一种信号的传输方法、终端、网络设备和存储介质

本申请要求于2020年03月05日提交的申请号为2020101486671，发明名称为“一种信号的传输方法、终端、网络设备和存储介质”的中国专利申请的优先权，其通过引用方式全部并入本文。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种信号的传输方法、终端、网络设备和存储介质。
背景技术
多点协作在无线通信系统中是一种重要的技术手段。通过多个分布式传输接收点进行分布式传输，可以改善小区边缘的覆盖，降低越区切换带来的时延和信令开销。例如在高铁场景下，为了避免终端UE(User Equipment，用户设备)进行频繁的小区切换，通常采用SFN(Single Frequency Network，单频网)的部署方式，简称为HST-SFN(High Speed Train-Single Frequency Network，高铁单频网)场景。在HST-SFN场景下，一个小区cell包含多个传输接收点(例如RRH(Remote Radio Head，射频拉远头))，信号从多个传输接收点同时发出。当列车运行到相邻两个传输接收点之间时，来自于两个RRH的信号其中一个为负的多普勒频移，另一个为正的多普勒频移，这样会产生多普勒谱。由于列车移动速度很快，多普勒频移的变化范围有可能很大，从而导致终端不能很好地进行下行信号的解调。
为了解决终端接收到的来自不同的RRH存在相反的多普勒频移的问题，一种方法是在每个RRH分别进行多普勒频移的预补偿，以消除UE接收到的下行信号的多普勒扩展。但现有技术中在多点传输时，UE只确定出一个下行频点，并基于该下行频点进行上行信号的传输。由于各个RRH的地理位置和/或接收波束方向的不同，上行信号到达各个RRH经历的多普勒频移是不同的。由于RRH并不知道UE基于什么样的下行频点进行上行信号的传输，因此，RRH无法估计出下行或上行经历的多普勒频移，从而无法有效地进行多 普勒频移的预补偿。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在HST-SFN场景下，多个传输接收点(transmission and reception point，TRP)(可以是一些RRH)通过光纤连接到同一个BBU(Base Band Unit，基带处理单元)，这多个TRP使用相同的小区ID。通过连接多个TRP的方式，扩大了小区的覆盖范围，从而降低了终端的小区切换频率。由于TRP通过光纤连接到BBU，因此，可以认为这些TRP之间是理想的回程(backhaul)。HST-SFN场景下一个典型的传输方案为将下行信号从一个BBU连接的所有的TRP同时发出，也就是说所有的TRP传输相同的码字、layer(层)、DMRS(Demodulation reference signals，解调参考信号)端口，多个TRP相当于组成了更多的径。当列车运行到相邻两个传输接收点TRP之间时，来自于两个 TRP的信号其中一个为负的多普勒频移，另一个为正的多普勒频移，这样会产生多普勒谱。由于列车移动速度很快，多普勒频移的变化范围有可能很大，从而导致终端不能很好地进行下行信号的解调。
为了解决终端接收到的来自不同的TRP存在相反的多普勒频移的问题，一种方法是在每个TRP分别进行多普勒频移的预补偿，以消除UE接收到的下行信号的多普勒扩展。但在现有技术中，UE检测SSB(Synchronization Signal block，同步信号块，有时也写作SS/PBCH block，Synchronization Signal/Physical Broadcast Channel Block，同步信号广播信道块)，根据检测到的SSB获得下行频点，并基于该下行频点获得上行频点，在所述上行频点上进行上行信号的传输。