Abstract: Methods, systems, and devices for wireless communication are described. A non-sidelink synchronization signal (SLSS)-transmitting user equipment (UE) may initiate a channel occupancy time (COT) including multiple contiguous slots and a gap slot. The non-SLSS UE may detect an SLSS UE (capable of transmitting sidelink synchronization signal blocks (S-SSBs)) and assume that the gap slot will be filled with an S-SSB. The non-SLSS may transmit a sidelink message during the COT after the gap slot, based on the assumption. Alternatively, based on the SLSS UE indicating that it is capable of transmitting the S-SSB, the non-SLSS UE may schedule transmission of the S-SSB such that the gap slot is filled. If the SLSS UE is incapable of transmitting the S-SSB, the non-SLSS UE may determine a method for transmitting the sidelink message during the already-initiated COT or during another COT.

Abstract: The invention discloses a method and system for preparing multi-compound ester insulating oil. The method utilizes vacuum esterification, involving esterification of pentaerythritol and fatty acid, followed by vacuum distillation, adsorption, washing, suction filtration, and vacuum drying to produce pure synthetic ester insulating oil. By detecting saturated fatty acid content, polarization strength, and closed-cup flash point, the most suitable natural ester insulating oil is selected. Ten different proportions of mixed ester insulating oils are obtained through blending and tested for mass and heat changes in nitrogen and air environments. Dielectric performance parameters at varying temperatures are analyzed to calculate activation energy. The resulting mixed ester insulating oil, NSE3 (85 vol % KA+15 vol % FR3), exhibits a high flash point, low pour point, and high AC breakdown voltage, offering excellent comprehensive performance.
