Abstract: A data transmission method, a communication system, a transceiver, a transmitter and a receiver are described. In a data transmission method, a signal is transmitted between a first transceiver and a second transceiver, said signal being generated based on configuration parameters. A reconfiguration request signal is transmitted to said second transceiver. Said reconfiguration request signal is evaluated at said second transceiver. Said first transceiver is reconfigured based on a result of said evaluating to generate a further signal based on new configuration parameters different from said configuration parameters.

Abstract: According to a first aspect of the invention, a method for initializing a data transfer between a first communication device and a second communication device is provided, wherein said data transfer involves encoding and modulating data onto a plurality of carriers. A sequence of said carriers according to which the data is to be modulated onto said carriers which takes an encoding technique into account is calculated at said second communication device and transmitted to said first communication device, leading to a saving of memory. Furthermore, a method for adapting said data transfer is provided involving calculating changes to information concerning said data transfer in said second communication device and sending parameters indicative of the changes to said first communication device.

Abstract: A method and an apparatus for transmitting data is described. The data is modulated onto a plurality of carriers. At least one data element of the data is modulated onto at least two different carriers of the plurality of carriers. This technique presents an easy way to transmit data over carriers assigned to noisy channels as through combining the at least two different carriers the signal-to-noise ratio can be increased.
