Abstract: A method includes monitoring, at an upper layer of the UE, PDU activity for one or more PDU sessions that are associated with one or more DNNs. The method includes determining that each of the one or more PDU sessions has a period of inactivity based on at least one of an expiration of an activity check timer, accumulated inactivity cycles, or a dormancy indication associated with each of the one or more PDU sessions. The method includes indicating, to a lower layer of the UE, to provide UE assistance information to a base station for a RRC connection release between the UE and the base station.

Abstract: This disclosure provides systems, methods, and apparatuses for sharing a maximum transmit power limit between a first radio access technology (RAT) and a second RAT. In one aspect, a wireless communication apparatus may reduce the maximum transmit power limit of a first uplink signal associated with the first RAT to obtain a first transmit power. The wireless communication apparatus may allocate a second transmit power remaining from the maximum transmit power limit to a second uplink signal associated with the second RAT. The wireless communication apparatus may reduce the maximum transmit power limit when the wireless communication apparatus is located at a cell edge, and a higher priority of the first RAT in relation to the second RAT may otherwise result in the second transmit power of the second uplink signal not satisfying a threshold.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for tracking network traffic for local area network (LAN) subnets in a wireless wide area network (WWAN). In some implementations, a UE of the WWAN may assign a unique public IP address to each router of the LAN. The UE may transmit network traffic received from the LAN to the WWAN. The network traffic originating from any router of the LAN may be associated with the unique public IP address that was assigned to that router. The WWAN may use the unique public IP addresses to generate network traffic information that may indicate amounts of network traffic flowing from each router of the LAN. The WWAN, for example, may use the network traffic information to determine billing information for any router in the LAN.

Abstract: Certain aspects of the present disclosure provide techniques for reporting an indication of a PHR when the UE's assigned of UL resources is insufficient to transmit both UL data and a PHR. Additionally, aspects described herein introduce a negative PHR used to indicate the UE requires additional UL resources.

Abstract: Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a user equipment (UE) to select a data connection based on which applications are active in a foreground process of an application processor. The UE may activate a dedicated data subscription (DDS) based on a list of active applications. In some aspects, the UE may programmatically initiate a DDS switch based on which applications are active. The UE may determine which data connection to activate as the DDS based on the application configuration information and which applications are active. Application configuration information may indicate preferences regarding different data connections to use for each application. The application configuration information may indicate a preferred radio access technology (RAT), a preferred communication network, a preferred subscription, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station according to a first radio access technology (RAT) in a first frequency range. The UE may perform measurements on a set of candidate cells of a second RAT or a second frequency range based on a determination for the UE to operate according to the second RAT or the second frequency range. The UE may perform a mobility procedure to establish a connection with a first cell of the set of candidate cells based on a determination that a first value of a first measurement parameter for the first cell satisfies a first threshold, and further based on a comparison of a different, second value of a second measurement parameter for the first cell to a second threshold.

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 communications are described. A user equipment (UE) may establish a cellular connection with a base station associated with a cellular radio network. The UE may receive an access policy of the cellular radio network identifying an access preference rule for the UE to adopt for connections to a core network function of the cellular radio network, the access preference rule indicating for the UE to preferentially connect to the core network function via a non-cellular radio network. The UE may determine that a gateway between the non-cellular radio network and the core network function of the cellular radio network is not configured. The UE may determine that a gateway selection policy of the cellular radio network is not configured. The UE may establish a connection to a legacy core network function of a legacy cellular radio network via a legacy gateway.

Abstract: Various aspects of the disclosure relate to handover of a user equipment (UE) between a standalone mode of operation and a non-standalone mode of operation. For example, a UE may be handed-over from standalone to non-standalone, or vice versa. Moreover, this handover may be an inter-system handover (e.g., between an LTE core network and an NR core network).
