Abstract: A method and a user equipment for controlling an uplink transmission at in a wireless communications system are discussed, the user equipment being configured with multiple component carriers. The method according to an embodiment includes receiving, from a base station, Radio Resource Control (RRC) configuration information for a channel status information report; and performing a procedure for periodically transmitting channel status information to the base station. If the corresponding downlink component carrier is in an active state at a time for transmitting the channel status information, a transmission of the channel status information report is performed at the time. If the corresponding downlink component carrier is in a non-active state at a time for transmitting the channel status information report, the transmission of the channel status information report is skipped at the time. Signal reception is limited by the user equipment on a downlink component carrier in the non-active state.

Abstract: A method for configuring an acknowledgement for hybrid automatic repeat request (HARQ), and a user equipment therefore are discussed. The method according to one embodiment includes receiving downlink data through one of first and second downlink component carriers; and determining a resource used for a physical uplink control channel (PUCCH). The resource used for the PUCCH is determined based on a downlink component carrier. If downlink data is received through the first downlink component carrier, the resource used for the PUCCH is determined by using a control channel element (CCE) of a physical downlink control channel (PDCCH). If the downlink data is received through the second downlink component carrier, the resource used for the PUCCH is determined by using a radio resource control (RRC) message. The method according to the embodiment further includes transmitting an acknowledgement (ACK)/negative-acknowledgement (NACK) signal for the downlink data using the resource used for the PUCCH.

The method comprises: transmitting uplink data through a physical uplink shared channel (PUSCH); and receiving ACK/NACK with respect to the uplink through a physical hybrid-ARQ indicator channel (PHICH), wherein a serving cell that receives the ACK/NACK is selected from one or more serving cells, which the user equipment monitors to detect an uplink grant that schedules the PUSCH.

Abstract: Provided is a method and an apparatus for transmitting uplink control information by a terminal in wireless communication system. When a PUCCH resource used for transmitting only periodic CSI from a subframe, the resource is a first resource, and a resource indicated by ARI is a second resource, when a setting allows transmitting together ACK/NACK and the periodic CSI through a PUCCH from the same subframe, the first resource and the second resource are mutually exclusive, and the second resource that is used for transmitting together the ACK/NACK and the periodic CSI uses the resource indicated by the ARI from resources determined by an RRC.

Abstract: A method for transmitting acknowledgement/negative acknowledgement (ACK/NACK) signals by an apparatus in a wireless communication system. The apparatus spreads ACK/NACKs using spreading codes of a spreading factor, the spreading factor being one of a first spreading factor equal to 2 and a second spreading factor equal to 4. The apparatus transmits one or more physical hybrid automatic repeat request (HARQ) indicator channel (PHICH) groups allocated in units of four resource elements, each PHICH group carrying up to four ACK/NACK signals for the first spreading factor, and up to eight ACK/NACK signals for the second spreading factor. A total number of allocated PHICH groups for the first spreading factor is determined as twice a total number of allocated PHICH groups for the second spreading factor. Each ACK/NACK signal is identified using an index pair of a PHICH group index and a spreading code index.

Abstract: A method for receiving, by a first device, data from a second device. The first device receives modulation and coding related information and resource related information for a transport block with a size for the data, and receives second cyclic redundancy check (CRC) attached code blocks to which a first CRC attached transport block corresponding to the transport block is mapped. The first device obtains the transport block with the size from the second CRC attached code blocks based on the modulation and coding related information and resource related information. The modulation and coding related information and the resource related information represent the size of the transport block. The size of the transport block is one of a plurality of predetermined transport block sizes. The plurality of predetermined transport block sizes are predetermined such that all the second CRC attached code blocks have a same size as each other.

Abstract: A method of adjusting a transmit power for signals in a wireless communication system is provided. A user equipment (UE) sets a first transmit power for a first signal and a second transmit power for a second signal. If a total transmit power of the first transmit power for the first signal and the second transmit power for the second signal exceeds a maximum transmit power, the UE scales the first transmit power for the first signal and the second transmit power for the second signal. The first transmit power for the first signal and the second transmit power for the second signal are scaled with a scaling factor parameter. Values of the scaling factor parameter are the same across a plurality of serving cells.