在UE处于移动状态时，UE获得的下行频点中包含了下行的多普勒频移，上行传输时又进一步叠加了上行的多普勒频移，因此，在单点传输时，上行信号在TRP接收时的频率相对于TRP侧的上行频点存在2倍的多普勒频率偏移。在多点传输时，各TRP的下行频点相同，但由于地理位置不同，在UE的多普勒频率偏移是不同的。但UE只确定出一个下行频点，并基于该下行频点进行上行信号的传输。由于各个TRP的地理位置和/或接收波束方向的不同，上行信号到达各个TRP经历的多普勒频移是不同的。由于TRP并不知道UE基于什么样的下行频点进行上行信号的传输，因此，TRP无法估计出下行或上行经历的多普勒频移，从而无法有效地进行多普勒频移的预补偿。
为了解决高铁SFN部署场景下从多个传输接收点同时发送数据时终端接收到的信号存在相反方向的多普勒而导致的解调性能不好的问题，本申请各实施例提供一种基于频率预补偿的多传输接收点的信号传输解决方案，即终端根据各个传输接收点TRP传输的下行信号分别确定出传输给各个传输接收点TRP的上行信号的传输频率(频点)，并使用所述传输频率分别进行各个上行信号的传输，以使得各个传输接收点可以分别获得终端相对于自己的多普勒频移，从而可以在各个传输接收点分别进行频率预补偿，消除终端侧的多普勒频移和多普勒扩展。本申请实施例提供的方法，可以适用的系统包括但不限于5G系统(例如NR(New Radio)系统)、LTE系统、6G系统、卫星系统、车联网系统，以及它们演进版本的系统等。
本申请各实施例中，网络设备可以为基站，基站可以包括多个传输接收 点TRP或TRP组。对于每个TRP，可以是该TRP发送第一下行信号，UE发送与之关联的上行信号，基站确定该TRP预补偿的频率。对于每个TRP组，可以是其中的一个TRP发送第一下行信号，UE发送与之关联的上行信号，基站确定TRP组里所有TRP预补偿的频率。其中，所述的TRP可以为RRH，TRP组可以RRH组。
本申请实施例提供的网络侧设备可以包含但不限于以下中的一种或多种：通常所用的基站、演进型基站(evolved node base station，eNB)、5G系统中的网络侧设备(例如下一代基站(next generation node base station，gNB)、发送和接收点(transmission and reception point，TRP))等设备。
本申请实施例提供的终端可以被称为用户设备UE等。终端可以包括但不限于手持设备、车载设备。例如，可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本或者个人数字助理(Personal Digital Assistant，PDA)等。
图1为本申请一实施例提供的信号的传输方法流程示意图，如图1所示，该方法的执行主体可以为终端(例如用户设备UE)，该方法至少包括如下步骤：
步骤100、接收多个第一下行信号；
HST-SFN场景下，UE接收多个传输接收点TRP分别下发的第一下行信号，即在例如HST-SFN场景下包括多个传输接收点TRP，每个TRP都会向进入到HST-SFN场景下的UE发送各自的第一下行信号。而且为了避免各TRP无法估计出下行或上行经历的多普勒频移，从而无法有效地进行多普勒频移的预补偿的现有技术问题，本申请实施例提供的方法中，每个TRP下发给UE的第一下行信号都与一上行信号具有关联关系，UE基于该关联关系发送上行信号。
步骤101、确定各所述第一下行信号对应的下行接收频率，并基于各第一下行信号对应的下行接收频率分别确定与各第一下行信号具有关联关系的各上行信号的传输频率；
