Abstract
A single receiver can collect multiple protocol data units at one time originating from different sources. While it can be desirable for higher priority protocol data units to be processed, loss of data unit portions can cause confusion to the receiver. Therefore, even if a higher priority protocol data unit transfers to the receiver while a lower priority data unit is being processed, the lower priority unit can be completed before processing the higher priority unit; thus, there can be a lower likelihood of confusion among protocol data units.

A method for managing protocol data unit communication in a wireless communication apparatus, the method comprising:
- identifying a start portion for an initial protocol data unit, wherein the initial protocol data unit is divided into a plurality of portions comprising the start portion and an end portion, and wherein the start portion includes information on how to reconstruct the plurality of portions;
- and
- until determining that the end portion for the initial protocol data unit has been collected, denying transfer of at least one subsequent protocol data unit;
- and
- ranking protocol data units of a group of protocol data units based on priority levels, wherein the subsequent protocol data unit is of a higher priority level than the initial protocol data unit.
