域的上行定位参考信号发送功率，进而可以选择向终端发送与有效区域中小区相关联的上行定位参考信号配置。
其中，与有效区域中小区相关联的上行定位参考信号配置，包括但不限于上行定位参考信号的功率调整参数与小区之间的关联关系，例如对于到网络设备相对较远的小区，可以设置功率调整参数为正(也即终端可以提高上行定位参考信号的发送功率)，对于到网络设备相对较远的小区，可以设置功率调整参数为负(也即终端可以降低上行定位参考信号的发送功率)。
终端在进行小区重选后，可以判断所在的第一小区(例如重选到的小区)是否在有效区域内。若第一小区在有效区域内，可以进一步根据所在小区关联的上行定位参考信号配置调整定位参考信号发送功率，例如当确定所在小区到网络设备相对较远，可以提高上行定位参考信号的发送功率，当确定所在小区到网络设备相对较近，可以降低上行定位参考信号的发送功率。据此，使得上行定位参考信号的发送功率与终端所在小区相适应，有利于确保网络设备接收到上行定位参考信号的强度。
在终端不支持调整关联有效区域的上行定位参考信号发送功率的情况下，网络设备根据能力信息可以确定终端不支持调整关联有效区域的上行定位参考信号发送功率，进而可以选择不向终端发送与有效区域中小区相关联的上行定位参考信号配置。
需要说明的是，网络设备也可以只向终端区域指示信息供终端确定有效区域，但是不向终端发送与有效区域中小区相关联的上行定位参考信号配置，那么终端在有效区域内，可以不对定位参考信号发送功率进行调整，或者可以根据预先存储的调整参数调整定位参考信号发送功率。
图4是根据本公开的实施例示出的又一种能力信息发送方法的示意流程图。如图4所示，所述方法还包括：
在步骤S401中，接收网络设备发送的时间指示信息；
在步骤S402中，根据所述时间指示信息确定有效时间；
在步骤S403中，当小区重选后的时间在所述有效时间内，使用接收所述时间指示信息时所在的小区提供的上行定位参考信号配置信息发送所述上行定位参考信号；
其中，所述支持关联有效时间的上行定位参考信号的能力包括：支持关联有效 时间的上行定位参考信号。
在一个实施例中，支持关联有效时间的上行定位参考信号的能力，包括支持关联有效时间的上行定位参考信号和不支持关联有效时间的上行定位参考信号两种情况。
在终端支持关联有效时间的上行定位参考信号的情况下，网络设备根据能力信息可以确定终端支持关联有效时间的上行定位参考信号，进而可以选择为终端配置有效时间，例如通过时间指示信息向终端指示有效时间。
终端根据时间指示信息可以确定有效时间，进而在进行小区重选后，可以判断小区重选后的时间(也可以是其他时间，例如终端在需要发送上行定位参考信号的时间)是否在有效时间内。若第一小区在有效时间内，可以继续使用接收所述区域指示信息时所在的小区提供的上行定位参考信号配置信息发送所述上行定位参考信号，从而不必重新从网络设备获取(例如向网络设备发送获取请求)上行定位参考信号的配置信息，有利益降低对通信资源和终端电量的消耗。
若小区重选后的时间不在有效时间内，终端可以重新从网络设备获取上行定位参考信号的配置信息。
在终端不支持关联有效时间的上行定位参考信号的情况下，网络设备根据能力信息可以确定终端不支持关联有效时间的上行定位参考信号，进而可以选择不为终端配置有效时间。在这种情况下，终端在进行小区重选后，可以释放上行定位参考信号的配置信息，还可以在重选到的小区重新从网络设备获取上行定位参考信号的配置信息。
图5是根据本公开的实施例示出的又一种能力信息发送方法的示意流程图。如图5所示，所述方法还包括：
在步骤S501中，接收网络设备发送的与有效时间中时间段相关联的上行定位参考信号配置；
在步骤S502中，在所述有效时间内，根据所处的时间段关联的上行定位参考信号配置调整定位参考信号发送功率；
其中，所述支持调整关联有效时间的上行定位参考信号发送功率的能力包括：支持调整关联有效时间的上行定位参考信号发送功率。
