METHOD AND APPARATUS FOR TRANSMITTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM Russian patent published in 2016 - IPC H04W24/10 

FIELD: communication.

SUBSTANCE: invention relates to wireless communication. Transmitting channel state information (CSI) by user equipment in wireless communication system includes receiving channel state information reference signal (CSI-RS), determining overhead costs of the resource element of the common reference signal (CRS) based on the number of antenna ports, that is equal to number of antenna ports associated with a reference signal CSI-RS, and transmitting channel state information (CSI), calculated based on the CSI-RS and overhead costs of the resource element of the reference signal CRS.

EFFECT: technical result is efficient calculating channel quality indicator.
