信号干扰协调方法、通信装置及计算机可读存储介质

具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
本申请实施例可应用于各种类型的通信系统。图1为本申请实施例提供的一种应用场景示意图。如图1所示的通信系统，主要包括网络设备11和终端设备12。
其中，1)网络设备11可以是网络侧设备，例如，无线局域网(Wireless Local Area Network，WLAN)的接入点(Access Point，AP)、4G的演进型基站(Evolved Node B，eNB或eNodeB)、5G的新无线接入技术(New Radio Access Technology，NR)基站(next generation Node B，gNB)、下一代通信的基站、卫星、小站、微站、中继站、发送和接收点(Transmission and Reception Point，TRP)、路边单元(Road Side Unit，RSU)等。为了区别起见，将4G通信系统的基站称为长期演进(Long Term Evolution，LTE)eNB，5G通信系统的基站称为NR gNB。可以理解的是，一些基站既可以支持4G通信系统又可以支持5G通信系统。另外，基站的这些名称仅为了方便区别，并不具有限制意义。
2)终端设备12又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备、具有车与车(vehicle to vehicle，V2V)通信能力的车辆等。常见的终端设备例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
3)“多个”是指两个或两个以上，其它量词与之类似。“和/或”，描述关联对象的对应关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
需要说明的是，图1所示的通信系统中所包含的终端设备12的数量和类型仅仅是一种举例，本申请实施例并不限制于此。例如，还可以包括更多的与网络设备11进行通信的终端设备12，为简明描述，不在附图中一一描述。此外，在如图1所示的通信系统中，尽管示出了网络设备11和终端设备12，但是该通信系统可以并不限于包括网络设备11和终端设备12，例如还可以包括核心网节点或用于承载虚拟化网络功能的设备等，这些对于本领域技术人员而言是显而易见的，在此不一一赘述。
另外，本申请实施例不仅可应用于4G无线通信系统、车对外界(vehicle to everything，V2X)通信系统、设备到设备(Device-to-Device，D2D)通信系统、LTE的后续演化通信系 统、5G通信系统、卫星通信系统等通信系统，还可应用于下一代无线通信系统。另外，本申请实施例还可以应用于未来可能出现的其他系统,例如下一代的wifi网络、5G车联网等。
需要说明的是，随着通信系统的不断演进，未来可能出现的其他系统中，上述各个网元的名称可能会发生变化，在这种情况下，本申请实施例提供的方案同样适用。
在本申请实施例中，网络设备和终端设备之间可采用OAM波进行通信。OAM波具体可以是在正常的无线电磁波的基础上增加一个相位因子，其中，正常的无线电磁波幅度可记为A(r)，r表示光心到波束中心轴线的辐射距离。相位因子可记为
Figure PCTCN2020127946-appb-000001
i表示虚数单位，
Figure PCTCN2020127946-appb-000002
表示方位角，l表示无线电磁波的OAM模态信息，OAM模态信息可用于标识OAM模态，例如，不同的OAM模态信息可对应不同的OAM模态，即OAM模态信息和OAM模态可以是一一对应的。增加相位因子
Figure PCTCN2020127946-appb-000003
后的无线电磁波可表示为
Figure PCTCN2020127946-appb-000004
当l＝0时，
Figure PCTCN2020127946-appb-000005
具体为正常的无线电磁波，该无线电磁波的波前是平面结构。当l≠0时，
Figure PCTCN2020127946-appb-000006
具体为OAM波，OAM波的波前将不再是平面结构，而是可以绕着波束传播方向旋转，变换为螺旋相位波前结构。其中，OAM模态信息l可以是一个不受限的整数，不同OAM模态信息对应的OAM波的波前结构也是不一样的。如图2所示为l＝0的无线电磁波的波前结构，如图3所示为l＝1的OAM波的波前结构，如图4所示为l＝2的OAM波的波前结构，如图5所示为l＝3的OAM波的波前结构。由此可见，OAM模态信息l≠0的相位因子可使得无线电磁波具有螺旋状的非平面波前结构。
通常情况下，相邻小区间的数据会彼此干扰，一种可能的干扰情况是：相邻小区间的上行数据彼此干扰，和/或相邻小区间的下行数据彼此干扰。另一种可能的干扰情况是：相邻小区间的上行数据和下行数据之间彼此干扰。
