    Abstract: A method is provided for a User Equipment (UE) operating in a wireless communication system. The method includes monitoring a control channel candidate with a downlink control information (DCI) format size in a plurality of search spaces. Each of the plurality of search spaces corresponds to a respective carrier indicator field (CIF) value. The method further includes transmitting or receiving data using downlink control information which is detected by monitoring the control channel candidate. In a state that control channel candidates have different values of carrier indicator field for the DCI format size, the control channel candidate with the DCI format size is received in any search space corresponding to any of the different values of carrier indicator field for the DCI format size.

    Abstract: Provided is a method of transmitting ACK/NACK in a TDD-based wireless communication system. The method includes: receiving M downlink subframes associated with an uplink subframe n in each of two serving cells; determining four candidate resources based on the M downlink subframes received in each of the two serving cells; and transmitting an ACK/NACK response for the M downlink subframes by using one resource selected from the four candidate resources in the uplink subframe n, wherein the two serving cells includes a first serving cell and a second serving cell, and wherein among the four candidate resources, a first resource and a second resource are associated with a PDSCH or a SPS release PDCCH for releasing semi-persistent scheduling received in the first serving cell, and a third resource and a fourth resources are associated with a PDSCH received in the second serving cell.

    Abstract: A method for controlling transmission powers by a communication apparatus in a wireless communication system supporting a plurality of component carriers; and a communication apparatus therefore are discussed. The method according to one embodiment includes controlling transmission powers for one or more channels per each component carrier; when a sounding reference symbol (SRS) transmission overlaps with a physical uplink shared channel (PUSCH) transmission in a time domain, checking whether a total of a PUSCH transmission power for the PUSCH transmission on a first component carrier and a SRS transmission power for the SRS transmission on a second component carrier exceeds a maximum transmission power configured for the communication apparatus; and dropping the SRS if the total of the PUSCH transmission power and the SRS transmission power exceeds the maximum transmission power configured for the communication apparatus.
