Abstract
The present invention discloses a method of spectrum utilization in a wireless cellular environment with coverage of at least two wireless networks and a related apparatus. The method includes: determining a RSRP threshold; detecting, by a small-cell base station, RSRPs of at least one large-cell base station; and comparing the highest one of the detected RSRPs with the determined RSRP threshold, adopting a separate spectrum mode if the highest one of the detected RSRPs exceeds the determined RSRP threshold, and otherwise, adopting a shared spectrum mode. According to the method and apparatus of the present invention, a separate spectrum mode is adopted when the small-cell base station is relatively close to the large-cell base station to decrease interferences between the small-cell base station and large-cell base station and to increase spectrum usage efficiency in the wireless cellular environment with coverage of at least two wireless networks, however, a shared spectrum mode is adopted when the small-cell base station is relatively far from to the large-cell base station to realize sharing spectrum and increase spectrum usage efficiency in the wireless cellular environment with coverage of at least two wireless networks.
