This application provides a short-distance communication method, an apparatus, and a system, applied to the field of short-distance communication, for example, a cockpit domain. The method includes: obtaining at least one piece of code data; sending a scheduling type indication and a data type indication to a second device, where the scheduling type indication is used to indicate that the at least one piece of code data includes initially transmitted data, retransmitted data, or initially transmitted data and retransmitted data, and the data type indication is used to indicate location information and/or an amount of a part or all of the at least one piece of code data; and sending the at least one piece of code data to the second device. In this solution, when sending the code data to the second device, a first device can choose to send only the initially transmitted data, the retransmitted data, or the initially transmitted data and the retransmitted data based on the to-be-sent code data and a currently available physical resource. This can maximize utilization of the available physical resource, improve resource utilization, and reduce resource waste.
