摘要： 将信干噪比估计不确定问题引入到有几乎空白子帧存在时的异构网络中,在异构网络中提出一种新的用户选择接入和资源分配联合算法。为了用最少的无线资源满足用户的传输速率需求,将问题建模为最小-最大差值广义分配模型,然后进行求解。仿真结果验证了本文方法的可行性。

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
