作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。

应理解，在用于蜂窝通信的无线终端的内部，会产生各种各样的自干扰信号：也就是终端内部产生/发出的信号，会干扰终端正常的接收。
在本申请的一些实施例中，可以根据自干扰信号的来源，将其分为三类。
其中，第一类自干扰信号可以是由通信系统的一个或几个发射信号产生的谐波或互调干扰。例如，可以是由蜂窝通信系统的一个或几个发射信号产生的谐波或互调干扰。
第二类自干扰信号来源于手机内部不同的无线通信模块之间的干扰，例如，无线保真(Wireless-Fidelity，WiFi)信号和蜂窝信号之间的干扰。
第三类自干扰信号主要源于终端内部的一些有源电子器件产生的电磁波。例如，终端设备的显示屏、终端设备的内存读取操作、终端设备的相机和电动马达等器件产生的电磁波。所述电磁波的频率范围可以为几十MHz至几百MHz，当其谐波落在蜂窝频段上，或其谐波与蜂窝频段的发射信号产生互调时，所述电磁波会对蜂窝频段的接收产生干扰。
本申请实施例中，终端设备在进行自干扰消除校准和自干扰消除的效果的上报时，可以是针对上述第一类自干扰信号、第二类自干扰信号以及第三类自干扰信号中的至少一种。如，在针对上述第一类自干扰信号时，终端设备针对第一类自干扰信号进行自干扰消除校准和自干扰消除的效果的上报。
具体地，假设载波F1工作在低频段，载波F2工作在高频段，那么可能会有三种不同类型的互干扰存在：
类型一，F1的上行载波和F2的上行载波的某一阶互调信号(intermodulation，IM)的频率与某载波F3的下行信号频率重叠或部分重叠。那么载波F1和载波F2就对载波F3构成了干扰。载波F3可能是载波F1或载波F2中某一个，或是不同于载波F1与载波F2的另一个载波(此时终端可能同时工作在两个以上的载波)。一个例子是一个终端设备同时配置了频段(band)1和band 7的LTE载波，以及NR载波(3400-3800MHz)，则如果band 7的上行链路(Uplink，UL)和NR的UL同时传输，其产生的5阶互调影响会影响band 1的下行链路(Downlink，DL)接收机灵敏度。
类型二，F1的上行载波的倍频与F2的下行信号频率重叠或部分重叠。那么载波F1对F2就构成了谐波(harmonic)干扰。例如：LTE Band 3的上行1710-1785MHz，其2阶谐波范围为3420-3570MHz。则一个终端如果同时在band 3上进行LTE上行传输和在NR频段3400-3800MHz上进行DL接收，则2阶谐波可能会干扰NR的DL接收机的灵敏度。
类型三，F1的下行载波的倍频，与F2的上行信号频率(及其邻近频率)重叠或部分重叠。那么载波F2对F1就构成了谐波互调(harmonic mixing)干扰。例如：LTE Band 3的下行1805-1880MHz，其2阶谐波范围为3610-3760MHz。则一个终端如果同时在band 3上进行LTE下行接收和在NR频段3400-3800MHz上进行上行发送，则NR的2阶谐波互调可能会干扰LTE的DL接收机的灵敏度。
终端侧自干扰消除的基本原理是：将发射信号耦合或采样出一部分后作为参考信号，再对参考信号施加相应的增益、延时和相位调节，构建与实际自干扰信号功率相等、相位相反的对消信号，最后在接收端实现自干扰信号的相消干涉消除。上述过程本质上是终端内部实现一个自干扰重建的模型。
