Scheduling use of heterogeneous frequency schemes for radio-based networks
摘要
說明書
The present disclosure relates to scheduling the use of heterogeneous radio frequency schemes in radio-based networks. Radio-based networks may utilize one or more different radio frequency schemes for communication between base stations and client devices. In some scenarios, a radio-based network may be provisioned with licensed spectrum, but licensed spectrum may be limited, oversubscribed, costly, or otherwise undesirable to use. In other scenarios, a radio-based network may use publicly accessible unlicensed spectrum. Unlicensed spectrum may include the whitespaces in the broadcast television bands; the 2.4 GHz, 5 GHz, and other bands used by Wi-Fi and/or Bluetooth; the Citizens Broadband Radio Service (CBRS) band at 3.5 GHz; and other frequency bands.
In some cases, there may be priority or licensed users in the unlicensed spectrum that should be protected (e.g., wireless microphones in the television whitespaces, licensed users in the CBRS band, etc.). Also, there may be current and future usage of the unlicensed spectrum that can cause interference that can inhibit use of the unlicensed spectrum by radio-based networks. While a set of unlicensed frequencies may be usable for a cell at one time, the same set of unlicensed frequencies may be unusable at a later time. Likewise, a set of unlicensed frequencies may work in one cell but not be viable in another cell. Further, a particular set of unlicensed frequencies may work fine in a cell for an application with a relatively low quality-of-service requirement, but the same unlicensed frequencies may fail to deliver adequate connectivity for an application with a relatively high quality-of-service requirement.
