Title:
METHOD AND DEVICE FOR SUPPRESSING INTERFERENCE SIGNAL
Document Type and Number:
WIPO Patent Application WO/2017/008520
Kind Code:
A1
Abstract:
A method and device for suppressing an interference signal, the method comprising: performing signal reduction on a received signal of a given cell; performing channel estimation on the signal-reduced received signal of the given cell on the basis of a reference signal of the given cell and a reference signal of a neighboring cell to obtain a precise interference signal; and performing signal suppression on the precise interference signal. In the present application, before acquiring an interference signal, signal reduction is first performed on a received signal of a given cell, and then using a signal obtained by performing the signal reduction on the received signal of the given cell, estimation of interference is performed on the basis of scheduling information of a joint neighboring cell to acquire an accurate interference signal, achieving improved suppression of neighboring cell uplink co-channel interference.
