METHOD AND DEVICE OF TRANSMITTING CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method for receiving control information.SOLUTION: The method includes the following steps of: receiving a reference signal from a base station, by the UE; identifying respective numbers of bits of a plurality of pieces of control information on the basis of a type of a control message transmitted to the base station by the UE; generating the plurality of pieces of control information on the basis of the received reference signal and the respective numbers of bits of the plurality of pieces of control information; encoding the plurality of pieces of control information in cooperation by using a block code; modulating the encoded control information by using a modulation system to generate a plurality of modulated symbols; applying a constant amplitude zero auto-correlation (CAZAC) sequence to the modulated symbol to generate a plurality of CAZAC-modulated sequences; and transmitting the plurality of CAZAC-modulated sequences by using a plurality of sub carriers.
