METHOD FOR SEARCHING CONTROL SIGNALS IN A WIRELESS ACCESS SYSTEM SUPPORTING CARRIER AGGREGATION (CA)

摘要

The present invention relates to a wireless access system supporting carrier aggregation and carrier aggregation technology, and discloses methods for effectively searching control signals for a plurality of cells and apparatuses supporting same. In an embodiment of the present invention, a method for searching control signals in a wireless access system supporting multiple carrier aggregation (CA) and cross carrier scheduling may comprise the steps of: calculating the start point of a reference search space in an expanded search space; calculating start points of the next search spaces which are spaced apart from the reference search space by a predetermined offset value; and performing blind decoding on the reference search space and subsequent search spaces to search control signals from a base station.
