Method for transmitting channel state information in wireless access system |
摘要 |
Channel State Information (CSI) is reported by a user equipment (UE) in a wireless access system which supports carrier aggregation. A first type CSI for a first component carrier (CC) of two or more downlink (DL) CCs is measured. A second type CSI for a second CC of the two or more downlink (DL) CCs is measured. The first type CSI only is reported, when a collision of a report of the first type CSI with a report of the second CSI type is occurred in a same subframe. In addition, the first type CSI includes (1) a Rank indicator (RI) and a first Precoding Matrix Indicator (PMI), (2) only the RI, or (3) only the first PMI, and the second type CSI includes (1) a Wideband Channel Quality Indicator (WB-CQI) and a second PMI, (2) the WB-CQI and the first PMI, or (3) only the WB-CQI. |

1. A method for reporting Channel State Information (CSI) in a wireless access system which supports carrier aggregation, the method performed by a user equipment (UE) and comprising:
measuring a first type CSI for a first component carrier (CC) of two or more downlink (DL) CCs; measuring a second type CSI for a second CC of the two or more downlink (DL) CCs; and reporting 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, wherein the first type CSI includes (1) a Rank Indicator (RI) and a first Precoding Matrix Indicator (PMI) or (2) only the RI, and wherein the second type CSI includes (1) a Wideband Channel Quality Indicator (WB-CQI) and a second PMI, (2) the WB-CQI and the first PMI, or (3) only the WB-CQI. |
