论文摘要
超大型多输入多输出（XL-MIMO）系统是一个新概念，其中空间非平稳性允许激活大量的用户设备（UES）。本文重点介绍了新型XL-MIMO频道方案中基于赠款的随机访问（RA）方法。经典最强用户碰撞分辨率（SUCRE）协议中的修改已汇总，以探索XL-MIMO中的可见性区域（VRS）重叠。拟议的基于赠款的RA协议利用了这种新的自由度来改善访问尝试和接受的UES的数量。结果，提出的针对XL-MIMO系统的基于赠款的协议能够降低飞行员分配步骤中的延迟。
Extra-large massive multiple-input multiple-output (XL-MIMO) systems is a new concept, where spatial non-stationarities allow activate a high number of user equipments (UEs). This paper focuses on a grant-based random access (RA) approach in the novel XL-MIMO channel scenarios. Modifications in the classical Strongest User Collision Resolution (SUCRe) protocol have been aggregated to explore the visibility regions (VRs) overlapping in XL-MIMO. The proposed grant-based RA protocol takes advantage of this new degree of freedom for improving the number of access attempts and accepted UEs. As a result, the proposed grant-based protocol for XL-MIMO systems is capable of reducing latency in the pilot allocation step.
