Description

一种降低终端设备干扰的方法及基站
本申请中要求在2017年08月07日提交中国专利局、申请号为201710667003.4、申请名称为“一种降低终端设备干扰的方法及基站”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信领域，尤其涉及一种降低终端设备干扰的方法及基站。
背景技术
在无线通信网络中，终端设备在其服务基站的覆盖范围内进行通信时会受到其他基站的信号干扰，这种终端设备通信时受到其他基站的信号干扰的现象在飞行终端设备上更加明显。
飞行终端设备通过无线通信网络在空中通信时，飞行终端设备的飞行高度通常远远高于基站天线高度，飞行终端设备的视线传播无障碍，在空中能够看见更多的基站，因此在满足空中的覆盖信号强度的情况下，飞行终端设备会受到来自其他基站的较强的信号干扰。飞行终端设备通过无线通信网络在空中通信时，随着飞行终端设备的飞行高度升高，信号强度越来越强，而干扰加噪声比(signal to interference plus noise ratio，SINR)干扰越来越强，并且飞行终端设备在空中通信时由于受到来自其他基站的较强的信号干扰而容易发生卡顿现象。
目前终端设备的抗干扰协调技术主要是小区间干扰协调(inter-cell interference coordination，ICIC)技术，但由于飞行终端设备在空中飞行时能够搜索到更多的基站，因此飞行终端设备的干扰小区个数相对于地面的干扰小区个数变多，从而导致资源协调受限，因此使用ICIC技术无法完成资源协调，从而干扰也就无法避免。
综上所述，在干扰小区数量较多的情况下，采ICIC技术，抗干扰效果不佳。
发明内容
本申请实施例提供一种降低终端设备干扰的方法及基站，用以实现降低无线通信网络中终端设备在其服务基站的覆盖范围内进行通信时受到的来自其他基站的信号干扰，尤其适用于飞行终端设备。
第一方面，本申请实施例提供一种降低终端设备干扰的方法，包括：
第一基站确定第一信息，所述第一信息用于指示终端设备的传输资源的资源位置；
所述第一基站确定第二信息，所述第二信息用于指示第二基站将所述资源位置对应的子帧配置为指定类型的子帧，或者所述第二信息用于指示所述传输资源的优先级级别，其中，所述第一基站为所述终端设备的服务基站；
所述第一基站向所述第二基站发送所述第一信息和所述第二信息。
其中，终端设备的传输资源是第一基站分配给该终端设备的专用传输资源，终端设备的传输资源可以是时域资源，也可以是频域资源。例如，传输资源为时域资源时，该时域资源的资源位置可以是指该时域资源对应的子帧的子帧号；又例如，传输资源为频域资源时，该频域资源的资源位置可以是指该频域资源对应的物理资源块PRB的位置，该PRB 可以是子帧中的部分PRB。第二基站可以为一个或者多个，第二基站为对终端设备干扰较大的基站。
通过上述方法，使得第二基站能够从第一基站接收第一信息和第二信息，第二基站接收到第一信息和第二信息后会根据第一信息和第二信息的指示，将所述资源位置对应的子帧配置为所述指定类型的子帧，或者基于第一信息和第二信息进行动态ICIC，进而减少第二基站使用终端设备的传输资源，从而使得终端设备在第一基站的覆盖范围内使用传输资源进行通信时受到第二基站的信号干扰大幅度降低。
在一种可能的实现方式中，所述第二信息用于指示第二基站将所述资源位置对应的子帧配置为指定类型的子帧时，包括如下两种情况：
一种情况为：所述指定类型的子帧为几乎空白子帧ABS，此时，终端设备的传输资源为时域资源，终端设备的传输资源为ABS包括的全部PRB。
在这种情况下，第二基站接收到第一信息和第二信息后，会将终端设备的传输资源的资源位置对应的子帧配置为ABS，因此第二基站不会在该ABS上发送物理下行控制信道PDCCH消息和下行共享物理信道PDSCH消息，使得在该ABS上终端设备不会受到来自第二基站的业务和控制信道的干扰，因此可以实现降低终端设备受到的干扰。
另一种情况为：所述指定类型的子帧为多播/组播单频网络MBSFN子帧，此时，终端设备的传输资源为时域资源时，终端设备的传输资源为MBSFN子帧包括的全部PRB，终端设备的传输资源为频域资源时，终端设备的传输资源为MBSFN子帧包括的部分PRB。
在这种情况下，第二基站接收到第一信息和第二信息后，会将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧，因此第二基站将不会在该MBSFN子帧上发送导频信号，使得在该MBSFN子帧上终端设备不会受到来自第二基站的导频信号的干扰，因此可以实现降低终端设备受到的干扰。
在一种可能的实现方式中，所述第二信息用于指示所述传输资源的优先级级别时，所述第一基站还可以确定干扰信息，并向所述第二基站发送所述干扰信息。
