Enhanced intercell interference coordination (eICIC) is a key ingredient in boosting the performance of cochannel heterogeneous networks. eICIC encompasses two main techniques: almost blank subframes (ABS), during which the macrocell remains silent to reduce the interference; and biased user association to offload more users to the picocells. However, its application to realistic irregular deployments...
Dual connectivity (DC) is a promising technique to boost the user throughput performance by allowing user equipments (UEs) to receive data simultaneously from a macro cell and a small cell. In order to ensure high degree of realism and practical relevance of the results, we investigate the performance of DC in a realistic deployment based on three-dimensional data from a dense urban European capital...
Interference management for co-channel deployment of macro-cells and closed subscriber group (CSG) home-cells (HeNBs) are studied. We especially address the downlink macro-layer coverage-hole problem, where HeNBs may create too high interference to nearby macro-users, unless active interference management is applied. Interference management techniques based on HeNB power setting and partial Time Domain...
