具体实施方式
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网络架构的示意图。该网络架构可以包括：多个接入网设备110和终端120。各个接入网设备110部署在RAN(Radio Access Network，无线接入网)10中。
终端120的数量通常为多个，每一个接入网设备110所管理的小区内可以分布一个或多个终端120。
接入网设备110与终端120之间通过某种空口技术互相通信，例如可以通过蜂窝技术相互通信。本公开实施例描述的技术方案可以适用于LTE系统，也可以适用于LTE系统后续的演进系统，如LTE-A(LTE-Advanced)系统、5G系统(也称为NR(New Radio)系统)等。
本公开实施例中，名词“网络”和“系统”经常交替使用，但本领域技术人员可以理解其含义。
本公开实施例所涉及到的终端可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为终端。
本公开实施例所涉及到的RAN中的接入网设备可以是基站(Base Station，BS)，所述基站是一种部署在RAN中用以为终端提供无线通信功能的装置。所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为演进的节点B(evolved NodeB，eNB或eNodeB)，在3G通信系统中，称为节点B(Node B)等等。随着通信技术的演进，“基站”这一名称可能会变化。为方便描述，本公开实施例中，上述为终端提供无线通信功能的装置统称为接入网设备。
为了提升无线信号的传输质量，引入波束成形(beamforming)技术，实现定向信号发送或接收。结合参考图2，图2是根据一示例性实施例示出的一种应用场景的示意图。该应用场景可以包括：第一接入网设备21、第二接入网设备22、第一终端23和第二终端24。其中，第一终端23位于第一接入网设备21服务的小区内，第二终端24位于第二接入网设备22服务的小区内。
如图2所示，第一接入网设备21可以包括多个天线，该多个天线能够产生多个不同指向的波束(beam)，覆盖第一接入网设备21所服务的小区。第一 接入网设备21可以通过波束向小区内的终端定向发送信号，也可以通过波束定向接收小区内的终端发送的信号。
类似地，第二接入网设备22也可以包括多个天线，该多个天线能够产生多个不同指向的波束，覆盖第二接入网设备22所服务的小区。第二接入网设备22可以通过波束向小区内的终端定向发送信号，也可以通过波束定向接收小区内的终端发送的信号。
如图2所示，当第一接入网设备21和第二接入网设备22邻近部署时，两者设备指向相同或接近的波束间，会存在较大的传输干扰。如图2所示，假设第一接入网设备21正在使用波束5和6向第一终端23发送下行数据，第二接入网设备22正在使用波束10和11向第二终端24发送下行数据，由于波束5和6与波束10和11的指向接近，因此第一终端23的接收会受到第二接入网设备22与第二终端24间的下行传输的干扰，第二终端24的接收也会受到第一接入网设备21与第一终端23间的下行传输的干扰。
另外，假设第一接入网设备21正在使用波束5和6接收第一终端23发送的上行数据，第二入网设备22正在使用波束10和11向第二终端24发送下行数据，第二终端24的接收也会受到第一终端23与第一接入网设备21间的上行传输的干扰。
如果设备(终端或接入网设备)在每一次进行数据传输前执行LBT流程进行干扰检测，LBT流程所涉及的CCA会给设备带来较大的处理开销。
在本公开实施例提供的技术方案中，通过接入网设备预存与相邻接入网设备的波束间的干扰互斥关系，并获取相邻接入网设备的波束占用情况，当接入网设备有数据传输需求时，根据上述波束占用情况以及预存的干扰互斥关系即可确定是否存在干扰，无需执行LBT流程进行CCA，简化了干扰检测流程，节省了设备的处理开销。
图3是根据一示例性实施例示出的一种干扰检测方法的流程图。该方法可应用于图2所示的应用场景中。该方法可以包括如下几个步骤。
在步骤301中，第二接入网设备接收第一接入网设备发送的波束占用信息。
波束占用信息用于指示第一接入网设备与第一终端之间传输第一数据所占用的第一波束。其中，第一波束的数量可以是1个，也可以是多个。第一数据可以包括第一接入网设备向第一终端发送的下行数据和/或第一终端向第一 接入网设备发送的上行数据。波束占用信息包括第一波束的标识信息。波束的标识信息用于唯一指示该波束，不同的波束对应不同的标识信息。可选地，波束的标识信息包括该波束对应的SSB(synchronization signal and PBCH Block，同步信号和物理广播信道块)索引，也即SSB index。例如，结合参考图2，假设第一接入网设备通过波束5向第一终端发送下行数据，则第一接入网设备向第二接入网设备发送的波束占用信息可以包括波束5的标识信息。
