Method and system for mapping channels into a convolutional encoded time division multiplex in the downlink

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, so that N is an integer multiple of said variable convolutional code rd.
