背景技术
在多发送接收点(Transmission Reception Point,TRP)的场景中，尤其是单频网络(Single Frequency Network，SFN)传输场景，网络中存在多个TRP向用户设备(User Equipment，UE，也称终端)传输数据，但是由于UE与多个TRP的距离不同，来自各TRP的传输信号到达UE的时延、相位和多普勒频偏存在不同。尤其是来自各TRP对应的多普勒频偏差异较大，这会严重影响UE的接收性能。

如图2所示，本申请实施例提供一种多普勒频偏上报方法，包括：
步骤201，终端进行至少一个发送接收点TRP对应的多普勒频偏测量；
步骤202，终端根据所述测量结果，向网络侧设备发送多普勒频偏上报信息；
需要说明的是，所述多普勒频偏上报信息用于指示终端测量得到的至少一个TRP对应的多普勒频偏信息。
可选地，该多普勒频偏信息可以为多普勒频偏值，可以为多普勒频偏值的差值，还可以为多普勒频偏值的差值的绝对值。
需要说明的是，该多普勒频偏上报信息用于辅助网络侧设备进行发射信号频率的预处理；网络侧设备在接收到多普勒频偏上报信息后，可以依据该多普勒频偏上报信息进行发射信号频率的预处理，以此提升终端的接收性能。
可选地，本申请的步骤201的一种可选地实现方式为：
步骤2011，终端接收网络侧设备发送的第一配置信息；
其中，所述第一配置信息用于指示多普勒频偏上报所关联的目标测量资源，所述目标测量资源用于多普勒频偏测量，所述目标测量资源包括至少一个目标资源集。
步骤2012，根据所述第一配置信息进行至少一个TRP对应的多普勒频偏测量；
也就是说，此种情况下，终端是依据网络侧设备配置的多普勒频偏上报所关联的目标测量资源进行多普勒频偏测量，在进行多普勒频偏测量之后，终端能够得到每一个TRP所对应的多普勒频偏值。
可选地，该目标资源集包括以下至少一项：

B11、信道状态信息(Channel State Information，CSI)资源配置中的目标测量资源；
也就是说，此种情况下，该目标测量资源为CSI资源配置(CSI resource setting)中配置的测量资源，例如，目标测量资源为CSI资源配置中的至少一个TRS资源集。
B12、第一参数，所述第一参数用于指示CSI资源配置中的第一测量资源集与目标测量资源的绑定关系；
需要说明的是，该第一测量资源集能够划分为多个测量资源子集，每个测量资源子集中的每个资源均关联一个目标资源集。
这里需要说明的是，该第一参数用于显示指示CSI资源配置中的第一测量资源集与目标测量资源的绑定关系，例如，第一参数用于显示指示CSI资源配置中的第一测量资源集与TRS资源集的绑定关系。
应用情况一、显式配置多普勒频偏信息上报所关联的TRS资源集：
假设在一个CSI资源配置中配置了一个非零功率信道状态信息参考信号(Non-Zero Power Channel State Information Reference Signal，NZP-CSI-RS) 资源集，且所述CSI资源配置关联一个CSI上报配置(CSI report setting)。所述NZP-CSI-RS资源集中的NZP-CSI-RS资源分为两个子集，假设，子集1中包含的NZP-CSI-RS资源为NZP-CSI-RS1、NZP-CSI-RS2；子集2中包含的NZP-CSI-RS资源为NZP-CSI-RS3、NZP-CSI-RS4。网络侧设备通过显式的无线资源控制(Radio Resource Control，RRC)参数来指示NZP-CSI-RS1、NZP-CSI-RS2、NZP-CSI-RS3、NZP-CSI-RS4关联的TRS资源集分别为TRS1、TRS2、TRS3、TRS4，以用于多普勒频偏信息的测量和上报。在这种情况下，TRS资源不是作为CSI资源配置中的测量资源进行直接配置，而是通过与CSI资源配置中配置的NZP-CSI-RS资源集之间的关联关系进行间接配置，以到达多普勒频偏信息测量和上报的效果。
