What is symbol duration in 5G?
5G air-2 YJS 6. SubCarrier Spacings. In LTE : SCS = 15 kHz (the OFDM symbol duration = 66.7 μs w/o CP) 5G introduces a scalable numerology with SCS with Δf = 2. μ
What is the duration of each frame in 5G?
5G NR retains the concept of 10 millisecond frame divided into 10 one-millisecond subframes. There is also a concept of slot, but its definition is different from a slot in LTE. One slot is defined as 14 OFDM symbols, which corresponds to once a frame or one millisecond in LTE.
What is OFDM symbol in 5G?
In OFDM, useful symbol time Tu and subcarrier spacing Δf are related by the equation: Tu = 1/Δf. Because 5G NR defines five Δf values (15, 30, 60, 120 and 240 kHz) in Phase 1, OFDM useful symbol times Tu's will be halved when Δf value is doubled.
Is frame duration is fixed in 5G?
Frame Length is fixed to be 10 ms. Scalable numerology should allow the subcarrier spacing from 15 Khz to 480 Khz.