在一个实施例中，支持调整关联有效时间的上行定位参考信号发送功率的能力，包括支持调整关联有效时间的上行定位参考信号发送功率和不支持调整关联有效时间的上行定位参考信号发送功率两种情况。
由于终端在一些情况下是状态(例如到网络设备的距离、运动速度等)是处于变动中的，在接收所述时间指示信息时所在的小区中接收到上行定位参考信号配置信息的第一时间之后，到第一时间越远的时刻，终端到网络设备的距离发生的变化可能就越大。
在终端与网络设备之间的距离改变的情况下，如果终端发送上行定位参考信号的功率保持不变，那么在距离网络设备较远的位置，网络设备接收到的上行定位参考信号的强度就会相对较小，从而影响接收效果。
在终端支持调整关联有效时间的上行定位参考信号发送功率的情况下，网络设备根据能力信息可以确定终端支持调整关联有效时间的上行定位参考信号发送功率，进而可以选择向终端发送与有效时间中时间段相关联的上行定位参考信号配置。
其中，与有效时间中时间段相关联的上行定位参考信号配置，包括但不限于上行定位参考信号的功率调整参数与时间段之间的关联关系，例如对于到第一时间相对较远的时间段，可以设置功率调整参数为正(也即终端可以提高上行定位参考信号的发送功率)，对于到第一时间相对较远的时间段，可以设置功率调整参数为负(也即终端可以降低上行定位参考信号的发送功率)。
终端在进行小区重选后，可以判断所在的时间段是否在有效时间内。若时间段在有效时间内，可以进一步所处的时间段关联的上行定位参考信号配置调整定位参考信号发送功率，例如当确定所在时间段到第一时间相对较远，可以提高上行定位参考信号的发送功率，当确定所在时间段到第一时间相对较近，可以降低上行定位参考信号的发送功率。据此，使得上行定位参考信号的发送功率与终端所在小区相适应，有利于确保网络设备接收到上行定位参考信号的强度。
在终端不支持调整关联有效时间的上行定位参考信号发送功率的情况下，网络设备根据能力信息可以确定终端不支持调整关联有效时间的上行定位参考信号发送功率，进而可以选择不向终端发送与有效时间中时间段相关联的上行定位参考信号配置。
需要说明的是，网络设备也可以只向终端时间指示信息供终端确定有效时间，但是不向终端发送与有效时间中时间段相关联的上行定位参考信号配置，那么终端在 有效时间内，可以不对定位参考信号发送功率进行调整，或者可以根据预先存储的调整参数调整定位参考信号发送功率。
图6是根据本公开的实施例示出的又一种能力信息发送方法的示意流程图。如图6所示，所述方法还包括：
在步骤S601中，根据所述第一信号的相关信息以及第一信号的相关信息与TA之间的第一关联关系确定TA；
在步骤S602中，根据确定的TA向网络设备发送上行定位参考信号；
其中，所述支持根据第一信号的相关信息确定上行定位参考信号的TA的能力包括：支持根据第一信号的相关信息确定上行定位参考信号的TA。
在一个实施例中，支持根据第一信号的相关信息确定上行定位参考信号的TA的能力，包括支持根据第一信号的相关信息确定上行定位参考信号的TA和不支持根据第一信号的相关信息确定上行定位参考信号的TA两种情况。
在终端支持根据第一信号的相关信息确定发送时的TA的情况下，网络设备根据能力信息可以确定终端支持根据第一信号的相关信息确定发送时的TA，进而可以选择为终端配置第一关联关系。
终端在进行小区重选后，可以根据所述第一信号的相关信息以及第一信号的相关信息与TA之间的第一关联关系确定TA，进而根据确定的TA向网络设备发送上行定位参考信号，从而避免在小区重选后TA无效的情况下，停止发送定位参考信号的问题。
在终端不支持根据第一信号的相关信息确定发送时的TA的情况下，网络设备根据能力信息可以确定终端不支持根据第一信号的相关信息确定发送时的TA，进而可以选择不为终端配置第一关联关系。
