METHOD AND APPARATUS FOR RETRANSMITTING DATA

摘要

Provided are a method and apparatus for retransmitting data, which are used for solving the problem in the prior art of network transmission resource waste. The method includes: after it is determined that decoding a received data block has failed, sending an instruction message to a terminal, the instruction message being used for instructing the terminal to retransmit the data block; receiving all data blocks retransmitted by the terminal during the retransmission process at this time according to the instruction message, wherein the number of times of retransmitting the data blocks during the retransmission process is less than that of normally transmitting the data blocks by the terminal; and jointly decoding the received data blocks retransmitted by the terminal during the retransmission process at this time and all data blocks that are already cached, the cached data blocks comprising received data blocks normally transmitted by the terminal or comprising the received data blocks normally transmitted by the terminal and the received data blocks that have already been retransmitted by the terminal.
