Abstract
A method of reporting channel state information (CSI) by a user equipment (UE) in a wireless communication system, includes receiving, from a base station (BS), first information on a set of CSI-reference signal resource element (CSI-RS RE) configurations and second information on a time resource configuration; obtaining CSI based on the first and the second information; and reporting, to the BS, the CSI, wherein the time resource configuration includes a CSI-RS periodicity commonly used for the CSI-RS RE configurations in the set.

A method of reporting channel state information (CSI) by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station (BS), first information on a set of CSI-reference signal resource element (CSI-RS RE) configurations and second information on a time resource configuration;
- obtaining CSI based on the first and the second information;
- and
- reporting, to the BS, the CSI,
- wherein the time resource configuration includes a CSI-RS periodicity commonly used for the CSI-RS RE configurations in the set.
A method of receiving channel state information (CSI) by a base station (BS) in a wireless communication system, the method comprising:
- transmitting, to a user equipment (UE), first information on a set of CSI-reference signal resource element (CSI-RS RE) configurations and second information on a time resource configuration;
- receiving, from the UE, CSI,
- wherein the time resource configuration includes a CSI-RS periodicity commonly used for the CSI-RS RE configurations in the set.
A user equipment (UE) for reporting channel state information (CSI) in a wireless communication system, the UE comprising:
- a transmission module;
- a reception module;
- and
- at least one processor for controlling the transmission module and the reception module,
- wherein the at least one processor is configured to:
- control the reception module to receive, from a base station (BS), first information on a set of CSI-reference signal resource element (CSI-RS RE) configurations and second information on a time resource configuration;
- obtain CSI based on the first and the second information;
- and
- control the transmission module to report, to the BS, the CSI,
- wherein the time resource configuration includes a CSI-RS periodicity commonly used for the CSI-RS RE configurations in the set.
A base station (BS) for receiving channel state information (CSI) in a wireless communication system, the BS comprising:
