Description

终端控制方法、 无线网络控制器和基站
技术领域
本发明实施例涉及通信技术， 尤其涉及一种终端控制方法、 无线网络 控制器和基站。 背景技术
在异构网 （Heterogeneous Network, 简称： Hetnet) 中， 宏站和微站的下 行发射功率不同， 造成宏站的下行覆盖半径与微站的下行覆盖半径不同， 通 常宏站的下行覆盖半径大于微站的下行覆盖半径； 但是由于同一终端 （UE) 向宏站和微站发送上行信号的上行发射功率是相同的， 所以宏站和微站的上 行覆盖半径是相等的， 这种情况就是 Hetnet中的上下行覆盖不平衡的问题。
由于上下行覆盖不平衡，在 Hetnet的切换区中的 UE容易出现如下问题: 切换区 UE的功率是由上行信号质量较好的微站来控制的， 微站会在接收到 的 UE上行信号质量高于门限时指示 UE降低上行发射功率；而 UE的服务基 站是由下行信号质量决定，对于切换区内的宏站下行信号质量较优的 UE， 其 服务基站是宏站； 但是， UE向宏站的上行信号本来就较差， 即 UE向宏站的 上行信号质量低于向微站的上行信号质量， 且微站又指示 UE降低上行发射 功率， 将可能导致 UE对宏站的上行失歩， 即可能与宏站断开通信连接。 发明内容

图 14为本发明实施例提供的 RNC的实体结构示意图；
图 15为本发明实施例提供的基站的实体结构示意图。 具体实施方式 本发明实施例提供了一种终端控制方法， 该方法可以应用于对异构网切 换区内的终端进行上行发射功率的控制。 图 1为本发明实施例提供的终端控 制方法的应用网络示意图， 该图 1示出的是 Hetnet网络， 包括宏站 （Macro) 和微站（Micro )， 该宏站和微站的上行边界（UL boundary)和下行边界（DL boundary) 是不同的。 图 1中还示出了分别位于宏站和微站之间的不同区域 内的几个终端，包括： UE1至 UE6,其中的 UE4和 UE5位于切换区（SHO area) , UE3位于非切换区（Non-SHO area)。图 1中还示出了无线网络控制器（Radio Network Controller, 简称： RNC) ， 该 RNC可以与宏站和微站均建立通信。
首先对图 1所示的场景做简单说明如下： 切换区通常是在图 1中所示的 下行边界附近， 具体的， 更加靠近宏站的终端例如 UE1 , 其只与宏站建立上 下行通信连接， 并且 UE1的上行发射功率由宏站控制； 而随着终端逐渐向右 移动， 即逐渐远离宏站并向微站靠近的过程中， 终端会不断测量其所接收到 的基站的下行信号强度， 并根据该信号强度决定是否与基站建立连接。 比如 UE3 , 在图 1中所示的 UE3的位置处， 终端测量的宏站和微站的信号强度相 差较大， 即微站的信号还是比较弱的， 所以在该位置 UE3仍然是只与宏站连 接， 受宏站控制。但是到了 UE4的位置， 此时 UE4测量到微站的信号强度已 经增强， 决定同时建立与微站的连接 （但是此时的服务基站仍然是宏站， 因 为服务基站是下行信号更强的基站） ， 所以 UE4与宏站和微站都已经建立上 行连接。此时，宏站和微站都会根据接收到的 UE4上行信号决定对 UE4的上 行功率调整， UE4将会接收到两个功率调整指令， 一个是宏站发送的， 一个 是微站发送的。 UE4的原则是， 如果两个指令都是指示提高功率则提高功率， 如果两个指令中有一个是指示降低功率则降低功率。 同理， UE5也处于切换 区内， 与两个基站都有连接， 只是服务基站已经转为微站； UE6就是只与微 站具有连接了。 以上只是简单说明， 均是常规技术， 本实施例不再详述。
