The increasing demand for mobile broadband is pushing existing 3G networks closer to their capacity limit. Additional carriers together with new HSPA features (HSPA+) are expected to provide the next necessary boost in network capacity. One specific feature in HSPA+ is referred to as Dual-Cell HSDPA (or Dual-Carrier HSDPA). This feature allows for a single user to be simultaneously scheduled over two carriers, effectively doubling its achievable data rate. The addition of a secondary carrier… Expand

An efficient power-saving downlink transmission scheme in OFDM-based multiple component carrier systems
TLDR
This study proposes a technique for dynamic power adjustment to enable energy-efficient data transmissions and demonstrates that the energy consumption of the proposed scheme is much better than that of the case in which all CCs are always active, when both schemes maintain the required QoS. Expand
Energy Efficient Evolution of Mobile Broadband Networks
TLDR
An analysis compares a number of network evolution strategies, determining which provides the necessary performance while limiting the increase in power consumption, and concludes that a hybrid solution involving the upgrade of existing macro base station sites together with the deployment of outdoor or indoor small cells provide the best compromise between performance and power consumption.
