Millimeter Wave A new radio interface for 5G
Advanced antenna and multi-site technologies
Novel duplexing schemes
• 3D-beamforming and MU-MIMO
• Active Antenna System (AAS)
• Massive MIMO • Network MIMO
Advanced waveforms and multiple access
• More flexible waveforms than pure OFDM (e.g. RBF-OFDM; FBMC; etc.)
• Non-orthogonal multiple access (NOMA)
• Broader set of modulation and coding schemes
