Uplink Coordinated Scheduling Based on Resource Sorting

Uplink Inter-Cell Interference (ICI) and interference fluctuation degrades the uplink throughput of LTE/LTE-Advanced systems seriously. To deal with these problems, a coordinated scheduling method with resource sorting is proposed. In the proposed method, the uplink interference fluctuation is resisted by exploiting resource sorting and limiting the ICI generated by a given user to a predefined range. Meanwhile, the resources are allocated by differentiating the users' ability to bear the interference. Simulation results show that the proposed method outperforms traditional ICIC schemes, such as Fractional Frequency Reuse, fractional Transmit Power Control (TPC), and overload indicator based TPC.
