为使本发明实施例的目的、 技术方案和优点更加清楚， 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。
本申请中涉及的基站可以是小基站， 还可以其他通用的基站， 例如： 可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的 设备。本发明实施例涉及的基站可以是时分双工（ Time Division Duplexing, 以下简称 TDD) 基站， 还可以是任意制式的基站， 例如， 基站可以是 GSM 制式或 CDMA制式的基站 （BTS， Base Transceiver Station) ， 也可以是 WCDMA制式的基站 （NodeB) ， 还可以是 TD-SCDMA制式的基站， 还可以是 LTE中的演进型基站 （NodeB或 eNB或 e-NodeB， evolut ional Node B ) ， 该 LTE演进型基站可以包括 TDD-LTE和 FDD-LTE制式的基站， 本申请并不 限定。 本发明实施例涉及的基站可以是小型化的上述各种制式的基站， 小型 化基站由于体积小， 因此可以灵活部署于热点、 盲点、 小区边缘甚至室内 区域， 提供网络的深度覆盖和容量扩充。 为了保证体积小， 小型化基站内 各天线通道的隔离度相对普通基站更低。
本申请适用于图 1所示的基站的驻波检测系统。 该驻波检测系统包括 多个天线， 即对应多个通道。 因此， 当多个天线分别接收到自己的前向信 号和后向信号时， 通过功放和多路选择开关之间的两个耦合器来采集这两 个信号， 其中， 一个耦合器采集前向信号， 另一个耦合器采集反向信号； 之后， 多路选择开关在现场可编程逻辑门阵列的控制下选择接入一个通 道， 这个通道内的所有信号经过频率变换器将高频信号转换为直流信号， 并经过模数转换后， 利用现场可编程逻辑门阵列将这两个信号提取出来， 送给中央处理器， 以获取驻波检测结果， 并根据驻波检测结果来确定基站 的器件性能是否稳定或器件是否老化等异常情况。 具体的， 本申请获取驻波 检测结果的具体实施例如下述所示：
本发明实施例一提供了一种基站， 该基站包括第一通道及第二通道， 所述第一通道为所述基站确定的任一待检测通道， 所述第二通道为所述基站 中除所述第一通道之外的其他通道。 具体的， 该基站包括： 处理器， 用于对 所述第一通道进行驻波检测； 其中， 在对所述第一通道进行驻波检测时， 所 述第二通道为关闭状态。
具体的， 处理器在对第一通道进行驻波检测之前， 需要确定第一通道。 可选的， 处理器可以根据基站的选择机制确定将上述至少两个通道中的哪一 个通道作为第一通道， gp， 可选的， 处理器可以根据基站自身架设的天线的 顺序依次确定第一通道， 例如： 假设基站有 1号、 2号、 3号 3个天线， 分别 对应 3个通道， 那么处理器首先将 1 号天线对应的通道确定为第一通道， 2 号和 3号天线对应的通道确定为第二通道； 待 1号天线对应的通道驻波检测 完成之后， 再将 2号天线对应的通道确定为第一通道， 以此类推。 可选的， 处理器也可以随机确定第一通道， 只要确保将基站所包括的所有通道都进行 驻波检测即可。
处理器确定第一通道之后， 在第一通道发功时 （即发射信号时） ， 确保 第二通道的状态是关闭的， 即保证在第一通道进行驻波检测时， 第二通道不 发功。 这样使得第二通道上发射功率不会耦合到第一通道上， 从而使得处理 器可以准确的获知第一通道的前向信号功率和后向信号功率。 可选的， 处理 器可以在任意时刻对第一通道进行驻波检测。
