Method and system for mapping channels into a convolutional encoded time division multiplex in the downlink. In a transmission system comprising a plurality of stations, each station transmits in at least one channel, forming a plurality N of uplink channels that are transmitted, at an uplink information bit rate Ru, towards a destination station. Said destination station transmits in at least one downlink channel at a downlink information bit rate Rd, in such a manner that the relation Rd = N*Ru is satisfied. The number of the uplink channels N varies as a function of a change in a convolutional code rd applied to the downlink channel (C d), so that N is an integer multiple of said variable convolutional code rd.

Méthode et système de mise en correspondance de canaux lors d'un multiplexage temporel codé par convolution dans la liaison descendante. Dans un système de transmission comportant une pluralité de stations, chaque station transmet dans au moins un canal, formant une pluralité N de canaux de liaison montante qui sont transmises, à un taux Ru de débit binaire d'information de liaison montante, vers une station de destination. Ladite station de destination transmet dans au moins un canal de liaison descendante à un taux Rd de débit binaire d'information de liaison descendante, de telle manière que la relation Rd = N *Ru est satisfaite. Le nombre de canaux N de liaison montante varie en fonction d'un changement dans un code convolutif rd appliqué au canal de liaison descendante d), de sorte que N est un multiple entier dudit code convolutif variable rd.
