Example3
SinceallunuseddownlinkslotsareavailabletothebusyHSU,theutilizationgraphsforthis
caseareverysimilartothoseofExample1andwewi ll notrepeatthemall.Themain
differenceisinthesectorutilization:
Figure10‐12:SectorUtilization‐Example2
ThedownlinkutilizationishigherthanforExample1,reflectingthefactthattheHBSmust
spendproportionallymoretimecheckingtheinactiveHSUs.
Similarly,theSectorrelativeHSUdownlinkutilizationishigherbythesameamount .
Example3
Inthiscase,wearedeliberately“starving”thebusyHSU,byallocatingitoneuplinktimeslot
anddividingtherestbetweentheinactiveHSUs.ThesituationisshowninFigure 10‐13.
