具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
如图4所示，本公开的实施例提供一种特殊子帧的配置方法，包括：
步骤41，在特殊子帧配置采用配置10时，向终端发送DwPTS的配置的指示信息，所述DwPTS的配置的指示信息用于指示DwPTS是否有CRS(Common Reference Signal，公共参考信号)传输，和/或指示DwPTS是否有PDSCH传输；这里的特殊子帧配置包括：DwPTS、GP以及UpPTS所占用的资源配比为6:2:6，具体可以是，如图2所示，DwPTS占用6个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号资源，GP占用2个OFDM符号资源，UpPTS占用6个OFDM符号资源；进一步地， 如图5所示，特殊子帧配比为6:2:6时，一个物理资源块(Physical Resource Block，PRB)中的传输资源包括物理下行控制信道(Physical Downlink Control Channel，PDCCH)、主同步序列(Primary Synchronization Signal，PSS)、CRS、PDSCH、GP和UpPTS。
步骤42，向终端发送所述指示信息，可以通过高层信令向终端发送所述指示信息，为了同时允许无线资源控制(Radio Resource Control，RRC)空闲态的终端和RRC连接态的终端接收这一高层信令，这里的高层信令可以是广播信息发送或终端专属无线资源管理RRC信令。具体地，可以是TDD配置信息元素(TDD-Config information element)中增加信令指示DwPTS中的数据区域中是否传输CRS。
TDD-Config information element的具体格式如下：

Figure PCTCN2018104251-appb-000002
也可以是系统信息块类型1消息(SystemInformationBlockType1message)中增加信令指示DwPTS中的数据区域中是否传输CRS。
Figure PCTCN2018104251-appb-000003
也可以是无线资源配置公共信息元素(RadioResourceConfigCommon information element)中增加信令指示DwPTS中的数据区域中是否传输CRS。

Figure PCTCN2018104251-appb-000005
Figure PCTCN2018104251-appb-000006
在该实施例的一种具体实现中，所述指示信息可以用于指示在DwPTS是否有PDSCH传输；也可以通过基站调度的方式选择是否调度PDSCH资源。
具体的，(1)对于特殊子帧配置6:2:6，为了减少下行传输，基站选择不调度6个下行符号中的PDSCH用于传输用户的业务数据资源；对终端侧而言，假设在DwPTS中的第4、5、6个符号上不传输PDSCH资源，终端在特殊子帧不解调PDSCH；如图6所示。
由于在第五个符号上的CRS总是存在，仍然可以被传输，会对受扰基站造成干扰。CRS是公共参考信号，作用是：(1)下行信道质量测量，如参考信号接收功率(Reference Signal Receiving Power，RSRP)；(2)下行信道估计，用于用户(User Experience，UE)端的相关检测和解调。
在该实施例的另一种具体实现中，所述指示信息若指示在DwP TS的第5个符号上没有CRS的传输，和/或所述指示信息若指示DwPTS中仅第1个符号上有CRS传输，终端在特殊子帧仅基于第1个符号的CRS进行测量和/或用于解调的信道估计；
所述基于CRS进行的测量和/或用于解调的信道估计，包括无线资源管理 (Radio Resource Management，RRM)测量和/或信道状态信息(Channel State Information，CSI)测量和/或针对物理下行控制信道PDCCH进行解调的信道估计。
在长期演进(Long Term Evolution，LTE)中，本公开的该实施例中，新增高层信令指示，当高层信令指示特殊子帧配置6:2:6的DwPTS的第5个符号上没有CRS的传输，和/或所述指示信息若指示DwPTS中仅第1个符号上有CRS传输，终端在特殊子帧仅基于第1个符号的CRS进行测量和/或用于解调的信道估计，如图7所示。
本公开的上述实施例，通过在特殊子帧配置采用配置10时，向终端发送DwPTS的配置的指示信息，所述DwPTS的配置的指示信息用于指示DwPTS是否有CRS传输，和/或指示DwPTS是否有PDSCH传输；通过高层信令向终端发送所述指示信息；对特殊子帧配置的终端测量行为进行限制，明确UE不需要在特殊子帧的数据区域进行CRS测量，从而减少远端基站干扰。
本公开的实施例还提供一种基站，包括：
处理器，用于在特殊子帧配置采用配置10时，向终端发送DwPTS的配置的指示信息，所述DwPTS的配置的指示信息用于指示DwPTS是否有CRS传输，和/或指示DwPTS是否有PDSCH传输
收发机，用于向终端发送所述指示信息，具体可以通过高层信令向终端发送所述指示信息。
其中，所述指示信息用于指示DwPTS的第5个符号上是否有CRS传输；和/或
所述指示信息用于指示DwPTS中仅第1个符号上有CRS传输。
所述高层信令为广播信息发送或终端专属无线资源管理RRC信令。
需要说明的是，该基站的实施例是与上述方法对应的设备，上述方法实施例中的所有实现方式均适用于该基站的实施例中，也能达到相同的技术效果。

