摘要： A method of providing a mobile station with communication services through base station cooperation in a communication system. The method includes the steps of: receiving signals from two or more base stations; measuring a strength of each of the received signals; estimating an expected transfer rate of the mobile station; if the estimated expected transfer rate is below a predetermined reference value, selecting at least two bases stations in order of the strength of the received signal; feeding back information on the selected base stations and channel conditions thereof to a serving base station that is providing the mobile station with the communication services or to a base station that is to serve the mobile station; allocating power and resources to the mobile station by the selected base stations; and performing signal transmission/reception with the selected base stations by using the allocated power and resources.

摘要： A method for manufacturing first electrode of a capacitor of a semiconductor device is disclosed. After forming a polycrystalline layer composed of grains with microscopic structure to include an impurity in them, the polycrystalline layer is etched to cut the boundary portions of the grains, thereby allowing the surface of the polycrystalline layer to be rugged. The micro-trenches or micro-pillars are formed by using the oxide layer or an anisotropic etching after exposing the surface of the first rugged polycrystalline layer, and epitaxial grains are formed by epitaxial growth, so that cell capacitance can be further increased. The simple process allows the formation of a reliable semiconductor device having regularity and reproducibility, and capable of increasing and adjusting the cell capacitance easily.
