US 2015/0085773 A1 · METHOD FOR FORMING RESOURCE BLOCK FOR SEARCH REGION IN DOWNLINK CONTROL CHANNEL IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR

Abstract

The present invention relates to a method for a terminal to receive an enhanced physical downlink control channel (EPDCCH) from a based 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 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.

Dependent claims

A method for receiving an EPDCCH (Enhanced Physical Downlink Control Channel) from a base station by a user equipment (UE) in a wireless communication system, the method comprising:

defining a first number of EREGs (Enhanced Resource Element Groups) in each of resource blocks for the EPDCCH;
and
receiving the EPDCCH by monitoring EPDCCH candidates comprising one or more ECCEs (Enhanced Control Channel Elements) in the resource blocks,
wherein each of the one or more ECCEs comprises a second number of EREGs,
wherein indexes of the second number of EREGs are determined as intervals of a number of ECCEs per resource block.
