1. An apparatus for wireless communication, comprising:
at least one processor configured to cause a base station to:
generate and transmit radio resource control (RRC) signaling to transition a wireless device to a RRC inactive state from a RRC connected state, wherein the RRC signaling includes a configuration of physical resources for data transmission in the RRC inactive state;
exchange data communication with the wireless device while the wireless device is in the RRC inactive state, wherein exchanging the data communication includes receiving uplink data using the physical resources and one of a pre-configured grant or a random access channel (RACH) procedure; and
receive a first transmission of uplink data communication including an inactive radio network temporary identifier (I-RNTI), wherein a timer associated with the data communication with the wireless device while the wireless device is in the RRC inactive state starts at the first transmission, wherein the data communication with the wireless device while the wireless device is in the RRC inactive state ends when the timer expires.
