CROSSTALK CHANNEL ESTIMATION METHOD, VECTORING CONTROL ENTITY (VCE) AND ACCESS NODE (AN)

摘要

Provided are a crosstalk channel estimation method, a vectoring control entity (VCE) and an access node (AN) The method comprises: sending a switching message to an access node (AN), wherein the switching message comprises information about a first pilot signal (PS) and first indication information; receiving a switching response message sent by the AN, wherein the switching response message comprises a first index value and a second index value; receiving measurement information sent by a CPE, wherein the measurement information comprises a measurement result obtained by the CPE according to the PS sent by the AN and a third index value of the PS corresponding to the measurement resu determining a fourth index value according to the first index value, the second index value and the third index value; and performing crosstalk channel estimation according to the fourth index value and the measurement result. By means of the crosstalk channel estimation method in the embodiments of the present invention, a pilot signal (PS) of a designated length can be sent, the cost for upgrading a CPE can be saved, and a sending time of the PS can be reduced.
