This disclosure describes systems, methods, and devices related to data path structure for multi-band operation. A neighbor awareness networking (NAN) device may determine a first NAN data link (NDL) associated with a first frequency band, a first processing core, and a first NAN management interface (NMI). The NAN device may determine a second NDL associated with a second frequency band, a second processing core, and a second NMI. The NAN device may send one or more multi-band indications of at least one of the first NMI or the second NMI, the one or more multi-band indications being indicative of at least one of the first frequency band or the second frequency band. The NAN device may establish a NAN data path (NDP) with a second NAN device using at least one of the first NDL or the second NDL.
