Abstract:
1. A data transmission method using a hybrid automatic repeat request (HARQ), the method comprising: transmitting, by a device, a first transmission block which is a portion of bit streams of a mother codeword; receiving, by the device, a retransmission request with respect to the mother codeword; and transmitting, by the device, a second transmission block which is a bit stream subsequent to the first transmission block according to the retransmission request, wherein a modulation order obtained from a first range of a modulation order product code rate (MPR) is applied to the first transmission block, wherein a modulation order obtained from a second range of the MPR according to a number of retransmissions is applied to the second transmission block, wherein the second range of the MPR is determined based on a linear offset and the first range of the MPR, and wherein the linear offset is determined by
