Enhanced intercell interference coordination challenges in heterogeneous networks
Enhanced intercell interference coordination challenges in heterogeneous networks
3GPP LTE-Advanced has recently been investigating heterogeneous network (HetNet) deployments as a cost effective way to deal with the unrelenting traffic demand. HetNets consist of a mix of macrocells, remote radio heads, and low-power nodes such as picocells, femtocells, and relays. Leveraging network topology, increasing the proximity between the access …
