Abstract: Various aspects of the disclosure relate to delivering a limited amount of system information. For example, the delivery of system information may be divided into broadcasting a limited amount of the system information and using unicast signaling for delivery of the remaining system information. In some aspects, the delivery of a limited amount of system information may involve broadcasting a compressed PLMN ID list (e.g., broadcasting indications of PLMNs). In some aspects, the delivery of a limited amount of system information may involve broadcasting an indication of the version of system information that is valid for a cell. In some aspects, the delivery of a limited amount of system information may involve broadcasting multiple configurations of system information along with indications of each configuration. In some aspects, the delivery of a limited amount of system information may involve broadcasting compressed non-cell-related system information.

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: One or more selectively activated features needed at a device to use a network service may be identified. Authorization information and feature activation key(s) associated with features that the device has been authorized to activate may be obtained at the device. The feature activation key(s) may be used to activate and/or maintain activation of the authorized features that match the selectively activated feature(s) needed to use the network service. An authorization server may obtain a request to activate one or more selectively activated features of a device. The authorization server may verify that the selectively activated feature(s) are authorized to be used at the device based on an authorization agreement obtained at the authorization server. The authorization server may send proof that the device is authorized to use the selectively activated feature(s) and may send feature activation key(s) based on the authorization agreement in response to the request.

Abstract: Certain aspects of the present disclosure provide a method for confirming identity of a user equipment (UE) registered in both a wireless local area network (WLAN) and WWAN. A method is provided for wireless communications by a base station (BS). The method generally includes establishing communications with a first UE, wherein the UE is identified by a first set of one or more identifiers in a wide area wireless network (WWAN) and by a second set of one or more identifiers in a wide local area network (WLAN), and determining, based on the first and second set of identifiers, a UE connected to the WWAN and WLAN is the first UE.

Abstract: Certain aspects of the present disclosure provide techniques for determining a configuration for packet data convergence protocol (PDCP) duplication. Certain aspects provide a method for wireless communication. The method generally includes determining a PDCP duplication configuration corresponding to at least one of multi-connectivity (MC) or carrier-aggregation (CA) for communication of at least one bearer with a user-equipment (UE), wherein the determination is based on an indication corresponding to a link quality for the communication, and sending an indication of the determined configuration for the communication of the at least one bearer.

Abstract: Aspects of the disclosure relate to configuration of the Access Stratum (AS) security in communication networks. The AS security may be defined by security configuration information selected for a protocol data unit (PDU) session established for a user equipment (UE). The security configuration information may be selected by a network node within a core network based on one or more of the PDU session, device type of the UE, or Quality of Service (QoS) flow within the PDU session. The security configuration information may be provided to a radio access network (RAN) serving the UE for selection of an AS security configuration that is specific to the PDU session.

Abstract: Certain aspects of the present disclosure provide techniques for ordering a plurality of potential base stations to serve a user equipment on a supplemental uplink and providing random access channel (RACH) configuration parameters for each of the plurality of potential base stations to the user equipment. Certain aspects provide a method for wireless communication. The method generally includes communicating, by a user equipment (UE), with a first base station (BS) on a downlink on a first frequency band. The method further includes receiving, by the UE from the first BS, a list comprising RACH configuration parameters for each of a plurality of BSs. The method further includes selecting a second BS from the plurality of BSs based on an ordering of the plurality of BSs in the list and performing a RACH procedure with the second BS.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for discovering a controller function for wireless backhaul using cellular radio access technology (RAT) such as communications systems operating according to new radio (NR) technologies. For example, such a method may include connecting to a parent relay that provides connectivity to a controller function (CF) of a network, receiving, from the parent relay, information regarding at least one of: the CF or a radio access network (RAN) area covered by the CF, obtaining an identifier of the CF using the information, and connecting to the CF using the identifier.

Abstract: Aspects of the present disclosure provide methods and apparatus for improving UL-based mobility. As described herein, a UE may determine it has failed to decode a first keep alive (KA) signal during a wake period of a discontinuous receive (DRx) cycle and may extend the wake period to monitor for a second KA signal, in response to the determination. An access network controller may select, while a (UE) is currently served by a first transmit/receive point (TRP), a second TRP to serve the UE, configure the first TRP to transmit a first keep alive (KA) signal, in response to a chirp signal received from the UE, and configure the second TRP to transmit a second KA signal after the first KA signal transmitted by the first TRP.

Abstract: Aspects of the present disclosure provide methods and apparatus for beam selection in uplink-based and downlink-based mobility scenarios, for example, for new radio (NR) systems which can improve handover reliability, reduce handover frequency, and improve power efficiency. Certain aspects provide a method for wireless communications by a user equipment (UE). The method generally includes transmitting an uplink reference signal with an indication of a preferred downlink beam and receiving a downlink transmission based, at least in part, on the uplink reference signal.
