<p>Methods systems and devices are disclosed for providing data such as voice data for a voice service over flexible bandwidth carriers. Some embodiments include support for 12.2 kbps and/or 7.95 kbps AMR CS voice over flexible bandwidth UMTS (F UMTS) in particular. Some embodiments provide for keeping the information data rate for a flexible bandwidth carrier at least the same as that of a normal bandwidth carrier. For example one voice frame may still be mapped to a 20 ms time window upon transmission irrespective of a flexible bandwidth scaling factor N or chip rate divider Dcr in F UMTS. The tools and techniques provided may be implemented on mobile devices and/or base stations. Flexible bandwidths carriers may utilize portions of spectrum that may be too big or too small to fit a normal bandwidth waveform for a normal bandwidth carrier.</p> |
