    Abstract: Embodiments of the present invention are directed to a method and apparatus for transmitting and receiving a control signal (for example, PDCCH signal) in an asymmetric multicarrier environment. The method for transmitting a control signal for an asymmetric multicarrier in a wireless connection system according to one embodiment of the present invention comprises: determining the size of a carrier indicator field (CIF) indicating a downlink component carrier (DL CC) by which downlink data is transmitted, on the basis of a maximum value of the number of DL CCs and of the number of uplink component carriers (UL CCs) being managed in a base station; transmitting the CIF on a 1st DL CC to a terminal through a physical downlink control channel (PDCCH); and transmitting downlink data on a 2nd DL CC indicated by the CIF to the terminal through a physical downlink shared channel (PDSCH).

    Abstract: A method is presented for transmitting an Acknowledgement/Negative Acknowledgement (ACK/NACK) information at a User Equipment (UE) configured to use Physical Uplink Control Channel (PUCCH) format 3 in a wireless communication system. The UE determines that transmission of a scheduling request is configured in one uplink subframe in which a transmission of ACK/NACK information for downlink transmission in a downlink subframe set including one or more downlink subframes is to be transmitted. The UE transmits the ACK/NACK information and the scheduling request using PUCCH format 1b in the one uplink subframe, when transmission of the ACK/NACK information coincides with the one uplink subframe for the transmission of the scheduling request and at least one of specific conditions is met, (e.g., the ACK/NACK information corresponds to one Semi-Persistent Scheduling (SPS) release Physical Downlink Control Channel (PDCCH) having a Downlink Assignment Index (DAI) value of 1 in the downlink subframe set).

    Abstract: A method is provided for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information at a User Equipment (UE) in a wireless communication system. The UE is configured to use a Physical Uplink Control Channel (PUCCH) format 3 for the transmission of the ACK/NACK information. A PUCCH format between a PUCCH format 1a/1b and the PUCCH format 3 is determined for transmission of the ACK/NACK information for downlink transmission in a downlink frame set including M downlink subframes is to be transmitted, where M≥1, in one uplink subframe, according to whether at least one of specific conditions is met. The ACK/NACK information is transmitted using the determined PUCCH format in the one uplink subframe. The ACK/NACK information is transmitted by using the PUCCH format 1a/1b, when at least one of the specific conditions is met. One serving cell is configured for the UE.

    Abstract: A method for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information, and a User Equipment (UE) therefore are discussed. The method according to an embodiment includes determining a Physical Uplink Control Channel (PUCCH) format and a PUCCH resource through which ACK/NACK information is to be transmitted; and transmitting the ACK/NACK information by multiplexing the ACK/NACK information with a scheduling request, when a transmission of the scheduling request is configured. The ACK/NACK information and the scheduling request are transmitted using a PUCCH format 1b, when the ACK/NACK information corresponds to one Physical Downlink Shared Channel (PDSCH) without a corresponding Physical Downlink Control Channel (PDCCH) received only on a Primary Cell (PCell) in the downlink subframe set. The ACK/NACK information further corresponds to a Semi-Persistent Scheduling (SPS) release PDCCH having a Downlink Assignment Index (DAI) value of 1 or one PDSCH indicated by a corresponding PDCCH having a DAI value of 1.

    Abstract: A method and apparatus for transmitting control information in a wireless communication system supporting carrier aggregation (CA) is disclosed. A method for transmitting control information to a base station (BS) by a user equipment (UE) in a wireless communication system includes receiving at least one of a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH) from the base station through at least one serving cell configured in the user equipment, and transmitting control information regarding PDCCH reception or PDSCH reception indicated by the PDCCH to the base station. The control information is transmitted through a physical uplink control channel (PUCCH) of a primary cell, using control information feedback timing of at least one of the primary cell and a first cell of the at least one serving cell, and the at least one serving cell uses different uplink and downlink (UL-DL) configurations.
