Example resource configuration methods and devices are described. One example resource configuration method includes applying to a network device for semi-persistent scheduling by a terminal device. The terminal device receives configuration information sent by the network device, where the configuration information is used to configure a first semi-persistent scheduling resource for the terminal device. The terminal device configures the first semi-persistent resource for the terminal device based on the configuration information, and sends uplink data to the network device on the first semi-persistent scheduling resource.
