Patent ID: 8767661

Claim:
A method for transmitting control information through a physical uplink control channel (PUCCH) at a user equipment (UE) in a wireless communication system, the method comprising: modulating control information bits to generate N 1 modulation symbols, wherein N 1 is twice of a number of subcarriers in one resource block (RB); block-wise multiplying the first N 1 /2 modulation symbols of the N 1 modulation symbols by each element of a first orthogonal code to generate a first plurality of sequences; block-wise multiplying the second N 1 /2 modulation symbols of the N 1 modulation symbols by each element of a second orthogonal code to generate a second plurality of sequences; and transmitting the first and second plurality of sequences in a subframe, wherein each sequence of the first plurality of sequences is mapped to a corresponding single carrier frequency division multiple access (SC-FDMA) symbol in a 1 st slot of the subframe, and each sequence of the second plurality of sequences is mapped to a corresponding SC-FDMA symbol in a 2 nd slot of the subframe, wherein each sequence of the first and second plurality of sequences is discrete fourier transformed.
