基于先进小区干扰协调技术的异构网络联合资源分配
Joint Resources Allocation for Enhanced Inter-cell Interference Coordination in Heterogeneous Networks
摘要
Abstract
Resources allocation between high-power macro base stations( BSs) and low-power microBSs deeply impact the performance of heterogeneous networks( HetNets) . It is a joint optimization problem:( i) the UE association with eNBs,( ii) the amount of radio resource that macros should reserve for picos,and ( iii) the resource scheduling strategy in each eNBs. The block coordinate decent( BCD) method is applied and a class of novel algorithms is developed to solve the joint problem. The solution can be deployed in dis-tributed manner and implemented using enhance intercell interference coordination ( eICIC ) proposed by exiting LTE-A protocols. Extensive evaluation of proposed algorithms is performed on a dynamic system-level simulation and the numerical results show a significant gain for the users. System utilities and fairness are greatly enhanced with proposed algorithms.关键词
