摘要
Disclosed are various embodiments for scheduling use of heterogeneous frequency schemes for radio-based networks. In one embodiment, a plurality of frequency schemes that are available to be used in a geographic area by a radio-based network are determined. It is determined whether respective quality-of-service requirements associated with a plurality of wireless devices used in the geographic area, or applications executed in those devices, are capable of being met by individual ones of the plurality of frequency schemes. A schedule is generated for use of one or more of the plurality of frequency schemes in the geographic area by the radio-based network based at least in part on whether the respective quality-of-service requirements are capable of being met by the individual ones of the plurality of frequency schemes.

5G is the fifth-generation technology standard for broadband cellular networks, which is planned eventually to take the place of the fourth-generation (4G) standard of Long-Term Evolution (LTE). 5G technology will offer greatly increased bandwidth, thereby broadening the cellular market beyond smartphones to provide last-mile connectivity to desktops, set-top boxes, laptops, Internet of Things (IoT) devices, and so on. Some 5G cells may employ frequency spectrum similar to that of 4G, while other 5G cells may employ frequency spectrum in the millimeter wave band. Cells in the millimeter wave band will have a relatively small coverage area but will offer much higher throughput than 4G.