当当前的第一通道驻波检测完成之后， 处理器可以从剩余的第二通道中 继续选择一个通道作为第一通道， 按照上述实施例的过程完成所有通道的驻 本发明实施例提供的基站， 通过处理器在对当前选择的第一通道进行 驻波检测时， 确保第二通道为关闭状态， 避免在基站的各个天线隔离度较 低的情况下， 第二通道上的功率耦合到第一通道上。 采用本发明实施例提 供的基站， 降低了基站进行驻波检测时的干扰， 并且在进行驻波检测时， 关闭了基站内的其他通道，基站无需通过昂贵的解调电路来区分哪些是待检 测通道的功率， 哪些是其他通道耦合到待检测通道上的功率， 从而降低了基 站进行驻波检测的电路成本。
在上述实施例一的基础上， 作为本发明实施例的一种可能的实施方 式， 本实施例涉及的是处理器根据基带信号确定第一时间区域， 并在该第一 时间区域内进行驻波检测的具体过程。 具体的， 上述处理器， 还用于在对所 述第一通道进行驻波检测之前， 根据自身的基带信号确定第一时间区域； 其 中， 在所述第一时间域内， 所述基站的基带信号不承载数据信息； 并获取第 一信号， 根据所述第一信号， 在所述第一时间区域内采集到所述第一通道上 的前向信号和后向信号携带数据信息时的功率， 对所述第一通道进行驻波检 具体的， 由于基站的基带信号是连续的周期性信号， 因此处理器可以 根据基带信号上是否携带数据信息来确定基带信号在哪些时间段上不携 带数据信息， 这些时间段都可以看作是第一时间区域。 由于基带信号经过 射频处理后从第一通道发射出去， 那么处理器在第一通道上获取的前向信号 和后向信号实际上与基带信号是相关的， 即在第一时间区域内， 第一通道上 的前向信号和后向信号也没有承载数据业务， 即这两个信号在第一时间区域 内的电平值也为 0。 也就是说， 在该第一时间区域内， 基站的上下行信号的 电平值均为 0， 即没有通信业务。 因此， 在特定的第一时间区域内， 对第一 通道进行驻波检测， 不会影响基站与用户设备之间的通信。 由于在第一时间区域内， 处理器检测到的第一通道上的前向信号和后向 信号均没有承载数据业务， 即此时处理器检测到的前向信号和后向信号的功 率均为 0， 但这并不是处理器对第一通道进行驻波检测时所需要的前向信号 和后向信号的实际功率， 因为前向信号和后向信号的实际的功率为二者分别 携带数据信息时的功率。 因此， 处理器为了能够在第一时间区域内采集到前 向信号和后向信号携带数据信息时的功率， 可以从基站的射频部分获得第一 信号， 该第一信号为基站的射频部分发送的单音信号， 用于触发处理器能够 检测到前向信号和后向信号的实际功率， 即该单音信号可以使得基站在第一 时间区域内采集到前向信号和后向信号携带数据信息时的功率， 从而根据前 向信号和后向信号携带数据信息时的功率获得驻波检测结果。 由于此时基站 的其他通道是关闭的， 即其他通道上的功率不会耦合到第一通道上， 处理器 可以准确的得到第一通道上的前向信号和后向信号的功率。
当当前的第一通道驻波检测完成之后， 处理器可以从剩余的通道中继续 选择一个通道作为第一通道， 按照上述实施例的过程完成所有通道的驻波检 测。
本发明实施例提供的基站， 通过处理器在第一时间区域内对选择的第 一通道进行驻波检测时， 确保第二通道为关闭状态， 从而使得处理器在预 设的第一时间区域内可以根据所获取的第一信号对第一通道进行驻波检 测， 获得准确的驻波检测结果。 采用本发明实施例提供的基站， 降低了基 站进行驻波检测时的干扰， 并且在进行驻波检测时， 关闭了基站内的其他 通道， 基站无需通过昂贵的解调电路来区分哪些是待检测通道的功率， 哪些 是其他通道耦合到待检测通道上的功率，从而降低了基站进行驻波检测的电 路成本。 另外， 由于基站是在基带信号不携带数据信息的第一时间区域内 进行驻波检测， 也确保了基站与用户设备之间的通信不受影响。
