Abstract
Several methods to avoid potential deadlocks in a SDU discard function are disclosed. First, the decision rule of deciding discarded SDUs in a SDU discard function is modified. Consideration of the Length Indicator is added to the decision of discarded SDUs in a SDU discard function to completely cover the SDU set that should be discarded. Secondly, the status-formatted padding PDU is chosen when padding PDUs is needed. Finally, modified explicit SDU discarding SUFI to cover scenarios that cannot be handled by the conventional MRW SUFI is utilized.

Abstract
This invention uses timers at the transmitter to track its sending data blocks to improve the timer-based stall avoidance mechanism of the prior art. Moreover, the invention uses a multi-timer mechanism to manage reordering buffers at the receiver. The multi-timer mechanism provides the receiver with one timer per reorder buffer, or uses one timer per missing data block, or uses one timer per missing data block but a gap of consecutive TSN missing data blocks can share one timer. The multi-timer mechanism can effectively track the missing blocks and monitor the reorder delivery process for all reordering buffers.
