    Abstract: Wireless communication methods, devices, and systems to reduce latency when network access (e.g., cellular network access) is barred are described. A method includes receiving, by a user equipment (UE) from an application, a request for at least one of establishment of a packet data unit (PDU) session or uplink (UL) data transfer via a previously established PDU session. The method additionally includes evaluating that access to a first network (e.g., a 3rd Generation Partnership Project (3GPP) network) is barred. The method also includes determining that the access barring time exceeds a threshold, and checking, in response to the determining, that configured policies permit the PDU session to be on a second network (e.g., a non-3GPP network). The method further includes transferring data of the PDU session in accordance with the configured policies. Other aspects and features are also claimed and described.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus transmits, by a user equipment (UE), a packet to a network entity, while the UE is in a radio resource control (RRC) connected mode. The apparatus determines an acknowledgment (ACK) is absent for the transmitted packet. The apparatus determines to retransmit the packet based at least on whether the UE is in the RRC connected mode or on a type of the packet, upon determining the ACK is absent. The apparatus may determine to retransmit the packet by retransmitting the packet upon determining the UE is in the RRC connected mode. The apparatus may determine to retransmit the packet by suppressing retransmission of the packet upon determining that the UE is not in the RRC connected mode.

    Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for updating QoS configurations at a user equipment (UE). An example method generally includes receiving, from a network entity, quality of service (QoS) information, a QoS identifier associated with the QoS information, and a bearer context associated with the QoS information in one of a modify bearer context request message, an activate default bearer context request message, or an activate dedicated bearer context request message; and updating a QoS configuration using the QoS information based on whether the UE is already configured with QoS information associated with the QoS identifier for a bearer context different from the bearer context associated with the QoS information received in the modify bearer context request message, activate default bearer context request message, or activate dedicated bearer context request message.