如图6所示，小区61和小区71是相邻小区，网络设备62是小区61中的网络设备，终端设备63是小区61中的边缘终端设备。网络设备72是小区71中的网络设备，终端设备73是小区71中的边缘终端设备。具体的，网络设备62采用OAM模态信息l对应的OAM模态向终端设备63发送下行数据，网络设备72也采用相同的OAM模态信息l对应的OAM模态向终端设备73发送下行数据，如此会导致网络设备62向终端设备63发送的下行数据与网络设备72向终端设备73发送的下行数据之间彼此干扰。例如，如图6所示，网络设备62向终端设备63发送的下行数据可能会被终端设备73接收到，网络设备72向终端设备73发送的下行数据可能会被终端设备63接收到。
如图7所示，终端设备63采用OAM模态信息l对应的OAM模态向网络设备62发送上行数据，终端设备73也采用OAM模态信息l对应的OAM模态向网络设备72发送上行数据，如此会导致终端设备63向网络设备62发送的上行数据与终端设备73向网络设备72发送的上行数据之间彼此干扰。例如，如图7所示，终端设备63向网络设备62发送的上行数据可能会被网络设备72接收到，终端设备73向网络设备72发送的上行数据可能会被网络设备62接收到。
此外，如图6或图7所示，如果终端设备63发送上行数据所采用的OAM模态与终端设备73接收下行数据所采用的OAM模态相同，如此会导致小区61中的上行数据与小区71中的下行数据之间彼此干扰。如果终端设备63接收下行数据所采用的OAM模态与终端设备73发送上行数据所采用的OAM模态相同，如此会导致小区61中的下行数据与小区71中的上行数据之间彼此干扰。
也就是说，如果相邻小区间的网络设备采用相同OAM模态的OAM波向各自小区中的边缘终端设备发送下行数据，和/或相邻小区间各小区的边缘终端设备采用相同OAM模态的OAM波向各自的网络设备发送上行数据，可能会导致相邻小区间的上行数据彼此干扰，和/或相邻小区间的下行数据彼此干扰。如果相邻小区间的网络设备发送下行数据采用的OAM模态与相邻小区间各小区的边缘终端设备发送上行数据采用的OAM模态相同，可能会导致相邻小区间的上行数据和下行数据之间彼此干扰从而降低了信号传输的可靠性，导致数据传输错误。为了解决该问题，本申请实施例提供了一种信号干扰协调方法，下面结合实施例对该信号干扰协调方法进行详细的描述。
本实施例所述的信号干扰协调方法可适用于如图8所示的应用场景。如图8所示，小区81、小区82和小区83是相邻的蜂窝小区。每个小区包括一个或多个终端设备。若某个小区包括多个终端设备，则该小区中的多个终端设备可分为边缘终端设备和中心终端设备。以小区81为例，终端设备1、终端设备2、终端设备3、终端设备4、终端设备5、终端设备6、终端设备7、终端设备8、终端设备9为小区81中的边缘终端设备。该小区中的中心终端设备可位于中心区域80中。也就是说，该小区中的中心终端设备距离该小区的网络设备较近，中心终端设备和网络设备之间的信号较好。该小区中的边缘终端设备距离该小区的网络设备较远，边缘终端设备和网络设备之间的信号较差。下面结合如图8所示的应用场景对该信号干扰协调方法进行介绍。
图9为本申请实施例提供的一种信号干扰协调方法流程图。如图9所示，本实施例所述的信号干扰协调方法包括如下步骤：
S91、网络设备获取第一终端设备对应的上行OAM模态信息和/或下行OAM模态信息。
在本实施例中，网络设备例如可以是如图8所示的小区81中的网络设备84，第一终端设备例如可以是如图8所示的小区81中的终端设备1。网络设备84可获取终端设备1对应的上行OAM模态信息和/或下行OAM模态信息。在一种可能的方式中，网络设备84可预先存储有小区81中各个边缘终端设备对应的上行OAM模态信息和/或下行OAM模态信息，该网络设备84可从预先存储的信息中获取终端设备1对应的上行OAM模态信息和/或下行OAM模态信息。在另一种可能的方式中，网络设备84可从一个备选的集合中选取终端设备1对应的上行OAM模态信息和/或下行OAM模态信息，该备选的集合可以是小区81支持的OAM模态对应的OAM模态信息构成的集合，或者该备选的集合是该小区81支持的OAM模态对应的OAM模态信息构成的集合的子集。
S92、网络设备向第一终端设备发送第一终端设备对应的上行OAM模态信息和/或下行OAM模态信息，相应的，第一终端设备从该网络设备接收该第一终端设备对应的上行OAM模态信息和/或下行OAM模态信息。
例如，网络设备84向终端设备1发送终端设备1对应的上行OAM模态信息和/或下行OAM模态信息。相应的，终端设备1从网络设备84接收终端设备1对应的上行OAM模态信息和/或下行OAM模态信息。或者，终端设备1可以预先存储有终端设备1对应的上行OAM模态信息和/或下行OAM模态信息，当终端设备1发送上行数据时从预先存储的信息中获取该终端设备1对应的上行OAM模态信息。当终端设备1接收下行数据时从预先存储的信息中获取该终端设备1对应的下行OAM模态信息。
S93、第一终端设备采用该第一终端设备对应的上行OAM模态信息向该网络设备发送上行数据，相应的，该网络设备接收该上行数据。
具体的，终端设备1可以根据该终端设备1对应的上行OAM模态信息确定上行OAM模态，该上行OAM模态可用于终端设备1发送上行数据。
