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作出创造 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。
需要指出的見 本发明上述的各个实施例不仅可以适用于 FDD ( Frequency Division Duplexing , 频分双工) 系统, 也可以适用于 TDD ( Time Division Duplexing , 时分双工) 系统, 以及其他系统, 例如 FDD和 TDD的混合系统。 实施例 1
本发明实施例提供一种通信信号传输方法, 该方法为多频接收机侧的方法, 如图 3所示, 该方法包括:
101、 多频接收机从天线接收射频信号, 并按照频段将所述射频信号分为不 同频段的射频信号。
其中, 所述多频接收机从天线接收射频信号, 并按照频段将所述射频信号 分为不同频段的射频信号, 具体的, 如图 4 所示, 当多频接收机从天线接收射 频信号, 该射频信号包括 3 个频段的射频信号时, 按照频段将所述多频接收机 从天线接收的射频信号分为三个频段的射频信号, 具体为 F1频段的射频信号、 F2频段的射频信号、 以及 F 3频段的射频信号。 并且, 每个频段对应多路接收该 频段射频信号的接收通路, 例如, F1频段的射频信号由 4路接收通路接收, 具 体为图 4 中的 4个 FIR ; F2频段的射频信号由 4路接收通路接收, 具体为图 4 中的 4个 F2R, F3频段的射频信号由 4路接收通路接收, 具体为图 4中的 4个 F31R。
102、 所述多频接收机将预定频段第一部分的射频信号发送给射频单元, 以 便所述射频单元将接收到的射频信号转换为第一基带数字信号发送给基带处理 单元; 以及将所述预定频段第二部分的射频信号转换为第二基带数字信号, 并 将所述第二基带数字信号发送给基带处理单元。 其中, 所述将预定频段第一部分的射频信号发送给射频单元, 以便所述射 频单元将接收到的射频信号转换为第一基带数字信号发送给基带处理单元, 包 括: 将第一频段一部分的射频信号发送给第一射频模块, 以便所述第一射频模 块将接收到的射频信号转换为第一基带数字信号发送给基带处理单元。
其中, 需要说明的是, 该处的第一频段泛指多频接收机所包含的任一频段, 并不局限据第一个频段; 例如, 如图 4所示, 将该第一频段预设置为 F1频段, 所述将第一频段一部分的射频信号发送给第一射频模块, 以便所述第一射频模 块将接收到的射频信号转换为第一基带数字信号发送给基带处理单元, 可以为 将 F1频段的两个接收通路(接收通路①和接收通路②)接收的射频信号发送给 第一射频模块, 以便所述第一射频模块将接收到的两路射频信号分别转换为各 自对应的第一基带数字信号, 并将所述第一基带数字信号发送给基带处理单元。
所述将所述预定频段第二部分的射频信号转换为第二基带数字信号, 并将 所述第二基带数字信号发送给基带处理单元包括: 将第一频段剩余部分的射频 信号转换为第二基带数字信号, 并将所述第二基带数字信号发送给基带处理单 元。
例如, 如图 4所示, 将 F1频段剩余部分的射频信号转换为第二基带数字信 号, 并将所述第二基带数字信号发送给基带处理单元, 可以为将 F1频段的剩余 两个接收通路(接收通路③和接收通路④)接收的射频信号, 分别转换为各自 对应的第二基带数字信号, 并通过数字基带接口将所述第二基带数字信号发送 给基带处理单元。 其中图 4中所示的 P霊表示电源的接口。
不难理解, 图 4描述的是 FDD系统下多频接收机接收射频信号的流程示意 图。 而图 20则描述了 TDD 系统下多频接收机接收射频信号的流程。 其中图 20 与图 4的区别在于, 图 4一个接收机中同一个频段的接收通路和发射通路对应 不同的物理通路, 而图 20—个接收机中同一个频段的接收通路和发射通路对应 同一个物理通路。
本发明实施例还提供一种通信信号传输方法, 该方法为基带处理单元侧的 方法, 如图 5所示, 该方法包括:
201、 基带处理单元接收多频接收机发送的预定频段的第二基带数字信号和 射频单元发送的该预定频段的第一基带数字信号。
其中, 所述第二基带数字信号由多频接收机接收到的预定频段的射频信号 中的第二部分射频信号转换得到; 所述第一基带数字信号由射频单元将多频接 收机接收到的预定频段的射频信号中的第一部分射频信号转换得到。
例如, 对应于图 4的相应描述, 还是以 F1频段为例进行说明, 本发明实施 例中的所述第二基带数字信号为多频接收机接收到的 F1频段的射频信号中的接 收通路③和接收通路④接收射频信号转换得到, 包含两路的接收; 所述第一基 带数字信号由射频单元将多频接收机接收到的 F1频段的射频信号中的接收通路 ①和接收通路②接收射频信号转换得到, 也包含两路的接收; 因此, 将该基带 处理单元, 接收到所述第一基带数字信号和所述第二基带数字信号时, 便对一 个频段有了 4路的接收。
需要说明的是, 当多频接收机将多个频段的接收的射频信号各自进行上述 操作时, 所述基带处理单元便可对多个频段都有多路的接收了。
202、 对所述第一基带数字信号和第二基带数字信号进行基带处理。
其中, 对所述第一基带数字信号和第二基带数字信号进行基带处理, 具体 处理过程可以采用现有技术中的任一方法, 本发明实施例对此不进行限制。
本发明实施例中, 多频接收机将从天线接收到的射频信号进行分频段, 得 到不同频段的射频信号, 并将预定频段中的第一部分射频信号发送给射频单元, 以便该射频单元将其接收到的所述预定频段中的第一部分射频信号转化为第一 基带数字信号发送给基带处理单元, 以及将该预定频段中的第二部分射频信号 转化为第二基带数字信号, 并将所述第二基带数字信号发送给该基带处理单元; 使得该基带处理单元可以接收到不同频段各自对应的多路接收信号, 从而在不 增加天线的基础上, 增加了网络系统接收不同频段各自对应的射频信号的路数, 从而增强了网络系统的接收性能; 并且本发明实施例提供的技术方案, 仅通过 多频接收机数字基带接口将预定频段第二部分射频信号对应的基带数字信号发 送给基带处理单元, 使其以一种简单的方式实现多接收。
上面的实施例结合图 4 对通信信号传输方法进行了具体描述, 显然, 该方 法也适用于图 20 , 其具体处理过程和图 4基本一致, 此处不再详述。 实施例 2

