Abstract
Embodiments of the present invention provide a method, a device, and a system for transmitting data based on a hybrid automatic repeat request (HARQ). The method includes: adjusting, according to current physical resources, a channel quality indicator (CQI) fed back by a terminal to obtain an adjusted CQI and determining an initial transmit power corresponding to the adjusted CQI; calculating an optimum number NRV of redundant versions (RVs) according to a signal-to-noise ratio (SNR) gain, the adjusted CQI, and a requirement on quality of service of the terminal; adjusting the initial transmit power according to the optimum number of RVs and the adjusted CQI; and using NRV transmit time intervals (TTIs) and the adjusted transmit power to transmit NRV RVs of a transport block (TB) to the terminal. The embodiments of the present invention further provide a base station, a terminal, and a system for transmitting data.
