具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种通信方法的流程图，如图1所示，通信方法用于第二基站中，包括以下步骤。
在步骤101中，第二基站接收第一基站的符号配置信息，符号配置信息用于指示子帧内的上/下行符号配置情况。
在步骤102中，第二基站根据第一基站的符号配置信息和第二基站的符号配置信息，将第二基站的子帧中的指定符号配置为空白符号，指定符号为在通信时预测会发生干扰的符号。
在步骤103中，第二基站根据重新配置后的符号配置信息进行通信。
相关技术中，宏基站在通信时将整个上行子帧配置为空白子帧，避免干扰关联基站的下行通信。配置整个子帧为空白子帧的方式，不仅会浪费子帧资源，而且延迟了第二基站的通信进程，导致第二基站的通信效率很低。
本公开实施例中，将第二基站通信时预测会发生干扰的符号配置为空白符号，避免干扰第一基站在下行符号上进行通信。符号是子帧内更小的时间长度，相比相关技术，配置空白符号的方式不仅能节省子帧资源，而且不会过多延迟第二基站的通信进程，通信效率较高。
在一种可能实现方式中，方法包括：第二基站接收第一基站在第二基站建立后发送的符号配置信息；或，
第二基站接收第一基站在符号配置信息发生改变后发送的符号配置信息；或，
第二基站接收第一基站在业务需求发生改变后发送的符号配置信息。
在一种可能实现方式中，方法包括：当第一基站的子帧内和第二基站的子帧内均包括上行符号和下行符号时，第二基站确定第二基站的上行符号与第一基站的下行符号的重合位置，将重合位置的上行符号配置为空白符号；或，
当第一基站的子帧内包括上行符号和下行符号，第二基站的子帧内包括上行符号，但不包括下行符号时，第二基站将第二基站的子帧内的上行符号配置为空白符号；或，
当第二基站的子帧内包括上行符号和下行符号，第一基站的子帧内包括下行符号，但不包括上行符号时，第二基站将第二基站的子帧内的上行符号配置为空白符号。
在一种可能实现方式中，方法还包括：当第一基站的符号配置信息未包括第一基站的子帧内的全部符号配置信息时，第二基站确定目标符号的位置，将第二基站的子帧内与目标符号对应位置的上行符号配置为空白符号，目标符号为第一基站的子帧内，除符号配置信息所包括的符号以外的符号。
在一种可能实现方式中，方法还包括：当第二基站的符号配置信息包括未指定符号，且第一基站的符号配置信息未包括未指定符号时，第二基站将第一基站的下行符号对应位置的未指定符号配置为空白符号；或，
当第一基站的符号配置信息包括未指定符号，且第二基站的符号配置信息未包括未指定符号时，第二基站确定未指定符号的位置，在第二基站的子帧内与未指定符号的位置对应的上行符号配置空白符号；或，
当第二基站的符号配置信息和第一基站的符号配置信息均包括未指定符号时，第二基站将第一基站的下行符号对应位置的第二基站的未指定符号配置为空白符号，并在第二基站的子帧内，确定与第一基站的未指定符号对应位置的上行符号，将对应位置的上行符号配置为空白符号。
在一种可能实现方式中，方法包括：第二基站将第一符号配置信息发送至用户设备UE，使得UE在空白符号上不进行通信；或，
第二基站将第二符号配置信息发送至用户设备UE，第二符号配置信息携带预设功率，使得UE在空白符号上采用预设功率进行通信。
在一种可能实现方式中，第一基站为第二基站覆盖范围内的微基站；或第一基站为与第二基站覆盖范围重叠的宏基站；或第一基站为第二基站的邻基站。
上述所有可选技术方案，可以采用任意结合形成本公开的可选实施例，在此不再一一赘述。
图2A是根据一示例性实施例示出的一种子帧格式示意图。如图2A所示，一子帧内包括但不限于上行符号或下行符号。基站在上行符号上进行上行通信，在下行符号上进行下行通信。
另外，对于每个基站在下行通信转换成上行通信时，都有一段保护期，以避免该基站在上行通信时受到其关联基站下行通信的干扰。
图2B是根据一示例性实施例示出的一种通信方法的流程图，如图2B所示，通信方法用于基站中，包括以下步骤。
在步骤200中，第一基站向第二基站发送符号配置信息，符号配置信息用于指示子帧内的上/下行符号配置情况。
