E波段微波（ E-band )主要应用于移动基站回传， 基站在城镇的分布非常 广泛， 而且会随着地形和城市布局的不同而变化， 因此可以通过 E-band微波 组成网状网络来连接这些基站。 如图 1所示， 在网状网络的基站小区 1 中分 布有微波节点 2， 微波节点 2之间建立有 E-band微波链路。 其中为实现距离 较远的两个微波节点 2之间的链路， 可在这两个微波节点之间设置一些中间 微波节点， 中间微波节点往往需要连接来自多个方向的链路， 这就需要多个 方向的天线。
如图 2所示， 一种支持 8个方向的多向天线， 根据业务调度的需要， 由 该多向天线组成的中间微波节点实现微波信号的中继， 以进行业务的调度。 例如通过天线 1 接收一个方向上的微波信号， 并将该微波信号传送给另一个 方向上的天线 4， 再由天线 4发射出去。
如图 3 所示， 现有的一种实现微波中继的结构， 通过电缆连接多向天线 中的天线 1和天线 4， 以及天线 2和天线 5。 一个方向上的天线 1接收微波信 号， 经放大和变频后传送给另一个方向上的天线 4， 再由天线 4发射出去。 其 中由于天线 1和天线 5之间没有物理上的电缆连接， 因此天线 1接收的信号 就无法从天线 5 的方向上发射。 这种各方向的天线之间通过固定连线连接的 方式， 不能根据业务需要对该多向天线接收的信号业务进行自由调度。 如图 4所示， 现有的另一种实现微波中继的结构， 多向天线连接有室内单 元（ Indoor Unit, IDU )设备 4， IDU设备 4能够将一个方向上的天线（如天线 2 ) 接收到的微波信号， 通过其它方向上的天线（如天线 7 )发射出去， 以实现业 务的调度。 其业务调度的过程是： 首先把微波射频信号转换为中频信号， 然 后再把中频信号解调得到业务数据流， 最后在业务层面进行调度。 由于不能 直接在中频信号层面进行调度， 这样就增加了成本。
在实现上述使用的过程中， 发明人发现现有技术中至少存在如下问题： 现有的微波中继方法和装置难以在低成本的情况下对信号进行自由调 度。 发明内容

本发明旨在提供一种微波中继接收和发送方法、 装置以及微波中继节点， 能够在低成本情况下对微波信号进行自由调度。 下面结合附图对本发明进行 详细描述。
应当明确， 所描述的实施例仅仅是本发明的一部分实施例， 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， 都属于本发明所保护的范围。
如图 5所示， 本发明实施例提供的微波中继接收方法， 包括：
步骤 501， 接收微波信号， 所述微波信号包括业务信息和控制信息； 其中可以通过接收单元接收该微波信号， 而且接收到的微波信号位于射 频频段。 例如， 对于多向天线而言， 该接收单元可以是该多向天线中一个方 向上的天线装置中的天线。
步骤 502， 分离所述微波信号，得到位于中频频段的业务信息和位于低频 频段的控制信息， 并将分离后的业务信息给开关矩阵； 所述开关矩阵连接在 所述微波信号的中继接收装置和中继发送装置之间， 用于对所述微波信号中 的业务信息进行调度分配；
其中， 可以通过分离单元对该微波信号进行分离， 具体而言， 由于所述 业务信息处于中频频段， 而所述控制信息处于低频频段， 因此可以利用高通 滤波器和低通滤波器对微波信号进行滤波， 以分别得到所述业务信息和所述 控制信息， 此时该分离单元具体可以包括高通滤波器、 低通滤波器等元器件。
这样， 分离所述微波信号就具体为： 首先， 对上述接收到的微波信号进 行下变频， 从而得到位于中频频段的微波信号。 然后， 对其中一部分位于中 频频段的微波信号进行高通滤波， 以得到位于中频频段的业务信息， 并将该 信息发送给开关矩阵； 对另一部分位于中频频段的微波信号进行低通滤波和 模数解调， 以得到位于低频频段的控制信息。
另外需要说明的是， 本实施例中所述的开关矩阵由能够通过中频信号的 开关器件组成， 并可根据中频信号的带宽范围进行选择， 这样所述开关矩阵 即有能力传输位于中频频段的业务信息。
步骤 503， 向所述开关矩阵传输所述控制信息， 以使所述开关矩阵中的相 应开关导通， 并通过该导通的开关传输所述业务信息。

