Paging early indication for a user equipment
Various aspects of the present disclosure generally relate to wireless communication.

In some aspects, the UE may receive a configuration that configures a PEI in a second initial downlink bandwidth part associated with a second category of UEs, and may monitor for a PEI in the second initial downlink bandwidth part based at least in part on the configuration. Numerous other aspects are described.
