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 base station (BS) 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a master node (MN) may receive an acknowledgment message from a secondary node (SN). The MN and the SN may provide dual connectivity with a core network for a user equipment. The MN may provide an address indication message to the SN. The address indication message may include MN downlink transport network layer (TNL) information for an SN terminated data radio bearer (DRB) that requires master cell group (MCG) resources. The address indication message may be provided in a first message that immediately follows the acknowledgment message. In some aspects, the SN may receive the address indication message, and may forward, based at least in part on the MN downlink TNL information, downlink data for the SN terminated DRB that requires MCG resources. Numerous other aspects are provided.

Abstract: Methods for performing a handover in wireless communications for a user plane function (UPF) are disclosed. In an aspect, the method includes establishing a tunnel between the UPF and a target base station based on information in a path switch preparation request for a make before break handover of a user equipment (UE) from a source base station to the target base station, the path switch preparation request being received in response to a request originating by the target base station. The method further includes bi-casting a downlink data packet unit (PDU) to a source base station and to the target base station with a same sequence number (SN) in a tunnel protocol, receiving PDUs from the source base station and the target base station with corresponding PDUs having the same SNs in the tunnel protocol and discarding received duplicate PDUs based on the SNs in the tunnel protocol.

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: Wireless communications systems and methods related to globally unique temporary identity (GUTI) reallocation for cellular-Internet of thing (CIoT) are provided. A user equipment (UE) receives, from a network, a paging associated with a mobile-terminated early data transmission (MT-EDT). The UE transmits, by the UE to the network, a data request in response to the paging. The UE receives, from the network in response to the data request, a message including a global unique temporary identifier (GUTI) and at least one of data associated with the paging or a connection release indication.

Abstract: A method of wireless communication is presented. The method includes receiving, at a user equipment (UE) operating on an authorized shared access (ASA) spectrum, an inter-frequency measurement report from a wireless device operating in a specific area and operating on a spectrum that is different from the ASA spectrum. The method also includes receiving, at the UE from a network controller, a transmission adjustment request based at least in part on the measurement report. The method further includes adjusting, at the UE, a transmission based on the transmission adjustment request and/or the measurement report.