因此， 向所述开关矩阵传输所述控制信息， 以使所述开关矩阵中的相应 开关导通具体为： 首先根据预先存储的控制协议将步骤 502 中得到的控制信 息转换为控制信号， 然后向所述开关矩阵传输所述控制信号， 所述控制信号 则用于控制导通所述开关矩阵中的相应开关。 具体而言， 所述控制信号可以 为一系列高低电平信号， 所述开关矩阵中某个开关所对应的控制信号为高电 平时， 该开关导通。 反之， 所述开关矩阵中某个开关所对应的控制信号为低 电平时， 该开关截止。
而且， 所述控制协议中包含有所述微波信号传输的路由信息， 上述控制 信号控制导通开关矩阵中的与该路由信息相对应的开关。 因此根据该路由信 息即可得知应该导通所述开关矩阵中的哪一个开关， 从而生成相应的控制信 号以控制该开关的导通。
本发明实施例提供的微波中继接收方法， 能够从微波信号中分离出位于 中频频段的业务信息和位于低频频段的控制信息， 并能够根据该控制信息导 通所述开关矩阵中的相应开关以传输该业务信息， 因此可以在中频信号层面 自由进行业务调度， 降低了成本， 所以说能够在低成本情况下对微波信号进 行自由调度。
如图 6所示， 本发明实施例提供的微波中继发送方法， 包括：
步骤 601， 生成位于低频频段的控制信息， 所述控制信息用于控制开关矩 阵中的开关导通， 所述开关矩阵连接在所述微波信号的接收装置和发送装置 之间， 用于对所述微波信号中的业务信息进行调度分配；
其中， 可以通过控制信息生成单元来生成位于低频频段的控制信息， 具 体而言， 该控制信息生成单元可以包括控制器， 以用于生成控制信号； 还可 以包括调制解调器， 以用于将该控制信号调制到低频载波上， 从而生成控制 信息。 因此， 生成位于低频频段的控制信息具体为： 根据预先存储的控制协议， 将用于控制开关矩阵中的开关导通的控制信号调制到低频载波上， 以生成位 于低频频段的控制信息。
其中， 所述低频载波的频率可以为 KHZ级别， 且所述低频载波可以为正 弦波或方波。
步骤 602， 混合位于低频频段的控制信息和位于中频频段的业务信息， 形 成微波信号；

因此， 混合位于低频频段的控制信息和位于中频频段的业务信息具体为： 对位于低频频段的控制信息和位于中频频段的业务信息进行上变频， 以进行 混频调制， 从而得到位于射频频段的微波信号。 其中， 位于低频频段的控制 信息来自于步骤 601 中得到的控制信息， 而位于中频频段的业务信息则来自 于上述实施例的步骤 503中通过所述开关矩阵传输的业务信息。

如图 9所示， 本发明实施例还提供了一种微波中继节点， 包括微波中继 接收装置 7、 开关矩阵 9和微波中继发送装置 8， 开关矩阵 9连接在微波中继 接收装置 7和微波中继发送装置 8之间， 其中：
微波中继接收装置 7， 用于接收微波信号， 所述微波信号包括业务信息和 第一控制信息； 分离所述微波信号， 得到位于中频频段的业务信息和位于低 频频段的第一控制信息， 将分离后的业务信息发送给开关矩阵 9; 向开关矩阵 9传输所述第一控制信息， 以使开关矩阵 9中的相应开关导通；

