为便于理解本申请实施例的技术方案，对本申请相关的MIMO计算进行说明。
对于具有多个发射天线的终端设备来说，上行可支持MIMO多流传输。上行MIMO包括基于码本的MIMO传输和不基于码本的MIMO传输。对于基于码本的MIMO传输来说，码本通常分为全相关(full coherent)码本、部分相关(partial coherent)码本、不相关(non-coherent)码本。或者说，基于码本的MIMO传输可以包括全相关MIMO传输，部分相关MIMO传输和不相关MIMO传输。
表1是具有两个发射天线的终端设备可配置的码本示例，其中，传输预编码矩阵指示(Transmission Precoding Matrix Indicator，TPMI)0和1为不相关码本，TPMI 2/3/4/5为全相关码本。该终端设备通常只能支持上行2流传输，从码本表格中可以看到对于这类终端设备来说只能工作在不相关码本或全相关码本两种状态。当终端设备支持的上行MIMO流数高于2流时，可能会工作在部 分相关MIMO传输模式。
表1

终端设备的MIMO传输相关性是基于对多个发射通路的信号间的相对相位偏差以及相对功率(或者说，相对幅度)偏差来进行衡量的。全相关码本传输要求终端设备能够在一定时间内保持多个发射通路间的功率及相位的相对变化能够控制在一定范围内，从而可以采用全相关码本进行更高效的MIMO传输。网络设备可以根据终端设备的MIMO传输能力来给终端设备配置对应类型的码本，例如全相关(full coherent)码本、部分相关(partial coherent)码本还是不相关(non-coherent)码本。
在一些场景中，终端设备会在初始时刻(例如随机接入时)上报其MIMO传输能力，也即支持的码本类型是全相关(full coherent)码本还是部分相关(partial coherent)码本还是不相关(non-coherent)码本。该支持的码本类型将在后续通信过程中保持不变。
如图2所示，若终端设备有两个发射通路，则MIMO传输相关性主要是指发射通路1和发射通路2的信号间的相对幅度及相对相位的偏差。而影响终端设备的MIMO传输相关性的因素有很多，例如高温、低温、高电压、低电压等，由于终端设备需要保证在所有的场景下其MIMO传输相关性都是相同的，导致了终端设备即使在部分情况下是能够支持全相关或部分相关传输的也只能上报具有不相关MIMO传输能力。此外，终端设备内部的多个发射支路间的幅度或相位偏差会随着时间进行累积，最终导致偏差超过相关或部分相关的MIMO传输要求而只能适用不相关MIMO传输。
因此，终端设备难以保持全相关MIMO传输能力，这也导致了大部分终端都不具备全相关MIMO传输能力，影响了终端设备的性能，因此，如何保持终端设备的相关MIMO传输能力以提升终端设备的性能是一项急需解决的问题。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
图3是根据本申请实施例的无线通信的方法200的示意性交互图，如图3所示，该方法200包括如下内容：
S210，终端设备在第一校准窗口中，对所述终端设备的多个发射通路间的相关性进行校准；
S220，所述终端设备基于校准后的所述多个发射通路的相关性进行数据传输。
在本申请一些实施例中，所述终端设备的MIMO传输相关性可以包括不相关MIMO传输，部分相关MIMO传输和全相关MIMO传输，在其他实施例中，也可以包括更多种相关性等级，本申请仅以上述三种等级为例进行说明，但本申请并不限于此。
在本申请一些实施例中，不相关MIMO传输可以指基于不相关MIMO传输配置进行数据传输，部分相关MIMO传输可以指基于部分相关MIMO传输配置进行数据传输，全相关MIMO传输可以指基于全相关MIMO传输配置进行数据传输。
可选地，所述不相关MIMO传输配置可以包括不相关码本(或者说，码本集)，所述部分相关MIMO传输配置可以包括部分相关码本(或者说，码本集)，所述全相关MIMO传输配置可以包括全相关码本(或者说，码本集)。
