The terminal 100 may further include the power supply 111 (for example, a battery) supplying power to all components. Optionally, the power supply 111 may be logically connected to the processor 110 through a power management system. In this way, functions such as charge management, discharge management, and power consumption management are implemented by using the power management system.

In addition, the terminal 100 includes some functional modules that are not illustrated. Details are not described herein.

FIG. 7 is a schematic diagram of a hardware structure of a network device for implementing the embodiments of the present disclosure. The network device 600 includes a processor 601, a transceiver 602, a memory 603, a user interface 604, and a bus interface.

The transceiver 602 is configured to send first resource configuration information to a terminal, where the first resource configuration information is used to indicate M first frequency resources and N second frequency resources, and M and N are positive integers greater than or equal to 1. The transceiver 602 is further configured to receive a random access request sent by the terminal on a target first frequency resource, and send a random access response on a target second frequency resource to the terminal, where the target first frequency resource is a free frequency resource in the M first frequency resources, and the target second frequency resource is a free frequency resource in the N second frequency resources.
