Multi-antenna technology for 5G and beyond


Erik Dahlman
Ericsson, Sweden



Abstract

The first release of 5G/NR wireless-access technology is now being commercially deployed with 3GPP standardization focusing on the evolution of 5G. Compared to earlier generations of wireless communication, multi-antenna transmission play a much more important role in 5G. This is especially true for operation in higher frequency bands where the use of beam-forming is critical to ensure sufficient coverage. However, multi-antenna technology is important also for lower frequencies as a tool to enhance the radio-access efficiency in terms of system capacity and achievable data rates. This talk will provide an overview of 5G/NR multi-antenna technology, including current status as well as the expected evolution in future NR releases and beyond.
