Description

一种时隙复用方法、装置及通信设备 技术领域
本发明涉及通信技术领域，特别是涉及一种时隙复用方法、装置及通信设备。
背景技术
在时分多址通信系统中，无线网格Mesh网络的物理层帧的帧长为20ms，前10ms为静态分配，为各节点分配固定的时隙；后10ms为动态分配，可以根据业务需要调整分配给各节点的时隙。图3对静态分配进行了举例说明，如图3所示，RF0为静态分配资源，也即物理层帧的前10ms，将静态分配资源分为九个时隙，分别为T0至T9，将T0至T9依次分配给节点N0至N9，如虚线所示。每个节点只在分配给该节点的时隙内进行数据发送，在其他时隙内则不进行数据发送。
图4对动态分配进行了举例说明，如图4所示，RF1为动态分配资源，也即物理层帧的后10ms，将动态分配资源分为九个时隙，分别为T10至T19，将T10至T12分配给节点N0，将T13至T15分配给节点N3，将T16分配给节点N6，将T17至T19分配给节点N7，如虚线所示。每个节点只在分配给该节点的时隙内进行数据发送，在其他时隙内则不进行数据发送。
可见，无论是静态分配还是动态分配，现有的时分多址通信系统中，每个时隙下仅有一个节点可以进行数据发送，这大大降低了节点的资源利用率和频谱效率。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1所示，本发明实施例提供的一种时隙复用方法，应用于时分多址通信系统，该方法可以包括：
S100、根据所述时分多址通信系统的子网中各节点的连接关系确定所述子网中的至少一个复用节点组，任意一个所述复用节点组中的任意两个节点之间的最短通信链路中至少包括包含所述两个节点在内的预设数目的节点，所述预设数目不小于4；
其中，所述时分多址通信系统可以为长期演进LTE系统，所述子网可以为MESH网络的子网，MESH网络的中文名称为无线网格网络。
MESH网络是一种自组织网络，它具有多跳、转发、自愈等特点。
步骤S100根据所述时分多址通信系统的子网中各节点的连接关系确定所述子网中的至少一个复用节点组，可以具体包括：
根据所述LTE系统的无线网格网络的子网中各节点的连接关系确定所述 子网中的至少一个复用节点组。
为了确定网络区域，分开网络区域中节点的接口，产生了多个分离的网络岛，这些分离的网络岛叫做子网。一般不同子网之间的距离比较远，因此不同子网内的节点可以直接进行时隙复用。当然，网络中的所有节点都可以采用本发明的方法进行时隙复用。
其中，各节点的连接关系可以从路由关系表和邻居关系表中获得。
其中，所述预设数目可以为6个。
当两个节点相邻时，这两个节点之间的最短通信链路仅由这两个节点构成，这两个节点直接通信。随着预设数目的增大，这两个节点之间的距离也越来越大。如图2所示，以蜂窝网络为例进行说明，每个基站作为一个节点，设第一节点为节点01，第二节点为节点23。第一节点和第二节点之间的最短通信链路由六个节点构成，如：节点01-节点05-节点08-节点14-节点20-节点23；或，节点01-节点02-节点08-节点10-节点16-节点23。
节点之间的距离越远，节点的空间隔离就越大，当距离足够远时，就不会引起同频干扰，因此可以时隙复用。图2中仅示出了子网中的部分节点，可以理解的是，子网中可以包括更多的节点，这样，距离较远的节点数量就较多，复用同一时隙的节点数量可以更多。
具体的，根据所述时分多址通信系统的子网中各节点的连接关系确定所述子网中的至少一个复用节点组，包括：
对任意两个节点：根据所述时分多址通信系统的子网中各节点的连接关系判断该两个节点是否相邻，如果不相邻，则判断该两个节点的相邻节点的相邻节点中是否有重复的节点，如果无重复的节点，则将该两个节点放入一复用节点组中。
