下面将对本申请中的相关术语或背景进行介绍；
一、信道状态信息的获取
由信息论可知，准确的信道状态信息(Channel State Information，CSI) 对信道容量的至关重要。尤其是对于多天线系统来讲，发送端可以根据CSI优化信号的发送，使其更加匹配信道的状态。如：信道质量指示(Channel Quality Indicator，CQI)可以用来选择合适的调制编码方案(Modulation and Coding Scheme，MCS)实现链路自适应；预编码矩阵指示(Precoding Matrix Indicator，PMI)可以用来实现特征波束成形(beamforming)从而最大化接收信号的强度，或者用来抑制干扰(如小区间干扰、多用户之间干扰等)。因此，自从多天线技术(Multi-Input Multi-Output，MIMO)被提出以来，CSI获取一直都是研究热点。
通常，CSI获取主要分为两种方式：一种是显式反馈，如CQI、PMI的反馈等；另一种是隐式反馈，如利用信道互易性等。对于大规模天线阵列系统(massive MIMO)，由于天线数目较大，显式反馈的资源开销较大，所以基于信道互易性的隐式反馈备受青睐。
利用信道互易性获取CSI的典型情况是终端向网络发送探测参考信号(Sounding Reference Signal，SRS)，然后网络根据SRS做信道估计，从而获得上行信道的信息。然后，根据信道互易性，网络将所述上行信道的信息转化为下行信道的信息并据此确定下行数据传输的预编码矩阵。
其中，信道互易性存在于时分双工(Time Division Duplex，TDD)系统中。例如，在角度域，下行信道的离开角(Angle of Departure，AoD)等于上行信道的到达角(Angle of Arrival，AoA)；在时延域，上下行信道具有相同的信道冲激响应(Channel Impulse Response，CIR)。
然而，在实际测量中发现，在频分双工(Frequency Division Duplex，FDD)系统中，上下行信道也存在一定程度的互易性：在角度域，下行信道的AoD等于上行信道的AoA；在时延域，上下行信道具有相同的功率时延谱(Power Delay Profile，PDP)，也即上下行信道具有相同的多径时延和多径功率。但是，各个径的相位不同。为了区别于TDD系统中的完全信道互易性(full reciprocity)，FDD系统中的这种一定程度的互易性被称为部分信道互易性(partial reciprocity)。
二、信道互易性
在部分互易性系统中，网络基于终端发送的SRS进行信道估计可以得到 上行信道的冲激响应。从而，获取多径信道各个径的时延以及幅度。为了获取各个径的相位，通常有以下两种方式。
方式1：网络直接指示终端各个径的时延。对于终端而言，基于信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)进行信道估计从而获得下行信道的冲激响应，然后根据网络配置的各个径的时延通过IDFT变换，获得各个径相位，并将其上报给网络。
方式2：网络将多条径映射到多个CSI-RS端口上。其中，对每个CSI-RS端口进行频率选择性预编码(Frequency Selective Precoding)，频率选择性预编码有两种基本的实现方法，一种是小时延循环延时分集(Small Delay Cyclic Delay Diversity，SD-CDD)，且频率选择性预编码对应的时延为与其对应的径的时延。终端侧进行简单操作(如相加)后获得与该CSI-RS端口对应的径的冲激响应分量(一个复数)，并将该冲激响应分量(包括相位和幅度)或者其相位上报给网络。假设一个CSI-RS符号(一个正交相移键控(Quadrature Phase Shift Keying，QPSK)符号)可以表示为x k，k为其对应的子载波映射位置，那么对其进行频率选择性预编码之后的符号可以表示为
Figure PCTCN2021123821-appb-000001
其中，

为虚数单位；N为正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号对应的快速傅里叶变换(Fast Fourier Transform，FFT)点数；τ为该频率选择性预编码对应的时延。
