  • Patent number: 11303493
    Abstract: Methods and apparatuses are described herein for transmit diversity in an uplink control channel. A wireless transmit/receive unit (WTRU) may perform a Discrete Fourier Transform (DFT) precoding operation on a data symbol sequence segment to generate a DFT precoded segment. The WTRU may then perform a Space Frequency Block Coding (SFBC) operation on the DFT precoded segment to generate a SFBC processed segment. The data symbols of the DFT precoded segment may be reordered in the SFBC processed segment. The WTRU may map the DFT precoded segment to a first set of contiguous subcarriers and the SFBC processed segment to a second set of contiguous subcarriers. The WTRU may then transmit a first DFT spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) signal on the first set of contiguous subcarriers via a first antenna port and a second DFT-s-OFDM signal on the second set of contiguous subcarriers via a second antenna port.