需要说明的是，网络设备也可以不为终端配置第一关联关系，那么终端在进行小区重选后，可以继续使用在接收到上行定位参考配置信息所在小区时所使用的TA来发送上行定位参考信号。
在一个实施例中，所述第一关联关系包括所述第一信息与TA之间非连续的关联关系，和/或所述第一信息与TA之间连续的关联关系。
在一个实施例中，第一信息与TA之间的第一关联关系可以是非连续的。
例如在第一信息包括参考信号的RSRP时，第一关联关系可以是多组第一信号的RSRP与TA之间的对应关系，例如{TA1,RSRP1},{TA2,RSRP2}，据此可以确定当接收到的参考信号的RSPR为RSRP1时，对应的TA为TA1，当接收到的参考信号的RSPR为RSRP2时，对应的TA为TA2。
其中，在第一信息包括第一信号的相关信息时，可以将第一信号的相关信息量化为3847个值，与3847个TA一一对应。
在这种情况下，可以通过表格存储第一关联关系，表格中包含第一信息与第一信息对应的TA，例如第一信息与TA之间可以是一一对应的。
在一个实施例中，第一信息与TA之间的第一关联关系可以是连续的，
例如第一关联关系可以是以第一信息为自变量，TA为因变量的函数。例如在在第一信息包括参考信号的RSRP时，第一关联关系可以为TA＝f(RSRP)，终端在接收到参考信号后，可以将参考信号的RSRP代入TA＝f(RSRP)，从而得出对应的TA。
需要说明的是，终端除了可以根据第一信号的相关信息以及第一信号的相关信息与TA之间的第一关联关系确定TA，还可以通过其他关联关系确定TA，例如根据小区的标识与TA之间的关联关系和重选后所在小区的标识确定TA。
图7是根据本公开的实施例示出的又一种能力信息发送方法的示意流程图。如图7所示，所述方法还包括：
在步骤S701中，根据所述第二信号的相关信息以及第二信号的相关信息与TA之间的第二关联关系确定TA的调整值；
在步骤S702中，根据所述调整值对确定的TA进行调整；
在步骤S703中，根据调整后的TA向网络设备发送上行定位参考信号；
其中，所述支持根据第二信号的相关信息确定所述TA的调整值的能力包括：支持根据第二信号的相关信息确定所述TA的调整值。
在一个实施例中，支持根据第二信号的相关信息确定所述TA的调整值的能力，包括支持根据第二信号的相关信息确定所述TA的调整值和不支持根据第二信号的相关信息确定所述TA的调整值两种情况。
在终端支持根据第二信号的相关信息确定所述TA的调整值的情况下，网络设备根据能力信息可以确定终端支持根据第二信号的相关信息确定所述TA的调整值， 进而可以选择为终端配置第二关联关系。
在根据小区的标识与TA之间的关联关系和重选后所在小区的标识确定TA的情况下，由于重选后所在小区是具有一定覆盖范围的，当终端距离小区中心越远，TA一般越大，当终端距离小区中心越近，TA一般越小，所以仅根据重选后所在小区的标识(并不限于标识，也可以是频点)确定的TA，与终端在重选后所在小区中所处位置对应的TA之间可能存在一定误差。
因此，终端在根据小区的标识与TA之间的关联关系和重选后所在小区的标识确定TA后，可以进一步在重选后所在小区获取第二信号，并根据第二关联关系确定获取到的第二信号的相关信息对应的TA调整值，然后根据TA调整值对确定的TA进行调整，最后可以根据调整后的TA向网络设备发送定位参考信号。
由于终端在重选后所在小区中所处的位置不同，第二信号的相关信息也有所不同，因此根据第二关联关系确定获取到的第二信号的相关信息对应的TA调整值，并根据TA调整值对确定的TA进行调整，有利于确保调整后的TA与终端在重选后所在小区所处位置对应的TA尽可能接近(例如相等)，进而使得终端可以使用适当的TA(也即调整后的TA)发送定位参考信号。
终端在进行小区重选后，可以根据所述第二信号的相关信息以及第二信号的相关信息与TA之间的第二关联关系确定TA，进而根据所述调整值对确定的TA进行调整，以及根据调整后的TA向网络设备发送上行定位参考信号，使得终端可以使用适当的TA发送定位参考信号。
