Abstract:
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.
