应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独 存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
可选地，终端设备的发射机在发射信号时，如果接收机同时在接收信号，且终端设备发射的信号与接收的信号同频，则终端设备发射的信号会对终端设备接收的同频信号产生干扰，此种现象可以称为自干扰。
可选地，自干扰可以分为谐波干扰、谐波混频干扰和互调干扰三种类型。每种类型的自干扰还可以细分更小粒度的类型，例如，对于互调干扰而言，互调信号的阶数不同时，可以分为不同类型的干扰。例如，对于谐波干扰而言，谐波干扰时信号的倍频不同时，可以分为不同类型的干扰。
以下以终端设备同时工作在载波F1和载波F2进行举例说明自干扰的几种类型，其中，假设载波F1工作在低频段，载波F2工作在高频段。
在一种可能中，F1的上行载波和F2的上行载波的某阶互调信号(IM，intermodulation)的频率与载波F3的下行信号频率重叠或部分重叠。那么载波F1和F2就对F3构成了互调干扰。这里F3可能是载波F1或F2中某一个，或是不同于F1/F2的另一个载波(此时，终端设备同时工作在两个以上的载波)。
例如，终端设备同时配置了Band 1和Band 7的LTE载波，NR载波(3400-3800MHz)，则如果band 7的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DL接收机灵敏度。
在一种可能中，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。
在一种可能中，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就构成了谐波混频(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阶谐波混频可能会干 扰LTE的DL接收机的灵敏度。
为了尽量避免自干扰，本申请实施例提供了以下的方法和装置。
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。该方法200可选地可以应用于图1所示的系统，但并不限于此。该方法200可选地可以有终端设备执行。该方法200包括以下内容中的至少部分内容。
在210中，终端设备确定终端设备与网络设备进行通信的第一上行频段和第一下行频段对该终端设备产生的自干扰强度。
在一种实现方式中，终端设备可以根据预设列表，确定该第一上行频段和该第一下行频段对该终端设备产生的自干扰强度。
在另一种实现方式中，终端设备可以通过测量的方式，确定该第一上行频段和该第一下行频段对该终端设备产生的自干扰强度。
可选地，在本申请实施例中，该自干扰强度可以是：在利用第一上行频段发送上行信号时，在第一下行频段接收到的信号(不包括接收的来自外界的信号)的强度。
可选地，在本申请实施例中，该第一上行频段包括多个频段；和/或，该第一下行频段包括多个频段。
应理解，在本申请实施例中，第一上行频段和第一下行频段对所述终端设备产生自干扰意味着：终端设备在第一上行频段的全部或部分频率范围发送的信号对同时在第一下行频段的全部或部分频率范围接收的信号产生干扰。
在220中，终端设备向该网络设备发送第一消息，该第一消息用于表征该第一上行频段和该第一下行频段对该终端设备产生的自干扰强度。
可选地，该第一消息包括以下信息：该第一上行频段的信息；该第一下行频段的信息；和表征该自干扰强度的信息。
可选地，第一上行频段的信息可以包括该频段的起止频频，或包括该频段的起始频率和频段大小，或包括该频段的终止频率和频段大小。
可选地，第一下行频段的信息可以包括该频段的起止频频，或包括该频段的起始频率和频段大小，或包括该频段的终止频率和频段大小，