终端接收到网络侧设备的配置信息后，子集1中的NZP-CSI-RS资源通过TRP1进行传输，终端基于子集1中的NZP-CSI-RS资源测量TRP1相关的CSI信息，包括预编码矩阵指示(Precoding Matrix indicator，PMI)/秩指示(Rank Indicator，RI)/信道质量指示(Channel Quality Indicator，CQI)等信息，且与之绑定的TRS1、TRS2也通过TRP1进行传输，终端基于TRS1、TRS2测量TRP1的多普勒频偏值等信息；而子集2中的NZP-CSI-RS资源通过TRP2进行传输，终端基于子集2中的NZP-CSI-RS资源测量TRP2相关的CSI信息，包括PMI/RI/CQI等信息，且与之绑定的TRS3、TRS4也通过TRP2进行传输，终端基于TRS3、TRS4测量TRP2的多普勒频偏值等信息。
B13、CSI资源配置中的第二测量资源集对应的准共址(Quasi Co-location,QCL)参考源；
需要说明的是，所述第二测量资源集能够划分为多个测量资源子集，每个测量资源子集中的每个资源均关联一个目标资源集作为QCL参考源。
应用情况二、隐式配置多普勒频偏信息上报所关联的TRS资源集：
假设在一个CSI资源配置中配置了一个NZP-CSI-RS资源集，且关联一个CSI上报配置。所述NZP-CSI-RS资源集中的NZP-CSI-RS资源分为两个子集；假设子集1中包含的NZP-CSI-RS资源为NZP-CSI-RS1、NZP-CSI-RS2；子集2中包含的NZP-CSI-RS资源为NZP-CSI-RS3、NZP-CSI-RS4。网络侧配置NZP-CSI-RS1、NZP-CSI-RS2、NZP-CSI-RS3、NZP-CSI-RS4的QCL参 考源为TRS资源集TRS1、TRS2、TRS3、TRS4。在这种情况下，终端基于所述NZP-CSI-RS资源QCL参考源的TRS资源集，进行多普勒频偏的测量和上报。在这种情况下，TRS资源不是作为CSI资源配置中的测量资源进行直接配置，而是通过与CSI资源配置中配置的NZP-CSI-RS资源集之间的QCL参考关系进行间接配置，以到达多普勒频偏信息测量和上报的效果。
终端接收到网络侧设备的配置信息后，子集1中的NZP-CSI-RS资源通过TRP1进行传输，终端基于子集1中的NZP-CSI-RS资源测量TRP1相关的CSI信息，包括PMI/RI/CQI等信息，且与之绑定的TRS1、TRS2也通过TRP1进行传输，终端基于TRS1、TRS2测量TRP1的多普勒频偏值等信息；而子集2中的NZP-CSI-RS资源通过TRP2进行传输，终端基于子集2中的NZP-CSI-RS资源测量TRP2相关的CSI信息，包括PMI/RI/CQI等信息，且与之绑定的TRS3、TRS4也通过TRP2进行传输，终端基于TRS3、TRS4测量TRP2的多普勒频偏值等信息。
可选地，本申请实施例的步骤202的一种可以采用的实现方式为：
步骤2021，终端接收网络侧设备发送的第二配置信息；
步骤2022，根据所述第二配置信息，向网络侧设备发送多普勒频偏上报信息。
可选地，该第二配置信息用于指示以下至少一项：
C11、普勒频偏信息上报所关联的CSI上报的上报量配置；
需要说明的是，该多普勒频偏信息上报所关联的CSI上报的上报量配置用于指示包括以下至少一项：
C111、终端上报独立的多普勒频偏信息；
C112、终端上报多普勒频偏信息和第一CSI上报信息；
需要说明的是，所述第一CSI信息包括以下至少一项：CSI-RS资源指示(CSI-RS Resource Indicator，CRI)、预编码矩阵指示(PMI)、秩指示(RI)、信道质量指示(CQI)、层指示(Layer Indicator，LI)、参考信号测量功率(Reference Signal Received Power，RSRP)和信干噪比(Signal-to-Noise and Interference Ratio，SINR)。
可选地，在C112的情况下，在步骤202之前，所述方法还包括：
接收网络侧设备发送的多普勒频偏上报信息的第一上报周期；
其中，所述第一上报周期包括以下至少一项：
D11、周期取值；
