Abstract:
1. A method for transmitting data packets via a radio interface of a mobile radio system, the method comprising the steps of: transmitting information, by a controlled unit of a first entity secondary to the control unit in a data link layer, via logical channels of the control unit serving as service access points, the information formed as a configuration message, wherein the configuration message includes information indicating which logical channels are to be mapped onto which transport channels serving as service access points for a bit transmission layer, indicating which set of transport formats predetermined for each of the transport channels and a set of permitted combinations of transport formats for all transport channels, with each transport format having a set of parameters determining transmission characteristics of the transport channel configured with the corresponding transport format, and indicating which one of transport formats are permitted for each logical channel and a value is predetermined as fixed for at least one of the parameters from the parameter set for transport formats for one of one logical channel, a plurality of logical channels and all logical channels; selecting a transport format, via the first entity, for each of the transport channels taking into account an assignment defined in the configuration message of one of transport formats to logical channels and the parameter value predetermined for each of the logical channels, such that a resulting combination of transport formats corresponds to one of the transport combinations defined as permissible; and transmitting the data packets, via the first entity, at the logical channels to the transport channels of a bit transmission layer assigned to each of the logical channels by the configuration message and initiating the transmission of the data packets via the radio interface.
