Abstract

Heterogeneous networks (HetNets) are intended to offer wide area coverage and high data rate transmission by deploying small cells besides macrocells. One way to improve the system throughput is intercell interference coordination. The coordination methods in literature use the system throughput as the only selection criteria without considering each user's data rate requirement and investigate the intercell interference only during the period when small cell's edge users are served. In this paper, we propose an algorithm to maximize the users' data rate satisfaction ratio in HetNet leveraging on the two existing intercell interference coordination schemes ABS and CoMP. Intensive simulations are conducted and the results demonstrate that our proposed scheme achieves considerable gains over competing schemes in terms of the data rate satisfaction ratio and the system capacity in Config.4b scenarios defined by 3GPP.
