为了满足不断攀升的数据传输速率需求，扩大频带宽度、增加天线数量是直接有效手段。在6G应用场景与关键能力的驱动下，6 425～7 125 MHz频段（U6G）超大规模多输入多输出（MIMO）技术成为满足6G需求的潜在使能技术之一。基于U6G超大规模MIMO系统的天线形态及信道特征，针对该技术面临的成本、开销、复杂度三重挑战，提出高效能U6G超大规模MIMO无线传输的总体设计目标，并展望其未来研究趋势。
Abstract：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, the 6 425 ～ 7 125 MHz frequency-band(U6G) extralarge 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.
