    Abstract: Techniques described herein are directed toward enabling location support for 5G New Radio (NR) wireless access by a user equipment (UE) by utilizing existing LTE location support. More specifically, LTE positioning protocol (LPP) messages may be communicated between a UE with NR wireless access and a location server (e.g. an LMF) in a 5G Core Network via an NG-RAN. The LPP messages may support RAT-independent and E-UTRA position methods by the UE such as A-GNSS or OTDOA for E-UTRA. The location server may obtain OTDOA related information from eNBs and ng-eNBs supporting LTE wireless access. A UE may request measurement gaps from a 5G base station (e.g. gNB) in order to obtain measurements for RAT-independent and E-UTRA position methods and may request an idle period in order to obtain LTE timing needed for E-UTRA measurements.

    Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive, at a central unit of the receiving device, information from which the central unit is able to identify a hash calculated based at least in part on a data portion of a message received by a distributed unit of the receiving device. The receiving device may confirm, at the central unit and based at least in part on the hash, an integrity of the data portion of the message. Additionally or alternatively, a distributed unit of the receiving device may confirm the integrity of the data portion of the message. The receiving device may authorize, based at least in part on the integrity confirmation, one or more user plane tunnels with the distributed unit to forward the data portion of the message from the distributed unit to the central unit after processing at the distributed unit.
