Abstract:
1. A method for transmitting uplink control information (UCI) on a physical uplink control channel (PUCCH) in a wireless communication system, the method comprising: performing, by a user equipment, channel coding on information bits of the UCI to generate encoding information bits, wherein the information bits of the UCI include concatenation of hybrid automatic repeat request (HARQ)-ACK(acknowledgement) information bits for each of serving cells and a scheduling request (SR), and wherein the SR is appended at the end of the concatenated HARQ-ACK information bits; scrambling, by the user equipment, the encoding information bits based on a user equipment (UE)-specific scrambling sequence to generate scrambled bits; modulating, by the user equipment, the scrambled information bits to generate complex modulation symbols; block-wise spreading, by the user equipment, the complex modulation symbols based on an orthogonal sequence; and transmitting, by the user equipment, the block-wise spread complex modulation symbols to a base station.