另一种是基站根据空频二维奇异值分解(Singular value decomposition，SVD)获得联合的预编码，将若干个空频基向量映射到若干个端口上，和第一种方法的区别在于基站对预编码的处理上，在终端侧，都是进行简单操作(如相加)后获得与该CSI-RS端口对应的径的冲激响应分量(一个复数)，并将该冲激响应分量(包括相位和幅度)或者其相位上报给网络。
目前，在上下行信道仅有部分互易性的情况下，网络侧在为下行传输进行预编码设计时，绝大多数方案仅仅利用了角度域的互易性。而且在为数不多的利用时延域互易性的方案中，并没有考虑终端侧的定时偏差。定时偏差主要来源于两个方面，一是传输时延，定时提前(Timing Advance)的估计只能保证主径落在CP内，但是不能保证对准某个准确的采样点，如：第0个。二是UE接收的时候，通常会提前几个采样点开窗，这取决于终端的具体实 现，并且不为网络侧所知。
因此，上述两种方法均会受到终端侧定时的影响。对于方法一，网络指示的各个径的时延并不是终端侧所期望的径(比如强度最大)的时延。同样地，对于方法二，网络在进行频率选择性预编码时也会造成所选径不是终端所期望的径(比如强度最大)。显然，这样会导致终端侧上报的相位并不是网络侧希望的相位，从而导致网络侧对下行信道的冲激响应估计不准确，影响下行预编码矩阵的计算和推导，从而降低下行传输的吞吐量。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的参考信号的调整方法进行详细地说明。
本申请实施提供了一种参考信号的调整方法，该方法由终端执行，图2是本申请实施例的参考信号的调整方法的流程图一，如图2所示，该方法的步骤包括：
步骤S202，获取第一信息；
步骤S204，根据第一信息执行第一操作；其中，第一操作包括如下至少一项：调整接收到的第一参考信号的接收时间；对第一参考信号的计算结果进行时域或频域的补偿；确定是否执行定时校准。
通过本申请实施例中的步骤S202和步骤S204，如果出现了网络对参考信号的指示和终端侧对参考信号的测量结果不匹配的情况，终端可以根据第一信息调整接收到的第一参考信号的接收时间，或对第一参考信号的计算结果进行时域或频域的补偿，以使网络对参考信号的指示和终端侧对参考信号的测量结果匹配；还是在沿用之前已经执行过的定时校准对参考信号进行调整，或者是当前信道状态发生变化，之前定时校准的参数已经不能再使用则需要重新进行定时校准，然后对参考信号进行调整。也就是说，通过上述本申请实施例中的方式，可以对参考信号进行调整以使网络对参考信号的指示和终端侧对参考信号的测量结果匹配，从而解决了现有技术中网络对参考信号的指示和终端侧对参考信号的测量结果不匹配导致下行传输的吞吐量降低的问题，达到了提高下行传输的吞吐量的效果。
在本申请实施例的可选实施方式中，本申请实施例中的第一信息用于指示准共址(Quasi Co-Location，QCL)关系，第一参考信号和第二参考信号满 足QCL关系，执行定时校准包括：
步骤S11，在QCL关系下，对第二参考信号进行测量，并从测量结果中选择出满足预设条件的第一时延径；
步骤S12，确定第二时延径的位置与第一时延径的位置之间的偏差值；其中，第二时延径满足预设条件，第二时延径的位置由网络侧配置或者由协议约定。
可见，本申请实施例中的执行定时校准的目的是为了得到该偏差值，但是在某些情况下，可以复用之前测量得到的偏差值，即虽然网络对参考信号的指示和终端侧对参考信号的测量结果不匹配，但是信道状态一直比较稳定，即一段时间内的偏差都是比较稳定，则此时可以沿用之前的偏差值；也就是说，这种情况下不需要执行定时校准。只有当网络对参考信号的指示和终端侧对参考信号的测量结果不匹配，且信道状态一直都是比较波动的情况，则此时需要得到进行测量得到偏差值，以用重新测量得到的偏差值对参考信号进行调整。
在本申请实施例中，对偏差值计算的操作为周期性执行的，或由网络侧设备触发执行。其中，周期通过以下至少之一的方式确定：由协议约定、由网络侧设备指示、复用第二参考信号的测量周期。
