Abstract: A method of performing channel access on an unlicensed band by a user equipment in a wireless communication system, includes sensing a carrier of an unlicensed band for receiving a downlink signal; and receiving the downlink signal when power detected by sensing the carrier is less than an energy detection threshold that is configured by a base station, wherein the energy detection threshold is configured to be equal to or less than a maximum energy detection threshold determined by the base station, and wherein when a different radio access technology (RAT) sharing the carrier is able to exist, the maximum energy detection threshold is determined adaptively to a bandwidth of the carrier using a decibel value of a ratio between a reference bandwidth and the bandwidth of the carrier.

Abstract: Provided is a communication method for interference avoidance in an unlicensed band. A transmission node transmits in the unlicensed band a preemption signal to a target reception node. Upon receiving a ready signal from the target reception node, the transmission node transmits in the unlicensed band a data signal to the target reception node. The preemption signal is transmitted by means of a narrow beam having substantially the same width and direction as the data signal.

Abstract: Disclosed is a method by which a terminal reports channel status information to a base station in a wireless communication system. Particularly, the method comprises the steps for attempting to detect a reference signal repeatedly transmitted multiple times for each reference signal transmission unit; setting the reference signal transmission unit as an effective reference resource for the channel state information when the reference signal is detected in a preset section within the reference signal transmission unit; measuring the channel state information at the effective reference resource; and reporting the channel state information to the base station.