302、 所述多频接收机将预定频段第一部分的射频信号发送给射频单元, 以 便所述射频单元将接收到的射频信号转换为第一基带数字信号发送给基带处理 单元; 以及将所述预定频段第二部分的射频信号转换为第二基带数字信号后发 送给所述射频单元, 以便所述射频单元将所述第二基带数字信号发送给所述基 带处理单元。

所述将所述预定频段第二部分的射频信号转换为第二基带数字信号后发送 给所述射频单元, 以便所述射频单元将所述第二基带数字信号发送给所述基带 处理单元, 包括; 将第一频段剩余部分的射频信号转换为第二基带数字信号, 并将所述第二基带数字信号发送给所述第一射频模块, 以便所述第一射频模块 将所述第二基带数字信号发送给所述基带处理单元。 其中, 将所述预定频段第 二部分的射频信号转换为第二基带数字信号, 并发送给所述射频单元, 以便所 述射频单元将所述第二基带数字信号发送给所述基带处理单元的具体描述, 可 以参考实施例 1 中步骤 102 的相应描述, 不同的是, 将第二基带数字信号后发 送给所述射频单元, 再由所述射频单元将第二基带数字信号转发给所述基带处 理单元。
本发明实施例还提供一种通信信号传输方法, 该方法为基带处理单元侧的 方法, 如图 7所示, 该方法包括:

其中, 所述第二基带数字信号由多频接收机接收到的预定频段的射频信号 中的第二部分射频信号转换得到, 并由所述多频接收机将所述第二基带数字信 号发送给所述射频单元, 以便所述射频单元将所述第二基带数字信号发送给基 带处理单元; 所述第一基带数字信号由射频单元将多频接收机接收到的预定频 段的射频信号中的第一部分射频信号转换得到。
