Abstract: Machines or networked devices such as internet of things (IoT) devices operate to generate an unlicensed narrowband (U-NB) IoT communication based on time domain multiple carrier aggregation operations with component carriers. These component carriers can comprise a component carrier that is anchored to a long term evolution (LTE) licensed band, or entirely comprise unlicensed carrier components that are unanchored to the LTE component carrier in a standalone configuration. Communication circuitry such as a radio frequency interface can transmit the U-NB IoT communication in standalone communications over a low power IoT network in an unlicensed band.
