1. A method of wireless communication performed at a user equipment (UE), the method comprising:
outputting, for transmission, a mobility management request indicating that the UE supports coverage-level-based paging carrier selection;
obtaining, based on the mobility management request, a first system information block (SIB) indicating one or more coverage levels the UE is authorized to use;
obtaining, based on the mobility management request, a second SIB indicating a plurality of paging carriers, a discontinuous reception (DRX) cycle length for each of the plurality of paging carriers, and one or more coverage levels supported by the plurality of paging carriers;
selecting a first paging carrier from a subset of one or more paging carriers based on:
the one or more coverage levels indicated in the first SIB,
the plurality of paging carriers indicated in the second SIB,
a DRX cycle of the UE, and
the DRX cycle length for each of the plurality of paging carriers in the second SIB,
wherein the first paging carrier is associated with a first coverage level of the one or more coverage levels indicated in the first SIB, wherein the subset supports the first coverage level; and
obtaining a paging message via the first paging carrier based on the first coverage level.
