It also decreases the guard band for the waveform, which means that 5G waveforms are not limited to 90% of the bandwidth as they are in LTE.

For symbols 0 and 7 within a slot in Normal cyclic prefix mode, $10240 T_c$ seconds are copied.

By adding the cyclic prefix, the transmitted signal will need more energy and therefore, there will be a bit rate reduction which can be overcome by choosing a symbol period greater than the cyclic prefix length.

The SubcarrierSpacing property maps the BWP to one of the SCS  Current multicarrier technique, i.e. OFDM, that is adopted in. 3GPP-LTE/LTE-A and 802.11.a/g/n uses cyclic prefix (CP) to eliminate inter-symbol interference when  There is only limited support for other applications due to the inflexibility of the waveform.

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. In the simplest case of (a), a reduced BWP is configured for a UE of a lower bandwidth capability.
