Abstract:
A method of a user equipment for performing TDD (Time Division Duplex) operation in a wireless communication system is discussed. The method according to one embodiment includes receiving RRC (radio resource control) signaling indicating whether or not a TDD subframe is being reconfigured; monitoring a PDCCH (Physical Downlink Control Chanel) related with reconfiguring the TDD subframe, if the RRC signaling indicates the TDD subframe is being reconfigured; and performing a TDD operation based on the PDCCH for the reconfiguring the TDD subframe, depending on whether a TDD uplink-downlink configuration indicates the TDD subframe is configured as a special subframe or not.

Abstract:
A method for transmitting uplink control information by a user equipment (UE) configured with a plurality of cells including a primary cell and a secondary cell in a wireless communication system is discussed. The method includes identifying, by the UE, a Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK)(0) and a HARQ-ACK(1); and transmitting, by the UE, bits b(0)b(1) using a Physical Uplink Control Channel (PUCCH) resource among a plurality of PUCCH resources based on the HARQ-ACK(0) and the HARQ-ACK(1) to a base station (BS) for identifying the HARQ-ACK(0) and the HARQ-ACK(1). The b(0)b(1) and the PUCCH resource are given according to a relation including Table 1, where the HARQ-ACK(0) indicates an ACK/Negative ACK (ACK/NACK)/Discontinuous Transmission (DTX) response to a data block related to the primary cell, and the HARQ-ACK(1) indicates an ACK/NACK/DTX response to a data block related to the secondary cell.

Abstract:
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.
