Method for configuring a telecommunication system
View Patent ↗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.
