非均匀HetNet下基于增强几乎空白子帧的高效eICIC
An enhanced almost blank sub-frame management for efficient eICIC in non-uniform HetNets
摘要
Abstract
A new enhanced inter-cell interference coordination (eICIC) is adopted for managing almost blank sub-frame (ABS),which jointly exploits the time,frequency and power dimensions to improve the resource utilization.In particular,a non-uniform two tier heterogeneous network (HetNet) is considered,where the pico cells are located close to the macro cell and the number of users in each pico cell is different.To alleviate the interference caused by the co-channel deployment,the macro cells employ low power ABS (LP-ABS),and the resource blocks (RBs) are divided into two parts during an ABS.One is exclusively reserved for macro cell users and the other is reserved for pico cell users.The macro cells are allowed to use different percentages of RBs and different powers for their own transmission during the LP-ABS.The user association,resource allocation,ABS proportion,the frequency band partition parameter and the transmission power of macro cells are considered,aiming at maximizing the proportional fairness utility of the system.An iterative algorithm is also proposed and simulation results demonstrate that the proposed algorithm can improve both the system throughput and user fairness compared with the existing schemes.关键词
