    Abstract: The present invention provided a method and apparatus for reporting a channel quality in a wireless communication system. A terminal receives an uplink grant from a base station via one of a plurality of downlink component carriers (CCs). The uplink grant includes a channel quality indicator (CQI) request for instructing uplink allocation and CQI reporting. The terminal reports the CQI of the downlink CC being linked to the base station. The downlink CC being linked is one of the plurality of downlink CCs, which is linked to the uplink CC for which the uplink allocation is scheduled. A method and an apparatus for reporting channel quality are discussed. The method according to an embodiment includes receiving, by a terminal configured with a plurality of downlink component carriers (CCs), control information from a base station, the control information including an uplink allocation and a CQI request, the control information including a carrier indicator field (CIF) indicating an uplink CC in which the uplink allocation is scheduled; and transmitting, by the terminal to the base station, the CQI through an uplink CC. The CQI request indicates one of: a triggering of CQI reporting for one downlink CC linked to the uplink CC, indicated by the CIF, among the plurality of downlink CCs; and a triggering of CQI reporting for a first group of downlink CCs among the plurality of downlink CCs.

    Abstract: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for performing processes in which a terminal determines control channel allocation, as well as to an apparatus for the method. The method comprises the following steps: monitoring, on a first carrier, a first search space, containing a control channel candidate set, for control channels having no carrier indication information; and monitoring, on a second carrier, a second search space, containing a control channel candidate set, for control channels having carrier indication information. If the terminal is set to monitor a plurality of control channel candidates which have the same radio network temporary identifier (RNTI), the same information size, and the same first control channel element (CCE) in the first search space and in the second search space, the control channels are received only in the first search space on the first carrier.

    Abstract: A method of reporting control information in a wireless communication system in which M downlink time divisional duplex (TDD) subframes are associated with an uplink TDD subframe. A user equipment (UE) receives resource allocation information used for a first physical uplink control channel (PUCCH) format. The UE selects a PUCCH format among a plurality of PUCCH formats including the first PUCCH format and a second PUCCH format. The second PUCCH format is selected if the UE receives a first physical downlink shared channel (PDSCH) in one of the M downlink TDD subframes on the primary cell. The UE receives a second PDSCH with a downlink assignment index (DAI) in one of the M downlink TDD subframes on the primary cell. The UE does not receive a first physical downlink control channel (PDCCH) corresponding to the first PDSCH on the primary cell.

    Abstract: A method is described for transmitting a control signal in a wireless communication system. A wireless communication system supporting multiple antennas, transmits, by a user equipment (UE), a control signal on an uplink control channel at a subframe i. Furthermore, an uplink transmit power PPUCCH(i) for the uplink control channel at the subframe i is determined based on a mathematical equation. Additionally, the mathematical equation includes a min function and uses parameters including PCMAX(i), P0_PUCCH, ΔF_PUCCH(F), g(i), PL, Δ(M) and PL where PCMAX(i) is a configured UE transmit power in subframe i, P0_PUCCH is a parameter composed based on provisions by a higher layer, ΔF_PUCCH(F) is a parameter provided by the higher layer, PL is a downlink pathloss estimate calculated in the UE, and g(i) is a value relating to a UE specific value.
