Abstract | Time domain enhanced intercell interference coordination with Almost Blank Subframe (ABS) configuration for Macrocell is proposed in 3GPP to mitigate the inter-tier interference for heterogeneous networks (HetNets) consisting of Macrocells and overlaying Picos. The existing schemes for ABS power optimization are mainly base on the same level muted power of ABS, which will either cause time-frequency resource waste for Macrocell with zero power ABS or reduce the Pico cell range expansion capability with low power ABS. In this paper, we propose a multilevel power ABS scheme with resource management to conquer these problems. The simulation results show that our proposed scheme can improve the network throughput and protect the cell range expansion (CRE) area user effectively. |

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.
