NR eNB will not send an ACK/NACK . So UE should hold the buffer untill it receives same HARQ process DCI0. How long it hold if eNB delays the Scheduling same HARQ process?
Hi Jaganathan,
It is depends on the UE implementation. But at least it should hold untill HARQ RTT timer. As UL HARQ is based SF so eNB has to do new or re transmission is shorter time. if in worst case eNB holds then UE also should hold the HARQ buffer untill MAC reset happens or reconfiguration happens.
Reestablishment triggers after Source cell is detected as Radio ink failure, If UE is not able to detect any other cell during this time how long it can wait to find new cell to trigger Reestablishment .
If HO fails the UE will initiate contention based reestablishment and connect to some ENB, But target ENB have provided the contention free Rach preamble , at failure case how long ENB will hold this preamble because it has to release for other UE?
In LTE it is fixed as 4ms in FDD, How UE decides this timing in NR?
