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 provided that may address problems pertaining to effective transmit power control of a communications device operating in a wireless communications system. Some embodiments utilize mechanisms or techniques with dynamically adaptive steps sizes for transmit power control based on one or more trends. Some of these techniques may identify a trend in the transmit power control (TPC) commands and may adapt a TPC step size as a result. Other techniques may be utilized in which transmit power control is based on multiple interference estimates in a frame slot. Having multiple interference estimates at sub-slot intervals may provide additional transmit power control by allowing more transmit power adjustments, or more appropriate adjustments, for each slot. Metric calculations may be performed on one or more techniques to determine appropriate TPC operations.

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.
