1. A method for transmitting data in a radio communication system, comprising:
transmitting data in parallel from a transmitting station to a data-receiving station over at least two relay stations, each relay station receiving and forwarding the data;
generating requests for retransmission if it is determined that the received data is not sufficiently free of errors, the requests for retransmission being generated only at the receiving station;
transmitting the requests for retransmission from the receiving station through at least one of the relay stations; and
retransmitting the data from the transmitting station if a request for retransmission is received through the at least one relay station from the receiving station.