两个节点不相邻且两个节点的相邻节点的相邻节点中无重复的节点，也说明两个节点的距离较远，可以时隙复用。如图2所示，节点01与节点23不相邻。节点01的相邻节点为节点02、03和05，节点01的相邻节点的相邻节点为：节点04、节点08、节点11、节点09和节点06。节点23的相邻节点为节点19、节点16、节点20、节点26、节点28和节点25；节点23的相邻节点的相邻节点为：节点13、 节点10、节点11、节点14、节点17、节点24、节点29、节点31、节点32、节点30、节点27和节点22。可见，节点01的相邻节点的相邻节点与节点23的相邻节点的相邻节点中无重复的节点，节点01与节点23可时隙复用。
S200、对每个复用节点组：确定分配给该复用节点组的复用时隙，控制该复用节点组中的各节点在所述复用时隙下进行数据发送，其中，该复用节点组中各节点均可在所述复用时隙下的任意时刻进行数据发送。
具体的，所述确定分配给该复用节点组的复用时隙，可以包括：
确定分别分配给该复用节点组中各节点的时隙，将确定的各时隙组成复用时隙。
现有的时隙分配方案是为每一个节点分配相应的时隙，因此本发明可以在现有的时隙分配方案基础上实施：首先为每一个节点分配相应的时隙，然后将分配给位于同一复用节点组中的各节点的时隙组成与该复用节点组对应的复用时隙，控制该复用节点组中的各节点在对应的复用时隙下进行数据发送。
例如：复用节点组中包括第一节点、第二节点和第三节点，为第一节点、第二节点和第三节点分配的时隙分别为：第一时隙、第二时隙和第三时隙，则复用时隙由这三个时隙构成，上述三个节点都可以在这三个时隙内进行数据发送。具体的：第一节点可以在第一时隙、第二时隙和第三时隙中的任意个时隙内进行数据发送，同样，第二节点和第三节点也可以在第一时隙、第二时隙和第三时隙中的任意个时隙内进行数据发送。
具体的，在本发明的方案应用到静态分配上时，复用节点组中的节点可以复用为该复用节点组中各节点分配的时隙，例如：如图5所示，节点N0和节点N4位于同一复用节点组中，则与图3相比，节点N0不仅可以T0内发送数据，还可以在T4内发送数据，同样的，节点N4不仅可以在T4内发送数据，还可以在T0内发送数据。
具体的，在本发明的方案应用到动态分配上时，复用节点组中的节点可以复用为该复用节点组中各节点分配的时隙，例如：如图6所示，节点N3和节点N6位于同一复用节点组中，则与图4相比，节点N3不仅可以在T13至T15内发送数据，还可以在T16内发送数据，同样的，节点N6不仅可以在T16内发送数 据，还可以在T13至T15内发送数据，例如：节点N3在T13、T14和T15内发送数据，节点N6在T14、T15和T16内发送数据。
本发明实施例提供的时隙复用方法，可以根据各节点的连接关系确定子网中的至少一个复用节点组，任意一个所述复用节点组中的任意两个节点之间的最短通信链路中至少包括包含所述两个节点在内的预设数目的节点，所述预设数目不小于4；对每个复用节点组：确定分配给该复用节点组的复用时隙，控制该复用节点组中的各节点在所述复用时隙下进行数据发送。由于复用节点组中的节点可以对时隙进行复用，因此在可复用的时隙内，多个节点都可以在该时隙内进行数据发送，大大提高了节点的资源利用率和频谱效率。同时，由于本发明控制了进行时隙复用的节点之间最短通信链路中节点数目，使得只有当两个节点之间通信路径的距离较远时才能对时隙进行复用，避免了复用同一时隙的节点间的信号干扰，保证了通信效果。
与上述方法实施例相对应，本发明还提供了一种时隙复用装置。
如图7所示，本发明实施例提供的一种时隙复用装置，应用于时分多址通信系统，该装置可以包括：复用节点确定单元100和时隙分配单元200，
