| 摘 要： | 在室内/热点区域场景下,由于终端与基站之间信道质量良好,因此可以考虑引入高阶星座调制以提高频谱效率。基于一种MCS/TBS/CQI配置,对多种Small Cell场景进行引入256QAM的系统级仿真,并通过仿真结果来对比在不同场景中,引入256QAM和采用原有调制方式对用户吞吐量、频谱效率等多项指标的影响。仿真结果初步表明,在Small Cell scenario 3稀疏场景下,引入256QAM后将对系统产生较大增益。

| Abstract: | Due to good channel quality between terminal and base station, higher order constellation modulation can be used to improve spectrum efficiency in hotspot/indoor scenarios. Based on MCS/TBS/CQI table design, several scenarios of Small Cell are introduced into 256QAM system-level simulation. Bythe simulation, 256QAM is compared with the original modulation modes in user throughput and spectrum efficiency in different scenarios. Simulation results reveal that in scenario 3 sparse; 25QNM has higher gain for system. |
