    Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a 4G/LTE device and via a 5G/NR base station, a first handover command message identifying at least one of a measurement configuration or a measurement gap for identifying a 2G/3G cell, wherein the first handover command message is associated with a 5G/NR to 2G/3G handover of the UE via 4G/LTE; transmit, to the 4G/LTE device and via the 5G/NR base station, a measurement report regarding the 2G/3G cell based at least in part on the measurement configuration and/or the measurement gap; and tune to the 2G/3G cell based at least in part on a second handover message, received from the 4G/LTE device via the 5G/NR base station, for performance of the call via the 2G/3G cell. Numerous other aspects are provided.

    Abstract: An UE transmits at least one UE configuration parameter to a base station comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The UE then receives a configuration from the base station based, at least in part, on the at least one UE configuration parameter transmitted to the base station. Additionally, a base station receives the at least one UE configuration parameter from a UE comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The base station then configures the UE using the at least one UE configuration parameter received from the UE.

    Abstract: Certain aspects of the present disclosure relate to methods and apparatus for providing broadcast information on supported and non-supported slices using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communication by a user equipment (UE) may generally include receiving signaling of at least one of: a first list of network slices indicated as available in a first cell or a second list of network slices indicated as unavailable in the first cell, and performing at least one of cell reselection or cell selection taking into account the network slices listed in the at least one of the first list or the second list.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive system information for a first cell on a second cell, wherein the UE is camped on the second cell, and wherein the system information for the first cell is received with system information for the second cell; access an uplink of the first cell using the system information for the first cell; and establish a connection on the first cell as a serving cell. Numerous other aspects are provided.

    Abstract: A technique is disclosed to minimize service interruption at a wireless user equipment device during a handover by maintaining dual active connections during the handover. Upon initiating the handover, an initial/first connection with a first access node is maintained while establishing a second connection with a second access node. The user equipment device can receive data over the first connection and second connection during the handover. The first connection may be terminated (by the user equipment device or by timing out due to inactivity) after the handover is completed. Other aspects, embodiments, and features are also claimed and described.

    Abstract: Techniques for secure control plane communications between a User Equipment (UE) and a gNB are provided. A RAN network entity decides to handover a UE from a source base station (BS) to a target BS, wherein the RAN network entity controls a plurality of BSs including at least one of the source BS or the target BS, and wherein at least a portion of a control plane (CP) protocol layer is implemented at the target BS. The network entity generates at least one key specific to the target BS, based on a master key and a freshness parameter, the master key associated with the network entity. The network entity transmits an indication of the at least one key to the target BS, wherein the target BS exchanges control signaling with the UE based on the CP protocol layer using the at least one key.

    Abstract: A gateway device detects a trigger associated with a device and, in response, identifies an application service associated with the device, obtains a traffic network policy associated with the application service, and obtains a network access token based on the traffic network policy. The network access token facilitates validating and/or mapping a downlink data packet obtained at the gateway device in user-plane traffic that is destined for the device. The network access token is sent to an entity in control-plane signaling. Subsequently, the gateway device obtains a downlink data packet including the network access token. The gateway device verifies the network access token and/or maps the downlink data packet to the device using data obtained from the network access token. The network access token may be removed from the downlink data packet before the downlink data packet is sent to the device according to the mapping.
