MAC LAYER RECONFIGURATION IN A MOBILE COMMUNICATION SYSTEM

摘要

The present invention relates to method and apparatus for reconfiguring a MAC entity of a MAC layer of the apparatus receiving protocol data units from a mobile terminal via an uplink channel upon reconfiguration of the uplink channel. Further, the invention relates to methods and mobile terminals for triggering the transmission of a status report from at least one RLC entity configured for an uplink channel of a network element in a radio access network of a mobile communication system, as well as a method and terminal for configuring the MAC layer of the mobile terminal. In order to enable an efficient and fast generation of RLC status reports after an uplink channel reconfiguration the present invention suggests new mechanism to trigger the transmission of status reports upon uplink reconfiguration as well a new operation and configuration of radio access network elements and UEs upon uplink channel reconfiguration, in particular a transmission time interval (TTI) reconfiguration.
