METHOD AND APPARATUS FOR TRANSMITTING RECEPTION ACKNOWLEDGEMENT IN WIRELESS COMMUNICATION SYSTEM

摘要

One embodiment of the present invention is a method in which a terminal transmits an acknowledgement of reception performed through an enhanced physical downlink control channel (EPDCCH) in a wireless communication system, the method comprising the steps of: decoding the EPDCCH in both a first EPDCCH physical resource block (PRB) set and a second EPDCCH PRB set; and transmitting an acknowledgement of reception performed through each EPDCCH. The resource indices for transmitting an acknowledgement of reception performed through each EPDCCH are determined in mutually different manner based on the type of the EPDCCH PRB set, whether or not the number of the PRB pairs contained in each EPDCCH PRB set corresponds to each other, and/or whether or not the EPDCCH PRB sets overlap.

主权项

1. A method for transmitting reception acknowledgement for an enhanced physical downlink control channel (EPDCCH) by a user equipment (UE) in a wireless communication system, comprising:
decoding an EPDCCH in each of a first EPDCCH Physical Resource Block (PRB) set and a second EPDCCH PRB set; and transmitting reception acknowledgement for each of the EPDCCHs, wherein a resource index for transmitting the reception acknowledgement for each of the EPDCCHs is differently determined depending on at least one of a type of each of the EPDCCH PRB sets, whether or not the EPDCCH PRB sets include the same number of PRB pairs, and whether or not the EPDCCH PRB sets overlap each other.
