摘要
我们研究了在细胞免除 massive MIMO 下行链路中, ultra-reliable low-latency communication(URLLC)与 enhanced mobile broadband(eMBB)的非正交共存。我们提供了一个统一的信息论框架,将基于不匹配解码的 URLLC 错误概率的有限块长分析与 eMBB 的无限块长分析的频谱效率相结合。考虑了叠加编码和三级去包装作为应对信道间干扰和 URLLC 随机激活模式的替代方案,假设在接入点处于基于准径的信道状态信息获取,用户处于统计信道知识。数值结果揭示了在不同的预编码和功率控制策略下,eMBB 与 URLLC 性能之间的权衡。
