The present invention relates to a radio resource scheduling method and apparatus. The method includes: when a sending end receives a negative acknowledgement NACK message fed back by a receiving end, acquiring, by the sending end, data whose response message is the negative acknowledgement message as data to be retransmitted, where the data to be retransmitted includes at least one transport block; and determining, by the sending end according to a radio link control RLC status report sent by the receiving end, whether the receiving end successfully receives each transport block of the data to be retransmitted, and if all the transport blocks of the data to be retransmitted are successfully received, canceling retransmission of the data to be retransmitted; or if not all the transport blocks of the data to be retransmitted are successfully received, retransmitting a transport block that is in the data to be retransmitted and is not successfully received. The present invention effectively solves a problem of repeated retransmission caused when an ACK is erroneously detected as a NACK, so that data that has been successively transmitted may be prevented from being retransmitted, thereby saving a bandwidth resource and improving utilization efficiency of a frequency spectrum. |
