User Association and Hybrid Beamforming Designs for Cooperative mmWave MIMO Systems

no code implementations10 Aug 2022 Pengfei Ni, Rang Liu, Ming Li, Qian Liu

In an effort to further exploit multiple-antenna diversities, we also consider the dynamic subarray architecture and propose a novel antenna design algorithm for the analog beamforming design.

Partially Distributed Beamforming Design for RIS-Aided Cell-Free Networks

no code implementations10 Aug 2022 Pengfei Ni, Ming Li, Rang Liu, Qian Liu

Cell-free networks are regarded as a promising technology to meet higher rate requirements for beyond fifth-generation (5G) communications.

BS-RIS-User Association and Beamforming Designs for RIS-aided Cellular Networks

no code implementations27 Jun 2021 Sifan Liu, Pengfei Ni, Rang Liu, Yang Liu, Ming Li, Qian Liu

During the dynamical access process, an iterative algorithm is proposed to alternatively obtain the active and passive beamforming.
