Abstract

Systems, methods, and software described herein provide enhancements for allocating Long Term Evolution (LTE) resources to a wireless relay node. In one implementation, a method of operating a LTE access node includes receiving device summary reports from a wireless relay node that indicate at least the quantity of wireless communication devices connected to the wireless relay node. Based on the received summaries, the LTE access node may determine scheduling weights for the wireless relay node, wherein the scheduling weights indicate a probability of scheduling resources in comparison to other wireless communication devices communicating using the same quality of service class identifier as the wireless relay node.
