A method for handling timers in a wireless communication system includes starting a Timer_Poll_Periodic timer for a Radio Link Control Acknowledged Mode (RLC AM) entity, performing a reset procedure for the RLC AM entity, and restarting the Timer_Poll_Periodic timerin response to the Timer_Poll_Periodic timer expiring prior to completion of the reset procedure. The claimed invention also specifies appropriate handling of eight other timers after an RLC reset or re-establishment in order to prevent the RLC AM entity from experiencing deadlock or reduction in quality of service.
