Abstract

The ever-increasing focus on the environment has led to energy considerations throughout industry. The Mobile Phone industry is no exception. Researchers and Commercial organisations are examining system design and associated technologies which will minimize energy consumption whilst retaining current system performance. Techniques across the mobile industry are being considered from Energy Efficient air interface design to equipment "switch-off" (during periods of low usage). This paper considers the impact of, dual, co-located, system traffic loading in relation to Multiple Input Multiple Output (MIMO) scheduling techniques and Dynamic Carrier Band Switching for the 3GPP WCDMA Downlink in order to maximize throughput whilst ensuring Energy Efficiency.