本发明实施例所提供的终端控制方法， 可以用于避免异构网切换区中的 终端发生上行失歩， 这里可能出现上行失歩的终端是图 1中所示的 UE4, 首 先， UE4位于宏站的下行覆盖区域内 （即下行边界靠近宏站一侧） ， 所以对 于 UE4来说，宏站的下行信号质量优于微站的下行信号质量，所以 UE4的下 行服务基站是宏站； 但是， UE4的上行最优链路是微站 （即上行边界靠近微 站一侧的区域），所以微站接收 UE4的上行信号质量优于宏站接收 UE4的上 行信号质量。 可能出现的情况是， 微站由于接收的 UE4上行信号质量较好而 指示 UE4降低上行发射功率，从而造成 UE4向服务基站宏站发射的上行信号 质量更差而导致在宏站侧失歩。 本发明实施例的终端控制方法就是为了避免 UE4产生上述的失歩问题， 详细可以参见下面对于控制方法的描述。 而对于 图 1中所示的其他 UE， 比如 UE5和 UE3不会出现上述失歩问题， 因为 UE3 不在切换区， 微站不能控制其发射功率， 而 UE5已经选择微站为服务基站， 微站会保证其上行信号的质量。
实施例一
图 2为本发明实施例提供的一种终端控制方法的流程示意图， 该方法是 以 RNC为执行主体进行描述， 如图 2所示， 该方法可以包括：
201、 RNC确定与宏站和微站均建立连接的终端的下行服务基站为宏站； 其中， UE进入切换区后， 在切换区内， UE与宏站和微站都具有通信连 接， 并且 UE将在 RNC的控制下进行基站之间的切换， 比如 UE向 RNC上 报基站下行信号测量报告， 该报告中可以包括 UE测量到的基站下行信号的 强度， 例如， 包括宏站下行信号强度和微站下行信号强度， RNC根据该信号 强度指示 UE进入哪个基站区域。 那么在此过程中， RNC是能够得知 UE的 下行服务基站是哪个基站的， 比如本实施例中， RNC可以获知 UE4的下行服 务基站是宏站，继续执行 202;而如果 RNC获知 UE5的下行服务基站是微站， 将结束本次流程， 不再执行后续歩骤。
202、 RNC获取目标功控值， 所述目标功控值用于保证所述终端在宏站 的上行控制信道的信道质量达到目标门限；
可选的， 该目标功控值例如是从宏站获取的能控制终端在宏站的上行控 制信道的信道质量达到目标门限的目标信噪比 （ Signal to Interference Ratio target, 简称： SIR target) 。本实施例中， 只要信道质量达到所述的目标门限， 就可以保证终端在宏站的上行控制信道不会出现上行失歩。
可选的， 该目标功控值也可以按照如下方式得到： RNC分别获取第一功 控参考值和第二功控参考值；
其中， 所述的第一功控参考值用于保证终端在宏站的上行控制信道的最 低信道质量， 第二功控参考值用于保证终端在宏站的上行数据信道的最低信 道质量。 可选的， 以上述两个功控参考值是目标信噪比为例， 第一功控参考 值是第一目标信噪比 （SIR target) ， 第二功控参考值是第二目标信噪比。 第 一目标信噪比的设置值是用于控制 UE4在宏站的上行控制信道的信道质量达 到目标门限； 第二目标信噪比的设置值是用于控制 UE4在宏站的上行数据信 道的信道质量达到目标门限。
RNC从所述第一功控参考值和第二功控参考值中选择其中之一作为目标 功控值。 具体的， RNC选取的目标功控值能用于同时保证终端向宏站的上行 控制信道和上行数据信道的信道质量达到目标门限； 如果以 202中的 SIR target为例， 那么本歩骤中 RNC要从第一目标信噪比和第二目标信噪比中选 择较大值作为目标功控值。
更具体的举例如下：第一目标信噪比是 al，第二目标信噪比是 a2， al>a2, 如果选择 a2作为目标功控值， 当基站根据该目标功控值控制 UE的上行发射 功率时，当基站测量的上行信道的 SIR target高于 a2，比如介于 al和 a2之间， 则基站将指示 UE降低其发射功率， 但是此时， al对应的上行控制信道尚未 达到最低信道质量的要求， 信号质量很差， 是有可能掉线的， 如果进一歩降 低 UE的发射功率， 将会使得上行控制信道的质量更差， 出现失歩。 而假设 选择 al作为目标功控值， 当基站根据该目标功控值控制 UE的上行发射功率 时， 对于介于 al和 a2之间的某个测量值 SIR target, 由于尚未达到目标功控 值， 基站将指示 UE提高发射功率， 以达到信道最低质量要求， 并且功率提 升后，对 a2对应的上行控制信道不会产生影响，已经满足了其信道质量要求。 所以， 所选择的目标功控值要能同时满足终端在宏站的上行控制信道和上行 数据信道的信道质量达到目标门限。
