Abstract: Provided are a method for transmitting uplink control information (UCI) of a terminal in a wireless communication system and the UE using the method. The method includes determining a number of coded symbols for the UCI transmission and transmitting the UCI on a physical uplink shared channel (PUSCH) based on the number of coded symbols. The number of coded symbols is determined among a first value based on a payload size of the UCI and an offset value and a second value based on a radio resource control (RRC) signal.

Abstract: A method is disclosed for detecting downlink control information. In particular, the method comprises: a step of detecting first downlink control information transmitted from a specific cell; a step of detecting second downlink control information included in a shortened downlink control channel, based on resource information about the shortened downlink control channel included in the first downlink control information, if the first downlink control information is detected; and a step of changing any one of a shortened downlink data channel, a shortened uplink data channel, and transmission/reception timings of ACK/NACK signals, which are set in advance based on the performance of the terminal, if the first downlink control information is not detected.

Abstract: This specification provides a long PUCCH using multiple slots in a wireless communication system. The method is performed by a user equipment and includes receiving first information about a TDD UL-DL slot configuration from a base station, receiving, from the base station, second information including a first parameter for a number of slots used for a transmission of the long PUCCH and a second parameter for a duration of a PUCCH symbol within a PUCCH slot, determining the multiple slots for transmitting the long PUCCH based on the first information and the second information, and transmitting the long PUCCH to the base station over the determined slots.

Abstract: Provided are a method and a device for reporting a power headroom in a wireless communication system. The device receives initial downlink control information (DCI) for physical uplink shard channel (PUSCH) transmission in a first subframe and receives triggering DCI in a second subframe. The device calculates a power headroom on the assumption that the PUSCH transmission is not performed.

Abstract: The present invention relates to a method and device for measuring channel quality by a base station having a two-dimensional active antenna system including multiple antennas. Particularly, the method comprises: receiving channel state information (CSI) generated on the basis of a first reference signal relating to a part of multiple antennas, from a terminal; selecting a precoding and a rank based on a precoding matrix indicator (PMI) and a rank indicator (RI) of the received CSI; generating a port by applying the selected precoding and the selected rank; through the generated port, transmitting, to the terminal, a physical downlink shared channel (PDSCH) and a demodulation-reference signal (DM-RS) configured for the terminal; and receiving, from the terminal, a channel quality indication (CQI) feedback for reducing a mismatch for the CQI of the CSI, wherein the CQI feedback may be generated based on the DM-RS.
