In wireless cellular systems, cell edge users can only achieve far less capacity than cell center uses because of low receive signal power and strong inter-cell interference. Base station joint transmission has been proven to be an effective method to mitigate this effect. In this paper, we propose a novel precoding scheme for non-coherent joint transmission where both base stations and mobile stations...
The goal of this paper is to present the main achievements reached within the WINNER+ project concerning, in particular, clustering as a way to improve the feasibility of joint processing schemes as enablers of coordinated multipoint solutions. Three different approaches are presented. First, a single and static cluster of base stations is considered. In this case, a user-centric partial joint processing...