可选的， 上述处理器， 可以用于在对所述第一通道进行驻波检测之前或 者在对所述第一通道进行驻波检测时， 关闭所述第二通道。 需要说明的是， 这里处理器关闭第二通道的时刻可以位于第一时间区域内， 也可以位于第一 时间区域之外， 只要确保处理器在对第一通道进行驻波检测时， 第二通道的 状态是关闭的即可。
进一歩地， 上述处理器， 具体用于在所述第一时间区域内， 且在对所述 第一通道进行驻波检测之前或在对所述第一通道进行驻波检测时， 关闭所述 第二通道。 需要说明的是， 这里处理器关闭第二通道的时刻需要位于第一时 间区域内。
进一歩地， 在上述实施例的基础上， 作为本发明实施例的另一种可能 的实施方式， 本实施例涉及的是基站为 TDD基站时， 处理器在无线帧的保 护间隔 （Guard Period, 以下简称 GP) 上对第一通道进行驻波检测的具体 过程。 具体的， 上述处理器， 具体用于根据所述第一信号， 在所述至少一 个 GP内的任一 GP上对所述第一通道进行驻波检测。
具体的， 上述的无线帧可以是一个无线帧， 也可以是循环的无线帧。 一 个无线帧可以包括 1个特殊的 TDD子帧， 特殊子帧上最多可以包括两个 GP， 每个 GP可以包括至少两个符号（symbol )， 一个 symbol的时间长度为 76us。 在一个 symbol的时间长度内至少可以进行一个第一通道的驻波检测。也就是 说， 上述处理器可以在至少一个 GP的任一 GP上对选定的第一通道进行驻波 检测。实际上在上述任一个 GP上可以分时进行多个通道的驻波检测。具体地， 假设将一个 GP内的某一个 symbol的时间长度分为第一时间段和第二时间段， 处理器控制其所确定的第一通道在第一时间段内发功， 且其他第二通道为关 闭状态， 处理器在该第一时间段内可以进行该第一通道的驻波检测； 之后， 处理器在该 symbol 的第二时间段内， 处理器控制其所确定的另一个第一通 道在第二时间段内发功， 且其他第二通道为关闭状态， 处理器在该第二时间 段内进行该另一个第一通道的驻波检测， 从而实现分时驻波检测。

具体的， 在无线帧的空闲时隙或预设的驻波测试时隙内， 处理器允许多 个通道在不同时间段发功， 即第一通道发功时， 确保其他第二通道是关闭 的状态， 此时进行第一通道的驻波检测， 并以此方式轮流检测基站所有的 通道。 可选的， 预设的驻波测试时隙可以是基站为驻波检测专门在无线帧 中选择的一段时隙。
本发明实施例提供的基站， 通过处理器在无线帧的空闲时隙或预设的 驻波测试时隙内， 对选择的第一通道进行驻波检测时， 确保第二通道为关 闭状态， 从而使得处理器在无线帧的空闲时隙或预设的驻波测试时隙内可 以根据所获取的第一信号对第一通道进行驻波检测， 获得准确的驻波检测 结果。采用本发明实施例提供的基站，降低了基站进行驻波检测时的干扰， 并且在进行驻波检测时， 关闭了基站内的其他通道， 基站无需通过昂贵的 解调电路来区分哪些是待检测通道的功率， 哪些是其他通道耦合到待检测通 道上的功率， 从而降低了基站进行驻波检测的电路成本。 另外， 由于基站 是在基带信号不携带数据信息的第一时间区域内进行驻波检测， 也确保了 基站与用户设备之间的通信不受影响。 本发明实施例二提供一种基站， 该基站包括第一通道及第二通道， 所 述第一通道为所述基站确定的任一待检测通道， 所述第二通道为所述基站中 除所述第一通道之外的其他通道。 具体的， 该基站包括： 检测模块 10， 用于 对所述第一通道进行驻波检测； 其中， 在对所述第一通道进行驻波检测时， 所述第二通道为关闭状态。
