Question about CBG (code block group) retransmissions in 5G.
Say we have a TB scheduled in 5G that failed to be decoded by UE.
Inside that TB there are 24 CB(code blocks) among those 24, 22 were decoded correctly where as 2 failed to be decoded (I see that UE tries 16 times to decode them but still fails).
My question is: how gNB knows which 2CB failed to be decoded among the 24 sent?
Will this 2 CBs be included in a new transmission and will NDI bit will be toggled or not?
