用于非相干联合传输的集中式和分布式解调器

Centralized and distributed schedulers for non-coherent joint transmission

Shangbin Wu, Yinan Qi

摘要:

本文研究了三种典型的网络协调方案的性能,动态点选择、完全重叠非相干联合传输(F-NCJT)和非完全重叠NCJT(NF-NCJT)。这些方案中的每一个都需要根据集中式或分布式调度器在协调的传输接收点(TRP)之间交换不同级别的用户数据和信道状态信息(CSI)报告。简要讨论了这些网络协调方案的调度策略。已经证明分布式网络协调方案(例如,NFNCJT)仍然可以相当好地执行;这一结果对第五代(5G)蜂窝网络架构的设计具有重要意义。

英文摘要:

This paper studies the performance of three typical network coordination schemes, i.e., dynamic point selection, fully overlapped non-coherent joint transmission (F-NCJT), and nonfully overlapped NCJT (NF-NCJT), in 3GPP new radio (NR) in indoor scenarios via system level simulation. Each of these schemes requires a different level of user data and channel state information (CSI) report exchange among coordinated transmission reception points (TRPs) depending on centralized or distributed schedulers. Scheduling strategies of these network coordination schemes are briefly discussed. It has been demonstrated that distributed network coordination schemes (e.g., NFNCJT) can still perform reasonably well; a result which has important implications to the design of the fifth generation (5G) cellular network architecture.
