METHOD FOR SETTING SEARCH REGIONS FOR DOWNLINK CONTROL CHANNELS IN WIRELESS COMMUNICATION SYSTEMS AND APPARATUS FOR SAME

摘要

The present invention relates to a method for transmitting an Enhanced Physical Downlink Control Channel (EPDCCH) from a based station to a terminal in a wireless communication system. In particular, the method includes the steps of: setting resource blocks for the EPDCCH; re-indexing by permutation indexes of the resource blocks; defining an Enhanced Control Channel Element (ECCE) for each of the re-indexed resource blocks; selecting the ECCEs in a number corresponding to the aggregation level of the EPDCCH; and transmitting the EPDCCH to the terminal using the selected ECCEs.

1. A method for transmitting, by a base station, an EPDCCH (Enhanced Physical Downlink Control Channel) to a user equipment (UE) in a wireless communication system, the method comprising:
setting resource blocks for the EPDCCH; re-indexing indexes of the resource blocks through permutation; defining an ECCE (Enhanced Control Channel Element) for each of the re-indexed resource blocks; selecting ECCEs in a number corresponding to an aggregation level of the EPDCCH; and transmitting the EPDCCH to the UE using the selected ECCEs.
