    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.

    Abstract: A method for transmitting uplink control information at a communication apparatus in a time division duplex (TDD) wireless communication system. The method according to one embodiment includes receiving at least one physical downlink control channel (PDCCH) or at least one physical downlink shared channel (PDSCH); and generating reception response information for the at least one PDCCH or the at least one PDSCH. When the reception response information and channel status information are configured to be transmitted in a same subframe, if a certain condition is satisfied, the reception response information and the channel status information are transmitted together using a first physical uplink control channel (PUCCH) format. The certain condition includes a first condition of a single PDCCH transmission only on a primary cell (PCell) that has a downlink assignment index (DAI) initial value and indicates a semi-persistent scheduling (SPS) release being present.

    Abstract translation: 一种用于在时分双工(TDD)无线通信系统中的通信装置处发送上行链路控制信息的方法。 根据一个实施例的方法包括:接收至少一个物理下行链路控制信道(PDCCH)或至少一个物理下行链路共享信道(PDSCH); 以及生成用于所述至少一个PDCCH或所述至少一个PDSCH的接收响应信息。 当接收响应信息和信道状态信息被配置为在相同子帧中发送时,如果满足某个条件,则使用第一物理上行链路控制信道(PUCCH)格式一起发送接收响应信息和信道状态信息。 该特定条件包括仅在具有下行链路分配索引(DAI)初始值并且指示存在半持久调度(SPS)释放的主小区(PCell)上的单个PDCCH传输的第一条件。