由于自干扰消除技术很大程度上取决于终端实现，在实际通信过程中如何衡量自干扰消除的效果就很重要。在实际通信过程中，需要为自干扰消除技术引入一个校准过程，校准过程的目的是为了获得自干扰消除的效果。由于自干扰消除的效果取决于很多其它因素，因此如何让网络设备获知自干扰消除的效果是个问题。基于这一问题，本申请实施例提供了一种终端设备上报自干扰消除的效果的方法，网络设备可以获知终端设备的自干扰消除的效果，从而可以准确掌握在一定的上行干扰信号强度下，当终端设备使用了自干扰消除技术后，下行信号所受干扰的程度，进而提升系统性能。
图2是根据本申请实施例的无线通信方法200的示意性流程图，如图2所示，该方法200可以包括如下内容：
S210，终端设备向网络设备发送第一信息，该第一信息用于指示该终端设备的自干扰消除的效果。
可选地，在本申请实施例中，该第一信息包括该终端设备在执行自干扰消除校准之后未被消除的干扰信号强度和/或该终端设备在执行自干扰消除校准之后测量得到的下行信号干扰噪声比(Signal to Interference plus Noise Ratio，SINR)。
可选地，在本申请实施例中，终端设备在不同类型的校准时段内执行自干扰消除校准之后，所得到的表征自干扰消除的效果的信息不同，即该第一信息也不同。
若该终端设备在第一类校准时段内进行自干扰消除校准，该第一信息包括该终端设备在执行自干扰消除校准之后未被消除的干扰信号强度；或者
若该终端设备在第二类校准时段内进行自干扰消除校准，该第一信息包括该终端设备在执行自干扰消除校准之后未被消除的干扰信号强度和/或该终端设备在执行自干扰消除校准之后测量得到的下行SINR。
可选地，在该第一类校准时段内仅存在干扰信号，在该第二类校准时段内存在干扰信号和已知的下行信号。
具体地，在第一类校准时段内，只有干扰信号而无下行接收信号。当终端设备已经进行自干扰消除时，那么在第一类校准时段中，进入终端设备接收机中的信号应当是没有被完全消除的干扰信号+接收机本身的背景噪声。由于终端设备接收机自己的背景噪声水平可以通过别的方式(已知的方式)测得，那么通过该第一类校准时段就可以得知没被消除的干扰信号的强度。终端设备可以向网络设备汇报没被消除的干扰信号的强度。由于上行干扰信号的强度是受网络设备调度控制的，收到终端设备的汇报以后，网络设备就能知道在一定的上行干扰信号强度下，当终端设备使用了自干扰消除技术后，下行信号所受干扰的程度。在某些情况下，网络设备可以向终端设备通知背景噪声强度，这往往是由于其它小区的下行信号或上行信号构成了较强的干扰，进而叠加进终端的背景噪声中，此时终端设备在计算没被消除的干扰信号的强度时，将使用网络设备通知的背景噪声强度或水平，一般以dBm(分贝毫瓦)为单位。
具体地，在第二类校准时段内，存在干扰信号和已知的下行信号。由于下行信号已知，终端设备可以评估或校准在有下行信号时的自干扰消除能力。由于下行信号已知，终端设备可以测量下行的SINR，进而判断干扰消除的效果是否符合预期。当终端设备向网络设备汇报测量得到的SINR后，网络设备就可以知道在一定的下行和上行发射功率下的终端的接收信号质量。
需要说明的是，由于终端设备接收机自己的背景噪声水平可以通过别的方式测得或通过网络设备的通知获得，对于第二类校准时段而言，也是可以通过信号处理的方法计算得到在第一类校准时段中得到的没被消除的干扰信号的强度。如果网络设备要求，终端设备也可以向网络设备汇报这一强度。需要指出的是，虽然对于第二类校准时段可以用信号处理的方式得出未被消除的干扰信号的强度，但可能不如在第一类校准时段下测量准确，因为第一类校准时段是终端设备直接在接收端测量得到，而第二类校准时段则需要作后期的信号处理。
可选地，作为实施例一，该终端设备接收网络设备发送的第一配置信息，该第一配置信息包括但不限于以下信息中的至少一种：