例如，终端设备1向网络设备84发送上行数据时，该终端设备1采用信道编码对该上行数据进行编码，将信道编码后的上行数据通过星座调制后传输给网络设备84，传输方式采用OAM波进行传输，并且该OAM波的OAM模态为该终端设备1对应的上行OAM模态。网络设备84接收该终端设备1采用该终端设备1对应的上行OAM模态发送的上行数据。
S94、网络设备采用该第一终端设备对应的下行OAM模态信息向该第一终端设备发送下行数据，相应的，该第一终端设备根据该第一终端设备对应的下行OAM模态信息接收该下行数据。
具体的，终端设备1可以根据该终端设备1对应的下行OAM模态信息确定下行OAM模态，该下行OAM模态可用于终端设备1接收下行数据。
例如，网络设备84向终端设备1发送下行数据时，网络设备84采用信道编码对该下行数据进行编码，将信道编码后的下行数据通过星座调制后传输给终端设备1，传输方式采用OAM波进行传输，并且该OAM波的OAM模态为该终端设备1对应的下行OAM模态。终端设备1根据该终端设备1对应的下行OAM模态接收该下行数据。
可以理解的是，S93和S94可以同时存在，也可以不同时存在，例如，在一些实施例中可以包括如上所述的S91、S92、S93。在另一些实施例中可以包括如上所述的S91、S92、S94。在其他一些实施例中可以包括如上所述的S91、S92、S93、S94。
另外，如图8所示，终端设备12和终端设备13是小区82中的边缘终端设备，终端设备12和终端设备13分别与小区81中的终端设备1相邻。在本申请实施例中可以将小区81记为第一小区，将小区81中的终端设备1记为第一终端设备。将小区82记为第二小区，将小区82中的终端设备12和终端设备13分别记为第二终端设备。可以理解的是，如图8所示的小区81和小区82只是一种示意性说明，并不限定每个小区中的边缘终端设备的个数和位置，也不限定如上所述的第一终端设备的个数和第二终端设备的个数。例如，在一些实施例中，第二终端设备的个数可以是一个。
另外，不同OAM模态的OAM波相互之间是正交的，也就是说，若任意两个OAM波的OAM模态不同，则这两个OAM波是正交的，如此可以避免两个OAM波相互干扰。
在一种可能的方式中，第一终端设备对应的上行OAM模态信息与至少一个第二终端设备对应的上行OAM模态信息不同，和/或第一终端设备对应的下行OAM模态信息与至少一个第二终端设备对应的下行OAM模态信息不同，如此可以避免相邻小区间的上行数据彼此干扰，和/或相邻小区间的下行数据彼此干扰。
以图8所示的终端设备1、终端设备12和终端设备13为例，基于OAM波的上行传输中，在终端设备1、终端设备12和终端设备13采用的其他传输方式或传输形式相同的情况下，通过终端设备1对应的上行OAM模态信息与终端设备12对应的上行OAM模态信息不同，和/或终端设备1对应的上行OAM模态信息与终端设备13对应的上行OAM模态信息不同，可使得终端设备12和/或终端设备13发送上行数据所采用的上行OAM模态 与终端设备1发送上行数据所采用的上行OAM模态不同，从而可避免终端设备12和/或终端设备13向网络设备85发送的上行数据与终端设备1向网络设备84发送的上行数据之间彼此干扰，也就是说，可避免相邻小区间的上行数据彼此干扰。其中，其他传输方式或传输形式包括传输时间、频域资源、采用多输入多输出(Multi Input Multi Output，MIMO)技术时相应的码本。
基于OAM波的下行传输中，在终端设备1、终端设备12和终端设备13采用的其他传输方式或传输形式相同的情况下，通过终端设备1对应的下行OAM模态信息与终端设备12对应的下行OAM模态信息不同，和/或终端设备1对应的下行OAM模态信息与终端设备13对应的下行OAM模态信息不同，可使得终端设备12和/或终端设备13接收下行数据所采用的下行OAM模态与终端设备1接收下行数据所采用的下行OAM模态不同，从而可避免网络设备85向终端设备12和/或终端设备13发送的下行数据与网络设备84向终端设备1发送的下行数据之间彼此干扰，也就是说，可避免相邻小区间的下行数据彼此干扰。
可以理解的是，当第一终端设备(例如，终端设备1)对应的上行OAM模态信息与至少一个第二终端设备(例如，终端设备12和终端设备13)对应的上行OAM模态信息不同，和/或第一终端设备对应的下行OAM模态信息与至少一个第二终端设备对应的下行OAM模态信息不同时，第一终端设备和至少一个第二终端设备采用的其他传输方式或传输形式可以相同，也可以不同。
本实施例通过第一小区中的第一终端设备对应的上行OAM模态信息与第二小区中的至少一个第二终端设备对应的上行OAM模态信息不同，可使得第一终端设备发送上行数据时采用的OAM波与至少一个第二终端设备发送上行数据时采用的OAM波彼此正交，从而避免了属于不同小区且相邻的终端设备之间的上行数据之间的相互干扰；和/或通过第一小区中的第一终端设备对应的下行OAM模态信息与第二小区中的至少一个第二终端设备对应的下行OAM模态信息不同，可使得相邻小区间的不同网络设备在发送下行数据时采用的OAM波彼此正交，从而避免了相邻小区间下行数据之间的相互干扰，从而提高了信号传输的可靠性，避免数据传输错误。
