Configuration information for an inactive state
Apparatuses, methods, and systems are disclosed for transmitting and/or receiving configuration information for an inactive state. One method includes receiving configuration information for a radio bearer. The method includes transitioning the radio bearer to an inactive state and configuring the radio bearer based on the configuration information. The configuration information configures the radio bearer with: a first configuration that transmits data in the inactive state in response to a data property being less than a predetermined threshold; a second configuration that initiates transition from the inactive state to a connected state before transmitting data; a third configuration that transmits data in the inactive state and initiates transition from the inactive state to the connected state after at least a portion of the data is transmitted; and/or a fourth configuration that inhibits data transmission in the inactive state and inhibits initiating transition from the inactive state to the connected state.

predetermined physical resources for transmitting while in the inactive state;
a predetermined format for transmitting while in the inactive state; and

8. The method of claim 1 , further comprising:
receiving a message, wherein the message comprises information used to configure a logical prioritization order, and the information indicates an order of priority for a buffer status report, data, and radio resource control signaling;
configuring the logical prioritization order based on the information; and
performing transmissions based on the logical prioritization order.

a first indication indicating that the additional data is available to be transmitted and a data size of the additional data is less than the data threshold parameter; and
a second indication indicating that the additional data is available to be transmitted and the data size of the additional data is greater than the data threshold parameter;
wherein the processor compares a buffer occupancy of anticipated data with the data threshold parameter, and the indication is selected based on the comparison of the buffer occupancy of the anticipated data with the data threshold parameter.