可选地，波束占用信息还包括时域指示信息和/或频域指示信息；其中，时域指示信息用于指示传输第一数据所占用的时域资源，频域指示信息用于指示传输第一数据所占用的频域资源。其中，时域资源可以包括所占用的帧、子帧、时隙、OFDM符号等时域单元的标识信息，也可以包括时域资源的占用时长。频域资源可以包括CC(Component Carrier，载波单元)、BWP(Bandwidth Part，一部分带宽)等频域单元的标识信息。
可选地，波束占用信息还包括传输类型指示信息；其中，传输类型指示信息用于指示第一数据对应的传输类型，传输类型包括上行传输和下行传输。上行传输是指终端向接入网设备发送数据，也即接入网设备从终端接收数据；下行传输是指接入网设备向终端发送数据，也即终端从接入网设备接收数据。
第二接入网设备可以通过空中接口接收第一接入网设备发送的波束占用信息，其中，上述空中接口可以是X2接口，也可以是与X2接口等效的空中接口。
在步骤302中，第二接入网设备确定与第一波束具有干扰互斥关系的第二波束。
可选地，第二接入网设备可以根据预存的干扰互斥信息，确定与第一波束具有干扰互斥关系的第二波束；其中，干扰互斥信息包括至少一组波束间的干扰互斥关系。可选地，第二接入网设备中预存的与第一接入网设备对应的干扰互斥信息，包括至少一组第一接入网设备的波束和第二接入网设备的波束之间的干扰互斥关系。在一个示例中，干扰互斥信息可以包括第二接入网设备与第一接入网设备间干扰最大的一组波束间的干扰互斥关系。在另一个示例中，干扰互斥信息可以包括第二接入网设备与第一接入网设备的波束间存在的所有干扰互斥关系。
上述干扰互斥关系可以在接入网设备部署时预设，也可以在接入网设备部署时，经初始化测量得到。
可选地，初始化测量过程如下：当第一接入网设备采用第一目标波束发送测量信号时，第二接入网设备采用第二目标波束接收测量信号，并获取该测量信号的接收信号强度；当测量信号的接收信号强度大于预设阈值时，第二接入网设备确定第二目标波束与第一目标波束具有干扰互斥关系；当测量信号的接收信号强度小于预设阈值时，第二接入网设备确定第二目标波束与第一目标波束不具有干扰互斥关系。可选地，接收信号强度可以用RSRP(Reference Signal Received Power，参考信号接收功率)值来衡量。另外，预设阈值可由协议预先规定，也可以在第二接入网设备中预先设定。若第二接入网设备确定第二目标波束与第一目标波束具有干扰互斥关系，则第二接入网设备记录第二目标波束与第一目标波束间的干扰互斥关系，例如将上述干扰互斥关系记录在干扰互斥信息中。
上述过程仅以确定一组波束间是否具有干扰互斥关系为例，对于其他波束间是否具有干扰互斥关系，可以采用相似的过程。可选地，结合参考图2，在初始化测量过程中，第一接入网设备21使用波束1发送测量信号，第二接入网设备22按波束编号顺序逐一开启波束1至波束12接收第一接入网设备21发送的测量信号，并获取测量信号的接收信号强度，完成第一轮测量。之后，第一接入网设备21使用波束2发送测量信号，第二接入网设备22再次按波束编号顺序逐一开启波束1至波束12接收第一接入网设备21发送的测量信号，并获取测量信号的接收信号强度，完成第二轮测量。之后，第一接入网设备21依次使用波束3至波束12，重复上述测量过程。至此，完成一次初始化测量。第二接入网设备22记录所有具有干扰互斥关系的各组波束。
另外，第二接入网设备可以根据已确定的具有干扰互斥关系的至少一组波束，以及第二接入网设备的波束分布和第一接入网设备的波束分布，确定第二接入网设备与第一接入网设备间具有干扰互斥关系的至少一组其它波束。可选地，上述波束分布可以包括波束的夹角和/或波束的指向。例如，第二接入网设备可以根据已确定的具有干扰互斥关系的波束，结合第二接入网设备的波束分布和第一接入网设备的波束分布，推算第二接入网设备与第一接入网设备指向相同或接近的波束组，并将上述指向相同或接近的波束组确定为具有干扰互斥关系的波束组。示例性地，结合参考图2，假设已经确定第一接入网设备21的波束5和第二接入网设备22的波束10具有干扰互斥关系，则根据波束的夹角，可以推算出，第一接入网设备21的波束6和第二接入网设备22的波束10 也具有干扰互斥关系。
另外，在本公开实施例中，对波束间的干扰互斥关系的记录方式不作限定。示例性地，结合参考图2，可以记录为如下形式：第一接入网设备：{波束5}<—>第二接入网设备：{波束11}，即表示第一接入网设备21的波束5与第二接入网设备22的波束11具有干扰互斥关系；或者，记录为如下形式：第一接入网设备：{波束5，波束6}<—>第二接入网设备：{波束10，波束11}，即表示第一接入网设备21的波束5和/或波束6与第二接入网设备22的波束10和/或波束11具有干扰互斥关系。