至少一个校准时段中的每个校准时段的类型，其中，该每个校准时段的类型为该第一类校准时段或该第二类校准时段；
至少一个校准时段中的每个校准时段的时长；
至少一个校准时段中的每个校准时段所针对的频段组合；
至少一个校准时段中的每个校准时段所针对的干扰类型；
至少一个校准时段中的每个校准时段所针对的干扰信号的强度。
可选地，在该第一配置信息中，该每个校准时段的时长包括至少一个符号(symbol)。
可选地，在该第一配置信息中，该每个校准时段所针对的频段组合包括至少一个用于上行发送的频段与至少一个用于下行接收的频段的组合。譬如B3(1.8G)+n78(3.5G)，B8(0.9G)+B3(1.8G)。
应理解，B3是指band 3(频段3)，同理，B8是指band 8，n78是指NR频段78。
可选地，在该第一配置信息中，该每个校准时段所针对的干扰类型包括谐波干扰和/或互调干扰。对于某个特定的频段组合，可以存在不止一种干扰，此时需要明确校准时段是针对哪种干扰的，譬如上述B3(1.8G)+n78(3.5G)，存在谐波和互调干扰，所以需要指出校准时段所针对的干扰种类，是单独的谐波干扰，还是单独的互调干扰。当网络设备指出针对校准时段的特定干扰类型时，在此校准时段中，网络设备也会调度引起特定干扰类型的上行信号发射。
需要说明的是，干扰类型这一参数，应当是频段组合参数下的一个子参数。
可选地，在该第一配置信息中，
若干扰类型为谐波干扰，则干扰信号的强度为引起谐波的发射信号的强度；
若干扰类型为互调干扰，则干扰信号的强度为引起互调的两路上行信号分别的强度；
若干扰类型为谐波干扰和互调干扰，则干扰信号的强度为引起干扰的每一路上行信号分别的强度。
具体地，在该实施例一中，该终端设备根据该第一配置信息在该至少一个校准时段内分别进行自干扰消除校准。
需要说明的是，在该实施例一中，对某些特定的频带组合，可能存在多种干扰，譬如：B3(1.8G)+n78(3.5G)，就存在互调和谐波干扰，为了终端设备能更精确的测得互调和谐波干扰，网络设备可以分别调度校准时段：譬如两个校准时段，一个校准谐波干扰，另一个校准互调干扰。当校准谐波干扰时，只有B3的发射信号；当校准互调干扰时，同时有B3和n78的发射信号。当然也可以有一个校准时段，同时校准谐波和互调干扰。此时，网络设备在调度校准时段时，必须向终端设备指出此校准时段所针对的校准干扰的类型。譬如，网络设备可以为B3+n78这个频段组合向终端设备就谐波和互调干扰各提供一个校准时段，每个校准时段的时长是一个符号，并且都是最大发射功率，也就是校准谐波干扰时，B3的发射功率是23dbm(假设是功率等级3的终端设备)，校准互调干扰时，B3和n78的发射功率各是20dbm。
可选地，在该实施例一中，每执行一次自干扰消除校准，该终端设备发送一次该第一信息，其中，该第一信息用于指示当前校准时段内该终端设备的自干扰消除的效果。
可选地，作为实施例二，该终端设备接收网络设备发送的第二配置信息，该第二配置信息用于配置校准时间单元，该校准时间单元包括但不限于以下信息中的至少一种：
多个校准时段中的每个校准时段的类型，其中，该每个校准时段的类型为该第一类校准时段或该第二类校准时段；
多个校准时段中的每个校准时段的时长；
多个校准时段中的每个校准时段所针对的频段组合；
多个校准时段中的每个校准时段所针对的干扰类型；
多个校准时段中的每个校准时段所针对的干扰信号的强度。
可选地，在该校准时间单元中，该每个校准时段的时长包括至少一个符号(symbol)。