可选地，表征该自干扰强度的信息可以直接表征该自干扰强度，例如，该自干扰强度为在第一下行频段接收信号的强度，则直接将该自干扰强度上报给网络设备。
可选地，表征该自干扰强度的信息可以间接表征该自干扰强度，例如，可以借用基于参考信号获取的(Channel Quality Indication，CQI)来表征该自干扰强度。
可选地，该第一消息携带第一信道质量指示CQI，该第一CQI用于表征该第一下行频段和该第一上行频段对该终端设备产生的自干扰强度。
可选地，终端设备根据该网络设备利用该第一下行频率向该终端设备发送的参考信号，确定第二CQI；根据该第二CQI和确定的该自干扰强度，终端设备确定该第一CQI。其中，该第二CQI不用于表征自干扰强度，可选地与信号的调制编码方案(Modulation and Coding Scheme，MCS)有关。
具体地，由于自干扰会降低终端设备的下行接收性能，所以终端设备向网络设备的汇报也可以体现在终端设备对CQI的计算上，终端可以计算受干扰频段的信号强度/(噪声强度+自干扰强度)的比率，并将这个比率折算成CQI向网络汇报。
可选地，终端设备可以通过物理层信令向终端设备汇报该表征自干扰强度的CQI。
可选地，如果网络设备需要终端设备在某些频段的CQI汇报包含终端设备的自干扰，通过指示消息的某一字段来表示，例如，该字段取值为1表示汇报的CQI包含自干扰强度，字段取值为0表示汇报的CQI不包含自干扰强度。
可选地，终端设备向网络设备汇报的第一消息可以包括第一比特；在该第一比特取第一值(例如1)时，表征该第一消息携带的CQI为该第一CQI；在该第一比特取值为第二值(例如0)时，表征该第一消息的CQI为该第二CQI。
应理解，同时表征第二CQI和自干扰强度的信息也可以不被称为CQI，还可以有其他的叫法，只要实质与本申请的第二CQI一致，均在本申请的保护范围之内。
可选地，在本申请实施例中，该第一消息还用于指示该第一上行频段和该第一下行频段对该终端设备产生的自干扰的类型。
在一种实现方式中，该第一上行频段可以包括多个上行频段，该第一下行频段包括一个下行频段，此时，产生的干扰类型可以是互调干扰，其中，干扰的类型还可以按照产生干扰的互调信号的阶数进一步细分。
在一种实现方式中，该第一上行频段可以包括一个上行频段，该第一下行频段包括一个下行频段，此时，产生的干扰类型可以是谐波干扰或谐波混频干扰，其中，干扰的类型还可以按照对下行频段产生干扰的上行频段的倍频进行细分，或者还可以按照被该上行频段干扰的下行频段的倍频进行细分。
可选地，在本申请实施例中，第一上行频段和第一下行频段对该终端设备产生的自干扰强度还可以跟发射功率有关，则终端设备向网络上报的该自干扰强度可以是该终端设备在第一发射功率下的自干扰强度，该第一发射功率为该终端设备利用该第一上行频段向该网络设备发送信号的发射功率。
在该种实现方式中，该第一消息还包括用于指示该第一发射功率的信息。
可选地，在该第一上行频段包括多个频段时，可以包括在每个频段上分别发送上行信号的发射功率。其中，该多个频段上的发射功率可以相同，也可以不相同。
因此，在该种实现方式中，网络设备结合终端设备在特定发射功率下，第一上行频段和第一下行频段对终端设备产生的自干扰强度，对终端设备进行调度，例如，在该发射功率下，干扰强度较高，则可以降低终端设备的发射功率，或者避免调度终端设备在第一上行频段和第一下行频段同时进行信号收发；或者，在该发射功率下，干扰强度调度较低，则可以尝试升高终端设备的发射功率。
可选地，在本申请实施例中，终端设备可以采用多种方式，确定第一上行频段和下行频段对终端设备产生的自干扰强度。为了便于理解，以下将介绍两种实现方式。
在一种实现方式中，根据预设列表，终端设备确定该第一上行频段和该第一下行频段对该终端设备产生的自干扰强度。
可选地，由于自干扰是终端设备内部产生的，而一个终端设备在设计时，所支持的频段就已经知道，那么如果这些频段之间存在互干扰，这些互干扰严重程度也可以在终端设备的设计过程中就被测量获得，在终端被制造时就已经被预先设置在终端设备的内部。
