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 1DL CC to a terminal through a physical downlink control channel (PDCCH); and transmitting downlink data on a 2DL CC indicated by the CIF to the terminal through a physical downlink shared channel (PDSCH).

Method and and receiving control signal for merging carriers in transmission

A method is provided for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information in a wireless communication system. A User Equipment (UE) configures a Physical Uplink Control Channel (PUCCH) format 3 for transmission of the ACK/NACK information. The UE transmits the ACK/NACK information for downlink transmission in a downlink subframe set including M downlink subframes in one uplink subframe, wherein M>1. A plurality of serving cells are configured for the UE and include one Primary Cell (PCell) and at least one Secondary Cell (SCell). The UE transmits the ACK/NACK information using a PUCCH format 1b when a first condition is met that comprises a condition in case where the ACK/NACK information corresponds to one Physical Downlink Shared Channel (PDSCH) without a corresponding Physical Downlink Control Channel (PDCCH) received only on the PCell in the downlink subframe set and the ACK/NACK information corresponds to an additional PDSCH indicated by detection of one corresponding PDCCH.

Method and device for transmitting/receiving uplink control information in wireless communication system

The present disclosure relates to a communication method and system for converging a 5-Generation (5G) communication system for supporting higher data rates beyond a 4-Generation (4G) system with a technology for Internet of Things (IoT).
