Overhead of fast sensing in network’s transmission data rate (3/3) 2/3/2010 Ns-2 Module for IEEE 802.22 Standard 18
802.22 Inter-Cell Synchronization • Synchronization of QPs for better detection of primary users with inter-cell beacons – E.g. two overlapping BSs, BS 1 and BS 2 . BS 1 sends an inter-cell beacon to BS 2 . BS 2 tries to slides frames with the following rule: • If (FDC – O + O T ≤ ceil (FDC/2) x Rv ), slide frames right by FDC – O T x + O R v • Else slide frames left by (O T x - O R v ). • FDC: Frame Duration Code (time duration) Source: Bian, K. and Park, J. 2008.
