Title:
METHOD FOR FORMING RESOURCE BLOCK FOR SEARCH REGION IN DOWNLINK CONTROL CHANNEL IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2013/151302
Kind Code:
A1
Abstract:
The present invention relates to a method for a terminal to receive an enhanced physical downlink control channel (EPDCCH) from a base station in a wireless communication system. More particularly, the method includes the steps of defining a first number of enhanced resource element groups (EREGs) for each resource block for the EPDCCH, and monitoring EPDCCH candidates consisting of one or more enhanced control channel elements (ECCEs) in the resource blocks and receiving the EPDCCH, wherein each of the one or more ECCEs consists of a second number of EREGs, and indexes of the second number of EREGs are determined to be intervals of the number of ECCEs for each resource block.