其中， 开关矩阵由能够通过中频信号的开关器件组成， 并可根据中频信 号的带宽范围进行选择， 这样所述开关矩阵即有能力传输位于中频频段的业 务信息。 例如该开关器件可以选择 ON Semiconductor公司 （安森美半导体公 司 ) 的 NC6433系列器件。
本发明实施例提供的微波中继节点， 能够通过微波中继接收装置 7从微 波信号中分离出位于中频频段的业务信息和位于低频频段的控制信息， 并能 够才艮据该控制信息导通开关矩阵 9 中的相应开关以传输该业务信息， 而且可 以通过微波中继发送装置 8将位于中频频段的业务信息和位于低频频段的控 制信息混合成微波信号后一起发送， 从而使得可以在中频信号层面自由进行 业务调度， 降低了成本， 所以说能够在低成本情况下对微波信号进行自由调 度。
其中， 该微波中继节点包括至少一个多方向天线， 上述微波中继接收装 置 7为该多方向天线中一个方向上的天线装置， 上述微波中继发送装置 8为 该多方向天线中另一个方向上的天线装置。 该微波中继节点通过微波中继接 受装置 7接收上一个微波节点发送的微波信号， 并将该微波信号中的业务信 息通过开关矩阵 9传送给微波中继发送装置 8，从而通过该微波中继发送装置 8将该微波信号发送给下一个微波节点，最终实现了该微波中继节点的业务调 度功能。
如图 10所示， 下面结合具体的实施例说明所述微波中继节点的结构。 图 10中， 该微波中继节点包括一个支持 8个方向的多方向天线， 该多方 向天线具有位于一个方向上的天线 1， 和位于另一个方向上的天线 4， 但并不 局限于此， 也可以具有位于其他方向上的天线 2、 天线 3等。 该微波中继节点 通过天线 1接收上一个微波节点的微波信号， 并将该微波信号传送给天线 4， 并通过天线 4 向下一个微波节点发送该微波信号。 其中， 该上一个微波节点 可以是微波中继节点、 也可以是微波源节点； 该下一个微波节点可以是微波 中继节点、 也可以是 波目标节点。
如图 10中实线所示，首先天线 1接收到上一个微波节点发送的微波信号， 并通过双工器 1001将该微波信号传送给 LNA ( Low Noise Amplifier, 低噪声 放大器） 1002， LNA1002对该微波信号进行放大后输出给下变频器 1003， 下 变频器 1003对该微波信号进行下变频， 以得到位于中频频段的信号， 并将该 位于中频频段的信号分两路输出， 一路输出给高通滤波器 1004， 另一路输出 给低通滤波器 1005。
其中高通滤波器 1004对该位于中频频段的信号进行高通滤波， 以得到位 于中频频段的业务信息，并将该业务信息输出给开关矩阵；而低通滤波器 1005 则对该位于中频频段的信号进行低通滤波， 以得到位于低频频段的第一控制 信息， 并将该第一控制信息输出给 A/D解调器（模数解调器） 1006， 从而将 该第一控制信息由模拟信号模式转换为数字信号模式。
然后将该具有数字信号模式的第一控制信息送入到控制器 1007中， 控制 器 1007根据预先存储在其中的控制协议将该第一控制信息转换为控制信号， 并利用该控制信号导通所述开关矩阵中的开关。 其中具体而言， 该控制协议 中包含有所述微波信号传输的路由信息， 根据该路由信息即可得知应该导通 所述开关矩阵中的哪一个开关； 该控制信号可以为一系列高、 低电平信号， 所述开关矩阵中某个开关所对应的控制信号为高电平时， 该开关导通。 反之， 所述开关矩阵中某个开关所对应的控制信号为低电平时， 该开关截止。
例如， 如图 11所示， 如果才艮据上述路由信息得知应该导通开关矩阵中与 天线 4相应的开关， 则此时控制信号中与天线 4相对应的电平为高， 而与其 余天线相对应的电平为低时， 因此与天线 4相对应的开关导通， 而与其余天 线相对应的开关截止， 此时， 天线 1接收到的业务信息就可以通过该开关矩 阵传送给天线 4， 然后再由天线 4向下一个微波节点发送，从而实现业务的调 度。
其中， 由天线 4 向下一个微波节点发送业务信息的具体实现为， 首先控 制器 1007根据预先存储在其中的控制协议， 生成用于控制下一个微波节点的 开关矩阵中的开关导通的控制信号， D/A调制器（数模调制器） 1008将该控 制信号调制到低频载波上， 以生成位于低频频段的第二控制信息， 并将该第 二控制信息输出给上变频器 1009。 其中该低频载波的频率可以为 KHZ级别， 且所述低频载波可以为正弦波或方波。
上变频器 1009对位于低频频段的第二控制信息和位于中频频段的业务信 息上变频， 以进行混频调制， 从而得到位于射频频段的微波信号。 然后将该 微波信号依次输出给前放器 1010和功放器 1011， 前放器 1010和功放器 1011 对该微波信号进行放大后， 输出给双工器 1001， 并由该双工器 1001输出给天 线 4， 最后由天线 4将该微波信号发送出去。
此处需要说明的是， 本实施例还可以在 LNA1002处进行业务信息和控制 信息的分离。 另外本实施例中， 还可以在前放器 1010或功放器 1011处进行 信号的调制。
其中：
前述的接收单元 701具体可以为天线 1 ;
前述的分离单元 702具体可以包括 LNA1002、 下变频器 1003、 高通滤波 器 1004、 低通滤波器 1005、 以及 A/D解调器 1006;
前述的控制单元 703具体可以为控制器 1007;
前述的控制信息生成单元 801具体可以包括控制器 1007和 D/A调制器 1008;
前述的混合单元 802具体可以包括上变频器 1009、 前放器 1010、 以及功 放器 1011 ;
前述的发送单元 803具体可以为天线 4。
本实施例也并不局限于此， 其中如图 10中虚线所示， 也可以由天线 4接 收来自上一个微波节点的微波信号， 然后传送给天线 1， 再由天线 1发送给下 一个微波节点。 此时， 前述的接收单元 701则具体为天线 4， 而前述的发送单 元 803则具体为天线 1。
以上所述， 仅为本发明的具体实施方式， 但本发明的保护范围并不局限 于此， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可轻易 想到变化或替换， 都应涵盖在本发明的保护范围之内。 因此， 本发明的保护 范围应以权利要求所述的保护范围为准。
