Abstract: Embodiments of this disclosure provide a communication method and apparatus, to reduce a waiting delay during transmission of retransmitted data and out-of-order data. In this method, a user plane function network element may receive first data and second data, determines, based on first information, that the second data is retransmitted data of the first data, and sends indication information to an access network network element. The indication information herein may indicate that the second data is the retransmitted data, or indicate a sending priority of the second data. Based on this solution, the access network network element may send the first data and the second data based on the indication information, and may preferentially send the retransmitted data to reduce the waiting delay during data transmission.
