Exploiting Dual Connectivity in Heterogeneous Cellular Networks
Narayan Prasad, Sampath Rangarajan
We consider network utility maximization problems over heterogeneous cellular networks (HetNets) that permit dual connectivity. Dual connectivity (DC) is a feature that targets eme…
Optimizing User Association and Activation Fractions in Heterogeneous Wireless Networks
Vaibhav Singh, Narayan Prasad, Mustafa Y. Arslan +1
We consider the problem of maximizing the alpha-fairness utility over the downlink of a heterogeneous wireless network (HetNet) by jointly optimizing the association of users to tr…
Exploiting Hybrid Channel Information for Downlink Multi-User MIMO Scheduling
Wenzhuo Ouyang, Narayan Prasad, Sampath Rangarajan
We investigate the downlink multi-user MIMO (MU-MIMO) scheduling problem in the presence of imperfect Channel State Information at the transmitter (CSIT) that comprises of coarse a…
A Simple Sequential Spectrum Sensing Scheme for Cognitive Radio
Yan Xin, Honghai Zhang
Cognitive radio that supports a secondary and opportunistic access to licensed spectrum shows great potential to dramatically improve spectrum utilization. Spectrum sensing perform…
