Abstract: In this paper, the Signal to Interference plus Noise Ratio (SINR) estimation uncertainty is taken into consideration, and a novel optimal user association and resource allocation strategy is developed when there exists Almost Blank Subframe (ABS) in Heterogeneous Network (HetNet). To meet the demand of UEs with minimal resource, a model is formulated as a min-max regret generalized assignment problem. Simulation results validate the feasibility of the strategy.

Key words: communication technology, LTE-A HetNet, SINR estimation uncertainty problem, user selection association, resource allocation, min-max regret generalized assignment