在本申请实施例的其他可选实施方式中，对偏差值计算的操作也可以是非周期的。如果是周期性的，该周期可以是独立周期，由协议规定或者网络侧指示；又或者是该周期可以复用之前测量参考信号的周期，如，使用TRS作为QCL resource进行测量，当配置了目标协议的增强，每次TRS测量的时候，进行定时偏差测量。如果是非周期的，可以通过下行控制信息(Downlink Control Information，DCI)或MAC控制单元(MAC Control Element，MAC CE)或者无线资源控制(Radio Resource Control，RRC)等信令触发。
在本申请实施例的可选实施方式中，满足预设条件的第一时延径或第二时延径包括以下至少一项：时域幅度最大的时延径、时域幅度增速最大的时延径、由协议约定的时延径、由网络侧设备指示的时延径。
其中，时域幅度最大的时延径，或时域幅度增速最大的时延径，通俗来讲就是在对参考信号进行测量后，测量结果中时域幅度最大的时延径，或时 域幅度增速最大的时延径。而由协议约定的时延径、由网络侧设备指示的时延径，也可以是时域幅度最大的时延径，或时域幅度增速最大的时延径，也可以是其他特定的时延径。
需要说明的是，在本申请实施例中第一参考信号可以是CSI-RS，第二参考信号可以是CSI-RS也可以是追踪参考信号(Tracking Reference Signal，TRS)。当然，上述仅仅是第一参考信号和第二参考信号在本申请中的举例，第一参考信号和第二参考信号还可以是其他参考信号，例如解调参考信号(Demodulation Reference Signal，DMRS)。
此外，本申请实施例中的参考信号(第一参考信号、第二参考信号)可以是经过预编码的，也可以是没有经过预编码的；其中，预编码的方式包括：空间预编码和/或频率选择性预编码。但在本申请实施例中，参考信号如果是CSI-RS，可以复用正常的CSI测量使用的CSI-RS，可以节约资源的利用。
在第一参考信号为CSI-RS，第二参考信号为TRS的情况下，两者之间的QCL关系可以通过以下方式实现：由网络侧设备事先配置了某个TRS作为CSI-RS的QCL resource，当配置了目标协议中的CSI增强的时候，终端根据这个TRS的测量结果调整CSI-RS的接收；还可以是网络侧设备直接指示一个TRS作为CSI-RS的定时测量的QCL资源。在本申请实施例的可选实施方式中，网络侧设备可以指示一个TRS对应一个或多个CSI-RS端口，还可以是网络侧设备可以指示一个TRS resource或者其中的一个或多个端口。
在第一参考信号为CSI-RS，第二参考信号也是CSI-RS的情况下，两者之间的QCL关系可以通过以下方式实现：复用CSI-RS来指示QCL关系；网络侧设备指示一个或多个CSI-RS resource或者是其中的一个或多个端口，终端根据指示的内容在正常的CSI测量之外进行定时测量。
需要说明的是，本申请实施例中涉及到的QCL关系通过以下至少之一的方式确定：协议约定、网络侧设备指示。
在本申请实施例中的可选实施方式中，对于步骤S204中涉及到的调整参考信号的接收时间的方式，进一步可以包括：
步骤S21，根据偏差值确定开窗位置；
步骤S22，在开窗位置对第一参考信号进行测量。
其中，根据偏差至确定的开窗位置在实际应用场景中是指对下次接收到的第一参考信号进行测量需要提前或延后的开窗位置，如果第一时延径的位置比第二时延径的位置提前了，则延后该偏差值所对应的位置再对第一参考信号进行测量，如果第一时延径的位置比第二时延径的位置延后了，则提前该偏差值所对应的位置再对第一参考信号进行测量。
在本申请实施例中的另一个可选实施方式中，对于步骤S204中涉及到的对第一参考信号的计算结果进行时域或频域的补偿的方式，进一步可以包括：
步骤S31，根据偏差值计算第一参考信号的频域补偿系数；根据补偿系数对接收的第一参考信号的信道估计结果进行相位补偿，或，根据补偿系数对接收的第一参考信号进行信道估计后，并进行信道质量计算的计算结果进行相位补偿；
步骤S32，根据所偏差值对接收的第一参考信号的时延信息进行时延补偿。
对于上述步骤S31和步骤S32，在具体应用场景中，根据偏差值和第一参考信号占据的子载波数N，计算SD-CDD矩阵，时延就是所述偏差值；假设一个CSI-RS符号(一个QPSK符号)可以表示为x k，k为其对应的子载波映射位置，那么其对应的频域补偿系数为
