Channel models are important tools to evaluate the performance of new concepts in mobile
communications. However, there is a tradeoff between complexity and accuracy. In this …

This paper presents an overview of the theory and currently known techniques for multi-cell
MIMO (multiple input multiple output) cooperation in wireless networks. In dense networks …

Coordinated multipoint or cooperative MIMO is one of the promising concepts to improve cell
edge user data rate and spectral efficiency beyond what is possible with MIMOOFDM in the …

In this paper, we analyze the ergodic sum-rate of a multi-cell downlink system with base
station (BS) cooperation using regularized zero-forcing (RZF) precoding. Our model …

(57) ABSTRACT A method for coordinated multipoint transmission includes collecting, in a
serving COMP-MA, channel state informa tion, CSIs, reported by terminals served by eNBs …

The tremendous growth of mobile data traffic will lead to substantial architectural changes in
wireless networks. New wireless systems need to exploit all available degrees of freedom in …

In this paper, we provide an overview on backhaul requirements in mobile networks
featuring inter-site cooperation. We consider a heterogeneous deployment, where small …

Direct device-to-device (D2D) communication is considered to be part of fifth generation
(5G) networks, while embodying vehicle-to-anything (V2X) communication into the recently …

In this paper we present experimental implementations of interference alignment (IA) and
coordinated multi-point transmission (CoMP). We provide results for a system with three …

Base station (BS) cooperation can turn unwanted interference to useful signal energy for
enhancing system performance. In the cooperative downlink, zero-forcing beamforming …
