What is the maximum number of subcarriers allowed in 5G NR?

5G NR can choose subcarrier spacing from 15kHz to 240kHz, with a maximum 3300 subcarriers in simultaneous use on one channel. However, channels can be no more than 400MHz wide. The standard is frequency agnostic, meaning any subcarrier configuration can be used on any band.

What is 5G cyclic prefix?

Me: Extended CP (Cyclic Prefix), ECP, refers to the usage of longer guard period between symbols than normal CP (NCP). The NCP is specified for all SCS whereas the ECP is currently only specified for the 60 kHz SCS.

What is subcarrier spacing in 5G?

Subcarriers in cellphones, LTE 4G and 5G NR

In LTE, each subcarrier is spaced 15 kHz apart. These subcarriers are combined in groups of 12 to form a single resource block. Each resource block is used in an OFDMA arrangement to send data to different handsets or combined for high-speed data.

How is cyclic prefix calculated?

Therefore, the number of samples allocated for cyclic prefix can be calculated as Ncp=Tcp*N/T, where N is the FFT/IFFT length, T is the IFFT/FFT period and Tcp is the duration of cyclic prefix.

Which subcarrier spacing is not supported for 5G?

All other Sub-carrier spacing are supported for data and signaling except 60 KHz which is for data Physical channels only.

What should be the length of cyclic prefix?

In LTE, the normal CP duration is 7% of the core OFDM symbol (i.e., samples and samples). Figure 5.6. Cyclic prefix is inserted to avoid intersymbol interference due to the multipath channel.
