| Abstract | We propose a resource allocation scheme based on the auction algorithm that aims at minimizing inter-cell interference (ICI) in multi-carrier LTE-A systems. The prices paid for resources by cell-edge users are infrequently exchanged between adjacent cells to help deciding who needs a specific resource the most. Furthermore, the Relative Narrowband Transmit Power (RNTP) indicator that is exchanged between cells in the LTE-A system is exploited to minimize the information exchange rate. When RNTP is used, only resources that suffer interference higher than a certain threshold are considered in the price exchange mechanism. Performance evaluation results show that the proposed scheme significantly improves the cell-edge throughput. The use of RNTP not only minimizes the exchange overhead, especially in a multi-carrier scenario, but it also improves the system performance as the cell neighbors would not avoid using a resource unless they are the culprit interferers to the original cell that uses it. |

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.
