It is depends on the release which UE supports and technology he uses. say E.g normal commercial UE which supports Dual connectivity then following is possible .
Dual connectivity MENB + SENB = MENB (max 5 CC) + SCENB (Max 5 CC) = 10CC total.
all 10 CC is supporting MIMO then each CC can support 2TB then total of 20TB's are possible theoretically .But practically no one supports more than 3CC at UE side. If it is NBIOT, BE/CL , MTC , V2X UE then above will not be applicable.
