The receiver is typically configured to discard the cyclic prefix samples A CP can be used to counter the effects of multipath propagation. Xiaoming Chen, in 5G Physical Layer, 2018. 2.2.2 Waveform. NR employs cyclic prefix OFDM (CP-OFDM) in both uplink and downlink up to at least 52.6 GHz. This is in contrast to LTE, where CP-OFDM is only used for downlink transmissions and DFT-Spread OFDM (DFTS-OFDM) is used for uplink transmissions. Some of the 5G waveform candidates (e.g, FBMC) tries to completely remove it, but many of the Candidate still use the cyclic prefix with various length.

If you see the below table from technical specification 38.211, 5G supports 5 types of cyclic prefixes. Cyclic prefix in 5G 5G supports 5 types of Subcarrier spacing and cyclic prefix. Accept numerology 2 i.e subcarrier spacing 60 kHz all are normal cyclic prefix. the cyclic prefix belonging to the delay spread component and discards a section of the main body of the ODFMA symbol which has a duration equal to the cyclic prefix The time domain representation of each delay spread component within the processing window is different (as shown in Figure 26).

On the road to 5G, the mobile communications community has witnessed abundant waveform proposals for NR. Most proposals, being multi-carrier waveforms, are either variations on CP-OFDM. 2019-05-29 2020-04-22 What is cyclic prefix (CP) In the OFDM symbol transmission,ISI occurs at the receiver due to delay spread of the channel.
