ADAPTIVE FLEXIBLE BANDWIDTH WIRELESS SYSTEMS

摘要

Methods systems and devices are described for providing flexible bandwidth waveforms and channels for wireless communication. Embodiments may utilize portions of spectrum that may not be large enough to fit a standard or normal waveform. Chip rates may be adapted dynamically to generate and/or to receive flexible bandwidth waveforms to fit these portions of spectrum. Scaling factors and/or center frequencies may also be utilized to generate flexible waveforms. A mobile device may receive adjustment information from a base station so that the mobile device may dynamically adjust its chip rate to utilize a flexible bandwidth channel. A base station may simultaneously transmit on a normal bandwidth channel and a flexible bandwidth channel in some cases. Some flexible bandwidth waveforms may be utilized that are larger or take more bandwidth than a normal waveform. Flexible bandwidth may also be utilized to split and/or combine frequency channels.
