Large Scale Antenna System Use many more service-antennas than terminals ssing Unit Proce with data beams directed towards the terminals Increased spectral efficiency (bits/ s/ Hz) and radiated energy efficiency (bits/ Joule) Technological advantages: Only needs cheap, single-antenna terminals All complexity at the base station Expensive power amplifier amplifiers replaced by many low-power low-precision units Important to consider total system energy consumption and energy efficiency: Radiated power LS AS-critical computing processing power Internal per-antenna power consumption (RF chains, analog blocks, A/ D) 7 GreenTouch Proprietary
Beyond Cellular Green Generation sleep sleep sleep Data Signaling sleep Beyond “cellular” coverage sleep Separate with data capacity on demand Opportunities for sustainability: Challenges: System designed for energy efficiency New system architecture Re-invent mobility management • Separate capacity from coverage Agile management, context aware, • Optimise signalling transmission network with memory • Lean access to system Hardware for fast reconfiguration Cope with massive amount of low data rate services 8 GreenTouch Proprietary
