TSG-RAN WG4 Meeting Recap on Antenna Parameters
During the TSG-RAN WG4 Meeting #94-e-Bis, discussions focused on antenna parameters for different scenarios and frequency ranges. Agreements were reached on wide area coverage and additional parameters for AAS antennas. Detailed analysis was presented on elements, beamwidth, gain, and configurations of antennas in various GHz ranges. References to key documents and simulation parameters were also provided by industry experts.