其中，所述干扰信息包括但不限于以下信息之一或组合：所述第一基站的相对窄带发射功率RNTP、高干扰指示信息HII、负载指示信息OI。
这样，第二基站便可以基于第一信息、所述第二信息以及所述干扰信息进行动态ICIC，以更好地实现降低终端设备受到的干扰。
在一种可能的实现方式中，可通过如下两种方式实现所述第一基站向所述第二基站发送所述第一信息和所述第二信息：
第一种方式：第一基站可以通过与第二基站之间的通信接口，将第一信息和第二信息发送给第二基站。
其中，通信接口与第一基站或第二基站的制式相关，例如，第一基站与第二基站之间的通信接口可以为LTE系统中基站之间的X2接口，又例如，当第一基站和第二基站连接5G核心网时第一基站与第二基站之间的通信接口可以为5G系统中基站之间的Xn接口。
第二基站可以为第一基站的相邻基站，因此通过上述方法可以实现第一基站将第一信息和第二信息发送给相邻的第二基站。
第二种方式：第一基站可以通过核心网设备将第一信息和第二信息转发给第二基站。
示例性的，核心网设备可以为移动管理实体MME。第二基站可以不是第一基站的相邻基站，因此通过上述方法可以实现第一基站将第一信息和第二信息发送给非相邻的第二 基站。
在一种可能的实现方式中，所述终端设备为无人机终端。
由于无人机终端在空中飞行时能够搜索到更多的基站，因此无人机终端受到的小区干扰较为严重。通过上述方法可以实现降低无人机终端飞行时受到的来自其他基站的信号干扰。
第二方面，本申请实施例提供一种降低终端设备干扰的方法，包括：
第二基站从第一基站接收第一信息和第二信息，所述第一信息用于指示终端设备的传输资源的资源位置，所述第一基站为所述终端设备的服务基站；
当所述第二信息用于指示所述第二基站将所述资源位置对应的子帧配置为指定类型的子帧时，所述第二基站将所述资源位置对应的子帧配置为所述指定类型的子帧；或者，
当所述第二信息用于指示所述传输资源的优先级级别时，所述第二基站基于所述第一信息和所述第二信息进行动态小区间干扰协调ICIC。
其中，终端设备的传输资源是第一基站分配给该终端设备的专用传输资源，终端设备的传输资源可以是时域资源，也可以是频域资源。第二基站为对终端设备干扰较大的基站。
通过上述方法，第二基站接收到第一信息和第二信息后会根据第一信息和第二信息的指示，将所述资源位置对应的子帧配置为所述指定类型的子帧，或者基于第一信息和第二信息进行动态ICIC，进而减少第二基站使用终端设备的传输资源，从而使得终端设备在第一基站的覆盖范围内使用传输资源进行通信时受到第二基站的信号干扰大幅度降低。
在一种可能的实现方式中，所述第二信息用于指示第二基站将所述资源位置对应的子帧配置为指定类型的子帧时，包括如下两种情况：
一种情况为：所述指定类型的子帧为几乎空白子帧ABS，此时，终端设备的传输资源为时域资源，终端设备的传输资源为ABS包括的全部PRB。
在这种情况下，所述第二基站将所述资源位置对应的子帧配置为所述指定类型的子帧是指，第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS。因此第二基站不会在该ABS上发送物理下行控制信道PDCCH消息和下行共享物理信道PDSCH消息，使得在该ABS上终端设备不会受到来自第二基站的业务和控制信道的干扰，因此可以实现降低终端设备受到的干扰。
另一种情况为：所述指定类型的子帧为多播/组播单频网络MBSFN子帧，此时，终端设备的传输资源为时域资源时，终端设备的传输资源为MBSFN子帧包括的全部PRB，终端设备的传输资源为频域资源时，终端设备的传输资源为MBSFN子帧包括的部分PRB。
在这种情况下，所述第二基站将所述资源位置对应的子帧配置为所述指定类型的子帧是指，第二基站将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧，因此第二基站将不会在该MBSFN子帧上发送导频信号，使得在该MBSFN子帧上终端设备不会受到来自第二基站的导频信号的干扰，因此可以实现降低终端设备受到的干扰。
在一种可能的实现方式中，所述第二信息用于指示所述传输资源的优先级级别时，所述第二基站还会从所述第一基站接收干扰信息，然后基于所述干扰信息、所述第一信息和所述第二信息进行动态ICIC。
其中，所述干扰信息包括但不限于以下信息之一或组合：所述第一基站的相对窄带发射功率RNTP、高干扰指示信息HII、负载指示信息OI。
这样，第二基站在进行动态ICIC时可以基于第一信息、所述第二信息以及所述干扰 信息，以更好地实现降低终端设备受到的干扰。
在一种可能的实现方式中，可通过如下两种方式实现所述第二基站从第一基站接收第一信息和第二信息：
