Abstract: Embodiments herein disclose methods and devices for managing data traffic on a receiver. A method disclosed herein includes detecting, by a receiver, at least one out of order radio link control (RLC) protocol data unit (PDU) in a plurality of RLC PDUs received from a transmitter, performing, by the receiver, a recovery action based on a Packet Data Convergence Protocol (PDCP) reordering time to recover the at least one out of order RLC PDU; and causing, by the receiver, an RLC layer to send a plurality of RLC service data units (SDUs) to a higher layer after the performing the recovery action, the plurality of RLC SDUs corresponding to the plurality of RLC PDUs.

Abstract: A method of enabling downlink (DL) flow control in a high speed packet access (HSPA) network is provided. The method includes detecting, by a user equipment (UE) radio link control (RLC) layer, at least one missing packet data unit (PDU) during a radio frequency (RF) outage in a dual subscriber identity module (SIM) dual standby (DSDS) operation, triggering, by the UE RLC layer, a status PDU indicating the at least one missing downlink PDU, transmitting, by the UE RLC layer, the status PDU to the HSPA network, and receiving, by the UE RLC layer, the at least one missing PDU, which is re-transmitted from a HSPA network RLC layer.