在终端不支持根据第二信号的相关信息确定所述TA的调整值的情况下，网络设备根据能力信息可以确定终端不支持根据第二信号的相关信息确定所述TA的调整值，进而可以选择不为终端配置第二关联关系。
图8A是根据本公开的实施例示出的又一种能力信息发送方法的示意流程图。如图8A所示，所述方法还包括：
在步骤S801中，接收所述网络设备发送的上行定位参考信号的配置信息；
在步骤S802中，根据所述配置信息向网络设备上行定位参考信号；
其中，所述支持向网络设备发送上行定位参考信号的能力包括：支持向网络设备发送上行定位参考信号。
在一个实施例中，支持向网络设备发送上行定位参考信号的能力，包括支持向网络设备发送上行定位参考信号和不支持向网络设备发送上行定位参考信号两种情况。
在终端支持向网络设备发送上行定位参考信号的情况下，网络设备根据能力信息可以确定终端支持向网络设备发送上行定位参考信号，进而可以选择向终端发送上行定位参考信号的配置信息，从而终端可以根据接收到的配置信息向网络设备发送上行定位参考信号。

如图9所示，所述能力确定方法可以包括以下步骤：
在步骤S901中，接收终端发送的能力信息；
在步骤S902中，根据所述能力信息确定所述终端的上行定位参考信号相关能力。
在一个实施例中，终端可以确定自身上行定位参考信号相关能力的能力信息，进而将能力信息发送至网络设备。其中，所述上行定位参考信号包括但不限于探测参考信号SRS(Sounding Reference Signal)。
在一个实施例中，终端可以自发发送所述能力信息，例如周期性发送所述能力信息、在所述能力信息满足预设条件时发送所述能力信息。
在一个实施例中，终端可以根据网络设备的请求发送所述能力信息，例如网络设备可以先向终端发送获取所述能力信息的请求，终端在接收到所述请求后，向网络设备发送所述能力信息。
根据本公开的实施例，终端通过将上行定位参考信号相关能力的能力信息发送至网络设备，使得网络设备可以根据接收到的能力信息准确、全面地确定终端上行定位参考信号的相关能力，以便在需要根据上行定位参考信号进行相关业务时，网络设备可以根据需要对终端发送上行定位参考信号的操作进行适当的配置。
在一个实施例中，所述能力信息包括以下至少之一：

在一个实施例中，所述第一信号的相关信息和/或所述第二信号的相关信息包括以下至少之一：路损；强度；信干噪比。
在一个实施例中，所述能力信息携带在无线资源控制RRC消息或长期演进定位协议LPP消息中。
例如在网络设备包括基站的情况下，终端可以通过RRC消息携带所述能力信息发送至基站；例如在网络设备包括核心网的情况下，网络设备可以通过LPP消息携带所述能力信息发送至核心网，所述核心网可以包括LMF。
需要说明的是，所述能力信息对于网络设备而言是作为辅助信息，并不能决定网络设备后续对终端进行如何配置，也即网络设备具体对终端进行如何配置，仍然由网络设备自身决定，例如网络设备可以综合分析多个终端发送的辅助信息以及网络负载情况，决定是否根据接收到的能力信息为终端进行对应的配置。
以下通过几个实施例，在网络设备根据能力信息对终端做出相应配置的情况下进行示例性描述。
在一个实施例中，支持关联有效区域的上行定位参考信号的能力，包括支持关联有效区域的上行定位参考信号和不支持关联有效区域的上行定位参考信号两种情况。
在终端支持关联有效区域的上行定位参考信号的情况下，网络设备根据能力信息可以确定终端支持关联有效区域的上行定位参考信号，进而可以选择为终端配置有效区域，例如通过区域指示信息向终端指示有效区域。
