The Role of Massive and Network MIMO for 5G

Call for Papers

By factors higher capacity or spectral efficiency compared to current 3GPP LTE networks will have to be supported in future 5G networks. With massive MIMO a new paradigm has come up promising the solution of many of these challenges by overprovisioning of antenna elements. For example intercell interference as one of the main limitations of cellular networks can be reduced to any wanted level by applying sufficiently large antenna arrays. Despite a high number of publications in this field there is still a significant gap between theoretical results and practical realizations. While channel sounder measurements verify the great potential in real world scenarios, issues like costs for an increasing number of RF chains, HW nonidealities, inaccurate channel knowledge, undesired antenna sizes at prominent macrosite locations, and so forth might hinder a smooth introduction of massive MIMO into today’s networks. For more realistic number of antennas intercell interference will probably play a significant role also in the future, especially in case an increasing number of small cells has to be integrated into the overall network. Suitable combinations of massive MIMO with well-known interference mitigation techniques like coordinated scheduling, coordinated beamforming, joint transmission precoding, or network MIMO might provide a good tradeoff between overall effort, complexity, and performance. Here, the goal is to provide a holistic top down view on powerful and practically realizable 5G system concepts and its main enablers based on the above-described techniques. Potential topics include, but are not limited to:

  • Cellular radio system concepts based on massive MIMO
  • Cooperation and coordination schemes including massive MIMO
  • Integration and comparison of massive and network MIMO
  • Concepts including top central processing like joint transmission CoMP
  • Integration of small cells into massive and/or network MIMO systems
  • Theoretical and practical performance limits for massive and network MIMO
  • Deployment concepts for massive MIMO
  • Antenna concepts allowing a smooth integration into existing macrocellular networks
  • Low profile antenna concepts
  • Realization issues and HW impairments for active antennas
  • Suitable RF frequency bands with respect to massive or network MIMO
  • Novel backhauling solutions supporting massive and network MIMO
  • Novel ideas for channel estimation and prediction, HW calibration, user tracking, and so forth
  • Benefits and concepts for multiple antennas at UE side
  • The benefit of massive MIMO in local area scenarios
  • Field trial or measurement results
