1. A method performed by a user equipment (UE) in a communication system, the method comprising:
receiving, from a base station via higher layer signaling, one or more configurations associated with an aperiodic channel state information (CSI) report;
receiving, from the base station, downlink control information (DCI) including a CSI request field indicating a configuration among the one or more configurations; and
transmitting, to the base station, the aperiodic CSI report based on the configuration,
wherein, 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, the CSI request field indicates the configuration from at least one configuration selected via the MAC CE, and
wherein a number of the one or more configurations and a size of the CSI request field are considered to determine whether the MAC CE is used to map the configuration to the value of the CSI request field.