作为上述实施例的一种可替换方式，第一终端设备对应的上行OAM模态信息与至少一个第二终端设备对应的下行OAM模态信息不同，和/或第一终端设备对应的下行OAM模态信息与至少一个第二终端设备对应的上行OAM模态信息不同，如此可以避免相邻小区间的上行数据和下行数据之间彼此干扰。
如图8所示，在终端设备1、终端设备12和终端设备13采用的其他传输方式或传输形式相同的情况下，通过终端设备1对应的上行OAM模态信息与终端设备12对应的下行OAM模态信息不同，和/或终端设备1对应的上行OAM模态信息与终端设备13对应的下行OAM模态信息不同，可使得终端设备12和/或终端设备13接收下行数据所采用的下行OAM模态与终端设备1发送上行数据所采用的上行OAM模态不同，从而可避免终端设备1向网络设备84发送的上行数据与网络设备85向终端设备12和/或终端设备13发送的下行数据之间彼此干扰，也就是说，可避免相邻小区间上行数据和下行数据之间的干扰。
另外，在终端设备1、终端设备12和终端设备13采用的其他传输方式或传输形式相同的情况下，通过终端设备1对应的下行OAM模态信息与终端设备12对应的上行OAM 模态信息不同，和/或终端设备1对应的下行OAM模态信息与终端设备13对应的上行OAM模态信息不同，可使得终端设备12和/或终端设备13发送上行数据所采用的上行OAM模态与终端设备1接收下行数据所采用的下行OAM模态不同，从而可避免终端设备12和/或终端设备13向网络设备85发送的上行数据与网络设备84向终端设备1发送的下行数据之间彼此干扰，也就是说，可避免相邻小区间上行数据和下行数据之间的干扰。
可以理解的是，当第一终端设备(例如，终端设备1)对应的上行OAM模态信息与至少一个第二终端设备(例如，终端设备12和终端设备13)对应的下行OAM模态信息不同，和/或第一终端设备对应的下行OAM模态信息与至少一个第二终端设备对应的上行OAM模态信息不同时，第一终端设备和至少一个第二终端设备采用的其他传输方式或传输形式可以相同，也可以不同。
本实施例通过第一小区中的第一终端设备对应的上行OAM模态信息与第二小区中的至少一个第二终端设备对应的下行OAM模态信息不同，可使得第一终端设备发送上行数据时采用的OAM波与第二小区中的网络设备发送下行数据时采用的OAM波彼此正交，从而避免了相邻小区间上行数据与下行数据之间的相互干扰；和/或通过第一小区中的第一终端设备对应的下行OAM模态信息与第二小区中的至少一个第二终端设备对应的上行OAM模态信息不同，可使得第一小区中的网络设备发送下行数据时采用的OAM波与至少一个第二终端设备发送上行数据时采用的OAM波彼此正交，从而避免了相邻小区间下行数据与上行数据之间的相互干扰，提高了信号传输的可靠性，避免数据传输错误。
可以理解的是，上述实施例所述的“第一终端设备对应的上行OAM模态信息与至少一个第二终端设备对应的上行OAM模态信息不同，和/或第一终端设备对应的下行OAM模态信息与至少一个第二终端设备对应的下行OAM模态信息不同”这种方式与“第一终端设备对应的上行OAM模态信息与至少一个第二终端设备对应的下行OAM模态信息不同，和/或第一终端设备对应的下行OAM模态信息与至少一个第二终端设备对应的上行OAM模态信息不同”这种方式可以是相互独立的，即并列关系。另外，这两种方式也可以是相互关联的，例如，在前一种方式的基础上增加后一种方式，或者是在后一种方式的基础上增加前一种方式。上述实施例以这两种方式是相互独立的为例进行示意性说明，下面实施例将介绍这两种方式相互关联的情况。
例如，在“第一终端设备对应的上行OAM模态信息与至少一个第二终端设备对应的上行OAM模态信息不同，和/或第一终端设备对应的下行OAM模态信息与至少一个第二终端设备对应的下行OAM模态信息不同”的基础上，进一步还可以有“第一终端设备对应的上行OAM模态信息与至少一个第二终端设备对应的下行OAM模态信息不同，和/或第一终端设备对应的下行OAM模态信息与至少一个第二终端设备对应的上行OAM模态信息不同”。
如图8所示，在终端设备1、终端设备12和终端设备13采用的其他传输方式或传输形式相同的情况下，终端设备1对应的上行OAM模态信息与终端设备12和/或终端设备13对应的上行OAM模态信息不同，终端设备1对应的下行OAM模态信息与终端设备12和/或终端设备13对应的下行OAM模态信息不同，如此可避免相邻小区间的上行数据彼此干扰，以及避免相邻小区间的下行数据彼此干扰。在此基础上，还可以通过终端设备1对应的上行OAM模态信息与终端设备12和/或终端设备13对应的下行OAM模态信息不 同，终端设备1对应的下行OAM模态信息与终端设备12和/或终端设备13对应的上行OAM模态信息不同，进一步避免相邻小区间的上行数据和下行数据之间彼此干扰，从而可以进一步提高信号传输的可靠性，避免数据传输错误。
