Beam Training and Tracking for Extremely Large-Scale MIMO Communications
Kangjian Chen, Chenhao Qi, Cheng-Xiang Wang +1
In this paper, beam training and beam tracking are investigated for extremely large-scale multiple-input-multiple-output communication systems with partially-connected hybrid combi…
Simultaneous Beam Training and Target Sensing in ISAC Systems with RIS
Kangjian Chen, Chenhao Qi, Octavia A. Dobre +1
This paper investigates an integrated sensing and communication (ISAC) system with reconfigurable intelligent surface (RIS). Our simultaneous beam training and target sensing (SBTT…
Two-Step Codeword Design for Millimeter Wave Massive MIMO Systems with Quantized Phase Shifters
Kangjian Chen, Chenhao Qi, Geoffrey Ye Li
In this paper, a two-step codeword design approach for millimeter wave (mmWave) massive MIMO systems is presented. Ideal codewords are first designed, which ignores the hardware co…
Beam Training based on Dynamic Hierarchical Codebook for Millimeter Wave Massive MIMO
Kangjian Chen, Chenhao Qi
Beam training based on hierarchical codebook for millimeter wave (mmWave) massive MIMO is investigated. Unlike the existing work using the same hierarchical codebook to estimate di…
