Abstract
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.
Claims10
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.
A method for receiving, by a UE, an EPDCCH from a base station 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 for each of the re-indexed resource blocks;
- and
- monitoring EPDCCH candidates composed of ECCEs in a number corresponding to an aggregation level of the EPDCCH, in the re-indexed resource blocks, to receive the EPDCCH.
