一般注記In this deliverable, we address several aspects related to physical transmission and medium accessfor the links-on-the-fly concept. After a brief review of lossy forwarding and RESCUE requirements on the physical and medium access control layers, we present three parts: First, we study multiple-input multiple-output (MIMO) beamforming to improve system reliability and spectrum efficiency in the context of lossy forwarding, specifically a MIMO multi-relay system with random beamforming and limited feedback.The approach exploits link correlation information in order to mitigate error propagation effects. Twouser scheduling strategies are proposed and assessed by means of theoretical and numerical analysis. Second, we consider the relay network of toy scenario 1 as a virtual multiple-input single-output (MISO) system. Then, we evaluate the performance by employing lossy forwarding and investigate the tradeoff between high communication reliability (diversity gain) on the one side and high throughput for a fixed reliabilitylevel (multiplexing gain) on the other side. We compare the lossy forwarding scheme with the conventional decode-and-forward scheme in terms of diversity and multiplexing gain by means of theoretical and numerical analysis. Third, we extend the RESCUE system to a general multi-user multi-way relay network. Based on this model, we explore the use of coded random access as a promising wireless access technique and develop a framework that allows to investigate the combination of lossy forwarding and the coded random access schemes.
