摘要 提出了一种面向5G密集网络部署的极简数据载波设计。极简数据载波是在C-RAN架构下的一种微蜂窝数据载波,主要用于数据承载,支持无公共信道开销、极少或者没有控制信道开销,能够有效降低密集数据载波之间信令的干扰,较大幅度提高能效,并由于设计简单有利于降低数据载波的成本。重新设计了传统数据载波的信令,并重新设计宏基站和微基站的接口和交互流程。重点解决了3个问题:微基站载波的发现和选择、用户同宏微载波的同步接入、宏微和微微载波间的测量切换。仿真结果表明,在相对理想的回传支持下,能较大幅度提升系统的切换性能、吞吐量和能效。 In this paper, we propose an ultra-lean data carrier design for dense small- - ~ cell deployment with macro coverage. An ultra-lean data carrier does not have common broadcast signaling overhead and has minimum control signaling. With such a carrier, energy consumption and interference in dense small cells can be reduced and throughput improved. Moreover, deployment cost can also be reduced. The traditional data carrier signaling is redesigned, and the interface and interaction processes of macro and micro based stations are also redesigned. Three problems have been solved in this paper: discovery and selection of micro base station carrier, synchronize access between user and macro-micro carrier, the measuring switch between macro carrier and micro carrier. Simulations show that signaling overhead, throughput, and energy efficiency significantly improve with ideal backhaul.
