Abstract
Methods, systems, and devices are disclosed for providing services, such as voice services, within flexible bandwidth systems. In general, the scaling of one or more aspects of a flexible bandwidth system may be compensated for through altering one or more aspects within a code domain. The tools and techniques may include scaling spreading factors (with rate matching tuning in some embodiments), multi-code transmission, code rate increases, AMR codec rate adjustments, and/or higher order modulation. Subframe decoding approaches for the reception scheme may also be utilized. These tools and techniques can be flexibly implemented on the mobile device and/or base station side. Some embodiments may also minimize the latency introduced by the transmission and/or reception process. Flexible bandwidths systems may utilize portions of spectrum that may be too big or too small to fit a normal bandwidth waveform.