UE接收多个第一下行信号后，可以首先确定各第一下行信号对应的下行接收频率。本申请实施例中所述的下行接收频率可以为所述第一下行信号到达UE的频率，或者为UE确定的该第一下行信号对应的下行频点。注意，由 于器件影响、信道估计不准、算法等因素，UE确定出的第一下行信号的下行接收频率有可能与下行信号到达UE的实际频率有偏差。一个频点是指一个参考频率，即可以用来确定下行射频信道和/或SSB和/或其他单元的频率位置的频率。例如，下行频点可以为用来确定下行信道(如PDSCH、PDCCH等)、SSB、下行参考信号(例如下行DMRS、CSI-RS、TRS)等一个或多个下行传输的频率的参考频率。例如，上行频点可以为用来确定上行信道(PUSCH、PUCCH、RACH等)、上行参考信号(例如SRS)等一个或多个上行传输的频率的参考频率。
可选地，UE根据其中的一个或多个第一下行信号确定出各第一下行信号对应的下行接收频率，所有各第一下行信号对应的下行接收频率相同。一个可能的方式是UE确定出一个下行频点，该频点作为UE确定的各第一下行信号对应的下行接收频率。
可选地，UE根据各个第一下行信号分别确定出各第一下行信号对应的下行接收频率，各第一下行信号对应的下行接收频率可以相同或不同。一种可能的方式为，UE针对每一个第一下行信号确定出一个下行频点，这些下行频点作为各第一下行信号对应的下行接收频率。
UE根据各第一下行信号对应的下行接收频率分别确定与各第一下行信号具有关联关系的各上行信号的传输频率的方式可以包括多种。
可选地，UE基于同一个下行接收频率确定各上行信号的传输频率。
可选地，UE确定一个下行频点，然后基于该下行频点结合上行和下行的频率偏差确定出上行频点。UE根据每个第一下行信号确定出该第一下行信号相对于下行频点的多普勒偏移，UE在确定一个上行信号的传输频率时使用该上行频点加上与根据该上行信号存在上述关联关系的第一下行信号的多普勒偏移确定该上行信号的实际频点，基于该实际频点确定上行信号的传输频率。
可选地，UE根据每个第一下行信号确定出该第一下行信号相对于下行频点的多普勒偏移，基于每个第一下行信号对应的多普勒偏移和所述下行频点确定出该第一下行信号的下行接收频率；然后基于该第一下行信号的下行接收频率结合上行和下行的频率偏差确定出每个上行信号的传输频率。
上述上行和下行的频率偏差可以是协议约定的，网络设备通过信令配置的，或者根据网络设备关于上行和/或下行的频率指示信息确定的。
可选地，UE根据每个第一下行信号分别确定一个下行接收频率，使用该下行接收频率确定该第一下行信号对应的上行信号的传输频率。
可选地，一个上行信号的传输频率为根据与它存在上述关联关系的第一下行信号的下行接收频率加上上行和下行的频率偏差后得到的频率确定的。步骤102、基于各上行信号的传输频率发送各所述上行信号。
UE确定出与每个第一下行信号具有关联关系的上行信号的传输频率后，便可以基于该传输频率分别向各TRP分别发送各自对应的上行信号，且使用不同的传输频率进行上行信号的发送。各TRP可以接收到UE发送的与其之前发送的第一下行信号具有关联关系的上行信号，并基于该上行信号确定出频率偏移进行频率预补偿，并给予预补偿后的传输频率向UE发送的后续的第二下行信号。
本申请实施例中，UE可以根据各个传输接收点传输的第一下行信号分别确定出传输给各个传输接收点的上行信号的传输频率(频点)，并使用所述传输频率分别进行各个上行信号的传输，以使得各个传输接收点可以分别获得终端相对于自己的多普勒频移，从而可以在各个传输接收点分别进行频率预补偿，消除终端侧的多普勒频移和多普勒扩展。
可以理解的是，本申请各实施例中所述的“第一下行信号”和“第二下行信号”是为了对同一个TRP先后两次向UE发送的下行信号进行区分，第一下行信号可以是首次发送给UE的下行信号，UE基于该第一下行信号不但可以确定与其关联的上行信号，还可以确定向TRP发送该上行信号所采用的传输频率。第二下行信号是TRP进行频率预补偿后发送的下行信号，这样可以降低信道估计的误差，提高下行传输的性能。注意第一下行信号和第二下行信号可以为不同的信号，也可以为同一信号的两次传输。例如，UE第一次传输一个TRS用于文中所述上行信号的传输时，这个TRS为第一下行信号；第二次再传输经过频率预补偿的该TRS时，这个TRS为第二下行信号。
