  • receiving at a Packet Data Convergence Protocol (PDCP) layer of a transmitting end a first data block from an upper layer of the transmitting end;

    generating a second data block including the first data block at the PDCP layer of the transmitting end;

    discarding the first data block present in the PDCP layer of the transmitting end if a certain period of time has passed; and

    indicating, from the PDCP layer, layer of the transmitting end, a Radio Link Control (RLC) layer of the transmitting end to discard a corresponding RLC data block if the second data block has already been transferred from the PDCP layer of the transmitting end to the RLC layer of the transmitting end.
