| Abstract(in English) | The 5G advanced wireless access system assumes a situation where more than 1,000 terminals with different communication quality requirements are mixed, mainly in the nano area formed by millimeter waves. We propose an implementation method to realize two wireless access methods proposed by UEC group. One of the wireless access methods is a grant-free non-orthogonal multiple access (GF-NOMA) method called 'PHLEX1,' which requires low computational complexity for active user detection (AUD), propagation channel estimation, and multi-user detection (MUD). The other is called 'PHLEX2', which is a system that realizes a communication channel with large capacity, high quality, and high stability by performing beamforming by cooperation among multiple base stations based on channel estimation. In order to realize multiple wireless communication systems that respond to different quality requirements and to switch between them according to the situation, we need a high degree of flexibility. This is the reason why we selected SDR approach. In addition to wideband wireless signal processing of millimeter waves, our research will be conducted on a DU implementation method that can be adapted to a RAN virtualization environment that controls multiple RUs with multiple antenna elements. |