第一种方式：所述第二基站通过与所述第一基站之间的通信接口，接收所述第一信息和所述第二信息。
其中，通信接口与第一基站或第二基站的制式相关，例如，第一基站与第二基站之间的通信接口可以为LTE系统中基站之间的X2接口，又例如，当第一基站和第二基站连接5G核心网时第一基站与第二基站之间的通信接口可以为5G系统中基站之间的Xn接口。
第二基站可以为第一基站的相邻基站，因此通过上述方法可以实现第二基站从相邻的第一基站接收第一信息和第二信息。
第二种方式：所述第二基站接收核心网设备转发来自所述第一基站的所述第一信息和所述第二信息。
示例性的，核心网设备可以为移动管理实体MME。第二基站可以不是第一基站的相邻基站，因此通过上述方法可以实现第二基站从非相邻的第一基站接收第一信息和第二信息。
在一种可能的实现方式中，所述终端设备为无人机终端。
由于无人机终端在空中飞行时能够搜索到更多的基站，因此无人机终端受到的小区干扰较为严重。通过上述方法可以实现降低无人机终端飞行时受到的来自其他基站的信号干扰。

具体实施方式
在无线通信网络中，终端设备在其服务基站的覆盖范围内进行通信时会受到其他基站的信号干扰，这种终端设备通信时受到其他基站的信号干扰的现象在飞行终端设备上更加明显，其他基站包括终端设备的服务基站的相邻基站和非相邻基站。飞行终端设备通过无线通信网络在空中通信时会受到来自其他基站的较强的信号干扰，随着飞行终端设备的飞行高度升高，信号强度越来越强，而SINR干扰越来越强，并且飞行终端设备在空中通信时由于受到来自其他基站的较强的信号干扰而容易发生卡顿现象。
为了降低无线通信网络中终端设备在其服务基站的覆盖范围内进行通信时受到的来自其他基站的信号干扰，尤其是飞行终端设备，本申请实施例提供一种降低终端设备干扰的方法及基站。其中，方法和基站是基于同一发明构思的，由于方法及基站解决问题的原理相似，因此基站与方法的实施可以相互参见，重复之处不再赘述。
本申请实施例提供的技术方案适用于终端设备在服务基站的覆盖范围内进行通信的场景，以图1所示的一种网络架构示意图为例，图1中涉及终端设备101、第一基站102以及第二基站103，图1中仅示出一个第二基站103，第二基站103也可以为多个。其中，第一基站102为终端设备101提供服务，终端设备101在第一基站102的覆盖范围内进行通信，第一基站102即为终端设备101的服务基站；终端设备101在第一基站102的覆盖范围内进行通信时会受到来自第二基站103的信号干扰，第二基站103可以是第一基站102的相邻基站，第二基站103也可以不是第一基站102的相邻基站，本申请实施例中不做限定。本申请实施例提供的技术方案尤其适用于飞行终端设备在服务基站的覆盖范围内进行通信的场景，在此场景下，图1中终端设备101为飞行终端设备，由于飞行终端设备在飞行时视线传播无障碍，在空中能够看见更多的基站，因此更加会受到来自其他基站的信号干扰。
本申请实施例提供的技术方案可应用于多种通信系统。例如适用的系统可以是LTE系 统、第五代(5 th Generation，5G)系统、全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)通用分组无线业务(general packet radio service，GPRS)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动系统(universal mobile telecommunication system，UMTS)以及全球互联微波接入(worldwide interoperability for microwave access，WiMAX)系统等。
本申请实施例提供的技术方案中涉及终端设备和基站。其中，终端设备可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。在不同的系统中，终端设备的名称可能不相同。例如，终端设备也可以称为用户设备(user equipment，UE)。本申请实施例中终端设备可以是飞行终端设备，飞行终端设备也可以被称为其他名称，例如空中飞行器、无人机终端(drone UE)等。飞行终端设备可以是无人机上配备有蜂窝模块，也可以是无人机上携带有智能手机等通信设备。
