1. Baseband circuitry, comprising:
processing circuitry configured to:
receive system information comprising a first random access (RA) preamble length and a second RA preamble length, the first RA preamble length and the second RA preamble length being configured based on shared spectrum channel access;
generate a physical RA channel (PRACH) message comprising a RA preamble according to the second RA preamble length;
send the PRACH message to an interface with radio interface (RF) circuitry; and
generate configured grant (CG) uplink control information (UCI) (CG-UCI) comprising an indication of no channel occupancy time (COT) sharing,
wherein the CG-UCI is generated for a CG physical uplink shared channel (PUSCH), the CG-UCI corresponds to a UE-initiated COT, and the indication of the no COT sharing corresponds to an index associated with a row of a COT sharing table.
