METHOD AND APPARATUS FOR TRANSMITTING APERIODIC CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

Provided are a method for transmitting the aperiodic channel state information of a terminal and the terminal using the same. The method includes the steps of: receiving a channel state information request about a plurality of reference signals; receiving the reference signals; generating channel state information about each reference signal according to the channel state information request; and transmitting the channel state information through a physical uplink shared channel (PUSCH). The channel state information request is included in a part of subframes which receive the reference signals.
