This disclosure relates generally to communication network, and more particularly to a system and method for processing data packets for transmission in a wireless communication network. In one embodiment, a method is provided for processing data packets for transmission in a wireless communication network. The method comprises dynamically creating a plurality of data packet discard groups (DPDG's), determining a plurality of simultaneously active data packet transmission protocol (DPTP) packet discard timers (DPDT's) corresponding to the plurality of DPDG's, and assigning each of the plurality of simultaneously active DPDT's to each of the plurality of DPDG's. Each of the created plurality of DPDG's comprises a plurality of data packets.
