METHOD FOR SEARCHING FOR ENHANCED PDCCH AREA

摘要

The present invention relates to a method for searching for an enhanced physical downlink control channel (E-PDCCH), and devices supporting same. The method for searching for an E-PDCCH in a wireless access system, in one embodiment of the present invention, comprises the steps of: blind decoding a control channel area and searching for a legacy PDCCH; obtaining allocation location information of the E-PDCCH using one or more of initiation location information, completion location information, and size information on the allocation area of the legacy PDCCH; and searching for the E-PDCCH using the allocation location information of the E-PDCCH, wherein the E-PDCCH being allocated to a data channel area is more desirable than being allocated to the control channel area.

主权项

1. A method for searching for an Enhanced Physical Downlink Control Channel (E-PDCCH) in a wireless access system, the method comprising;
searching for a legacy Physical Downlink Control Channel (PDCCH) by blind-decoding a control channel region; acquiring allocation location information for the E-PDCCH based on information about at least one of a starting position, an ending position, and a size of an allocation region of the legacy PDCCH; and decoding the E-PDCCH based on the allocation location information for the E-PDCCH, wherein the E-PDCCH is allocated not to the control channel region but to a data channel region.
