Abstract: A method and system for configuring a CDMA telecommunications system having at least one sending entity and at least one receiving entity, each entity configured to transmit data on at least one physical channel (DPDCH) via a transport channel composite (CCTrCH) of multiple transport channels. At least one entity includes a data processing module configured to determine for each transport channel a first parameter (RMi) proportional to a rate matching ratio (RFi) and a second parameter representing a maximum physical rate (Ndata) and to transform for each of the transport channels a number of symbols before rate matching (Nk) into a number of symbols after rate matching (Nk+&Dgr;Nk), where the number of symbols after rate matching (Nk+&Dgr;Nk) is obtained approximately by multiplying the number of symbols before rate matching (Nk) by the rate matching ratio (RFi).

Abstract: The present invention relates to a method for selecting a combination of transport formats for a composite channel comprising at least two transport channels in a mobile station. The invention finds its application most particularly in third-generation mobile telecommunication systems (UMTS). To prevent the quality of service of certain applications from being considerably degraded when combinations of transport formats become temporarily invalid, there is provision to select according to the invention a combination of transport formats making it possible to guarantee a minimum bit rate for each logical channel of the mobile station.

Abstract: The present invention relates to a spread spectrum modulation using discontinuous spreading codes. The spectrum spreading codes used are sequences of chips wherein at least one chip has the value 0. These codes are called discontinuous spreading codes. Each of the chips with value 0 in the discontinuous spreading code generates a transmit power approaching zero for the corresponding transmitted signal.

Abstract: The subject of this invention is a method for matching transport channels included within a composite channel. Each transport channel transmits at least one data symbol (s). According to the invention, each symbol (s) to be transmitted is amplified by a gain (Gi) specific to the transport channel (i) from which said symbol (s) originates, in order to balance the Eb/I ratios between the different transport channels on the composite channel.
