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 and device for feeding back channel state information (CSI) by a user equipment (UE) in a wireless communication system applied three-dimensional (3D) beamforming. The method includes: receiving a pilot signal (reference signal) from a base station; configuring a CSI transmission mode in one of a first transmission mode and a second transmission mode based on motion information of the UE; and feeding back the CSI based on the configured CSI transmission mode. The first transmission mode transmits the CSI including precoding matrix index (PMI) information for one of vertical beamforming or horizontal beamforming. The second transmission mode transmits the CSI including PMI information for both vertical beamforming and horizontal beamforming.

Abstract: The present application provides a method for allocating resources in a wireless communication system using multiple antennas. The method for allocating resources comprising: transmitting a reference signal to first-type terminals based on type information of a plurality of terminals; receiving channel estimation information from the first-type terminals that have received the reference signal; generating beams based on the received channel estimation information; and allocating resources for the generated beams. First-type beams for the first-type terminals are primarily generated and allocated, and on the basis of the generated first-type beams, second-type beams for second-type terminals may be non-orthogonally generated and allocated when the resources for the beams are allocated.
