Abstract: Disclosed are methods for transmission and reception of downlink control information between a base station and a terminal, and devices for supporting same. Disclosed more particularly are: methods whereby a base station transmits downlink control information by means of an analogue beam independently determined for every one or more symbols (e.g., a unit of one or more symbols) and, in response to the base station, a terminal receives, by means of a serving beam of the terminal, the downlink control information transmitted by means of the analogue beam, which corresponds to the serving beam; and devices for supporting same.

Abstract: A method is provided for receiving a downlink signal through an Enhanced Physical Downlink Control Channel (EPDCCH) in a wireless communication system by a user equipment (UE). The UE receives a parameter indicating a quasi co-location behavior type is. The UE further receives a demodulation reference signal (DMRS) associated with the EPDCCH. The UE attempts to decode the EPDCCH based on the DMRS. If a transmission mode configured in the UE is a transmission mode 10, the UE assumes that antenna ports of the DMRS are quasi co-located with antenna ports of a reference signal determined by the parameter.
