Method for transmitting enhanced control channel in a wireless communication system and apparatus therefor
First Claim
1. A method for transmitting an enhanced a physical downlink control channel (EPDCCH) by a serving cell in a wireless communication system, the method comprising the steps of:
- configuring a plurality of enhanced resource element groups (EREGs) by dividing available resource elements, which are included in one physical resource block (PRB) pair, into a predetermined number;
configuring an enhanced control channel element (ECCE), which is a resource allocation unit for the EPDCCH, by selecting one or more EREGs from the plurality of EREGs; and
transmitting the EPDCCH by using transmission resources allocated for the EPDCCH in a unit of the ECCE,wherein one or more EREGs constituting the ECCE are selected on the basis of at least one of cell ID of the serving cell and index of the one PRB pair.

Abstract
The present invention relates to a method for transmitting a downlink control channel in a wireless communication system, and an apparatus therefor. Specifically, the method for transmitting an enhanced a physical downlink control channel (EPDCCH) from a serving cell comprises the steps of: forming a plurality of enhanced resource element groups (EREGs) by dividing available resource elements, comprised in one physical resource block (PRB) pair, into a predetermined number; forming an enhanced control channel element (ECCE), which is a resource allocation unit for the EPDCCH, by selecting one or more EREGs from among the plurality of EREGs; and transmitting the EPDCCH by means of the transmission resource allocated, for each ECCE, for the EPDCCH, wherein one or more EREGs forming the ECCE is selected on the basis of a cell identifier of the serving cell and/or an index of the one PRB pair.

6. A serving cell for transmitting an enhanced physical downlink control channel (EPDCCH) in a wireless communication system, the serving cell comprising:
-
a radio frequency (RF) unit; and a processor, wherein the processor configures a plurality of enhanced resource element groups (EREGs) by dividing available resource elements, which are included in one physical resource block (PRB) pair, into a predetermined number, and configures an enhanced control channel element (ECCE), which is a resource allocation unit for the EPDCCH, by selecting one or more EREGs from the plurality of EREGs, the RF unit is configured to transmit the EPDCCH by using transmission resources allocated for the EPDCCH in a unit of the ECCE, and one or more EREGs constituting the ECCE are selected on the basis of at least one of cell ID of the serving cell and index of the one PRB pair. - View Dependent Claims (7, 8, 9, 10)