可选地，终端设备也可以在制作完成后，依次测量各个频段组合下的自干扰强度，并预存储在终端设备上。
可选地，该预设列表包括至少一个产生自干扰的上行频段和下行频段的组合，以及该组合对应的自干扰强度。
可选地，第一上行频段和第一下行频段的组合可以是该至少一个组合中的任意一个组合。
其中，组合中的频段的信息可以包括上行频段的起止频率位置和下行频段的起止频率位置。
可选地，每个组合可以包括多个上行频段和/或多个下行频段，此时，则包括每个频段的起止频率。
可选地，该组合中的频段可以是终端设备支持的频段，频段划分的颗粒度可以根据实际情况而定，其中，产生自干扰的上行频段和下行频段的组合可以表示：该上行频段的全部或部分频率范围对该下行频段的全部或部分频率范围产生自干扰。
可选地，该预设列表还包括：该组合对应的自干扰的类型。
可选地，该组合中每个上行频带上发射信号分别采用多个发射功率时的自干扰强度。
可选地，在组合包括多个上行频带时，每个上行频带的发射功率可以不同，也可以相同，该预设列表可以指示每个上行频段的发射功率。
例如，对于互调干扰而言，则预设列表中可以预设每个上行载波上发送信号的发射功率。
可选地，在该终端设备进入该网络设备的网络覆盖范围之内时，或者接收到该网络设备的指示之后，该终端设备向该网络设备发送该第一消息。
具体地，在终端设备在进入该网络设备的覆盖范围之内时，可以自动上报预设列表中的信息。或者，接收到网络设备的指示后，按照网络设备的指示上报该预设列表中的信息(可以上报预设列表中的全部或部分信息)，其中，网络设备可以指示终端设备上报哪个频段组合下的自干扰强度，或者上报哪个频段组合在哪个发射功率下的自干扰强度。
在另一种实现方式中，通过测量，终端设备确定该第一上行频段和该第一下行频段对该终端设备产生的自干扰强度。
可选地，终端设备可以接收该网络设备发送的第一指示信息，该第一指示信息用于指示该终端设备测量和/或上报该第一上行频段和该第一下行频段对该终端设备产生的自干扰强度。
应理解，本申请实施例中提到的网络设备指示终端设备上报自干扰强度可以是上报直接表征该自干扰强度的信息，或者上报间接表征该自干扰强度的信息。
可选地，该自干扰强度为该终端设备在第一发射功率下的自干扰强度，该第一发射功率为该终端设备利用该第一上行频段向该网络设备发送信号的发射功率；终端设备接收该网络设备发送的第二指示信息，该第二指示信息用于指示该终端设备测量和/或上报在该第一发射功率下，该第一上行频段和该第一下行频段对该终端设备产生的自干扰强度。
可选地，在第一时间段内，利用该第一上行频率向该网络设备发送上行信号，以及在该第一下行频率上接收信号；将接收的信号的强度确定为该自干扰强度。
可选地，接收该网络设备发送的第三指示信息，该第三指示信息用于指示该终端设备在该第一时间段内，测量该第一上行频段和该第一下行频段对该终端设备产生的自干扰强度。
具体地，终端设备可以是可以在网络设备的指示下去测量自干扰强度。具体来说，终端设备可以向网络设备汇报终端设备具有测量自干扰强度的能力。
网络设备在获知终端设备的能力后，可以指示终端设备测量特定频段组合产生的自干扰强度，网络设备的指示将至少该频段组合，以及可选地包括频段组合中上行频段发射信号的发射功率，其中，如果包含多个上行频段(譬如互调干扰)，则需要指示各个上行频段的发射功率。
网络设备的指示还可以包括，终端设备进行自干扰强度测量的起止时间，因为终端设备在进行网络设备所指定的测量时，终端设备可能无法正常接收网络设备的下行信号，所以网络设备会为终端设备分配一定的时隙(譬如一些空闲子帧，或空闲符号)；终端设备将在网络设备分配的时隙内完成测量，在终端设备进行测量的过程中，终端设备将至少在测量的频段上不接收来自网络的下行信号。当终端设备测量完成后，终端设备将向网络设备汇报测量的结果，譬如通过高层信令向网络设备汇报。
