The terminal device determines an available resource in a shared carrier based on the resource occupation status, and communicates with the first access network device using the available resource. The first radio access network device can perform communication on the shared resource regardless of a status of the second radio access network device on the shared resource, so that the two radio access network devices flexibly and efficiently coexist in the shared carrier. This improves utilization of the shared resource.
