This disclosure provides systems, methods, and apparatuses for channel occupancy time (COT) sharing arrangements when two or more COTs are associated with different durations, and provides arrangements for base station scheduling of downlink transmissions and selection of a listen-before-talk (LBT) configuration when two or more COTs are associated with different user equipment (UE) transmission endpoints. Furthermore, this disclosure provides systems, methods, and apparatuses for UE-side communication in accordance with scheduling information determined based on such COT sharing arrangements. By providing COT sharing arrangements when two or more COTs are associated with different durations, unlicensed channel utilization may be improved and throughput may be increased relative to when only one UE's COT can be used by the base station. By providing arrangements for scheduling downlink transmissions and selecting an LBT configuration, unlicensed channel utilization may be improved and access to the unlicensed medium may be streamlined.
