Hi experts.
DCI 0_1 seems to have DAI fields. Although it is for scheduling PUSCH.
Anyone know why?
I am referring to Downlink Assignment Index 1 and 2.
Admin note: this post was updated with image below.
UE sends ack nack for PDSCH in PUSCH or PUCCH therefore you should have DAI bits there.
Just not sure about , if UE does not have any Downlink data that should be empty or not.
Somebody else can elaborate…
I think UE may send a dummyy PUSCH in this case.
