Abstract:
1. A method for transmitting data from a base station to a destination, comprising: transmitting the data from the base station to both the destination and a relay station within a first transmission; decoding the data in the first transmitting at both the relay station and the destination wherein the destination acknowledges success of the decoding by generating a ACK message or lack of success by generating either a NACK message or by failing to generate the ACK signal; retransmitting from the base station information related to the first transmission in response to either the NACK message or the failure of the destination to generate the ACK message; and wherein when the relay station decodes the data sent by the base station within the first transmission correctly, the relay station transmits a second transmission; or, on the other hand, if the relay station is unable to decode the data correctly from the first transmission sent by the base station, the relay station remains silent.
