Abstract: A communication method for a channel access in a wireless communication system and an apparatus therefor are provided. The communication method includes an evolved NodeB (eNB) that transmits data to a user equipment (UE) through a licensed band, and determines whether an unlicensed band channel is in an idle state during a first channel sensing duration. If the unlicensed band channel is in the idle state, the eNB transmits data to the UE through an unlicensed band during a first channel occupying duration, a second channel sensing duration, and a second channel occupying duration. In the method, a sum of the first channel occupying duration, the second channel sensing duration, and the second channel occupying duration is equal to or less than a certain time.

Abstract: Methods and apparatuses in a communication system is provided. One or more configurations associated with an aperiodic channel state information (CSI) report are received from a base station via higher layer signaling. Downlink control information (DCI) including a CSI request field indicating a configuration among the one or more configurations is received from the base station. The aperiodic CSI report is transmitted to the base station based on the configuration. In case that a medium access control (MAC) control element (CE) is used to map the configuration to a value of the CSI request field based on a number of the one or more configurations and a size of the CSI request field, the CSI request field indicates the configuration from at least one configuration selected via the MAC CE.
