Enhanced Inter-Cell Interference Coordination Challenges in Heterogeneous Networks
David Lopez-Perez, Ismail Guvenc, Guillaume de la Roche +3
3GPP LTE-Advanced has started a new study item to investigate Heterogeneous Network (HetNet) deployments as a cost effective way to deal with the unrelenting traffic demand. HetNet…
Downlink SDMA with Limited Feedback in Interference-Limited Wireless Networks
Marios Kountouris, Jeffrey G. Andrews
The tremendous capacity gains promised by space division multiple access (SDMA) depend critically on the accuracy of the transmit channel state information. In the broadcast channe…
Limited Feedback Over Temporally Correlated Channels for the Downlink of a Femtocell Network
Salam Akoum, Marios Kountouris, Robert W. Heath
Heterogeneous networks are a flexible deployment model that rely on low power nodes to improve the user broadband experience in a cost effective manner. Femtocells are an integral…
