ABSTRACT:
Disclosed is a method of link adaptation of a blind type using power offset and multi-codes transmission etc. through acknowledgements (ACK/NAK) in an ARQ System having a Hybrid type as a link adaptation method which can be applied in the ARQ having the Hybrid type in a wireless channel. The method of controlling an adaptation link of a blind type using power offset in an ARQ system having a Hybrid manner, the method includes the steps of transmitting data by an initial coding rate and/or an initial transmission power value to the receiving party; receiving a retransmission (NAK) request signal from the receiving party; and performing the data retransmission by increasing the transmission power and/or the number of multi-codes according to the retransmission (NAK) request.