也就是说，该第一上报周期中包含的是具体的周期取值。
D12、多普勒频偏上报信息的上报周期与所述第一CSI上报信息的上报周期的倍数关系。
这里需要说明的是，多普勒频偏信息的上报周期可与第一CSI上报信息的上报周期相同，也可以不同。还需要说明的是，当终端未接收到网络侧设备发送的第一上报周期的情况下，终端默认多普勒频偏上报信息的上报周期与第一CSI上报信息的上报周期相同。
应用情况三、CSI上报与多普勒频偏信息上报的周期不同
假设网络侧设备在CSI上报配置中配置CSI上报的周期为A。
1)若不额外配置第一上报周期，则默认TRS资源集测量的多普勒频偏信息的上报周期也为A。此时，多普勒频偏上报信息与CSI上报配置中配置的其他CSI上报信息可在同一物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)资源中进行复用和上报，或分别在不同的上报资源中独立上报。
2)若额外配置了第一上报周期，则TRS资源集测量的多普勒频偏信息的上报周期为第一上报周期所对应的上报周期B。此时，当多普勒频偏信息的上报时间与CSI上报配置中配置的其他CSI上报信息的上报时间重合，两者可在同一PUCCH或PUSCH资源中进行复用和上报，或者分别在不同的上报资源中独立上报；而当CSI上报配置中配置的其他CSI上报信息的上报时间到来，但多普勒频偏信息的上报时间未到达时，则终端只上报其他CSI上报信息，不上报多普勒频偏信息。
进一步需要说明的是，上述提到的多普勒频偏信息包括以下至少一种形式：
C21、多普勒频偏值；
需要说明的是，当终端对几个TRP进行测量，则此种情况下，多普勒频偏信息中便包括几个多普勒频偏值，也就是说，TRP与多普勒频偏值是一一 对应的，即多普勒频偏信息中包括至少一个多普勒频偏值，可以理解，此处以及后续提到的多普勒频偏值指的是至少一个多普勒频偏值。
可选地，在此种情况下，所述终端上报以下至少一项：
C211、上报多普勒频偏值的差分量化结果；
需要说明的是，此种情况下，可以理解为选择至少一个多普勒频偏值中的一个(可以为取值最大的一个、最小的一个或任一个)或者利用至少一个多普勒频偏值中确定的一个值作为基准进行量化，其他的多普勒频偏值取与基准的差值进行量化。
应用情况三、当终端上报多个多普勒频偏值时，进行差分量化
假设用于多普勒频偏信息测量和上报的TRS资源集分别为TRS1和TRS2，且分别通过TRP1和TRP2进行传输，终端基于TRS1测量来自TRP1的信号的多普勒频偏，基于TRS2测量来自TRP2的信号的多普勒频偏。终端测量两个TRP对应的多普勒频偏分别得到多普勒频偏值1和多普勒频偏值2，并进行上报。为了节省上报的比特开销，对需要上报的多普勒频偏值1和多普勒频偏值2进行差分量化。量化方法包括如下至少一种：
1)以多普勒频偏值1和多普勒频偏值2中绝对值最大者为量化基准，采用M比特对其进行量化。而绝对值较小者只上报其与最大者的绝对值差值，并采用N比特对其进行量化，其中N<M；
2)以多普勒频偏值1和多普勒频偏值2中数值最大者为量化基准，采用M比特对其进行量化，而数值较小者只上报其与最大者的差值，并采用L比特对其进行量化。
C212、上报多普勒频偏值的正负性以及多普勒频偏值的绝对值的量化结果；
需要说明的是，此种情况下是上报每个多普勒频偏值的正负性，通常用1比特进行指示正负性，然后对每个多普勒频偏值的绝对值进行量化，量化方式可以为差分量化、均匀量化、非均匀量化等，因此针对每个多普勒频偏值均包括两部分比特，即正负性指示比特部分以及量化比特部分，两部分组合成比特序列后进行上报。
应用情况四、当终端上报多普勒频偏值时，上报多普勒频偏值的正负性
假设用于多普勒频偏信息测量和上报的TRS资源集分别为TRS1和TRS2，且分别通过TRP1和TRP2进行传输，终端基于TRS1测量来自TRP1的信号的多普勒频偏，基于TRS2测量来自TRP2的信号的多普勒频偏。
