1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
multiplexing uplink control information (UCI) symbols and phase tracking reference signal (PTRS) symbols to generate a block of modulation symbols;
spreading the block of modulation symbols based on an orthogonal sequence with a spreading factor M to provide a length-L spread modulation symbol sequence, wherein the block of modulation symbols comprises L/M modulation symbols, and L is a number 12 of subcarriers in a resource block;
discrete fourier transforming the length-L spread modulation symbol sequence to provide a length-L complex-valued symbol sequence; and
transmitting the length-L complex-valued symbol sequence through an orthogonal frequency division multiplexing (OFDM)-based symbol for a physical uplink control channel (PUCCH),
wherein the length-L spread modulation symbol sequence is configured as follows:
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
wherein Ux represents x-th UCI symbol, Rx represent x-th PTRS symbol, and Cx represent x-th element of the orthogonal sequence.
