Abstract:
Systems and methods are disclosed herein for intra-symbol Orthogonal Cover Code (OCC) mapping for transmissions such as, e.g., New Radio-Unlicensed (NR-U) Physical Uplink Control Channel (PUCCH) transmissions. In this regard, embodiments of a method performed by a wireless device and corresponding embodiments of a wireless device are disclosed. In some embodiments, a method performed by a wireless device comprises selecting a repetition mapping for In-Phase/Quadrature-Phase (I/Q) symbol repetitions within an Orthogonal Frequency Division Multiplexing (OFDM) or Discrete Fourier Transform spread OFDM (DFT-s-OFDM) symbol of an uplink transmission. The I/Q symbol repetitions are for application of an intra data symbol OCC to the I/Q symbol repetitions. The method further comprises transmitting an uplink transmission using the selected repetition mapping. In this manner, performance is improved. Embodiments of a method of operation of a base station and corresponding embodiments of a base station are also disclosed.
