The European 5G project Mobile and Wireless Communication Enablers for the 2020 Information Society (METIS) has proposed technology components that will allow the cost efficient deployment of hundreds of antennas at cellular base stations. These technology components include fine tuning the pilot-data resource allocation trade-off for good performance, a novel random access scheme supporting many users, coded channel state information for sparse channels in frequency division duplexing systems, managing user grouping and multi-user beamforming, and a decentralized coordinated transceiver design. The aggregate effect of these components enables massive MIMO to deliver very high data rates and manage dense populations.
