Abstract: A method of acquiring information on a resource region for transmitting PHICH and a method of receiving PDCCH using the same are disclosed. The resource region for transmitting the PHICH can be specified by first information corresponding to the per-sub frame PHICH number and second information corresponding to a duration of the PHICH within the subframe. The first Information can be specified into a form resulting from multiplying a predetermined basic number by a specific constant. And, the specific constant can be transmitted via PBCH. Moreover, the second information can be acquired from the PBCH as well.

Abstract: A method for uplink transmission in a wireless communication system. A user equipment (UE) determines whether to transmit or drop a sounding reference signal (SRS) on a last symbol in a ith subframe. The SRS is dropped if multiple timing advance groups (TAGs) are configured, if a portion of the last symbol of the ith subframe for transmitting the SRS toward a first serving cell in a first TAG is overlapped with an (i+1)th subframe for transmitting an uplink channel toward a second serving cell in a second TAG and if a total power of the SRS and the uplink channel exceeds a maximum value on the overlapped portion of the last symbol.

Abstract: A method for controlling transmission powers by a communication apparatus in a wireless communication system supporting a plurality of component carriers. When a sounding reference symbol (SRS) transmission overlaps with a physical uplink shared channel (PUSCH) transmission in a time domain, the communication apparatus checks 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 drops the SRS transmission if the total of the PUSCH transmission power and the SRS transmission power exceeds the maximum transmission power configured for the communication apparatus.

Abstract: A method and apparatus for transmitting control information are discussed. The method can include generating uplink control information (UCI) and transmitting the UCI through an physical uplink control channel (PUCCH) in a subframe, wherein when the subframe is configured for transmission of a scheduling request (SR) and when transmission of a hybrid automatic repeat request (HARD)-acknowledgement (ACK) coincides with the subframe, transmission power of the PUCCH is determined based on a number of HARQ-ACK information bits and a SR bit. A value of the SR bit can be determined by whether or not the subframe is configured for a scheduling request.
