Methods and apparatuses for a physical uplink shared channel (PUSCH) repetition enhancement mechanism for a time division duplex (TDD) scenario

A base station for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory, the at least one processor configured to cause the base station to:
• transmit downlink control information (DCI) including a time domain resource assignment field;
• determine, based at least in part on the time domain resource assignment field, whether each uplink (UL) slot of a set of UL slots satisfies a condition associated with transmission of a physical uplink shared channel (PUSCH) transmission of a set of PUSCH transmissions, wherein:
• the set of UL slots includes a special type slot including at least one downlink (DL) symbol,
• the special type slot includes a set of consecutive symbols in a time domain,
• the condition is that a maximum symbol total number of the set of consecutive symbols is greater than or equal to a sum of a configured value and a value associated with receiving-transmission transition time, and
• the value associated with receiving-transmission transition time is greater than 0;
• select, based at least in part on the time domain resource assignment field, a respective one or more time domain resources from each UL slot of the set of UL slots that satisfies the condition;
• and
• receive UL data via the selected respective one or more time domain resources in each UL slot of the set of UL slots that satisfies the condition, the UL data corresponding to the set of PUSCH transmissions.

A method performed by a user equipment (UE), the method comprising:

• receiving downlink control information (DCI) including a time domain resource assignment field;
• determining, based at least in part on the time domain resource assignment field, whether each uplink (UL) slot of a set of UL slots satisfies a condition associated with transmission of a physical uplink shared channel (PUSCH) transmission of a set of PUSCH transmissions, wherein:
• the set of UL slots includes a special type slot including at least one downlink (DL) symbol,
• the special type slot includes a set of consecutive symbols in a time domain,
• the condition is that a maximum symbol total number of the set of consecutive symbols is greater than or equal to a sum of a configured value and a value associated with receiving-transmission transition time, and
• the value associated with receiving-transmission transition time is greater than 0;
• selecting, based at least in part on the time domain resource assignment field, a respective one or more time domain resources from each UL slot of the set of UL slots that satisfies the condition;
• and
• transmitting UL data via the selected respective one or more time domain resources in each UL slot of the set of UL slots that satisfies the condition, the UL data corresponding to the set of PUSCH transmissions.
