1. A method, comprising:
performing, by a terminal device, data transmission according to a first configuration parameter of a currently activated first bandwidth part (BWP), wherein the first configuration parameter of the currently activated first BWP comprises a first resource offset and a first bandwidth;
determining, by the terminal device, a first random access resource and a second configuration parameter for random access if the currently activated first BWP does not include a random access resource when a random access procedure is initiated, wherein the second configuration parameter comprises a second resource offset and a second bandwidth, wherein a configuration parameter of a second BWP comprises the first random access resource and the second configuration parameter;
sending, by the terminal device, a random access request to a network device on the first random access resource; and
receiving, by the terminal device, a random access response according to the second configuration parameter, wherein receiving the random access response according to the second configuration parameter comprises:
determining first scheduling information according to the second configuration parameter, wherein the first scheduling information indicates a first resource; and
receiving, by the terminal device on the first resource, the random access response from the network device;
parsing, by the terminal device based on the second configuration parameter, second scheduling information carried in the random access response;
sending a random access message to the network device based on the second scheduling information; and
forcibly stopping, by the terminal device, in response to the terminal device receiving indication information for deactivating the currently activated first BWP, a random access procedure.
