CCE is limited in RB's, Then how ENB allocates CCE to all the UE?
What is the priority order of LC's such as (CRNTI MAC CE,BSR MAC CE,PHR MAC CE,PHR MAC CE,CCCH etc) In 4G it is CCCH/C-RNTI MAC CE -> BSR MAC CE -> PHR MAC CE and what about 5G?
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?
