LTE ENB gives aggregated LC grant to UE, and UE applies LCP, is it same in NR ?
How UE sends MSG3 in less grant? Will it wait for NEB to give grant or UE does one more RACH?
If no SR is configured at UE side, then IF UE triggeres RACH then what will be the MSG3 content? How ENB knows UE is triggering an RACH for UL grant?