在本公开实施例中，第一基站是第二基站的关联基站。其中，当第二基站是宏基站时，第一基站可以是第二基站覆盖范围内的微基站；当第二基站是微 基站时，第一基站可以是与第二基站的覆盖范围重叠的宏基站；此外，第一基站还可以是第二基站的相邻基站，本公开实施例对此不做限定。
其中，符号配置信息包括但不限于子帧内符号的类别(例如上行符号、下行符号)、符号的位置和保护期的位置。
实际中，运营商根据第一基站可能受到的干扰影响程度或业务需求决策第二基站是否对该第一基站进行干扰避让，如需避让，则第一基站向第二基站发送符号配置信息，可能的发送情况至少有以下三种，本公开实施例对此不做限定：
例如，第一基站建立后，向第二基站发送符号配置信息。
例如，当第一基站的符号配置信息发生改变时，第二基站可能由不干扰第一基站转变成干扰第一基站，或者对第一基站继续造成干扰，因此，在本公开另一实施例中，第一基站的符号配置信息发生改变后，向第二基站发送符号配置信息。
例如，当第一基站的业务需求发生改变后，由运营商决策，第二基站可能要对该第一基站进行干扰避让，因此，本公开另一实施例中，第一基站在业务需求发生改变后，向第二基站发送符号配置信息。
在步骤201中，第二基站接收第一基站的符号配置信息。
需要说明的是，第一基站和第二基站地理位置较近，第二基站上行通信与第一基站下行通信在同一子帧内进行时，第二基站上行通信可能会干扰第一基站的下行通信，因此第二基站可以基于实际情况进行干扰避让。
实际中，第二基站可根据自身的通信情况或第一基站的通信需求决定是否避让，本公开对此不做限定。若需避让，则继续步骤202，若无需避让，则结束。例如，第二基站自身的通信效率较差，或，第一基站在某时段内通信质量需求低，第二基站无需避让时，可不进行步骤202。
在步骤202中，根据第一基站的符号配置信息和第二基站的符号配置信息，第二基站将第二基站的子帧中的指定符号配置为空白符号，指定符号为在通信时预测会发生干扰的符号。
需要说明的是，根据第一基站的符号配置信息和第二基站的符号配置信息，第二基站可以获知两个基站的子帧内符号的具体配置，比如，上/行符号的位置，从而确定，第一基站的下行符号与第二基站上行符号的重叠部分，重叠部分的上行符号即指定符号，在通信时预测会发生干扰。
本公开实施例中，当接收的第一基站的符号配置信息包括第一基站的子帧内的全部符号配置信息时，例如，图2A中的子帧包括子帧内的全部符号配置信息，在子帧的每个符号位置上均有对应的上行符号或下行符号或保护期。根据干扰情况，为防止第二基站在上行通信时干扰第一基站的下行通信，至少有以下三种配置空白符号的方式：
第一种方式、当第一基站的子帧内和第二基站的子帧内均包括上行符号和下行符号时，确定第二基站的上行符号与第一基站的下行符号的重合位置，将重合位置的上行符号配置为空白符号。
例如，图3是根据一示例性实施例示出的一种配置空白符号的示意图，如图3中(a)图所示，在配置空白符号前，在子帧内符号的位置3和位置7上，第二基站的上行符号与第一基站的下行符号有重叠，可能导致第二基站在位置3和位置7的上行符号上进行通信时，干扰第一基站的下行通信，因此，如图3中(b)图所示，将该重叠部分的上行符号配置为空白符号，避免干扰。
第二种方式、当第一基站的子帧内包括上行符号和下行符号，第二基站的子帧内包括上行符号，但不包括下行符号时，将第二基站的子帧内的上行符号配置为空白符号。
例如，图4是根据一示例性实施例示出的一种配置空白符号的示意图，如图4中(a)图所示，在配置空白符号前，第二基站在子帧内的上行符号进行通信时，会干扰第一基站在子帧内的对应下行符号上进行通信。因此，如图4中(b)图所示，在第二基站的子帧内的全部符号均配置为空白符号，以避免干扰。
第三种方式、当第二基站的子帧内包括上行符号和下行符号，第一基站的子帧内包括下行符号，但不包括上行符号时，将第二基站的子帧内的上行符号配置为空白符号。
例如，图5是根据一示例性实施例示出的一种配置空白符号的示意图，如图5中(a)图所示，在配置空白符号前，第二基站在每个上行符号上进行通信时，均会干扰第一基站在对应的下行符号上进行通信，因此，如图5中(b)图所示，将第二基站子帧内的全部上行符号配置为空白符号，以避免干扰。
