SYSTEM AND METHOD FOR OPPORTUNISTIC SPECTRUM-SHARING BY SPECTRUM AGILE RADIOS(SARA) |
摘要 |
An apparatus (301. i), system (300) and method are provided for opportunistically sharing spectrum between and among Spectrum Agile Radio (SARA) devices (301.i), primary (3O2.i) and secondary devices (303.i). A primary device (3O2.i) is a licensed radio system operating in licensed bands. A secondary device (303. i) is any system/device operated in an unlicensed band. Each SARA device (301.i) maintains a Spectrum Opportunity Map (SOM) (200), which is populated by the SARAs (301.i) using the spectrum and by sharing SOMs (200) among SARAs (301.i). A SARA device (301/i) probes the medium for evidence of spectrum usage and may receive explicit information concerning spectrum usage from a primary (3O2.i) which it then records in its SOM (200) and may share its SOM (200) with other SARA devices (301.i). ® KIPO & WIPO 2008
