What the CP does is to copy a small part of the initial information (hence the name prefix) to the end of each symbol (hence the name cyclic). Thus, the receiver can identify the end points of each symbol and correctly correlate the information, thereby eliminating the interference problem.
2018-09-26 · Supported transmission numerologies in 5G (Credit: 3GPP TS 38.211 V15.1.0 Table 4.2–1) The OFDM symbol duration and the cyclic prefix duration scale based on the numerology.
In 5G NR, there are 13 types of preamble format supported known as Format 0, Format 1, Format 2,Format 3,Format A1,Format A2,Format A3,Forma t B1, Format B2, Format B3, Format B4, Format C0, Format C1. These 13 types of preamble format can be grouped into two categories: The Bandwidth is divided into many narrow tones, where the tones are basically orthogonal to each other with no Inter-Symbol Interference (ISI) by Cyclic Prefix. In OFDM, the bandwidth can be allocated more flexibly by scaling the subcarriers, and the high-rate data is distributed onto many low-rate channels. LTE uses Cyclic-Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) waveform for downlink transmissions and DFT-Spread OFDM for uplink transmissions. On the road to 5G, the mobile communications community has witnessed abundant waveform proposals for NR. Numerology, which determines sub-carrier spacing and cyclic prefix, is also an essential BWP configuration. Some allocation scenarios are illustrated in the figure.

26 Nov 2018 Among others, LTE supports dedicated eMBMS deployments with larger intersite distance (by the introduction of new cyclic prefix of 200us),

Under CRE or CB, an offset is added to the received signal power of LPNs so that their coverage area (range) can be increased.
ISI stands for Inter Symbol Interference. In order to avoid ISI, guard interval is inserted between two OFDM symbols. This guard internal is referred as cyclic prefix (CP).

Furthermore, 5G-NR numerology does not allow to use transform lengths smaller than 128 because this would lead to non-integer cyclic prefix (CP) lengths. The 3GPP settled on using the cyclic prefix OFDM (CP-OFDM) as the waveform of choice for 5G downlink and uplink, with modulation schemes up to 256-QAM.

Using the 5G library you can explore and quantify the effects of these parameter on the out of band emissions. W-OFDM In W-OFDM, processing is performed at the beginning and end of each OFDM symbol after IFFT computation. A cyclic prefix (CP) and cyclic suffix (CS) are added to the computed OFDM symbol,

The receiver is typically configured to discard the cyclic prefix samples A CP can be used to counter the effects of multipath propagation.
