Claim 0:
1. An apparatus for a user equipment (UE) configured for operation in a Fifth Generation New Radio (5G NR) network, the apparatus comprising:
processing circuitry, wherein to configure the UE for small data transmission (SDT) in the 5G NR network, the processing circuitry is to:
detect while in a Radio Resource Control Inactive (RRC_Inactive) state, a radio link failure during a first SDT of uplink (UL) data to a base station;
generate a secure key for a second SDT based on the radio link failure;
encode a configuration message for transmission to the base station, the configuration message including an indication of the second SDT;
decode a response message from the base station, the response message including a UL grant; and
encode the UL data for the second SDT, the UL data encoded using the secure key, and the second SDT performed using the UL grant while the UE is in the RRC_Inactive state; and

a memory coupled to the processing circuitry and configured to store the secure key.
