Abstract: Apparatus and methods are provided for determining epoch time in an NTN system resolving the SFN wrapping issue. In one novel aspect, the UE obtains epoch time information, determines the epoch-time SFN by selecting one SFN instance with the SFN value indicated in the epoch time information based on one or more epoch-time rules, wherein the epoch-time rules resolve epoch-time SFN ambiguity indicated by the received epoch time information, and derives the epoch time based on the determined epoch-time SFN. In one embodiment, the epoch-time SFN is determined based on the receiving-SFN/SIBx and the SFN value of the epoch-time. The epoch-time SFN is a current or next upcoming SFN with the epoch-time SFN value after the receiving-SFN. The epoch-time SFN is a nearest SFN to the receiving-SFN with the epoch-time SFN value.

Abstract: Laser ablation processing method for debris-free and efficient removal of materials comprises the step of using a refrigeration device to condense the water vapor and form a thin frost layer on the materials at temperatures below the freezing point. The residual debris produced during the ablation process deposits on the frost layer that covers the material, which is easily removed when the frost layer melts. At the same time, the frost layer in the laser irradiation area melts to a liquid layer, which can effectively reduce the deposition of debris on the inner wall of the groove and thus improve the efficiency and quality of laser ablation. The method is applicable to debris-free laser processing on an arbitrary curved surface.
