7. A user equipment (UE), comprising:
a transceiver configured to communicate with a network; and
a processor communicatively coupled to the transceiver and configured to:
collect access barring information to perform an access barring procedure corresponding to a cell, wherein the information includes an access identity of the UE;
receive a slice specific random access prioritization configuration from the cell;
receive a legacy random access prioritization configuration from the cell;
perform the access barring procedure using the access barring information;
select a random access prioritization configuration to use for a random access channel (RACH) procedure from a set of the slice specific random access prioritization configuration and the legacy random access prioritization; and
perform the RACH procedure with the cell using the selected random access prioritization configuration.