203、 RNC将所述目标功控值发送至微站。
本歩骤中， RNC将 202中选取的目标功控值分别发送给微站， 以使得微 站根据所述目标功控值对终端的上行发射功率进行控制。 仍以图 1中的 UE4 为例， UE4的功率控制更多是由微站来决定的， 宏站此时基本是抬升功率， 所以微站根据所述的目标功控值对 UE进行功控， 可以保证宏站处的上行控 制信道的最低信道质量， 防止出现失歩问题。 可选的， 该目标功控值也可以 发送至宏站。
本实施例提供的终端控制方法， 由于用以对终端进行上行发射功率控制 的目标功控值， 是考虑到宏站的上行控制信道和上行数据信道的信道质量综 合确定的， 该目标功控值能够用于同时保证终端在宏站的上行控制信道和上 行数据信道的信道质量达到目标门限， 所以当微站根据该目标功控值对终端 进行上行发射功率的控制时，是必定不会出现现有技术中的用户失歩问题的， 避免了异构网切换区的终端发生上行失歩。
实施例二
图 3为本发明实施例提供的另一种终端控制方法的流程示意图， 该方法 是以微站为执行主体进行描述； 如图 3所示， 该方法可以包括：
301、 微站获取 RNC发送的目标功控值， 所述目标功控值用于保证终端 在宏站的上行控制信道的信道质量达到目标门限；
可选的，基站获取的目标功控值可以是 RNC从第一功控参考值和第二功 控参考值中选择确定的。 例如， 所述第一功控参考值用于保证所述终端在宏 站的上行控制信道的信道质量达到目标门限， 所述第二功控参考值用于保证 终端在宏站的上行数据信道的信道质量达到目标门限， 选取的所述目标功控 值能用于同时控制终端在宏站的上行控制信道和上行数据信道的信道质量达 到目标门限。
302、微站根据所述目标功控值对终端的上行发射功率进行控制， 所述终 端与宏站和微站均建立连接， 且所述终端的下行服务基站是所述宏站；
其中， 该功控针对异构网切换区内的下行服务基站是宏站的终端， 即图 1中的 UE4; 而本实施例的方法可以是图 1中的微站执行的。 具体可以参见 实施例一， 不再详述。
本实施例中微站据以控制的现目标信噪比 （本实施例的目标功控值） 是 RNC综合考虑上行数据信道和宏站上行控制信道的信道质量而确定的， 能够 同时保证这两个信道质量， 所以现目标信噪比相比于原目标信噪比将略高， 从而采用本实施例方法后的 UE4的上行发射功率也将比现有技术中的功率提 高， UE4的发射功率提高将进而改善 UE4向宏站的上行控制信道的质量， 避 免上行失歩。
本实施例提供的终端控制方法， 由于用以对终端进行上行发射功率控制 的目标功控值， 是考虑到宏站的上行控制信道和上行数据信道的信道质量综 合确定的， 该目标功控值能够用于同时保证终端在宏站的上行控制信道和上 行数据信道的信道质量达到目标门限， 所以当微站根据该目标功控值对终端 进行上行发射功率的控制时，是必定不会出现现有技术中的用户失歩问题的， 避免了异构网切换区的终端发生上行失歩。
实施例三
图 4为本发明实施例提供的又一种终端控制方法的信令示意图， 本实施 例重点描述 RNC获取第一功控参考值的其中一种方式， 其他歩骤简单描述， 具体可以结合参见实施例一和实施例二。 如图 4所示， 该方法可以包括：
401、 RNC确定与宏站和微站均建立连接的终端的下行服务基站为宏站； 本实施例中， RNC可以获知 UE4的下行服务基站是宏站，继续执行 402。
402、 RNC接收宏站发送的上行控制信道的目标信道测量指标值， 并将 与所述目标信道测量指标值对应的功控值作为第一功控参考值；
