Abstract

Data packets are transmitted via a radio interface, wherein a control unit of a first entity transmits information via its logical channels serving as service access points in the form of a configuration message, with the configuration message including information about which logical channels are to be mapped onto which transport channels serving as service access points for a bit transmission layer. A set of transport formats are predetermined for each of the transport channels along with a set of permitted combinations of transport formats for all transport channels. Each transport format includes a set of parameters determining transmission characteristics of the transport channel configured with the corresponding transport format. The first entity selects a transport format for each of the transport channels, such that the resulting combination of transport formats corresponds to one of the transport combinations defined as permissible and wherein the first entity transmits the data to initiate the transmission of the data packets.
