Abstract
A method is disclosed in which a user equipment (UE) that communicates with a radio access network (RAN) maintains information for configuring timing of fixed frame period (FFPs) for a listen-before-talk (LBT) procedure. When the UE has data to be transmitted, it performs a clear channel assessment, CCA, to determine if a communication channel is clear. When the CCA indicates that the communication channel is clear a channel occupancy time, COT, is initiated for the UE within a subsequent FFP and transmission of the data commences. However, transmission of the data ceases following receipt of an indication, from a node of the RAN, that the transmission should be stopped.
