    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: Techniques are described for wireless communication. One method includes identifying a decoding status of one or more physical layer packets before inactivity on a secondary component carrier (SCC) in a shared radio frequency spectrum band; initiating an SCC reordering timer, wherein the SCC reordering timer is initiated when the decoding status of the one or more physical layer packets is identified as unsuccessful; and triggering a transmission, to a base station, of a radio link control (RLC) status report upon expiration of the SCC reordering timer. The RLC status report is transmitted before expiration of a RLC reordering timer initiated when the decoding status of the one or more physical layer packets is identified as unsuccessful. In some examples, the method may include resetting the SCC reordering timer when one or more additional physical layer packets are received on the SCC.

    Abstract translation: 技术描述为无线通信。 一种方法包括在共享射频频带中的次分量载波（SCC）上识别不活动之前的一个或多个物理层分组的解码状态; 启动SCC重新排序定时器，其中当所述一个或多个物理层分组的解码状态被识别为不成功时，启动所述SCC重新排序定时器; 以及在SCC重新排序定时器期满时触发无线电链路控制（RLC）状态报告给基站的传输。 当一个或多个物理层分组的解码状态被识别为不成功时，RLC状态报告在RLC重排序定时器期满前被发送。 在一些示例中，该方法可以包括在SCC上接收到一个或多个附加物理层分组时重置SCC重新排序定时器。

    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.

    Abstract: A method, an apparatus, and a processor-readable storage medium for wireless communication are provided. A transmitter transmits data packets to a receiver, encodes the data packets to generate parity packets, stores the parity packets in a retransmission buffer, receives information from the receiver indicating that a data packet was not correctly decoded, and transmits to the receiver the parity packets stored in the retransmission buffer for recovering the data packet not correctly decoded without retransmitting the data packet not correctly decoded. The transmitter may further retransmit to the receiver the parity packets. The transmitted data packets may be encoded at a medium access control (MAC) layer of the transmitter. The retransmission buffer may be located at a radio link control (RLC) layer or a packet data convergence protocol (PDCP) layer of the transmitter. A reordering buffer at the receiver may be located at the RLC layer or PDCP layer.

    Abstract: A user equipment (UE) may identify a bearer (e.g., a default bearer) and request establishment of a second bearer (e.g., a high priority bearer) for use in streaming downlink data from, for example, an application server. The UE may determine a status of a playout buffer and select the first bearer or the second bearer for use in streaming the downlink data associated with the application based on the status of the playout buffer. For example, the first bearer may be used be used by default, and the second bearer may be selected if the amount of data in the playout buffer does not satisfy (e.g., is below) a threshold. In some cases, each bearer may be associated with a transmission control protocol (TCP) port associated with a TCP connection. In some cases, each bearer may be associated with different Internet protocol (IP) address.
