Abstract: Techniques described herein include utilizing a mobile device as a proxy receiver for a vehicle such that a driver of the vehicle can be presented driving assistance information based on messages received by the mobile device. The mobile device can determine that it is temporally located with the vehicle. If so, the mobile device can be configured to receive messages from other entities (e.g., vehicles, roadside units, traffic signals, and the like) in a vehicle-to-everything network. On reception, the mobile device may determine whether a received data message is relevant to the vehicle. In response to determining that the data message is, in fact, relevant to the vehicle, the mobile device may provide driving assistance information that is generated based at least in part on the information provided in the received data message.

Abstract: Techniques described herein provide for filtering and prioritizing incoming messages, which can help reduce and smooth out the processing load on components used to process the incoming messages. Filtering techniques may comprise identifying a subset of nearby vehicles from which messages are to be processed, and further calculating remaining delay budgets with regard to the messages to prioritize them for processing. Different techniques for determining a subset of nearby vehicles can be used, and/or remaining delay budgets may be calculated and/or communicated in different ways.

Abstract: The present disclosure describes various techniques to provide network access to a user equipment by using network infrastructure and/or wireless spectrum from an asset operator. In an aspect, a network device associated with the asset operator may receive a request for wireless wide area network (WWAN) access for a UE. The network device may identify the UE as a subscriber of an operator based at least in part on the request, where the operator is different from the asset operator, and where the network device is configured to provide WWAN access to subscribers of the operator via a core network associated with the operator based at least in part on a services agreement between the operator and the asset operator. The network device may then provide WWAN access to the UE in response to identifying that the UE is a subscriber of the operator.

Abstract: An apparatus for capturing a signal of interest, e.g., PSS and/or SSS, captures data transmitted by a first RAT by obtaining access to a receive chain for a second RAT during a measurement gap for the first RAT. The signal of interest transmitted by the first RAT is captured during the measurement gap using the receive chain for the second RAT. Access to a receive chain for the second RAT may be obtained in any one of several ways. For example, access may be obtained by 1) requesting receive chain access for the second RAT for LTE measurements through a virtual flow, 2) entering into a power save mode, 3) tuning to a non-operating channel, 4) setting network allocation vector (NAV) at or above a threshold value, or 5) entering a measurement mode during which the receive chain for the second RAT is prevented from performing WLAN operations.

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.

Abstract: Methods, systems, and devices are provided that may support paging over a flexible bandwidth carrier. For example, a reduced paging capacity with respect to a target paging capacity for the flexible bandwidth carrier may be identified. The reduced paging capacity for the flexible bandwidth carrier may be mitigated by various techniques. One technique may include increasing a number of paging indicators sent per frame over the flexible bandwidth carrier. Other techniques may include reducing a Spreading Factor (SF) for a physical channel or a Secondary Common Control Physical Channel (SCCPCH) carrying the paging indicators over the flexible bandwidth carrier. Further techniques may include utilizing a plurality of paging channels, which may include utilizing a plurality of Paging Indicator Channels (PICHs) or a plurality of SCCPCHs. Other techniques may include reducing a paging area for at least the flexible bandwidth carrier and a normal bandwidth carrier.

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.
