Abstract

An apparatus for a wireless communication system is connected to at least one user device (UE) via a sidelink for a sidelink communication. For a unicast transmission, the apparatus transmits a sidelink frame having a certain frame duration. A first part of the sidelink frame includes a control signaling. The control signaling indicates to the UE whether a feedback is to be returned to the apparatus. The feedback indicates a successful reception of data at the UE or a sidelink channel condition. If a feedback is desired, the apparatus transmits in the first part of the frame, using the control signaling, an indication that the feedback is to be provided by the UE such that a duration of the control signaling is shorter, by a remaining duration, than the frame duration, and receives from the UE, during the remaining duration, the feedback.
