  • Publication number: 20240292460
    Abstract: A user equipment (UE) may be configured/scheduled with uplink (UL) transmissions over multiple channels. Each UL transmission is aligned with a boundary of a UE fixed period frame (FFP). For each UL transmission, the UE may determine whether a gNB has initiated a channel occupancy time (COT) in a gNB FFP over a corresponding channel. If the COT is not initiated, the UE may initiate a COT in the UE FFP over the channel when the channel is available, by transmitting a corresponding UL transmission over the channel in the UE FFP. The UE may send, to the gNB, information indicating UE-initiated COT channel(s) of the multiple channels over which COT(s) have been initiated by the UE. The gNB may provide feedback for the UL transmissions based on the information.
