METHOD FOR TRANSMITTING DOWNLINK CONTROL CHANNEL BY BASE STATION IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR

摘要

Disclosed is a method for transmitting a downlink control channel by a base station in a wireless communication system. More particularly, the method comprises the following steps: setting a transmission resource for transmitting the downlink control channel in a data area of a subframe; mapping one or more first control channels for downlink acknowledgement(ACK)/negative-ACK(NACK) information to the transmission resource; and transmitting the mapped one or more first control channels, wherein the one or more first control channels are mapped to a location adjacent to a terminal specific reference signal existing in the transmission resource.

1. A method for transmitting a downlink control channel by a base station in a wireless communication system, the method comprising:
configuring transmission resources for the downlink control channel in a data region of a subframe; mapping one or more first control channels carrying downlink acknowledgment (ACK)/negative ACK (NACK) information to the transmission resources; and transmitting the mapped one or more first control channels, wherein the one or more first control channels are mapped to locations near a user equipment (UE)-specific reference signal (RS) which is present in the transmission resources.
