Patent ID: 11102764

Abstract:
User equipment (UE) includes processing circuitry. To configure the UE for early data transmission (EDT), the processing circuitry is to encode a physical random access channel (PRACH) preamble for transmission to a base station as a PRACH procedure Message 1 (MSG1), the PRACH preamble including a request for EDT. A random-access response (RAR) message is decoded, the RAR message received from the base station as a PRACH procedure Message 2 (MSG2) and including an uplink (UL) grant for the EDT with a transmission block size (TBS) indicator. A TBS is selected from a plurality of available TBSs corresponding to the TBS indicator. UL data is encoded for the EDT to the base station as a PRACH procedure Message 3 (MSG3) using the UL grant and the selected TBS.
