| Abstract | With various packet-switched networks coming to the fore, real-time services like voice and video, transmitted traditionally using circuit-switched bearers, can have limited capacity due to the limited availability of resource-granting control channels. Such packets are frequent and require more grants compared to other services like FTP. To compound the issue, often these packets are large in size compared to available resources for allocation. To improve the capacity of real-time communication over LTE (-A), various scheduling methods are being studied. However, often the packet sizes are unaccounted for by these studies. This work deals with the development of semi-persistent scheduling (SPS) algorithms based on wide-band time-average SINR information for resource allocation to voice traffic users, with a focus on large packets. A comparative study between dynamic scheduling (DS) and developed SPS algorithms is done to determine the suitable scheduling mechanism for voice packets transmission over LTE (-A) systems in the downlink. |

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.