Figure PCTCN2021123821-appb-000003
其中，
Figure PCTCN2021123821-appb-000004
为虚数单位。如果是对信道估计的结果进行补偿，就是
Figure PCTCN2021123821-appb-000005
如果是对信道质量计算的结果进行补偿，就是先根据x k计算预编码系数v k，然后乘以补偿系数
Figure PCTCN2021123821-appb-000006
在本申请实施例的可选实施方式中，在执行定时校准之后，本申请实施例的方法步骤还可以包括：
步骤S206，向网络侧设备上报定时校准所需的信道状态信息CSI处理单元(CSI Processing Unit，CPU)数量或CSI处理单元的工作时长。
其中，终端上报偏差值计算的CPU信息，因为偏差值计算可能和正常的CSI计算或者参考信号的其他行为同时进行，需要考虑是占用新的CPU还是同一个CPU串行进行，终端上报给网络侧设备所需要的CPU数量或者CPU 需要连续工作的时间，以辅助基站进行其他操作。
上面是从终端侧对本申请进行解释说明，下面将结合网络侧对本申请进行接收说明；
本申请实施例提供了一种参考信号的调整方法，该方法由网络侧设备执行，图3是本申请实施例的参考信号的调整方法流程图二，如图3所示，该方法的步骤包括：
步骤S302，向终端发送第一信息和参考信号。
可选地，该方法还可以包括步骤S304，确定第一信息，其中，该第一信息用于指示准共址QCL关系，第一参考信号和第二参考信号满足QCL关系，在QCL关系下，对第二参考信号进行测量，并从测量结果中选择出满足预设条件的第一时延径；
基于此，本申请实施例中的参考信号包括以下至少之一：第一参考信号、第二参考信号；其中，第二参考信号与第一参考信号的资源或端口满足QCL关系。
在本申请实施例中，该第二参考信号可以由网络侧设备配置，且数量为一个或多个；一个第二参考信号对应于一个或多个第一参考信号。
在本申请实施例中第一参考信号可以是CSI-RS，第二参考信号可以是CSI-RS也可以是追踪参考信号(Tracking Reference Signal，TRS)。当然，上述仅仅是第一参考信号和第二参考信号在本申请中的举例，第一参考信号和第二参考信号还可以是其他参考信号，例如解调参考信号(Demodulation Reference Signal，DMRS)。
本申请实施例中的方法步骤还可以包括：
步骤S306，接收所终端上报的中央处理器CPU数量或所述CPU的工作时长，其中，所述CPU数量或所述CPU的工作时长为定时校准所需的。
也就是说，上述网络侧设备向终端发送的第一信息和参考信号是用于终端在需要进行定时校准，或需要对参考信号进行调整时所需要的。

步骤S401，网络侧设备配置UE在port0上进行测量，指示UE最强径的位置为τ 1，并且发送CSI-RS；其中，该CSI-RS可以是经过空间域预编码的，也可以是没有经过空间域预编码的。
可选地，CSI-RS经过频率选择性预编码，且频率选择性预编码对应的时延为与上行信道冲激响应最强径的时延；该上行信道冲激响应由网络根据终端发送的SRS测量获得；终端发送的SRS可以是经过空间域预编码的，也可以是没有经过空间域预编码的。
步骤S402，终端在port0进行信道估计，从而获得下行信道的冲激响应。
步骤S403，终端寻找下行冲激响应中强度最大的径的时延为τ 2，并计算和时延τ 1的偏差值2。
步骤S404，UE在下次接收CSI-RS的时候，提前相应的偏差值(τ 1-τ 2)个采样点)开窗，保证最强径落在时延τ 1的位置。
可选实施方式2：
在该可选实施方式中，图5是本申请实施例中终端根据网络配置的CSI-RS进行信道估计得到的下行信道的冲激响应的幅值的示意图二，结合图5，本申请实施例中的调整参考信号的方法步骤包括：
步骤S501，网络配置UE在port0上进行测量，指示UE最强径的位置为τ 0，并且发送CSI-RS，其中，CSI-RS是经过空间域预编码的；
步骤S502，网络侧指示UE需要上报的时延位置为τ 0，τ 1，τ 2；
