Performing wireless transmissions over a unified air interface that span portions of both the primary band and the complementary band may provide improved throughput and spectral efficiency in next generation networks. Wireless transmissions spanning both the licensed and unlicensed spectrum carry data in different frame formats over the respective primary and complementary bands. For example, frames communicated over the primary band may have a different channel structure (e.g., different size, placement, orientation, etc.) than frames communicated over the complementary band. Wireless transmissions spanning the licensed and unlicensed spectrum may also utilize different access schemes and/or waveforms over the respective primary and complementary bands. Embodiment unified air interfaces may be dynamically configurable via software defined radio (SDR) signaling instructions.
