Question: What action does a User Equipment (UE) take when it receives a DCI for a PUSCH transmission with a higher UL channel access priority class value than its ongoing Type 1 channel access procedure?
Option 1: The UE may transmit the PUSCH using the ongoing Type 1 channel access procedure.
Option 2: The UE shall terminate the ongoing channel access procedure and initiate a new one for the PUSCH transmission.
Option 3: The UE shall terminate the ongoing channel access procedure but can still use it for the subsequent PUCCH transmission.
Option 4: The UE ignores the priority class value difference and continues with the PUSCH transmission as scheduled.
Explanation: According to specified conditions, if a new DCI indicates a higher priority than an ongoing Type 1 UL channel access procedure, the UE must terminate it. This ensures efficient spectrum use by prioritizing transmissions. Thus, upon receiving a DCI with a higher UL channel access priority class value for a PUSCH transmission, the UE's correct action is to terminate the ongoing procedure and potentially initiate a new one tailored to the new transmission's requirements.
