    摘要: 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.

    摘要: In a wireless network, a user equipment (UE) may support reflective quality of service (QoS), where QoS applied to uplink packets is implicitly derived from downlink packets. For example, when the UE receives a downlink packet that includes a reflective QoS (RQoS) indicator and a QoS flow identifier (QFI), the UE may apply the same QoS associated with the downlink packet to an uplink packet with one or more attributes that match the downlink packet. However, for a received downlink encapsulating security payload (ESP) packet that includes an RQoS indicator and a QFI, a modem cannot determine an uplink security parameters index (SPI) and downlink SPI pairing needed to enable RQoS because the uplink/downlink SPI pairing is known only by the upper layer. Accordingly, some aspects described herein enable the modem to learn uplink/downlink SPI pairings for ESP packets and thereby enable RQoS for ESP packets.

    摘要: 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.

    摘要: Aspects of the present disclosure provide example apparatus, methods, processing systems, and computer readable mediums implementing techniques for modifying a configuration of a radio bearer based on a request for quality of service (QoS) for a communication flow. In aspects, a user equipment (UE) receives a request for a QoS for a communication flow and maps the communication flow to a radio bearer based on a downlink map. The UE is configured to communicate over a number of radio bearers. The downlink map associates one or more communication flows to one or more of the number of radio bearers. The UE then modifies a configuration of the radio bearer based on the request for the QoS. During operation, the UE receives one or more downlink packets on the radio bearer and processes the one or more downlink packets according to the QoS.