可选的，本歩骤中 RNC确定第一功控参考值具体可以是按照如下的方式 执行： 首先， 宏站定期向 RNC上报信道测量指标值， 或者也可以是， 宏站在 接收到 RNC发送的指标获取请求时发送。 所述的上行控制信道是 UE4向宏 站的上行控制信道； 所述的信道测量指标值例如是， TPC检测概率、 CQI检 测概率、 Pilot BER或者 TFCI漏检参考指示值等， 宏站在接收到 UE4发送的 上行控制信息时， 是可以得到上述的信道测量指标值的； 并且宏站向 RNC可 以上报这些测量值中的至少一个。 接着， RNC可以根据接收到的宏站发送的 信道测量指标值， 来调整 RNC自身设置的当前的功控值， 调整功控值之后， 将该功控值发送至宏站据以控制终端功率， 则再次从宏站接收的信道测量指 标值也会随着上述功控值的调整而变化，直至得到 RNC所期望的信道测量指 标值即目标信道测量指标值，此时 RNC可以将与目标信道测量指标值相对应 的功控值作为目标功控值， 在本实施例中， 该目标功控值可以称为第一功控 参考值。
举例说明如下：假设当前 RNC接收到的宏站发送的信道测量指标值 TPC 检测概率是 95%， 但是有可能是 TPC检测概率是 99%时， 对应的信道质量才 是比较好的， 所以我们可以将 99%的 TPC检测概率称为 "目标信道测量指标 值" ， 据此调整当前的功控值 SIR target; 那么该例子中， 95%小于目标信道 测量指标值， 则调整当前的 SIR target, 调整后重新观察信道测量指标值的变 化， 比如可能是由 95%上升到了 97%， 逐渐向目标信道测量指标值趋近。 接 着再调整 SIR target,直至观察到的信道测量指标值达到目标信道测量指标值， 则将此时对应的 SIR target作为第一功控参考值。
403、 RNC获取第二功控参考值；
其中， 第二功控参考值用于保证终端在宏站的上行数据信道的信道质量 达到目标门限。 实际上， 该第二功控参考值可以用于同时保证终端在宏站和 微站的上行数据信道的信道质量达到目标门限， 只是切换内的终端向微站的 上行数据信道质量优于宏站信道质量， 如果能保证宏站的上行数据信道的信 道质量， 则也能够保证微站信道质量。
本歩骤中 RNC获取第二功控参考值例如第二目标信噪比的方式，可以采 用常用方法即可，例如由宏站和微站向 RNC上报块误码率 (Block Error Ratio, 简称： BLER) ， RNC综合根据上报的 BLER确定要采用的第二目标信噪比。
还需要说明的是， 402和 403之间的歩骤关系， 即 RNC获取第一功控参 考值和获取第二功控参考值， 是相对独立的过程， 可以不设定先后执行顺序 而独立执行。
还需要说明的是， 在本实施例中， 仅执行 402也可以获得目标功控值， 能够保证上行控制信道的信道质量； 可选的， 也可以进一歩获取上行数据信 道的信道质量达到目标门限时对应的第二功控参考值， 此时控制信道对应的 称为第一功控参考值。 但是即使获取了第二功控参考值， 也是选取能同时保 证上行数据信道和上行控制信道的信道质量的功控参考值作为目标功控值， 比如从第一目标信噪比和第二目标信噪比中选择较大者作为目标功控值。 在 本实施例以及后续的实施例中， 是均以获取第一目标信噪比和第二目标信噪 比两个值为例。
404、 RNC从所述第一功控参考值和第二功控参考值中选择其中之一作 为目标功控值；
405、 RNC将目标功控值分别发送至微站和宏站；
406、 微站根据目标功控值对 UE4进行功率控制。
其中， 宏站和微站都会根据目标功控值对其覆盖区域内的 UE进行功率 控制， 只是在切换区的 UE， 是由上行信号质量较好的微站对 UE4的上行发 射功率进行控制。由于该目标功控值即 SIR target相对于现有技术中微站用于 控制的 SIR target要高， 所以 UE4的上行发射功率也得到提高， 从而提升了 UE4向其服务基站宏站的上行控制信道质量， 避免了 UE4的失歩问题。 实施例四
图 5为本发明实施例提供的又一种终端控制方法的信令示意图， 本实施 例重点描述 RNC获取第一功控参考值的另一种方式， 其他歩骤简单描述， 具 体可以结合参见实施例一和实施例二。 本实施例与实施例三的区别在于， 实 施例三的第一功控参考值的获取是在 RNC, 而本实施例的第一功控参考值的 获取是在宏站， 由宏站发送给 RNC。 如图 5所示， 该方法可以包括：
