Method and device for transmitting uplink control information in wireless communication system

摘要

Disclosed are a method and a device for transmitting uplink control information (UCI) by a terminal in a wireless communication system. The UCI transmission method comprises the steps of: generating an encoding information bit stream by performing channel coding for a UCI bit stream; generating complex modulation symbols by performing modulation for the generated encoding information bit stream; spreading the complex modulation symbols in block-wise on the basis of an orthogonal sequence; and transmitting the spread complex modulation symbols to a base station. The encoding information bit stream is generated by a channel coding for circularly repeating the UCI bit stream.

1. A method of transmitting, by a user equipment (UE), uplink control information (UCI) on a physical uplink control channel (PUCCH) in a wireless communication system, the method comprising:
generating encoding information bits by performing channel coding on information bits of the UCI, a length of the information bits of the UCI being smaller than a reference value M, the encoding information bits being generated by circular repetition of a sequence which is based on the information bits of the UCI; generating scrambled bits by scrambling the encoding information bits based on a UE-specific scrambling sequence; generating complex modulation symbols by modulating the scrambled bits; block-wise spreading the complex modulation symbols based on an orthogonal sequence; and transmitting the spread complex modulation symbols to a base station.
