1. A method performed by a wireless device, the method comprising:
receiving a configuration for one or more data transmission starting positions for a configured uplink (UL) in unlicensed spectrum, the one or more data transmission starting positions comprising at least a first starting position; and
performing an UL transmission at one of the one or more data transmission starting positions based on when the wireless device is able to access a channel, the UL transmission comprising uplink control information (UCI) multiplexed in a Physical Uplink Shared Channel (PUSCH), the UCI carrying one or more parameters for unlicensed spectrum, wherein the UL transmission starts with a demodulation reference signal symbol,
wherein the one or more parameters comprises a UCI coded symbol length that is derived using an equation:

OG Complex Work Unit Math
wherein:
OCSI is a number of bits for a configured grant UCI;
if OCSI-1≥360, LCSI-1=11; otherwise LCSI-1 is the number of CRC bits for CSI part 1;
βoffsetPUSCH=βoffsetCSI-part1;
Qm is a modulation rate of the PUSCH;
R is ta coding rate of the PUSCH, and
wherein the method further comprises dropping one or more UCI coded symbols.
