US 2015/0029963 A1 · METHOD AND DEVICE FOR TRANSMITTING A TERMINAL-SPECIFIC REFERENCE SIGNAL FOR A CONTROL CHANNEL BY A BASE STATION IN A WIRELESS COMMUNICATION SYSTEM

Abstract

The present invention relates to a method for transmitting a terminal-specific reference signal for a control signal by a base station in a wireless communication system. Specifically, the method is characterized in that it comprises: transmitting a plurality of control channels and a first terminal-specific reference signal for the plurality of control channels to a first resource region; and transmitting one control channel and a second terminal-specific reference signal for the control channel to a second resource region, wherein the different descrambling identifiers are applied to the first and second terminal-specific reference signals.

A method for transmitting a user equipment (UE)-specific reference signal for a control channel by a base station (BS) in a wireless communication system, the method comprising:

transmitting a plurality of control channels and a first UE-specific reference signal for the plural control channels to a first resource region;
and
transmitting one control channel and a second UE-specific reference signal for the one control channel to a first resource region,
wherein different scrambling identifiers are applied to the first UE-specific reference signal and the second UE-specific reference signal.