本申请实施例提供的方法，终端为每个接收到的第一下行信号均确定出对应的下行接收频率，并基于该下行接收频率分别确定各上行信号的传输频率，各第一下行信号与各上行信号分别具有预设的关联关系，各个传输接收点可以独立地进行频偏估计和预补偿。由于每个传输接收点都进行了下行多普勒频偏的预补偿，因此降低了信道估计的误差，提高了下行传输的性能。
在上述实施例中，所述的关联关系包括以下一种或其组合：
所述上行信号的一个或多个信道特性和/或空间发送参数，可通过所述第一下行信号推导获得；
所述上行信号的接收端与所述第一下行信号的发送端为同一个网络设备，即上行信号的接收端与第一下行信号的发送端是准共址的(quasi co-located，QCL)。
基于上述的下行信号与上行信号的关联关系，可选地，目标信号所经历信道的某些特性是可以通过源信号来获得；或者，目标信号的空间发送参数可以通过源信号的空间接收参数来获得。

类型4(例如'QCL-TypeE'等):{Spatial parameter}或{空间相关信息SpatialRelationInofo}目标信号的空间发送参数可以通过源信号的空间接收参数来获得
类型5(例如'QCL-TypeF'等):{Doppler shift}
类型6：频率相关信息，目标信号的传输频率根据源信号确定；
类型7：一种包含Doppler shift的新的QCL类型。
一些可能的上行信号和下行信号的关联关系类型如下表1所示，关联关系中可能包含下表中的一种或多种，当包含多种时，可以为类型1/2/3/5/6+类型4的组合中的一种：

各所述上行信号被配置在不同的时间资源上，即各所述上行信号以时分复用的方式发送。具体地不同TRP对应的上行信号被配置在相同频域资源的不同的时间资源上，例如，不同的符号，不同的时隙，不同的RE等。这种方 式可以避免多个传输频点不一致的上行信号产生子载波间干扰，但会占用较多的时间资源。
可选地，各所述上行信号被配置不同的频域资源上，且相互间留有保护间隔，即各所述上行信号以频分复用，且在不同上行信号间留有保护间隔的方式发送。具体地，不同TRP对应的上行信号被配置在相同时间的不同的频域资源上，且相互间留有保护间隔，所述保护间隔可以是子载波级的、PRB级的等。这种方式可以节省时间资源，且可以避免多个传输频点不一致的上行信号产生子载波间干扰。
各所述上行信号不与其他用途的上行信号同时传输。
本申请实施例提供的方法，终端为每个接收到的第一下行信号均确定出对应的下行接收频率，并基于该下行接收频率分别确定各上行信号的传输频率，各第一下行信号与各上行信号分别具有预设的关联关系，各个传输接收点可以独立地进行频偏估计和预补偿。由于每个传输接收点都进行了下行多普勒频偏的预补偿，UE看到的来自于每一个传输接收点的信号都是补偿后的多普勒频偏。在没有误差的情况下，多普勒频偏被完全补偿掉了，则UE看到的来自于每个传输接收点的信号都没有多普勒频偏，降低了信道估计的误差，提高了下行传输的性能。
图2为本申请另一实施例提供的信号的传输方法流程示意图，如图2所示，该方法的执行主体可以是网络设备例如TRP或TRP组，以下以TRP为例进行介绍，该方法至少包括如下步骤：
步骤200、向终端发送第一下行信号，以供所述终端根据所述第一下行信号对应的下行接收频率确定与所述第一下行信号具有关联关系的上行信号的传输频率；
