Inactive direct transmission from user equipment (ue) via random access channel (rach) procedure

A User Equipment (UE) device, comprising:

• communication circuitry;
• and
• a processor configured to perform operations comprising:
• in response to a determination to perform a Radio Resource Control (RRC) inactive data transmission:
• transmitting, via the communication circuitry, a message 1 (Msg1) or a message A (MsgA) preamble based on a Random Access Channel (RACH) configuration for the RRC inactive data transmission;
• transmitting, via the communication circuitry a message 3 (Msg3) or a MsgA Physical Uplink Shared Channel (PUSCH) comprising uplink (UL) data via configured resources;
• and
• receiving, via the communication circuitry, a message 4 (Msg4) or a message B (MsgB) in response to the Msg3 or the MsgA PUSCH.

A baseband processor, comprising:

• a memory interface;
• and
• processing circuitry communicatively coupled to the memory interface and configured to perform operations comprising:
• suspending a Random Access Channel (RACH) procedure for a Radio Resource Control (RRC) inactive data transmission;
• and
• generating a RRC resume request.
