Method for resource scheduling and related devices

A terminal, comprising:

• at least one processor;
• and
• a computer readable storage, coupled with the at least one processor and storing at least one computer executable instruction therein which, when executed by the at least one processor, causes the at least one processor to:
• determine a service type of a data service, wherein the data service is determined to be periodic when the data service is a non-periodic service that approximates a periodic service;
• when the data service is determined to be periodic, send a periodic service request through higher layer signaling to another terminal, wherein the periodic service request is forwarded by the other terminal to a base station, the other terminal is within coverage of the base station, and the terminal is outside the coverage of the base station;
• and
• receive a scheduled resource from the other terminal, wherein the scheduled resource is sent from the base station to the other terminal through the higher layer signaling according to the periodic service request.
