Abstract:
1. A method for transmitting control information at a user equipment (UE) via a physical uplink control channel (PUCCH) in a wireless communication system, the method comprising: coding a plurality of control information to obtain a single codeword; obtaining a first modulation symbol sequence from the single codeword; obtaining a plurality of second modulation symbol sequences corresponding to a slot in the PUCCH from the first modulation symbol sequence; obtaining a plurality of third modulation symbol sequences by circularly shifting the plurality of second modulation symbol sequences in a time domain; obtaining a plurality of complex symbol sequences in a frequency domain by performing Discrete Fourier Transform (DFT) precoding for the plurality of third modulation symbol sequences; and wherein different circular shift values are applied to each of the plurality of second modulation symbol sequences.