终端测量两个TRP对应的多普勒频偏分别为多普勒频偏值1和多普勒频偏值2。其中，多普勒频偏值1为一正值，多普勒频偏值2为一负值。采用比特‘0’指示正符号，比特‘1’指示负符号，其中，比特‘0’和‘1’的含义可以互换。并采用额外X个比特对多普勒频偏值1、多普勒频偏值2的绝对值进行量化，所述绝对值的量化方法包括差分量化、均匀量化、非均匀量化。量化后，终端上报的多普勒频偏值1和多普勒频偏值2的1比特符号指示和X比特多普勒频偏值的绝对值的量化比特。
C213、上报多普勒频偏值中的第一目标多普勒频偏值的正负性以及多普勒频偏值的差分量化结果，所述第一目标多普勒频偏值为所述差分量化的差分计算基准。
所述差分计算基准包括以下一项：
C31、所述多普勒频偏值中的绝对值最大者；
C32、所述多普勒频偏值中的绝对值最小者；
C33、所述多普勒频偏值的平均值。
C22、多普勒频偏值与基准值的至少一个差值；
需要说明的是，该基准值为多普勒频偏值中的一者，在进行差值的确定时，先进行基准值的确定，该基准值用于作为被减数或减数；也就是说，若存在X个多普勒频偏值，则最后会确定得到X-1个差值。
应用情况五、当终端上报一个多普勒频偏信息的差值时：
假设用于多普勒频偏信息测量和上报的TRS资源集分别为TRS1和TRS2，且分别通过TRP1和TRP2进行传输，终端基于TRS1测量来自TRP1的信号的多普勒频偏，基于TRS2测量来自TRP2的信号的多普勒频偏。终端测量两个TRP对应的多普勒频偏分别得到多普勒频偏值1和多普勒频偏值2。
网络侧设备通过下行控制信息(Downlink Control Information，DCI)/媒体接入控制层(Medium Access Control，MAC)控制单元(Control Element，CE)中的两个传输配置指示(Transmission Configuration Index，TCI)状态 (states)向终端指示物理下行共享信道(Physical Downlink Shared Channel，PDSCH)或者物理下行控制信道(Physical Downlink Control Channel，PDCCH)的下行解调参考信号(Downlink Modulation Reference Signal，DMRS)的QCL参考为TRS1和TRS2。假设TRS1为PDSCH或者PDCCH的DMRS提供频偏参考。那么在这种情况下，网络侧设备和终端侧多普勒频偏的差值计算以TRS1的测量结果对应的多普勒频偏值1为计算基准，即差值＝多普勒频偏值1-多普勒频偏值2，或者，差值＝多普勒频偏值2-多普勒频偏值1。
C23、多普勒频偏值与基准值的至少一个差值的绝对值；
可选地，在此种情况下，终端还需要上报多普勒频偏值与基准值的差值的正负性。
需要说明的是，该基准值为多普勒频偏值中的一者，在进行差值的确定时，先进行基准值的确定，该基准值用于作为被减数或减数；也就是说，若存在X个多普勒频偏值，则最后会确定得到X-1个差值的绝对值，X≥2，因通过绝对值并不知道两个多普勒频偏值的大小，所以在此种情况下，终端还需要上报至少一个多普勒频偏值与基准值的差值的正负性，也就是说，针对每一个差值，终端均包括两部分比特，即正负性指示比特以及绝对值指示比特。
应用情况六、当终端上报一个多普勒频偏差值的绝对值时：
假设用于多普勒频偏信息测量和上报的TRS资源集分别为TRS1和TRS2，且分别通过TRP1和TRP2进行传输，终端基于TRS1测量来自TRP1的信号的多普勒频偏，基于TRS2测量来自TRP2的信号的多普勒频偏。终端测量两个TRP对应的多普勒频偏分别得到多普勒频偏值1和多普勒频偏值2。
终端计算多普勒频偏值1和多普勒频偏值1的差值的绝对值，即差值的绝对值＝|多普勒频偏值1-多普勒频偏值2|。若所述差值绝对值为一正值，则采用比特‘0’表示；若所述差值绝对值为一负值，则采用比特‘1’表示。其中，比特‘0’和‘1’的含义可以互换。另外，采用额外Y个比特对所述差值的绝对值进行量化，具体地，该量化方式可以为差分量化、均匀量化、非均匀量化等。
这里需要说明的是，上述C22和C23中的基准值为网络侧设备指示的传 输配置指示(TCI)状态中提供频偏QCL参考的目标资源集所测量得到的多普勒频偏值。
