Control signal search method in a wireless connection system that supports carrier aggregation (CA)

摘要

Relates to a radio access systems that support (Carrier Aggregation) Carrier Aggregation technology, the present invention provides an apparatus for supporting the same and method can search to effectively control signals for a plurality of cells. As one aspect of the present invention, how to find the control signal in a wireless access system supporting cross-carrier scheduling (CA) and multi-carrier aggregation, the method comprising: calculating the starting point of the reference search space in the search space is expanded, and to calculate the starting point of the search space to the next in a position with a predetermined offset value from the reference search space, to find the control signal from the base station by performing the blind decoding in the search space for the next reference and search space It is possible to include, and.