可选地，在该校准时间单元中，该每个校准时段所针对的频段组合包括至少一个用于上行发送的频段与至少一个用于下行接收的频段的组合。譬如B3(1.8G)+n78(3.5G)，B8(0.9G)+B3(1.8G)。
可选地，在该校准时间单元中，该每个校准时段所针对的干扰类型包括谐波干扰和/或互调干扰。对于某个特定的频段组合，可以存在不止一种干扰，此时需要明确校准时段是针对哪种干扰的，譬如上述B3(1.8G)+n78(3.5G)，存在谐波和互调干扰，所以需要指出校准时段所针对的干扰种类，是单独的谐波干扰，还是单独的互调干扰。当网络设备指出针对校准时段的特定干扰类型时，在此校准时段中，网络设备也会调度引起特定干扰类型的上行信号发射。
可选地，在该校准时间单元中，
若干扰类型为谐波干扰，则干扰信号的强度为引起谐波的发射信号的强度；
若干扰类型为互调干扰，则干扰信号的强度为引起互调的两路上行信号分别的强度；
若干扰类型为谐波干扰和互调干扰，则干扰信号的强度为引起干扰的每一路上行信号分别的强度。
可选地，在该校准时间单元中，该多个校准时段在时域上连续，且该校准时间单元为时域上连续的该多个校准时段构成的一个全下行的子帧结构。
例如，每个校准时段的时长都是1个符号，那么校准时间单元就可以认为是由时域连续的校准时段构成的全下行的一种子帧结构。即终端设备所作的校准都是在一个子帧内完成。
可选地，构成校准时间单元的校准时段的类型决定了有三种校准时间单元类型：
校准时间单元类型1：构成校准时间单元的校准时段全部是第一类校准时段；
校准时间单元类型2：构成校准时间单元的校准时段全部是第二类校准时段；
混合型校准时间单元：构成校准时间单元的校准时段中有第一类校准时段，也有第二类校准时段。
可选地，网络设备具体在配置校准时间单元的参数时，例如可以使用如下表1所示的二维数据组进行配置。
表1
Figure PCTCN2018124596-appb-000001
需要说明的是，上述表1中各参数均是可以配置的。
可选地，在该实施例二中，该终端设备根据该第二配置信息，在该多个校准时段内分别进行自干扰消除校准。
可选地，在该实施例二中，在该多个校准时段内都进行自干扰消除校准之后，该终端设备发送该第一信息，其中，该第一信息用于指示该多个校准时段中的每个校准时段内该终端设备的自干扰消除的效果。
假设该校准时间单元包括校准时段1至校准时段4，且校准时段1和校准时段2为第一类校准时段，校准时段3和校准时段4为第二类校准时段，则该第一信息可以是：
校准时段1，信号强度a；
校准时段2，信号强度b；
校准时段3，SINR a；
校准时段4，SINR b。
因此，终端设备可以第一信息中向网络设备上报多个校准时段内的自干扰消除的效果，避免了各自单独上报所造成的比较大的信令开销。
终端设备所受的实际背景干扰水平(非终端自干扰而带来的干扰)会随着终端设备所受调度、位置等因素的不同而发生变化，终端设备在不同校准时段上的校准结果，无法保证是在同一干扰水平下做出的，其结果可能会不准。因此，需要对该校准时间单元的参数统一配置。
可选地，在该实施例二中，网络设备可以通过该第二配置信息统一配置该校准时间单元的参数，以节约信令开销。
例如，该多个校准时段可以全部为该第一类校准时段或者该第二类校准时段。
又例如，该多个校准时段中的每个校准时段的时长相同。
再例如，该多个校准时段中的每个校准时段所针对的频段组合相同。
再例如，该多个校准时段中的每个校准时段所针对的干扰类型相同。
具体地，可以如下表2所示，在该校准时间单元中，该多个校准时段全部为该第一类校准时段，该多个校准时段中的每个校准时段所针对的频段组合为B3+n78，该多个校准时段中的每个校准时段所针对的干扰类型为互调，且该多个校准时段中的每个校准时段所针对的干扰信号的强度不同。
