What is the behavior of UE if Scell Rach fails?
Hi Jagan,
Irrespective of any Cell RACH, if RACH failed at UE side, it will initiate an Reestablishment procedure to available cell. This is standard procedure at UE for RACH failures. So maybe in your case aswell UE initiate an Reestablishment.
Pcell will be expecting the HARQ feedback of Scell but UE failed to decode the Scell PDCCH . This case UE doesn't send the CA HARQ and uses different PUCCH format But PCELL will be expecting different format to receive the feedback. How to overcome this issue.
If SR Resource is not configured then UE triggers RACH to acquire UL grant, but if RACH fails or fails to receive UL grant?
