In future radio communication systems, an uplink control channel will be transmitted properly. A user terminal has a receiving section that receives frequency hopping information, which indicates whether frequency hopping for an uplink control channel is enabled or not, and a control section that applies at least one of a spreading factor for a time-domain orthogonal cover code, a configuration of a demodulation reference code and a base sequence, to the uplink control channel, based on the frequency hopping information.

In the present invention, regarding a narrowband used in a subframe for transmitting uplink data, if a switch is made from a first narrowband used in a first subframe to a second narrowband that is different from the first narrowband, with respect to a second subframe continuing to the first subframe, a final one symbol of the first subframe and an initial one symbol of the second subframe are punctured and set as a retuning time to transmit the uplink data in the first narrowband and the second narrowband.

A method for selecting orthogonal cover codes repetition sequence for Physical Uplink Control Channel (PUCCH) transmission in a New Radio-Unlicensed (NR-U) network is provided. In embodiments disclosed herein, a set of time domain and/or frequency domain variables, Φ, is first determined to be used in a function, ƒ(Φ), that determines a selected PUCCH sequence, r.sub.l(m), among at least two PUCCH sequences to be repeated with Orthogonal Cover Codes (OCC). Accordingly, a subset of the selected PUCCH sequence, r.sub.l(m), is repeated with OCC. By employing the method disclosed herein to determine the selected PUCCH sequence, r.sub.l(m), for repetition with OCC, it is possible to satisfy the occupied bandwidth and the maximum Power Spectral Density (PSD) requirements mandated in the NR-U network.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate an uplink control information (UCI) message including a first UCI bit multiplexed with a second UCI bit, the first UCI bit having a first sequence applied and the second UCI bit having a second sequence, that is orthogonal to the first sequence, applied.
