METHOD OF TRANSMITTING CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

A method of transmitting control information in a wireless communication system is provided to reduce interference and improve reliability even though a plurality of control information is transmitted. A base sequence is cyclically shifted as much as a CS(Cyclic Shift) amount so that a cyclically shifted sequence is generated(S1310). A modulation sequence is generated based on a modulation symbol of the control information and the cyclically shifted sequence(S1320). The modulation sequence is transmitted on a plurality of subcarriers(S1330). According to a kind of the control information, availability cyclic shifts are divided into the first part and the second part of the base sequence. The first part and the second part are classified by one or more unassigned cyclic shifts of the base sequence.