或者，所述基准值对应的第一基准信息由网络侧设备通过RRC信令配置给终端，该第一基准信息用于确定所述基准值，例如，该第一基准信息为测量信号/配置等信息，该测量信号/配置等信息与特定的基准值对应，则通过第一基准信息便可以确定基准值。
或者，所述多普勒频偏上报信息中包括第一标识信息，所述第一标识信息用于指示获取多普勒频偏差值的基准值对应的第二基准信息，该第二基准信息用于确定所述基准值，该第二基准信息为测量信号/配置等信息，该测量信号/配置等信息与特定的基准值对应，则通过第二基准信息便可以确定基准值。
需要说明的是，当协议约定或高层配置终端可以采用C21-C23中的至少两种方式进行多普勒频偏信息上报，则在进行具体的上报时，网络侧设备可以灵活配置终端在不同时刻使用哪种方式进行上报，可选地，所述方法，还包括：
终端接收网络侧设备发送的第一上报指示信息，所述第一上报指示信息用于指示进行所述多普勒频偏信息上报的切换。
例如，若协议约定或高层配置终端可以采用两种方式进行多普勒频偏信息上报，则终端每接收一次第一上报指示信息，则更改一次上报方式；若协议约定或高层配置终端可以采用三种方式进行多普勒频偏信息上报，则该第一上报信息中通常需要包括终端切换后的上报方式，终端接收到该第一上报指示信息后，将上报方式切换为第一上报指示信息中所指示的上报方式。
例如，协议约定终端可以采用C21和C22的方式进行多普勒频偏信息上报，当在时刻1网络侧设备配置终端使用C21的上报方式，而在时刻2网络侧设备想要改变终端的上报方式，则网络侧设备需要向终端发送第一上报指示信息，终端接收到该第一上报指示信息后便知道网络侧设备进行上报方式的切换，则在下次上报时采用C22的上报方式进行多普勒频偏信息上报。
C12、多普勒频偏信息上报所关联的CSI上报的上报时机配置；
可选地，所述上报时机配置包括以下至少一项：
周期性上报；
半持续上报；
非周期上报。
也就是说在此种情况下，终端在多普勒频偏信息上报所对应的上报时机向网络侧设备发送多普勒频偏上报信息。
可选的，还需要说明的是，终端还可以依据网络侧设备发送的指示信息，确定是否需要进行多普勒频偏上报信息的发送，可选地，本申请实施例的方法还包括：
接收网络侧设备通过无线资源控制(RRC)信令发送的第一指示信息，所述第一指示信息用于指示是否进行多普勒频偏信息上报。
进一步地，当终端在接收到该第一指示信息后，若所述第一指示信息指示需要进行多普勒频偏信息上报，则终端在多普勒频偏信息上报所对应的上报时机向网络侧设备发送多普勒频偏上报信息。
也就是说，此种情况下，终端并不是主动进行多普勒频偏上报信息的上报，只有在网络侧设备指示需要获取多普勒频偏上报信息时，终端才发送多普勒频偏上报信息给网络侧设备，以此可以降低多普勒频偏上报信息的发送频率，降低信令开销。而当网络侧设备不支持接收终端上报多普勒频偏信息的情况下，网络侧设备也可向终端指示第一指示信息。
可选地，还需要说明的是，网络侧设备可以依据终端的能力确定是否需要进行多普勒频偏信息上报，本申请实施例的方法还包括：
向网络侧设备发送终端能力信息，该终端能力信息用于指示终端是否支持多普勒频偏信息的上报。
当网络侧设备接收到该终端能力信息后，在所述终端能力信息指示终端支持多普勒频偏信息的上报，网络侧设备可以发送第一指示信息给终端，以使得终端在进行多普勒频偏测量之后，进行多普勒频偏信息的上报；或者当网络侧设备接收到该终端能力信息后，在所述终端能力信息指示终端支持多普勒频偏信息的上报，发送第一配置信息用于指示终端进行多普勒频偏测量，终端在进行多普勒频偏测量之后，在多普勒频偏信息上报所对应的上报时机向网络侧设备发送多普勒频偏上报信息；上述的方式能够避免网络侧设备发 送无效配置信息情况的出现，以此保证通信的有效性。
应用情况八、当终端接收PDSCH数据时：
1)以MAC CE中的某一个TCI码点(codepoint)中的第一个TCI state作为调节下行载频的基准，所述MAC CE用于激活PDSCH关联的TCI state，所述TCI state为PDSCH的DMRS提供包括频偏的QCL参考。
2)以PDCCH DMRS关联的TCI state作为调节下行载频的基准。