此外，如图8所示，终端设备2与终端设备1在同一小区内、且终端设备2与终端设备1相邻，此处，可以将终端设备2记为第三终端设备。可以理解的是，在小区81中，与终端设备1相邻的终端设备可以不止一个，也就是说，第三终端设备可以是一个或多个。为了避免终端设备12和/或终端设备13发送的上行数据与终端设备2发送的上行数据相互干扰，终端设备12和/或终端设备13对应的上行OAM模态信息与终端设备2对应的上行OAM模态信息可以不同。为了避免终端设备12和/或终端设备13接收的下行数据与终端设备2接收的下行数据相互干扰，终端设备12和/或终端设备13对应的下行OAM模态信息与终端设备2对应的下行OAM模态信息可以不同。同理，为了避免终端设备12和/或终端设备13发送的上行数据与终端设备2接收的下行数据相互干扰，终端设备12和/或终端设备13对应的上行OAM模态信息与终端设备2对应的下行OAM模态信息可以不同。为了避免终端设备12和/或终端设备13接收的下行数据与终端设备2发送的上行数据相互干扰，终端设备12和/或终端设备13对应的下行OAM模态信息与终端设备2对应的上行OAM模态信息可以不同。
上述实施例介绍了不同小区间相邻终端设备的上行OAM模态信息和/或下行OAM模态信息，本实施例将介绍同一小区内相邻终端设备的上行OAM模态信息和/或下行OAM模态信息。例如小区81中的终端设备1和终端设备2分别对应的上行OAM模态信息和/或下行OAM模态信息。
在终端设备1和终端设备2采用的其他传输方式或传输形式相同的情况下，通过终端设备1对应的上行OAM模态信息与终端设备2对应的上行OAM模态信息不同，可使得终端设备1发送上行数据所采用的上行OAM模态与终端设备2发送上行数据所采用的上行OAM模态不同，从而可避免同一小区内终端设备1发送的上行数据和终端设备2发送的上行数据之间彼此干扰。同理，通过终端设备1对应的下行OAM模态信息与终端设备2对应的下行OAM模态信息不同，可使得终端设备1接收下行数据所采用的下行OAM模态与终端设备2接收下行数据所采用的下行OAM模态不同，从而可避免同一小区内终端设备1接收的下行数据和终端设备2接收的下行数据之间彼此干扰。
可以理解的是，同一小区内，终端设备1和终端设备2分别对应的上行OAM模态信息可以相同，和/或终端设备1和终端设备2分别对应的下行OAM模态信息可以相同，此时需要终端设备1和终端设备2采用的其他传输方式或传输形式不同，例如，传输时间、频域资源、采用MIMO技术时相应的码本中的至少一个不同。
同理，在终端设备1和终端设备2采用的其他传输方式或传输形式相同的情况下，通过终端设备1对应的上行OAM模态信息与终端设备2对应的下行OAM模态信息不同，可使得终端设备1发送上行数据所采用的上行OAM模态与终端设备2接收下行数据所采用的下行OAM模态不同，从而可避免同一小区内终端设备1发送的上行数据和终端设备2接收的下行数据之间彼此干扰。同理，通过终端设备1对应的下行OAM模态信息与终端设备2对应的上行OAM模态信息不同，可使得终端设备1接收下行数据所采用的下行OAM模态与终端设备2发送上行数据所采用的上行OAM模态不同，从而可避免同一小区 内终端设备1接收的下行数据和终端设备2发送的上行数据之间彼此干扰。
可以理解的是，同一小区内，终端设备1对应的上行OAM模态信息和终端设备2对应的下行OAM模态信息可以相同，和/或终端设备1对应的下行OAM模态信息和终端设备2对应的上行OAM模态信息可以相同，此时需要终端设备1和终端设备2采用的其他传输方式或传输形式不同，例如，传输时间、频域资源、采用MIMO技术时相应的码本中的至少一个不同。
本实施例通过同一小区内的第一终端设备对应的上行OAM模态信息与第三终端设备对应的上行OAM模态信息不同，可使得第一终端设备发送上行数据时采用的OAM波与第三终端设备发送上行数据时采用的OAM波彼此正交，从而避免了属于同一小区且相邻的终端设备之间的上行数据之间的相互干扰。通过同一小区内的第一终端设备对应的下行OAM模态信息与第三终端设备对应的下行OAM模态信息不同，可使得同一小区内的网络设备向该小区中相邻的终端设备发送下行数据时采用的OAM波彼此正交，从而避免了同一小区中下行数据之间的相互干扰。另外，还可以通过同一小区内的第一终端设备对应的上行OAM模态信息与第三终端设备对应的下行OAM模态信息不同，避免同一小区内第一终端设备向网络设备发送的上行数据与该网络设备向第三终端设备发送的下行数据之间的相互干扰。此外，通过同一小区内的第一终端设备对应的下行OAM模态信息与第三终端设备对应的上行OAM模态信息不同，还可以避免同一小区内网络设备向第一终端设备发送的下行数据与第三终端设备向该网络设备发送的上行数据之间的相互干扰。从而提高了同一小区内信号传输的可靠性，避免数据传输错误。
可以理解的是，对于同一个终端设备而言，该终端设备对应的上行OAM模态信息和该终端设备对应的下行OAM模态信息可以相同，也可以不同。当该终端设备对应的上行OAM模态信息和该终端设备对应的下行OAM模态信息不同时，可避免同一终端设备的上行数据和下行数据之间相互干扰。若该终端设备对应的上行OAM模态信息和该终端设备对应的下行OAM模态信息相同，可通过其他方式避免同一终端设备的上行数据和下行数据之间相互干扰，例如，该终端设备可以分时发送上行数据、接收下行数据。
