Massive MIMO in Practice: From 5G to 6G

Massive MIMO in Practice: From 5G to 6G (2nd edition of the previously titled Advanced Antenna Systems for 5G Network Deployments: Bridging the Gap between Theory and Practice) provides a theoretical introduction to Massive MIMO as well as presenting how it can meet network performance requirements for commercial deployment. This new edition will provide a thorough understanding of: array antennas and how they can be used for beamforming, null-forming, and support for MIMO features; Massive MIMO features and how they work, with a particular focus on mobile networks and the specifics relevant for mobile network operation, for example, characteristics of the radio channel in different environment and how Massive MIMO solutions adapt to these; a detailed walk-through of the 3GPP physical layer support for Massive MIMO solutions, the background for this support, and how it can be used in mobile networks; explanations of what performance can be achieved in commercially deployed mobile networks for: different antenna configurations, different Massive MIMO features, and different network deployment environments; regulatory aspects which are new and specific to Massive MIMO operation; and product architecture and implementation aspects that provide cost efficient and flexible operation. New to this edition More detail on the practical use of Massive MIMO in commercial mobile networks, specifically how to choose solutions, including antenna configuration and suitable Massive MIMO features, for cost efficient operation depending on traffic and environmental conditions A new chapter on how to put the complete Massive MIMO solution together: hardware solutions, features and use of spectrum, particularly the different use of TDD, FDD, and mm-wave Outlines promising Massive MIMO solutions to be deployed in the future Inclusion of 3GPP’s Rel. 17 and Rel. 18 updates Recent regulatory issues of high general interest Practical aspects of network planning, deployment, and operation Examples of other applications of Massive MIMO: satellites, drones, and FWA Outlines the path Massive MIMO can play to achieving 6G
