1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving, from a base station (BS), a paging communication while the UE is in an inactive mode or an idle mode;
transmitting, to the BS and based at least in part on receiving the paging communication, a first communication as part of a random access channel (RACH) procedure;
receiving, from the BS and based at least in part on transmitting the first communication, a second communication, comprising a random access message, that includes:
small mobile-terminated downlink data,
an indication of an uplink resource, and
a radio resource control (RRC) release message that causes the UE to remain in the inactive mode or the idle mode while receiving the small mobile-terminated downlink data; and
transmitting, to the BS and while in the inactive mode or the idle mode, mobile-originated uplink data using the uplink resource.
