本公开实施例提供了一种信息传输方法，应用于终端，如图2所示，该方法包括步骤21至23。
步骤21：在第一时频资源上发送第一信号。
其中，第一时频资源可以是终端建议的、网络设备配置的或预定义(如协议约定)的等。第一时频资源可以是周期性资源也可以是非周期性资源。例如，基于一个资源块(Resource Block，RB)，其中，一个RB包含12个子载波，选取其中的第4、8号子载波置1，其余子载波置0作为第一信号。第 一信号的时域长度为5个2048点的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号。
步骤22：在第二时频资源上对第一信号产生的自干扰进行自干扰估计，得到自干扰参数。
第二时频资源为：第一时频资源上发送的第一信号产生的自干扰信号所在的时频资源，即第二时频资源为第一信号的自干扰影响的时频资源。第二时频资源与第一时频资源在频域上满足特定关系，例如第二时频资源的频域范围是第一时频资源的频域范围的整数倍、分数倍或不同频域范围的差值相关的范围等。例如，1.8GHz上行信号和3.5GHz上行信号产生的二阶交调干扰会影响到终端在1.8GHz附近的下行接收信号；1.8GHz上行信号的二次谐波会影响到3.5GHz附近的下行接收信号。进一步地，第二时频资源与第一时频资源在时域上至少部分重叠，在一种特殊实施例中，第二时频资源的时域范围包括第一时频资源的时域范围，或者两类时域范围重叠或一致，这样可对第一信号的完整自干扰信号进行估计。
其中，自干扰参数包括：与谐波干扰相关的第一参数、与谐波混合干扰相关的第二参数以及与交调干扰相关的第三参数中的至少一项。对于第一参数，第二参数和第三参数，具体的参数项包括：自干扰的信道的信道值，自干扰模型(用于重建自干扰)的相关参数项，或者其他参数项等。终端根据这些自干扰参数可计算出上行信号的自干扰信号。其中，值得指出的是，步骤21和步骤22为自干扰估计和训练过程，该过程可以是周期性的，或基于网络设备指示的。假设该过程为周期性的，那么在一个周期内的自干扰参数不变。假设该过程是基于网络设备指示的，那么在网络设备指示终端重新进行自干扰估计之前，终端将保持自干扰参数不变。这样终端在确定发生自干扰的情况下，无需每次都进行自干扰估计和训练，可降低终端的处理工作量，节省电能。
步骤23：在发生自干扰的情况下，根据自干扰参数，对接收到的第二信号进行自干扰消除。
其中，第二信号包括网络设备发送的下行信号(或称为有用信号)，以及终端发送的上行信号产生的自干扰信号，其中，该自干扰信号会影响下行信 号。其中，终端根据步骤22估计训练出来的自干扰参数和上行信号重建出上行信号对应的自干扰信号，并将该自干扰信号从第二信号中消除，以提高下行信号的可靠性，提高下行传输性能。
本公开实施例中，步骤21之前，还包括：从网络设备接收第一信号的配置信息，该配置信息用于指示终端发送第一信号。本公开实施例的配置信息可携带于第一信令中，终端接收网络设备发送的第一信令，该第一信令指示终端在第一时频资源上发送第一信号。其中，该第一信令可以是网络设备确定并下发终端的，也可以是网络设备接收到终端请求后下发的。以终端请求为例，终端在从网络设备接收第一信号的配置信息的步骤之前还包括：向网络设备发送请求信息(或称为请求授权)；其中，请求信息用于请求网络设备发送第一信号的配置信息，即该请求信息用于指示终端有自干扰估计的需求，需要发送第一信号。请求信息中还可以包括自干扰的类型，如谐波干扰、谐波混合干扰、交调干扰等。其中，发送第一信号的第一时频资源可以是终端建议的，为节省信令，终端可在向网络设备发送的请求信息中携带建议的第一时频资源。
进一步地，对于特定频段下的双连接DC、载波聚合(Carrier Aggregation，CA)、NR SUL传输等场景，由于终端发射链路的非理想特性，终端的一条或多条上行链路发射时可能会产生谐波干扰、谐波混合(harmonics mixing)干扰或交调干扰等自干扰问题，终端需要发送第一信号进行自干扰估计。网络设备向终端发送第一信号的配置信息，该配置信息可以是与终端保持连接的至少一个网络设备中的一个下发给终端的。
其中，本公开实施例中，第一信号的配置信息包括但不限于以下信息中的至少一项：
指示第一时频资源的第一指示信息；当配置信息携带于网络设备下发的第一信令中时，该第一信令指示的内容包括发送第一信号的时频资源；例如，该第一信令指示的内容包括发送第一信号的时域资源和频域资源的至少一项。
指示第一信号的发射功率的第二指示信息；当配置信息携带于网络设备下发的第一信令中时，该第一信令指示的内容包括终端发送第一信号的发射功率。其中，一个第一信令可指示一种或多种发射功率，当一个第一信令指 示多种发射功率时，终端可遍历不同的发射功率，例如按照步长2dB进行遍历。具体地，当自干扰为交调干扰时，终端需要遍历至少两个上行频点的不同发射功率的各种组合。
