METODO DE TRANSMISION ARQ HIBRIDO PARA LA TRANSMISION DE PAQUETES DE DATOS.

摘要

An ARQ transmission method in a communication system, wherein data packets comprising modulation symbols are transmitted based on an automatic repeat request and subsequently combined with previously received data packets. The symbols of the transmitted data packets are modulated in a mapping entity employing at least a first and second signal constellation. The method further comprises the step of obtaining the second signal constellation from the first signal constellation by exchanging a logical bit position and/or inverting a logical bit. The invention further relates to a corresponding transmitter and receiver.
