1. A communication system for transmitting a plurality of payload data packets, comprising:

  • a base station;

    a plurality of operable mobile stations;

    communication links having variable transmission capacity for establishing virtual connections between the base station and the plurality of operable mobile stations, wherein each of the communication links occupies time slots of a radio channel for a data transmission;

    control data packets of a first type, each of which being transmitted from the base station via each of the virtual connections to each of the plurality of mobile stations and containing at least information on a partitioning of the radio channel into time slots;

    control data packets of a second type, each of which being transmitted via one of the virtual connections for controlling the virtual connection;

    control data packets of a third type, each of which being transmitted via one of the virtual connections and containing at least one payload data packet; and

    forward error control signals transmitted in association with at least one of the control data packets, with a forward error control signal for a control data packet of the first type exhibiting a redundancy that is equal to or greater than a redundancy of a forward error control signal for a control data packet of the second type, and a forward error control signal for a control data packet of the second type exhibiting a redundancy that is equal to or greater than a redundancy of a forward error control signal for a control data packet of the third type.
