Abstract: Methods, systems, and devices for wireless communication are provided for mobility management for wireless communications systems that utilize a flexible bandwidth carrier. Some embodiments include approaches for determining bandwidth information, such as one or more bandwidth scaling factors N and/or flexible bandwidths, at a user equipment (UE), where the bandwidth information may not be signaled to the UE. Embodiments for determining bandwidth information include: random ordered bandwidth scaling factor approaches, delay ordered bandwidth scaling factor approaches, storing bandwidth scaling factor value in UE Neighbor Record approaches, spectrum measurement approaches, spectrum calculation approaches, and/or a priori approaches. Flexible bandwidth carrier systems may utilize spectrum portions that may not be big enough to fit a normal waveform. Flexible bandwidth carrier systems may be generated through dilating, or scaling down, time, frame lengths, bandwidth, or the chip rate of the flexible bandwidth carrier systems with respect to a normal bandwidth carrier system.

Abstract: Apparatus, methods, and computer program products providing power savings in Semi-Persistent Scheduling (SPS)-configured Voice over Long Term Evolution (VoLTE) with Connected State Discontinuous Reception (C-DRX) are provided. The apparatus may be a user equipment (UE). The UE receives a packet when the UE is in a persistent scheduling mode. The UE transmits a negative-acknowledgement (NACK) message when the packet is not successfully decoded. The UE refrains from transmitting an acknowledgement (ACK) message when the packet is successfully decoded. The UE may enter a power save state immediately after the packet is successfully decoded. The packet may be addressed to the UE in a unicast message. The packet may be received during an on-duration of a C-DRX cycle. The packet my include VoLTE downlink (DL) traffic. The packet may be received on a physical downlink shared channel (PDSCH).

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The method and apparatus resolve issues related to voice and data handovers between micro cells, femto cells and other small cells, and to handovers from macro cells to small cells are becoming increasingly significant as small cells are more widely deployed. In order to handoff a call associated with a user equipment, a base station attempts to identify neighboring cells that are within communication range of the user equipment based on a primary scrambling code and delays between multiple transmissions of the PSC detected by the user equipment and reported to the base station by the user equipment.

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.

A user equipment (UE) may receive, over a first frequency band, a first vehicle safety message indicating location information of a second wireless device. The UE may perform, with the second wireless device over a second frequency band that differs from the first frequency band, a beam sweeping procedure using a first subset of beams from a plurality of available beams to determine one or more beams of the first subset of beams to be used for communication with the second wireless device, each beam of the first subset of beams being oriented at least partially in a direction corresponding to the location information of the second wireless device. The UE may communicate, over the second frequency band, one or more messages with the second wireless device used the one or more beams of the first subset of beams.