根据具体应用场合不同，基站又可以称为接入点，或者可以是指接入网中在空中接口上与终端设备通信的设备，或者其它名称。基站可用于将收到的空中帧与网际协议(internet protocol，IP)分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)通信网络。基站还可协调对空中接口的属性管理。例如，本申请实施例涉及的基站可以是GSM或CDMA中的基站(base transceiver station，BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE系统中的演进型基站(evolutional node B，eNB或e-NodeB)、5G系统中的基站设备gNB，也可是家庭演进基站(home evolved node B，HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等，本申请实施例中并不限定。
下面对本申请实施例涉及名词进行解释。
几乎空白子帧(almost blank subframe，ABS)技术：ABS的特点是配置ABS的基站不能在该ABS上向终端设备发送物理下行控制信道(physical downlink control channel，PDCCH)消息和下行共享物理信道(physical downlink shared channel，PDSCH)消息，但配置ABS的基站可能会在该ABS上发送导频信号。使得除配置ABS的基站之外的其他基站可以在该ABS上进行调度。基站之间可以交互ABS信息，ABS信息用于指示基站将哪些下行子帧配置为ABS。
多播/组播单频网络(multimedia broadcast single frequency network or multicase broadcast single frequency network，MBSFN)技术：MBSFN要求同时传输来自多个小区的完全相同的波形，以使终端设备的接收机能够将多个MBSFN小区视为一个大的小区。此外，终端设备不仅不会受到相邻小区传输的小区间干扰，而且将受益于来自多个MBSFN小区的信号的叠加。本申请实施例中是利用MBSFN子帧的另一个特点，即配置MBSFN子帧的基站不能在该MBSFN子帧上发送导频信号，但配置MBSFN子帧的基站可能会在该MBSFN子帧上发送PDCCH消息和PDSCH消息。使得除配置MBSFN子帧的基站之外的其他基站可以在该MBSFN子帧上进行调度。
小区间干扰协调(Inter-Cell Interference Coordination，ICIC)技术：包括静态ICIC和动态ICIC。其中，
静态ICIC：将系统带宽分为A、B、C3份，每份占全频带的1/3。小区中心使用全频 带D，小区边缘使用1/3频带，静态ICIC的特点是边缘频带的大小固定，不能调整，即A、B、C为固定频带，如图2A所示。
动态ICIC：是对静态ICIC的改进，改进的方向就是小区边缘的1/3频带不是固定的，而是可以根据邻近小区间的负载情况进行调整，小区的边缘频带可以根据负载情况进行边缘频带扩张或收缩。当小区M的边缘用户较少时，小区M的边缘频带相对于静态ICIC将会减少，即少于1/3频带，同时小区M的邻近小区的边缘负载较重时，则邻近小区的边缘频带相对于静态ICIC将会增加，即多于1/3频带，如图2B所示。
开启动态ICIC之后，基站之间会交互各自的干扰信息，干扰信息包括以下信息之一或组合：相对窄带发射功率(relative narrowband tx power，RNTP)、高干扰指示信息(high-interference indicator，HII)、负载指示信息(overload indicator，OI)。基站根据其它基站的干扰信息进行ICIC估算，并根据ICIC估算结果决定位于小区边缘的频率资源是否使用高发射功率。ICIC估算结果将与用于基站实现资源调度，基于协作资源小区将根据每个终端设备的信道状态执行资源调度。由于每个小区都会根据邻近小区的协作资源执行资源调度，因此可以减小小区之间的干扰。
干扰信息中，RNTP用于指示频率资源，例如物理资源块(physical resource block，PRB)在下一个ICIC周期内在下行链路上是否使用高发射功率。RNTP的确定方法为：基站在当前ICIC周期内测量每一个RB在下行链路上的功率强度，例如可用比特表示功率强度，0表示功率强度低，1表示功率强度高，将当前ICIC周期内测量的功率强度的平均值作为进行RNTP。
HII用于指示频率资源在下一个ICIC周期内在上行链路上是否使用高发射功率。HII的确定方法为：基站在当前ICIC周期内测量每一个RB在上行链路上的功率强度，例如可用比特表示功率强度，0表示功率强度低，1表示功率强度高，将当前ICIC周期内测量的功率强度的平均值作为进行HII。
OI用于指示频率资源在最后一个ICIC周期内是否受到严重干扰。OI的确定方法为：基站在当前ICIC周期内测量每一个RB的干扰程度，干扰程度可分为高、中、低，将当前ICIC周期内每一个RB的干扰程度的平均值作为进行OI。
