METHOD AND DEVICE OF TRANSMITTING CONTROL INFORMATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a wireless communication system. In more detail, a method and device of transmitting a PUCCH signal in a wireless communication system include: (a) performing block-wise spreading on a first modulation symbol column by using a length-5 orthogonal sequence corresponding to a sequence index; (b) performing block-wise spreading on a second modulation symbol column by using a length-4 orthogonal sequence corresponding to the sequence index; (c) performing each cyclic shift and Discrete Fourier Transform (DFT) pre-coding on a plurality of modulation symbol columns obtained from (a) to (b); and (d) mapping a plurality of complex symbols obtained from (c) into a physical resource for PUCCH transmission.
