Long Term Evolution (LTE) Carrier Aggregation (CA) was introduced by the Release-10 3GPP specifications. CA allows aggregation of up to 5 cells for a terminal;both downlink (DL) CA and uplink (UL) CA are supported by the 3GPP specifications. However, the first commercial deployments focus on the aggregation of two cells in the downlink. The benefits of LTE CA are increased terminal peak data rates, aggregation of fragmented spectrum and fast load balancing. In this paper, we analyze different strategies of DL scheduling for LTE CA including centralized, independent and distributed schedulers, we provide the corresponding simulation results considering UE data rate limitations and different traffic models. Also, we compare the performance of a single LTE carrier with LTE CA using the same total bandwidth.
The increasing interest drawn to LTE system requires the analysis of train-ground communication channel. By the approval of the Ministry of Railways of China, extensive and practical measurements are performed on Harb...

Lead users can be a valuable source for innovation. They are capable of detecting and experiencing needs before the general market does, and are willing to innovate because they can gain significant benefits if their needs are fulfilled. Several authors have highlighted the use of disabled persons, framed as lead users, to foster innovation in new product development. In this article, we review 18 cases where disabled users are framed as lead users, identifying common characteristics within these cases. The characteristics include the product categories where disabled lead user innovation occurs and how lead users were involved in these cases. Additionally, we look at the selection process of disabled lead users and how this relates to the classic approach of lead user innovation. Finally, we propose further opportunities for lead user innovation using disabled persons, and the challenges facing research in this domain.