501、 RNC确定与宏站和微站均建立连接的终端的下行服务基站为宏站； 本实施例中， RNC可以获知 UE4的下行服务基站是宏站，继续执行 502。
502、 宏站获取上行控制信道的信道测量指标值；
可选的， 所述的上行控制信道是 UE4向宏站的上行控制信道； 所述的信 道测量指标值例如是， TPC检测概率、 CQI检测概率、 Pilot BER或者 TFCI 漏检参考指示值等， 宏站在接收到 UE4发送的上行控制信息时， 是可以得到 上述的信道测量指标值的。
503、 宏站将与目标信道测量指标值对应的功控值作为第一功控参考值； 本歩骤的确定过程与实施例三中 RNC的处理过程类似，不再赘述。同样， 可选的， 也可以将该歩骤中的所述功控值称为第一功控参考值。
504、 宏站将所述第一功控参考值发送给所述 RNC;
可选的， 本歩骤中可以是宏站定期向 RNC上报第一功控参考值， 或者也 可以是， 宏站在接收到 RNC发送的请求指示时发送。
505、 RNC获取第二功控参考值；
其中， 本歩骤与 RNC获取第一功控参考值的过程， 可以是独立进行的。
506、 RNC从所述第一功控参考值和第二功控参考值中选择其中之一作 为目标功控值；
507、 RNC将目标功控值分别发送至微站和宏站；
508、 微站根据目标功控值对 UE4进行功率控制。
实施例五
在按照前述各实施例的终端控制方法对 UE4进行功率控制后， UE4的上 行发射功率相比原来有所提高； 其他区域用户可以使用上行服务链路进行外 环功控。
此外， 在 Hetnet同频组网典型场景下， 还存在如下的干扰问题： 一般宏 小区的最大发射功率为 20w， 而微小区的最大发射功率为 5w或者 lw， 此时 宏微小区下行导频发射功率相差 6dB或 13dB， 导致存在以下两个问题区域： 一个是 Non-SHO区域， UE离微小区的距离小于离宏小区的距离， 最优小区 为宏小区且不存在微小区链路， 由于该区域内的 UE离微小区更近， 所以其 对微小区的干扰也较强； 另一个是 SHO区域， 最优小区为宏小区且存在微小 区链路， 当用户进入宏微软切换区之后， 宏微小区都会对用户的上行链路进 行内环功率控制， 由于微小区接收到的上行专用物理控制信道 （Dedicated Physical Control Channel, 简称： DPCCH ) SIR会比宏小区高， 此时微小区 的内环功控将会起主导作用， 导致宏小区 DPCCH SIR明显较差，使得服务宏 小区 HSDPA/HSUPA吞吐率受影响。 并且， 可选的， 宏站和微站在对自身覆 盖区域内的其他 UE进行功率控制时， 也可以根据本发明实施例确定的目标 功控值， 这将使得其他 UE的上行发射功率有所提高， 这可能在一定程度上 出现 UE之间的上行信号干扰。
例如， 参见图 1， 对于图 1中的 UE2, 其位于上行边界靠近宏站的一侧， 虽然此时 UE2的上下行最优链路均是宏站， 但是由于其靠近上行边界， 对微 站的上行链路仍然会有较强的干扰， 所以本实施例将以微站为例， 说明微站 如何消除邻区 UE的上行信号干扰， 比如对于 UE2和 UE3均适用， UE2和 UE3将对 UE5造成干扰。 具体的， 微站可以接收 RNC发送的微站邻区中的 至少一个终端的用户信息， 并根据该用户信息将所述终端的目标干扰上行信 号， 从微站接收的终端上行信号中消除。 具体接收何种用户信息以及如何根 据用户信息进行干扰消除， 下面将通过几个实施例详细描述：
图 6为本发明实施例提供的又一种终端控制方法的信令示意图， 该方法 主要是对上述的干扰消除过程进行说明， 具体实施中， 干扰消除可以是在上 面所述的 UE功率控制之后进行， 比如微站在对 UE4进行功率控制之后， 再 接收到 UE4的上行信号时可以按照本实施例的方法对 UE4的信号进行干扰消 除。 本实施例以微站的干扰消除执行过程为例， 当然可选的， 宏站也可以按 照该方法执行； 如图 6所示， 该方法可以包括：
