Because the parameter configuration of the upper-level network element, the micro-base station operates with the same configuration parameters as the macro-base station of the macro-cell in which it is located. Therefore, for the same traffic channel, the usage rules of the micro-base station and the macro base station using the same configuration parameters for the service channel are also Similarly, the detection result of the same base station and the macro base station for the same traffic channel may also be considered as being sent by the same UE.
- the micro base station can estimate the uplink interference estimation of the UE to the local base station by using the uplink signal from the UE detected by the base station of the service channel on the traffic channel. Therefore, the uplink interference estimator is offset in the uplink signal of the traffic channel received by the micro base station, so as to reduce the uplink interference.
- the antenna of the micro base station receives the uplink signal S_in(t) of all UEs in the working range of the micro base station, For the UE in which the service is not carried by the micro base station, the micro base station may obtain the uplink of the part of the UE to the base station from the related data that is reported to the upper-level network element by the base station that performs the service bearer for the part of the UE.

- the step S702 determining whether D(i) is greater than a preset threshold may also be performed by each base station before reporting the channel detection result, and each base station determines the signal output of each traffic channel detected by the base station. Whether the value D (i) is greater than the preset threshold, so that the detection result is self-introduced
- the filtering is performed, and the filtered detection result is reported to the upper-level network element.
- the upper-level network element does not need to perform the judgment process of S702, and directly stores the obtained detection result in the corresponding position of Table 2.

在 S202 中， 所述 基站将所述扫描结果上才艮给上级网元， 所述扫描结果 中包括了所述接收机扫描到的小区的信号强度， 以使所述上级网元根据所述扫 描结果确定出对所述微基站信号强度最强的小区， 并将该小区的配置参数配置 给所述微基站。
在微基站将扫描结果上报给其上级网元之后，上级网元会根据该扫描结果， 识别出对该微基站信号强度最强的小区， 以该小区的配置参数为基础， 将配置 参数中的小区标识修改为该微基站的小区标识， 从而将修改后的这套配置参数 配置给该微基站， 以使该微基站根据这套配置参数开工运行。
具体地， 在微基站的上级网元中， 为微基站进行参数配置的流程可以如图 4所示：
在 S401中，接收微基站上报的扫描结果，所述扫描结果中包括了该微基站
通过接收机扫描到的小区的信号强度。
在 S402中， 根据所述扫描结果， 确定出对所述微基信号强度最强的小区。 具体地， 上级网元可以从扫描结果中获取到信号强度最强的小区的小区标 识， 从而确定出对微基站信号强度最强的小区。
在 S403中， 获取所述对所述微基站信号强度最强的小区的配置参数。 在 S404中，将获取到的配置参数配置给所述微基站， 以使所述微基站根据 所述获取到的配置参数运行。
