In some embodiments, an Information Handling System (IHS) may include a controller and a memory coupled to the controller, the memory having program instructions stored thereon that, upon execution, cause the controller to receive LCD display capability information from a display device, and determine from the received capability information, that a video stream sent to the display device has a lower frame rate than the capabilities of the display device. Using this information the instructions then increase the frame rate of the video stream by repeating each frame during a current time window of the frame.

Abstract: Apparatus and methods are provided for sidelink resource selection in unlicensed frequency bands. In one novel aspect, a combination of SL resource selection procedure and a listen-before-talk (LBT) procedure are used for resource selection in unlicensed frequency bands. In one embodiment, the LBT procedure is performed after the SL resource selection procedure. In one embodiment, the candidate resource selected by the SL resource selection procedure has an overbooking resource size larger than or equal to a resource size required for the SL data transceiving. In another embodiment, the overbooking resource size is dynamically determined based on one or more preconfigured conditions comprising an LBT failure probability, channel loading status information, and channel congestion control information. In yet another embodiment, the candidate resources are multi-consecutive-slot (MCSt) resources with configured multiple consecutive resource blocks.
