  • Publication number: 20230239812
    Abstract: The present disclosure relates to transmit power control methods and apparatuses. In one example method, a network device determines a transmit power threshold corresponding to a spatial grid. The network device schedules a resource block (RB) or a carrier of one or more terminal devices corresponding to the spatial grid to control a transmit power corresponding to the spatial grid to be less than or equal to the transmit power threshold corresponding to the spatial grid.

  • Publication number: 20230155695
    Abstract: A network device obtains EMF strength of each grid in a first grid group. The first grid group includes M grids obtained by dividing a signal coverage area of the network device, and M is an integer greater than 1. The network device determines a second grid group based on EMF strength of the M grids. The second grid group includes at least a first grid and a second grid, a coverage area of the first grid is greater than that of the second grid, and EMF strength of the first grid is lower than EMF strength of the second grid. The network device monitors EMF strength of a coverage area of the second grid group based on the second grid group, to adjust the EMF strength of the coverage area of the second grid group.

  • Publication number: 20230138287
    Abstract: This application provides a method for sending a cell downlink fixed resource and a communications apparatus, which are applied to an RRU networking scenario. In the method, a first network device configures a first sending time in which a first cell of the first network device sends a cell downlink fixed resource, and controls the first cell to send the cell downlink fixed resource in the first sending time. The first sending time is different from a sending time in which a neighboring cell of the first cell sends the cell downlink fixed resource, and the first cell and the neighboring cell of the first cell carry a same frequency.

  • Publication number: 20210186885
    Abstract: The present disclosure provides powder coating compositions for pharmaceutical pellets which include one or more film forming polymers in powder form present in the composition in a range from about 1 to about 95% w/w. The compositions include one or more plasticizers in powder or liquid form present in the composition in quantity to lower the glass transition temperature of the coating composition to a temperature in a range from about 30 to 100° C. The compositions also include one or more one anti-static agents in powder or liquid form present in the composition in a range from about 0.1 to about 95% w/w as well as one or more flow enhancing agents in powder form present in the composition in a range from about 0.1 to about 25% w/w.

  • Patent number: 10588822
    Abstract: An apparatus for coating pharmaceutical particles such as drug dosage forms or pellets is provided which includes a drum assembly mounted for rotation about a cylindrical axis of the drum and which includes an outer drum section and an inner perforated drum section mounted concentrically on an interior of the outer drum section such that an annular chamber is formed between the perforated inner drum section and the outer drum section. Two or more baffle plates are attached between an outer surface of the inner perforated drum and an inner surface of the outer drum which are configured to act as baffles to restrain or regulate the flow of air which define two or more compartments depending on the number of baffle plates. One end of the drum assembly includes an end plate with a central aperture for use in loading pellets into the drum and provide access to coating constituents that are pumped into the drum interior during the coating process.