HST-SFN场景下，UE接收多个传输接收点TRP分别下发的第一下行信号，即在例如HST-SFN场景下包括多个传输接收点TRP，每个TRP都会向进入到HST-SFN场景下的UE发送各自的第一下行信号。而且为了避免各TRP无法估计出下行或上行经历的多普勒频移，从而无法有效地进行多普勒频移的预补偿的现有技术问题，本申请实施例提供的方法中，每个TRP下发给UE的第一下行信号都与一上行信号具有关联关系，UE基于该关联关系发送上行信号。
UE接收多个第一下行信号后，可以首先确定各第一下行信号对应的下行接收频率。本申请实施例中所述的下行接收频率是指UE接收到所述第一下行信号的接收频率。UE根据各第一下行信号对应的下行接收频率分别确定与各第一下行信号具有关联关系的各上行信号的传输频率的方式可以包括多种，具体方式与前述实施例相同，此处不再赘述。
步骤201、接收所述终端基于所述传输频率发送的、与所述第一下行信号具有所述关联关系的上行信号；
步骤202、基于所述上行信号确定频率偏移，确定第二下行信号的传输频率。
UE确定出与每个第一下行信号具有关联关系的上行信号的传输频率后，便可以基于该传输频率分别向各TRP分别发送各自对应的上行信号，且使用不同的传输频率进行上行信号的发送。
各TRP可以接收到UE发送来的与其之前发送的第一下行信号具有关联关系的上行信号，并基于该上行信号确定出频率偏移进行频率预补偿，并给予预补偿后的传输频率向UE发送的后续的第二下行信号。
可选地，网络中包含多个TRP，各TRP分别发送不同的第一下行信号。每个TRP基于与自己发送的第一下行信号具有所述关联关系的上行信号确定频率偏移，并利用所述频率偏移确定自己发送的第二下行信号的传输频率。
可选地，网络中包含多个TRP，多个TRP被进行了分组。每个TRP包括一个或多个TRP。各TRP组分别发送不同的第一下行信号(每个TRP组中可以有一个或多个TRP发送第一下行信号)。每个TRP组基于与自己发送的第一下行信号具有所述关联关系的上行信号确定自己对应的频率偏移，并利用所述频率偏移确定自己包含的TRP发送的第二下行信号的传输频率。
本申请实施例中，UE可以根据各个传输接收点传输的第一下行信号分别确定出传输给各个传输接收点的上行信号的传输频率(和/或频点)，并使用所述传输频率分别进行各个上行信号的传输，以使得各个传输接收点可以分别获得终端相对于自己的多普勒频移，从而可以在各个传输接收点分别进行频率预补偿，消除终端侧的多普勒频移和多普勒扩展。
可以理解的是，本申请各实施例中所述的“第一下行信号”和“第二下行信号”是为了对同一个TRP先后两次向UE发送的下行信号进行区分，第一 下行信号可以是首次发送给UE的下行信号，UE基于该第一下行信号不但可以确定与其关联的上行信号，还可以确定向TRP发送该上行信号所采用的传输频率。第二下行信号是TRP进行频率预补偿后发送的下行信号，这样可以降低信道估计的误差，提高下行传输的性能。注意第一下行信号和第二下行信号可以为不同的信号，也可以为同一信号的两次传输。例如，UE第一次传输一个TRS用于文中所述上行信号的传输时，这个TRS为第一下行信号；第二次再传输经过频率预补偿的该TRS时，这个TRS为第二下行信号。
本申请实施例提供的方法，终端为每个接收到的第一下行信号均确定出对应的下行接收频率，并基于该下行接收频率分别确定各上行信号的传输频率，各第一下行信号与各上行信号分别具有预设的关联关系，各个传输接收点可以独立地进行频偏估计和预补偿。由于每个传输接收点都进行了下行多普勒频偏的预补偿，因此降低了信道估计的误差，提高了下行传输的性能。
在上述实施例的基础上，网络设备配置或指示上行信号与下行信号的关联关系，以使得终端可以根据下行信号确定上行信号的传输频率(和/或频点)。一种终端根据下行信号确定上行信号的传输频率的方式为：终端根据一个下行信号确定它对应的下行频率(和/或频点)，然后基于这个下行频率和上下行频率差就可以确定出上行信号的频率(和/或频点)。例如，终端确定的下行频点为f DL，上下行频率差为上行频点比下行频点大f d，则可以确定出上行频率为f DL+f d。
