This paper proposes a capacity improving and energy saving scheduling scheme in push-based Converged Wireless Broadcasting and Cellular Network (CWBCN). We maximize the network capacity and alleviate request congestion through broadcasting/multi-casting the most popular services, and locally caching for further request on the user side. In the proposed scheme, we firstly introduce a UE (User Equipment)-based...
In this paper, we minimize the total energy used in a two-tier heterogeneous cellular network (HCN), through the optimization of resource partitioning and user association, assuming that both macro and small-cell base stations may be put into sleep mode. With resource partitioning, one tier of base stations can be put into sleep mode on a fraction of available time/frequency resources to reduce network...
We propose a new approach for jointly scheduling deep sleep and allocating pilot and data transmit power in small cells with the aim of minimising energy consumption while maximising user utility within a mixed macro/small cell network. Our approach exploits the relatively predictable nature of traffic load across each day/week and is demonstrated to achieve an average energy reduction of 37%, and...
