串扰信道估计的方法、矢量化控制实体VCE和接入节点AN技术

本发明专利技术公开了一种串扰信道估计的方法、矢量化控制实体VCE和接入节点AN。该方法包括：向接入节点AN发送切换消息，该切换消息包括第一导频信号PS的信息和第一指示信息；接收该AN发送的切换响应消息，该切换响应消息包括该第一索引值和第二索引值；接收CPE发送的测量信息，该测量信息包括该CPE根据该AN发送的PS得到的测量结果和该测量结果对应的该PS的第三索引值；根据该第一索引值、该第二索引值和该第三索引值确定第四索引值；根据该第四索引值和该测量结果进行串扰信道估计。本发明专利技术实施例的串扰信道估计的方法，能够实现指定长度导频信号PS的发送，节省CPE升级的成本，减少PS的发送时间。

Crosstalk channel estimation method, vectored control entity VCE and access node AN

The invention discloses a crosstalk channel estimation method, a vector control entity VCE and an access node AN. The method includes: sending a switching message to the access node AN, which includes information and first indication information of the first pilot signal PS, and receiving the switching response message sent by the AN, which includes the first index value and the second index value, and receives the measurement information sent by the CPE, which includes the CPE. The third index value of the PS corresponding to the measured result of the PS transmitted by the AN is corresponding to the result of the measurement; the fourth index value is determined according to the first index value, the second index value and the third index value; the crosstalk channel estimation is carried out according to the fourth index value and the measurement result. The method of crosstalk channel estimation in the embodiment of the invention can realize the transmission of the specified length pilot signal PS, save the cost of the CPE upgrade and reduce the sending time of the PS.
