Abstract: A radio resource management system and method, the system includes: an acquisition device acquiring a range to be protected of a high priority system and a positioning range of a low priority system based on position information about at least one high priority system and at least one low priority system; a selection device selecting, with regard to the high priority system in at least one high priority system group, a position where a reference generated by a low priority system to the high priority system satisfies a pre-determined condition, for each low priority system within the positioning range thereof, as a reference position of the low priority system based on the range to be protected of the high priority system; and a parameter determination device determining a working parameter of the low priority system for the high priority system based on the reference position of each low priority system.

Abstract: The present disclosure provides a radio frequency spectrum management apparatus, method, system and secondary user apparatus for a cognitive radio system comprising primary systems and secondary systems, the radio frequency spectrum management apparatus comprises circuitry configured to: acquire, according to position variation information of respective secondary user groups in the secondary systems, path loss information at the positions before and after the movement of respective secondary user groups respectively, wherein, the secondary user group comprises one or more secondary users; and determine an adjustment to the usage of frequency spectrums of the secondary users, according to the variation of the path loss information at the positions before and after the movement of respective secondary user groups. The present disclosure may at least improve the efficiency of adjusting the frequency spectrum resource.
