Abstract: When a quantity of radio resources available for a terminal device is less than a quantity of required radio resources, the terminal device sends a request to another terminal device, to request the another terminal device to release at least one radio resource currently used by the another terminal device or reselect a radio resource. The another terminal device that receives the request may autonomously release or request a network to release the at least one radio resource currently used by the another terminal device, or autonomously reselect or request a network to reselect the radio resource, and send a response to the terminal that sends the request. Nonconsecutive fragmented radio resources may be integrated into consecutive and relatively large radio resources, so that radio resource fragments are reduced, and the terminal device can send control information and data in a timely manner, thereby improving radio resource utilization.
