Multiple TTI PUSCH transmissions in a wireless communication system

An apparatus, comprising:

• a memory;
• and
• at least one processor in communication with the memory, wherein the at least one processor is configured to:
• receive radio resource control (RRC) signaling from a network entity to configure identify a data structure that includes one or more sets of physical uplink shared channel (PUSCH) transmission configurations, wherein the data structure is defined using abstract syntax notation one (ASN.1) and includes a time domain allocation list parameter, and wherein the time domain allocation list parameter specifies at least one of a maximum number of PUSCH transmission allocations, a K2 value, a PUSCH mapping type, or a start and length indicator value (SLIV);
• receive, from the network entity, a downlink control information (DCI) message, wherein the DCI message includes a time domain resource assignment field (TDRA), new data indicators (NDIs) corresponding to PUSCH transmissions, and a single priority class information field, wherein a value of the TDRA indicates a set of PUSCH transmission configurations included in the data structure;
• and
• perform the PUSCH transmissions spanning a single or multiple slots over an unlicensed band according to the indicated set of PUSCH transmission configurations and a priority class indicated in the priority class information field.

A non-transitory computer readable memory medium storing program instructions executable by processing circuitry to cause a user equipment device (UE) to:

• receive radio resource control (RRC) signaling from a network entity to identify a data structure that includes one or more sets of physical uplink shared channel (PUSCH) transmission configurations, wherein the data structure is defined using abstract syntax notation one (ASN.1) and includes a time domain allocation list parameter, and wherein the time domain allocation list parameter specifies at least one of a maximum number of PUSCH transmission allocations, a K2 value, a PUSCH mapping type, or a start and length indicator value (SLIV);
• receive, from the network entity, a downlink control information (DCI) message, wherein the DCI message includes a time domain resource assignment field (TDRA), new data indicators (NDIs) corresponding to PUSCH transmissions, and a single priority class information field, and wherein a value of the TDRA indicates a set of PUSCH transmission configurations included in the data structure;
• and
• perform the PUSCH transmissions spanning a single or multiple slots over an unlicensed band according to the indicated set of PUSCH transmission configurations and a priority class indicated in the priority class information field.
