This report provides the baseline assumption related to environment, deployment, system design, and algorithms for the three test scenarios "base coverage urban", "microcellular", and "indoor" in which the WINNER system is exemplified and evaluated. Associated key assessment criteria are defined. Keyword list: baseline design, test scenarios, simulation(More)
With the inverse synthetic aperture radar (ISAR) imaging model, targets should move smoothly during the coherent processing interval (CPI). Since the CPI is quite long, fluctuations of a target’s velocity and gesture will deteriorate image quality. This paper presents a multiple-input–multiple-output (MIMO)-ISAR imaging method by combining MIMO techniques(More)
In this paper, a time-variant MIMO channel model is developed based on the EVIT-Advanced model. To adjust to the time variant propagation environment, the delays, angles of arrival (AoAs), angles of departure (AoDs) and initial phases, which are taken as constants during a short period of time in the IMT-Advanced model, are extended to the time variant(More)
A user association algorithm is proposed for energy consumption and traffic load balancing tradeoffs among heterogeneous base stations in heterogeneous networks with renewable energy supply. The concept of topology potential is introduced to represent the attraction between base stations and users, which takes the traffic load of users and the available(More)
This paper presents the concept of spectrum sharing in connection to beyond 3rd generation (B3G) systems. Inter-system spectrum sharing mechanisms are summarised and classified depending on their coordination capabilities and the relative priorities between the systems involved in the sharing. Novel radio resource management (RRM) functionalities for(More)
In cellular networks, multiple relay nodes can be deployed in one cell, so there are three transmission modes, direct transmission (DT), two-hop transmission (TT) and cooperative transmission (CT). Combining with the node sleeping method for power saving, different transmission modes will have different energy efficiency for different user equipment (UE).(More)
