The method includes: determining, by first user equipment, a status of receiving at least one packet data convergence protocol layer protocol data unit PDCP PDU by second user equipment, where the at least one PDCP PDU is forwarded by the first user equipment to the second user equipment after being received by the first user equipment through a communications link between the first user equipment and a network device; and sending, by the first user equipment, a first status report to the network device, where the first status report is used to indicate the status of receiving the at least one PDCP PDU by the second user equipment.
