Abstract
One example method includes receiving, by a first IAB node, N data packets from a donor base station to a terminal device. The first IAB node can determine a PDCP PDU SN of a first data packet in PDCP PDU SNs of the N data packets, where the PDCP PDU SN of the first data packet is a largest PDCP PDU SN in the PDCP PDU SNs of the N data packets, or the PDCP PDU SN of the first data packet is a largest PDCP PDU SN in consecutive PDCP PDU SNs starting from a smallest PDCP PDU SN in the PDCP PDU SNs that are of the N data packets and that are arranged in ascending order. The first IAB node can send first information to the donor base station, where the first information includes a value of the PDCP PDU SN of the first data packet.
