ROTATION PRE-CODER BASED SELF-INTERFERENCE CANCELLATION METHOD AND APPARATUS IN WIRELESS ACCESS SYSTEM SUPPORTING FULL DUPLEX RADIO SCHEME |
摘要 |
The present invention provides methods for cancelling a rotation pre-coder based self-interference in FDR system and apparatuses supporting the same. A method for cancelling a rotation pre-coder based self-interference by a terminal in a wireless access system supporting a full-duplex radio (FDR) scheme, as an embodiment of the present invention, may comprise the steps of: receiving a first reference signal from a base station; receiving, by a terminal, a second reference signal transmitted from the terminal; estimating a preferred channel on the basis of the first reference signal and a self-interference channel on the basis of the second reference signal; measuring a rotation angle on the basis of a first angle which is perpendicular to a detection axis with respect to the preferred channel and a second angle with respect to the interference channel; rotating the self-interference channel using a rotation angle; and cancelling an interference signal on the basis of the rotated self-interference channel. In this case, the first angle and the second angle may be a value measured from 0 degrees of real-number axis. |
