A user equipment for wireless communication in a communication system supporting semi-static channel access, said apparatus comprising at least one processor; and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the user equipment at least to perform: monitoring for presence of a clearance indication provided by a base station device serving a user equipment device, which indicates that the base station device does not intend to communicate in a subsequent channel occupancy time of a base station device frame period and clearance for communication by the user equipment device in at least one idle period of the base station device frame period, disabling communication by the user equipment device in the at least one idle period of the base station device frame period when the monitoring yields absence of the clearance indication, or enabling communication by the user equipment device in the at least one idle period of the base station device frame period when the monitoring yields presence of the clearance indication; and inhibiting observation of at least some downlink transmissions by and/or downlink channels from the base station device in at least part of a subsequent channel occupancy time of the base station device frame period when the monitoring yields presence of the clearance indication, or performing observation of at least some downlink transmissions by and/or downlink channels from the base station device in at least part of a subsequent channel occupancy time of the base station device frame period when the monitoring yields absence of the clearance indication. at least one processor; and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the user equipment at least to perform: monitoring for presence of a clearance indication provided by a base station device serving a user equipment device, which indicates that the base station device does not intend to communicate in a subsequent channel occupancy time of a base station device frame period and clearance for communication by the user equipment device in at least one idle period of the base station device frame period, disabling communication by the user equipment device in the at least one idle period of the base station device frame period when the monitoring yields absence of the clearance indication, or enabling communication by the user equipment device in the at least one idle period of the base station device frame period when the monitoring yields presence of the clearance indication; and inhibiting observation of at least some downlink transmissions by and/or downlink channels from the base station device in at least part of a subsequent channel occupancy time of the base station device frame period when the monitoring yields presence of the clearance indication, or performing observation of at least some downlink transmissions by and/or downlink channels from the base station device in at least part of a subsequent channel occupancy time of the base station device frame period when the monitoring yields absence of the clearance indication. monitoring for presence of a clearance indication provided by a base station device serving a user equipment device, which indicates that the base station device does not intend to communicate in a subsequent channel occupancy time of a base station device frame period and clearance for communication by the user equipment device in at least one idle period of the base station device frame period, disabling communication by the user equipment device in the at least one idle period of the base station device frame period when the monitoring yields absence of the clearance indication, or enabling communication by the user equipment device in the at least one idle period of the base station device frame period when the monitoring yields presence of the clearance indication; and inhibiting observation of at least some downlink transmissions by and/or downlink channels from the base station device in at least part of a subsequent channel occupancy time of the base station device frame period when the monitoring yields presence of the clearance indication, or performing observation of at least some downlink transmissions by and/or downlink channels from the base station device in at least part of a subsequent channel occupancy time of the base station device frame period when the monitoring yields absence of the clearance indication.
