Abstract:
A method for configuring a telecommunication system comprising a plurality of entities, said entities implementing a step for transmission of data transported on at least one physical channel, said at least one physical channel transmitting a transport channel composite and having a maximum physical rate, said transport channel composite comprising a plurality of transport channels, said data transmission step being preceded by a data processing procedure for each of said transport channels, said data processing procedure comprising at least one rate matching step, said rate matching step transforming a number of symbols before said rate matching step into a number of symbols after said rate matching step, said number of symbols after said rate matching step being obtained approximately by multiplying said number of symbols before said rate matching step by a rate matching ratio specific to each of said transport channels, whereinsaid method comprises a determining step in which at least one of said entities as a first entity determines a variation between the number of symbols after said rate matching step and the number of symbols before said rate matching step, for each of said processing procedures, based on a first parameter and a second parameter, said first parameter representing said rate matching ratio for each of said processing procedures, said second parameter representing said maximum physical rate for said transport channel composite, at least one transport format is defined for each transport channel, at least one transport format combination determines a transport format among said defined transport formats for each of said transport channels, each transport channel comprising at least one data block type, said data block type depending at least on said transport channel and a transport format of the transport channel concerned, each data block type defining a number of symbols of the concerned data block before said rate matching step, and said step of determining the variation between the number of symbols before said rate matching step and the number of symbols after said rate matching step comprises: calculating a temporary variation for each of said at least one data block type starting from said first and second parameters and said number of symbols before said rate matching step; correcting a temporary rate for said transport channel composite resulting from said calculated temporary variation for each of said at least one data block type, for said at least one transport format combination, so that said temporary rate does not exceed said maximum physical rate for said at least one transport format combination, said correction step being a global correction step; and determining final variations for said at least one transport format combination, a final variation being determined for each of said at least one data block type.
