UE retransmission issue

[Jiacheng188]

Dear author, the code in NRMacUE::handleSelfMessage indicates that if there is no retransmission, the normal scheduling can be performed. I wonder if the size of the MAC PDU needed to be retransmitted and the current granted bytes are considered in the retransmission procedure?

I would say that the retransmission procedure is carried out like the normal scheduling procedure. The gNB's scheduler assigns a grant whose size depends on the MAC PDU size to be retransmitted and the latest CQI.
