SYSTEM AND METHOD FOR IMPROVING REORDERING FUNCTIONALITY IN RADIO COMMUNICATIONS

摘要

The definition and use of an additional timer for the MAC-hs reordering function in a user equipment. The timer counts transmission time intervals and is reset each time that the user equipment receives a data packet. If the timer reaches a set value, indicating a sufficiently long period of inactivity, then the transmission sequence number is reset to zero or another predefined value. A base station can run a similar timer and, after the timer reaches a set value, can consider the user equipment as no longer being active.