应理解，在本申请实施例中，若终端设备指示支持部分相关码本集，则终端设备应该能够支持非相关码本集，若终端设备支持全相关码本集，则终端设备应该支持部分相关和不相关码本集。换言之，若终端设备支持全相关MIMO传输，则终端设备也支持部分相关MIMO传输和不相关MIMO传输，或者，若终端设备支持部分相关MIMO传输，则终端设备也支持不相关MIMO传输。
在本申请实施例中，所述终端设备通过对多个发射通路间的相关性进行校准使得所述多个发射通路的信号间的相对幅度以及相对相位变化量在一定范围内，从而满足相关MIMO传输的要求，进一步可以基于相关MIMO传输模式进行数据传输，提升终端设备的上行传输性能。
可选地，在一些实施例中，所述终端设备可以向网络设备上报初始MIMO传输能力，例如，该初始MIMO传输能力可以为全相关MIMO传输能力，部分相关MIMO传输能力或不相关MIMO传输能力等。或者说，终端设备可以向网络设备上报终端设备支持的码本类型，例如，全相关码本，部分相关码本或不相关码本等。
在一些场景中，由于终端设备无法保证在所有场景中的MIMO传输能力是相同的，导致即使终端设备在部分情况下能够支持全相关MIMO传输或部分相关MIMO传输，也只能上报具有不相关MIMO传输能力。
在本申请一些实施例中，通过对所述多个发射通路间的相关性进行校准提升了该多个发射通路间的相关性。例如，若校准前的该多个发射通路间的相关性为不相关，校准后的该多个发射通路间的相关性可以为部分相关或全相关。又例如，若校准前的该多个发射通路间的相关性为部分相关，校准后的该多个发射通路间的相关性可以为全相关。
应理解，在本申请实施例中，所述多个发射通路间的相关性可以根据该多个发射通路的信号间的相对相位变化量和相对幅度变化量确定。
在本申请一些实施例中，所述对所述终端设备的多个发射通路间的相关性进行校准可以指：对多个发射通路的信号的幅度和相位进行调整以使得所述多个发射通路的信号间的相对幅度和相对相位的变化量在目标范围内。
在一些实施例中，全相关码本传输要求终端设备能够在一定时间内保持多个发射通路的信号间的相对幅度及相对相位的变化量控制在第一范围内，部分相关码本传输也要求终端设备能够在一定时间内保持多个发射通路的信号间的相对幅度及相对相位的变化量控制在第二范围内。
可选地，所述目标范围可以为全相关码本所要求的第一范围，或者也可以是部分相关码本所要求的第二范围，具体可以根据终端设备的初始MIMO传输能力决定。
图4是以两个发射通路示例的终端设备的校准过程示意图。具体地，该终端设备可以包括控制单元(可以为终端设备的基带部分)、两个发射通路分别对应的功率放大器(PA)即PA1和PA2，以及混频器用于接收校准信号和本振信号(LO)，以及幅度和相位比较单元，用于对两个发射通路的信号的相对幅度和相对相位进行比较。
终端设备对发射通路的校准过程可以是：首先控制单元控制在目标频段上发射校准信号，将该校准信号输入至发射通路1和发射通路2，对该发射通路1和发射通路2输出端信号的幅度和相位进行比较，得到信号间的幅度偏差值和相位偏差值，将该幅度偏差值和相位偏差值输入至控制单元，用于调整发射通路发射的信号的幅度和相位以使得两个发射通路的信号间的相对幅度和相对相位的变化量在目标范围内，从而满足相关MIMO传输的需求。
在一些实施例中，所述目标频段可以为终端设备的工作频段，或者也可以为终端设备上配置的其他频段，例如，毫米波频段等，本申请对此不作限定。
在一些实施例中，由于终端设备需要在网络设备的调度下才能进行信号的发射以避免对其他用户的干扰。在本申请实施例中，通过网络设备给终端设备配置一个校准窗口，在该校准窗口中终端设备执行该多个发射通路间的相关性校准，或称，MIMO自校准。
可选地，终端设备在第一校准窗口中执行多个通路间的相关性校准时，终端设备和网络设备之间暂停正常的数据传输。例如，网络设备不在该第一校准窗口中调度该网络设备进行上行传输，终端设备在该第一校准窗口中不向网络设备发送上行信号。
