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: The present disclosure provides systems, methods, and apparatuses for maintaining continuity of a buffer status report (BSR) from a user equipment (UE) when the UE is handed over between base stations. In one aspect, a base station or a component thereof may be configured to allocate a set of resources for transmission by a UE. The set of resources may have a capacity that is insufficient for an amount of data indicated by a BSR from the UE. The base station or component thereof may be further configured to transmit, to another base station in association with handover of the UE, an indication that the capacity of the set of resources is insufficient for the amount of the data indicated by the BSR.

Abstract: Disclosed are techniques for wireless communication using satellite access to a wireless network, where a wireless cell supported by a satellite is moving or temporarily fixed. In an aspect, a radio access network (RAN) entity or a user equipment (UE) provides, to a core network entity, an enhanced cell global identifier (CGI), where the enhanced CGI includes at least one field representing a location of the UE. Based on the enhanced CGI, the core network entity determines a location of the UE, and may provide a service to the UE based on the location. A core network may also provide an enhanced CGI to a RAN, e.g., to support wireless emergency alerting to UEs.

Abstract: Wireless communications systems and methods related to communications in a wireless network during handover are provided. A method of wireless communication performed by a first base station (BS), may include communicating, based on a handover condition, flight path information associated with an unmanned aerial vehicle (UAV) and performing a communication handover of the UAV between the first BS and a second BS.

Abstract: Wireless communications systems and methods related to mobility with consideration for network slicing are provided. In one embodiment, a user equipment (UE) transmits in a first cell frequency of a network, a request for a network slice of the network that is not provided by the first cell frequency. The UE receives, in response to the request, an information for communicating in a second cell frequency of the network that provides the requested network slice. In one embodiment, a core network entity receives, from a network entity operating over a first cell frequency of a network, a request to provide a network slice of the network to a UE, the network slice not provided by the first cell frequency. The core network entity transmits, to the BS, information associated with a second cell frequency of the network providing the network slice.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may truncate or remove a number of bits from its UE identity based on identity truncating information to generate a truncated UE identity. The truncated UE identity can be transmitted by eMTC devices to a base station in an RRC connection request, and can be used by the base station to determine which core network entity stores the UE's capabilities. In some implementations, the UE may truncate or remove a number of bits from the 48-bit 5G-S-TMSI based on the identity truncating information to generate a 40-bit truncated 5G-S-TMSI that can be transmitted by an eMTC device to the base station in the RRC connection request and yet still provide the base station with enough information to determine which AMF stores the UE context.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may transmit, to a second node, a first message providing a first indication of integrated access and backhaul (IAB) capability. The first node may receive, from the second node and in response to the first message, a second message providing a second indication of IAB capability. The first node may establish an IAB capable connection with the second node based at least in part on the first message and the second message. Numerous other aspects are provided.

Abstract: Techniques are described to support call routing and location for a user equipment (UE) with satellite wireless access to a serving PLMN. The UE sends a Session Initiation Protocol (SIP) INVITE message to a network node, such as a P-CSCF, that includes an indication of satellite access for the UE. In response the network node sends a request to another network node for a cell ID for a fixed cell in which the UE is located. The fixed cell can be independent of satellite radio cells for the serving PLMN. The network node may receive the cell ID for the fixed cell and sends the SIP INVITE message to another network node (e.g., an E-CSCF or LRF) with the cell ID for the fixed cell. The other network node may use the cell ID to route the SIP INVITE message or obtain an approximate location of the UE.
