| Abstract | This paper proposes a s.c. 2 ms range extension scheme for High Speed Uplink Packet Access (HSUPA) networks to avoid potential coverage problems and usage of multiple TTI lengths. With range extension UEs in poor radio conditions are configured to send bundles of 2 ms TTI transmissions without HARQ feedback to improve their coverage. This paper analyzes the performance of range extension in comparison with normal 2 ms TTI performance with multiple inter-site distances. The analysis is conducted considering VoIP performance due to its high sensitivity to additional delays and packet loss. The results acquired by using system level simulation tool indicate that using 2 ms range extension can improve system capacity in larger cells where normal 2 ms TTI can result into coverage problems. Moreover, utilizing repeated 2 ms TTIs instead 10 ms TTIs enables increased battery saving opportunities when UL DTX is applied. |

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.
