Question: In a shared spectrum channel access scenario initiated by a gNB, what condition must be met for a UE to transmit an UL transmission burst immediately after detecting a DL transmission burst within the channel occupancy time, without sensing the channel?
Option 1: The gap between the UL and DL transmission bursts is more than one sensing slot duration.
Option 2: The gap between the UL and DL transmission bursts is at most one sensing slot duration.
Option 3: The UE has received explicit permission from the gNB to transmit without sensing.
Option 4: The channel occupancy time has just begun, following a successful idle channel sense by the gNB.
Explanation: According to specified conditions for shared spectrum channel access initiated by a gNB, a UE can transmit UL transmission bursts after detecting DL transmission bursts within the channel occupancy time without sensing the channel, provided that the gap between the UL and DL transmission bursts is at most one sensing slot duration. This ensures efficient use of the channel while minimizing collisions in a shared spectrum environment.