另外，如上所述的第二小区还可以是如图8所示的小区83，如上所述的第二终端设备还可以是如图8所示的小区83中的终端设备10和终端设备11，在这种情况下，第一终端设备可以是如图8所示的小区81中的终端设备8，终端设备10和终端设备11分别与终端设备8相邻，第三终端设备可以是如图8所示的小区81中的终端设备9，终端设备8和终端设备9在同一小区内相邻。另外，如果将小区82记为第一小区，则小区81或小区83可记为第二小区，在这种情况下，第一终端设备可以是小区82中的终端设备12，终端设备1和终端设备2可分别记为第二终端设备，终端设备13可记为第三终端设备。其中，第一终端设备、第二终端设备、第三终端设备分别对应的上行OAM模态和/或下行OAM模态可参照上述实施例所述的内容，此处不再赘述。
下面以如图10所示的小区81为第一小区，小区82为第二小区，终端设备1为第一终端设备，终端设备12、终端设备13、终端设备14和终端设备15分别为第二终端设备，终端设备2、终端设备8、终端设备9分别为第三终端设备为例进行示意性说明。
当第一终端设备对应的上行OAM模态信息与至少一个第二终端设备对应的上行OAM模态信息不同，第一终端设备对应的下行OAM模态信息与至少一个第二终端设备对 应的下行OAM模态信息不同时，可以将终端设备1、终端设备2、终端设备8、终端设备9分别对应的上行OAM模态信息构成第一集合，将终端设备12、终端设备13、终端设备14和终端设备15分别对应的上行OAM模态信息构成第二集合。或者，将终端设备1、终端设备2、终端设备8、终端设备9分别对应的下行OAM模态信息构成第一集合，将终端设备12、终端设备13、终端设备14和终端设备15分别对应的下行OAM模态信息构成第二集合。
当第一终端设备对应的上行OAM模态信息与至少一个第二终端设备对应的下行OAM模态信息不同，第一终端设备对应的下行OAM模态信息与至少一个第二终端设备对应的上行OAM模态信息不同时，可以将终端设备1、终端设备2、终端设备8、终端设备9分别对应的上行OAM模态信息构成第一集合，将终端设备12、终端设备13、终端设备14和终端设备15分别对应的下行OAM模态信息构成第二集合。或者，将终端设备1、终端设备2、终端设备8、终端设备9分别对应的下行OAM模态信息构成第一集合，将终端设备12、终端设备13、终端设备14和终端设备15分别对应的上行OAM模态信息构成第二集合。
其中，所述第一集合中的OAM模态信息是连续的；或者所述第一集合中的OAM模态信息是离散的；或者所述第一集合中的OAM模态信息是部分连续、部分离散的。同理，所述第二集合中的OAM模态信息是连续的；或者所述第二集合中的OAM模态信息是离散的；或者所述第二集合中的OAM模态信息是部分连续、部分离散的。
下面以第一集合包括上行OAM模态信息、第二集合也包括上行OAM模态信息为例进行示意性说明，其他情况与此类似，不再一一赘述。
在一种可能的实现方式中，第一集合中的OAM模态信息是连续的，第二集合中的OAM模态信息是连续的，例如，终端设备1、终端设备2、终端设备8、终端设备9分别对应的上行OAM模态信息依次为1、2、3、4，第一集合可表示为{1、2、3、4}，或者该第一集合也可以采用OAM模态信息初始值1、OAM模态信息间隔Δl＝1、OAM模态信息个数4来表示。终端设备12、终端设备13、终端设备14和终端设备15分别对应的上行OAM模态信息依次为5、6、7、8，第二集合可表示为{5、6、7、8}，或者该第二集合也可以采用OAM模态信息初始值5、OAM模态信息间隔Δl＝1、OAM模态信息个数4来表示。可见第一集合和第二集合之间是连续的。位于相邻小区公共边界周围的不同终端设备对应的上行OAM模态信息不同，因此，位于相邻小区公共边界周围的不同终端设备采用的OAM波的波前相位旋转是不同的，且该不同终端设备采用的OAM波彼此之间是正交的，从而抑制了相邻小区公共边界周围的不同终端设备之间的信号干扰。另外，第一集合和第二集合之间没有交集，说明第一集合中任一OAM模态信息对应的OAM波和第二集合中任一OAM模态信息对应的OAM波之间是正交的。
在其他实施例中，当第一集合中的OAM模态信息连续，第二集合中的OAM模态信息也连续时，第一集合和第二集合之间可以是离散的，并且第一集合和第二集合之间的间隔大于或等于预设间隔。例如，第一集合为{1、2、3、4}，第二集合为{8、9、10、11}，第一集合和第二集合之间的间隔为OAM模态信息4和OAM模态信息8之间的间隔，若预设间隔为3，则OAM模态信息4和OAM模态信息8之间的间隔大于3。在这种情况下，第一集合和第二集合之间的间隔可以降低相邻小区间属于不同小区且位置相邻的终端设 备分别采用的OAM波之间的能量泄露，进一步降低了相邻小区间属于不同小区且位置相邻的终端设备之间的信号干扰。
