Enhanced Group Sparse Beamforming for Green Cloud-RAN: A Random Matrix Approach
Group sparse beamforming is a general framework to minimize the network power consumption for cloud radio access networks (Cloud-RANs), which, however, suffers high computational complexity. In particular, a complex optimization problem needs to be solved to obtain the remote radio head (RRH) ordering criterion in each transmission block, which will help to determine the active RRHs and the ass...
متن کاملOptimal Stochastic Coordinated Beamforming with Compressive CSI Acquisition for Cloud-RAN
Cloud radio access network (Cloud-RAN) is a revolutionary RAN architecture. It provides a cost-effective way to improve both the network capacity and energy efficiency by shifting the baseband signal processing to a single baseband unit (BBU) pool, which enables centralized signal processing. However, in order to exploit the performance gains of full cooperation, full channel state information ...
متن کاملGroup Sparse Precoding for Cloud-RAN with Multiple User Antennas
Cloud radio access network (C-RAN) has become a promising network architecture to support the massive data traffic in the next generation cellular networks. In a C-RAN, a massive number of low-cost remote antenna ports (RAPs) are connected to a single baseband unit (BBU) pool via high-speed low-latency fronthaul links, which enables efficient resource allocation and interference management. As ...
متن کاملRobust Transmission for Massive MIMO Downlink with Imperfect CSI
In this paper, the design of robust linear precoders for the massive multi-input multi-output (MIMO) downlink with imperfect channel state information (CSI) is investigated, where each user equipment (UE) is equipped with multiple antennas. The imperfect CSI for each UE obtained at the BS is modeled as statistical CSI under a jointly correlated channel model with both channel mean and channel v...
متن کاملRobust Optimization for MIMO Transmissions with Imperfect CSI
We investigate the problem of robust joint transmitter and receiver power allocation for uplink multiuser multi-input multi-output (MIMO) transmissions. The channel model is assumed to have Rayleigh flat fading. The objective of power allocation is to minimize the maximum MSE among all users each of which has limited transmit power. We investigate robust joint transmitter and receiver power all...
