Future cellular mobile radio networks will exhibit a much more dense base station deployment than 2nd or 3rd generation communications systems, particularly with regard to traffic coverage. Hence, a significant increase in power consumption of cellular networks can be expected. In order to counter this trend, energy efficiency of such networks should be increased considerably. Concerning energy efficiency,...
Efforts to increase the energy efficiency of information and communication systems in general and cellular mobile radio networks in particular has recently gained momentum. Besides positive environmental effects, lowering the energy consumption of mobile radio systems appears beneficial from an economical perspective. In this regard, the deployment of small, low power base stations, alongside conventional...
OFDMA-based IEEE802.16 implements among other features adaptive modulation and coding (AMC) which results in a different bit rate for each user depending on its position in the cell as well as the radio condition it experiences; users away from the base station experience lower throughput. In case of (intra-cell) mobility, the download time for the data user will thus depend on the different locations...
