1. A baseband processor, comprising:
one or more processors configured to:
process a configured grant of a physical uplink shared channel (PUSCH) for an unlicensed communication, the configured grant indicating the PUSCH being type A or type B;
determine a number M of demodulation reference signals (DMRSs) and a number N of starting symbol occasions in a slot in response to initiation of a channel access for the PUSCH, wherein M and N comprise an integer of at least two, respectively;
wherein, responsive to the PUSCH being type A, uplink control information (UCI) is mapped to a resource located before a last DMRS in the slot and after a first DMRS in the slot, and
wherein, responsive to the PUSCH being type B, the UCI is mapped to a resource located after the last DMRS in the slot; and
a radio frequency (RF) interface, configured to provide, to RF circuitry, data for transmitting the unlicensed communication based on the configured grant.