因此，在该种实现方式中，终端设备可以按照网络设备的指示进行自干扰强度的测量，并且上报表征该自干扰强度的信息，可以避免终端设备预设过多的自干扰信息，以及避免预设的自干扰信息的不准确。
例如，即使是同一类型的终端设备，由于所用的射频器件很难保证完全一样的参数，设计过程中测量的自干扰信息，可能和一个终端设备实际使用时产生的自干扰还是有所区别。如果采用终端设备制造出来以后再测量的办法，只能适用于少量的终端设备，对于生产数量巨大的终端设备，不太现实。
再例如，当产生自干扰的频段组合较多时，所有可能的自干扰信息量会非常大。譬如互调干扰，产生互调干扰的两个上行信号的带宽分别会对受互调干扰影响的带宽产生影响，同时产生互调干扰的两个上行信号的功率，也会对干扰的强度产生影响，而且随着互调种类(阶数)的不同，上述结果还会不同。预先考虑上述所有组合，再加上产生干扰的各种频段组合，最后的自干扰信息量是非常巨大的。
应理解，本申请实施例中第一上行频段和第一下行频段可以分别是由不同的网络设备调度的，终端设备可以向其中的任一个或全部网络设备上报该自干扰强度。例如，第一上行频段是终端设备与第一网络设备进行通信的频段，第二上行频段是终端设备与第二网络设备进行通信的频段，该终端设备可以向第一网络设备和/或第二网络设备上报该自干扰强度以及上述其他的信息。
图3是根据本申请实施例的无线通信方法300的示意性流程图。该方法300可选地可以应用于图1所示的无线通信系统中。该方法可选地可以由网络设备执行。该方法300包括以下内容中的至少部分内容。
在310中，网络设备接收终端设备发送的第一消息，该第一消息用于表征该终端设备与网络设备进行通信的第一上行频段和第一下行频段对该终端设备产生的自干扰强度。
可选地，该第一上行频段包括多个频段；和/或，该第一下行频段包括多个频段。
可选地，该第一消息包括以下信息：该第一上行频段的信息；该第一下行频段的信息；和表征该自干扰强度的信息。
可选地，该第一消息还用于指示：该第一上行频段和该第一下行频段对该终端设备产生的自干扰的类型；和/或，第一发射功率，该第一发射功率为该终端设备利用该第一上行频段向该网络设备发送信号的发射功率。
可选地，在本申请实施例中，在接收终端设备发送的第一消息之前，网络设备向该终端设备发送指示信息，该指示信息用于指示：该终端设备测量 和/或上报该第一上行频段和该第一下行频段对该终端设备产生的自干扰强度。
该指示信息还用于指示以下中的至少一种：测量该自干扰强度时该终端设备利用该第一上行频率向该网络设备发送信号的发射功率；和/或，测量该自干扰强度的时间段。
可选地，在该指示信息指示的测量该自干扰强度的时间段内，网络设备不利用该第一下行频段向该终端设备发送下行信号。
可选地，该第一消息携带第一CQI，该第一CQI用于表征该第一下行频段和该第一上行频段对该终端设备产生的自干扰强度。
可选地，第一消息携带第一比特；在该第一比特取第一值时，表征该第一消息携带的CQI为该第一CQI；在该第一比特取值为第二值时，表征该第一消息的CQI为第二CQI，该第二CQI不用于表征该自干扰强度。
在320中，根据该自干扰强度，网络设备对该终端设备进行调度。
具体地，网络设备接收到终端设备汇报的该第一消息后，将知道终端设备在哪些频段上会产生自干扰，并且干扰强度有多大。网络设备可以对应的做出调度，例如，避免调度终端设备在有强自干扰的接收频段上接收下行信号；或者不调度终端设备在会产生自干扰的频段组合上同时收发信号。
应理解，该方法300中的各种实现方式可以参考方法200的描述，为了简洁，在此不再赘述。
因此，在本申请实施例中，终端设备确定终端设备与网络设备进行通信的第一上行频段和第一下行频段对该终端设备产生的自干扰强度，并向网络设备上报表征该自干扰强度的信息，从而网络设备可以根据表征该自干扰强度的信息，对终端设备进行调度，尽量避免在终端侧产生自干扰，提升通信性能。
