The invention relates to a method for configuring a telecommunication system comprising at least one sending entity and one receiving entity between which the same link transmits several transport channels with different qualities of service. The sending entity matches the rate between the different coded transport channels with separate qualities of service, and the different coded transport channels are then multiplexed. The matching rate specific to each coded transport channel is determined from at least one first parameter representative of the expected Eb/I ratio and a second parameter representative of the capacity of the physical channel.

Method for configuring a telecommunication system

A method and system for configuring a CDMA telecommunication 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 bit 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+&#x394;Nk), where the number of symbols after rate matching (Nk+&#x394;Nk) is obtained approximately by multiplying the number of symbols before rate matching (Nk) by the rate matching ratio (RFi).

This invention relates to a communication apparatus and method for a code division multiple access communication system transmitting a transport channel composite including data of transport channels between a base station and a communication terminal via a physical channel, the physical channel having a maximum physical rate and rate matching is performed on data of each of the transport channels to change a transmission rate.

This invention relates to a method for rate matching between at least two transport channels included within a composite channel. An object of this method is to minimize the number of the DTX symbols inserted the composite channel. This method comprises a rate matching step for each transport channel (i), a rate matching ratio (RF) being applied to each transport channel. The inventive method comprises a step () for defining, for said composite channel, a ordered list of transport channels, a step () for determining at least two so-called global intervals for said ordered list of transport channels, and a step () for assigning a scale factor (LF) to each determined global interval.