具体的， 检测模块 10在对第一通道进行驻波检测之前， 基站需要确定第 一通道。 可选的， 基站可以根据自身的选择机制确定将上述至少两个通道中 的哪一个通道作为第一通道， gp， 可选的， 基站可以根据基站自身架设的天 线的顺序依次确定第一通道， 例如： 假设基站有 1号、 2号、 3号 3个天线， 分别对应 3个通道， 那么基站首先将 1号天线对应的通道确定为第一通道， 2 号和 3号天线对应的通道确定为第二通道； 待 1号天线对应的通道驻波检测 完成之后， 再将 2号天线对应的通道确定为第一通道， 以此类推。 可选的， 基站也可以随机确定第一通道， 只要确保将基站所包括的所有通道都进行驻 波检测即可。
检测模块 10在基站确定第一通道之后， 在第一通道发功时（即发射信号 时） ， 确保第二通道的状态是关闭的， 即保证在第一通道进行驻波检测时， 第二通道不发功。 这样使得第二通道上发射功率不会耦合到第一通道上， 从 而使得检测模块 10 可以准确的获知第一通道的前向信号功率和后向信号功 率。 可选的， 检测模块 10可以在任意时刻对第一通道进行驻波检测。
当当前的第一通道驻波检测完成之后，检测模块 10可以从剩余的第二通 道中继续选择一个通道作为第一通道， 按照上述实施例的过程完成所有通道 的驻波检测。
本发明实施例提供的基站， 通过检测模块在对基站选择的第一通道进 行驻波检测时， 确保第二通道为关闭状态， 避免在基站的各个天线隔离度 较低的情况下， 第二通道上的功率耦合到第一通道上。 采用本发明实施例 提供的基站，降低了基站进行驻波检测时的干扰，并且在进行驻波检测时， 关闭了基站内的其他通道，基站无需通过昂贵的解调电路来区分哪些是待检 测通道的功率， 哪些是其他通道耦合到待检测通道上的功率， 从而降低了基 站进行驻波检测的电路成本。

具体的， 由于基站的基带信号是连续的周期性信号， 因此确定模块 11 可以根据基带信号上是否携带数据信息来确定基带信号在哪些时间段上 不携带数据信息， 这些时间段都可以看作是第一时间区域。 由于基带信号 经过射频处理后从第一通道发射出去， 那么基站在第一通道上获取的前向信 号和后向信号实际上与基带信号是相关的， 即在第一时间区域内， 第一通道 上的前向信号和后向信号也没有承载数据业务， 即这两个信号在第一时间区 域内的电平值也为 0。 也就是说， 在该第一时间区域内， 基站的上下行信号 的电平值均为 0， 即没有通信业务。 因此， 在特定的第一时间区域内， 检测 模块 10对第一通道进行驻波检测， 不会影响基站与用户设备之间的通信。
由于在第一时间区域内，检测模块 10检测到的第一通道上的前向信号和 后向信号均没有承载数据业务，即此时检测模块 10检测到的前向信号和后向 信号的功率均为 0， 但这并不是检测模块 10对第一通道进行驻波检测时所需 要的前向信号和后向信号的实际功率， 因为前向信号和后向信号的实际的功 率为二者分别携带数据信息时的功率。 因此， 检测模块 10为了能够在第一时 间区域内采集到前向信号和后向信号携带数据信息时的功率， 可以通过获取 模块 11从基站的射频部分获得第一信号，该第一信号为基站的射频部分发送 的单音信号，用于触发检测模块 10能够检测到前向信号和后向信号的实际功 率，即该单音信号可以使得检测模块 10在第一时间区域内采集到前向信号和 后向信号携带数据信息时的功率， 从而根据前向信号和后向信号携带数据信 息时的功率获得驻波检测结果。 由于此时基站的其他通道是关闭的， 即其他 通道上的功率不会耦合到第一通道上，检测模块 10可以准确的得到第一通道 上的前向信号和后向信号的功率。