601、微站接收 RNC发送的微站邻区中的至少一个终端的上行扰码信息、 以及终端在微站邻区的上行控制信道参数信息；
其中， 各 UE的上行扰码信息是由 RNC分配的， 所以 RNC是能够知道 UE的上行扰码信息的。 微站可以从 RNC获取微站的相邻小区中的各 UE的 上行扰码信息， 所述的微站邻区可能有多个， 以图 1为例， 微站邻区即是宏 站所在的小区； 所述的至少一个终端可以是所有的微站邻区中的各个终端， 当然其中包括对微站干扰较强的 UE、 以及干扰较弱的 UE， 在本歩骤中， 可 以不进行干扰程度的区分， 而是获取所有邻区 UE的上行扰码信息， 由微站 在本实施例的后续歩骤进行处理。
此外， 微站还可以接收相邻小区的基站发送的上行控制信道参数信息， 比如， 相邻小区内可能有多个 UE， 可以称为多个邻区终端， 那么本实施例获 取的是各邻区终端在所属的邻区基站的上行控制信道参数信息， 例如， 图 1 中的 UE1向宏站的上行控制信道参数信息、 UE2向宏站的上行控制信道参数 信息、 UE3向宏站的上行控制信道参数信息等， 是分别与 UE对应的。 该上 行控制信道参数信息例如包括 UE的扩频因子 （spreading factor, 简称： SF) 等； 所述的上行控制信道参数信息可以用于对 UE的上行信号进行解调。
602、 微站根据上行扰码信息获取 UE的上行信号， 并根据信号强度选取 强干扰的邻区干扰 UE， 得到邻区干扰终端对应的上行信号；
其中， 微站在 601中接收到 RNC发送的各邻区 UE的上行扰码信息后， 该上行扰码信息可以用于识别 UE,微站可以据此获取各邻区 UE的上行信号， 并得到邻区 UE的上行信号接收强度； 例如， 可以通过小区盲搜索或者检测 算法获得邻区 UE的上行信号接收强度。微站根据邻区 UE的上行信号接收强 度进行 UE排序，选取对微站造成强干扰的 UE,称为邻区干扰终端。显然的， 该邻区干扰终端的上行扰码信息已经在 601中由 RNC发送给微站，该邻区干 扰终端与所属的邻区基站的上行控制信道参数信息也已经在 601中由邻区基 站发送给微站， 只是在本歩骤中才由微站从各邻区 UE中区分得到。
微站将得到的邻区干扰终端加入本小区解调用户级， 即需要对邻区干扰 终端的上行信号进行解调并进行后续的干扰消除。 举例如下： 微站既接收到 本小区内的 UE5的上行信号，也接收到非本小区的 UE3的上行信号，并且微 站已经判断得到 UE3的上行信号接收强度较高， 为强干扰用户 （称为干扰终 端），微站可以根据 UE3的上行扰码信息将 UE3的上行信号从接收到的终端 上行信号中选取出来。 当然， 将干扰比较强的邻区干扰终端的信号选取出来 继续干扰消除是可选的， 干扰较弱的其他终端也可以进行干扰消除， 多种可 能的实施方式不再列举， 以下的各实施例均是以消除邻区干扰终端的信号为 例进行说明。
603、微站利用上行控制信道参数信息对上行信号进行解调， 得到译码软 值或者译码硬值；
其中， 微站在将 UE3的上行信号从接收到的各上行信号中识别出来后， 就可以利用从宏站接收到的与 UE3对应的上行控制信道参数信息例如 SF,对 该 UE3的上行信号解调得到译码值，该译码值可以是译码软值或者译码硬值。
604、 微站使用解调译码得到的译码值得到目标干扰上行信号；
在 603中得到的译码软值或者译码硬值是用于重构信号的，可以得到 UE3 的上行信号， 本次得到的 UE3的上行信号是真正的干扰信号， 可以称为目标 干扰上行信号。
605、 微站将目标干扰上行信号从接收的终端上行信号中消除。
在本歩骤中， 微站将 UE3的上行信号消除， 即消除了 UE3对 UE5的信 号干扰。
本实施例通过将邻区干扰终端的目标干扰上行信号， 从基站接收的终端 上行信号中消除， 从而消除了邻区干扰终端的干扰， 提高了基站接收的上行 信号的质量。
实施例六
