Each position in the bitmap represents a Primary RAT.
If a bit is set to "1", the respective RAT is restricted for the UE.
If a bit is set to "0", the respective RAT is not restricted for the UE.
Bits 11-15 reserved for future use.
The Primary RAT is the RAT used in the access cell, or target cell.

Secondary RAT Restriction | M | | BIT STRING {
e-UTRA (0),
nR (1), e-UTRA-unlicensed (2), nR-unlicensed (3)}
(SIZE(8, …)) |
Each position in the bitmap represents a Secondary RAT.
If a bit is set to "1", the respective RAT is restricted for the UE.
If a bit is set to "0", the respective RAT is not restricted for the UE.
Bits 4-7 reserved for future use.
A Secondary RAT is a RAT, distinct from the UE's primary RAT, used in any cell serving the UE excluding the PCell.
