异构网络的不平衡区域的软切换区的信号发送方法及装置 技术领域
本发明涉及通信技术领域, 尤其涉及异构网络的不平衡区域的软切换区 的信号发送方法及装置。 背景技术
为了增强网络的处理能力, 现有技术提供了一种异构网络 (Hetnet , Heterogeneous network )技术。 异构网络通常包括宏基站和微基站。 若位于异 构网络中的用户设备 (User Equipment, UE)的发射信号在宏基站和微基站处有 相同的信号强度, 则用户设备在异构网络中的位置被称为上行平衡点。 若宏 基站和微基站发射的信号在用户设备处有相同的信号强度, 则用户设备在异 构网络中的位置被称为下行平衡点。 上行平衡点和下行平衡点之间的区域称 为不平衡区域。
当用户设备处于不平衡区域的软切换区域时, 发明人发现, 现有技术存 在如下问题: 当宏基站接收不到上行服务请求信息时, 上行服务不稳定; 当 宏基站接收不到下行数据的反馈信息时, 下行服务不稳定。 同时由于在用户 设备所处的切换区域中, 微基站发送的第一功率控制命令在用户设备处没有 稳定的接收, 会导致微基站无法有效抑制用户设备的发射功率, 给微基站带 来上行干扰。 发明内容
