Claim of US Patent No. 10,397,905

1. A method for 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:receiving a scheduling request (SR) configuration from a base station;
generating UCI information bits comprising an SR bit and hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits for a plurality of component carriers (CCs),
wherein the SR bit is located at the end of the UCI information bits;
performing channel coding on information bits of the UCI to generate encoded information bits;
generating modulation symbols by modulating the encoded information bits;
spreading the modulation symbols with an orthogonal code; and
transmitting the spread modulation symbols to the base station on a physical uplink control channel (PUCCH).