终端根据区域指示信息可以确定有效区域，进而在进行小区重选后，可以判断所在的第一小区(例如重选到的小区)是否在有效区域内。若第一小区在有效区域内，可以继续使用接收所述区域指示信息时所在的小区提供的上行定位参考信号配置信息发送所述上行定位参考信号，从而不必重新从网络设备获取(例如向网络设备发送获取请求)上行定位参考信号的配置信息，有利益降低对通信资源和终端电量的消耗。
若第一小区不在有效区域内，终端可以重新从网络设备获取上行定位参考信号 的配置信息。
在终端不支持关联有效区域的上行定位参考信号的情况下，网络设备根据能力信息可以确定终端不支持关联区域时间的上行定位参考信号，进而可以选择不为终端配置有效区域。在这种情况下，终端在进行小区重选后，可以释放上行定位参考信号的配置信息，还可以在重选到的小区重新从网络设备获取上行定位参考信号的配置信息。
在一个实施例中，支持调整关联有效区域的上行定位参考信号发送功率的能力，包括支持调整关联有效区域的上行定位参考信号发送功率和不支持调整关联有效区域的上行定位参考信号发送功率两种情况。
由于在有效区域内的不同位置，终端与网络设备之间的距离可以不同，如果终端发送上行定位参考信号的功率保持不变，那么在有效区域内距离网络设备较远的位置，网络设备接收到的上行定位参考信号的强度就会相对较小，从而影响接收效果。
在终端支持调整关联有效区域的上行定位参考信号发送功率的情况下，网络设备根据能力信息可以确定终端支持调整关联有效区域的上行定位参考信号发送功率，进而可以选择向终端发送与有效区域中小区相关联的上行定位参考信号配置。
其中，与有效区域中小区相关联的上行定位参考信号配置，包括但不限于上行定位参考信号的功率调整参数与小区之间的关联关系，例如对于到网络设备相对较远的小区，可以设置功率调整参数为正(也即终端可以提高上行定位参考信号的发送功率)，对于到网络设备相对较远的小区，可以设置功率调整参数为负(也即终端可以降低上行定位参考信号的发送功率)。
终端在进行小区重选后，可以判断所在的第一小区(例如重选到的小区)是否在有效区域内。若第一小区在有效区域内，可以进一步根据所在小区关联的上行定位参考信号配置调整定位参考信号发送功率，例如当确定所在小区到网络设备相对较远，可以提高上行定位参考信号的发送功率，当确定所在小区到网络设备相对较近，可以降低上行定位参考信号的发送功率。据此，使得上行定位参考信号的发送功率与终端所在小区相适应，有利于确保网络设备接收到上行定位参考信号的强度。
在终端不支持调整关联有效区域的上行定位参考信号发送功率的情况下，网络设备根据能力信息可以确定终端不支持调整关联有效区域的上行定位参考信号发送功率，进而可以选择不向终端发送与有效区域中小区相关联的上行定位参考信号配置。
需要说明的是，网络设备也可以只向终端区域指示信息供终端确定有效区域，但是不向终端发送与有效区域中小区相关联的上行定位参考信号配置，那么终端在有效区域内，可以不对定位参考信号发送功率进行调整，或者可以根据预先存储的调整参数调整定位参考信号发送功率。
在一个实施例中，支持关联有效时间的上行定位参考信号的能力，包括支持关联有效时间的上行定位参考信号和不支持关联有效时间的上行定位参考信号两种情况。
在终端支持关联有效时间的上行定位参考信号的情况下，网络设备根据能力信息可以确定终端支持关联有效时间的上行定位参考信号，进而可以选择为终端配置有效时间，例如通过时间指示信息向终端指示有效时间。
终端根据时间指示信息可以确定有效时间，进而在进行小区重选后，可以判断小区重选后的时间(也可以是其他时间，例如终端在需要发送上行定位参考信号的时间)是否在有效时间内。若第一小区在有效时间内，可以继续使用接收所述区域指示信息时所在的小区提供的上行定位参考信号配置信息发送所述上行定位参考信号，从而不必重新从网络设备获取(例如向网络设备发送获取请求)上行定位参考信号的配置信息，有利益降低对通信资源和终端电量的消耗。
若小区重选后的时间不在有效时间内，终端可以重新从网络设备获取上行定位参考信号的配置信息。
