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: Aspects of the present disclosure provide various techniques for requesting a system information block (SIB) and providing a SIB response for a user equipment (UE) in a UE-centric wireless communication network. In some aspects of the disclosure, the network may transmit the SIB to the UEs in a broadcast mode or in an on-demand mode.

Abstract: Capability exchange enhancements include filtering and/or indexing. In some aspects, a user equipment (UE) determines UE capabilities to be reported to a network based on one or more of: one or more enquiries from the network, received system information, a home operator policy, configuration associated with public land mobile network (PLMN) information of one or more networks, a user preference, or a service type. In other aspects, a UE may report a subset of UE capabilities for features used for the connection establishment. Following connection establishment, the UE may use an identifier to communicate a more complete set of modes of operation that the UE is currently capable of performing. Base stations of the network may share the reported subset so that the UE may avoid transmitting the subset to a target base station.

Abstract: Techniques are described that provide network assisted multi-subscription physical layer sharing at a user equipment (UE) by transmitting a multi-subscription coordination capability to a network, establishing a link for a first subscription with the network based on the multi-subscription coordination capability, and establishing a second subscription with the network using the link based on the multi-subscription coordination capability, the first subscription is associated with the second subscription.

Abstract: In an aspect, a network supporting client devices includes one or more network nodes implementing network functions. Such network functions enable a client device to apply a security context to communications with the network when the client device is not in a connected mode. The client device obtains a user plane key shared with a user plane network function implemented at a first network node and/or a control plane key shared with a control plane network function implemented at a second network node. The client device protects a data packet with the user plane key or a control packet with the control plane key. The data packet includes first destination information indicating the first network node and the control packet includes second destination information indicating the second network node. The client device transmits the data packet or control packet.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for multicasting traffic using multi-connectivity. A wireless network can send a downlink (DL) packet, which follows one path from a core network entity to a user equipment (UE) under current standards, to multiple base stations (BSs) and from each of the base stations to a UE. The UE receives the DL packet from whichever BS first delivers the DL packet, and then the UE sends a report reporting receipt of the DL packet back to all of the BSs. BSs that receive a report indicating the UE received the packet can drop the packet, even if they have not yet successfully delivered the packet. The same procedure can be used for an UL packet, which can be sent from a UE to multiple BSs, and from the BSs to a core network entity.

Abstract: Techniques are described for wireless communication. One method includes determining a portion of a transmission time interval (TTI) is available for a transmission that is shorter than a duration of the TTI; selecting a transmission format for transmitting the transmission to a receiving device during the portion of the TTI; and indicating a timing of the transmission to the receiving device. Another method includes determining a portion of a TTI is available for a transmission that is shorter than a duration of the TTI; selecting a transmission format from a plurality of transmission formats for transmitting the transmission to a receiving device during the portion of the TTI; and transmitting the transmission to the receiving device.

Abstract: An apparatus for wireless communication, including a memory and at least one processor coupled to the memory. The at least one processor is configured to receive a pre-allocation resource for a target cell via a handover command and transmit a physical layer acknowledgment based on a target cell downlink packet. The at least one processor is also configured to receive an indication for a communication with the target cell in response to the physical layer acknowledgement and access the target cell using the pre-allocated resource based on the indication for the communication with the target cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a dual connectivity configuration for a set of communication links, where at least one communication link of the set includes a sidelink. The UE may transmit a report based on an event associated with the sidelink that triggers the power headroom report. Additionally or alternatively, the UE may identify a carrier aggregation configuration for a set of communication links where at least one communication link of the set is a sidelink. The UE may determine an event associated with the sidelink that triggers a power headroom report, and transmit the power headroom report based on the determined event associated with the sidelink that triggers the power headroom report.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may autonomously initiate a handover procedure and select a target base station for the handover procedure. The UE may measure a signal from the source base station or the target base station, or both, and the UE may determine whether specific criteria at both base stations are within a pre-configured range. If the criteria at both base stations are within the pre-configured range, the UE may identify the target base station as a potential candidate for a handover. Accordingly, when the UE determines that radio conditions with the source base station are deteriorating (or fall below a threshold), the UE may initiate a handover to the target base station autonomously and without specific direction from the source base station.
