  • Patent number: 11101920
    Abstract: A transmitting device performs a channel assessment in a previous sub-frame in an unlicensed carrier. After a successful channel assessment, the transmitting device starts a data transmission. The transmitting device transmits a control message for indicating the data transmission in (E)PDCCH. The control message may include the starting time of the data transmission and/or at least one transmission characteristic in the previous sub-frame. The transmission device may transmit an initial control message for indicating a potential data transmission being started in the sub-frame in which the initial control message is transmitting. Method and apparatus enable (E)CCA to take place at any time, and data transmission to start earlier than the next sub-frame boundary after a successful completion of (E)CCA, thus improving the data transmission capacity, especially in circumstances when the maximum length of transmission is constrained.

  • Publication number: 20210220961
    Abstract: The present disclosure provides a tray assembly having a dual-structure. The tray assembly comprises an upper tray and a lower tray. The lower tray is capable of being easily disengaged from the upper tray by use of a dovetail joint that allows the lower tray to slidably move relative to the upper tray. The tray assembly also utilizes magnets to reduce the use of mechanical joints. The combination of the magnets together with the dovetail joint provides a quick and efficient way of sliding the lower tray in and out from the upper tray. The lower tray having a collection region collects any external, foreign materials generated during a chemical mechanical polishing/planarizing process. After the cleaning process, the lower tray can be slid back into the upper tray for use.
