GRANT BASED PUSCH TRANSMISSION AND CONFIGURED GRANT BASED PUSCH TRANSMISSION IN NR SYSTEMS OPERATING ON UNLICENSED SPECTRUM

摘要

Systems, apparatuses, methods, and computer-readable media are provided for a wireless communication on an unlicensed spectrum. An access point (AP) of the wireless communication system includes a processor circuitry, and radio front end circuitry coupled to the processor circuitry. The processor circuitry is configured to schedule multiple transmission time intervals (multi-TTIs) in a physical uplink shared channel (PUSCH) in the unlicensed spectrum. The processor circuitry is configured to generate a downlink control information (DCI) to include the scheduled multi-TTIs and a hybrid automatic repeat and request acknowledgement (HARQACK) assessment information associated with the scheduled multi-TTIs. The radio front end circuitry is configured to transmit the DCI to a user equipment (UE) over the unlicensed spectrum.