下面结合说明书附图对本申请各个实施例进行详细描述。需要说明的是，本申请实施例的展示顺序仅代表实施例的先后顺序，并不代表实施例所提供的技术方案的优劣。
本申请实施例提供一种降低终端设备干扰的方法，该方法中涉及第一基站、第二基站以及终端设备，其中第一基站为终端设备的服务基站，终端设备可以是无人机终端，第二基站与第一基站可以是相邻基站，也可以不是相邻基站。
在第一基站侧，如图3示出一种降低终端设备干扰的方法流程示意图，该方法包括：
步骤301：第一基站确定第一信息，该第一信息用于指示终端设备的传输资源的资源位置。
其中，终端设备的传输资源是第一基站分配给该终端设备的专用传输资源，终端设备的传输资源可以是静态配置或动态配置的，终端设备的传输资源可以是时域资源，也可以是频域资源，本实施例中并不限定。例如，传输资源为时域资源时，该时域资源的资源位置可以是指该时域资源对应的子帧的子帧号；又例如，传输资源为频域资源时，该频域资源的资源位置可以是指该频域资源对应的PRB的位置，该PRB可以是子帧中的部分PRB。
步骤302：第一基站确定第二信息，该第二信息用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为指定类型的子帧，或者该第二信息用于指示终端设备的传输资源的优先级级别。
本实施例中并不限定步骤301和步骤302的执行顺序，这两个步骤可以是分别执行也可以同时执行。分别执行步骤301和步骤302时，可以先执行步骤301后执行步骤302，也可以先执行步骤302后执行步骤301。
本实施例中，第二基站可以为一个或者多个，第二基站为多个时，第一基站与每个第二基站交互的方法均为图3所示的方法。第一基站可以通过如下方法确定第二基站：终端设备对除第一基站之外的其他基站进行测量，测量参数以下参数之一或组合：参考信号接收功率(reference signal received power，RSRP)、参考信号接收质量(reference signal received quality，RSRQ)以及SINR。第一基站获取终端设备对除第一基站之外的其他基站的测量结果，根据该测量结果筛选出可能会对终端设备干扰较大的一个或多个基站作为第二基站。需要说明的是，第二基站为对终端设备干扰较大的基站，本申请实施例中并不限定通过其他方法来确定第二基站。
步骤302中，当第二信息用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为指定类型的子帧时，在一种可能的实现方式中，指定类型的子帧为ABS，此时，终端设备的传输资源为时域资源，终端设备的传输资源为ABS包括的全部PRB。以终端设备的传输资源是子帧序号为0的子帧为例，第二信息指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS时，表示第二信息指示第二基站将序号为0的子帧配置为ABS。
由于配置ABS的基站不能在该ABS上向终端设备发送物理下行控制信道(physical downlink control channel，PDCCH)消息和下行共享物理信道(physical downlink shared channel，PDSCH)消息，因此如果第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS，则第二基站不会在该ABS上发送PDCCH消息和PDSCH消息，使得在该ABS上终端设备不会受到来自第二基站的业务和控制信道的干扰，但可能会受到来自第二基站的导频信号的干扰，因此可以实现降低终端设备受到的干扰。
步骤302中，当第二信息用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为指定类型的子帧时，在另一种可能的实现方式中，指定类型的子帧为MBSFN子帧，此时，终端设备的传输资源为时域资源时，终端设备的传输资源为MBSFN子帧包括的全部PRB，终端设备的传输资源为频域资源时，终端设备的传输资源为MBSFN子帧包括的部分PRB。以终端设备的传输资源是子帧序号为1的子帧包括的全部PRB为例，第二信息指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧时，表示第二信息指示第二基站将序号为1的子帧配置为MBSFN子帧。
由于配置MBSFN子帧的基站不能在该MBSFN子帧上发送导频信号，因此如果第二基站将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧，则第二基站将不会在该MBSFN子帧上发送导频信号，使得在该MBSFN子帧上终端设备不会受到来自第二基站的导频信号的干扰，但可能会受到来自第二基站的业务和控制信道的干扰，因此可以实现降低终端设备受到的干扰。
