METHOD AND APPARATUS FOR DETERMINING SIDELINK HYBRID AUTOMATIC REPEAT REQUEST ACKNOWLEDGEMENT (HARQ-ACK) FEEDBACK TRANSMISSION OCCASIONS

原文（中国語）

Embodiments of the present disclosure relate to methods and apparatuses for determining sidelink HARQ-ACK feedback transmission occasions over unlicensed spectrums. According to some embodiments of the disclosure, a UE may: perform a first channel access procedure to initiate a first COT; determine a first PSFCH occasion inside of the first COT; determine whether there is HARQ-ACK feedback to be transmitted in the first PSFCH occasion; and in response to determining that there is HARQ-ACK feedback to be transmitted in the first PSFCH occasion, leave gap symbols for the first PSFCH occasion within the first COT blank, or in response to determining that no HARQ-ACK feedback is to be transmitted in the first PSFCH occasion, perform continuous transmissions in the first PSFCH occasion.
