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: A Location Management Component (LMC) may be included in a gNB and connected to a gNB Central Unit (gNB-CU). The gNB-CU receives location related messages from any of (i) a UE via a gNB Distributed Units (gNB-DU), (ii) another gNB via an Xn interface, or (iii) a core network entity (e.g. AMF) via an NG interface. These messages can be transported in container messages (e.g., an RRC container for LPP messages sent to or received from a UE; an NGAP container for messages sent to or received from an AMF, or an XnAP container for messages sent to or received from another gNB). The gNB-CU removes the location related messages from the container messages and forwards them to an LMC using F1-AP container messages. Location related messages sent from an LMC to other entities are transported in a reverse manner through a gNB-CU using corresponding container messages.

Abstract: Improvements are provided to the paging process for an eMTC UE by allowing a base station and the UE to apply a UE-specific DRX cycle for paging, from one set of DRX cycles, when the UE is operating in non-CE mode and apply another UE-specific DRX cycle, from a more restricted set of UE-specific DRX cycles, when the UE is operating in a CE mode. A UE may report and apply certain UE-specific DRX cycles under non-CE mode, and may change a UE-specific DRX cycle to one from a more restricted set when operating in CE mode. Similarly, base stations may receive the reported UE-specific DRX cycle and apply that UE-specific DRX cycle for paging the UE in non-CE mode, while applying a different UE-specific DRX cycle from the more restrictive set for paging the UE in CE mode.

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.

Abstract: Generally, the described techniques provide for a core network signaling to a base station a delay budget configuration that indicates a determined latency for communications between a core network, base station, and a user equipment (UE). In some cases, the core network may determine a first variable delay budget between the core network and a base station based on capability information associated with the wireless communications system. The core network may transmit the delay budget configuration to the base station, where the delay budget configuration may include the first delay budget. The base station may be able to determine a delay between the UE and the base station based on the delay budget configuration. Using the delay budget configuration, the base station may then schedule communications with the UE.

Abstract: Techniques and apparatus for supporting flexible radio access network (RAN) node identifiers in a network are provided. In one technique, a cell identity of a cell associated with a base station in a network is determined. An identifier of the base station is determined from the cell identity based on a partitioning of an identifier space used for identifying cells in the network. A message that includes at least one of the identifier of the base station or the cell identity associated with the base station is transmitted. In another technique, a user equipment may determine whether to take one or more actions while transitioning from operating in an inactive mode to operating in a connected mode based on the identifier of the base station.

Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) to report packet switched voice call capabilities to a base station. The UE may explicitly report voice call capabilities via one or more system-level parameters that are transmitted to the base station. The base station may operate in a first radio access network (RAN), such as a 5G or new radio (NR) RAN. In cases where the UE indicates a capability for packet switched voice calls via the first RAN, one or more voice calls may be established with the UE via the first RAN. In cases where the UE indicates that it is not capable of packet switched voice calls via the first RAN, the UE may fall back to a different RAN (e.g., a 4G or LTE RAN, a 3G RAN, or a 2G RAN) for voice calls.

Abstract: Aspects encompassing public land mobile network (PLMN) configurations are disclosed. In one example, first and second PLMN configurations are determined, and a parameter having a common identifier between a hybrid PLMN and a PLMN from a different PLMN configuration is identified, such that the hybrid PLMN may connect with a first or second core network type. Inclusion of the common identifier is limited to either the first or second PLMN configuration via an index, and the first and second PLMN configurations are transmitted. In another example, first and second PLMN configurations are received, and a hybrid PLMN in one of the two PLMN configurations is selected. A determination is made whether to use the hybrid PLMN to connect with a first or second core network type. Whether a hybrid PLMN parameter was ascertained via the first or second PLMN configuration is reported. Other aspects, embodiments, and features are also included.

Abstract: A method of wireless communication by a user equipment (UE) without a radio resource control (RRC) connection to a base station includes receiving system information from the base station and transmitting a data communication to the base station over a control plane without establishing an RRC connection with the base station. A UE in an RRC suspended state may transmit a data communication to the base station over a user plane without resuming an RRC connection with the base station. The data communication may comprise data and UE identity information and/or a cause indication. A base station may indicate resources in the system information for the transmission of the data communication information and receive the data communication over the control plane without establishing an RRC connection with the UE or over a user plane without resuming an RRC connection with an RRC suspended UE.