步骤302中，当第二信息用于指示终端设备的传输资源的优先级级别时，第二基站接收到上述第一信息和第二信息后，将会基于第一信息和第二信息进行动态ICIC，第二基 站基于第一信息和第二信息进行动态ICIC的方法将会在第二基站侧的方法中展开描述。本实施例中，当第二信息用于指示终端设备的传输资源的优先级级别时，可以将终端设备的传输资源的优先级级别配置为高，以便更好地实现第二基站避免使用终端设备的传输资源的目的。
可选的，当第二信息用于指示终端设备的传输资源的优先级级别时，第一基站还可以确定干扰信息，并将该干扰信息发送给第二基站。其中，干扰信息包括以下信息之一或组合：第一基站的RNTP、HII、OI。在此情况下，第一基站向第二基站发送的第一信息、第二信息以及干扰信息用于第二基站进行动态ICIC，第二基站基于第一信息、第二信息以及干扰信息进行动态ICIC的方法将会在第二基站侧的方法中展开描述。
步骤303：第一基站向第二基站发送第一信息和第二信息。
步骤303中，当第二基站为第一基站的相邻基站时，第一基站可以通过与第二基站之间的通信接口，将第一信息和第二信息发送给第二基站。本申请实施例对通信接口的类型不做任何限定，通信接口与第一基站或第二基站的制式相关。例如，第一基站与第二基站之间的通信接口可以为LTE系统中基站之间的X2接口，此时第一基站将携带有第一信息和第二信息的消息发送给第二基站，该消息可以为现有的X2接口消息，例如负载均衡(load information)消息，也可以是除X2接口消息之外新定义的消息。又例如，当第一基站和第二基站连接5G核心网时第一基站与第二基站之间的通信接口可以为5G系统中基站之间的Xn接口。
步骤303中，当第二基站不是第一基站的相邻基站时，第一基站可以通过核心网设备将第一信息和第二信息转发给第二基站。例如，第一基站连接演进型分组核心网(evolved packet core，EPC)时，第一基站可以通过与移动管理实体(mobile management entity，MME)之间的S1接口将携带有第一信息和第二信息的消息发送给MME，然后MME将该消息转发给第二基站，该消息可以为现有的S1接口消息，例如初始用户设备(initial UE message)消息，也可以是除S1接口消息之外新定义的消息。在此情况下，为了能够让核心网设备知道携带第一信息和第二信息的消息是发送给第二基站，该消息还需要携带第二基站的标识。
步骤303中，第一信息和第二信息可以是通过同一消息发送给第二基站，也可以是分别通过不同的消息发送给第二基站，本实施例中并不限定。
当第二信息用于指示终端设备的传输资源的优先级级别，以使第二基站进行动态ICIC时，第一基站将第一信息和第二信息发送给第二基站可能会存在延时，该延时应短于ICIC周期。
图3示出的方法中，第二信息所采用的方式包括但不限于如下三种：
方式一：第二信息包括第一指示位和第二指示位。其中，第一指示位取三种不同值时分别表示指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS，指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧，以及指示终端设备的传输资源的优先级级别；当第一指示位用于指示终端设备的传输资源的优先级级别时，第二指示位取不同的值表示终端设备的传输资源的优先级为不同的级别，当第一指示位用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS或者MBSFN子帧时，终端设备与基站(包括第一基站和第二基站)可以预定好不识别第二指示位，或者将第二指示位填充特殊的值，该特殊的值表示无需识别该第二指示位， 例如该特殊的值可以为00。
举例说明，假设资源的优先级级别分为高、中、低三种，第二信息可以为四位比特位组成的字符串。高两位比特组成第一指示位，高两位比特为00、01、10时分别表示指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS，指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧，以及指示终端设备的传输资源的优先级级别；低两位比特组成第二指示位，低两位比特为01、10、11时分别表示终端设备的传输资源的优先级级别分为高、中、低；当第一指示位用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS或者MBSFN子帧时，低两位比特为00。因此，第二信息为0000时，表示第二信息指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS；第二信息为0100时，表示第二信息指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧；第二信息为1001时，表示第二信息指示终端设备的传输资源的优先级级别为高；第二信息为1010时，表示第二信息指示终端设备的传输资源的优先级级别为中；第二信息为1011时，表示第二信息指示终端设备的传输资源的优先级级别为低。