具体地，在 S403获取到对微基站信号强度最强的小区的配置参数之后，通 过将该配置配置参数中的小区标识修改为微基站的小区标识， 从而生成微基站 的配置参数。
在本实施例中， 当上级网元在为 基站配置了配置参数之后， 上级网元还 通过将该微基站的小区标识与对该微基站信号强度最强的小区的小区标识进行 关联， 以时刻保证上述两个基站配置有相同的配置参数， 一旦对该微基站信号 强度最强的小区的配置参数发生了变化， 则上级网元也对该微基站的配置参数 进行重配置， 使微基站的配置参数也作出相应变化。
通常， 对微基站信号强度最强的小区即为与该微基站进行同频组网的宏小 区。 上述小区标识的关联过程可以如下： 生成微基站的配置参数之后， 在上级 网元中存储相应的关联关系表， 如表 1所示：
表 1
其中， Site name ( i )表示第 i个基站名， Cell ID ( i )表示和第 i个基站对 应的小区标识。
通过图 4所示的实施例， 依据微基站的扫描结果， 上级网元自动为该微基 站生成与其相关的宏基站的配置参数， 不需要额外的配置操作， 从而筒化了网 络规划操作， 实现了微基站真正意义上的即插即用。
需要说明的是， 图 4所述实施例适用于微基站部署在多个宏基站的覆盖区 域内的情况， 若微基站仅部署在一个宏基站的覆盖区域内， 则微基站的配置参 数直接为与该宏基站完全相同的配置参数（除了小区标识） ； 而若微基站在接 收机扫描过程中没有检测到其他小区， 则微基站按照普通微基站自动规划的方 式配置参数， 即， 为该微基站选择一个已经开工的宏基站的配置参数， 自动生 成该微基站的配置参数， 微基站按照自动生成的配置参数开工。
在 S203 中， 所述微基站在根据所述上级网元配置的配置参数运行之后， 分别判断每个业务信道当前是否由所述微基站进行业务承载。
在 S204 中， 对于当前不由所述微基站进行业务承载的业务信道， 所述微 基站获取在该业务信道上 UE对所述微基站的上行干扰估计量， 并在接收到的 该业务信道的上行信号中抵消所述上行干扰估计量。
在本实施例中， 对于当前不由微基站进行业务承载的业务信道， 则该微基 站不需要接收到接入该业务信道的 UE的上行信号， 此时， 需要对这部分上行 信号进行消除。 由于通过上级网元的参数配置， 微基站与其所处宏小区的宏基 站采用相同的配置参数运行， 因此， 对于相同业务信道， 采用相同配置参数的 微基站与宏基站对业务信道的使用规律也相同， 该微基站与宏基站对于同一业 务信道的检测结果也可以被认为是相同 UE发出的。 基于上述相同配置参数的 运行环境， 微基站能够通过对该业务信道进行业务承载的基站在该业务信道上 所检测到的来自 UE的上行信号，来估计出 UE对本微基站的上行干扰估计量， 从而在微基站接收到的该业务信道的上行信号中抵消这部分上行干扰估计量， 达到减少上行干扰的目的。
具体地， 在当前时刻 t, 对于微基站来说， 在某个业务信道 n上， 通过该微 基站的天线会接收到该微基站工作范围内的所有 UE的上行信号 S_in ( t ) , 同
时， 对于其中并不由该微基站进行业务承载的 UE, 微基站可以从对这部分 UE 进行业务承载的基站所上报给上级网元的相关数据中， 获取到这部分 UE对其 承载基站的上行信号， 并将该上行信号估计为这部分 UE对该微基站的上行信 号， 从而获取到这部分 UE的上行信号总和∑S'_out, 这部分上行信号总和即为 该业务信道上 UE对敫基站的上行干扰估计量， 因此， 将 S_in ( t ) -∑S'_out, 即实现了对该业务信道上的上行干扰信号的抵消。
图 2实施例所述方法需要每个基站循环检测每个业务信道， 以保持上行干 扰信号的消除， 基站的其中一个循环过程可以如图 5所示：
在 S501中， 初始化业务信道号 n=0。
在 S502中， 判断业务信道 n是否由本基站进行业务承载， 是则 n=n+l , 重 复执行 S502, 否则执行 S503。
在 S503中， 获取对业务信道 n的上行干扰估计量。
在 S504中，获取业务信道 n上该微基站工作范围内的所有 UE的上行信号。 在 S505中， 在上行信号中抵消上行干扰估计量。
在 S506中， η=η+1 , 若 n=n ( max ) , 则 η=0, 重复执行 S502。
在本实施例中， 微基站的接收机始终处于运行状态， 用于实时地对上行信 道进行检测。
本发明实施例中， 基站与其所处宏小区的宏基站采用相同的配置参数运 行， 在该运行条件下， 微基站通过及时地估计由 UE产生的上行干扰， 从而在 接收到的上行信号中减去上行干扰信号， 由此减少了由 UE产生的上行干扰， 提高了网络吞吐量。
同时， 基于宏基站与其覆盖范围内迭加的一个或多个微基站同频部署的网 络架构， 针对基站工作过程中存在的下行干扰， 能够根据 UE与各基站之间的 信号传播损耗来确定该 UE与其中一个基站进行业务连接， 从而关闭与该 UE 非业务连接的基站在相关业务信道上的发射机， 减少网络下行干扰， 提高网络 吞吐量。
图 6示出了本发明另一实施例提供的宏微基站同频组网的干扰控制方法的 实现流程， 在本实施例中， 执行主体为同频组网的各基站的上级网元， 详述如 下：
在 S601中，接收基站上报的所述基站对每个业务信道进行信号输出检测的 检测结果， 所述基站包括宏基站或微基站。
在本实施例中， 每个基站均会依次对每个业务信道进行信号输出检测， 以 获取到该基站对每个业务信道的检测结果， 并将检测结果一一上报给其上级网 元。
在 S602中， 根据所述检测结果确定所述基站是否在所述业务信道上对 UE 进行业务承载。
在每个基站上报的检测结果中， 若存在某个业务信道的检测结果大于预设 门限， 则表明该基站在该业务信道上检测到了 UE接入， 否则， 表明该基站在 该业务信道上没有检测到 UE接入。
