<p>Apparatus and methods of data communication between a transmitter and a receiver in a radio link control (RLC) unacknowledged mode (UM) include determining, by the transmitter, a hyper frame number (HFN) de-synchronization condition, wherein the HFN de-synchronization condition is FALSE when at least one protocol data unit (PDU) out of a plurality of successive PDUs is successfully transmitted by the transmitter to the receiver, and wherein the HFN de-synchronization condition is TRUE when all of the plurality of successive PDUs are lost, and adjusting, by the transmitter, a transmitter HFN of the transmitter when the HFN de-synchronization condition is TRUE, wherein the adjusted transmitter HFN is used for new PDUs to be transmitted.</p> |
