Scheduling use of heterogeneous frequency schemes for radio-based networks
摘要
說明書
The radio-based network 103 can include capacity provisioned on one or more radio access networks (RANs) that provide the wireless network access to the plurality of wireless devices 106 over a plurality of different frequency schemes 107 through a plurality of cells 109. The RANs may be operated by different communication service providers. Each of the cells 109 may be equipped with one or more antennas and one or more radio units that send and receive wireless data signals to and from the wireless devices 106. The antennas may be configured for one or more frequency bands, and the radio units may also be frequency agile, meaning that the radio units can be dynamically adjusted to change transmit and/or receive modulation frequencies to use different frequency schemes. The antennas may be associated with a certain gain or beamwidth in order to focus a signal in a particular direction or azimuthal range, potentially allowing reuse of frequencies in a different direction. Further, the antennas may be horizontally, vertically, or circularly polarized. In some examples, a radio unit may utilize multiple-input, multiple-output (MIMO) technology to send and receive signals. As such, the RAN implements a radio access technology to enable radio connection with wireless devices 106 over the frequency scheme 107 and provides connection with the radio-based network's core network. Components of the RAN include a base station and antennas that cover a given physical area, as well as required core network items for managing connections to the RAN.
