Protocol data unit set-based communication method and related apparatus

Abstract

This application discloses a protocol data unit set–based communication method and a related apparatus. The method includes: An access network device receives first information, where the first information is used to enable the access network device to determine a retransmission mechanism of one or more PDU sets; and the access network device disables retransmission of a part or all of data packets of a first PDU set based on the first information, where the first PDU set belongs to the one or more PDU sets. The access network device determines a retransmission mechanism of a data packet of a PDU set based on an external indication. Retransmission of the part or all of the data packets of the first PDU set is disabled, so that a delay can be reduced, network resource occupation can be reduced, and a data throughput can be improved.
