N2 - Non-Primary Channel Access (NPCA), introduced in IEEE 802.11bn, enables stations to transmit on secondary channels when the primary is occupied, improving spectrum reuse in overlapping BSS (OBSS) environments. However, NPCA may cause cross-channel interference to other BSSs. In this paper, we investigate how NPCA frame duration influences channel utilization and throughout for other BSSs. Using a time-slotted simulation framework, we evaluate inter-BSS interactions under varying frame lengths. Our findings show that shorter NPCA frames offer throughput gains at the expense of neighboring BSS performance, whereas long frames reduce interference but provide limited benefits. These results highlight a trade-off between spectrum efficiency and coexistence fairness, offering insights for NPCA configuration in future Wi-Fi 8 systems.
