Description

发送附加导频信道信息的装置和方法
技术领域
本发明实施例涉及通信技术领域, 尤其涉及一种发送附加导频信道信 息的装置和方法。 背景技术
目前, 在宏基站和小基站共存的场景中, 为了增加小区的吞吐量, 在 宏基站覆盖的地方, 同时布置小基站, 图 1为现有的一种布网的示意图, 如图 1所示, 布网的方式是: 宏基站的小区和小基站的小区具有同频同小 区标识 (id) , 因此在逻辑上具有同频同小区标识的这两个小区就是一个 小区。 同时在这个逻辑小区内, 宏基站和小基站发送相同的公共导频信道
( Common Pilot Channel, 以下简称: CPICH) 。 其中 CPICH的作用是让用 户设备 (User Equipment, 以下简称: UE) 根据接收到 CPICH进行小区的 信道估计, UE进行正确的信道估计后才能正确接收数据和解调。小区标识 是用来对信号加扰的扰码, 加扰的目的是使用户能够区分不同小区不同信 道的数据信号。
在上述布网的方式中, 宏基站和小基站共同覆盖了一部分区域, 两个 小区的基站发送相同的公共导频信道, 并且使用相同的扰码,从而使得 UE 区分不出两个小区的信号,就会造成干扰, 因此会导致 UE无法正确接收数 据和解调。