指示第一信号的发射天线的第三指示信息；当配置信息携带于网络设备下发的第一信令中时，该第一信令指示的内容包括终端发送第一信号的发射天线，以NR 2Tx为例，该第一信令可指示发送第一信号的发射天线为这2Tx中的哪个。
指示第一信号对应的定时提前(Timing Advance，TA)的第四指示信息；当配置信息携带于网络设备下发的第一信令中时，该第一信令指示的内容包括终端发送第一信号的TA，其中，一个第一信令指示一个或多个TA，当第一信令指示多个TA时，终端可遍历不同的TA。具体地，当自干扰为交调干扰时，终端需要遍历至少两个上行频点的不同TA的各种组合。值得指出的是，不同场景的自干扰影响和估计可能不同。
以及，指示第一信号的发送序列的序列参数的第五指示信息，其中，序列参数包括但不限于序列格式、序列种类等参数。当配置信息携带于网络设备下发的第一信令中时，该第一信令指示的内容包括终端发送的第一信号为何种序列，以及终端生成第一信号序列时所采用的序列参数。其中，所述序列格式、序列种类、序列参数的集合可以是预定义(如协议约定)的或者网络设备侧配置的，具体的序列格式、序列种类、序列参数是网络设备侧指示的。
进一步地，为了保证终端更好的进行自干扰估计，在步骤22之前还包括：向网络设备发送禁止在第三时域资源上进行下行传输的禁止请求，其中，第三时域资源与第二时频资源在时域上至少部分重叠。也就是说，终端向保持连接的网络设备中的一个发送禁止请求，以请求网络设备不在第三时频资源上进行下行传输，这样在第三时频资源上若接收到信号，则全部为自干扰信号。具体地，对于E-UTRA-NR Dual Connectivity(EN-DC)场景的谐波干扰，终端向第二基站请求，对于EN-DC场景的交调干扰，终端向第一基站请求。其中，第三时频资源可以是终端建议的、预定义(如协议约定)的、或者根据第一时频资源和预设规则确定出的。具体地，第三时频资源是与第二时频资源关联的时频资源，例如二者的时域资源一致，或者，第三时频资源为第二 时频资源加上时域或者频域保护带，即第三时频资源包括第二时频资源的全部时频资源，这样在第二时频资源上，终端只会接收到自干扰信号，没有其他下行信号的影响，终端可更好的进行自干扰估计。
其中，本公开实施例适用于DC、CA、SUL等场景。其中，第一时频资源对应的频点为第一系统频点，第二时频资源对应的频点为第一系统频点的整数倍或分数倍的相关频点。以EN-DC为例，第一时频资源对应的频点为1.8GHz，第二时频资源对应的频点为3.6GHz，第二时频资源上产生的二次谐波干扰信号可影响3.6GHz的下行信号。或者，第一时频资源对应的频点为3.5GHz，第二时频资源对应的频点为1.75GHz，第二时频资源上产生的谐波混合干扰信号可影响1.75GHz的下行信号。
此外，第一时频资源对应的频点为第一系统频点和第二系统频点，第二时频资源对应的频点为第一系统频点和第二系统频点之间的差值的相关频点。以EN-DC为例，第一时频资源对应的频点为1.8GHz和3.5GHz，第二时频资源对应的频点为1.7GHz，在第二时频资源上产生的交调干扰信号可影响1.7GHz的下行信号。
本公开实施例中，步骤21的步骤可通过以下方式实现：若第一时频资源对应的频点为第一系统频点，在第一系统频点的至少两个子载波上，发送第一信号。即第一信号采用双频信号。或者，若第一时频资源对应的频点为第一系统频点和第二系统频点，在第一系统频点的至少两个子载波以及第二系统频点的至少两个子载波上，发送第一信号。也就是说，第一信号在某个系统频点对应的两个子载波上发送(双频信号)，或者在多个子载波上发送。
进一步地，第一时频资源包括与终端保持连接的至少一个系统的至少部分空闲时域资源，空闲时域资源包括：空闲子帧、空闲时隙、空闲时域符号、用于保护周期的子帧、用于保护周期的时隙和用于保护周期的时域符号中的至少一项。例如第一时频资源位于或包括系统的空闲时隙，如LTE系统的保护间隔(Guard Period，GP)，或NR系统的灵活符号(flexible symbol)等。
本公开实施例中，在发生自干扰的情况下，根据自干扰参数，对接收到的第二信号进行自干扰消除。其中，第二信号包括：网络设备发送的下行信号和终端上行信号产生的自干扰信号等，该自干扰信号会影响下行信号。
在自干扰消除的步骤之前还包括：根据同步指示信息，在第四时频资源上发送同步信号；在第五时频资源上接收同步信号；根据同步信号进行同步。其中，同步信号采用的序列可以是时域Chu序列或者其他类型的序列；
Chu序列产生公式：
Figure PCTCN2019122637-appb-000002
