Abstract: Methods, systems, and devices are provided that may support signaling, such as a Signaling Radio Bearer (SRB), over a flexible bandwidth carrier. For example, an SRB rate for a SRB over for a normal bandwidth carrier may be identified. A Transmission Time Interval (TTI) may be determined for the SRB over for the flexible bandwidth carrier that facilitates a SRB rate of the SRB over the flexible bandwidth carrier that maintains at least the SRB rate for the SRB over the normal bandwidth carrier. The determined TTI may be utilized for the SRB over the flexible bandwidth carrier, which may help avoid increased call setup delay, increased latency for handover, etc. that may be introduced in flexible bandwidth carrier systems. Some embodiments may include reducing spreading factors, increasing transmission power, and/or concatenating multiple transport blocks with respect to the SRB over the flexible bandwidth carrier.

Abstract: Methods, systems, and devices for facilitating mobility between flexible bandwidth systems and other bandwidth systems are provided. These tools and techniques that provide mobility between different bandwidth systems may facilitate supporting circuit-switched (CS) services, such as CS voice services. Some embodiments provide for determining flexible bandwidth capable devices, such as user equipment. Some embodiments involve core network redirection where a core network may direct the handling of circuit-switched services when a flexible bandwidth system does not support the CS services. Some examples provide for radio access network determined handling of CS services when a flexible bandwidth system may not support the CS services. Some embodiments provide for transitioning to a flexible bandwidth system. Some embodiments provide for transitioning from flexible bandwidth systems to non-flexible bandwidth systems that have no support for some or all CS services, other flexible bandwidth systems, and/or systems that natively support CS voice services.

Abstract: Methods, systems, and devices for mobility management for wireless communications systems that utilize a flexible bandwidth carrier are provided. Some embodiments include determining and transmitting assistance information to one or more user equipment (UEs) to facilitate mobility management with respect to the flexible bandwidth carrier. Some embodiments include signaling flexible bandwidth carrier information to UEs including, but not limited to: UE-centric approaches, network-centric approaches, network-centric approaches with PLMN, SIB creation approaches, and/or application layer approaches. A flexible bandwidth carrier may involve a wireless communications system that may utilize portions of spectrum that may not fit a normal bandwidth. A flexible bandwidth carrier may be generated with respect to a normal bandwidth carrier through dilating, or scaling down, the time or the chip rate of the flexible bandwidth carrier with respect to the normal bandwidth carrier. Some embodiments may expand a bandwidth for a flexible bandwidth carrier.

Abstract: 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.

Abstract: Methods, systems, and devices for supporting voice communications in a wireless communications system are provided. Some embodiments utilize multiple code channels to transmit the voice frames. These embodiments include parallel multi-code embodiments, offset multi-code embodiments, and multi-user multi-code embodiments. Some embodiments utilize flexible carrier bandwidths systems that may utilize portions of spectrum that may not be big enough to fit a normal bandwidth waveform. Some embodiments transmit and receive a subset of subframes of voice frames received over flexible bandwidth code channels. In some embodiments, a subset of subframes based on a flexible bandwidth scaling factor of one or more flexible bandwidth code channels is transmitted. The receiver may decode the voice frame based on the received subset of subframes. An outer loop power control set-point may be adjusted to provide a predetermined frame error rate based on the number of transmitted subframes.
