US 2015/0092690 A1 · METHOD FOR SETTING SEARCH REGION FOR 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. In detail, the method includes the step of: receiving the EPDCCH by monitoring EPDCCH candidates consisting of one or more enhanced control channel elements (ECCEs) in at least one resource block set for EPDCCH, wherein the number of ECCEs forming each of the EPDCCH candidates corresponds to an aggregation level, and the period between the EPDCCH candidates for one carrier, which is a specific aggregation level, is determined by dividing the total number of ECCEs included in each of the one or more resource blocks by a corresponding aggregation level and the number of the EPDCCH candidates which are the specific aggregation level.

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:

receiving the EPDCCH by monitoring EPDCCH candidates in at least one resource block set for the EPDCCH,
wherein a number of ECCEs (Enhanced Control Channel Elements) included in each of the EPDCCH candidates is an aggregation level,
wherein an interval between each of the EPDCCH candidates for one carrier at a specific aggregation level is determined based on a value of a total number of ECCEs included in the at least one resource block set divided by the specific aggregation level and a number of the EPDCCH candidates at the specific aggregation level.

Dependencies are inferred from the claim text.