实际中，接收的第一基站的符号配置信息可能未包括第一基站的子帧内的全部符号配置信息，由于符号配置信息未知，目标符号有可能是上行符号，此时，若第二基站的子帧内与目标符号对应位置的上行符号是上行符号，则会造 成干扰。其中，目标符号为第一基站的子帧内，除符号配置信息所包括的符号以外的符号。
例如，图6是根据一示例性实施例示出的一种配置空白符号的示意图，如图6中(a)图所示，第一基站的子帧的符号位置7上有目标符号，为避免可能干扰到第一基站在目标符号上通信，如图6中(b)图所示，确定目标符号的位置，将第二基站的子帧内与目标符号对应位置的上行符号配置为空白符号。
考虑到子帧内有未指定符号的情况时，由于未指定符号在实际通信过程中，可能是上行符号或下行符号，所以第二基站不能在通信前确定未指定符号的实际配置情况。因此，当第二基站的未指定符号为上行符号时或第一基站的未指定符号为下行符号时，均可能使第二基站干扰第一基站的通信，因此，本公开实施例中，至少还有以下三种配置空白符号的方式，以避免可能发生的干扰：
第四种方式、当第二基站的符号配置信息包括未指定符号，且第一基站的符号配置信息未包括未指定符号时，将第一基站的下行符号对应位置的未指定符号配置为空白符号。
例如，图7是根据一示例性实施例示出的一种配置空白符号的示意图，如图7中(a)图所示，第二基站在子帧的符号位置1和符号位置3上有未指定符号，为避免第二基站在未指定符号上进行通信时是上行通信，对第一基站对应位置的下行通信造成干扰，如图7中(b)图所示，将未指定符号配置为空白符号。
第五种方式、当第一基站的符号配置信息包括未指定符号，且第二基站的符号配置信息未包括未指定符号时，确定未指定符号的位置，在第二基站的子帧内与未指定符号的位置对应的上行符号配置空白符号。
例如，图8是根据一示例性实施例示出的一种配置空白符号的示意图，如图8中(a)图所示，第一基站在子帧的符号位置7有未指定符号，若第一基站在未指定符号进行下行通信，如图8中(b)图所示，为避免第二基站在对应的上行符号进行通信时的干扰，将第一基站位置7的上行符号配置为空白符号。
第六种方式、当第二基站的符号配置信息和第一基站的符号配置信息均包括未指定符号时，将第一基站的下行符号对应位置的第二基站的未指定符号配 置为空白符号，并在第二基站的子帧内，确定与第一基站的未指定符号对应位置的上行符号，将对应位置的上行符号配置为空白符号。
例如，图9是根据一示例性实施例示出的一种配置空白符号的示意图，如图9中(a)图所示，第二基站子帧的符号位置1和位置2有未指定符号，为避免干扰第一基站在位置1和位置2上进行下行通信，在第二基站的位置1和位置2上配置空白符号，此外，第一基站子帧的符号位置7上有未指定符号，为避免第二基站在位置7的上行符号上进行通信时造成干扰，将该位置的上行符号配置为空白符号，配置结果如图9中(b)图所示。
在步骤203中，在子帧内配置空白符号后，第二基站将重新配置后的符号配置信息发送至用户设备UE，使UE按照重新配置后的符号配置信息进行通信。
本公开实施例中，重新配置后的符号配置信息可以是第一符号配置信息。当第二基站发送第一符号配置信息到UE时，使UE在空白符号上不进行上行通信，在子帧内除配置的空白符号的以外符号上进行上行通信，避免干扰第一基站的下行通信。
对第一基站进行干扰避让的同时，为保证第二基站的通信效率，在本公开另一种实施例中，重新配置后的符号配置信息可以是第二符号配置信息，第二符号配置信息携带第二基站对UE限定的预设功率，例如，预设功率可以是原功率的50％，本公开对此不做限定，当第二基站发送第二符号配置信息到UE时，使UE在空白符号上采用预设功率进行通信，在子帧内除配置的空白符号以外的符号上进行正常通信。
相关技术中，宏基站在通信时将整个上行子帧配置为空白子帧，避免干扰关联基站的下行通信。配置整个子帧为空白子帧的方式，不仅会浪费子帧资源，而且延迟了本基站的通信进程，导致本基站的通信效率很低。
本公开实施例中，将第二基站通信时预测会发生干扰的符号配置为空白符号，避免干扰第一基站在下行符号上进行通信。符号是子帧内更小的时间长度，相比相关技术，配置空白符号的方式不仅能节省子帧资源，而且不会过多延迟第二基站的通信进程，通信效率较高。
另外，本公开实施例中，第二基站对第一基站进行干扰避让的同时，第二基站支持UE采用预设功率进行通信，保证了第二基站的通信效率。
