Abstract

A method, computer-readable medium, and apparatus for dynamically assigning radio resources between a frequency division duplexing (FDD) carrier and a time division duplexing (TDD) carrier is provided. The method includes monitoring radio frequency conditions and traffic load of the FDD and TDD carriers; allocating a resource assignment for a downlink on the FDD carrier or the TDD carrier, based upon the radio frequency conditions or the traffic load of the FDD and TDD carriers; and allocating a resource assignment for an uplink on the FDD carrier or the TDD carrier, based upon the radio frequency conditions or the traffic load of the FDD and TDD carriers.

monitoring radio resources of each of the FDD and TDD carriers;

allocating resource assignments for downlinks on the FDD carriers or the TDD carriers, based upon the radio resources on each of the FDD and TDD carriers;

allocating resource assignments for uplinks on the FDD carriers or the TDD carriers, based upon the radio resources of each of the FDD and TDD carriers.

7. The method of claim 6, wherein the radio resources are provided by downlink measurements from devices operating on the FDD and TDD carriers.

8. The method of claim 6, wherein the resource assignments are allocated on a burst-by-burst basis.

9. The method of claim 6, wherein the radio resources comprise at least one of radio frequency conditions and traffic load.