方式二：第二信息的指示位取不同值时分别表示，指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS，指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧，以及指示终端设备的传输资源的优先级的不同级别。
举例说明，假设资源的优先级级别分为高、中、低三种，第二信息可以为三位比特位组成的字符串。第二信息为000时，表示第二信息指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS；第二信息为001时，表示第二信息指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧；第二信息为010时，表示第二信息指示终端设备的传输资源的优先级级别为高；第二信息为100时，表示第二信息指示终端设备的传输资源的优先级级别为中；第二信息为011时，表示第二信息指示终端设备的传输资源的优先级级别为低。
方式三：第一基站和第二基站预先协商好第二基站支持配置ABS、配置MBSFN子帧以及动态ICIC中的哪一种方案，其中第二基站支持动态ICIC的方案时需要第一基站通过第二信息向第二基站指示终端设备的传输资源的优先级级别。在此情况下，第二信息的指示位通过取不同值来指示第二基站是否使用第二基站支持的方案，第二信息用于指示终端设备的传输资源的优先级级别时，进一步的，第二信息的其他指示位通过取不同的值来指示终端设备的传输资源的优先级的不同级别。
举例说明，假设资源的优先级级别分为高、中、低三种，第二信息的指示位由三位比特组成，最高位为1表示第二基站使用第二基站支持的方案，最高位为0表示第二基站不使用第二基站支持的方案；低两位用于指示终端设备的传输资源的优先级的不同级别，其中11、10、01分别表示终端设备的传输资源的优先级为高、中、低。本实施例中，在第二基站支持配置ABS的情况下，当第二信息为100时，该第二信息用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS；在第二基站支持配置MBSFN子帧的情况下，当第二信息为100时，该第二信息用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧；在第二基站支持动态ICIC的情况下，当第二信息为111时，该第二信息用于指示终端设备的传输资源的优先级级别为高；在第二基站支持动态ICIC的情况下，当第二信息为110时，该第二信息用于指示终端设备 的传输资源的优先级级别为中；在第二基站支持动态ICIC的情况下，当第二信息为101时，该第二信息用于指示终端设备的传输资源的优先级级别为低。
需要说明的是，上述内容仅为第二信息可能采用的三种方式，本实施例中并不限定第二信息采用其他方式。
通过图3示出的方法，第一基站将第一信息和第二信息发送给第二基站，第二基站接收到第一信息和第二信息之后，会根据第一信息和第二信息的指示进行降低终端设备干扰的方法，第二基站侧降低终端设备干扰的方法将会在第二基站侧对应的图4示出的方法中展开描述。
在第二基站侧，如图4示出一种降低终端设备干扰的方法流程示意图，该方法包括：
步骤401：第二基站从第一基站接收第一信息和第二信息。
其中，第一信息用于指示终端设备的传输资源的资源位置；第二信息用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为指定类型的子帧，或者第二信息用于指示终端设备的传输资源的优先级级别。对于第一信息和第二信息的解释说明可参见上文步骤301和步骤302的相关内容，此处对于第一信息和第二信息不再赘述。
由于第二信息用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为指定类型的子帧，或者第二信息用于指示终端设备的传输资源的优先级级别，下面以第二信息指示的两种情况分别描述第二基站侧的方法，步骤402和步骤403为并列的两个步骤。
