摘要： 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.

摘要： A mobile communications base station has a service quality detection unit that monitors and measures communication qualities of wireless terminals currently located in the service area, and a packet classification unit that classifies packets addressed to the wireless terminals into two or more groups based on the measured communication qualities. The base station also has a buffering delay measuring unit that measures buffering delay of the packets for each of the groups. A transmission priority detection unit of the base station determines the order of priority for transmitting the packets based on the measured buffering delay in comparison with a prescribed threshold value. A resource allocation unit of the base station allocates the radio resources to the packets based on the order of priority to transmit the packets to the associated wireless terminals.
