1. A method, comprising:
obtaining, by a first terminal device, a first parameter and location indication information that are configured by a radio access network device, wherein the first parameter is configured to be used to determine a data transmission resource of the first terminal device, and the location indication information indicates a location of first retransmission scheduling information corresponding to the first terminal device in retransmission scheduling information;
sending, by the first terminal device, uplink data to the radio access network device, and receiving the retransmission scheduling information sent by the radio access network device;
determining, by the first terminal device, a retransmission resource based on the retransmission scheduling information, the location indication information, and the first parameter; and
retransmitting, by the first terminal device, the uplink data to the radio access network device by using the retransmission resource.
