1. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
receiving a downlink transmission; and
sending 1 bit or 2 bits of uplink control information (UCI) in each resource block (RB) of a physical uplink control channel (PUCCH) transmission comprising an interlace of a plurality of RBs in an active bandwidth part (BWP) of an unlicensed carrier,
wherein a respective low peak-to-average power (PAPR) sequence is used to map the PUCCH transmission repetitively, once to each RB of the plurality of RBs of the interlace,
wherein each respective low PAPR sequence includes a different cyclic shift of a same base sequence in each RB,
wherein each different cyclic shift of the respective low PAPR sequence used in mapping the PUCCH transmission to each RB of the interlace, is a function of a RB index of the respective RB, and
wherein the UCI indicates either an acknowledgement (ACK) or a negative ACK (NACK) of the downlink transmission.