所述复用节点确定单元100，用于根据所述时分多址通信系统的子网中各节点的连接关系确定所述子网中的至少一个复用节点组，任意一个所述复用节点组中的任意两个节点之间的最短通信链路中至少包括包含所述两个节点在内的预设数目的节点，所述预设数目不小于4；
其中，所述时分多址通信系统可以为长期演进LTE系统，所述子网可以为MESH网络的子网，MESH网络的中文名称为无线网格网络。
MESH网络是一种自组织网络，它具有多跳、转发、自愈等特点。
复用节点确定单元100可以根据所述LTE系统的无线网格网络的子网中各节点的连接关系确定所述子网中的至少一个复用节点组。
其中，所述预设数目可以为6个。
为了确定网络区域，分开网络区域中节点的接口，产生了多个分离的网络岛，这些分离的网络岛叫做子网。一般不同子网之间的距离比较远，因此不同 子网内的节点可以直接进行时隙复用。当然，网络中的所有节点都可以采用本发明的方法进行时隙复用。
其中，各节点的连接关系可以从路由关系表和邻居关系表中获得。
其中，所述复用节点确定单元100，可以包括：第一节点判断单元和第二节点判断单元，
所述第一节点判断单元，用于对任意两个节点：根据所述连接关系判断该两个节点是否相邻，如果不相邻，则触发所述第二节点判断单元；
所述第二节点判断单元，用于判断该两个节点的相邻节点的相邻节点中是否有重复的节点，如果无重复的节点，则将该两个节点放入一复用节点组中，任意一个所述复用节点组中的任意两个节点之间的最短通信链路中至少包括包含所述两个节点在内的预设数目的节点。
当两个节点相邻时，这两个节点之间的最短通信链路仅由这两个节点构成，这两个节点直接通信。随着预设数目的增大，这两个节点之间的距离也越来越大。节点之间的距离越远，节点的空间隔离就越大，当距离足够远时，就不会引起同频干扰，因此可以时隙复用。
所述时隙分配单元200，可以用于对每个复用节点组：确定分配给该复用节点组的复用时隙，控制该复用节点组中的各节点在所述复用时隙下进行数据发送，其中，该复用节点组中各节点均可在所述复用时隙下的任意时刻进行数据发送。

对每个复用节点组：确定分别分配给该复用节点组中各节点的时隙，将确定的各时隙组成复用时隙，控制该复用节点组中的各节点在所述复用时隙下进行数据发送，其中，该复用节点组中各节点均可在所述复用时隙下的任意时刻进行数据发送。
现有的时隙分配方案是为每一个节点分配相应的时隙，因此本发明可以在现有的时隙分配方案基础上实施：首先为每一个节点分配相应的时隙，然后将分配给位于同一复用节点组中的各节点的时隙组成与该复用节点组对应的复 用时隙，控制该复用节点组中的各节点在对应的复用时隙下进行数据发送。
本发明实施例提供的时隙复用装置，可以根据各节点的连接关系确定子网中的至少一个复用节点组，任意一个所述复用节点组中的任意两个节点之间的最短通信链路中至少包括包含所述两个节点在内的预设数目的节点，所述预设数目不小于4；对每个复用节点组：确定分配给该复用节点组的复用时隙，控制该复用节点组中的各节点在所述复用时隙下进行数据发送。由于复用节点组中的节点可以对时隙进行复用，因此在可复用的时隙内，多个节点都可以在该时隙内进行数据发送，大大提高了节点的资源利用率和频谱效率。同时，由于本发明控制了进行时隙复用的节点之间最短通信链路中节点数目，使得只有当两个节点之间通信路径的距离较远时才能对时隙进行复用，避免了复用同一时隙的节点间的信号干扰，保证了通信效果。
与上述方法及装置实施例相对应，本发明实施例还提供了一种通信设备。

具体的，所述处理器001可以对任意两个节点：根据所述时分多址通信系统的子网中各节点的连接关系判断该两个节点是否相邻，如果不相邻，则判断该两个节点的相邻节点的相邻节点中是否有重复的节点，如果无重复的节点，则将该两个节点放入一复用节点组中。