表2
Figure PCTCN2018124596-appb-000002
在上表2中，校准时间单元中的各个参数的相关配置都被列出，具体包括如下参数：
每一个校准时段的类型，每一个校准时段的频带组合，每一个校准时段所针对的干扰类型，以及每一个校准时段所针对的干扰信号的强度。
在上述表2中，校准时段类型、频带组合和干扰类型的参数相同，干扰强度呈现出等差分布，且公差为3。
需要指出的是，虽然每个校准时段的频带组合都是可配置的，但在实际情况下最可能出现的情况是一个校准时间单元只对应一种频带组合，以及只对应一种干扰类型，如上表2所示。这种情况下，频带组合/干扰类型可以统一配置，以节约信令开销。另外对于互调干扰，两路发射信号的功率需要分别指示。上表中两路发射信号功率是一样的，但在实际中有可能出现不一样的情况。
可选地，采用如上表2所示配置的校准时间单元，在该多个校准时段内都进行自干扰消除校准之后，该终端设备发送该第一信息，其中，该第一信息用于以第一校准时段为基准差分指示该多个校准时段中的每个校准时段内该终端设备的自干扰消除的效果，该第一校准时段属于该多个校准时段。
例如，该第一校准时段为校准时段1，该第一信息可以是：
校准时段1，信号强度a；
校准时段2，信号强度a-3；
校准时段3，信号强度a-6；
校准时段4，信号强度a-9。
需要说明的是，该第一校准时段为预配置的，或者为网络设备指示的。
例如，在该终端设备发送该第一信息之前，该终端设备还可以接收网络设备发送的第一指示信息，所述第一指示信息用于指示所述终端设备以所述第一校准时段为基准差分上报所述多个校准时段中的每个校准时段内所述终端设备的自干扰消除的效果。
具体地，采用如上表2所示配置的校准时间单元的一个好处是，终端设备可以通过这个校准时间单元，得到在某个频带组合下某种类型的干扰在不同发射功率情况下对接收机的干扰程度。由于终端设备所做的校准都是在一个子帧内完成的，其校准条件可以认为是基本相同的。如上表2所示的配置，网络设备在配置终端设备汇报校准结果时(自干扰消除的效果，或者接收机所受的干扰水平)，可以指定以其中某一个校准时段为基准作差分汇报。譬如，在表2中，校准时段4对应的未被消除的干扰信号的强度为3dBm，则校准时段3/2/1对应的未被消除的干扰信号的强度就是校准时段4对应的未被消除的干扰信号的强度的差分值，譬如校准时段3/2/1分别为：6dBm，9dBm，12dBm。假如网络设备对各个校准时段的干扰功率的配置是按升序或降序排列，终端设备在汇报干扰水平时可以进一步按照依次差分去汇报，以进一步压缩信令开销。仍然以上表2为例，以校准时段4的干扰水平作为基准，校准时段3的汇报值是与校准时段4的值的差分，依次类推，校准时段2的汇报值是与校准时段3的值的差分，校准时段1的汇报值是与校准时段2的值的差分。此时，对校准时段3/2/1对应的未被消除的干扰信号的强度的汇报的差分值分别为：3，3，3。
因此，在本申请实施例中，终端设备在进行自干扰消除校准之后，可以向网络设备上报自干扰消除的效果，从而网络设备可以准确掌握在一定的上行干扰信号强度下，当终端设备使用了自干扰消除技术后，下行信号所受干扰的程度，进而提升系统性能。
进一步地，网络设备可以配置校准时间单元，从而终端设备可以第一信息中向网络设备上报多个校准时段内的自干扰消除的效果，避免了各自单独上报所造成的比较大的信令开销。
更进一步地，终端设备可以以第一校准时段为基准差分指示多个校准时段中的每个校准时段内终端设备的自干扰消除的效果，以进一步压缩信令开销。