具体地，根据检测对象的不同，获取到的检测结果可以包括以下任意一项： 在业务信道上检测到的信号与干扰加噪声比 （Signal to Interferenceplus Noise Ratio, SINR ) 、 信号干 4尤比（ Signalto Interference Ratio , SIR ) 、 参考信号接 收功率（ Reference Signal Receiving Power, RSRP ) 。 以 SINR为例， 当有 UE 接入该业务信道时， 在该业务信道上检测到的 SINR就会增大很多， 高于某一 预设阈值； 而当没有 UE接入该业务信道时， 基站在该业务信道上只检测到底 噪。 若检测结果为 SIR或者 RSRP时， 基本也是基于相同的上述原理来判断是 否有 UE接入业务信道。
由此， 根据接收到的每个基站上报的检测结果， 上级网元即能够在所有业 务信道中确定出同时被多个基站中的一个以上基站检测出有 UE接入的业务信 道。
在具体实现中， 可以在上级网元建立如表 2所示的表格， 用于管理基站上 报的检测结果， 其中， Site ID为基站标识， Cell ID为小区标识， D ( i ) 为
第 n个业务信道的信号输出值
表 2
S701:读取检测结果中第 i个业务信道的信号输出值 D(i),初始化时 i=l。
S702: 判断 D (i)是否大于预设门限， 是则执行 S703, 否则 i+1, 重复执 行 S701。
S703: 将 D (i)以及上报该信道检测结果的基站的基站标识及其对应的小 区标识存储在表 2的相应位置， 之后 i+1, 重复执行 S701。
通过图 7所示步骤， 直至读取完该基站上报的检测结果中所有的信号输出 值， 即完成了对表 2的一次存储或者更新。
表 2在建立完成之后， 上级网元可以根据基站的上报情况， 对表 2进行实 时的更新、 维护， 且一旦有新的 UE进行业务连接， 也能够被及时地发现， 以 使上级网元及时为新的 UE确定业务承载基站。
作为本发明的一个实施例， S702判断 D ( i )是否大于预设门限的步骤也可 以由各个基站在将信道检测结果上报之前执行， 各个基站通过判断其检测到的 每个业务信道的信号输出值 D (i)是否大于预设门限， 从而自行对检测结果进
行过滤，并将过滤后的检测结果上报给上级网元，上级网元无需执行 S702的判 断过程， 直接将获取到的检测结果存储在表 2的相应位置。
在本实施例中， 当在某条业务信道上检测出有 UE接入的基站只有一个时， 则显然， 对该 UE在该业务信道上进行业务承载的一定是该基站， 而当在某条 业务信道上检测出有 UE接入的基站有多个时，则根据 S601接收到的每个基站 对每个业务信道的检测结果， 在这多个基站中将关于该业务信道的检测结果最 大的基站确定为承载基站， 该承载基站用于对该 UE在该业务信道上进行业务 承载。
在 S603中， 对于所述基站未对 UE进行业务承载的所述业务信道， 通知所 述基站关闭在该业务信道上的发射功率。
在确定了基站未对 UE进行业务承载的所有业务信道之后， 通知基站关闭 其发射机在该业务信道上发射功率， 由此， 不会出现该 UE同时与多个基站建 立业务连接， 在一个业务信道上同时存在多条无线链路， 产生网络干扰， 进而 导致其中部分无线链路失效的情况出现， 提高了网络吞吐量。
图 8示出了本发明另一实施例提供的宏微基站同频组网的干扰控制方法的 实现流程图， 在本实施例中， 流程的执行主体为图 1中的基站 （宏基站或者微 基站） ， 详述如下：
在 S801中， 基站对每个业务信道进行信号输出检测， 得到检测结果。 在本实施例中， 基站按照业务信道号， 依次对每个业务信道进行信号输出 检测， 获取到每个业务信道的检测结果。 其中， 检测结果可以包括以下任意一 项： 在业务信道上检测到的 SINR、 SIR, RSRP。
作为本发明的一个实施例，基站也可以对 S801获取到的检测结果进行过滤 之后再上报给其上级网元。 具体地， 基站通过判断其检测到的每个业务信道的 检测结果是否大于预设门限， 从而自行对检测结果进行过滤， 将大于预设门限 的检测结果上报给上级网元。
在 S802 中， 所述基站将所述检测结果上报给所述基站的上级网元， 以使
所述上级网元根据所述检测结果， 确定所述基站是否在所述业务信道上对 UE 进行业务承载。 通知所述基站是否进行业务承载。
在本实施例中，在基站将 S801生成的信道检测结果上报给其上级网元之后 , 上级网元可以依据获取到的该基站上报的检测结果以及该上级网元之下的其他 基站依据相同的方法上报的检测结果， 如本发明前述实施例所述， 确定基站是 否在该业务信道上对 UE进行业务承载。
其中， 当在某条业务信道上检测出有 UE接入的只有本基站一个时， 则显 然， 对该 UE在该业务信道上进行业务承载的一定是本基站。 而当在某条业务 信道上检测出有 UE接入的基站除了本基站， 还有其他基站时， 则这些基站的 上级网元根据接收到的关于该业务信道的所有检测结果， 在这多个基站中将关 于该业务信道的检测结果最大的基站确定为对 UE进行业务承载。
在本实施例中，对于某条业务信道，若本基站在 S901进行信号输出检测时， 没有检测到大于预设门限的检测结果， 则表示本基站当前并不对 UE在该业务 信道上进行业务承载， 则本基站可以直接关闭其接收机在该业务信道上的发射 功率。
在 S803中， 对于所述基站未对 UE进行业务承载的所述业务信道， 所述基 站接收所述上级网元的通知， 关闭其在该业务信道上的发射功率。
在本实施例中， 对于该基站不需要对 UE进行业务承载的业务信道， 则该 基站关闭接收机在该业务信道上的发射功率， 即该基站在该业务信道上不进行 发射， 减少整个同频组网系统的下行发射功率， 进而减少下行干扰， 增加了系 统的吞吐量。
本发明实施例基于宏基站与其覆盖范围内迭加的一个或多个微基站同频部 署的网络架构， 能够根据 UE与各基站之间的信号传播损耗来确定该 UE与其 中一个基站进行业务连接， 从而关闭与该 UE非业务连接的基站在相关业务信 道上的发射机， 减少网络干扰， 提高网络吞吐量。
