PARAMETER SCALING FOR FRACTIONAL BANDWIDTH 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. |