当当前的第一通道驻波检测完成之后， 基站可以从剩余的通道中继续选 择一个通道作为第一通道，检测模块 10继续按照上述实施例的过程完成所有 通道的驻波检测。
本发明实施例提供的基站， 通过检测模块在确定模块确定的第一时间 区域内， 对基站选择的第一通道进行驻波检测时， 确保第二通道为关闭状 态， 从而使得检测模块在第一时间区域内可以根据获取模块所获取的第一 信号对第一通道进行驻波检测， 获得准确的驻波检测结果。 采用本发明实 施例提供的基站， 降低了基站进行驻波检测时的干扰， 并且在进行驻波检 测时， 关闭了基站内的其他通道， 基站无需通过昂贵的解调电路来区分哪 些是待检测通道的功率， 哪些是其他通道耦合到待检测通道上的功率， 从而 降低了基站进行驻波检测的电路成本。 另外， 由于基站是在基带信号不携 带数据信息的第一时间区域内进行驻波检测， 也确保了基站与用户设备之 间的通信不受影响。

图 4为本发明提供的基站驻波检测方法实施例二的流程示意图。 本实施 例涉及的方法是基站根据基带信号确定第一时间区域， 并在该第一时间区域 内进行驻波检测的具体过程。 如图 4所示， 该方法包括：
S101 : 基站根据自身的基带信号确定第一时间区域； 其中， 在所述第一 时间域内， 所述基站的基带信号不承载数据信息。
具体的， 由于基站的基带信号是连续的周期性信号， 因此基站本身可 以根据基带信号上是否携带数据信息来确定基带信号在哪些时间段上不 携带数据信息， 这些时间段都可以看作是第一时间区域。
基站的基带信号在第一时间区域内不承载任何数据信息， 即基站的基带 信号在第一时间区域内的电平值为 0。 由于基带信号经过射频处理后从第一 通道发射出去， 那么基站在第一通道上获取的前向信号和后向信号实际上与 基带信号是相关的， 即在第一时间区域内， 第一通道上的前向信号和后向信 号也没有承载数据业务， 即这两个信号在第一时间区域内的电平值也为 0。 也就是说， 在该第一时间区域内， 基站的上下行信号的电平值均为 0， 即没 有通信业务。 因此， 在特定的第一时间区域内， 对第一通道进行驻波检测， 不会影响基站与用户设备之间的通信。
S102 : 基站获取第一信号。
具体的， 该第一信号为基站的射频部分发送的单音信号， 用于触发基站 能够检测到前向信号和后向信号的实际功率。
S103 : 基站根据所述第一信号， 在所述第一时间区域内采集到所述第一 通道上的前向信号和后向信号携带数据信息时的功率， 对所述第一通道进行 驻波检测。
具体的， 由于在第一时间区域内， 基站检测到的第一通道上的前向信号 和后向信号均没有承载数据业务， 即此时基站检测到的前向信号和后向信号 的功率均为 0， 但这并不是基站对第一通道进行驻波检测时所需要的前向信 号和后向信号的实际功率， 因为前向信号和后向信号的实际的功率为二者分 别携带数据信息时的功率。 因此， 基站为了能够在第一时间区域内采集到前 向信号和后向信号携带数据信息时的功率， 可以从基站的射频部分获得单音 信号， 该单音信号可以使得基站在第一时间区域内采集到前向信号和后向信 号携带数据信息时的功率， 从而根据前向信号和后向信号携带数据信息时的 功率获得驻波检测结果。 由于此时基站的其他通道是关闭的， 即其他通道上 的功率不会耦合到第一通道上， 基站可以准确的得到第一通道上的前向信号 和后向信号的功率。
