Method and apparatus of switching communications from a first channel to a second channel of higher-frequency
A method and apparatus can be configured to measure channel conditions of a first channel ( 310 ). The first channel can correspond to a first frequency. The method can also include predicting whether the channel conditions of a second channel are favorable for offloading communication occurring on the first channel to the second channel based on measurements performed on the first channel ( 320 ). The second channel can correspond to a second frequency. The second frequency can be higher than the first frequency. The method can also include determining a rate of occurrence for monitoring the second channel based on the results of the predicting ( 330 ).
