AI Technical Summary
In 5G NR communication technology, CP-OFDM systems are susceptible to frequency and time offsets between adjacent subbands, leading to inter-subband interference. Furthermore, inserting guard bandwidth wastes frequency resources, and existing technologies have not been able to effectively solve this problem.
N frequency domain resource blocks are divided into two groups and distributed alternately in the frequency domain. The bandwidth of each group of frequency domain resource blocks is different. Windowing or filtering is performed using waveform functions with different parameters. The bandwidth of frequency domain resource blocks in the same group is equal. Data sequence is formed by inverse Fourier transform to avoid interference between adjacent frequency domain resource blocks in the same group.
It reduces the complexity of data sequence filtering, effectively avoids inter-subband interference, and improves the efficiency of frequency resource utilization.
