Indication of unsuccessful hybrid automatic repeat request termination for uplink communication

A network node, comprising:

• a processing system that includes processor circuitry and code-storing memory circuitry, the processing system configured to cause the network node to:
• transmit a downlink control information (DCI) message associated with scheduling a new transport block (TB) on a physical uplink shared channel, wherein the DCI message includes a feedback indication of a previous TB;
• and
• receive one or more uplink communications, wherein whether the one or more uplink communications includes a retransmission of information associated with the previous TB is based on the feedback indication.

A UE, comprising:

• a processing system that includes processor circuitry and code-storing memory circuitry, the processing system configured to cause the UE to:
• receive a non-scheduling downlink control information (DCI) message, wherein the non-scheduling DCI message includes an automatic repeat request (ARQ) feedback indication of a previous transport block (TB) scheduled in a physical uplink shared channel (PUSCH) and scheduled by a previous DCI message, wherein the non-scheduling DCI message includes a configuration associated with validation of the non-scheduling DCI message;
• and
• transmit one or more uplink communications to re-transmit information associated with the previous TB based on the feedback indication.