在终端不支持关联有效时间的上行定位参考信号的情况下，网络设备根据能力信息可以确定终端不支持关联有效时间的上行定位参考信号，进而可以选择不为终端配置有效时间。在这种情况下，终端在进行小区重选后，可以释放上行定位参考信号的配置信息，还可以在重选到的小区重新从网络设备获取上行定位参考信号的配置信息。
在一个实施例中，支持调整关联有效时间的上行定位参考信号发送功率的能力，包括支持调整关联有效时间的上行定位参考信号发送功率和不支持调整关联有效时间的上行定位参考信号发送功率两种情况。
由于终端在一些情况下是状态(例如到网络设备的距离、运动速度等)是处于变动中的，在接收所述时间指示信息时所在的小区中接收到上行定位参考信号配置信息的第一时间之后，到第一时间越远的时刻，终端到网络设备的距离发生的变化可能 就越大。
在终端与网络设备之间的距离改变的情况下，如果终端发送上行定位参考信号的功率保持不变，那么在距离网络设备较远的位置，网络设备接收到的上行定位参考信号的强度就会相对较小，从而影响接收效果。
在终端支持调整关联有效时间的上行定位参考信号发送功率的情况下，网络设备根据能力信息可以确定终端支持调整关联有效时间的上行定位参考信号发送功率，进而可以选择向终端发送与有效时间中时间段相关联的上行定位参考信号配置。
其中，与有效时间中时间段相关联的上行定位参考信号配置，包括但不限于上行定位参考信号的功率调整参数与时间段之间的关联关系，例如对于到第一时间相对较远的时间段，可以设置功率调整参数为正(也即终端可以提高上行定位参考信号的发送功率)，对于到第一时间相对较远的时间段，可以设置功率调整参数为负(也即终端可以降低上行定位参考信号的发送功率)。
终端在进行小区重选后，可以判断所在的时间段是否在有效时间内。若时间段在有效时间内，可以进一步所处的时间段关联的上行定位参考信号配置调整定位参考信号发送功率，例如当确定所在时间段到第一时间相对较远，可以提高上行定位参考信号的发送功率，当确定所在时间段到第一时间相对较近，可以降低上行定位参考信号的发送功率。据此，使得上行定位参考信号的发送功率与终端所在小区相适应，有利于确保网络设备接收到上行定位参考信号的强度。
在终端不支持调整关联有效时间的上行定位参考信号发送功率的情况下，网络设备根据能力信息可以确定终端不支持调整关联有效时间的上行定位参考信号发送功率，进而可以选择不向终端发送与有效时间中时间段相关联的上行定位参考信号配置。
在一个实施例中，支持根据第一信号的相关信息确定上行定位参考信号的TA的能力，包括支持根据第一信号的相关信息确定上行定位参考信号的TA和不支持根据第一信号的相关信息确定上行定位参考信号的TA两种情况。
在终端支持根据第一信号的相关信息确定发送时的TA的情况下，网络设备根据能力信息可以确定终端支持根据第一信号的相关信息确定发送时的TA，进而可以选择为终端配置第一关联关系。
终端在进行小区重选后，可以根据所述第一信号的相关信息以及第一信号的相关信息与TA之间的第一关联关系确定TA，进而根据确定的TA向网络设备发送上行 定位参考信号，从而避免在小区重选后TA无效的情况下，停止发送定位参考信号的问题。
在终端不支持根据第一信号的相关信息确定发送时的TA的情况下，网络设备根据能力信息可以确定终端不支持根据第一信号的相关信息确定发送时的TA，进而可以选择不为终端配置第一关联关系。
需要说明的是，网络设备也可以不为终端配置第一关联关系，那么终端在进行小区重选后，可以继续使用在接收到上行定位参考配置信息所在小区时所使用的TA来发送上行定位参考信号。
在一个实施例中，所述第一关联关系包括所述第一信息与TA之间非连续的关联关系，和/或所述第一信息与TA之间连续的关联关系。
在一个实施例中，第一信息与TA之间的第一关联关系可以是非连续的。
