This disclosure is directed to allocation of one or more radio bands to a user equipment (UE) for establishing a radio link with a radio node (e.g., eNodeB or gNodeB). The radio bands may include a shared band, such as citizens band radio service (CBRS), a primary licensed band, such as the B66 band, and/or an unlicensed band, such as B46 band. A radio communications system may consider a variety of parameters associated with the distance of a UE from a radio node, signal strength of a signal from the UE, the services requested by the UE, and/or spectral availability of the each of the radio bands to determine which radio band(s) to allocate to the UE. In some cases, the radio band allocated to a UE may be dynamically changed by the radio communications system as conditions related to the UE and/or the mobile network change.