步骤82，根据所述指示信息，对DwPTS的信号进行检测。
本公开的该实施例的一具体实现中，步骤81中，所述指示信息用于指示DwPTS的第5个符号上是否有CRS传输时，步骤82包括：根据所述指示信息，若指示在DwPTS的第5个符号上没有CRS的传输，终端在特殊子帧仅基于第1个符号的CRS进行测量和/或用于解调的信道估计。
本公开的该实施例的一具体实现中，步骤81中，所述指示信息用于指示DwPTS中仅第1个符号上有CRS传输时，步骤82包括：根据所述指示信息，终端在特殊子帧仅基于第1个符号的CRS进行测量和/或用于解调的信道估计。
本公开的该实施例的一具体实现中，步骤81中，所述指示信息用于指示DwPTS是否有PDSCH传输时，步骤82包括：根据所述指示信息，若指示DwPTS无PDSCH传输，终端在特殊子帧不解调PDSCH。
本公开的该实施例中，所述高层信令为广播信息发送或终端专属无线资源管理RRC信令；通过接收基站通过高层信号发送的指示信息，接收基站通过高层信令发送的指示信息，所述指示信息为在特殊子帧配置采用配置10时，向终端发送DwPTS的配置的指示信息，所述DwPTS的配置的指示信息用于指示DwPTS是否有CRS传输，和/或指示DwPTS是否有PDSCH传输；根据所述指示信息，对DwPTS的信号进行检测，对特殊子帧配置的终端测量行为进行限制，明确UE不需要在特殊子帧的数据区域进行CRS测量，从而减少远端基站干扰。
本公开的实施例还提供一种终端，包括：
收发机，用于接收基站发送的指示信息，具体可以接收基站通过高层信令发送的指示信息，所述指示信息为在特殊子帧配置采用配置10时，向终端发送DwPTS的配置的指示信息，所述DwPTS的配置的指示信息用于指示DwPTS是否有CRS传输，和/或指示DwPTS是否有PDSCH传输；
并根据所述指示信息，对DwPTS的信号进行检测。
其中，所述指示信息用于指示DwPTS的第5个符号上是否有CRS传输时，所述收发机根据所述指示信息，若指示在DwPTS的第5个符号上没有 CRS的传输，终端在特殊子帧仅基于第1个符号的CRS进行测量和/或用于解调的信道估计。
其中，所述指示信息用于指示DwPTS中仅第1个符号上有CRS传输时，所述收发机根据所述指示信息，终端在特殊子帧仅基于第1个符号的CRS进行测量和/或用于解调的信道估计。

本公开的实施例还提供一种特殊子帧的配置方法，包括：
对第二基站造成远端干扰的第一基站按照特殊子帧的第一配置，和终端传输信号；
第二基站按照特殊子帧的第二配置，和终端传输信号；
其中，第一配置为：特殊子帧的DwPTS、GP以及UpPTS所占用的资源配比为3:5:6；
所述第二配置为：特殊子帧的DwPTS、GP以及UpPTS所占用的资源配比为9:3:2。
具体的，如图9所示，若远端基站(施扰基站)和近端基站，均采用特殊子帧中DwPTS、GP以及UpPTS所占用的资源配比为9:3:2，远端基站的信号在传播时延延期一段时间后，近端基站的UpPTS与远端基站的DwPTS同时进行发送信号，则施扰基站的下行会对受扰基站的上行造成强干扰；
如图10所示，远端基站(施扰基站)采用特殊子帧中DwPTS、GP以及UpPTS所占用的资源配比为3:5:6以后，施扰基站(远端基站)的特殊子帧的GP对应于受扰基站(近端基站)的特殊子帧上行传输UpPTS，因此施扰基站的下行传输不会对受扰基站的上行传输造成干扰。
本公开的实施例还提供一种基站，该基站可以采用上述远端基站的配置， 包括：处理器，用于按照特殊子帧的第一配置对特殊子帧进行配置；其中，第一配置为：特殊子帧的DwPTS、GP以及UpPTS所占用的资源配比为3:5:6；
