PAGE TITLE
Overview
PAGE SUMMARY
This technology is a technique to address the challenges of millimeter wave (mmWave) communication in the context of high-speed mobile networks, with a focus to reduce the overhead of analog beamforming. The novel approach utilizes reconfigurable antennas operating in the sub-6GHz frequency band to aid codebook-based beam selection in the mmWave band. By exploiting the spatial correlation between signal propagation at both frequency bands, an antenna system designed with this technique would significantly reduce the complexity of beam selection, making it more practical for real-world deployment. This approach has shown promising simulation results.
ADVANTAGES
TITLE:Key Advantages
Low Complexity Beamforming: Our approach employs a single RF chain in the sub-6GHz subsystem, making it less complex compared to methods requiring multiple RF chains at sub-6GHz frequencies
Reduced Beam Search Overhead: By leveraging spatial correlations between mmWave and sub-6GHz signals, the system achieves a substantial reduction in mmWave beam search overhead, up to 70% on average and 80% with a modest average gain loss of 3dB
Expanded network benefits and reduced infrastructure costs: Our approach would provide better coverage and fewer dropouts while being applicable in both indoor and outdoor environments
