What’s the difference between Single period and Dual period in 5G frame structure?
And what’s the benefit?
2.5ms single period: dddsu
2.5ms dual peripd: dddsuddsuu
I am asking or 8:2 single and dual period, what’s the benefit to choose one over the other?
They are different ratio of UL/DL slots, it is for different requirement of service.
8:2 is 5ms single period. There is option of 4:1 2.5ms single period or 7:3 2.5ms dual period. With different options downlink and Uplink transmission delay changes with high Uplink transmission delay on 8:2 of 3.3 ms and downlink transmission delay of 1.7 ms on 7:3 option. Uplink and downlink round trip delay is also highest on 8:2 of 4.95ms. Although 8:2 has high delays but it will support more SSB blocks as compared to 4:1 & 7:3. Also with high GP symbols in 8:2 cell radius is bigger as compared to other options.
