Journal ArticleDOI
Performance Analysis of Simple Channel Feedback Schemes for a Practical OFDMA System
Klaus I. Pedersen,Troels Kolding,Istvan Z. Kovacs,Guillaume Monghal,Frank Frederiksen,Preben Mogensen +5 more
TL;DR: The so-called average best-M scheme is the most attractive channel feedback solution, where only the average channel quality for the best M subbands is reported, together with a bit mask identifying those subbands.
Proceedings ArticleDOI
Dual-Cell HSDPA for Network Energy Saving
TL;DR: An energy saving feature is proposed that exploits variations in network traffic and determines if the secondary carrier is detrimental for reaching some pre-set minimum requirements, resulting in an energy saving ranging between 14% and 36%.
Journal ArticleDOI
Empirical Low-Altitude Air-to-Ground Spatial Channel Characterization for Cellular Networks Connectivity
Xuesong Cai,Tomasz Izydorczyk,Jose Rodriguez-Pineiro,Istvan Z. Kovacs,Jeroen Wigard,Fernando M. L. Tavares,Preben Mogensen +6 more
TL;DR: In this article, a measurement campaign for the A2G channels is introduced, where a uniform circular array (UCA) with 16 antenna elements was employed to collect the downlink signals of two different Long Term Evolution (LTE) networks, at the heights of 0-40m in three different, namely rural, urban and industrial scenarios.
Journal ArticleDOI
Capacity gain of beamforming techniques in a WCDMA system under channelization code constraints
TL;DR: This study addresses the performance of a wideband code-division multiple-access mobile communications system with beamforming antenna arrays (AAs) at the base station, synthesizing a grid of beams, and the soft capacity mechanism associated with partial deployment of AAs in a subset of the cells in the network is addressed.
Self-Organizing Coalitions for Conflict Evaluation and Resolution
Gustavo Wagner Oliveira Da Costa,Luis Guilherme Uzeda Garcia,Andrea F. Cattoni,Klaus I. Pedersen,Preben Mogensen +4 more
TL;DR: The proposed algorithm consists of a set of distributed and scalable rules for building coalitions; these rules essentially resolve the conflicts among avid femtocells competing for a limited amount of resources.
