UE advertises SRVCC support through the FGI bits. UE also advertises if it supports other lower RAT's (2G/WCDMA) through the capability information. Based on this NW can decide on the support of CSFB/SRVCC from UE perspective.
In LTE it is fixed as 4ms in FDD, How UE decides this timing in NR?
Is it same as Pcell BWP or different from Pcell. If it is different then How UE knows which BWP to use BWP