在本申请一些实施例中，所述第一校准窗口是网络设备基于终端设备的校准窗口请求配置的。例如，在所述多个发射通路间的相关性低于预设条件的情况下，所述终端设备向网络设备请求配置该第一校准窗口。
在一些实施例中，终端设备可以监测该多个发射链路的信号间的相对幅度和相对相位的变化情况，当该多个发射通路间的信号的相对幅度变化量大于第一阈值，和/或该多个发射通路间的信号的相对相位变化量大于第二阈值的情况下，所述终端设备向网络设备请求配置该第一校准窗口。
可选地，在一些实施例中，所述校准窗口请求可以通过用于终端设备和网络设备之间交互的任一消息承载，例如，上行无线资源控制(Radio Resource Control，RRC)消息，上行媒体接入控制(Media Access Control，MAC)信令等。
在本申请另一些实施例中，所述第一校准窗口是网络设备自主给终端设备配置的，例如网络设备可以在相关MIMO传输的性能变差的情况下，给终端设备配置该第一校准窗口。可选地，所述相关MIMO传输的性能变差例如可以包括但不限于相关MIMO传输的吞吐量小于一定门限。
在本申请又一些实施例中，所述第一校准窗口可以是周期性的时间窗口。此情况下，所述终端设备可以不向网络设备发送校准窗口请求，在校准窗口的周期到来的情况下，终端设备和网络设备均知道终端设备会在接下来的一定时间内进行多个发射通路间的相关性校准，从而在该一定时间内暂停二者之间的正常的数据传输。
应理解，上述所述第一校准窗口的配置方式仅为示例，在其他实施例中，终端设备也可以在其他有MIMO自校准需求的情况下基于所述第一校准窗口进行MIMO自校准，本申请并不限于此。
在一些实施例中，所述网络设备可以给终端设备配置第一定时器(或称，阻止定时器)，其中，在所述第一定时器运行期间，禁止所述终端设备发起校准窗口请求，或禁止所述终端设备停止正在进行的相关性校准。
在一些实施例中，在所述第一定时器不工作的情况下，所述终端设备向所述网络设备发送所述校准窗口请求。
换言之，在所述第一定时器工作的情况下，在所述第一校准窗口内，所述终端设备不向所述网络设备再次发起校准窗口请求，或者不停止执行正在执行的相关性校准。
在本申请一些实施例中，所述方法200还包括：

在本申请另一些实施例中，在所述终端设备的初始MIMO传输能力为部分相关MIMO传输能力，并且期望采用(或者，保持采用)相关MIMO传输模式(例如部分相关MIMO传输模式或全相关MIMO传输模式)进行数据传输的情况下，基于校准窗口对所述终端设备的多个发射通路间的相关性进行校准。例如向网络设备发送所述校准窗口请求。
在本申请又一些实施例中，在所述终端设备的初始MIMO传输能力为全相关MIMO传输能力，并且期望采用(或者，保持采用)全相关MIMO传输模式进行数据传输的情况下，基于校准窗口对所述终端设备的多个发射通路间的相关性进行校准。例如向网络设备发送所述校准窗口请求。
可选地，在一些实施例中，所述网络设备还可以给终端设备配置校准信号的发射功率限制。即在所述第一校准窗口中发送的校准信号的最大发射功率。通过配置发射功率限制，能够降低终端设备在进行相关性校准时对其他UE的干扰。
在本申请一些实施例中，如图5所示，所述第一校准窗口为非周期性的时间窗口。所述终端设备在第一校准窗口内执行多个发射通路间的相关性校准，在其他时间执行正常的数据通信。
在一些实施例中，所述第一校准窗口的长度是预定义的。
换言之，所述第一校准窗口的长度可以是固定时间长度，此情况下，终端设备只需要向网络设备发出校准窗口请求，网络设备按照固定时间长度来配置该校准窗口即可。
在另一些实施例中，所述第一校准窗口的长度是网络设备配置的。
在一些实施例中，所述第一校准窗口的长度可以是网络设备基于终端设备的请求配置的，例如所述校准窗口请求用于请求配置该第一校准窗口的同时，还可以用于请求所述网络设备配置所述第一校准窗口的长度。例如，所述校准窗口请求可以包括所述终端设备期望的第一校准窗口的长度。可选地，所述网络设备可以根据终端设备的能力或实现需求配置所述第一校准窗口的长度，或者，也可以配置终端设备期望的第一校准窗口的长度。