例如在第一信息包括参考信号的RSRP时，第一关联关系可以是多组第一信号的RSRP与TA之间的对应关系，例如{TA1,RSRP1},{TA2,RSRP2}，据此可以确定当接收到的参考信号的RSPR为RSRP1时，对应的TA为TA1，当接收到的参考信号的RSPR为RSRP2时，对应的TA为TA2。
其中，在第一信息包括第一信号的相关信息时，可以将第一信号的相关信息量化为3847个值，与3847个TA一一对应。
在这种情况下，可以通过表格存储第一关联关系，表格中包含第一信息与第一信息对应的TA，例如第一信息与TA之间可以是一一对应的。
在一个实施例中，第一信息与TA之间的第一关联关系可以是连续的，
例如第一关联关系可以是以第一信息为自变量，TA为因变量的函数。例如在在第一信息包括参考信号的RSRP时，第一关联关系可以为TA＝f(RSRP)，终端在接收到参考信号后，可以将参考信号的RSRP代入TA＝f(RSRP)，从而得出对应的TA。
需要说明的是，终端除了可以根据第一信号的相关信息以及第一信号的相关信息与TA之间的第一关联关系确定TA，还可以通过其他关联关系确定TA，例如根据小区的标识与TA之间的关联关系和重选后所在小区的标识确定TA。
在一个实施例中，支持根据第二信号的相关信息确定所述TA的调整值的能力，包括支持根据第二信号的相关信息确定所述TA的调整值和不支持根据第二信号的相 关信息确定所述TA的调整值两种情况。
在终端支持根据第二信号的相关信息确定所述TA的调整值的情况下，网络设备根据能力信息可以确定终端支持根据第二信号的相关信息确定所述TA的调整值，进而可以选择为终端配置第二关联关系。
在根据小区的标识与TA之间的关联关系和重选后所在小区的标识确定TA的情况下，由于重选后所在小区是具有一定覆盖范围的，当终端距离小区中心越远，TA一般越大，当终端距离小区中心越近，TA一般越小，所以仅根据重选后所在小区的标识(并不限于标识，也可以是频点)确定的TA，与终端在重选后所在小区中所处位置对应的TA之间可能存在一定误差。
因此，终端在根据小区的标识与TA之间的关联关系和重选后所在小区的标识确定TA后，可以进一步在重选后所在小区获取第二信号，并根据第二关联关系确定获取到的第二信号的相关信息对应的TA调整值，然后根据TA调整值对确定的TA进行调整，最后可以根据调整后的TA向网络设备发送定位参考信号。
由于终端在重选后所在小区中所处的位置不同，第二信号的相关信息也有所不同，因此根据第二关联关系确定获取到的第二信号的相关信息对应的TA调整值，并根据TA调整值对确定的TA进行调整，有利于确保调整后的TA与终端在重选后所在小区所处位置对应的TA尽可能接近(例如相等)，进而使得终端可以使用适当的TA(也即调整后的TA)发送定位参考信号。
终端在进行小区重选后，可以根据所述第二信号的相关信息以及第二信号的相关信息与TA之间的第二关联关系确定TA，进而根据所述调整值对确定的TA进行调整，以及根据调整后的TA向网络设备发送上行定位参考信号，使得终端可以使用适当的TA发送定位参考信号。
在终端不支持根据第二信号的相关信息确定所述TA的调整值的情况下，网络设备根据能力信息可以确定终端不支持根据第二信号的相关信息确定所述TA的调整值，进而可以选择不为终端配置第二关联关系。
在一个实施例中，支持向网络设备发送上行定位参考信号的能力，包括支持向网络设备发送上行定位参考信号和不支持向网络设备发送上行定位参考信号两种情况。
在终端支持向网络设备发送上行定位参考信号的情况下，网络设备根据能力信 息可以确定终端支持向网络设备发送上行定位参考信号，进而可以选择向终端发送上行定位参考信号的配置信息，从而终端可以根据接收到的配置信息向网络设备发送上行定位参考信号。
在终端不支持向网络设备发送上行定位参考信号的情况下，网络设备根据能力信息可以确定终端不支持向网络设备发送上行定位参考信号，进而可以选择不向终端发送上行定位参考信号的配置信息。
