A wireless communication device is described. The wireless communication device includes a memory and a processor in electronic communication with the memory. The processor is configured to determine a packet data convergence protocol (PDCP) packet count corresponding to a last radio link control (RLC) packet received in-sequence. The processor is also configured to detect a missing PDCP packet based on a comparison of the PDCP packet count and a sequence number of a last PDCP packet received in-sequence.

Layered missing packet detection

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information identifying a recovery time associated with packet data convergence protocol (PDCP) communication using a reordering timer, wherein a distribution of recovered PDCP counts associated with the PDCP communication is associated with a configured characteristic for a packet recovery time. The UE may communicate on a link using a communication configuration associated with a correlation between the packet recovery time and a link characteristic. Numerous other aspects are described.

Latency management for data traffic

Certain aspects of the present disclosure provide techniques for A method for wireless communication by a user equipment (UE), comprising initiating a timer upon reception of a first segmented packet of a plurality of packets of an RLC physical data unit (PDU) at radio link control (RLC) layer, resetting the timer when a packet data convergence protocol (PDCP) layer receives an RLC PDU from the RLC layer, and upon expiry of the timer, initiating a radio recourse control (RRC) connection reestablishment (RRE) procedure with a network.