图10是根据一示例性实施例示出的一种通信装置框图。应用于第二基站，参照图10，该装置包括接收模块1001，配置模块1003和通信模块1003。
该接收模块1001被配置为接收第一基站的符号配置信息，符号配置信息用于指示子帧内的上/下行符号配置情况。
该配置模块1002被配置为根据第一基站的符号配置信息和第二基站的符号配置信息，将第二基站的子帧中的指定符号配置为空白符号，指定符号为在通信时预测会发生干扰的符号。
该通信模块1003被配置为根据重新配置后的符号配置信息进行通信。
在一种可能实现方式中，该接收模块1001被配置为接收第一基站在第二基站建立后发送的符号配置信息；或，
接收第一基站在符号配置信息发生改变后发送的符号配置信息；或，
接收第一基站在业务需求发生改变后发送的符号配置信息。
在一种可能实现方式中，该配置模块1002被配置为当第一基站的子帧内和第二基站的子帧内均包括上行符号和下行符号时，确定第二基站的上行符号与第一基站的下行符号的重合位置，将重合位置的上行符号配置为空白符号；或，
当第一基站的子帧内包括上行符号和下行符号，第二基站的子帧内包括上行符号，但不包括下行符号时，将第二基站的子帧内的上行符号配置为空白符号；或，
当第二基站的子帧内包括上行符号和下行符号，第一基站的子帧内包括下行符号，但不包括上行符号时，将第二基站的子帧内的上行符号配置为空白符号。
在一种可能实现方式中，该配置模块1002还被配置为当第一基站的符号配置信息未包括第一基站的子帧内的全部行符号配置信息时，确定目标符号的位置，将第二基站的子帧内与目标符号对应位置的上行符号配置为空白符号，目标符号为第一基站的子帧内，除符号配置信息所包括的符号以外的符号。
在一种可能实现方式中，该配置模块1002还被配置为当第二基站的符号配置信息包括未指定符号，且第一基站的符号配置信息未包括未指定符号时，将第一基站的下行符号对应位置的未指定符号配置为空白符号；或，
当第一基站的符号配置信息包括未指定符号，且第二基站的符号配置信息未包括未指定符号时，确定未指定符号的位置，在第二基站的子帧内与未指定 符号的位置对应的上行符号配置空白符号；或，
当第二基站的符号配置信息和第一基站的符号配置信息均包括未指定符号时，将第一基站的下行符号对应位置的第二基站的未指定符号配置为空白符号，并在第二基站的子帧内，确定与第一基站的未指定符号对应位置的上行符号，将对应位置的上行符号配置为空白符号。
在一种可能实现方式中，该通信模块1003被配置为将第一符号配置信息发送至用户设备UE，使得UE在空白符号上不进行通信；或，
将第二符号配置信息发送至用户设备UE，第二符号配置信息携带预设功率，使得UE在空白符号上采用预设功率进行通信。
在一种可能实现方式中，第一基站为第二基站覆盖范围内的微基站；或第一基站为与第二基站覆盖范围重叠的宏基站；或第一基站为第二基站的邻基站。
相关技术中，宏基站在通信时将整个上行子帧配置为空白子帧，避免干扰第一基站的下行通信。配置整个子帧为空白子帧的方式，不仅会浪费子帧资源，而且延迟了本基站的通信进程，导致本基站的通信效率很低。
本公开实施例中，将第二基站通信时预测会发生干扰的符号配置为空白符号，避免干扰第一基站在下行符号上进行通信。符号是子帧内更小的时间长度，相比相关技术，配置空白符号的方式不仅能节省子帧资源，而且不会过多延迟第二基站的通信进程，通信效率较高。
另外，本公开实施例中，第二基站对第一基站进行干扰避让的同时，第二基站支持UE采用预设功率进行通信，保证了第二基站的通信效率。
关于上述实施例中的装置，其中各个模块执行操作的具体方式已经在有关该方法的实施例中进行了详细描述，此处将不做详细阐述说明。
本公开实施例进一步给出实现上述方法实施例中各步骤及方法的装置实施例。本公开实施例可应用于各种通信系统中的基站。
请参考图11，其为本公开实施例所提供的一种基站的结构示意图。如图所示，该基站包括发射机1101、接收机1102、存储器1103以及分别与发射机、接收机和存储器连接的处理器1104。当然，基站还可以包括天线、基带处理部件、中射频处理部件、输入输出装置等通用部件，本公开实施例在此不再任何限制。
