Embodiments provide an information processing method and a terminal device, so that a network device can indicate a reserved resource, and the terminal device can process the reserved resource. In these embodiments, configuration information of a reserved resource sent by a network device can be received by a terminal device. The terminal device can determine, based on the configuration information of the reserved resource, that a resource type of the reserved resource is a first-type reserved resource or a second-type reserved resource. The terminal device can determine a radio frequency processing manner on the reserved resource based on the resource type.
