Abstract
The present disclosure relates to a 5G or pre-5G communication system which will be provided in order to support a higher data transmission rate than in 4G communication systems such as LTE. A method at a relay node according to one example of the present invention is a hybrid automatic repeat request method at the relay node in a relay wireless communication system using a compress-and-forward (CF) scheme, and may comprise the steps of: when receiving data from a previous node, performing mesh quantization so as to have redundant information at the time of quantization for transmitting, to a next node, the data received from the previous node; transmitting to the next node by channel-coding only an amount transmittable to a channel set for transmitting to the next node from upper information among the quantized information; and when receiving negative acknowledgement (NACK) from the next node, retransmitting to the next node by channel-coding only an amount transmittable to the set channel among the other information which is not transmitted among the quantized information.
