According to one embodiment of the present invention, a method for estimating a self-interference (SI) channel, by a base station, in a wireless access system supporting wireless FDR communication comprises the steps of: transmitting a channel signal including a first cyclic shift variable allocated to a terminal; transmitting a downlink (DL) self-interference reference signal (SI-RS) for estimating the SI channel generated on the basis of a second cyclic shift variable; receiving the DL SI-RS; receiving an uplink (UL) SI-RS generated on the basis of the first cyclic shift variable; and estimating the SI channel using the DL SI-RS and the UL SI-RS."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for estimating self-interference in wireless access system supporting full-duplex radio communication","description":"The present invention provides methods for estimating self-interference in a full-duplex radio (FDR) system using a reference signal to which a cyclic shift is applied, and apparatuses supporting the ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9713143","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
