干扰控制方法、 装置和系统 技术领域 本发明涉及通信技术, 尤其涉及一种干扰控制方法、 装置和系统。 背景技术
在宏蜂窝组网中, 处于边缘区域的用户和处于宏蜂窝热点话务区的用户 服务质量时常得不到保证。
现有技术通过在宏蜂窝的边缘区域及热点话务区设置微蜂窝的方式, 即 釆用异构组网 ( Heterogeneous network, 以下简称: Hetnet )方式来提高处于 这些区域的用户的服务质量。 然而, 由于微蜂窝基站的发射功率与宏蜂窝的 发射功率不一致, 因此, 上行功率平衡线与下行功率平衡线不同, 图 1为现 有技术中上下行功率平衡线的示意图, 如图 1所示, 上行功率平衡线 1分别 到宏蜂窝基站和微蜂窝基站的距离相等,下行功率平衡线 2靠近微蜂窝基站, 所谓上行功率平衡线是指 UE处于上行功率平衡线 1时以相同的功率向宏蜂 窝基站和微蜂窝基站发送信号, 宏蜂窝基站和微蜂窝基站接收到的信号功率 相同, 所谓下行平衡线是指宏蜂窝基站和微蜂窝基站以不同的功率向 UE发 送信号, UE在处于下行功率平衡线 2时, 接收到的信号功率相同, 软切换区 域指软切换边界线 3与软切换边界线 4之间的区域, 宏蜂窝基站和微蜂窝基 站都可以对处于软切换区域的 UE进行控制。
用户的服务小区是以下行功率平衡线来划分的, 因此当用户处于图 1 中 上行功率平衡线 i与软切换边界线 3之间的区域, UE的服务小区为宏蜂窝基 站, 但是处于这个区域的 UE的上行发送信号会对微蜂窝基站造成较大干扰。 发明内容 本发明实施例提供一种干扰控制方法、 装置和系统, 以减小处于特定区 域的 UE对微基站造成的干扰。
