Abstract
A method for management of data flow at a receiver includes receiving, in a reordering window of a PDCP layer, a plurality of data packets each including header information, and determining, based on the header information, packet sequence numbers of the received data packets, flow IDs each associated with a corresponding data packet of the received data packets, and at least one packet flow sequence number of each of the flow IDs, determining, based on the determined flow IDs and the at least one packet flow sequence number of each of the determined flow IDs, a set of data packets of which associated packet flow sequence numbers are in order with respect to the flow IDs, and transferring the determined set of data packets to an upper layer based on determining that the reorder timer of the PDCP layer is running.
