Several different waveform processing techniques have been studied and proposed for the 5G new radio (NR) physical layer, to support new mixed numerology and asynchronous services. The evaluation and comparison of these different techniques is commonly based on matched waveform processing in the transmitter and receiver units. In this article, it is shown that different techniques can be flexibly mixed, allowing to separately optimize complexity-performance trade-offs for transmitter and receiver implementations. Mixing of different waveform processing techniques is possible by setting adequate requirements for transmitter and receiver baseband processing allowing transparent design. The basic framework of how transmitter and receiver units can be independently applied and evaluated in the context of transparent design and an extensive set of examples of the achievable radio link performance with unmatched transmitter and receiver waveform processing are provided. The discussed approach and solutions simplify standardization, improve transparent transmitter and receiver coexistence, and allow future-proof evolution path for performance improvements in 5G NR physical layer hardware and algorithm design.
Mobile Communications Beyond 52.6 GHz: Waveforms, Numerology, and Phase Noise Challenge
在本文中,提供了5G新无线电(NR)物理层演进以支持超过52.6GHz通信的首要考虑因素。此外,基于OFDM和DFT-s-OFDM的网络的性能进行了评估,特别强调相位噪声(PN)引起的失真。结果表明,DFT-s-OFDM在5G NR Release 15假设下对PN更具鲁棒性,即关于支持的相位跟踪参考信号(PTRS)设计,因为它直接在时域中实现了更有效的PN缓解。为了进一步提高PN补偿能力,修改了用于DFT-s-OFDM的PTRS设计,而对于OFDM波形,引入了新的块PTRS结构,提供了与具有增强PTRS设计的DFT-s-OFDM相似的链路性能。我们证明,现有的5G NR Release 15解决方案可以扩展到支持具有增强PTRS结构的60 GHz载波频率的高效移动通信。此外,对于超过52.6GHz的通信,可以考虑用于用户数据的基于DFT-s-OFDM的下行链路,以利用更高阶的调制和编码方案来进一步提高系统功率效率和性能。最后,提供了网络链路预算和小区大小考虑,表明在具有特定发射功率调节的某些频带处,小区大小最终可以是下行链路受限的。
