Title:
無線通信システムにおける制御情報の送信方法及び装置
Document Type and Number:
Japanese Patent JP5883845
Kind Code:
B2
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method for transmitting control information through a PUCCH in a wireless communication system and an apparatus for same comprising the steps of: obtaining a plurality of second modulation symbol streams corresponding to a plurality of SC-FDMA(Single Carrier Frequency Division Multiplexing) symbols by diffusing a plurality of first modulation symbol streams to form the first modulation symbol streams corresponding to the SC-FDMA symbols within a first slot; obtaining a plurality of complex symbol streams by performing a DFT(Discrete Fourier Transform) pre-coding process for the plurality of second modulation symbol streams; and transmitting the plurality of complex symbol streams through the PUCCH wherein the plurality of second modulation symbol streams are scrambled in a SC-FDMA symbol level.
