Joint Power and Antenna Selection Optimization in Large Cloud Radio Access Networks
An Liu, Vincent Lau
Large multiple-input multiple-output (MIMO) networks promise high energy efficiency, i.e., much less power is required to achieve the same capacity compared to the conventional MIM…
Mixed-Timescale Precoding and Cache Control in Cached MIMO Interference Network
An Liu, Vincent Lau
Consider media streaming in MIMO interference networks whereby multiple base stations (BS) simultaneously deliver media to their associated users using fixed data rates. The perfor…
Cache-Enabled Opportunistic Cooperative MIMO for Video Streaming in Wireless Systems
An Liu, Vincent Lau
We propose a cache-enabled opportunistic cooperative MIMO (CoMP) framework for wireless video streaming. By caching a portion of the video files at the relays (RS) using a novel MD…
Hierarchical Interference Mitigation for Massive MIMO Cellular Networks
An Liu, Vincent Lau
We propose a hierarchical interference mitigation scheme for massive MIMO cellular networks. The MIMO precoder at each base station (BS) is partitioned into an inner precoder and a…
Hierarchical Radio Resource Optimization for Heterogeneous Networks with Enhanced Inter-cell Interference Coordination (eICIC)
An Liu, Vincent K. N. Lau, Liangzhong Ruan +2
Interference is a major performance bottleneck in Heterogeneous Network (HetNet) due to its multi-tier topological structure. We propose almost blank resource block (ABRB) for inte…
Duality and Optimization for Generalized Multi-hop MIMO Amplify-and-Forward Relay Networks with Linear Constraints
An Liu, Vincent K. N. Lau, Youjian Liu
We consider a generalized multi-hop MIMO amplify-and-forward (AF) relay network with multiple sources/destinations and arbitrarily number of relays. We establish two dualities and…
