Enhanced RACH (random access channel) design for 5G Clot (cellular internet of things)

A method, comprising:

• receiving random access (RA) resource allocation information via one of a system information message or a downlink control information (DCI) message;
• selecting a RA preamble sequence;
• generating a payload indicating a cell radio network temporary identifier (C-RNTI) of a UE;
• transmitting to a base station, based on the RA resource allocation information, a first message including a RA message comprising the RA preamble sequence and the payload;
• and
• receiving a response to the RA message comprising a second message with the C-RNTI of the UE and a resource allocation indicating that the RA message was successfully received by the base station.

A baseband processor configured to perform operations comprising:

• receiving random access (RA) resource allocation information via one of a system information message or a downlink control information (DCI) message;
• selecting a RA preamble sequence;
• generating a payload indicating a cell radio network temporary identifier (C-RNTI) of a UE;
• transmitting to a base station, based on the RA resource allocation information, a first message including a RA message comprising the RA preamble sequence and the payload;
• and
• receiving a response to the RA message comprising a second message indicating the C-RNTI of the UE and a resource allocation indicating that the RA message was successfully received by the base station.
