Abstract
The present specification provides a method for reporting aperiodic channel state information (CSI) in a wireless communication system. Specifically, a method performed by the terminal comprises a step of receiving configuration information with respect to at least one reporting setting from a base station; a step of receiving control information indicating a measurement resource (MR) associated with the aperiodic CSI report from the base station; a step of computing aperiodic CSI on the basis of a particular reporting setting associated with the control information; and a step of transmitting the aperiodic CSI to the base station through a physical uplink control channel (PUCCH).
Claims12
A method of reporting aperiodic channel state information (CSI) in a wireless communication system, the method performed by a user equipment (UE), the method comprising:
- receiving, from a base station, configuration information for at least one reporting setting;
- receiving, from the base station, control information indicating a measurement resource (MR) related to the aperiodic CSI, the measurement resource including at least one of a channel measurement resource (CMR) or an interference measurement resource (IMR);
- computing the aperiodic CSI based on a specific reporting setting related to the control information;
- and
- transmitting, to the base station, the aperiodic CSI on a physical uplink control channel (PUCCH).
A UE reporting aperiodic channel state information (CSI) in a wireless communication system, the UE comprising:
- a radio frequency (RF) module for transceiving a radio signal;
- and
- a processor functionally connected with the RF module, wherein the processor is configured to:
- receive, from a base station, configuration information for at least one reporting setting;
- receive, from the base station, control information indicating a measurement resource (MR) related to the aperiodic CSI, the measurement resource including at least one of a channel measurement resource (CMR) or an interference measurement resource (IMR);
- compute the aperiodic CSI based on a specific reporting setting related to the control information;
- and
- transmit, to the base station, the aperiodic CSI on a physical uplink control channel (PUCCH).
A method of receiving an aperiodic channel state information (CSI) report in a wireless communication system, the method performed by a base station, the method comprising:
- transmitting, to a user equipment (UE), configuration information for at least one reporting setting;
- transmitting, to the UE, control information indicating a measurement resource (MR) related to the aperiodic CSI, the measurement resource including at least one of a channel measurement resource (CMR) or an interference measurement resource (IMR);
- and
- receiving, from the UE, the aperiodic CSI on a physical uplink control channel (PUCCH).
