Abstract: A method and a user equipment (UE) for receiving a power headroom report in a wireless access system that supports a carrier aggregation are discussed. The method according to an embodiment includes transmitting by an eNB to a UE an uplink transmission grant allocating uplink resources on a predetermined subframe in an anchor uplink component carrier (UL CC); and receiving the power headroom report by the eNB from the UE. The power headroom report includes a power headroom value for the anchor UL CC, when the eNB has configured the UE for a simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission. The method further includes reporting the power headroom value to a base station. The power headroom value is calculated.

Abstract: A method and apparatus for transmitting an uplink signal in a wireless communication system are discussed. The method includes multiplexing control information in all layers with a plurality of data blocks of the uplink signal; and transmitting the uplink signal to a base station, wherein the number of modulation symbols per layer for the control information is determined using a reciprocal of a sum of spectral efficiencies for respective data blocks of the plurality of data blocks, and a spectral efficiency for a data block is obtained based on a ratio of a size of the data block to the number of resource elements (REs) for an initial physical uplink shared channel (PUSCH) transmission of the data block.

Abstract: A method is presented 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), supporting at least one cell including a primary cell, receives a radio resource control (RRC) message indicating resource allocation information used for a first PUCCH format. The UE receives a first physical downlink shared channel (PDSCH) and a second PDSCH in one of the M downlink TDD subframes, wherein the second PDSCH is received with a downlink assignment index (DAI). The UE selects a physical uplink control channel (PUCCH) format among a plurality of PUCCH formats including the first PUCCH format and a second PUCCH format, and transmits a positive-acknowledgement (ACK)/negative-acknowledgement (NACK) signal for the first and second PDSCHs by using the selected PUCCH format.

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 for adaptively allocating resources of an uplink control channel according to a system situation is disclosed. If a base station (BS) recognizes the system situation, establishes control information for resource allocation, and transmits the control information to a mobile station (MS), the mobile station (MS) allocates resources for transmitting uplink control information using a specific block or a specific resource distribution method according to the corresponding control information. The system situation may be changed according to the number of users contained in the BS's coverage or the usage of a multi-antenna. The variation of the system situation is actively reflected so that the uplink channel resources can be effectively used.
