| Abstract | Complementing macro-only cellular networks with low-powered base stations is a promising deployment solution to cope with exploding data traffic in the coming years. In Long Term Evolution (LTE)-Advanced, interference mitigation technologies, like the linear interference rejection combining (IRC) receiver and Enhanced Inter-Cell Interference Coordination (eICIC), are introduced to address the co-channel interference between macro and small cells in downlink. These advanced techniques will boost the performance of small cells, and impact the network deployment upgrade. In this paper, LTE-A small cell deployments are evaluated through a network upgrade case study. A network upgrade with small cell deployments is simulated in a realistic metropolitan scenario to satisfy the traffic growth forecast over a period of ten years. A dynamic system level simulator is used to model the network behavior of IRC receiver and eICIC. The deployment time, scale and cost of the small cells improved by interference mitigation solutions are presented. The simulation results show that small cell deployments are the fundamental way to increase the system capacity as well as that eICIC is a promised solution to improve the system capacity. An increase of 56% in system capacity, which corresponds to a ~19 month network upgrade delay and 34% cost savings , can be achieved by eICIC in the case where small cells deployments become very dense. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