在另一种可能的实现方式中，第一集合中的OAM模态信息和第二集合中的OAM模态信息分别是离散的，例如，第一集合表示为{-7、-5、-3、-1}，第二集合表示为{1、3、5、7}。第一集合中相邻OAM模态信息之间的间隔有多个，例如，-7和-5之间有一个OAM模态信息间隔，-5和-3之间有一个OAM模态信息间隔，-3和-1之间有一个OAM模态信息间隔，并且这些间隔都是2。同理，第二集合中相邻OAM模态信息之间的间隔也为2。在一些实施例中，第一集合中相邻OAM模态信息之间的间隔可以和第二集合中相邻OAM模态信息之间的间隔不同，例如，第二集合表示为{1、4、7、10},即第二集合中相邻OAM模态信息之间的间隔为3。
此外，第一集合中的多个OAM模态信息间隔可以不同，例如，第一集合表示为{-5、-4、-2、2}。或者，第一集合中的多个OAM模态信息间隔可以部分相同、部分不同，例如，第一集合表示为{-5、-4、-2、-1}。同理，第二集合中的多个OAM模态间隔信息可以不同，或者第二集合中的多个OAM模态信息间隔可以部分相同、部分不同，此处不再赘述，第一集合中任一OAM模态信息对应的OAM波和第二集合中任一OAM模态信息对应的OAM波正交即可。
在又一种可能的实现方式中，第一集合中的OAM模态信息部分连续、部分离散，第二集合中的OAM模态信息部分连续、部分离散，例如，第一集合可表示为{1、2、3、5}，第二集合可表示为{7、8、9、11}，其中，1、2、3之间是连续的，第一集合的子集{1、2、3}和5之间是离散的。7、8、9之间是连续的，第二集合的子集{7、8、9}和11之间是离散的。
另外，第一集合中还可以存在多个连续的OAM模态信息子集，并且该多个连续的OAM模态信息子集之间是离散的，例如，第一集合可表示为{1、2、5、6}，其中，1、2之间是连续的，5、6之间是连续的，第一集合的子集{1、2}和第一集合的子集{5、6}之间是离散的。同理，第二集合中也可以存在多个连续的OAM模态信息子集，并且该多个连续的OAM模态信息子集之间是离散的，第一集合中任一OAM模态信息对应的OAM波和第二集合中任一OAM模态信息对应的OAM波正交即可。
可以理解的是，第一集合和第二集合可以不同时连续，或者第一集合和第二集合可以不同时离散，或者第一集合和第二集合可以不同时部分连续、部分离散。例如，第一集合中的OAM模态信息连续，第二集合中的OAM模态信息离散。或者第一集合中的OAM模态信息部分连续、部分离散，第二集合中的OAM模态信息连续。第一集合中任一OAM模态信息对应的OAM波和第二集合中任一OAM模态信息对应的OAM波正交即可。
另外，第一集合中还可以存在相互对称的OAM模态信息，例如，第一集合可表示为{-4、-1、1、4}，其中，-4和4是相互对称的OAM模态信息，-1和1是相互对称的OAM模态信息，相互对称的OAM模态信息对应的OAM波的相位正好是相反的，即波前相位正好是方向对称的，如此可以降低实现的复杂度，保证较好的正交性，可进一步降低小区边缘终端设备之间的信号干扰。同理，第二集合中也可以存在相互对称的OAM模态信息，例如，第二集合表示为{-6、-2、2、6}。
此外，如图10所示，小区81中的边缘终端设备，例如，终端设备1、终端设备2、…、 终端设备9对应的上行OAM模态信息的集合可记为第三集合，网络设备84可以从该第三集合中确定终端设备1、终端设备2、…、终端设备9中每个终端设备对应的上行OAM模态信息。该第三集合可以是小区81支持的上行OAM模态信息构成的集合的子集。同理，第二集合也可以是小区82中的边缘终端设备对应的上行OAM模态信息集合的子集。
可以理解的是，如果第一集合包括下行OAM模态信息、第二集合也包括下行OAM模态信息，可以将小区81中的边缘终端设备对应的下行OAM模态信息的集合记为第三集合，该第一集合可以是第三集合的子集，网络设备84可以从第三集合中确定终端设备1到终端设备9中每个终端设备对应的下行OAM模态信息。该第三集合可以是小区81支持的下行OAM模态信息构成的集合的子集。同理，第二集合也可以是小区82中的边缘终端设备对应的下行OAM模态信息集合的子集。
另外，每个小区中的中心终端设备对应的上行OAM模态信息集合可以是该小区支持的上行OAM模态信息集合。每个小区中的中心终端设备对应的下行OAM模态信息集合可以是该小区支持的下行OAM模态信息集合。
需要注意的是，由于OAM模态信息为0的无线电磁波不是OAM波，因此，在本申请实施例中可以将OAM模态信息-1和OAM模态信息1看成是连续的OAM模态信息。OAM模态信息-1和OAM模态信息1之间的OAM模态信息间隔Δl＝1。OAM模态信息-1和OAM模态信息2之间的OAM模态信息间隔Δl＝2。
下面结合图8对小区81、小区82、小区83之间相邻终端设备对应的上行OAM模态信息或下行OAM模态信息进行介绍。如图8所示，小区81中的终端设备1和终端设备2，与小区82中的终端设备12和终端设备13相邻。小区81中的终端设备8和终端设备9，与小区83中的终端设备10和终端设备11相邻。小区82中的终端设备15和终端设备16，与小区83中的终端设备17和终端设备18相邻。终端设备1、终端设备2、终端设备8、终端设备9分别对应的上行OAM模态信息或下行OAM模态信息构成集合lA，终端设备12、终端设备13、终端设备15和终端设备16分别对应的上行OAM模态信息或下行OAM模态信息构成集合lB，终端设备10、终端设备11、终端设备17和终端设备18分别对应的上行OAM模态信息或下行OAM模态信息构成集合lC。
