Method for forming resource block for search region in distribution-type downlink control channel in wireless communication system, and apparatus therefor

摘要

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; monitoring EPDCCH candidates consisting of one or more enhanced control channel elements (ECCEs) in resource blocks so as to receive the EPDCCH, wherein each of the one or more ECCEs consists of a second number of EREGs included in different resource blocks, and the indexes of the resource blocks including the second number of EREGs are determined on the basis of a specific value obtained by dividing the number of resource blocks by the second number.

1. A method for receiving an Enhanced Physical Downlink Control Channel (EPDCCH) from a base station by a user equipment (UE) in a wireless communication system, the method comprising:
defining, by the UE, a first number of Enhanced Resource Element Groups (EREGs) in a resource block pair for the EPDCCH; and receiving, by the UE from the base station, the EPDCCH by monitoring EPDCCH candidates comprising one or more Enhanced Control Channel Elements (ECCEs) in the resource block pair, wherein each of the one or more ECCEs comprises a second number of EREGs included in different resource blocks, and wherein indexes of the second number of EREGs form an ECCE with an index n determined by Expression A,
└n/NRBSm┘+jNRBECCE   where NRBECCE indicates a number of ECCEs per resource block pair, j=0, 1, . . . NECCEEREG−1, NECCEEREG indicates the second number of EREGs, and NRBSm indicates a number of resource block pairs.
