Convergent Communication, Sensing and Localization in 6G Systems: An Overview of Technologies, Opportunities and Challenges (2021, background): “Beamforming can be categorized into analog, digital, and hybrid beamforming [46], where the former supports a single stream and phase shifters allow directional transmission (depending on the aperture), while the second option allows multiple streams in different directions.”
A Survey on Millimeter-Wave Beamforming Enabled UAV Communications and Networking (2021, background): “For example, different from conventional analog/hybrid beamforming architecture based on phase shifters, switch-based architecture replaces phase shifters with switches to further reduce the hardware complexity and power consumption, at the expense of communication performance [15].”
Joint Design of Communication and Sensing for Beyond 5G and 6G Systems (2021, background): “While in lower frequencies digital beamforming is common in 5G, at the higher carrier frequencies, often digitally-controlled analog or hybrid beamforming is employed [46].”
A Comprehensive Survey on Millimeter Wave Communications for Fifth-Generation Wireless Networks: Feasibility and Challenges (2020, background): “Beamforming is an antenna technique, which steers, predominantly signals formed from an array of transmit antennas to a desired angular direction [7], [72].”