本实施例中TRP配置关联关系和向UE下发第一下行信号的步骤可以不分先后。UE根据配置或指示的所述关联关系，利用检测到的第一下行信号确定与之具有上述关联关系的上行信号的传输频率(例如，频点)，并根据关于所述上行信号的配置或指示在该传输频率上传输所述上行信号。各TRP分别接收对应自己的上行信号，TRP使用对应于自己的上行信号确定频率偏移，利用所述频率偏移确定后续的下行传输的传输频率(对下行信号的传输进行频率预补偿)。所述对应于TRP的上行信号是指与该TRP发送的下行信号具有上述关联关系的上行信号。
在上述实施例中，所述的步骤202可以包括：
步骤2021、基于所述频率偏移，确定后续的下行信号的频率调整值；
步骤2022、使用所述频率调整值，确定后续的下行信号(第二下行信号) 的传输频率。
其中，TRP根据对应自己的上行信号确定频率偏移的一种方式为：TRP接收对应于自己的上行信号，进行频偏估计，利用频偏估计获得用于预补偿的频率偏移值。
可选地，一个TRP发送的后续的下行信号的所述预补偿的频率偏移值等于该TRP利用与自己发送的第一下行信号具有关联关系的上行信号得到的频偏估计值的函数。例如，一个TRP发送的后续的下行信号的所述预补偿的频率偏移值等于该TRP利用与自己发送的第一下行信号具有关联关系的上行信号得到的频偏估计值。例如，一个TRP发送的后续的下行信号的所述预补偿的频率偏移值等于该TRP利用与自己发送的第一下行信号具有关联关系的上行信号得到的频偏估计值的负值。例如，一个TRP发送的后续的下行信号的所述预补偿的频率偏移值等于该TRP利用与自己发送的第一下行信号具有关联关系的上行信号得到的频偏估计值的一半。例如，一个TRP发送的后续的下行信号的所述预补偿的频率偏移值等于该TRP利用与自己发送的第一下行信号具有关联关系的上行信号得到的频偏估计值的一半的负值。
可选地，网络中存在多个TRP，这些TRP被进行了分组，一个TRP组内所有TRP一个TRP发送的后续的下行信号的所述预补偿的频率偏移值等于该TRP组利用与自己发送的第一下行信号具有关联关系的上行信号得到的频偏估计值的函数。例如，一个TRP组内所有TRP发送的后续的下行信号的所述预补偿的频率偏移值等于该TRP组利用与自己发送的第一下行信号具有关联关系的上行信号得到的频偏估计值。例如，一个TRP组内所有TRP发送的后续的下行信号的所述预补偿的频率偏移值等于该TRP组利用与自己发送的第一下行信号具有关联关系的上行信号得到的频偏估计值的负值。例如，一个TRP组内所有TRP发送的后续的下行信号的所述预补偿的频率偏移值等于该TRP组利用与自己发送的第一下行信号具有关联关系的上行信号得到的频偏估计值的一半。例如，一个TRP组内所有TRP发送的后续的下行信号的所述预补偿的频率偏移值等于该TRP组利用与自己发送的第一下行信号具有关联关系的上行信号得到的频偏估计值的负值。
可选地，使用所述频率调整值，确定后续的下行信号的传输频率的方式为：确定后续的下行信号(第二下行信号)的频点为原频点增加所述频率调 整值，基于该频点确定所述后续的下行信号的发送频率。
可选地，使用所述频率调整值，确定后续的下行信号的传输频率的方式为：确定后续的下行信号(第二下行信号)的频点为原频点减去所述频率调整值，基于该频点确定所述后续的下行信号的发送频率。
可选地，使用所述频率调整值，确定后续的下行信号的传输频率的方式为：确定后续的下行信号的传输频率为频率预补偿前的频率加上所述频率调整值。
可选地，使用所述频率调整值，确定后续的下行信号的传输频率的方式为：确定后续的下行信号的传输频率为频率预补偿前的频率减去所述频率调整值。
可选地，使用所述频率调整值，确定后续的下行信号的传输频率包括：确定各TRP对应的下行频点为原频点增加各TRP分别对应的所述频率调整值。
