Abstract: A method for handling checksum error in uplink data compression (UDC) in a wireless communication system includes: detecting, by user equipment (UE), a checksum failure; automatically controlling, by the UE, generation of a number of compressed protocol data units (PDUs) available for transmission at a Packet Data Convergence Protocol (PDCP) based on a package formation rate (PFT); and transmitting, by the UE, a number of compressed PDUs.

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.
