Abstract: A method for receiving a feedback signal of a base station in a wireless communication system comprises the steps of: transmitting a data packet to a terminal; monitoring, during a preset monitoring interval, a first feedback signal representing whether the data packet has been successfully received or not; determining whether the first feedback signal monitored during the preset monitoring interval is an ACK signal or a NACK signal; and retransmitting the data packet to the terminal when the first feedback signal is determined to be the NACK signal. A first monitoring interval for monitoring the first feedback signal in order to determine the NACK signal may be set to be different from a second monitoring interval for monitoring the first feedback signal in order to determine the ACK signal.

Abstract: Disclosed is a method for a terminal reporting channel status information (CSI) to a base station in a wireless communication system. The method comprises receiving, via an upper later, information associated with a single CSI process comprising a firs enhanced multiple input multiple output (eMIMO) type and a second eMIMO type; reporting, to a base station, a first CSI updated on the basis of a first channel status information-reference signal (CSI-RS) corresponding to the first eMIMO type received from a first subframe; and receiving, from the base station, a triggering message of a second CSI calculated on the basis of a second CSI-RS corresponding to the second eMIMO type from a second subframe.