在一种可能的实现方式中，lA、lB、lC各自包括的OAM模态信息是连续的。例如，lA＝{-4、-3、-2、-1}，lB＝{1、2、3}，lC＝{4、5、6、7、8}，并且lA、lB、lC相互之间是正交的，从而可以降低小区81、小区82、小区83之间的相互干扰。具体的，lA、lB、lC之间是连续的。例如，lA和lB是连续的，lB和lC是连续的。另外，lA还可以采用OAM模态信息初始值-4、OAM模态信息间隔Δl＝1、OAM模态信息个数4来表示。lB还可以采用OAM模态信息初始值1、OAM模态信息间隔Δl＝1、OAM模态信息个数4来表示。lC还可以采用OAM模态信息初始值4、OAM模态信息间隔Δl＝1、OAM模态信息个数4来表示。
在其他实施例中，lA、lB、lC之间还可以是离散的，例如，lA＝{-4、-3、-2、-1}，lB＝{2、3}，lC＝{6、7、8}，其中，lA和lB之间的OAM模态信息间隔Δl＝2。lB和lC之间的OAM模态信息间隔Δl＝3。lA、lB、lC之间的间隔可以降低相邻小区间属于不同小区且位置相邻的终端设备分别采用的OAM波之间的能量泄露，进一步降低了相邻小区间属于不同小区且位置相邻的终端设备之间的信号干扰。
在另一种可能的实现方式中，lA、lB、lC各自包括的OAM模态信息是离散的。例如，lA＝{-4、-1、3、6}，lB＝{-3、1、4、7}，lC＝{-2、2、5、8}，并且lA、lB、lC相互之间是正交的，从而可以降低小区81、小区82、小区83之间的相互干扰。另外，lA还可以采用OAM模态信息初始值-4、OAM模态信息间隔Δl＝3、OAM模态信息个数4来表示。lB还可以采用OAM模态信息初始值-3、OAM模态信息间隔Δl＝3、OAM模态信息个数4来表示。lC还可以采用OAM模态信息初始值-2、OAM模态信息间隔Δl＝3、OAM模态信息个数4来表示。
在其他实施例中，lA、lB、lC各自对应的OAM模态信息间隔可以是不同的，例如，lA＝{-4、-1、1、4}，lB＝{-5、2、2、5}，lC＝{-6、-3、3、6}，其中，lA对应的OAM模态信息间隔包括Δl＝1及Δl＝3。lB对应的OAM模态信息间隔包括Δl＝3。lC对应的OAM模态信息间隔包括Δl＝3及Δl＝5。其中，lA、lB、lC分别包括相互对称的OAM模态信息，例如，lA包括的-4和4是相互对称的OAM模态信息，-1和1是相互对称的OAM模态信息，相互对称的OAM模态信息对应的OAM波的相位正好是相反的，即波前相位正好是方向对称的，如此可以降低实现的复杂度，保证较好的正交性，可进一步降低小区边缘终端设备之间的信号干扰。
在另一种可能的实现方式中，lA、lB、lC各自包括的OAM模态信息是部分连续、部分离散的。例如，lA＝{-4、-3、-2、4}，其中，-4、-3、-2是连续的，子集{-4、-3、-2}与4之间是离散的。lB＝{1、2、3、8}，其中，1、2、3是连续的，子集{1、2、3}与8之间是离散的。lC＝{-1、5、6、7}，其中，5、6、7是连续的，子集{5、6、7}与-1之间是离散的。
另外，lA、lB、lC各自内部还可以包括多个连续的OAM模态信息子集，并且该多个连续的OAM模态信息子集之间是离散的，例如，lA＝{{2、-1、1、2}，其中，-2、-1是连续的，1、2是连续的，子集{-2、-1}和子集{1、2}之间是离散的。lB＝{-6、-5、5、6}，其中，-6、-5是连续的，5、6是连续的，子集{-6、-5}和子集{5、6}之间是离散的。lC＝{-10、-9、9、10}，其中，-10、-9是连续的，9、10是连续的，子集{-10、-9}和子集{9、10}之间是离散的。另外，lA中任一OAM模态信息和lB中任一OAM模态信息之间的间隔大于或等于预设间隔3，lB中任一OAM模态信息和lC中任一OAM模态信息之间的间隔大于或等于预设间隔3，lA中任一OAM模态信息和lC中任一OAM模态信息之间的间隔大于或等于预设间隔3，从而可降低相邻小区间属于不同小区且位置相邻的终端设备分别采用的OAM波之间的能量泄露，进一步降低了相邻小区间属于不同小区且位置相邻的终端设备之间的信号干扰。
可以理解的是，如上所述的集合中的OAM模态信息的具体数值只是示意性说明，并不作具体限定。
可以理解的是，上述实施例中的部分或全部步骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照上述实施例呈现的不同的顺序来执行，并且有可能并非要执行上述实施例中的全部操作。
可以理解的是，以上各个实施例中，由终端设备实现的操作或者步骤，也可以由可用于终端设备的部件(例如芯片或者电路)实现，由网络设备实现的操作或者步骤，也可以由可用于网络设备的部件(例如芯片或者电路)实现。
