A user equipment (UE) measures a first type CSI for a first component carrier (CC) of two or more downlink (DL) CCs, and measures a second type CSI for a second CC of the two or more DL CCs. The UE reports the first type CSI only, when a collision of a report of the first type CSI with a report of the second CSI type occurs in a same subframe. The first type CSI includes (1) only a Wideband Channel Quality Indicator (WB-CQI), (2) the WB-CQI and a first Precoding Matrix Indicator (PMI) or (3) the WB-CQI and a second PMI. The second type CSI includes (1) only a SubBand (SB) CQI or (2) the SB-CQI and a SB second PMI."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for transmitting channel state information in wireless access system","description":"A method is provided for reporting Channel State Information (CSI) in a wireless access system which supports carrier aggregation.
