A user equipment (UE) transmits first channel information indicating a set of precoding matrices to a base station (BS) periodically, and transmits second channel information indicating one precoding matrix included in the set of precoding matrices to the BS periodically. The second channel information transmitted in a specific subframe is determined based on first channel information that has most recently been transmitted before the specific subframe. Additionally, the UE calculates a channel quality indicator (CQI) transmitted in the specific subframe based on one precoding matrix specified by the first channel information that has most recently been transmitted before the specific subframe and by the second channel information determined based on the first channel information that has most recently been transmitted before the specific subframe."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting channel state information","description":"A method for transmitting channel status information in a wireless communication system.
