论文摘要
本文研究了在5G加速或以后在6G中使用以上71GHz频率的潜力。更具体地说，重点是分析从波形和命理性方面所需的内容。结果表明，在移动71GHz以上时可能需要更高的基线子载波间距（SCS），以满足需要更高必需的带宽和相位噪声稳健性的需求。所需的SCS取决于载波频率和调制顺序。还可以说明，单载波波形，尤其是已知的尾部离散傅里叶变换正交频率分级多路复用（KT-DFT-S-OFDM）波形波形是潜在的候选者，可用于5G加速度或6G，用于子THZ频率，因为其稳健性，用于相位噪声，降低输出电力后退和稳定的尾部和尾部的适应性。
This paper studies the potential of using above 71GHz frequencies for 5G-Advanced or later in 6G. More specifically, the focus is to analyze what could be needed in terms of waveform and numerologies. The results suggest that higher baseline subcarrier spacings (SCSs) may be needed when moving above 71GHz, to fulfill the need for higher required bandwidths and phase noise robustness. The required SCS depends on carrier frequency and modulation order. It is also illustrated that single-carrier waveforms, especially Known Tail Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (KT-DFT-s-OFDM) waveform is a potential candidate to be used in 5G-Advanced or 6G for sub-THz frequencies due to its robustness to phase noise, lower output power back-off and flexible adaptation of head and tail lengths.
