Abstract: A user equipment may identify one or more trigger factors associated with an assistance mode. The assistance mode may include a second radio associated with a second radio access technology (RAT) assisting a first radio associated with a first RAT. The UE may then measure a frequency offset between a first clock of the first radio and a second clock of the second radio based at least in part on the one or more trigger factors. The first clock may be associated with a first oscillator crystal, and the second clock may be associated with a second oscillator crystal. The UE may then store the frequency offset for use by the first radio and the second radio in the assistance mode.

Abstract: An apparatus for wireless communication obtains a first metric of a cell based on signals received by a WWAN radio tuned to a common frequency, and a second metric of the cell based on signals received by a WLAN radio tuned to the common frequency. The apparatus determines a calibration factor based on the first and second metrics, and performs cell search and cell measurement based on the calibration factor and signals received by the WLAN radio tuned to a target frequency. The common frequency may be a serving frequency of the WWAN, in which case the first and second metrics are one of frequency or power metrics and the calibration factor is one of a frequency offset and a power offset. The common frequency may also be a target frequency for inter-frequency measurements of the WWAN, in which case the calibration factor is based primarily on power measurements.

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 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.

Abstract: Systems and techniques are described for sidelink synchronization source selection. For example, a method for wireless communications at a user equipment (UE) may include transmitting, from the UE to a target UE, a message including information associated with a first synchronization reference source associated with the UE. The method may include receiving, at the UE from the target UE in response to the message, a response message including an indication of whether the target UE can use the first synchronization reference source for sidelink positioning. The method can further include determining, at the UE based on the response message, whether to use the first synchronization reference source or a different synchronization reference source as a master synchronization reference source for the sidelink positioning.