可选地，使用所述频率调整值，确定后续的下行信号的传输频率包括：确定各TRP对应的下行频点为各TRP的原频点减去各TRP分别对应的所述频率调整值。
可选地，使用所述频率调整值，确定后续的下行信号的传输频率包括：确定一个TRP组内的TRP对应的下行频点为该TRP组的原频点增加该TRP组对应的所述频率调整值。
可选地，使用所述频率调整值，确定后续的下行信号的传输频率包括：确定一个TRP组内的TRP下行频点为各TRP的原频点减去各TRP分别对应的所述频率调整值。
可选地，使用所述频率调整值，确定后续的下行信号的传输频率的方式为各个TRP分别使用所述频率调整值，确定后续的下行信号的传输频率。
例如，频偏估计的结果为f d,预补偿的频率偏移值为-f d/2，频偏估计的算法可以使用现有技术中的一些频偏估计算法。TRP使用-f d/2对第二下行信号的发送频率进行预补偿，则UE接收下行信号时只剩下了很小的频率偏移。上述频率偏移值估计为对上行信号的接收频率与上行实际频点的差值的估计。
可选地，对于用于确定预补偿频率偏移的第一下行信号，UE不进行频率预补偿。这样TRP可以一直使用相同的频偏预补偿确定方法。
可选地，TRP在UE第一次接入本TRP时使用一种预补偿频率确定方法，在后续过程中使用另外一种预补偿频率确定方法。例如，在UE第一次接入时，若TRP估计出的频率偏移值为f d，TRP可以使用-f d/2对下行信号的发送频率进行预补偿；在后续使用上行信号进行预补偿频率估计时，若TRP估计出的频率偏移值为f d’，TRP可以使用-f d’对下行信号的发送频率进行预补偿。

可选地，所述第一下行信号的配置信息或触发信息中还包含标识信息，所述标识信息用于指示与所述第一下行信号存在所述关联关系的所述上行信号在所述上行信号所在资源集合的位置。

在上述各实施例的基础上，各所述上行信号的发送方式，包括以下任一种或其组合：
各所述上行信号被配置在不同的时间资源上，具体地不同TRP对应的上行信号被配置在相同频域资源的不同的时间资源上，例如，不同的符号，不同的时隙，不同的RE等。这种方式可以避免多个传输频点不一致的上行信号产生子载波间干扰，但会占用较多的时间资源。
可选地，各所述上行信号被配置不同的频域资源上，且相互间留有保护间隔，具体地，不同TRP对应的上行信号被配置在相同时间的不同的频域资源上，且相互间留有保护间隔，所述保护间隔可以是子载波级的、PRB级的等。这种方式可以节省时间资源，且可以避免多个传输频点不一致的上行信号产生子载波间干扰。
各所述上行信号不与其他用途的上行信号同时传输。
本申请实施例提供的方法，终端为每个接收到的第一下行信号均确定出对应的下行接收频率，并基于该下行接收频率分别确定各上行信号的传输频率，各第一下行信号与各上行信号分别具有预设的关联关系，各个传输接收点可以独立地进行频偏估计和预补偿。由于每个传输接收点都进行了下行多普勒频偏的预补偿，UE看到的来自于每一个传输接收点的信号都是补偿后的多普勒频偏。在没有误差的情况下，多普勒频偏被完全补偿掉了，则UE看到的来自于每个传输接收点的信号都没有多普勒频偏，降低了信道估计的误差，提高了下行传输的性能。
以下本申请实施例提出的基站频率预补偿方案的一个示例，例如：
一个BBU连接了4个TRP，具体为4个RRH，按照列车的运行方向，列车经过这些RRH的顺序将是RRH1、RRH2、RRH3和RRH4。表3给出了频率预补偿前后来自于各RRH的下行信号到达UE时的频率比较表格。其中，假设RRH和终端的多普勒频偏估计为理想估计，RRH1、RRH2、RRH3和RRH4单向的多普勒频移分别为f 1、f 2、f 3和f 4，频率预补偿值为RRH根据接收到的上行信号确定的多普勒频偏的二分之一。由此可见，在本申请实施例中，UE接收到的来自于各个RRH的下行信号的多普勒频移可以被消除，从而使得UE可以获得更好的下行接收性能。