步骤402：当第二信息用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为指定类型的子帧时，第二基站将终端设备的传输资源的资源位置对应的子帧配置为指定类型的子帧。
步骤402中，当指定类型的子帧为ABS，即第二信息用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS时，第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS。可选的，第二基站配置ABS之后可以通知第一基站，第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS完成，该通知方法在实现时与步骤303中第一基站向第二基站发送第一信息和第二信息的实现方法类似，此处不再赘述。
第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS后，不会在该ABS上发送PDCCH消息和PDSCH消息，使得在该ABS上终端设备不会受到来自第二基站的业务和控制信道的干扰，但可能会受到来自第二基站的导频信号的干扰，因此可以实现降低终端设备受到的干扰。
步骤402中，当指定类型的子帧为MBSFN子帧，即第二信息用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧时，第二基站将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧，第二基站不会在配置的MBSFN子帧上发送导频信号。可选的，第二基站配置MBSFN子帧之后可以通知第一基站，第二基站将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧完成，该通知方法在实现时与步骤303中第一基站向第二基站发送第一信息和第二信息的实现方法类似，此处不再赘述。
第二基站将终端设备的传输资源的资源位置对应的子帧配置为MBSFN子帧后，不会在该MBSFN子帧上发送导频信号，使得在该MBSFN子帧上终端设备不会受到来自第二 基站的导频信号的干扰，但可能会受到来自第二基站的业务和控制信道的干扰，因此可以实现降低终端设备受到的干扰。
在一种可能的实现方式中，当第二信息用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS或MBSFN子帧时，第一基站也可以向第二基站指示终端设备的传输资源的优先级级别，此时第二基站会根据终端设备的传输资源的优先级级别进行资源调度，以使得第二基站更好的避开使用终端设备的传输资源。尤其是针对第二基站的负载很大的场景，第二信息用于指示第二基站将终端设备的传输资源的资源位置对应的子帧配置为ABS或MBSFN子帧，并且第一基站向第二基站指示终端设备的传输资源的优先级级别的方案，能够有效的避免第二基站使用终端设备的传输资源。
步骤403：当第二信息用于指示终端设备的传输资源的优先级级别时，第二基站基于第一信息和第二信息进行动态ICIC。
步骤403中，当第二基站接收的第二信息用于指示终端设备的传输资源的优先级级别时，由于终端设备的传输资源的优先级级别高，因此第二基站在进行动态ICIC时会避免使用该终端设备的传输资源。尤其是针对第二基站的负载很大的场景，采用现有的ICIC方案第二基站无法避免使用终端设备的传输资源，而本实施例中第一基站通过第二信息向第二基站指示终端设备的传输资源的优先级级别高，能够实现第二基站会避免使用该终端设备的传输资源。
可选的，第二基站除第一信息和第二信息之外还接收到第一基站发送的干扰信息，该干扰信息包括以下信息之一或组合：第一基站的RNTP、HII、OI。第二基站基于干扰信息、第一信息和第二信息进行动态ICIC，具体方法包括：如果第二信息指示终端设备的传输资源的优先级级别高，则第二基站会避免使用该终端设备的传输资源，或者第二基站通过干扰信息确定终端设备的传输资源中干扰严重的资源，在该干扰严重的资源上降低功率发射信号。需要说明的是，第二基站进行动态ICIC的方法与现有技术类似，此处不再赘述。
下面举例说明本实施例提供的一种降低终端设备干扰的方法。

步骤702：第一基站确定第二信息，该第二信息用于指示终端设备的传输资源的优先级级别。
步骤703：第一基站向第二基站发送第一信息和第二信息。
步骤704：第二基站从第一基站接收到第一信息和第二信息后，基于第一信息和第二信息进行动态ICIC。
在一种可能的实现方式中，步骤704之前，第一基站还可以向第二基站发送干扰信息，该干扰信息包括以下信息之一或组合：第一基站的RNTP、HII、OI。此时，步骤704中第二基站可以基于干扰信息、第一信息和第二信息进行动态ICIC。
