Abstract
A data transmission method and an apparatus are provided. A transmit device sends a plurality of pieces of data, wherein different data in the data occupies different transmission resources. A first receive device in a multicast group receives the data; determines a first feedback message based on a decoding result of the data; feeds back the first feedback message to the transmit device which distinguishes, based on the first feedback message, which data in the plurality of pieces of data is correctly decoded by the multicast group and which data is not, wherein the first feedback message indicates whether the first receive device correctly decodes the data; and performs network encoding transmission on the incorrectly decoded data, thereby improving retransmission efficiency, reducing a delay, and saving feedback resources.
