背景技术
4G LTE(the 4th Generation mobile communication technology Long Term Evolution，***移动通信技术长期演进)和5G NR(New Radio，新空口)***中需要通过随机接入流程来完成上行同步。其中，随机接入流程中包括消息1(Message1，Msg1)(随机接入前导)、Msg2(随机接入响应)、Msg3(调度传输)和Msg4(竞争解决)的四类消息的发送与接收。基站在发送给UE(User Equipment，用户设备)的随机接入响应中会携带TA(Timing Advance，定时提前量)，以使UE据此调整其上行发射时间。如何加快终端的上行同步过程并且降低TA获取流程中的消息开销是亟待解决的问题。

具体实施方式
下文中将结合附图对本申请的实施例进行说明。
在一个示例性实施方式中，图1为本申请提供的一种定时提前量的确定方法的流程示意图。该方法适用于终端与基站建立上行同步的情况。该方法可以由本申请提供的定时提前量的确定装置执行，该定时提前量的确定装置可以由软件和/或硬件实现，并集成在通信终端中。
如图1所示，本申请提供的定时提前量的确定方法，包括：
S110、终端获得定时提前量TA列表信息，其中，所述TA列表信息由基站发送给所述终端或者默认配置存储于所述终端。
TA(Timing Advance，定时提前量)，一般用于UE上行传输，指为了将UE上行包在希望的时间到达基站，预估由于距离引起的射频传输时延，提前相应时间发出数据包。
TA列表信息，指的是包括至少一个TA值或者是指示至少一个TA值的信息，可以默认配置存储于终端中，也可以由基站在上行同步之前发送给终端，例如是在终端与基站的下行同步过程中基站将TA列表信息发送给终端。
TA列表信息指示至少一个TA列表，所述TA列表中包括至少一个TA值。当TA列表信息只指示一个TA列表时，根据TA列表信息就可唯一确定这个TA 列表。
本示例中涉及的TA列表，可以是真实存在的列表，也可以是不真实存在的虚拟列表。其中，一个或多个TA值即可构成虚拟TA列表。
TA列表信息包含两种含义：
一种是，当所述TA列表信息默认配置存储于所述终端时，预先定义的一个或多个TA列表，其中每个TA列表中包括至少一个TA列表，所述TA列表信息即为所述一个或多个TA列表的索引信息。根据TA列表信息即可确定一个或多个TA列表。预先定义的TA列表中会给出选择一个TA值所需满足的条件或者对应关系。
另一种是，当所述TA列表信息是由基站发送给所述终端时，基站直接配置至少一个TA值，可以称这至少一个TA值构成一个或多个TA列表(或者称这至少一个TA值构成一个或多个虚拟TA列表)，进而这一个或多个TA列表也可构成TA列表信息。其中，这至少一个TA值由基站通过信令发送给所述终端。
本实施例中，所述终端处于与基站失去上行同步的状态。终端可以处于以下至少一种状态：
RRC-IDLE(Radio Resource Control-IDLE，无线资源控制空闲)状态；非激活(Inactive)状态；RRC-CONNECTED(Radio Resource Control-CONNECTED，无线资源控制连接)状态，并且所述终端收到TA更新触发信息或者TA重配置信息；无线资源控制空闲RRC_IDLE状态，并且所述终端使用PUSCH(Physical Uplink Share Channel，物理上行共享信道)传输业务；随机接入过程中，并且所述终端发送的随机接入信息中至少包括随机接入前导(Preamble)信息和负载信息；SRS(Sounding Reference Signal，探测参考信号)自主传输。
在终端处于RRC_CONNECTED状态，并且所述终端收到TA更新触发信息或者TA重配置信息的情况下，TA更新触发信息或者TA重配置信息可以通过RRC(Radio Resource Control，无线资源控制)消息发送或者通过MAC CE(Medium Access Control Control Element，媒体接入控制层控制单元)发送。
S120、所述终端根据所述TA列表信息获得目标TA值。
目标TA值，指的是与终端对应的用于实现对该终端上行信道发送的定时提前量进行调整的TA值。终端基于预设的对应关系，可以根据所述TA列表信息获得目标TA值。
当TA列表信息只指示一个TA列表时，终端则直接根据这个TA列表获得目标TA值。当这个TA列表中包括至少两个TA值时，终端则在其中选取一个TA值作为目标TA值；当这个TA列表中只包括一个TA值时，终端则直接获取 这个TA值作为目标TA值。
S130、所述终端利用所述目标TA值调整上行信道发送的定时提前量。
所述终端获取目标TA值之后，将所述目标TA值作为其上行信道发送的定时提前量，也即所述终端基于所述目标TA值进行上行数据的传输。
本实施例提供的技术方案，将TA列表信息默认配置存储于终端中，或者设置TA列表信息在终端与基站进行上行同步之前由基站发送给所述终端，以使所述终端可以直接根据TA列表信息获取用于调整上行信道发送的定时提前量的目标TA值。该技术方案无需随机接入流程的支持，即可实现终端上行自适应的同步过程，以此加快了终端上行同步过程，也降低了用于上行同步的消息的资源开销。
在一示例中，当所述TA列表信息指示至少两个TA列表时，所述终端根据所述TA列表信息获得目标TA值，包括：
所述终端根据所述TA列表信息获得目标TA列表；所述终端从所述目标TA列表中获得目标TA值。
