Method for reporting channel state information in wireless communication system and apparatus for the same

A user equipment (UE) configured to report channel state information (CSI) in a wireless communication system, the UE comprising:

• a radio frequency (RF) module;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
• receiving, from a base station, a plurality of lists of first values representing time offsets for transmitting a CSI report;
• receiving, from the base station, an index value related to a time at which to transmit the CSI report on a physical uplink shared channel (PUSCH);
• determining a plurality of list entries by determining, for each list in the plurality of lists of first values, a corresponding list entry that is indexed in the list based on the index value;
• determining a second value that is largest among the plurality of list entries;
• and
• transmitting, to the base station, the CSI report on the PUSCH based on the second value.

A method of receiving, by a base station (BS), channel state information (CSI) in a wireless communication system, the method comprising:

• transmitting, to a user equipment (UE), a plurality of lists of first values representing time offsets for transmitting a CSI report;
• transmitting, to the UE, an index value related to a time at which to transmit, by the UE, the CSI report on a physical uplink shared channel, PUSCH,
• wherein corresponding list entries in each list of the plurality of lists of first values are determined based on the index value;
• and
• receiving, from the UE, the CSI report on the PUSCH based on a second value,
• wherein the second value is the largest among the corresponding list entries.