步骤S503，终端在port0进行信道估计，从而获得下行信道的冲激响应；
步骤S504，终端寻找下行冲激响应中强度最大的径的时延τ；
步骤S505，UE计算时延为τ，τ-τ 0+τ 1，τ-τ 0+τ 2的三条径对应的幅度和相位，量化之后上报给网络。
可选实施方式3：
在该可选实施方式中，本申请实施例中的调整参考信号的方法步骤包括：
首先，网络配置UE在port0上进行测量，指示UE最强径的位置为τ 0，并且发送CSI-RS，所述CSI-RS是经过空频联合预编码的，每个端口上映射 三个空频正交基。
步骤S601，网络侧指示UE需要上报的时延位置为τ 0，τ 1，τ 2；
步骤S602，终端在port0进行信道估计，从而获得下行信道的冲激响应；
步骤S603，终端在τ 0附近寻找下行冲激响应中强度最大的径的时延τ；
步骤S604，UE计算时延偏差τ-τ 0对应的频域选择预编码矩阵；

Figure PCTCN2021123821-appb-000007
其中，
Figure PCTCN2021123821-appb-000008
为虚数单位；N为DFT点数(如CSI-RS个数)。
步骤S605，UE在每一个端口处，对每个CSI-RS估计的结果，经过偏差补偿频率选择性预编码之后的结果作为最终结果，去计算PMI并上报。
可选实施方式4：
在该可选实施方式中，网络侧设备选择强度最大的端口或者空频正交基指示给终端进行定时校准，当网络侧设备发现信道质量发生变化，需要更改测量端口和/或最强径位置的时候，通过MAC CE或者RRC或者DCI等信令指示终端更换测量端口。
网络侧设备根据SRS估计上行信道，计算CSI-RS的预编码；其中，这个预编码可以是空间预编码，也可以是空频预编码，网络侧在所有的端口中选择最强的端口指示给终端。例如，网络侧设备根据接收到的上行信道，计算每个CSI-RS端口或者每个空频预编码正交基对应的编码后的频域结果的强度，选择强度最大的端口或者空频正交基指示给终端，这个强度可以是根据二阶矩计算，也可以根据一阶矩计算。
例如，设网络侧某个端口p的每个CSI-RS的预编码为w k,l,p，其中k表示子载波或者物理资源块(Physical Resource Block，PRB)，l表示端口，网络侧根据之前的CSI上报结果得到的下行信道或者根据SRS估计的下行信道在每个CSI-RS处的信道系数为h k,l，则这个端口p的二阶矩表示为
Figure PCTCN2021123821-appb-000009
这个端口p的强度也可以用一阶矩表示为
Figure PCTCN2021123821-appb-000010
当信道质量发生变化，强度最大的端口不再是之前的端口或者最强径的位置发生变化时，网络侧计算新的端口或者空频正交基，和/或最强径位置，通过MAC CE或者RRC或者DCI等信令指示终端。
终端到达定时测量的周期的时候，根据网络侧设备指示的新的端口和/或最强径位置，重新计算偏差值；或者，网络侧设备通过DCI/MAC CE/RRC等信令触发终端根据最新指示的端口和/或最强径位置重新计算偏差值。
可选实施方式5：
在该可选实施方式中，网络侧设备事先为CSI-RS配置了一个TRS作为QCL resource；正常情况下，终端根据TRS进行定时，当配置了目标协议中相关的增强信息，终端在TRS定时的同时，计算定时偏差，或者根据网络侧设备的触发进行测量，进而根据测量结果调整估计CSI-RS的开窗时间。
网络侧设备可以针对每个CSI-RS端口指示一个TRS作为QCL resource，这些QCL resource可以部分相同，UE在指定的资源位置测量定时偏差，在不同的CSI-RS端口接收的时候，分别调整开窗位置，或者对接收的结果进行相位补偿。
通过上述可选实施方式1至5，网络侧设备可以指示终端进行定时校准的资源(端口或端口的一部分)，终端周期或非周期(由网络侧触发)进行定时校准，进而终端根据定时校准的结果，调整网络指示的CSI上报时延，以及终端向网络报告定时校准所需要的CPU数目或者持续时长。终端通过网络侧设备指示的信息进行定时校准，可以抑制定时偏差带来的性能损失，提高CSI测量精度，同时终端上报定时偏差检测所需的时间，可以帮助网络侧设备进行调度。
