Type 3 hybrid automatic repeat request acknowledgment

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors coupled to the memory, the one or more processors configured to:
• receive a downlink control information (DCI) message, the DCI message including at least a first field and a second field, the first field indicating a request for Type 3 hybrid automatic repeat request (HARD) acknowledgment (HARQ-ACK), the second field indicating a physical downlink shared channel (PDSCH) communication is not scheduled when a value of the second field includes:
• all zeros if resource allocation Type 0 is configured,
• all ones if resource allocation Type 1 is configured, or
• all ones or all zeros if both the resource allocation Type 0 is configured and the resource allocation Type 1 are configured;
• and
• transmit the Type 3 HARQ-ACK based at least in part on the DCI message.

An apparatus for wireless communication, comprising:

• means for receiving a downlink control information (DCI) message, the DCI message including at least a first field and a second field, the first field indicating a request for Type 3 hybrid automatic repeat request (HARD) acknowledgment (HARQ-ACK), the second field indicating a physical downlink shared channel (PDSCH) communication is not scheduled when a value of the second field includes:
• all zeros if resource allocation Type 0 is configured,
• all ones if resource allocation Type 1 is configured, or
• all ones or all zeros if both the resource allocation Type 0 is configured and the resource allocation Type 1 are configured;
• and
• means for transmitting the Type 3 HARQ-ACK based at least in part on the DCI message.

A non-transitory computer-readable medium storing a set of instructions for wireless communication includes one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:

• receive a downlink control information (DCI) message, the DCI message including at least a first field and a second field, the first field indicating a request for Type 3 hybrid automatic repeat request (HARD) acknowledgment (HARQ-ACK), the second field indicating a physical downlink shared channel (PDSCH) communication is not scheduled when a value of the second field includes:
• all zeros if resource allocation Type 0 is configured,
• all ones if resource allocation Type 1 is configured, or
• all ones or all zeros if both the resource allocation Type 0 is configured and resource allocation Type 1 are configured;
• and
• transmit the Type 3 HARQ-ACK based at least in part on the DCI message.
