Abstract

Provided is a radio resource management method for device-to-device communication. The resource management method for device-to-device communication includes dividing a plurality of connection identifiers (CIDs) into N (N is a natural number) number of groups, dividing the resources for device-to-device communication into N number of sub-bands corresponding to the N number of groups, and allocating resources by mapping CIDs respectively belonging to the N number of groups to resources of sub-bands respectively corresponding to the groups. Therefore, according to the resource management method, by dividing the whole frequency band into a plurality of sub-bands, a communication range may be extended, a low-power device may be accommodated, granularity of resources may be improved, and flexibility of resource management may be obtained.

First claim

What is claimed is:

1. A method for managing resources for a traffic step of device-to-device communication, the method comprising:
dividing, by a mobile device, a plurality of connection identifiers (CIDs) into N (N is a natural number) number of groups;
dividing, by the mobile device, the resources for device-to-device communication into N number of sub-bands corresponding to the N number of groups; and
allocating, by the mobile device, the resources by mapping CIDs respecti…
