Abstract

Systems and methods provide reliable voice connections and highest possible data rates in New Radio dual-connectivity environments, given limitations of available spectrum. A system includes a first wireless station and a second wireless station. The first wireless station provides a shared spectrum of a first frequency band, the shared spectrum including a first spectrum for a first cellular wireless standard and a second spectrum for a second cellular wireless standard. The second wireless station is at least partially within a coverage area of the first wireless station and provides a third spectrum for the second cellular wireless standard. The third spectrum is a millimeter wave (mmWave) spectrum. The first wireless station broadcasts cell parameters barring an end device in an idle mode from camping on the second spectrum. The first wireless station or the second wireless station triggers the end device to swap to the second spectrum when a paging request for a voice call is received.
