Grant based pusch transmission and configured grant based pusch transmission in nr systems operating on unlicensed spectrum

A method comprising:

• scheduling, at an access point (AP), multiple transmission time intervals (multi-TTIs) in a physical uplink shared channel (PUSCH) in an unlicensed spectrum;
• generating, at the AP, a downlink control information (DCI) to include the scheduled multi-TTIs and a hybrid automatic repeat request acknowledgement (HARQ-ACK) assessment information associated with the scheduled multi-TTIs;
• and
• transmitting, from the AP to a user equipment (UE), the DCI over the unlicensed spectrum.

A non-transitory computer-readable media (CRM) comprising computer instructions, where upon execution of the computer instructions by one or more processors of an access point (AP), causes the one or more processors to:

• schedule multiple transmission time intervals (multi-TTIs) in a physical uplink shared channel (PUSCH) in an unlicensed spectrum;
• generate a downlink control information (DCI) to include the scheduled multi-TTIs and a hybrid automatic repeat request acknowledgement (HARQ-ACK) assessment information associated with the scheduled multi-TTIs;
• and
• transmit the DCI to a user equipment (UE) device over the unlicensed spectrum.
