Centralized & Distributed Deep Reinforcement Learning Methods for Downlink Sum-Rate Optimization
Ahmad Ali Khan, Raviraj Adve
For a multi-cell, multi-user, cellular network downlink sum-rate maximization through power allocation is a nonconvex and NP-hard optimization problem. In this paper, we present an…

Optimizing the MIMO Cellular Downlink: Multiplexing, Diversity, or Interference Nulling?
Kianoush Hosseini, Caiyi Zhu, Ahmad Khan +2
A base-station (BS) equipped with multiple antennas can use its spatial dimensions in three different ways: (1) to serve multiple users, thereby achieving a multiplexing gain, (2)…
