Abstract: 6G has raised a global research wave. To meet the ever-increasing demand for data transmission rates, expanding the bandwidth and increasing the number of antennas are direct and effective means. Driven by 6G application scenarios and key capabilities, 6425~7125 MHz frequency-band (U6G) extra-large scale multiple-input multiple-output (MIMO) technology becomes a candidate enabler to meet the requirements of 6G. Based on the RF and channel characteristics, the overall design goal of efficient U6G extra-large scale MIMO is proposed, to address the challenges in cost, overhead, and complexity. Finally, future research trends are discussed.