在TA列表信息指示多个TA列表的情况下，终端首先根据TA列表信息选取一个TA列表作为目标TA列表，然后在目标TA列表中选取一个TA值作为目标TA值。当选取的目标TA列表中只包括一个TA值时，从所述目标TA列表中获得目标TA值，即为将目标TA列表中包括的这个TA值作为目标TA值。
所述终端根据所述TA列表信息获得目标TA列表，可以是根据所述TA列表信息的指示获得目标TA列表，也可以是在所述TA列表信息中获得目标TA列表。
在一示例中，所述TA列表与以下至少之一存在对应关系：
至少一个测量信息，其中，所述测量信息是所述终端测量服务小区和/或邻区的参考信号或信道而得到的；至少一个SSB(SS/PBCH Block，同步信号块)索引；至少一个波束方向；至少一组CSI-RS(Channel-State Information Reference Signal，信道状态信息参考信号)；服务小区标识(Identifier，ID)；至少一个邻区ID；邻区的数量；所述终端的定位(Positioning)信息。
TA列表与某信息存在对应关系，指的是可以根据该信息以及TA列表信息找到终端需要使用的目标TA列表。
所述测量信息是所述终端测量服务小区和/或邻区的参考信号或信道而得到的，参考信号包括SSB、CSI-RS中的至少之一。
在一示例中，所述测量信息包括以下至少之一：
RSRP(Reference Signal Receiving Power，参考信号接收功率)；RSRQ(Reference Signal Receiving Quality，参考信号接收质量)；RSSI(Received Signal Strength Indication，接收的信号强度指示)。
在5G NR(New Radio，新空口)中，主同步信号(Primary Synchronization Signal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)和物理广播信道(Physical Broadcast Channel，PBCH)共同构成一个SSB。
所述终端根据所述TA列表信息获得目标TA列表，包括：所述终端根据所述对应关系以及所述TA列表信息获得目标TA列表。
以所述终端根据TA列表与测量信息的对应关系以及所述TA列表信息获得目标TA列表为例，所述终端根据所述对应关系以及所述TA列表信息获得目标TA列表，就是所述终端将与测量信息对应的TA列表作为目标TA列表。
在一示例中，当TA列表与“至少一个测量信息”存在对应关系时，所述终端可以根据TA列表与所述至少一个测量信息的对应关系以及所述TA列表信息获得目标TA列表。终端可以根据满足第一条件的测量信息的数量以及所述TA列表信息获得目标TA列表。其中，第一条件指的是测量信息值大于或者等于确定的门限值。每一种所述“满足第一条件的测量信息的数量”都对应了至少一个TA列表，进而，根据“满足第一条件的测量信息的数量”即可对应确定至少一个TA列表，并在所述至少一个TA列表中确定出所述目标TA列表。在每一种所述“满足第一条件的测量信息的数量”都只对应一个TA列表时，根据“满足第一条件的测量信息的数量”即可对应确定一个TA列表，这个TA列表即为目标TA列表。
在一示例中，当TA列表与“至少一个SSB”存在对应关系时，所述终端可以根据TA列表与所述至少一个SSB的对应关系以及所述TA列表信息获得目标TA列表。在确定终端接收的SSB之后，根据所述TA列表信息获取与所述SSB索引对应的TA列表作为目标TA列表。在本示例中，TA列表与2个SSB存在对应关系。假设基站配置了4个SSB，索引分别为SSB0、SSB1、SSB2和SSB3，定义SSB0和SSB1对应TA列表0，SSB2和SSB3对应TA列表1。当终端接收的SSB的索引为SSB1时，则TA列表0为目标TA列表，也即终端的目标TA值存在于TA列表0中；当终端接收的SSB的索引为SSB3时，则TA列表1为目标TA列表，也即终端的目标TA值存在于TA列表1中。
在一示例中，当TA列表与“至少一个波束方向”存在对应关系时，所述终端可以根据TA列表与所述至少一个波束方向的对应关系以及所述TA列表信息获得目标TA列表。在终端选择波束方向之后，根据所述TA列表信息获取与所述选择的波束方向对应的TA列表作为目标TA列表。在本示例中，TA列表与1个波束方向存在对应关系。假设基站配置了4个波束方向，索引分别为波束方 向0、波束方向1、波束方向2和波束方向3，定义波束方向0对应TA列表0，波束方向1对应TA列表1，波束方向2对应TA列表2，波束方向3对应TA列表3。当终端选择的波束方向为波束方向1时，则TA列表1为目标TA列表，也即终端的目标TA值存在于TA列表1中。本示例中，基站可以直接配置明确的波束方向，基站也可以通过配置SSB和/或CSI-RS来隐含指示波束方向，即一个SSB和/或CSI-RS对应一个波束方向。
在一示例中，当TA列表与“至少一组CSI-RS”存在对应关系时，所述终端可以根据TA列表与所述至少一组CSI-RS的对应关系以及所述TA列表信息获得目标TA列表。其中，所述CSI-RS是由基站配置的。所述CSI-RS是终端进行波束管理或者移动性测量时使用的参考信号。

所述“终端从基站配置的CSI-RS中选择至少一组CSI-RS”的原则包括以下至少之一：
基于所述CSI-RS测量得到的所述测量信息值大于或者等于确定的门限值；基于所述CSI-RS测量得到的所述测量信息值为最大值。
