Abstract: A method is provided for receiving a sounding reference signal (SRS) in a wireless communication system. A base station transmits downlink control information to a user equipment at a first serving cell of the plurality of serving cells. The downlink control information includes a carrier indicator and a downlink assignment. When the downlink control information includes an aperiodic SRS request that indicates a triggering of an SRS transmission, the base station receives an SRS from the user equipment at the second serving cell. If the first serving cell is a frequency division duplex (FDD) and the second serving cell is a time division duplex (TDD) cell, the downlink control information includes the aperiodic SRS request. If the first serving cell is the TDD cell and the second serving cell is the FDD cell, the downlink control information does not include the aperiodic SRS request.

Abstract: A method is provided for reporting Channel State Information (CSI) in a wireless access system which supports carrier aggregation. 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.