在步骤303中，若第二接入网设备存在使用第二波束与第二终端之间传输第二数据的需求，则第二接入网设备检测第二数据是否受到第一数据的传输干扰。
在一种可能的实施方式中，当第二接入网设备存在使用第二波束向第二终端发送第二数据的需求时，或者当第二接入网设备存在使用第二波束接收第二终端发送的第二数据的需求时，第二接入网设备均执行该检测第二数据是否受到第一数据的传输干扰的步骤。
在另一种可能的实施方式中，当第二接入网设备存在使用第二波束向第二终端发送第二数据的需求时，第二接入网设备执行该检测第二数据是否受到第一数据的传输干扰的步骤；当第二接入网设备存在使用第二波束接收第二终端发送的第二数据的需求时，第二接入网设备不执行该检测第二数据是否受到第一数据的传输干扰的步骤。由于第一接入网设备与第一终端之间的传输，对第二接入网设备的上行接收干扰较小，因此第二接入网设备可以仅在有下行传输的需求时进行干扰检测，而在有上行传输的需求时不进行干扰检测，直接认为不会受到干扰。
在本公开实施例中，第二接入网设备检测第二数据是否受到第一数据的传输干扰，可以采用如下方式：第二接入网设备检测第二数据是否符合干扰判定条件；当第二数据符合干扰判定条件时，第二接入网设备确定第二数据受到第一数据的传输干扰；反之，当第二数据不符合干扰判定条件时，第二接入网设备确定第二数据没有受到第一数据的传输干扰。
可选地，干扰判定条件包括：传输第二数据计划占用的时域资源与传输第一数据所占用的时域资源存在重叠，且传输第二数据计划占用的频域资源与传输所述第一数据所占用的频域资源也存在重叠。
第二接入网设备可以采用如下方式，获取传输第一数据所占用的时域资源和/或频域资源：第二接入网设备从第一接入网设备发送的波束占用信息中，获取时域指示信息和/或频域指示信息，据此确定传输第一数据所占用的时域资源和/或频域资源。另外，在其它可能的实施方式中，第二接入网设备还可以从其它设备或根据默认配置，确定传输第一数据所占用的时域资源和/或频域资源。
另外，传输第二数据计划占用的时域资源和频域资源，可以由第二接入网设备自己确定。
可选地，干扰判定条件还包括：第一数据对应的传输类型为上行传输。也即只有在第一接入网设备使用第一波束进行上行传输时，第二接入网设备才检测第二数据是否受到第一数据的传输干扰；当第一接入网设备使用第一波束进行下行传输时，第二接入网设备不检测第二数据是否受到第一数据的传输干扰。
示例性地，结合参考图2，当第一接入网设备21使用波束5向第一终端23下行发送第一数据时，若第二接入网设备22需要使用波束11向第二终端24下行发送第二数据，则第二接入网设备22确定第二数据不受第一数据的传输干扰。当第一接入网设备21使用波束5接收第一终端23上行发送的第一数据时，若第二接入网设备22需要使用波束11向第二终端24下行发送第二数据，则第二接入网设备22确定第二数据受到第一数据的传输干扰。
另外，第二接入网设备可以根据第一接入网设备向其发送的波束占用信息中所携带的传输类型指示信息，确定第一数据对应的传输类型。
在其它可能的实施方式中，当第一接入网设备下行传输第一数据时，第一接入网设备不向第二接入网设备发送波束占用信息；当第一接入网设备上行接收第一数据时，第一接入网设备向第二接入网设备发送波束占用信息。
可选地，当第二接入网设备确定第二数据受到第一数据的传输干扰时，第二接入网设备不执行LBT流程，按照第二数据的传输信道已被占用处理。第二接入网设备可以重新规划传输第二数据所计划占用的时频资源，以避免其与第一数据产生传输干扰。
可选地，当第二接入网设备确定第二数据未受到第一数据的传输干扰时，第二接入网设备可以执行LBT流程，以确定第二数据是否满足传输条件。当第二数据满足上述传输条件时，第二接入网设备按照传输第二数据计划占用的时频资源，在第二接入网设备和第二终端间传输第二数据。进一步地，当第二 接入网设备确定第二数据未受到第一数据的传输干扰时，第二接入网设备也可以不执行LBT流程，直接执行按照传输第二数据计划占用的时频资源，在第二接入网设备和第二终端间传输所述第二数据的步骤，从而可以实现完全不通过LBT流程进行干扰检测。
需要说明的一点是，当第二接入网设备进行数据传输时，也可以向其相邻接入网设备发送波束占用信息，其相邻接入网设备也可以进行上述干扰检测。
综上所述，本公开实施例提供的技术方案中，通过接入网设备预存与相邻接入网设备的波束间的干扰互斥关系，并获取相邻接入网设备的波束占用情况，当接入网设备有数据传输需求时，根据上述波束占用情况以及预存的干扰互斥关系即可确定是否存在干扰，无需执行LBT流程进行CCA，简化了干扰检测流程，节省了设备的处理开销。