图 7为本发明实施例提供的又一种终端控制方法的信令示意图， 该方法 也是对干扰消除过程进行说明， 比如微站要将 UE3的上行信号消除； 本实施 例与实施例五的区别在于， 实施例五中宏站将控制信道参数发送给微站， 由 微站根据该参数解调接收信号得到译码值， 而本实施例中宏站是直接将译码 值发送给微站， 微站直接进行信号重构。 如图 7所示， 该方法可以包括：
701、微站接收 RNC发送的微站邻区中的至少一个终端的上行扰码信息； 其中， RNC可以将微站相邻小区的各 UE的上行扰码信息都上报至微站。
702、 微站根据上行扰码信息获取 UE的上行信号， 并根据信号强度选取 强干扰的邻区干扰 UE， 得到邻区干扰终端对应的上行信号；
例如， 微站获取到 UE3的上行信号。
703、 微站请求邻区基站发送邻区干扰终端对应的译码值；
本实施例中， 微站在判断得到 UE3是邻区干扰终端后， 可以指示宏站发 送 UE3对应的译码值， 以用该译码值进行 UE3的信号重构。在发送上述指示 时，微站可以同时将 UE3对应的上行扰码信息或者其他 UE标识发送给宏站， 以使得宏站能够获知要得到的是 UE3的译码值。
可选的， 译码值也可以是宏站定期上报给微站。
704、微站接收邻区基站发送的译码值、 以及邻区干扰终端的上行控制信 道参数信息；
705、微站根据所述上行控制信道参数信息对邻区干扰终端的上行信道信 息进行估计；
706、微站使用译码值、以及上行信道信息，重构得到目标干扰上行信号; 707、 微站将目标干扰上行信号从接收的终端上行信号中消除。

例如， 微站获取到 UE3的上行信号。
803、 微站请求邻区基站发送邻区干扰终端对应的译码值；
本实施例中， 微站在判断得到 UE3是邻区干扰终端后， 可以指示宏站发 送 UE3对应的译码值， 以用该译码值进行 UE3的信号重构。在发送上述指示 时，微站可以同时将 UE3对应的上行扰码信息或者其他 UE标识发送给宏站， 以使得宏站能够获知要得到的是 UE3的译码值。
可选的， 译码值也可以是宏站定期上报给微站。
804、邻区基站获取邻区干扰终端的上行控制信道参数信息， 并利用该参 数信息对邻区干扰终端的上行信号进行解调得到第一译码值；
本实施例中， 宏站获取 UE3对应的上行控制信道参数信息， 并利用该参 数信息对 UE3的上行信号进行解调得到译码值， 例如可以是译码软值或译码 硬值， 该上行信号可以是 UE3上行发送给宏站的信号。 其中， 为了与后续歩 骤的另一译码值进行区分， 将本歩骤中宏站得到的译码值称为第一译码值。
805、微站接收邻区基站发送的第一译码值、 以及邻区干扰终端对应的上 行控制信道参数信息；
本实施例中， 宏站会将 804中得到的第一译码值、 以及 UE3与宏站上行 的上行控制信道参数信息， 一并发送给微站。
806、微站使用上行控制信道参数信息对上行信号进行解调， 得到第二译 码值；
其中， 微站在将 UE3的上行信号从接收到的各上行信号中识别出来后， 就可以利用从宏站接收到的与 UE3对应的上行控制信道参数信息例如 SF,对 该 UE3的上行信号解调得到第二译码值。
807、 微站结合第一译码值和第二译码值重构得到目标干扰上行信号；
808、 微站将目标干扰上行信号从接收的终端上行信号中消除。
此外， 对于图 1中切换区内的 UE4和 UE5 , 宏站和微站可以都适用 IC 进行干扰消除， 或者， 宏站和微站对于本小区非切换区内的 UE, 可以利用干 扰去除 （Interference cancellation, 简称： IC) 与干扰抑制合并 （Interference rejection combining, 简称： IRC) 进行干扰消除。
需要说明的是， 本实施例并不严格限制各歩骤的执行顺序； 另外， 本实 施例的干扰消除方案是以微站为例， 其也可以应用于宏站， 例如宏站可以利 用本方法将 UE5的信号作为干扰信号进行消除。 可选的， 上述实施例五至实 施例七中的干扰消除方案， 也可以是单独实施在异构网中而不限制在终端功 率控制之后执行。
