Intra-symbol OCC mapping for transmissions such as NR-U PUCCH transmissions

A method performed by a base station, the method comprising:

• providing, to a wireless device, information that either:
• instructs the wireless device to use a particular 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 being for application of an intra data symbol Orthogonal Cover Code, OCC, to the I/Q symbol repetitions;
• or
• assists the wireless device with selection of a particular repetition mapping for I/Q symbol repetitions within an OFDM or DFT-s-OFDM symbol of an uplink transmission, the I/Q symbol repetitions being for application of an intra data symbol OCC to the I/Q symbol repetitions.

A base station for a cellular communications network, the base station adapted to:

• provide, to a wireless device, information that either:

• or
• assists the wireless device with selection of a particular repetition mapping for I/Q symbol repetitions within an OFDM or DFT-s-OFDM symbol of an uplink transmission, the I/Q symbol repetitions being for application of an intra data symbol OCC to the I/Q symbol repetitions.
