Embodiment Construction

[0038] The techniques described below can be used in various wireless communication systems such as Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Orthogonal Frequency Division Multiple Access (OFDMA), single Carrier Frequency Division Multiple Access (SC-FDMA) and more. CDMA may be implemented by means of radio technologies such as Universal Terrestrial Radio Access (UTRA) or CDMA-2000. TDMA may be implemented by means of radio technologies such as Global System for Mobile communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data Rates for GSM Evolution (EDGE). OFDMA may be implemented with radio technologies such as Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802-20, Evolved UTRA (E-UTRA), and the like. UTRA is part of the Universal Mobile Telecommunications System (UMTS). 3rd Generation Partnership Project (3GPP) Long Term Evolution (...

Abstract

A method of transmitting uplink control information of a user equipment is provided. The method includes: generating the uplink control information repeatedly as many as a uplink data transmission layer; modulating the uplink control information to generate a plurality of repeated modulation symbol; applying a precoding matrix to the plurality of repeated modulation symbols to generate a plurality of first precoded symbol; and transmitting the plurality of first precoded symbols respectively through a plurality of antennas in an uplink subframe comprising a plurality of single carrier frequency division multiple access(SC-FDMA) symbols in a time domain and a plurality of subcarriers in a frequency domain.

Description

technical field [0001] The present invention relates to wireless communication, and more particularly, to a method and apparatus for transmitting uplink control information by a user equipment to a base station. Background technique [0002] Standardization work for advanced International Mobile Telecommunications (IMT), which is a next-generation (ie, post-third generation) mobile communication system, is carried out in the International Telecommunication Union Radiocommunication Sector (ITU-R). IMT-Advanced aims to support Internet Protocol (IP)-based multimedia services at a data transfer rate of 1 Gbps in a steady or slow moving state, or 100 Mbps in a fast moving state. [0003] The 3rd Generation Partnership Project (3GPP) is a system standard that meets the needs of IMT-Advanced and prepares for Advanced Long-Term Evolution (LTE) based on Orthogonal Frequency Division Multiple Access (OFDMA) / Single Carrier Frequency Division Multiple Access (SC-FDMA) transmission, It...
