Asymptotic Scaling Laws of Wireless Adhoc Network with Physical Layer Caching
An Liu, Vincent Lau
We propose a physical layer (PHY) caching scheme for wireless adhoc networks. The PHY caching exploits cache-assisted multihop gain and cache-induced dual-layer CoMP gain, which su…

Optimal Hierarchical Radio Resource Management for HetNets with Flexible Backhaul
Naeimeh Omidvar, An Liu, Vincent Lau +3
Providing backhaul connectivity for macro and pico base stations (BSs) constitutes a significant share of infrastructure costs in future heterogeneous networks (HetNets). To addres…

Two-Stage Subspace Constrained Precoding in Massive MIMO Cellular Systems
An Liu, Vincent Lau
We propose a subspace constrained precoding scheme that exploits the spatial channel correlation structure in massive MIMO cellular systems to fully unleash the tremendous gain pro…
