Abstract
An O-RU may receive a PRACH preamble and a PUSCH within a plurality of symbols of a slot, the PRACH and the PUSCH having different numerology. The O-RU may filter a PUSCH CP for each symbol of the PRACH preamble through a FFT window per symbol of the PRACH preamble, the FFT window extending from the end of the PUSCH CP within a symbol to the end of the symbol, and perform FFT per the FFT window of each symbol of the PRACH preamble. The O-RU may extract I/Q data in frequency domain corresponding to the PRACH preamble, adjust phase shift of the extracted I/Q data to generate the I/Q data of the PRACH preamble accounting for shift of the each FFT window in time domain compared to FFT windows of PRACH CP filtered PRACH preamble and send the I/Q data of the PRACH preamble to an O-DU.
