A network device may determine a sequence. The sequence may identify an order in which particular unlicensed bands, of a plurality of unlicensed bands in an unlicensed spectrum, are to be assigned for the transmission of data flows. The network device may provide information identifying the sequence via a licensed band to a user device to cause the user device to transmit or receive the data flows via the particular unlicensed bands identified in the sequence in the order in which the particular unlicensed bands are to be assigned; and transmit or receive, to or from the user device, the data flows via the particular unlicensed and the licensed bands.
