Mixed-Timescale Online PHY Caching for Dual-Mode MIMO Cooperative Networks
An Liu, Vincent Lau, Wenchao Ding +1
Recently, physical layer (PHY) caching has been proposed to exploit the dynamic side information induced by caches at base stations (BSs) to support Coordinated Multi-Point (CoMP)…

Stochastic Successive Convex Optimization for Two-timescale Hybrid Precoding in Massive MIMO
An Liu, Vincent Lau, Min-Jian Zhao
Hybrid precoding, which consists of an RF precoder and a baseband precoder, is a popular precoding architecture for massive MIMO due to its low hardware cost and power consumption.…

Stochastic Successive Convex Approximation for Non-Convex Constrained Stochastic Optimization
An Liu, Vincent Lau, Borna Kananian
This paper proposes a constrained stochastic successive convex approximation (CSSCA) algorithm to find a stationary point for a general non-convex stochastic optimization problem,…
