The embodiments of the present application provide a resource scheduling method for same frequency networking in an LTE cluster system and a device thereof. The method includes: determining a first frequency domain resource in the LTE cluster system, wherein the first frequency domain resource is an accessible frequency domain resource available for group services and belongs to a frequency domain resource of the cluster system; dividing the first frequency domain resource into at least two frequency domain resource groups; and selecting one frequency domain resource group from the at least two frequency domain resource groups to perform group services when a newly-built group service exists, so as to implement same frequency networking resource scheduling. The embodiments of the present application can reduce or eliminate the same frequency interference in the group services.