其中，0≤n≤N ZC，N ZC＝839，u为常数。同步信号的时域长度可以是1个OFDM符号。其中，第五时频资源与第四时频资源在时域上至少部分重叠。其中，同步指示信息可以是网络设备发送给终端的，也就是说，在根据同步指示信息，在第四时频资源上发送同步信号的步骤之前还包括：从网络设备侧接收同步指示信息。其中，同步指示信息可携带于第二信令中。也就是说，终端接收网络设备发送的第二信令，该第二信令指示终端在第四时频资源上发送同步信号，并在第五时频资源上接收同步信号进行同步。其中，第五时频资源是第四时频资源上发送的同步信号的自干扰信号所影响的时频资源。
本公开实施例中所提及的用于自干扰估计的第一信号可以是探测参考信号(Sounding Reference Signal，SRS)、解调参考信号(De-Modulation Reference Signal，DMRS)、随机接入信道(Random Access Channel，RACH)前导码、物理上行控制信道(Physical Uplink Control Channel，PUCCH)以及专用参考信号中的至少一项。其中，专用参考信号可以为用于自干扰估计的专用信号。
其中，本公开实施例中，时频资源(如第一时频资源、第二时频资源、第三时频资源等)包括时域资源、频域资源和时频域资源。

本公开实施例可适用于特定频段下的DC、CA、SUL传输等场景，以DC为例，网络设备可以是为DC系统中的第一基站和第二基站中的一个，相应地，其他网络设备为DC系统中第一基站和第二基站中的另一个。
方式三、从其他网络设备侧接收第一信号的参考配置信息，根据参考配置信息，确定向终端发送的配置信息。
其中，其他网络设备服务于终端且不同于该网络设备。该方式为方式一和二的结合。假设网络设备可以是为DC系统中的第一基站和第二基站中的一个，相应地，其他网络设备为DC系统中第一基站和第二基站中的另一个。例如网络设备为第一基站，其他网络设备为第二基站，第一基站从第二基站 侧接收第一信号的参考配置信息，第一基站根据接收到的参考配置信息以及资源调度等情况，为第一信号确定配置信息。
采用该方式确定配置信息后还包括：将配置信息反馈给其他网络设备，即将最后确定的配置信息反馈给其他网络设备。
另外，步骤51可以是网络设备直接将配置信息发送给终端，也可以是将配置信息发送给其他网络设备，由其他网络设备转发给终端。具体地，步骤51包括：向其他网络设备发送配置信息，以使其他网络设备将配置信息转发给终端，其中，其他网络设备服务于终端且不同于网络设备。
本公开实施例中的第一时频资源可以对应于网络设备，即第一时频资源为网络设备的时频资源。另外，第一时频资源还可以对应于其他网络设备，即第一时频资源为其他网络设备的时频资源。以第一网络设备为第一基站，第二网络设备为第二基站为例，第一基站接收第二基站发送的自干扰估计的配置信息，该配置信息指示终端在第一时频资源发送第一信号，其中，第一时频资源为第一基站的时频资源，即终端在第一基站的时频资源上发送第一信号。另外，第一时频资源还可以是第二基站的时频资源，即终端在第二基站的时频资源上发送第一信号。
本公开实施例中配置信息包括但不限于以下信息中的至少一项：
指示第一时频资源的第一指示信息；
指示第一信号的发射功率的第二指示信息；
指示第一信号的发射天线的第三指示信息；
指示第一信号对应的定时提前TA的第四指示信息；以及
指示第一信号的发送序列的序列参数的第五指示信息。
其中，该配置信息的说明可参见终端侧实施例，故在此不再赘述。
第一信号用于终端的自干扰估计，为了更好的提高自干扰估计性能，步骤51之后还包括：接收禁止在第三时频资源上进行下行传输的禁止请求，其中，第三时频资源与第二时频资源在时域上至少部分重叠，第二时频资源与第一时频资源在时域上至少部分重叠。也就是说，终端向保持连接的网络设备中的一个发送禁止请求，以请求网络设备不在第三时频资源上进行下行传输，这样在第三时频资源上若接收到信号，则全部为自干扰信号。其中，第三 时频资源可以是终端建议的、预定义(如协议约定)的、或者根据第一时频资源和预设规则确定出的。具体地，第三时频资源是与第二时频资源关联的时频资源，例如二者的时域资源一致，或者，第三时频资源为第二时频资源加上保护带，即第三时频资源包括第二时频资源的全部时域资源，这样在第二时频资源上，终端只会接收到自干扰信号，没有其他下行信号的影响，终端可更好的进行自干扰估计。
本公开实施例的信息传输方法中，网络设备向终端发送第一信号的配置信息，以指示终端发送用于自干扰估计的第一信号，终端可根据自身发送的第一信号进行自干扰消除的相关参数的估计和训练，进一步对接收到的下行信号进行自干扰消除，减少自干扰影响，提升下行链路的性能。
