| Abstract | This paper comprehensively compares our two previously reported inter-cell interference coordination (ICIC) methods based on frequency block-dependent coordinated transmission power control (TPC) in non-orthogonal access with a successive interference canceller (SIC) in the cellular uplink. First ICIC method uses different target signal-to-noise ratios (SNRs) and compensation factors in fractional TPC (FTPC) among frequency blocks, which are coordinated among neighboring cells. Second ICIC method uses TPC based on inter-cell interference power in addition to the conventional received signal power-based FTPC, where the allowable inter-cell interference power among multiple frequency blocks within the system bandwidth are coordinated among neighboring cells. Based on computer simulation, we show that ICIC using either of our previously reported TPC methods enhances the system-level throughput compared to the conventional universal frequency reuse (UFR) without ICIC and fractional frequency reuse (FFR) since the proposed ICIC methods alleviate the degradation in multiuser diversity and the non-orthogonal user multiplexing effect compared to the conventional FFR, which achieves a similar ICIC effect. Between the two previous ICIC methods, the ICIC method using TPC based on inter-cell interference power achieves the best throughput performance. |

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.
