Abstract: A method involves determining an estimated position of a mobile device within a region. Atmospheric data measurement stations are identified within the region. A geographical anomaly is identified within the region that physically intervenes between the mobile device and a first atmospheric data measurement station. Based on a positional relationship between the mobile device, the geographical anomaly, and the first atmospheric data measurement station, it is determined that atmospheric pressure measurements collected at the first atmospheric data measurement station should be conditionally used for determining a reference pressure estimate. The reference pressure estimate is determined using a plurality of atmospheric pressure measurements collected at the atmospheric data measurement stations and conditionally using the atmospheric pressure measurements collected at the first atmospheric data measurement station.

Abstract: Apparatus, methods, and computer-readable media for network coding for handover are disclosed herein. A base station (BS) transmits a first group of encoded packets to a first road side unit (RSU) over a first radio access network (RAN) interface. The BS initiates a handover procedure between the first RSU and a second RSU. The BS receives, from the first RSU, a release acknowledgment associated with the handover procedure and feedback associated with the first group of encoded packets. The BS transmits network coding level information to the second RSU over a second RAN interface based on the feedback. The network coding level information indicates a number of missing encoded packets within the first group of encoded packets for the second RSU to transmit to the UE. The BS transmits, to the UE, a second group of encoded packets associated with the number of missing encoded packets at the second RSU.
