Semantic Communications using Foundation Models: Design Approaches and Open Issues
Peiwen Jiang, Chao-Kai Wen, Xinping Yi +3
Foundation models (FMs), including large language models, have become increasingly popular due to their wide-ranging applicability and ability to understand human-like semantics. W…
Large System Achievable Rate Analysis of RIS-Assisted MIMO Wireless Communication with Statistical CSIT
Jun Zhang, Jie Liu, Shaodan Ma +2
Reconfigurable intelligent surface (RIS) is an emerging technology to enhance wireless communication in terms of energy cost and system performance by equipping a considerable quan…
A Deep Learning Framework for Optimization of MISO Downlink Beamforming
Wenchao Xia, Gan Zheng, Yongxu Zhu +3
Beamforming is an effective means to improve the quality of the received signals in multiuser multiple-input-single-output (MISO) systems. Traditionally, finding the optimal beamfo…
Power Minimization Based Joint Task Scheduling and Resource Allocation in Downlink C-RAN
Wenchao Xia, Jun Zhang, Tony Q. S. Quek +2
In this paper, we consider the network power minimization problem in a downlink cloud radio access network (C-RAN), taking into account the power consumed at the baseband unit (BBU…
Joint Optimization of Fronthaul Compression and Bandwidth Allocation in Uplink H-CRAN with Large System Analysis
Wenchao Xia, Jun Zhang, Tony Q. S. Quek +2
In this paper, we consider an uplink heterogeneous cloud radio access network (H-CRAN), where a macro base station (BS) coexists with many remote radio heads (RRHs). For cost-savin…
DFT-Based Hybrid Beamforming Multiuser Systems: Rate Analysis and Beam Selection
Yu Han, Shi Jin, Jun Zhang +2
This paper considers the discrete Fourier transform (DFT) based hybrid beamforming multiuser system and studies the use of analog beam selection schemes. We first analyze the uplin…
